[ubuntu] Home wireless network, bad password?!!!

view full story

http://ubuntuforums.org – I am trying to connect to my network, it is WPA PSK , I know the password is correct yet ubuntu keeps asking for the password over and over again. I tried to download WICD manager, Wicd returns the password as bad password. I switched over to BackTrack5R3, it's wicd accepts the password but can't get an IP. In my Win7 it works fine. How is this possible? What should I do? Thanks (Hardware)
