Therefore, it is extremely inconvenient when we are not аble to connect to it.
There are several errors that might hinder a wireless connection and prevent you from accessing the internet. One such error is the WiFi authentication error. This error message pops up on your screen when your device isn’t able to connect to a particular Wi-Fi network. Even though you have made no mistake in typing the password or trying to connect to a previously used Wi-Fi network, you might still encounter this error once in a while. However, the good news is that this error can be easily fixed.
How to Fix WiFi Authentication Error on Android
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.
