“Authentication Error” is one of the common errors that we have encountered at least once while trying to connect to a Wi-Fi network. The device refuses to connect with the Wireless Network no matter how much you try. The authentication problem occurs both in Android phones and computer. The problem even occurs on iPhone, iPad and Macbook as well. There can be multiple reasons as why your phone or laptop can’t connect to wifi network.
The authentication problem occurs when you try to connect a Wi-Fi network with the right password and the device refused to connect. Normally the device saves the password entered and gets connected to the network. However in this case a message is delivered at the bottom saying “Authentication Error” or “Authentication Problem”. The error can be removed by following some simple troubleshooting steps. You can follow our below guide to fix the Authentication problem in Android, iPhone and computers.
How to fix Wi-Fi Authentication Error Problem
The connection problem can be fixed in many ways. We are going to provide your multiple troubleshooting tips to fix Android WiFi authentication error.
The Password Problem
A wrong password is the major issue in getting the authentication error. Make sure that password entered is correct. You should also check for the Capslock ON/OFF key. Normally people don’t type in their password that has capital letters especially on home networks or their mobile hotspots. The Capslock key becomes ON by mistake and people keep tying in their password on the network and it keeps on giving Authentication error.
If you think that you are entering the right password and the problem still exists then you should take another device. Connect that device to the network that you are trying to connect and enter the same password. If the device gets connected then you have the right password. Most of the time the password check will solve the problem.
Forget the Network and Connect Again
The second method is one of the best methods to fix the problem. You can try to reset the connection between device and wireless router. It can be any device such as Android phone, iPhone or Computer. In computers you can directly delete the network. You can reset by forgetting the connection from the wireless settings. You can remove the Wi-Fi connection and add it back as new connection. It will fix the connection 90% of the time.
