Android shows WiFi authentication error
Authentication error means your phone and router disagree on the password. This is a password mismatch, the router having problems, or your phone's saved credentials being corrupted. Check the correct password, then forget and reconnect.
An authentication error means your phone tried the password but the router said no thanks. Either you typed it wrong, the password changed, your phone's saved credentials got corrupted, or the router is having a problem. Forgetting the network and reconnecting with the correct password fixes most cases.
- ✓Have the WiFi password written down or visible — check the router sticker
- ✓Keep mobile data enabled so you can still access the internet while troubleshooting
- ✓Stay near the router while testing the connection
