This error message pops up on your screen when your device isn’t able to connect to a particular Wi-Fi network.

In this article, we are going to discuss a number of solutions that will solve your problem easily and quickly but before that, let’s understand what causes this error.

What is the reason behind WiFi authentication error on Android?

Let us take a look at how a Wi-Fi connection is established between your mobile and the router. When you tap on a particular Wi-Fi network, your device sends a connection request to the router along with the password for that network. The router now checks whether or not this password matches that of the one stored in its memory. If the two passwords do not match, then you are denied permission to connect to the network and the WiFi authentication error occurs. The strange part is when this error occurs on a familiar or previously saved Wi-Fi network.

There are multiple reasons why this error occurs. It could be due to:

1. Wi-Fi signal strength – If the signal strength is low, authentication error occurs more often. In this case, the users are advised to ensure the signal connectivity and try again after rebooting the device.

2. Airplane mode – If the user accidentally turns ON the Airplane mode on their device, it can no longer connect to any network.

3. Updates – Some system and firmware updates may also cause such errors. In such a case, a prompt will pop up asking you to re-enter the username and password.

4. Router – When the router function fails, it also leads to connectivity issues with Wi-Fi.

5. User count limit – If the user count limit for a Wi-Fi connection is exceeded, it may cause an authentication error message.

6. IP configuration conflicts – Sometimes, Wi-Fi authentication error occurs due to IP configuration conflicts. In this case, altering the network settings will help.

Here are some simple methods to fix Wi-Fi authentication errors in Android devices. The solutions may vary a little depending on the cause & model of your smartphone.

Method 5: Restart your Router

As mentioned earlier, a WiFi authentication error can be caused by your WiFi router. Due to a technical glitch, it is possible that the router is not able to compare the passwords and hence, give the green light to establish a connection. However, a simple restart can often solve the problem. Now, there are three ways in which you can restart your router.

How to Fix Wi-Fi Authentication Error

Alter connection settings – As mentioned earlier, you might experience the WiFi authentication error if there are already too many devices connected to the network and the maximum limit has been reached. The simple solution to this problem is to adjust the router settings to increase the maximum number of devices that can connect to the network. This is, however, only valid if it is possible to further extend the limit from what it is at present. Once you have done that, simply restart your router by using any of the two methods described above.
