If the Wi-Fi settings screen on your Android phone or tablet reports an authentication error, you won't be able to connect to the internet. Here are a few things you can try to resolve the problem and get back online. Learn how to resolve authentication issues on a mobile device here to spare yourself the stress and headache!

What Causes the Authentication Failed Error?

There isn't a single, obvious cause for this issue, but we'll look into  some of the following:

• The password you're using is incorrect.
• A hardware issue with your phone or network.
• A shoddy router connection.
• The network configuration is broken.
• The frequency band is proving to be difficult for your phone to handle.

Part 1. How to Fix Wi-Fi Authentication Problems on Android

The items you ought to try are listed below. From the wide range of users who have encountered this issue, we've compiled all the top solutions. Try the simpler solutions first by making sure to go through this list in the order in which we've arranged it.

Step 1. Switch off and off the aeroplane mode

 The wireless radios will essentially restart when this feature is turned on and off, forcing an attempt to connect to the Wi-Fi network.

If you are confident that you haven't recently changed the Wi-Fi password and that the network and your phone are both functioning properly, this is the most likely solution to the problem.

Step 2. Reboot your phone

Restarting your phone (also known as rebooting) is simple and frequently resolves issues like this one.

Step 3. Delete the Wi-FI network from your phone's list of saved networks to "forget" it

Access the Wi-Fi settings, then open the gear/settings icon next to the network displaying the error, and select Forget.

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

NOTE: Carry out this step even if you are certain that the password is correct. Before we move on to the more advanced concepts below, rebuilding your Wi-Fi network in this manner is helpful even if you have used it hundreds of times in the past.

Step 4. Reset the network configuration on the phone

Resetting network settings removes all network-related data, including all saved Wi-Fi networks and other related information, not just the data you "forgot" in the previous step.

The objective of this process is to reset as much as you can without erasing any of your private files (1the last step below). Reset Wi-Fi, mobile, and Bluetooth by going to Settings > System > Reset options. Following this, you must try to connect to the network once more.

Step 5. Router broadcast frequency

If your router broadcasts on both frequency bands with the same SSID and password, and your network hardware allows it, separate the 2.4 GHz and 5 GHz networks. Changing the network name and password for one of the bands has worked for some users in order to resolve this Wi-Fi authentication error.

If you see two networks with the same credentials, it's possible that the phone becomes confused or enters hyper-secure mode, which prevents you from accessing either one. Consider this a slow internet connection that needs to be fixed. The authentication problem could be brought on by factors like signal interference and bandwidth overload.

Step 6. Contact your network administrator

Your device's manufacturer (such as Google if you use a Pixel or Linksys if that is the brand of your router), and/or the ISP that provides your internet service.

When speaking with tech support, be sure to detail everything you've already tried (everything on the above list), as at this point you've done everything you can and all that's left is to alert those companies, as the problem seems to be with one of them.

If your phone is broken, depending on who you contact, they might be able to try a hardware repair; alternatively, your internet service provider or hardware manufacturer can look into your router/modem further for Wi-Fi-related issues. The network administrator may occasionally need to make security adjustments.

Step 7. Your phone should be factory reset

The last thing you can change on your phone to make this problem go away is this. All customizations on your device, including any locally saved media files, apps, etc., will be completely erased.

NOTE:  Do all of the aforementioned before moving on to this step. Before making this drastic "delete everything and start over" move, you need to make sure the network itself isn't experiencing a problem. Put this off until the worst case scenario, when you are certain that the phone, not the network, is at fault.

Step 8. Update the Andriod OS,if necessary

Although this requires more effort than the other steps, there may be an update you haven't yet applied that resolves this specific problem. Before proceeding to the final step below, it's at least worth a try.

Step 9. Reboot the network hardware

If you're using a public network, like at a coffee shop or library, you might not have the authority to do this, but try your best to finish the step.

There isn't much left to blame for the authentication issue other than the router once the password and phone have been addressed. This is especially true if there is only one network where you have trouble connecting to Wi-Fi, but you have no trouble at all on any other networks.There are big differences between restarting and resetting. The network is being restarted/rebooted in this specific step, which is essentially the same as restarting any tech device.
