There can be an issue with the wireless network or with your Android phone or both.

We have given the top 13 solutions in this guide to solve the authentication error Wi-Fi problem. You just need to follow these steps carefully.

Part 1. What Does It Mean When Wi-Fi Says Authentication Problem?

wifi-authentication-problem

The Wi-Fi authentication error occurs when you are unsuccessfully trying to connect to any Wi-Fi network with the correct password.

Normally, when you try to connect to a Wi-Fi network, the device will connect to that network and save the password. But with this problem, you will get a notification telling that it is authenticating and after a few minutes, you will see "authentication problem" under the network name you are trying to connect to.

When you are trying to connect to a Wi-Fi network, the device will first send a connection request, in an encrypted form, along with the password to the router. Then, the router will compare the password stored on it with the received data.

If the data matches, it will send a signal and the device will get connected. If it doesn't, you will get an authentication error. So, the Android Wi-Fi authentication problem will not let your device connect to the Wi-Fi network.

Part 2. Why Does Authentication Error Occur with Wi-Fi on Android?

The Wi-Fi authentication problem can occur due to multiple reasons. Let's see the possible reasons for this error.

  • Whenever the router malfunctions, your device will not connect to Wi-Fi and will deliver a notification saying an authentication error.

  • Have you recently updated your device? If yes, the issue might be with its drivers.

  • The connection between the device and router must be stable otherwise the authentication error can occur.

  • Are you sure you are connecting to the correct Wi-Fi network? You may try to connect to a network with the duplicate name for many times. In such a case, you will get the authentication error.

  • Sometimes, based on user's settings, the number of devices that can use the Wi-Fi network is limited. Your device won't connect to the network if that number exceeds.

4. Turn Airplane Mode on/off

Many of us use the Airplane mode either when we want to play a game without any disturbance or when we board a plane. Turning on Airplane mode can be useful because often the mobile network signal may interfere with the wireless network. When you enable the Airplane mode, the RF signal transmission on your phone is turned off.

Step 1: Open Settings on your device and turn off the mobile and Wi-Fi network. You can also do this by pulling down the quick settings menu.

Step 2: Now, turn on the Airplane mode.

Step 3: With the Airplane mode on, turn on Wi-Fi on your device and connect to the wireless network. If your device gets connected to the Wi-Fi network successfully, you can open settings and turn off the Airplane mode.

5. Check the Number of Supported Devices

Few modems can support only a certain number of devices. You need to check through the manufacturer or the service provider. Now, go to the Wi-Fi router settings and check the maximum number of devices that can connect to the wireless network. Increase the number of devices and save the settings.

6. Check Network Security Type

Sometimes the network security type can be a reason for this error. If you know the username and password of the wireless router, you can easily change the network security type.

If WPA is the security protocol, change it to WPA2 and vice versa. Now, in your Android smartphone, follow the steps given above and tap on Forget Network. After a few minutes, reconnect to the wireless network.

7. Check the Network Name for Duplicates

Often the authentication problem occurs when the username and password of the wireless network do not match. You might be confident of entering the right password, but the chances are that you are connecting to the wrong network with a similar name.

If you are connecting to some other wireless network by mistake, you will definitely experience this error. The only solution for this is to change the network name (if you are on the home wireless network) to avoid any confusion. Now check if your device is able to connect to the wireless network.

Conclusion

These are the top solutions for solving the authentication problem. After trying the above methods, we hope your device successfully got connected to the desired wireless network. You need to follow the steps carefully in order to solve this problem or you can give a try on Fixppo for Android. The authentication error can occur at any time, but now you know what to do when it occurs in the future.
