Go to your device’s Settings and tap on WiFi. Find the WiFi network you are having trouble with connecting. Long-press on the WiFi network, You should get a small window with two options “Forget Network” and “Modify Network Config”. Tap on the Forget Network option then type your password and connect to the network once again.

Change Wireless Network

Another reason for “authentication error” is that of an IP conflict. If that’s your case, then the best thing you can do is change the wireless network setting from DHCP (default) to Static IP.

You can change this by going to your device’s Settings and going to the WiFi option. Long-press on the WiFi network until you see the same window as before, but this time tap on modify network config.


Tap on Advanced options and find an option that says DHCP. When you tap on it, there is only going to be one other option that should be the Static option. Then select it, you should see an IP address field there.

Just save the information that you see in the static IP address and remove it. Type in the same data again then save it. Only add the information if you’re sure it’s the correct one. If you have any doubts, it’s best that you call your ISP (Internet Service Provider).
