How to Fix WiFi Authentication Error in Android Device


One day I tried to use my Android to connect to a Wi-Fi network I have connected to before, but could not. I had to introduce the password again since I did a factory reset on my device a while back. After typing in the password and seeing that my phone was trying to connect, the only thing I saw was an “Authentication error”. Well, In this article, we are going to talk about How to Fix WiFi Authentication Error in Android Device.

I checked that I was connecting to the right network and made sure I was typing in the correct password. Still, that dreadful message appeared. Has this happened to you too? Here are some of the tips you can try to get rid of the problem and reconnect.

What happens when you enable Airplane Mode is that all radio-frequency signal transmission on your phone is turned off. You can use Bluetooth, WiFi, or also even make a phone call. This is a very useful tip because sometimes your phone’s mobile network interferes with your phone trying to connect to a network.

To give the airplane mode a try, swipe down from the top of your display and then turn off the mobile network and WiFi. Now, enable airplane mode and without turning this last feature off, go ahead and then turn on the WiFi option. If your phone connects to the WiFi network without any issues, then you can turn airplane mode off. Turn on Wifi and mobile network, and everything should be OK now.

Reset The Wi-Fi Connection | Authentication Error

Sometimes the answer lies in starting over, and that’s why resetting the WiFi connection could be the answer to your problems. Eliminating the wireless connection and then try to find/ connect to it again. This is a solution that has worked for many, and hopefully, it will work for you.

Go to your device’s Settings and tap on WiFi. Find the network you’re having trouble connecting to under WiFi Networks. Long-press on the network, either the SSID or name and you should see a small window with the options to either forget the network or modify network config.

Tap on the Forget Network option and distance yourself from the router until you’re only getting one bar signal. Once you have that one bar, connect to the network once again.

Wireless Network | Authentication Error

Another reason why you are having this authentication problem is that of an IP conflict. If that is your case, then the best thing you can do is change the wireless network settings from DHCP (default) to Static IP.

You can also instantly do this by going to Settings and once again going into the WiFi option. Long-press on the network until you see the same window as before. But this time tap on modify network config.

Tap on the advanced options box and look for the option that says DHCP. When you click on it, there is only going to be one other option that should be the Static option. Select it, and then you should see an IP address field.

When it shows, save the information you see in the static IP address field and erase it. Then type in the same data again and click on save. Only add the information if you are sure that it is the correct one. If you have any doubts, it’s best that you call your ISP (Internet Service Provider).

Refresh All Your Network Settings | Authentication Error

If the previous options have failed, then it looks like you have no choice but to refresh everything. By everything, I mean Bluetooth, mobile network, and also wireless network simultaneously.

To do this go to Settings > Backup & reset > Network reset and then click on Reset Settings. The process shouldn’t take too long, but when it finishes, try to log onto the network that’s giving your problems, and hopefully, you can connect.

Don’t worry about losing any important data since you won’t. This will though, wipe the data from all the connections you have ever made.
