• Frequently Asked Questions

If the Wi-Fi settings screen on your Android phone or tablet says there's been an authentication problem, you won't be able to reach the internet properly. Below are several things you can try to fix the issue and get back online.

Specific steps may differ based on the operating system version you're running, but the basic process will be the same.

There isn't a single, clear reason for this problem, but here are some ideas we'll look into:

• You're using the wrong password.
• A glitch or failure on your phone or network hardware.
• A poor connection to the router.
• Network settings are corrupt.
• Your phone is having trouble dealing with the frequency band.

How Do I Fix a Wi-Fi Authentication Error?

Below is a list of everything you should try. We've gathered all the best solutions from the huge variety of users who have experienced this error. Be sure to work through this list in the order we've arranged it so you're trying the easier solutions first.

Turn airplane mode on and then off again . Toggling this feature on and off will essentially reboot the wireless radios and forcibly attempt to establish a new connection to the Wi-Fi network.

Assuming the network and your phone are working correctly, this is the most likely fix for this issue if you know you didn't make any changes to the Wi-Fi password recently.

Restart your phone . Restarting your phone (also called rebooting) is easy to do, and often fixes problems like this one.

"Forget" the Wi-Fi network from your phone by deleting it from the list of saved networks. Do this by accessing the Wi-Fi settings, and then open the gear/settings icon next to the network that is displaying the error, and choose Forget .

After doing that, reconnect your Android device to Wi-Fi by entering the password again manually.

Complete this step even if you're positive it's the correct password. Even if you've used this Wi-Fi network hundreds of times in the past, rebuilding it like this is a helpful step before we get into the more complex ideas below.

Reset the phone's network settings. A reset of network settings deletes all network-related information (not just the one you "forgot" in the previous step), including all your saved Wi-Fi networks and other related data.

The goal here is to reset as much as possible without deleting any of your personal files (1the last step below). Do this through Settings > System > Reset options > Reset Wi-Fi, mobile & Bluetooth .

You'll need to try to connect to the network again after this step.

Troubleshoot this as a slow internet connection . Things like bandwidth overload and signal interference might be at play and causing the authentication issue.

Restart the network hardware . You might not have the authority to do this if you're using a public network (you know, at a Starbucks, library, etc), but make every attempt you can to complete this step.

After addressing the password and phone itself, there's not a lot left to blame for the authentication problem other than the router. This is especially true if you can get on Wi-Fi just fine on other networks, and this specific network is the only exception.

Restart and reset are very different things . This particular step is for restarting/rebooting the network, which isn't really different from restarting any tech device.

Check how many devices are running on the network at once . Although it's unlikely, especially on a home network, to reach the maximum devices supported by the router , this could be the reason your device is showing an authentication error.

Reset the network hardware . This will delete all customizations made to the router since it was first set up.

After completing this, you'll need to create the Wi-Fi network again, and then reconnect your phone to it (see Step 3).

This is a helpful step if you're able to connect to Wi-Fi for just a short time, after which you get the authentication error. Since a full reset forces you to create a new Wi-Fi password from the router , it'll kick off every other device on the network and reduce the chance you're experiencing an IP address conflict .

If your network hardware supports it, separate the 5 GHz and 2.4 GHz networks if your router is broadcasting on both frequency bands with the same SSID and password. Some users have had luck fixing this Wi-Fi authentication error by changing the network name and password for one of the bands.

What might be happening is the phone is getting confused or going into hyper-secure mode when it sees two different networks with the same credentials, and it prevents you from accessing either one.

See our guide on how to change the Wi-Fi channel to see where these settings are on a typical router.

Change the Wi-Fi channel to fix the Wi-Fi authentication problem. Use the link at the bottom of Step 9 to learn how to do this.

Choosing a different Wi-Fi channel number can help avoid interference , especially if there are several other Wi-Fi networks within range.

Install a free Wi-Fi app to see what channel you and your neighbors are using.

Set up your phone with a static IP address . For whatever reason, your router might be having trouble assigning your device a working address, so choosing a static IP address prevents it from changing and relieves the router from having to do it through DHCP .

Check for Android OS updates . This is more of a stretch than the rest of these steps, but there might be an update you have yet to apply which fixes this particular issue. It's worth a shot, at least, before moving on to the last step below.

Factory reset your phone . This is the last thing you have control over on your phone which could fix this issue. It will completely erase all customizations on your device, including all your locally saved media files, apps, etc.

Do not jump to this step without first completing all of the above. You need to make sure the network itself isn't having a problem before taking this drastic "delete everything and start over" step. Reserve this for the worst case scenario, one where you know the phone is to blame and not the network.

Contact your device manufacturer (e.g., Google if you're on a Pixel, Linksys if that's your router brand), contact your network administrator, and/or contact the ISP that delivers your internet.

When you talk to tech support , be sure to describe all you've already tried (everything listed above), because at this stage you've done all you can do, and what's left is giving those companies a heads-up, since the fault appears to lie with one of them.

Depending on whom you reach out to, they might be able to attempt a hardware repair if your phone is broken, or your internet service provider or hardware maker can investigate your router/modem further for Wi-Fi related issues. In some cases, the network admin might need to make some security changes on their end .

If your Wi-Fi network isn't showing up , it could be because the router is too far away, the network adapter is disabled, or the router was not restored correctly after losing power. Other possible causes include viruses or object interference.

If your Wi-Fi connection keeps dropping , it could be due to an overloaded network, interference from other Wi-Fi signals, or the router being out of range. Make sure that you're connected to the right Wi-Fi network.

If your Android can't connect to Wi-Fi , your device's software or hardware could be malfunctioning, your Wi-Fi network could be having issues, or you're too far away from the router.

If you have Wi-Fi but no internet connection, the problem usually lies in your devices rather than your internet service provider. Restart the router and modem. If you still have no internet after restarting, you can try several other troubleshooting steps .

If you are an Android user, you might have occasionally encountered an authentication error when connecting to Wi-Fi. This means that even after entering the right password and having connected to the Wi-Fi network previously, you are unable to connect to it now even after trying to reconnect. If this sounds a bit too familiar, this guide can help you get out of this problem on your device.

There are multiple reasons that could be causing this issue, leaving you confused. But not anymore. In this guide, we will help you understand what might be causing it and 12 ways to fix Wi-Fi authentication problems on Android. Let’s get into it.

Reasons for the Wi-Fi Authentication Error

There’s no clear path on what could be the issue’s root cause, but there are multiple ways that may lead to it. We are listing some common ones below.

• Poor network connectivity.
• Incorrect password. 
• Incorrect IP address.
• Too many devices are connected, and the router has reached its connection threshold. 
• A glitch on your phone’s or network’s hardware.
• The Wi-Fi (network) settings might have gotten corrupted.
• Lastly, there could be a mismatch in frequency bands. 

Note: We used OnePlus 7T running Android 11, Huawei Nova 3i running Android 8, and Nokia’s router to build this guide, but you can follow the same steps on your Android devices and routers. However, some steps and screenshots might look different.

How to Fix Wi-Fi Authentication Problems on Your Android Device

Now that you know the reasons that might be causing the issue, let’s get to fixing it with the below 12 ways.

1. Turn on Airplane mode

It is one of the easiest and sometimes the most efficient solutions. Toggling on the Airplane mode causes the hardware to shut off its wireless components, which cuts off your connections and reboots them. There are two methods involved in this step. Let me explain. 

Step 1 : Open your phone Settings and tap on Wi-Fi & Network.

Step 2 : Toggle on Airplane mode. Wait a few seconds and toggle off Airplane mode.

Now, your phone’s network hardware has been rebooted. So, try connecting it to the Wi-Fi again; you should be able to get in. Just in case you’re facing the same issue, follow the below steps.

Step 2 : Toggle on Airplane mode.

It will turn off your mobile network and also your Wi-Fi. 

Step 4 : Now, turn on Wi-Fi and try connecting to your network

If you can connect to your Wi-Fi without any Authentication error, follow Step 5. If you’re still unable to connect to your Wi-Fi, try resetting the Wi-Fi connection covered in the next section.

Step 5 : After establishing the Wi-Fi connection, toggle off Airplane mode.

This enables the phone to connect to a mobile network without interrupting the Wi-Fi connection. 

2. Reset Wi-Fi Connection

Sometimes, the Wi-Fi settings get corrupted. The easiest way to resolve the connectivity problem is to remove the network or Wi-Fi from your phone’s saved networks . Make sure you have the password of the Wi-Fi you’re removing from the network before following the below steps.

Step 1 : Open the phone Settings and select Wi-fi & Network,

Step 2: Tap on Wi-Fi and go to Saved networks.

Step 3 : Select the Wi-Fi you want to reconnect with and tap Forget.

That’s it! The Wi-Fi network will be removed from your phone. Now, you have to reconnect it again to revive the network flow onto your Android device. If the problem persists, don’t worry. There are more fixes to help you. Read on.

3. Restart Your Phone

It is a no-brainer method. We all know that restarting the device is the most efficient method if things get stuck. This is especially true for any consumer tech products and services. 

Step 1 : Close all your running apps.

Step 2 : Long-press the power button and tap on Restart.

If the restart didn’t resolve the issue, then keep reading. The below-mentioned fixes should help.

4. Reboot the Router

Much like the earlier step in which we restarted the phone, in this step, we will be restarting the Wi-Fi router. It is again a straightforward process that clears out any snags in the router’s settings. 

All you need to do is turn off the Wi-Fi router and wait for a few minutes before turning it back on. You might need to give it some time for it to function. Once it is set, try connecting your phone to check if the network is established. 

5. Check for Duplicate Wireless Network Names

One of the most common errors users make is forgetting the password or entering the wrong password, leading to a Wi-Fi authentication error on the phone. So, make sure you are entering the correct password.

If you have multiple access points/Wi-Fi routers with the same name, you will inevitably face this authentication error on your phone one or the other day. To overcome this, avoid keeping the same SSID for all the routers. Differentiate them with a name or number or even based on their frequencies like ex: drawing room, bedroom, or home 1, home 2. On the other hand, you can also keep one password for all the Wi-Fi routers.

6. Check the Maximum Supported Devices

It is improbable that your router will reach the maximum supported device limit, especially if it is a private network. But, at times, when there are a lot of guests, it is expected that the internet will slow down. The router’s threshold will break, which could be why it shows an authentication error on the phone. Here’s how to check how many users are connected to your router.

Finding the Router’s IP Address

Most routers have a default IP address of 192.168.0.1 or 192.168.1.1. Let’s begin by finding the router’s IP address if these didn’t work.

Step 1 : Press Ctrl + R to open the Run command. 

Step 2 : Type CMD to open the command prompt.

Step 3 : Now, type ‘ipconfig’ and press enter.

Step 4 : You will find your router’s default IP address. Copy and save it somewhere.

Now, let’s check how many users are connected.  

Step 1 : Enter the default IP address on any browser and log in using the router’s credentials.

Step 2 : Go to Wireless to check the number of users connected to the wireless network.

If you don’t know the credentials, check your router’s back. It is often in the admin/admin or admin/password format. However, if you have changed that previously, enter the new credentials.

7. Reset the Phone’s Network Settings

If none of the above steps fixed the issue, this one likely will. This step will reset the phone’s network settings and start from scratch. Let’s begin.

Step 1 : Open the phone’s Settings and go to System.

Step 2 : Open Reset options and tap on ‘Reset Wi-Fi, mobile & Bluetooth.’

Step 3 : Tap Reset Settings and confirm it.

All the Wi-Fi settings will be reset, including mobile data and Bluetooth settings.

8. Use the WPS Push Button

Also known as Wi-Fi Protected Setup, this is an advanced feature that lets anyone with the router access it, which bypasses the credentials (username and password) part. Follow along. 

Step 1 : Go to the phone’s settings and tap on ‘Wi-Fi & Network.’

Step 2 : Tap on Wi-Fi, select More, and choose ‘Advanced Wi-Fi settings.’

Step 3 : Now, select the WPS connection.

  I’m using Huawei Nova 3i for this method as the WPS Push button wasn’t there in OnePlus 7T.

You will have a prompt instructing you to press the WPS button on your router. Once the process is complete, this should resolve the authentication issue on your Android.

9. Change Security Protocol

It is another handy option that you will generally miss out on. You might have encountered a scenario where you entered the correct password, but the network wouldn’t allow you in. What to do? Follow these steps.

Step 1 : Log in to the router.

Step 2 : Go to the Network or Security Protocol and c hange the settings from WPA to WPA2.

Step 3 : Now, on your Android device, open the Wi-Fi settings.

Step 4 : Tap on the Wi-Fi name and select Forget.

Step 5 : Now, connect to the network again.

You should be able to get in.

10. Reset the Network Hardware

This is the last resort; reset the router. Mind you, all the customizations you made to the router since its setup will be deleted, and you might have to set it up again. Here’s how to do it. 

Almost all the routers have a manual button at the back to reset the router. All you need to do is press the button long enough until the lights go off and turn back on. That’s when the router will reset, and you will have to set it up again to use it. 

11. Changing the IP Address From DHCP to Static

Most of the routers on the market use the DHCP protocol to allocate Internet Protocol (IP) addresses and other configuration information like subnet mask and default gateway. However, sometimes DHCP assigns the same IP address to multiple devices, giving rise to IP conflicts and disrupting the network.

This issue can be fixed by assigning a static IP address to your device, which in this case, is your Android device. Once your device gets a predetermined IP address, DHCP gets out of the picture. Let’s get to the steps.

Step 1 : Go to the phone Settings and select Wi-Fi & Network.

Step 2 : Go to Wi-Fi and select the Wi-Fi network. Now, tap the pencil icon at the top right.

Step 3 : Tap Advanced, go to IP settings and select Static.

Step 4 : Enter the IP address that is not already in use and tap Save.

Leave the rest of the details as is, or you can enter 8.8.8.8 in DNS 1 and 8.8.4.4 in DNS 2 fields if you want to use Google’s DNS. 

12. Update the Device Software

This is not a typical case, but there are times when software updates on your Android device could stall the wireless connection. So, if you haven’t updated your Android device for a while now, that could also be the reason for the authentication error on your Android device. Here’s how to check for updates.

Step 1 : Go to the phone’s Settings and select System.

Step 2 : Now, go to System updates and check for pending updates.

The software updates bring in patches and bug fixes, crucial for your Android device’s security. If you see any pending updates, update them and sort this issue once and for all.

5 ways to fix Wi-Fi authentication problems on an Android when your device won't connect to the internet

• A quick fix to Wi-Fi authentication problems on Android is to toggle airplane mode on and off, or "forget" the Wi-Fi network and reconnect to it. 
• You might sometimes encounter an authentication error while trying to connect to Wi-Fi with your Android device even if it's a network you have used before and your password is correct. 
• Here are the most common ways to fix Wi-Fi authentication problems on an Android device.

Occasionally, you might have trouble connecting to a Wi-Fi network even though it's a network you routinely use and all your settings should be correct, including the password. This Wi-Fi authentication error is frustrating because it's not always clear why it's happening. 

How to fix Wi-Fi authentication problems on Android

The next time a Wi-Fi authentication issue happens to you, here are the most common ways to troubleshoot and solve the error. 

Toggle Airplane mode

As with all kinds of troubleshooting, you should start with the easiest possible solutions and, if they don't work, make your way through progressively more complex solutions. The easiest thing you can try is to put your Android phone in airplane mode, which disables most or all of the radios on your device. It's akin to rebooting your Wi-Fi radio.

To do that, swipe down from the top of your phone to see the quick access icons, and tap "Airplane mode." (The icon will be shaped like an airplane.) Wait several seconds and tap the icon a second time to turn it off. Check your Wi-Fi and see if it now connects properly. 

Forget and reconnect to the Wi-Fi network

If the Wi-Fi settings for this network have become corrupted, you might be able to get up and running by "forgetting" the network and then reconnecting to it. You'll need to know the Wi-Fi password before you begin. 

1. Start the Settings app.

2. Go to your Wi-Fi settings. Where to find this depends on which Android phone and OS version you are using, but generally it will be found in "Wireless & networks" or "Connections."

3. Tap and hold the Wi-Fi network you are trying to connect to or tap the gear-shaped settings icon. Then choose "Forget this network."

4. After a moment, the network will appear in the list of available networks. Tap it and enter the password to reconnect. 

Reboot your Wi-Fi router

If you are unsuccessful in trying to connect to your own home Wi-Fi network, you have another option: You can reboot the router. Simply unplug the router and leave it unpowered for about two minutes. Then plug it back in again and check your connection. 

Change the network from DHCP to Static

If you still can't authenticate, you can try forcing your Android phone to use a static IP address instead of dynamically choosing one when you connect, which is the default and much more common. 

1. Open your Wi-Fi settings in the Settings app, like you did when forgetting the network, tap and hold the network or choose the settings icon.

2. Choose "Modify this network" or "Advanced" depending upon your Android phone and look for "DHCP." 

3. Tap "DHCP" and, in the dropdown menu, choose "Static."

4. Tap "Save."

Now that your phone is using a static IP address to reach your Wi-Fi network, try again. 

Reset your network settings

If none of those options work, you have one last option: You can try to reset all your network settings. 

1. Start the Settings app. 

2 . In the search box at the top of the Settings page, type "Reset." In the search results, find and tap "Reset network settings." This will wipe out all your Wi-Fi, cellular, and Bluetooth settings, so you will need to reconfigure those networks.

3. Tap "Reset network."

Seeing an authentication error while connecting your Android device to a Wi-Fi network? Unfortunately, this is a pretty common issue. It can even happen while connecting to a network that you've used in the past.

Luckily, there are several ways to get around this problem and successfully connect your phone to a Wi-Fi network. Check out these fixes below.

1. Toggle Airplane Mode

An easy way to get around Wi-Fi authentication errors is to toggle airplane mode on your Android phone . When you do that, your phone disconnects from all the networks you're connected to.

You can then disable airplane mode to reconnect to your chosen Wi-Fi network. There's no guarantee that this method will fix the error, but it only takes a moment, so it's worth a try. Here's how to do it:

• Launch the Settings app on your Android phone.
• Tap on the option that says Wi-Fi & internet . This option may have a slightly different name depending on your Android device.
• Turn the toggle for Airplane mode to the On position.[gallery columns="2" link="none" size="2-column-gallery" ids="980961,980960"]
• Wait about a minute, then turn the toggle back to the Off position.

Your phone should hopefully now connect to any saved Wi-Fi networks nearby. To access airplane mode more quickly in the future, drag down from the top of the screen twice to access the Quick Settings panel and tap the Airplane mode item.

2. Check the Wi-Fi Password

An authentication error is often the result of entering an incorrect Wi-Fi password. If you aren't sure what your password is, or if someone has changed it, you'll need to find the correct password for your wireless network.

If you don't manage the network, ask someone who knows the password. If this is your home network, you can head into your router's settings menu and find the password for yourself:

• Open a browser and access your router's settings page by entering its IP address. This is often 192.168.1.1 , but varies across devices. Enter that address in your address bar and press Enter . If it doesn't work, see our beginner router FAQ for help.

• Once you're logged in, click on Wireless Settings in the list of options. This may be called something else in your router, but you should recognize it as similar.

• Enter the newly found password on your Android phone and it should connect to the network as usual. If you can't view the existing password, change it to something new and enter that on your phone instead.

If you can't use the above method, it's possible to find your Wi-Fi password using Windows 10 .

3. Restart Your Wi-Fi Router

Wi-Fi routers can sometimes experience hiccups. When that happens, your router could drop the connection for your devices, prevent new devices from connecting to the network, and have other problems.

Your authentication error could be the result of a malfunctioning router. Fortunately, fixing that is pretty easy. Simply turn off your router by unplugging it, keep it off for at least a minute, and then turn it back on.

Your phone should then connect to the network without any errors.

4. Forget and Rejoin the Wi-Fi Network

Sometimes, removing the Wi-Fi network and then rejoining it fixes authentication errors. As long as you remember the password for your network, this is simple to do:

• Open the Settings app on your phone.
• Select the option that says Wi-Fi & internet and tap Wi-Fi on the following screen.
• Find your Wi-Fi network in the list and tap on the settings icon next to it.
• On the screen that follows, you'll see a button that says Forget . Tap this option and your chosen Wi-Fi network will disappear from your device.
• Go back to the previous screen and tap on your network.
• Enter the password for your network and tap Connect to rejoin the network.[gallery link="none" size="2-column-gallery" ids="980961,980964,980965"]

5. Use a Static IP Instead of Dynamic

Most routers use DHCP, which automatically assigns an IP address to each device on the network. Sometimes, the DHCP feature doesn't work as it's supposed to, which will cause issues with your network.

Wi-Fi authentication and IP conflict issues are often the results of malfunctioning DHCP. To fix it, you can assign a static IP address to your Android phone. This way, your phone will have its own predefined IP address and won't rely on the router to get an IP.

Don't worry if this sounds a bit technical; it's pretty easy to do.

• Access the Settings app on your phone.
• Tap on Wi-Fi & internet and choose your Wi-Fi network from the list.
• Tap the pencil icon at the top to edit your Wi-Fi settings.
• Select the Advanced options menu to show several new options.
• Choose Static from the IP settings dropdown menu.
• In the IP address field, you need to enter an IP address that's within the range of your allowed IP addresses and not in use already. If you don't know how to pick an address properly, read our guide to static IP addresses first.[gallery link="none" size="2-column-gallery" ids="980966,980968,980967"]
• Enter the IP address of your router in the Gateway field. If you don't know it, see the router FAQ article linked earlier.
• Leave the DNS fields blank to use the defaults or enter 8.8.8.8 in DNS 1 and 8.8.4.4 in DNS 2 fields if you want to use Google's DNS. Then tap Save .

6. Reset Wi-Fi Settings on Your Phone

Improper Wi-Fi settings can lead to authentication errors. If you've tried all of the above and still can't connect, resetting them to the default should hopefully clear up the issue for you.

Android provides you with an option to reset all your network settings at once. When you do this, you'll lose all saved network data, such as VPN configurations, saved Wi-Fi networks, and Bluetooth devices. You'll have to reconfigure them later, so make sure you're OK with proceeding:

• Open Settings on your phone and tap on System at the bottom.
• Select Reset options on the following screen.
• Tap on the option that says Reset Wi-Fi, mobile & Bluetooth to reset your network settings.[gallery link="none" size="2-column-gallery" ids="980971,980969,980970"]

Once the settings are reset, connect your phone to the Wi-Fi network as you normally would.

7. Update Your Android Software

If you haven't updated your Android device in a long time, that could be why you see authentication errors on your phone. Newer operating system versions often patch bugs from older versions, which is why it's important to keep your Android phone up to date.

Here's how to find, download, and install software updates on your device:

• Go to Settings and tap on System at the bottom.
• Select the System updates option.[gallery link="none" columns="2" size="2-column-gallery" ids="980971,980969"]
• If an update is available, you should be able to download and install it on your phone.

8. Factory Reset Your Device

No matter the issue, if nothing else works, your last resort is to reset your phone to factory settings. This procedure erases all your data and settings stored on the device, so you'll be starting from scratch when it's done.

If you're still seeing Wi-Fi authentication errors at this point, this nuclear option is your last resort. Be sure to back up your phone before you reset it to avoid losing precious data.

• Head to Settings > System > Reset options on your phone.
• Tap on the Erase all data (factory reset) option.[gallery link="none" size="2-column-gallery" ids="980971,980969,980970"]
• Once your device is reset, try connecting to your Wi-Fi network before customizing any other settings.

5 Ways to Fix WiFi Authentication Error

If you have previously connected to a particular Wi-Fi network, your mobile device should instantly connect to it on other attempts. However, the Wi-Fi settings may pop-up error messages like “Authentication error occurred” or “ Authentication problem” whenever you try to connect to that network.   

Most of the time, the Authentication error occurs if the Wi-Fi admin has changed the password, and you try to connect to that network using an old password. Besides, network bugs and weak connections can also cause this issue. Nevertheless, you can try various methods so that you can connect to your Wi-Fi in no time.

How to Fix Wi-Fi Authentication Error?

As a preliminary fix, you can try restarting your router and toggling the Wi-Fi settings. However, if you still get this error message, you can move forward with the fixes below.

Forget Network And Reconnect

When you forget the connected network, it will forcibly disconnect and remove your device’s password and IP address. But you can join that Wi-Fi again after entering the correct password.  

Follow the below steps to forget the network.

• Open your Wi-Fi settings.

• Once you are disconnected, go to the Wi-Fi settings.
• Select your Wi-Fi and enter the correct password to connect to it. 

Force Reboot Your Phone

Occasionally, you can get this error message due to your device’s bugs. For that, you can force reboot your phone. This method often works to fix minor issues from the software side as it will clear the temporary data in the memory, which helps to start fresh once the device boots up.

• Once the screen goes off, continue pressing the Power button until you see the android or your device’s manufacturer logo.

Clear Android System Cache 

This method will basically just delete the temporary files of your Android system. You can try clearing this to see if it could work for you.  

• Open settings.
• Scroll down and tap on Apps .
• Select Manage apps .

Reset Network Settings

If the network-related bug is causing trouble from connecting to the Wi-Fi, this can be an effective way to tackle it by specifically resetting its settings . As the name suggests, it will remove previously connected networks related to Wi-Fi, Locations, etc.

But you can reconnect to such networks anytime. So, give this method a try.  

• Launch the settings.
• Go to Connection & sharing .

• Then, tap OK to confirm.

Scan With the QR Code

One of the above methods should work for you to fix this authentication error. However, if you are still unable to connect to Wi-Fi by entering the password, you can use your device’s QR scan to connect . Simply open the QR code of your other device that is connected to the Wi-Fi. Then, open the QR scanner from your device and point it to that code. You should be able to connect to your internet. 

But remember, if you are using an old android device, it may not support the QR feature.

5 ways to fix Wi-Fi authentication problems on an Android when your device won't connect to the internet

Dave johnson   .

• A quick fix to Wi-Fi authentication problems on Android is to toggle airplane mode on and off, or "forget" the Wi-Fi network and reconnect to it.
• You might sometimes encounter an authentication error while trying to connect to Wi-Fi with your Android device even if it's a network you have used before and your password is correct.
• Here are the most common ways to fix Wi-Fi authentication problems on an Android device.

Occasionally, you might have trouble connecting to a Wi-Fi network even though it's a network you routinely use and all your settings should be correct, including the password. This Wi-Fi authentication error is frustrating because it's not always clear why it's happening.

How to fix Wi-Fi authentication problems on Android

The next time a Wi-Fi authentication issue happens to you, here are the most common ways to troubleshoot and solve the error.

Toggle Airplane mode

As with all kinds of troubleshooting , you should start with the easiest possible solutions and, if they don't work, make your way through progressively more complex solutions. The easiest thing you can try is to put your Android phone in airplane mode, which disables most or all of the radios on your device. It's akin to rebooting your Wi-Fi radio.

To do that, swipe down from the top of your phone to see the quick access icons, and tap "Airplane mode." (The icon will be shaped like an airplane.) Wait several seconds and tap the icon a second time to turn it off. Check your Wi-Fi and see if it now connects properly.

Forget and reconnect to the Wi-Fi network

If the Wi-Fi settings for this network have become corrupted, you might be able to get up and running by "forgetting" the network and then reconnecting to it. You'll need to know the Wi-Fi password before you begin.

1. Start the Settings app.

2. Go to your Wi-Fi settings. Where to find this depends on which Android phone and OS version you are using, but generally it will be found in "Wireless & networks" or "Connections."

3. Tap and hold the Wi-Fi network you are trying to connect to or tap the gear-shaped settings icon. Then choose "Forget this network."

4. After a moment, the network will appear in the list of available networks. Tap it and enter the password to reconnect.

Reboot your Wi-Fi router

If you are unsuccessful in trying to connect to your own home Wi-Fi network, you have another option: You can reboot the router. Simply unplug the router and leave it unpowered for about two minutes. Then plug it back in again and check your connection.

Change the network from DHCP to Static

If you still can't authenticate, you can try forcing your Android phone to use a static IP address instead of dynamically choosing one when you connect, which is the default and much more common.

1. Open your Wi-Fi settings in the Settings app, like you did when forgetting the network, tap and hold the network or choose the settings icon.

2. Choose "Modify this network" or "Advanced" depending upon your Android phone and look for "DHCP."

3. Tap "DHCP" and, in the dropdown menu, choose "Static."

4. Tap "Save."

Now that your phone is using a static IP address to reach your Wi-Fi network, try again.

Reset your network settings

If none of those options work, you have one last option: You can try to reset all your network settings.

2 . In the search box at the top of the Settings page, type "Reset." In the search results, find and tap "Reset network settings." This will wipe out all your Wi-Fi, cellular, and Bluetooth settings, so you will need to reconfigure those networks.

3. Tap "Reset network."

• Top 13 Solutions to Fix Android WiFi Authentication Problem

Did you try to connect to a Wi-Fi network recently, but got an authentication problem? Or, did you try to connect your Android device to a Wi-Fi network that you have used with the smartphone before, but authentication error occurred? Don't worry, because this issue is common in some Android smartphones and can be fixed easily.

The authentication error may occur suddenly even if you are sure that you have used the correct Wi-Fi password. This can be annoying when you want to use the internet urgently and it can be even worse when you are unable to use your mobile network. This problem can occur because of various reasons. There can be an issue with the wireless network or with your Android phone or both.

We have given the top 13 solutions in this guide to solve the authentication error Wi-Fi problem. You just need to follow these steps carefully.

Part 1. What Does It Mean When Wi-Fi Says Authentication Problem?

Part 2. why does authentication error occur with wi-fi on android, part 3. 6 advanced ways to fix authentication problem on android.

Part 4. 7 Common Checks to Fix Android Wi-Fi Authentication Problem

The Wi-Fi authentication error occurs when you are unsuccessfully trying to connect to any Wi-Fi network with the correct password.

Normally, when you try to connect to a Wi-Fi network, the device will connect to that network and save the password. But with this problem, you will get a notification telling that it is authenticating and after a few minutes, you will see "authentication problem" under the network name you are trying to connect to.

When you are trying to connect to a Wi-Fi network, the device will first send a connection request, in an encrypted form, along with the password to the router. Then, the router will compare the password stored on it with the received data.

If the data matches, it will send a signal and the device will get connected. If it doesn't, you will get an authentication error. So, the Android Wi-Fi authentication problem will not let your device connect to the Wi-Fi network.

The Wi-Fi authentication problem can occur due to multiple reasons. Let's see the possible reasons for this error.

Whenever the router malfunctions, your device will not connect to Wi-Fi and will deliver a notification saying an authentication error.

Have you recently updated your device? If yes, the issue might be with its drivers.

The connection between the device and router must be stable otherwise the authentication error can occur.

Are you sure you are connecting to the correct Wi-Fi network? You may try to connect to a network with the duplicate name for many times. In such a case, you will get the authentication error.

Sometimes, based on user's settings, the number of devices that can use the Wi-Fi network is limited. Your device won't connect to the network if that number exceeds.

Most users do not want to waste time trying too many ways to fix this, so the advanced ways are recommended first.

1. Change Wireless Network Configuration from DHCP to Static

An IP conflict can cause any type of connection to drop, regardless of the wireless router you use. Even the Android devices can face such kind of issue, giving you authentication error. Solve this issue by changing the setting from DHCP, which is the default setting, to Static IP.

Step 1: Open Settings and choose the Wi-Fi connection.

Step 2: Long press on the Wi-Fi name and choose Modify Network.

Step 3: Check the Show Advanced Settings box and then look for IP settings. Now, change the network from DHCP to Static.

Step 4: You will see an IP address field below. Note down and save the information that is in the static IP address field and then delete it.

Step 5: After a few seconds, re-enter the same information and then save it.

Contact your service provider if you are unsure of the settings that are displayed.

2. Update Android OS

Always make sure that your Android OS is updated to the latest version. When you don't update the device, the chances are that many of the bugs will not be solved.

Step 1: Go to Settings -> About Phone.

Step 2: The "System Updates" option will be displayed. This will show if there is an update available. In some Android models, there will be a separate tab for System Update in the Settings.

Step 3: Now, if there is an update available, download the update first and then install it.

Step 4: You will be asked to reboot the device. Confirm and check if the issue is solved.

3. Use WPS Push Button

WPS, also known as Wi-Fi Protected Setup, is a security standard for creating a home network without any password.

Step 1: Go to Settings -> Wireless & Networks -> Advanced Settings. Depending on your modes, you can find multiple WPS options.

Step 2: Tap on a WPS Push-button. WPS setup, waiting for configuration from your router, will appear on your screen.

Step 3: On your router, press the WPS button and wait for the connection to establish.

4. Use A Specialized Android System Repair Tool

Sometimes this authentication error will occur due to unknown software problems, so the best way is to rely on a professional Android system repair tool to help you. Here iMyFone Fixppo for Android is highly recommended. It has the highest repairing rate and speed, so all related Android issues can be solved within minutes.

5. Factory Reset Your Android Device

When you have tried all the possible solutions for solving this problem and still you are getting Wi-Fi authentication error, the last option is to factory reset your Android smartphone. Please note that this method will erase all the data on your device.

When you perform a factory reset, all the Android apps and data will be removed and all the settings will be reset to default. So before performing the factory reset, make sure that you back up all the personal data of your device.

6. Contact Your Mobile Carrier

Even after trying all the methods if you see Wi-Fi authentication error, you need to contact your mobile carrier to check whether there is something wrong with the hardware. Don't forget to mention the solutions you have already tried for solving this error so that you don't have to go through the above methods again.

Part 4. Common Checks to Fix Android Wi-Fi Authentication Problem

Just like most of the issues, there cannot be a single solution for the Wi-Fi authentication problem. If you want to use the simple ways first, try these following solutions one by one for solving the Android Wi-Fi authentication problem.

1. Reset the Wi-Fi Network

To solve this error, the first thing you can do is to reset the connection between the router and the Android device. This solution has helped many users in solving the Wi-Fi authentication error. When you reset, many other network-related issues also get solved.

Step 1: Open Settings and open Wi-Fi under Network Connections.

Step 2: Multiple Wi-Fi connection names will be listed. Find the one you are trying to connect to and then long-press on it. Two options will be shown-Forget Network and Modify Network.

Step 3: Choose the Forget Network option.

Step 4: Now enter the password and try to reconnect to the Wi-Fi network. Check if the device is connected to the network.

2. Restart the Router

Sometimes the electronic devices start working correctly when restarted. All the elements in the device will start afresh, thereby solving the issues you are facing. So, try to restart the router to see if you are able to connect your device to the Wi-Fi network.

Step 1: Press the switch and turn off the wireless router. Wait for a few minutes and then turn on the router.

Step 2: It will take time before any device can connect to the router.

Step 3: Now, connect your device and check if the connection is established.

3. Reset Network Settings

One of the simplest solutions is to reset the network settings of your Android device. All the Wi-Fi, Bluetooth and mobile network settings will be reset to the factory settings.

Step 1: Open Settings and go to Backup & Reset.

Step 2: Next, go to the Network Reset settings option.

Step 3: Tap on Reset Settings and wait for the process to complete.

Step 4: Once the process completes, open the Wi-Fi settings and try to connect to the Wi-Fi network.

4. Turn Airplane Mode on/off

Many of us use the Airplane mode either when we want to play a game without any disturbance or when we board a plane. Turning on Airplane mode can be useful because often the mobile network signal may interfere with the wireless network. When you enable the Airplane mode, the RF signal transmission on your phone is turned off.

Step 1: Open Settings on your device and turn off the mobile and Wi-Fi network. You can also do this by pulling down the quick settings menu.

Step 2: Now, turn on the Airplane mode.

Step 3: With the Airplane mode on, turn on Wi-Fi on your device and connect to the wireless network. If your device gets connected to the Wi-Fi network successfully, you can open settings and turn off the Airplane mode.

5. Check the Number of Supported Devices

Few modems can support only a certain number of devices. You need to check through the manufacturer or the service provider. Now, go to the Wi-Fi router settings and check the maximum number of devices that can connect to the wireless network. Increase the number of devices and save the settings.

6. Check Network Security Type

Sometimes the network security type can be a reason for this error. If you know the username and password of the wireless router, you can easily change the network security type.

If WPA is the security protocol, change it to WPA2 and vice versa. Now, in your Android smartphone, follow the steps given above and tap on Forget Network. After a few minutes, reconnect to the wireless network.

7. Check the Network Name for Duplicates

Often the authentication problem occurs when the username and password of the wireless network do not match. You might be confident of entering the right password, but the chances are that you are connecting to the wrong network with a similar name.

If you are connecting to some other wireless network by mistake, you will definitely experience this error. The only solution for this is to change the network name (if you are on the home wireless network) to avoid any confusion. Now check if your device is able to connect to the wireless network.

These are the top solutions for solving the authentication problem. After trying the above methods, we hope your device successfully got connected to the desired wireless network. You need to follow the steps carefully in order to solve this problem or you can give a try on Fixppo for Android . The authentication error can occur at any time, but now you know what to do when it occurs in the future.

1. Restart your device

The first thing you should try if you are receiving the authentication error is to restart your device. Most of the time this will solve a lot of issues on your phone.

2. Turn airplane mode on and off

Another reliable way to clear the cause of authentication errors is to turn the airplane mode on your phone on and off.

Find airplane mode in the connections settings. Tap it to turn it on and then again to turn it off.

3. Reset the network

1. Open the Settings on the device and select Wi-Fi.

2. Choose the network you want to connect to. Locate the setting to “Forget the network.” This will erase data about the network on your phone.

3. Go back to your Wi-Fi settings and select the same network again. Enter the password and let it connect to the network.

4. Reset network settings

Nearly every network issue can be fixed by resetting the network settings on your phone.

1. Open the Settings and locate “Reset network settings.”

2. Tap “Reset Settings,” and when asked, confirm the reset. All Wi-Fi, mobile data, and Bluetooth settings will revert to factory settings.

Any errors should resolve, and you can then connect to the network.

5. Check maximum devices supported

There may already be too many devices already connected to the network, which prevents you from connecting. If you have access to the router, you can open your router’s settings and note the connected devices. Disable a few of the devices and try to connect again.

6. Restart the router

It might be the router that is having issues. Restart the router by switching it off for 30 seconds and then on again. Try to connect your phone to the network again once the router is up.

7. Change from DHCP to static

The default IP address assignment on your device may be set to DHCP. If so, it could be causing the authentication error. Changing this to static could be a solution.

1. On any Windows computer click the Start menu.

2. Type cmd and open the command prompt.

3. In the command prompt, type the command ipconfig/all and press Enter. You will see a lot of information, but you only need to focus on the Default Gateway, the IPv4 address, and the DNS Servers.

4. Write down the values you see for the Gateway and DNS server. You will need to ping the network to find an available IP address on your network.

5. To ping the IP address, open PowerShell and type ping followed by the address you want to test starting with the router IP address and working your way up. This will look like:

6. If the system displays a ping time, there’s already a device on the network with that IP address. But, if the response reads “Destination host unreachable,” it means the IP address is available, and you can use it to connect your device to Wi-Fi. Write down the value you find.

Input those values into your Android device by opening Settings and locating your Wi-Fi settings.

1. Tap and hold the network you want to connect to.

2. Select Advanced.

3. Change the setting from DHCP to static.

4. Enter the information you find as follows:

• IP Address : the open IP address you discovered using the Ping command.
• Gateway : the Default Gateway IP address.
• DNS 1 and DNS 2 : type the IP addresses of the DNS servers.

Leave any other fields in this form set as the default, then tap Save.

8. Factory reset device

If none of these ideas work on your phone, the last resort is to reset your phone back to factory settings. Locate the factory data reset on your phone and scroll down to locate the button.

When you tap the button, all the data, apps, and settings will be deleted, eliminating whatever is causing the phone to be unable to connect. This is a drastic last step, so you may want to back up your device before doing this.

Which of the above methods work to fix Wi-Fi authentication errors for you? If you are sharing your Wi-Fi network with your friends, you can easily do it with a QR code and not have to reveal your password. Alternatively, you may want to prevent the Wi-Fi from automatically turning on to save battery.

WiFi Authentication Errors and Methods to Solve Them

You attempt to connect to a WiFi server you've used before, but you can't get logged on. Instead, your phone tells you an authentication error has occurred. 

The majority of us ( about 97 percent ) own cell phones. But many of us feel baffled when the devices in our pockets won't do what we expect. If you’re dealing with an authentication error, know this: You can solve the problem. But before you do, ask yourself if the connection is secure and worth fighting for.

What is a WiFi authentication error?

Sometimes your phone will not connect to the internet with a WiFi account you've used before. This is an authentication error, and unfortunately, these problems are relatively common.

Close to 70 percent of us use our own devices while we're at work, and we might tap into the company WiFi to get the job done. But at the same time, about 30 percent of us say that we can't get our work done because the cell connection isn't stable, strong, or both. 

A WiFi authentication error could be to blame. This problem is often caused by:

• Airplane mode. You’ve traveled recently, and you’ve ensured your phone won’t connect while you’re in flight. Many devices allow you to turn WiFi back on even while in airplane mode, but the standard airplane mode settings will turn it off. 
• Poor connectivity. Your WiFi router is far away or overloaded, so you can’t push your way in. 
• Software updates. You’ve made changes to keep your device secure, but they are interfering with your WiFi connection. 

This is just a sample list of what might cause a WiFi authentication error. There are many more. 

How to fix a WiFi authentication problem

Your phone includes several handy options that can help you get online with ease. But use them carefully.

If you're struggling to connect with a public WiFi account (such as one you might use at a local coffee shop or in the airport), take stock. Hackers can take over these accounts and steal your data . Many experts recommend you do not connect to public WiFi at all. Before you fight to reconnect, ask yourself if it’s worthwhile. Can you use a VPN instead? Or can you wait until you're close to a trusted WiFi signal?

If you trust the WiFi account and you want to get connected, try these six steps:

• Forget the network. Head to WiFi settings on your device, find the network you're trying to connect to, and tap "forget." 
• Check your password. Head to WiFi settings on your device, find the network you're trying to connect to, and tap "forget." Find it again, and retype your password. 
• Refresh your device. Tap the notification bar on your phone, and look for "Airplane Mode." Turn it on for a few minutes, and turn it back off. 
• Change your network from DHCP to Static. Head to WiFi settings on your device, find the network you're trying to connect to, and tap "Manage network settings." Change the IP settings you see there from DHCP to Static.

This error is common in certain Android smartphones and can easily be fixed.

Here are some of the best fixes for “WiFi Authentication Error” on Android smartphones.

Some of the most common reasons behind this error are,

• Poor Network
• Incorrect Password
• Corrupt Network Settings
• Too many devices are connected to wifi
• Frequency Band mismatch
• Fault or Glitch in Phone Network Hardware
• IP Address mismatch

How to Fix Wi-Fi Authentication Error On Android

1. reset the wifi network.

The first possible fix for the WiFi authentication error is to reset the connection between the router and the Android smartphone. In addition to the authentication error, this fix also resolves many other network-related issues.

To reset the WiFi network follow these simple steps,

• Open WiFi under Network Connections from the Settings of your smartphone.
• Locate the WiFi network you are trying to connect to and then long-press on it.
• Press the Forget Network option and re-enter the WiFi password .

If everything goes well the WiFi authentication error won’t appear now.

2. Restart The Router

As you might know, most electronic devices start working correctly when restarted.

Consequently, restarting the WiFi router can fix the WiFi authentication problem instantly.

Once you turn off your wireless router wait for a few minutes before restarting it.

3. Turn On/Off Airplane Mode

Sometimes, the phone’s mobile network becomes an interference while connecting to a WiFi network.

As a result, turning on/off Airplane Mode might resolve the authentication error on your Android device.

When turned on the Airplane Mode suspends the device’s radio-frequency signal transmission technologies, effectively disabling all voice, text, and phone services.

4. Reset Network Settings

The next easiest solution for solving WiFi authentication on Android smartphones is to reset the network settings. You can effortlessly reset network settings on your Android tablet by following these simple steps.

• Locate Reset Network Settings from the Settings of your smartphone.
• Tap on Reset Settings.

Once the process is completed the WiFi, Mobile Data, and Bluetooth network settings of your smartphone will reset.

5. Check The Number Of Supported Devices

As mentioned earlier, there’s a limit as to how many devices can connect to a WiFi network.

If your WiFi network has reached that limit then disconnecting the inactive devices from the WiFi network might resolve the WiFi authentication problem.

6. Check The WiFi Network Name For Duplicates

One of the primary reasons behind the occurrence of the WiFi authentication error is an incorrect username and password.

If you are confident that the password entered by you is correct then you might be connecting to a different network with a similar name.

In order to prevent this error assign a unique name to your WiFi network. Once fixed, your device will connect to the wireless network flawlessly.

7. Verify Network Security Type

Another simple problem that might cause WiFi connectivity issues is the type of network security that has been applied to your WiFi network.

If you have access to the username and password of your WiFi router, you can simply change the network security type.

If the security protocol is WPA simply change it to WPA2 and vice versa.

8. Modify Wireless Network Configuration

If any of the simple solutions didn’t work for you then you can resolve the WiFi authentication error by changing the wireless network configuration settings from DHCP to Static IP. Generally, DHCP is the default setting.

In order to make these changes follow these simple steps.

• Choose Modify Network and check the Show Advanced Settings box to change the network from DHCP to Static.
• Next up, note down the information showed in the IP address field below. 
• Lastly, re-enter the same information and simply save it.

If you think that the above-mentioned fix is a bit difficult for you to understand then you can simply contact your ISP and ask them to modify wireless network configuration for you.

9. WPS Push Button

Wi-Fi Protected Setup is not exactly a way to fix authentication problems. That said, you can use this method as an alternative way to connect to a WiFi network.

• Locate WPS options from the Settings of your smartphone.
• Tap on a WPS Push-button on your smartphone and do the same on your router.

In a matter of a few minutes, a secure network connection will establish between your smartphone and the wireless router.

It is worth noting that, once you factory reset your device all of your data will be permanently deleted. Consequently, we advise our readers to keep a backup of important files and contacts before resetting their smartphones.

In order to reset your smartphone, head on to Settings > Backup & reset > Factory data reset.

12. Contact Your Smartphone Service Center

5 ways to fix Wi-Fi authentication problems on an Android when your device won’t connect to the internet

• A quick fix to Wi-Fi authentication problems on Android is to toggle airplane mode on and off, or “forget” the Wi-Fi network and reconnect to it. 
• You might sometimes encounter an authentication error while trying to connect to Wi-Fi with your Android device even if it’s a network you have used before and your password is correct. 
• Here are the most common ways to fix Wi-Fi authentication problems on an Android device.
• Visit Business Insider’s Tech Reference library for more stories .

Occasionally, you might have trouble connecting to a Wi-Fi network even though it’s a network you routinely use and all your settings should be correct, including the password. This Wi-Fi authentication error is frustrating because it’s not always clear why it’s happening. 

How to fix Wi-Fi authentication problems on Android

The next time a Wi-Fi authentication issue happens to you, here are the most common ways to troubleshoot and solve the error. 

Toggle Airplane mode

As with all kinds of troubleshooting, you should start with the easiest possible solutions and, if they don’t work, make your way through progressively more complex solutions. The easiest thing you can try is to put your Android phone in airplane mode, which disables most or all of the radios on your device. It’s akin to rebooting your Wi-Fi radio.

To do that, swipe down from the top of your phone to see the quick access icons, and tap “Airplane mode.” (The icon will be shaped like an airplane.) Wait several seconds and tap the icon a second time to turn it off. Check your Wi-Fi and see if it now connects properly. 

Forget and reconnect to the Wi-Fi network

If the Wi-Fi settings for this network have become corrupted, you might be able to get up and running by “forgetting” the network and then reconnecting to it. You’ll need to know the Wi-Fi password before you begin. 

1. Start the Settings app.

2. Go to your Wi-Fi settings. Where to find this depends on which Android phone and OS version you are using, but generally it will be found in "Wireless & networks" or "Connections."

3. Tap and hold the Wi-Fi network you are trying to connect to or tap the gear-shaped settings icon. Then choose "Forget this network."

4. After a moment, the network will appear in the list of available networks. Tap it and enter the password to reconnect. 

Reboot your Wi-Fi router

If you are unsuccessful in trying to connect to your own home Wi-Fi network, you have another option: You can reboot the router. Simply unplug the router and leave it unpowered for about two minutes. Then plug it back in again and check your connection. 

Change the network from DHCP to Static

If you still can't authenticate, you can try forcing your Android phone to use a static IP address instead of dynamically choosing one when you connect, which is the default and much more common. 

1. Open your Wi-Fi settings in the Settings app, like you did when forgetting the network, tap and hold the network or choose the settings icon.

2. Choose "Modify this network" or "Advanced" depending upon your Android phone and look for "DHCP." 

3. Tap "DHCP" and, in the dropdown menu, choose "Static."

4. Tap "Save."

Now that your phone is using a static IP address to reach your Wi-Fi network, try again. 

Reset your network settings

If none of those options work, you have one last option: You can try to reset all your network settings. 

1. Start the Settings app. 

2 . In the search box at the top of the Settings page, type "Reset." In the search results, find and tap "Reset network settings." This will wipe out all your Wi-Fi, cellular, and Bluetooth settings, so you will need to reconfigure those networks.

3. Tap "Reset network."

Android: How to Fix Wi-Fi Authentication Error

Just the other day I tried use my Android to connect to a Wi-Fi network I’ve connected to before, but couldn’t. I had to introduce the password again since I did a factory reset on my device a while back. After typing in the password and seeing that my phone was trying to connect, the only thing I saw was an “Authentication error”.

I checked that I was connecting to the right network and made sure I was typing in the correct password. Still, that dreadful message appeared. Has this happened to you too? Here are some tips you can try to get rid of the problem and reconnect.

• 1 Try Airplane Mode
• 2 Try Resetting The Wi-Fi Connection
• 3 Change the Wireless Network
• 4 Refresh All Your Network Settings
• 5 Conclusion

Try Airplane Mode

What happens when you enable Airplane Mode is that all radio-frequency signal transmission on your phone is turned off. You can use Bluetooth, WiFi, or even make a phone call.

This is a useful tip because sometimes your phone’s mobile network interferes with your phone trying to connect to a network.

To give the airplane mode a try, swipe down from the top of your display and turn off the mobile network and WiFi. Now, enable airplane mode and without turning this last feature off, go ahead and turn on the WiFi option.

If your phone connects to the WiFi network without any issues, then you can turn airplane mode off. Turn on Wifi and mobile network, and everything should be OK now.

Try Resetting The Wi-Fi Connection

Sometimes the answer lies in starting over, and that’s why resetting the WiFi connection could be the answer to your problems. Eliminating the wireless connection and then try to find/ connect to it again. This is a solution that has worked for many, and hopefully, it will work for you.

Go to your device’s Settings and tap on WiFi. Find the network you’re having trouble connecting to under WiFi Networks. Long-press on the network, either the SSID or name and you should see a small window with the options to either forget the network or modify network config.

Tap on the Forget Network option and distance yourself from the router until you’re only getting one bar signal. Once you have that one bar, connect to the network once again.

Change the Wireless Network

Another reason why you’re having this authentication problem is that of an IP conflict. If that’s your case, then the best thing you can do is change the wireless network setting from DHCP (default) to Static IP.

You can quickly do this by going to Settings and once again going into the WiFi option. Long-press on the network until you see the same window as before, but this time tap on modify network config.

Tap on the advanced options box and look for the option that says DHCP. When you tap on it, there is only going to be one other option that should be the Static option. Select it, and then you should see an IP address field.

When it appears, save the information you see in the static IP address field and erase it. Type in the same data again and tap on save. Only add the information if you’re sure it’s the correct one. If you have any doubts, it’s best that you call your ISP (Internet Service Provider).

Refresh All Your Network Settings

If the previous options have failed, then it looks like you have no choice but to refresh everything. By everything, I mean Bluetooth, mobile network, and wireless network simultaneously.

To do this go to Settings > Backup & reset > Network reset and tap on Reset Settings. The process shouldn’t take too long, but when it finishes, try to log onto the network that’s giving your problems and hopefully, you can connect.

Don’t worry about losing any important data since you won’t. This will though, wipe the data from all the connections you’ve ever made.

There are times when you might never know what caused this problem, but here you have the solution to get rid of it. Hopefully, you authentication error doesn’t require calling a tech guy.

Did I miss a method that you use to fix this problem? If so, share your thoughts in the comments, so others can benefit as well.

I think my router is blocked by wifi owner ,how can I unblock it .please help me

A storm knocked out my inner connection with my carrier. A reset reset at our substation (I love out in the country) and when the tech arrived and tested at my home he seemed confused. Then I e,plaines that there needs to be a reset at the substation, he drove up the road, found what needed to be reset, and my service was restored. All of my Wi-Fi gear in my home was working again. 2TVs, my computer and my tablet. Everything except my Samsung Galaxy S8+. When I attempt to get the Wi-Fi on this device, it’s now requiring the Wi-Fi password. I put the correct OR in and my ST S8+ says it’s incorrect. I followed all of the above ‘fixes’ but to no avail. I don’t want to do a hard reset, I did the “reset network settings” noted above and that didn’t work either… Any suggestions?

Thank you in advance, Exasperated in the Boondocks

I tried all this and it did not work for me. My issue is little different. My wifi worked with no issues stayed connected. I was renting a modem from my isp I bought a netgear modem router combo . Kept the same network name and password, my phone and my wife’s phone will connect but will drop and say “incorrect password”. We sent the new modem back and got different brand did same thing sent that back and went back to the netgear does something. We kept the same network name and password so all the devices could connect but our phones and one pc keeps dropping wifi with incorrect password. So frustrating..

Thank you. It fixed my authentication problem in no time. Keep up the good work.????

Hello everyone, first of all thanks so much for this convenient way. I was totally exhausted due to that error and finally find the way thanks to u all ????????.

What eventually worked for me was to connect to a hotspot from another mobile. It connected to the hotspot straight away. After that it connected to my wifi network with no problem

Hi had this problem and none of those methods worked. What worked for me was changing the MAC address type to Phone MAC and it worked straight away. Hope this helps!

Hi my problem is that my son put wrong details into my samsumg galaxy A11! I want to put right details but the phone won’t allow it I tried reset network things like that it won’t allow any thing I don’t know what to do how can I put the right details in it. Also it says put identification details, ca certificate all that I’m in a mess? Can somebody tell me what to do! But the phone works in other places just not in my house I feel sad.

Thanks for the help. I tried everything you suggested, but nothing has worked. Not sure what to do now

James Grieve You sure as f#*k took the long way around with that essay of yours!!!… a single paragraph would have been more than enough to make your point with room left over for a few entertaining sentences of you not trying so hard!… ????????

After few days of finding, finally I manage to closed my case of Authentication problem with wifi trying to connect to Android mobile hotspot. It was found that my Huawei mobile hotspot has blacklisted my other fon trying to connect. After release it from blocklist.. I can connect without any issue.

Hey everybody, I just wanted to put this out there, as it took me 12 very painful and frustrating weeks to get to the point where I finally understood the problem with: Authentication Error / Could Not Authenticate Connection / Couldn’t Authenticate Connection……….. I went around and around in endless, tiresome, repeating, ever decreasing circles for 3 months and, in that time, piece-by-piece, I completely replaced the entire system: PC / MiFi / Mobile Phone / Alexa / Smart-Plugs / Smart-Lights / Factory-Resets abound on everything here-there-and everywhere, plus all of the good advice on Airplane Mode / Forget Network / Static IP / Reset Wi-Fi / Etc / Etc / Etc / Etc……….. All to no avail…..!!!! Everything Failed…….!!!! Nothing Worked…….!!!! The flowers in my garden grew down. Their colour was pain. Their fragrance was sorrow. Into my eyes grew their roots feeling for tears to nourish the black hopeless rose within me. When, finally, the Eureka: I have found it! Moment finally, finally arrived, it was an instant relief, revelation and success……… Now, everything works, and it is SO wonderful, and SO simple…..!!!!! So here it is: I do hope that you have bore with me thus-far because HERE IS THE ANSWER!!!!!!! …….. If you are using a Mi-Fi / MiFi as your internet access point, and you have a: Smart-Home / SmartHome / Alexa / Smart-Plugs / SmartPlugs / Smart-Light / SmartLight / Arrangement………. MiFi / Mi-Fi only supports 10 devices – There it is in a nutshell! N.B. That is only a maximum of 8 Smart Devices + Alexa + Mobile Phone. So, when it came the moment to setup and connect device 11, my whole world fell apart and the garden got sad and miserable. (I SO! wish I knew this in December!). Some MiFi’s claim to handle 15 connected devices, some only 8 (may be true – check your MiFi Device!). My Huawei E5573 does 10 Max! [Remember to leave 2 slots available for Alexa and Mobile Phone!!]. So, I reconfigured my Smart-Home with 8 connected Smart Devices (+ Alexa + Mobile Phone). Simple. Logical limit understood and catered for. Everything works great!!!!!!! Sing Hosanna. Glory be to God. The flowers in my garden grew up. Their colour was comfort. Their fragrance was happiness. Into my heart grew confidence of feeling for the future of 21st Century Technology to nourish the beautiful rose within me. If my little post here saves you 12 minutes of the 12 weeks of pain and frustration that I have suffered, then I give this time to you as a gift! TECHNOLOGY / COMMUNICATION MANUFACTURERS COME ON! YOU NEED TO BE DOING A BETTER TECHNOLOGY / COMMINICATION JOB HERE!

Thanks for the ideas’s I was having this error on ALL Phones… while wiired Computer was working. I tried all the above ideas, but what work was: Changing the Wifi password to something new.

Thanks mate. The airplane tip did it ! I previously had the issue almost every time the phone went back from sleep mode. My phone is a BlackView 7000 Pro with Android 7.

Hello, I’m trying to connect to a Wi-Fi network from my school but it keeps on saying Couldn’t authenticate connection. What does that mean? Also, my T-Mobile service isn’t working either, I don’t even know what’s wrong. Can you tell me what to do about the solution about making the wi-fi network available on my Samsung Galaxy S9 again? Also, I reset my network settings because I wanted to fix the problem but it still not working. The wi-fi works on my computer not my phone and I’m so devastated. I need to fix the issue. What advices do you have for me? I’m not resetting my phone because it has all my contacts, photos, songs and everything I love. I need a solution to make the network work on my phone again. The T-Mobile service line isn’t working at all for me, could you tell me how to fix that? I need to have answers about this mess. All of my wifi-networks, bluetooth network are gone because I accidentally reset the settings for those. Can you please tell me how to fix them? Thank you very much!

Is this options is applicable in every devices,like tablets and Ipads?

Did all the above. All other devices in my home work on both routers. I just got the phone did all the set up used it for a day and received a notification that I had a Samsung update and it hasn’t worked since. Did the system reset and tried to set the phone up again but still will not connect. Still getting authentication error.

My partners phone wont connect to his wifi at home without using his mums phones bluetooth ive tried all of these things and they arent worming would someone be able to help me

My Android TV-Box has no option to set an static IP . According to manual “Advanced option” allows for setting a static IP, subnet, gateway and DNS server. But I see just a “limited/unlimited connection” option. Nothing else!

Airplane mode helped, will try the reset. Thank you!

I appreciate the concise instructions. I happened to start on option 2 (Reset Wi-Fi connection but couldn’t get my signal strength to go down to one bar so moved on to option 3 (Change wireless connection). Was not quite thru with option 3 instructions when the Wi-Fi connected! My biggest problem was I forgot my MAC Wi-Fi password which is required in all the options. It wasn’t posted on my router (I must have changed it in the past.) I took a wild guess and that did the trick during option 3 . Tatoo your Wi-Fi password on your forehead so you don’t forget it! Thanks again.

Thank you for this article, it helped with airplane mode. :)

My issue was 2 routers. I have DSL. That is my wired internet signal. I then take the output of the lan router and send that into my 300BPS Wifi router. Always keep your instruction booklet or at the minimum the network setup CD. Remember, even if you cant get online, you can still use your browser, I use Chrome , an type in your modems access number I.e. https:// 197.543.6.8 this will take you to your modem setting front door. You will be asked for password. Forgot? Look under the modem. In tiny print the default password will be admin. Same for user. Once here you can 1. Change your security password (although it still reverts to admin) or 2. Run the basic network setup CD. With that you be back up and running. It works with lan = wired to computer. It also works with wifi. Remember as long as there is a tether to your internet you can get into your wifi router front door page too using the specific http:// address. One point to remember if using more than one router you will need to remember to http router address. Try not to mix them up.

And at the end of all this I noticed that the problem lies with Cell phone manufacturer or service provider. Thought I didnt have wifi got an error. Created a wifi network on the PS 4 gaming console and it accepted it. But my cell- dont have a data plan, would not work.

I had all problems above, and tried all the steps you recommended. I then tried Auto reconnect. It solved the issue. My phone is working ok now. I hope this helps you.

Thanks so much, I had been trying all night to fix this matter. Had one more go this morning with your suggestions and it worked using Setting the Network Connections. Very pleased!

Disable the auto protect, then once connected switch it back on. Must be a problem with auto protect handshake with wifi

my issue started after my provider had me do a network reset on my phone. they said i would need to reset my wifi after the reset. i could not get it to reset my wifi. i kept getting “authentication error” with every attempt at reconnecting it. on the phone for an hr with provider before being told my sim card was broken. i decided to head out to comcasts store, my cell and internet provider, after work to see if that really was the issue. however while at work i was able to connect to my works internet i obviously this was not the case. while at home all my other wifi devices were connected so it didn’t seem like it was my router. i had even reset it hoping my cell would pick it up prior to calling my provider and nothing different. after realizing it had to be my router and cell not communicating correctly i went back to check out my router and found a small square button on the top labeled “WPS”. did some googling and saw this was a way to connect your phone to the wifi, pushed that magic button and it instantly reconnected with no issue since.

Same here Authentication error on my 2g wifi network. The only thing that had changed was I’m rolling out lots of IP switches for lights appliances smart home stuff all of which only operate on 2G wifi . Any of the people that have commented so far been playing with smart home gear? Maybe my router on the way out all other devices connect ok. The alexa devices do to drop out occasionally but reconnect after a few hours

Or did you get a fix ?

Ive tried everything on my samsung galaxy s10e This is not the first time with samsung that i have had a connection issue with my wifi and receieve the authentication error message. I have had the same issue as “Appleton” before where it will connect for just a few minutes then disconnect for days. My wifi is connecting fine with my computer and smart TV but for the love of god will not connect to my phone! Please someone help me fix this!!!

I tried all the options that you gave but still the same error…please help me please

I too tried all the steps and the error remains. Is it possible that the phone itself may have a fault? If I connect today for an hour, then I don’t connect till days later for about an hour. Frustrating.

Nothing has worked for me. Still have the same issue.

I tried all the options one by one including data reset. but authentication problem remains but now i get the welcome – start- ( an unauthorized attempt has been made to reset you device to factory default settings)- OK – WiFi- (authentication error occurred) -it will not let me go no further, i cant get to any apps or setting button, at the top right corner is battery % rectangle with an airplane. i have watch all videos tried everything but now i cant get to any thing HELP ME PLEASE!!! I csn’t get pass the Connect to Wi-Fi screen and all my screen apps disappeared.

The flight mode option worked for me… Thanks so much!

I tried all these, including resetting all network connections, and still getting the authentication Error message.

Any other ideas?

I tried all the options one by one including data reset. but authentication problem remains but now i get the welcome – start- ( an unauthorized attempt has been made to reset you device to factory default settings)- OK – WiFi- (authentication error occurred) -it will not let me go no further, i cant get to any apps or setting button, at the top right corner is battery % rectangle with an airplane. i have watch all videos tried everything but now i cant get to any thing HELP ME PLEASE!!!

I did the Airplane mode and so far the WIFI is staying connected. Keeping fingers crossed that it will remain connected. Thanks a bunch!

Step one worked for me (enabling airplane mode). Thanks a lot :-)

Thanks, it helped!

Thanks I tried 1 no worky but going down to 1 bar then doing the long hold etc. did but only on the 2nd try. I figure I did something wrong in the steps the first time since it worked 2nd time. I think it was because I did not turn airplane mode back ON before beginning the second method. But, it’s all good now. I have a Motorola phone which is really pretty good for the money but it never happened with my Samsung. Anyway, I owe you a thank you!

Even i tried all of the steps there is still authentication error. I hope you can help me, I badly need to connect to our wifi as soon as possible.

Thank you! Thank you! I did the airplane mode and it didn’t work and I did Method 2 and it didn’t work and I was about to do Method 3 when suddenly wifi was connected! Have a Merry Christmas and a Happy New Year.

Still have the issue after each step was tried. And I don’t think it’s my ISP either because i have 2 networks and the other is still properly connecting. The problem is the other network has a much weaker signal and tends to drop.

I just got back from an international trip I was unable to use my phone in Japan, Singapore and Kashmir. However I used the local wifi service to communicate with my family here in USA. But when I got back home last week ever since I am unable to use my home wifi service. I tried to restart my phone as well as my home network router but I don’t get any internet connection. Any solution will be appreciated. Thanks

I only have this problem with my Comcast/Infinity supplied wifi.

Airplane mode fixed my issue, Thank you :)

DD chhaya i also still hAVE THIS STUPID PROBLEM

I should also include; for me, a restart of the phone revolves the issue temporarily, but it eventually resurfaces.

I managed to solve my problem using method no. 2. – Tap on the “Forget Network”. distance myself from the router and turn on the WIFI. TQVM! :)

I tried all the options one by one including data reset. but authentication problem remains

Are you tired of constantly struggling with Wi-Fi authentication problems on your Android device? Do you often find yourself unable to connect to your Wi-Fi network? This can be frustrating, especially when you have important work to do or need to access the internet for entertainment purposes. In this article, we’ll take a look at some of the most effective ways to fix Wi-Fi authentication problems on Android.

• Restart Your Device:

The first step in solving this problem is to restart your device. This can often resolve the issue with the authentication process. Simply press and hold the power button on your phone and tap ‘Restart’ to reboot your device. After restarting, try connecting to your Wi-Fi network again.

• Forget Wi-Fi Network:

If restarting doesn’t help, the next step is to forget the Wi-Fi network you’re trying to connect to. Simply go to your phone settings, Wi-Fi, and long-press the network you want to forget. Tap ‘Forget Network’ and then try to connect to the Wi-Fi network again. You will need to enter the password again.

• Check Your Wi-Fi Password:

Sometimes, the authentication problem is due to an incorrect password. Make sure to double-check the password you are entering to ensure it matches the password of your Wi-Fi network. Remember, passwords are case-sensitive, so even a minor mistake can cause authentication issues.

• Disable MAC Filtering:

If you have enabled MAC filtering on your router, it can prevent your Android device from connecting to the network. Disable MAC filtering and try connecting to your Wi-Fi network again. After connecting, re-enable the MAC filtering to ensure security.

• Restart Your Router:

If none of the above steps have worked, try restarting the router. Unplug the router from the power source and wait for 30 seconds or longer before plugging it back in. Wait until the router comes back online and then try to connect your Android device to the Wi-Fi network again.

• Reset Network Settings:

If none of the above methods have worked, resetting your network settings may be the solution. This will remove all Wi-Fi passwords, Bluetooth connections, and VPN settings from your device. Simply go to your Android settings, tap on ‘System’, then ‘Reset options’, and finally ‘Reset Wi-Fi, mobile & Bluetooth’. Once complete, connect to your Wi-Fi network again.

In conclusion, Wi-Fi authentication problems on Android devices can be frustrating, but with the above steps, you can resolve the issue in most cases. Start with a restart or forget network, check your password or disable MAC filtering, and if all else fails, try restarting the router or resetting network settings. By doing this, you can connect your Android device to your Wi-Fi network and enjoy uninterrupted internet connectivity.

Why does a WiFi authentication error happen?

The WiFi authentication error occurs when your android phone cannot successfully connect to a WiFi network when you want to connect even if you’re using the correct password or sometimes if you are on airplane mode. Under normal circumstances, your phone will automatically connect to the wireless network if you’ve already connected to the WiFi network before. You may encounter issues if you have an unstable signal, which you can improve by using cell phone signal boosters .

If you have accidentally enabled the Airplane mode in your network settings, then your phone will not connect to any network on your android devices. But sometimes, the authentication problem is more than your phone is in airplane mode. The following are some of the common reasons why you get a Wifi authentication error:

• Recent device update
• Router malfunction
• Unstable network connection
• The number of users that can use the WiFi network is limited

There are simple methods to fix the WiFi authentication problem. The right solution depends on what caused the error to occur. The following are some of the common solutions and ways to fix the error which you can easily try.

You can do this by forgetting the network (name (the one you’re having problems connecting with) on your android device before you try connecting again. Here are the steps to do it.

Step 1: Go to Wifi Option in Settings Menu

Go to  Settings on your phone and look for “ Wireless & networks .” Some smartphones instead have “ Connections .” Tap this and go to the WiFi option.

Step 2: Find the Network You’re Having Issues With

Once you click the WiFi option on your network settings, you will see a list of nearby WiFi networks, including the ones you’ve already connected to before. Tap on the network name you’re having issues connecting with.

Step 3: Tap “Forget Network”

When you choose the network, you’ll see a “ Forget network ” option on your network settings. Tap this to reset the settings of the network selected. Once reset, try to enter the password by connecting to the network. You’ll be asked for the authentication password. Just type in the password and connect.

If this step didn’t fix your WiFi authentication error on android , move on to the next one.

2. Change The Wireless Network From DHCP to Static

Step 1: go to wifi options in settings.

Go to your WiFi settings on your android device and look for the connection you’ll change.

Step 2: Tap The Network Which You’re Connected To

There will be a list of the nearby WiFi networks. Just choose and press the wireless network you’re having issues with (or the one you want to connect to) and try to connect.

Step 3: Modify The Network

When you press the wireless network, you will either see a  Modify  or  Manage network option. Tap it.

Step 4: Change The Network To “Static”

In the WiFi settings, you’ll see an “ Advanced Settings ” option on your android device. Choose this option and look for “ IP Settings .” From there, change the IP from DHCP to Static. Finally, enter the IP address (the one found at the back of the router) in the field. Save the settings, then reconnect. This fixes the WiFi authentication error for most people; if this fix doesn’t work for you, try out the other steps.

3. Restart The Router

If the first 3 methods didn’t fix your WiFi authentication error, the issue might be due to the router itself. Restarting the router might do the trick and restore the internet connection. There are 3 ways to restart your router, depending on the type of router you’re using. They are as follows:

Step 1: Disconnect The Power Cable

For regular routers, the best and common way to restart it is to disconnect the power cable. Doing this will turn the router off. Wait for a few minutes before reconnecting the power cable and turning on the router again.

Step 2: Restart Using The Power Button Or Warm Reboot

However, if you are using a wall-mounted router, then there’s another way of restarting it. Since it’s hard to access disconnect the power cable, you can instead push the power button to turn the router off. You can also use the warm reboot to automatically reset the connection.

Step 3: Adjust The Allowed Connections

If there is an internet connection but you can’t still connect, it may be because many users are already connected to the router, and you have reached the maximum allowed connections. Just simply adjust the maximum number and restart the router.

After restarting the router, restart your device and see if you’ll still encounter the WiFi authentication error. If the error still

4. Reset Factory Settings

If the first 3 methods fail, or if your phone suffers from other random errors aside from WiFi authentication errors, then your phone might have software issues. This happens when you install a firmware update, custom ROM, or a faulty application.

Note : Before anything else, I recommend that you clear the app cache of any recent apps you’ve downloaded, especially if you gave the app permission to access your network before you do factory reset.

The best way to solve software issues and reset settings is to reset your phone to factory settings. Although at the cost of deleting all of your data. Just make sure that you’ve backed up your data. The best way to do this is to backup your phone first to the cloud . Once you have done this, you can then reset your device settings. Just follow the steps below.

Step 1: Go to “Backup & reset”

Go to settings and then just scroll down to find the “ Backup & Reset ” option. Tap it to open.

Step 2: Turn On Automatic Restore

You’ll see the  Automatic Restore option. If it’s not turned on, make sure that you turn it on.

Step 3: Reset Factory Data

Find the “ Factory Data Reset ” option and tap it. Then tap the “ Reset Phone ” button to confirm the action. The process will take a few minutes. This will boot your phone’s system. If the problem is indeed due to software issues, then you can connect to the network.

Unless your phone has hardware problems, this will fix your WiFi authentication error problem on your device.

5. Toggle Airplane Mode

As with all kinds of troubleshooting, you should start with the easiest possible solutions and, if they don’t work, make your way through progressively more complex solutions. The easiest thing you can try is to put your Android phone in airplane mode, which disables most or all of the radios on your device. It’s akin to rebooting your Wi-Fi radio.

Follow these steps to put your android phone in airplane mode,

Step 1: Swipe down from the top of your phone 

Step 2: You can see the quick access icons.

Step 3: In those icons, tap “Airplane mode.” (The icon will be shaped like an airplane.) 

Step 4: Wait several seconds and tap the icon a second time to turn it off. Check your Wi-Fi and see if it now connects properly.

Can’t connect to 5 Ghz WiFi?

Another common issue users face is that they can’t connect to 5 Ghz WiFi. Let me tell you, to be able to connect to 5 Ghz bandwidth, your phone should support it in the first place.

To check it, press and hold the WiFi icon in the notification tray or go to Settings > WiFi > Advanced > Frequency band and check which band is enabled – 2.4 Ghz, or 5 Ghz, or automatic. If your phone doesn’t support 5 Ghz, it won’t show in the frequency bands. To enable 5 Ghz frequency, select the 5 Ghz frequency band.

Note that, 2.4 Ghz connects across a long-range but the speed is low whereas the 5 Ghz band provides faster speeds but for a shorter range.

I get a authentification problem

I connect to wifi but then it tries to reconnect almost immediately and I receive a authentication problem and it won't connect. Help!

Is this a good question?

I have the best solution. Don't buy Amazon fire/kindle fire ever again. This was my wisest solution after purchasing this trash a few months ago.

They are sub-par in every meaning of the phrase. I have an old Roku player 3 and even older western digital media player that doesn't have this authentication issue, yet the best solution is to restart your router. Why isn't this happening ot other devices? Because they are not useless brands. A brand new Amazon Fire tablet has more errors than there are words in a George R. R. Martin Novel. Not to mention one of the worst AI's in human history, Alexa, who is basically borderlining the invasive stupidity of Cortana from Microsoft. Do yourself a favor, and educate Amazon at the same time, and don't purchase garbage allowing lesser brands to flood the markets.

Are you entering the correct password for the WiFi network that you are trying to connect to?

Is it trying to connect to the same WiFi network every time?

Try the 'forget this network' option on the one that you wish to connect to, restart your Kindle, go to connect to Wifi network and select the network you want. You will need to know the password.

Update (03/07/2016)

Hi BettyEllen,

Couple of things to try.

1. Can you connect to the Wifi network using another device, e.g. a mobile phone? This will prove that the password being used is correct.

If it connects automatically without the need of a password (because it remembers it from being used before) 'forget' the network and then try to connect to it again having to use the password.

If it connects after entering the password then at least it proves the password is correct.

If you can't connect perhaps the password may be case sensitive or you are maybe using the wrong one. If you are trying to connect to your wireless router, try switching off the router, wait for a minute then switch it back on again. Allow it to initialize and then try to connect to it.

2. Try a 'reset' on your Kindle. Press and hold the Power button for 20-30 seconds, release and let the Kindle start. Try to connect to the WiFi network.

blocking your kids access can sometimes do a reset and block all new devices. If this happens and you didnt activate a home router admin login, reset your router, clear your cache from problematic devices using mobile networks plus restart your device. netgear: allow all new devices buton linksys: use admin right box to create a new password if youre locked out. Wifi password is different from router admin password. wifi allows guests who knows the password on back of router, router admin controls users or intruders.

To fix this issue please ensure your router's WPA settings are not above WPA2.

WPA stands for wifi protected access which helps to protect WIFI passwords from being cracked. Login to your router go to advanced settings then wireless then security. Here you will see a drop down for security. if its set to WPA-3 please change it to WPA2-PSK (Do not worry this is still a secure protocol). Apply the changes to your router.

Once the change is completed you will need to reauthenticate to the network using the password.

I believe kindles cannot support anything higher then WPA2

Please let me know if this works for you.

ixed it!!! OMG! Okay, googling lead me to an amazon page that mentioned changing my clock to the correct time zone. Well I haven’t turned this thing on in 2.5 years, it was still showing a previous time zone I lived in, and my password to my Amazon account had changed. Nothing I clicked on would let me change my password. After 3 hours I decided to try changing the clock. Well, for some STUPID reason that prompted an Amazon auth screen to pop up and let me sign in to my account with my new password. Dang thing works now. It’s downloading software updates as I type this. Good luck!

The cache and data are temporary files and settings stored by various apps and services on your tablet. Over time, these files can accumulate and potentially cause authentication issues. Here’s how you can clear the cache and data on your tablet :

1. Clear App Cache: Each app on your tablet has its own cache, which stores temporary data to improve app performance. Clearing the app cache can resolve authentication issues specific to certain apps. To clear the cache for a specific app, go to the Settings menu on your tablet, choose “Apps” or “Applications,” select the desired app, and then tap on the “Clear Cache” or “Storage” option. Confirm the action, and the cache for that app will be cleared.

2. Clear App Data: In addition to the cache, clearing the app data can also help resolve authentication problems. Clearing app data will delete all app settings and user data, so be cautious as this action may require you to sign in again and set up the app from scratch. To clear app data, follow the same steps as clearing app cache, but instead of selecting “Clear Cache,” choose “Clear Data” or “Clear Storage.”

3. Clear System Cache: Clearing the system cache can address authentication issues that may be caused by system-level processes or conflicts. The steps to clear the system cache vary depending on your tablet’s make and model, but generally involve following these instructions:

• Use the volume buttons to navigate to the “Wipe Cache Partition” or “Cache/Data Partition” option.
• Confirm the cache wipe by selecting “Yes” or “Confirm”.
• Wait for the process to complete, and your tablet will restart.

4. Restart Your Tablet: After clearing the cache and data, it’s a good practice to restart your tablet. Restarting can help apply the changes and ensure a fresh start for your device. Press and hold the power button, then select the option to restart your tablet.

Clearing the cache and data on your tablet helps to remove temporary files that may be causing authentication problems. However, keep in mind that clearing app data will reset app settings, requiring you to sign in again and set up the app if applicable. Make sure to back up any important data beforehand to avoid losing important information.

By following these steps, you can troubleshoot authentication issues on your tablet and potentially improve its overall performance. If the problem persists, or if you’re unsure about clearing cache and data for a specific app, consider reaching out to the app’s support or your device manufacturer for further assistance.

Restarting the Tablet:

Restarting your tablet is a simple yet effective troubleshooting step that can help resolve a variety of authentication problems. Restarting clears out temporary system files, closes background processes, and refreshes the device’s overall state.

1. Press and Hold the Power Button: Locate the power button on your tablet. Press and hold the button until a power menu appears on the screen. The power button is usually located on the side or top of the device, depending on the make and model.

2. Select Restart: On the power menu, select the “Restart” or “Reboot” option. This will initiate the restart process and power off your tablet. Wait for a few moments as the device shuts down.

3. Power On Your Tablet: After a brief moment, press the power button again to power on your tablet. Wait for it to boot up and reach the lock screen or home screen.

4. Test Authentication: Once your tablet has fully restarted, try accessing the app or service that was causing the authentication issue. Enter your credentials and see if the problem persists. In many cases, a simple restart can resolve authentication problems by resetting any temporary glitches or conflicts that may have been affecting the device.

If you’re still facing authentication issues after restarting your tablet, you may need to try other troubleshooting methods specific to the problem you’re encountering. However, restarting the tablet should always be the first step in your troubleshooting process as it is quick and often effective in resolving minor software-related issues.
