There are various reasons causing this issue, leaving you confused. But not anymore. This guide will help you understand the possible causes and 12 ways to fix Wi-Fi authentication problems on Android. Let’s get into it.

Reasons for the Wi-Fi Authentication Error

There’s no clear path to the root cause, but there are multiple possible ways. Some common issues include:

How to Fix Wi-Fi Authentication Problems on Your Android Device

Now that you know the possible causes, let’s fix it with the following 12 ways.

One of the easiest and most efficient solutions is toggling on Airplane mode. This action shuts off the wireless components of your hardware, cutting off connections and rebooting them. This step involves two methods. Allow me to explain.

Step 1: Open your phone Settings and tap on Wi-Fi & Network.

4. Reboot the Router

Restarting the Wi-Fi router is another simple step that can help resolve any issues with the router’s settings. To do this, turn off the router and wait a few minutes before turning it back on. Give it some time to function properly, and then try connecting your phone to see if the network is working.

5. Check for Duplicate Wireless Network Names

One of the most common errors users make is forgetting or entering the wrong password, resulting in a Wi-Fi authentication error on the phone. So, ensure the correct password is entered.

If you have multiple access points/Wi-Fi routers with the same name, you will inevitably encounter this authentication error on your phone. To resolve this, avoid using the same SSID for all the routers. Differentiate them with a unique name, number, or frequency, such as drawing room, bedroom, or home 1, home 2. Alternatively, use one password for all the Wi-Fi routers.

6. Check the Maximum Supported Devices

Your router is unlikely to reach its maximum device limit, especially if it is a private network. However, when there are many guests, the internet may slow down. This is because the router’s limit will be exceeded, causing an authentication error on your phone. Here’s how to check the number of connected users on your router.

If you don’t know the credentials, check your router’s back. It is often in the admin/admin or admin/password format. However, if you have changed that previously, enter the new credentials.

7. Reset the Phone’s Network Settings

If none of the above steps fixed the issue, this one likely will. This step will reset the phone’s network settings and start from scratch. Let’s begin.

Almost all routers have a manual button at the back to reset. Just press the button until the lights go off and turn back on. The router will then reset, and you’ll need to set it up again to use.

11. Changing the IP Address From DHCP to Static

Most routers use DHCP to assign IP addresses and configuration information. However, this can lead to IP conflicts and network disruption. To fix this issue, assign a static IP address to your Android device. Follow these steps:

1. Go to Settings and select Wi-Fi & Network.
