Brother's Samsung Galaxy 5 won't connect to Wi-Fi

My brother has a Samsung Galaxy 5 phone and whenever he tries to connect to my apartment's Wi-Fi, he gets an "authentication error" whenever we enter the password. There's no problem with my router and I rarely have problems using the Internet. I can connect to my phone's Wi-Fi just fine. How can we fix his problem? Thanks in advance!

Can this phone connect to other wifi networks?

Can you confirm that this problem isn't a capitalization issue?

If yes and yes, try changing the password on your router and see if that works.

I'll try that later when he's around, but I disconnected and reconnected to my Wi-Fi using my phone and I had no problem.

Re: Brother's Samsung Galaxy 5 won't connect to Wi-Fi

Already did both. Also, he's having a problem with his laptop as well. The laptop says it's connected to the Internet, but it says there seems to be a problem with the Wi-Fi.

Edit: So the solution for the laptop was restarting it and adding updates? It's now working. As for the phone, no idea. I added the network again and double checked the password, I still get an "authentication error" and "incorrect password."

Maybe try rebooting into safe mode?

A long shot, but go to Settings -> Language and Input and see what keyboard is selected. Maybe when he types in the correct password, the phone reads it as something else.

If there is an option to see the password when typing it then he could try that too

See if there is a software update available. I've had Android updates screw up things like WiFi and GPS. Had to wait for the carrier to push out fixes or even manually download and install them.
