- After getting the authentication error in your Galaxy S3, try to connect other devices to your network. If you have a laptop or other mobile phones, try connecting them to see if they, too, would get the same error. If they can connect just fine, then you already know the problem is not with your router/network.
- Try rebooting your phone first. Reboot often fixes simple problems so you should try that before you go any further. Once the phone is up, try reconnecting to see if you can.
- Go to Settings => Wi-Fi and make sure the toggle switch is on. Tap and hold on the name of your network to open its settings page. Once it pops up, tap on “Forget this Network” button.
- Let the phone detect networks in range and select the one you usually connect to. Enter credentials and try to browse the web to see if you can.
- If you can’t connect to your network still, try to find networks you can temporarily connect to and see your phone works just fine. If it does, then try using a different encryption type in your network. There were reports that S3 not connecting to a network that uses WPA2.
