Android phones are capable of doing a lot of things. With time, it has developed leaps and bounds, and now it is possible to do almost everything on your phone. However, for utilizing your phone to the full extent, you need a stable internet connection. This is where your Wi-Fi comes in. Wi-Fi has become an absolute necessity in the urban world. Therefore, it is extremely inconvenient when we are not able 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.

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 1: Forget Network and then Reconnect

The easiest way to resolve this problem is to simply click on Forget Wi-Fi and reconnect. This step would require you to re-enter the password for the Wi-Fi. Thus, make sure that you have the correct password before clicking on the Forget Wi-Fi option. This is an effective solution and often solves the problem. Forgetting and reconnecting to the network gives you a new IP route and this could actually fix the issue of no internet connectivity. To do this:

1. Drag down the drop-down menu from the notification panel on the top.

2. Now, long-press the Wi-Fi symbol to open to the list of Wi-Fi networks.

3. Now, simply tap on the name of the Wi-Fi that you are connected to and click on the ‘Forget’ option.


4. After that, simply tap on the same Wi-Fi again and enter the password and click on connect.

Method 2: Switch from DHCP Network to Static Network

WiFi Authentication error can be caused by an IP conflict . If other devices can be affected by it, then so can Android smartphones. There is, however, a simple solution to this problem. All that you need to do is change the network configuration from DHCP to Static.

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.

1. Remove the power cord – The simplest and the easiest way to switch off a router is by disconnecting it from the power supply. For some basic routers, this is the only way to turn it off as they do not even have a power switch. Wait for a couple of minutes and then plug it back in.

2. Switch off using the Power button – If it is not possible to get to the router’s power cable, then you can also switch it off using the power button. Simply turn off your router for a few minutes and then turn it back on again.

3. 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.
