Other causes include old router software, wrong network settings like conflicting IP addresses, or changing network security types like WPA and WEP. In this article, we will discuss several ways to fix this error.
1. Recheck Your Password for the Network
A small mistake in the WiFi password can block connection. Ensure it matches the network exactly, considering letters, numbers, and symbols.
2. Turn On Airplane Mode
Turning on Airplane Mode stops all network connections, including WiFi, to help fix network problems. Switching it on and off makes your phone try to reconnect to WiFi, clearing any temporary issues.
3. Reset Network Settings
If your Android device has ongoing connection problems, resetting network settings can help. This clears all saved WiFi networks, Bluetooth connections, and mobile data settings.
4. Configure IP Address
Sometimes, configuring a static IP address can fix WiFi authentication errors by preventing conflicts with the router’s DHCP server. This occurs when your device gets an IP address that overlaps with another or if automatic assignment fails. Manually setting the IP helps your device connect properly to the router. If none of the methods shown above helped you at all, you will need to contact your ISP for further assistance regarding this issue.
