5. Check The Number Of Supported Devices

As mentioned earlier, there’s a limit as to how many devices can connect to a WiFi network.

If your WiFi network has reached that limit then disconnecting the inactive devices from the WiFi network might resolve the WiFi authentication problem.

6. Check The WiFi Network Name For Duplicates

One of the primary reasons behind the occurrence of the WiFi authentication error is an incorrect username and password.

If you are confident that the password entered by you is correct then you might be connecting to a different network with a similar name.

In order to prevent this error assign a unique name to your WiFi network. Once fixed, your device will connect to the wireless network flawlessly.

7. Verify Network Security Type


Another simple problem that might cause WiFi connectivity issues is the type of network security that has been applied to your WiFi network.

If you have access to the username and password of your WiFi router, you can simply change the network security type.

If the security protocol is WPA simply change it to WPA2 and vice versa.

8. Modify Wireless Network Configuration


If any of the simple solutions didn’t work for you then you can resolve the WiFi authentication error by changing the wireless network configuration settings from DHCP to Static IP. Generally, DHCP is the default setting.

In order to make these changes follow these simple steps.

  • Open WiFi under Network Connections from the Settings of your smartphone.
  • Locate the WiFi network you are trying to connect to and then long-press on it.
  • Choose Modify Network and check the Show Advanced Settings box to change the network from DHCP to Static.
  • Next up, note down the information showed in the IP address field below.

If you think that the above-mentioned fix is a bit difficult for you to understand then you can simply contact your ISP and ask them to modify wireless network configuration for you.
