Why Am I Getting an Authentication Failed Error?
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. 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. After doing that, reconnect your Android device to Wi-Fi by entering the password again manually. 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. 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. After completing this, you’ll need to create the Wi-Fi network again, and then reconnect your phone to it (see Step 3). 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. Choosing a different Wi-Fi channel number can help avoid interference, especially if there are several other Wi-Fi networks within range. 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.
