WiFi authentication error on Android
Your phone can't confirm the WiFi password with the router. This is a password mismatch, the router having problems, or your phone's WiFi settings being corrupted. Forget the network and reconnect with the correct password.
An authentication error means your phone and the router can't agree on the password. Either you entered it wrong, the password changed, or your phone's saved credentials got corrupted. The frustrating part is the network is right there, but you can't join. Forgetting the network and reconnecting with the correct password solves most cases.
Fix-IT-Bot will walk you through each step — just tap, no typing needed.
