Completing the above steps should connect Wi-Fi to your device. See if this fixes WiFi authentication error on Android. If it doesn’t work, then the problem is not the password. Hence, you will need to move on to the next solution.

3. Change the wireless network configuration

You will never connect if your Android device does not support signal transmission. Router blocking is not the only cause of the error. An unstable connection may be due to the selection of the wrong bandwidth.

• This happens when you don’t have the correct configuration. For example, your phone may support 2.5 GHz bandwidth instead of 5 GHz. There are many other similar reasons.
• If this was on your PC, you can try updating your drivers. But there is no such function for Android device.
• So the best thing you can do is go to your router settings and change the bandwidth from 2.5GHz to 5GHz and vice versa.
• Try several of these configurations until you develop a stable connection.
• You configure these settings by visiting the router’s admin panel.
• First go to a web browser and enter the default IP address.
• After that, you may have to provide a username and password.
• Go ahead and go to Advanced Settings.
• There are many things you can do there. For example, changing the fields of a static IP address.
• But that’s not what you’re here for. You are here to change the bandwidth setting.
• You will see a few steps below if you want to change the IP address field, among other things.

4. Use Android System Recovery

Sometimes system files can get corrupted which causes such errors. You can use Android System Restore to fix this issue as it is the most efficient way to deal with such crashes.

But you might think that you need programming knowledge to repair the system. Well, that’s not entirely true. There are so many third party apps that you can install on your device. After you download the app, you can run the system restore process through it to resolve this issue.

You can always try a system reset if you don’t want to use a third party app. Factory reset is an option that every phone has. Before doing this, you will need to back up your files and user data. This is to avoid problems in the future.

5. Change the IP address from DHCP to static

Double step back, you’ve been told Wi-Fi router configuration. This is one of those options where you change the IP. When the server fails to authenticate with DHCP, it causes an authentication error. So to overcome this, you can switch DHCP with a static IP. To do this, follow these steps:

• Open your Android device and go to its settings.
• Select “Wireless & Networks”and click “WLAN/Wifi”.
• Click on the network where the authentication failed.
• Now go to IP settings and open it.
• Change DHCP to static.
• Write down the static IP address on paper. Clear or delete all fields, and then re-save the static IP address.

Be careful when entering the IP address from the paper you wrote.

6. Check for Duplicate Wi-Fi Names

Sometimes people mistakenly connect to another Wi-Fi network with the same name. So make sure you don’t connect your device to the wrong Wi-Fi network due to duplicate names.

This happens more often when neighbors also have the same service. You and your neighbor may have the same Wi-Fi names. Thus, checking the network can solve this problem.

You can also use the “forget network”option to have the device find your home network again and reconnect to it. If your device already has the maximum number of networks it can store, forget about the network.

7. Try resetting your Wi-Fi network settings

The easiest way to overcome the authentication error is to restart the network. You need to delete the existing one and then try to connect again in order to complete this method. You can follow these instructions to reset your Wi-Fi network settings:

• The first thing you need to do is delete the Wi-Fi network. Go to your phone’s settings.
• Go to Wi-Fi and Network. Here you will find a list of networks that your phone is connected to or has been connected to. Select the Wi-Fi network you want to delete.
• Click on the “Forget”option to confirm your actions.
• A pop-up message will appear on the screen. Click Agree. This will delete all data and information about the selected network that you want to forget.
• Once the network is reset, turn Wi-Fi back on.
• Select the network you want to connect to and provide the required credentials.
• After entering the password, select Connect.

Following these steps will reconnect your device to Wi-Fi.

8. Change your IP settings

If the problem is deeply rooted, a network reset might not work. As a result, you will have to do extra work by resetting or changing the IP settings on your device. You can follow these steps to change the network connection on your phone:

• Go to “Settings”of your mobile phone and select “Wi-Fi settings”.
• In the Wi-Fi settings, you will have access to all the networks that you have saved on your device.
• To change the IP address, press and hold the network where you want to change it.
• Select “Manage network settings”/”Change network settings”in the new pop-up window.
• Now select “Show advanced options”.
• You will get access to the network settings. From there, go to the IP settings menu.
• Switch DHCP to static.
• Selecting static will provide you with additional options.
• Complete all options and select Save to save the changed settings.

Now go back and try connecting Wi-Fi to your device again. This time the error should be gone.

9. Change Network Security Type

Since the previous solutions didn’t work, it’s time to move on to comprehensive solutions. Sometimes your device selects the wrong type of security when connecting to Wi-Fi. As a result, there may be a collision with the security of your router by default.

This in turn causes a Wi-Fi authentication error. So, if this is the case, you can fix this problem by changing the security type. To do this, you will need to follow the following steps:

• Forget the Wi-Fi network that is causing problems.
• Now turn on Wi-Fi and select Add network.
• Specify a network name and select a security type.
• Click on the “Security”option to select your preferred security type.
• You will get many options to choose from. Select WPA/WPA2-PWe and click Save to save your changes.

Connect your device to Wi-Fi again to see if the error persists.

10. Use the latest Android firmware

An outdated version of the system software can cause several malfunctions in your device. As a result, it can also cause network-related errors. Therefore, to overcome this, you should check if your firmware is up to date. If it doesn’t, follow these steps to update it:

• Open “Settings”on your Android and navigate to “About phone”settings.
• Select System Update.

You will get the latest version if your device is out of date. Click “Update”to update the firmware.
