How To Fix Android Wi-Fi Authentication Error

Connecting to Wi-Fi is a necessary feature on a smartphone, and being unable to do so may be extremely annoying. There are a variety of reasons why a Wi-Fi authentication problem can occur. If you’re experiencing difficulties connecting your device to a wireless network, there are several things you can try to get it to work.

When the “handshake” between a router and a device fails, the authentication fault occurs.

Some of the techniques for resolving the Wi-Fi authentication error on Android are listed below:

1. Restart your computer.

If you get an authentication error, the first thing you should do is restart your device. This will usually solve most of your phone’s problems.

2. Turn on and off the airplane mode.

Turning your phone’s airplane mode on and off is another reliable technique to eliminate the source of authentication failures. In the connection settings, look for airplane mode. Turn it on with a tap, then turn it off with another tap.

3. Restart your network

1. Go to the device’s settings and select Wi-Fi.

2. Select the network to which you want to join.

Look for the option to “Forget Network.” Your phone’s network data will be erased as a result of this action.

3. Return to your Wi-Fi settings and choose the same network once more.

Allow it to connect to the network after entering the password.

4. Restart your network.

Almost all network problems can be fixed by resetting the network settings on your phone.

1. Go to the settings menu and select “Reset network settings.”

2. Select “Reset settings” and approve the reset when requested.

The settings for Wi-Fi, mobile data, and Bluetooth will all be reset to factory defaults.

You should now be able to connect to the network when all issues have been resolved.

5. Verify the maximum number of devices that can be supported.

It’s possible that there are already too many devices connected to the network, which prevents you from connecting. If you have access to the router, you may look at the settings and see what devices are connected. Reconnect after turning off a few devices.

6. Turn on the router.

It’s possible that the router is malfunctioning. Turn the router off for 30 seconds before turning it back on to restart it. After the router has been activated, try reconnecting your phone to the network.

7. Change from DHCP to a static IP address.

Your device’s default IP address assignment can be changed to DHCP. If this is the case, the authentication error could be the result of this.

Changing it to static could be a viable option.

1. Open the Start menu on any Windows PC.

2. Open the command prompt by typing cmd.

3. Type ipconfig/all into the command prompt and hit Enter. There will be a lot of information displayed, but you should just pay attention to the default gateway, IPv4 address, and DNS servers.

4. Make a note of the Gateway and DNS Server values you observe.

To identify an available IP address on your network, you’ll need to ping it.

5. To ping an IP address, launch PowerShell and type followed by the address you want to test, working your way up from the router’s IP address.

It will seem as follows:

10.0.0.1 ping

6. If the system displays a ping time, this IP address is already in use on the network.

If, on the other hand, the response reads “Destination host inaccessible,” it means the IP address is available and you can use it to connect your device to Wi-Fi. Make a list of the value you discover.

Open your Android device’s settings and locate your Wi-Fi settings to enter these numbers.

1. Press and hold the network you want to connect to for a long time.

2. Go to the Advanced tab.

3. Set the DHCP server to be static.

4. Fill in the blanks with the information you’ve gathered:

Using the Ping command, you discovered an open IP address.
gateway: the default gateway’s IP address.
DNS 1 and DNS 2: type in the DNS servers’ IP addresses.

All other fields on this form should be left blank, then tap Save.

8. Reset the device to factory settings

If none of these suggestions work, your phone can be reset to factory settings as a last resort.

On your phone, go to settings > factory data reset and scroll down to see the button.

All data, apps, and settings will be wiped when you push the button, erasing everything that is stopping the phone from connecting. Because this is such a harsh last step, you should back up your device first. Which of the aforementioned ways did you find to be effective in resolving Wi-Fi authentication issues? If you want to share your Wi-Fi network with your pals, you can use a QR code instead of revealing your password. To save battery power, you can also block Wi-Fi from going on automatically. That is the simplest and safest method for resolving the Android Wi-Fi Authentication Error.
