MP 1,1-5,1 Can't connect to 5ghz, wrong password?

[macpro00]

Mac 5,1 won't connect to my 5ghz network - it says wrong password even though I am 100% sure the password is correct. My other devices connect to 5ghz. It only connects to 2.4ghz. Help!

Poor signal? That can cause this "password error".

2.4GHz signal is easier to penetrate the walls.

1. Country Code US, is your other network hardware US, too ?
2. Is that an Apple Airport Card or a aftermarket one ?

Yes, all are US and I am located in the US. It's an Apple Airport Card. My router is about 20ft away from my MP 5,1.

What channels and width are you attempting to use with the router?
