Authentication Error Wifi Issues – Here Is How To Fix It

Turn On Airplane Mode

Sometimes, your data connection or Bluetooth, if turned on, might be the reason why your WiFi refuses to connect to a WiFi network and pops in the authentication error as it might be interfering with the radio signal being passed across to your device.

These radio signals include your single or dual SIM cards (depending on the phone you’re using), Bluetooth and WiFi.

However, you can still go back and turn your WiFi on while the airplane mode is still turned on. Now, when you turn on your WiFi, search for available WiFi networks, provide the correct password to the WiFi network and connect.

You should also note that this will wipe all your Bluetooth, WiFi and mobile data settings but won’t affect your files or apps on your phone. To do this, navigate to your Settings Menu, Click on Backup & Reset and Select Reset Network Settings. Doing this will hopefully fix the issue and allow you to connect to the WiFi network.
