WiFi networks have become far more widespread and hence crucial than ever. Not only do they almost always give you better internet speed as compared to mobile data, but they’re also more stable and therefore better for doing things such as video calls and online gaming.

In this article, we’re going over the WiFi authentication error you might run into on your phone and giving you a few steps on how to fix the problem.

What does authentication error mean?

As you can probably guess by the error itself, it means that there is some authentication problem when trying to connect to a WiFi network. Now, this can happen because of something as simple as you’ve entered the wrong network password or something more technical like an error in the router’s IP assignment or just about anything else.

How to fix authentication error?

Here are seven ways to fix the authentication error on your device.


The first rule of troubleshooting anything tech is to restart the device or, in this case, reconnect. Sometimes that’s all it takes. Next, double-check the password you’re entering to ensure you’re doing it right. 

Toggle the Airplane mode

Toggling the Airplane mode on and back again has roughly the same effect on your device as restarting, except it affects the network more than the device. 

If you’re having trouble with WiFi, pull down the notification shade to access the Airplane mode setting. Toggle it on, wait for all the connectivity to drop dead, and then turn it back on again. 

Try forgetting the network

Sometimes, you may have to go the extra mile and altogether remove the network from your phone before joining again.

Make sure there are no access control settings enabled on your router

Ensure no traffic control settings are in place for your router. If that doesn’t resolve the issue, reset your router and try again.
