What Causes the Authentication Issue?

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 Problem?

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 you see it to try the easier solutions first.

1. Toggle airplane mode on and off . This 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 haven’t changed any Wi-Fi settings recently.
2. Restart your phone . Rebooting your phone is easy to do, and often fixes problems like this one.
3. “Forget” the Wi-Fi network from your phone by deleting it from the list of saved networks. To do this, openSettings >Network & internet >Internet , then tap the gear/settings icon next to the network that’s having issues. TapForget , thenreconnect your Android to Wi-Fi by entering the password.
   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.
4. Correct the date and time . The Wi-Fi authentication problem could be due to a time discrepancy between your Android and router.
5. Reset the phone’s network settings. Areset 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 (which we’ll get to later). Do this throughSettings >System >Reset options >Reset Bluetooth & Wi-Fi >Reset .
   You’ll need to try to connect to the network again after this step.
6. Troubleshoot this as a slow internet connection . Things like bandwidth overload and signal interference could be causing the authentication issue.

7. 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 is similar to restarting any tech device.
8. Check how many devices are running on the network at once . Although it’s unlikely, especially on a home network, to reach themaximum number of devices supported by the router , this could be the reason for the authentication problem.
9. If your network hardware supports it, separate the5 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 ourguide on how to change the Wi-Fi channel to see where these settings are on a typical router.
10. Change the Wi-Fi channel to fix the Wi-Fi authentication problem (see the link at the bottom of Step 8 to learn how). Choosing adifferent Wi-Fi channel number can help avoid interference , especially if there are several other Wi-Fi networks within range.
    Install a Wi-Fi app to see what channel you and your neighbors are using.
11. 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 astatic IP address prevents it from changing and relieves the router from having to do it throughDHCP .
12. Check for Android OS updates . There could be an update you have yet to apply that fixes this authentication problem.
13. 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 recreate the Wi-Fi network 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 before the authentication issue shows up. Since a full reset forces you tocreate a new Wi-Fi password from the router , it’ll kick off every other device on the network and reduce the chance of anIP address conflict .
14. Update your router’s firmware . If you’re still seeing the authentication error after a router reset, the software that runs the device could have bugs that only a firmware update can fix.
15. Change the encryption option to AES . Some users have had luck fixing the Wi-Fi error with this simple edit.
16. Factory reset your phone . This is one of the last things you have control over on your phone that 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.
17. Upgrade to a newer router . If the authentication problem only happens on your home network and works fine everywhere else, a modern router could be the fix.
18. Contact your device manufacturer (e.g., Google if you’re on a Pixel, Linksys if that’s your router brand), your network administrator, and/or theISP that delivers your internet.
    When youtalk 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 .
