WPA/WPA2 Alfa AWUS036NH

[TheEnigma]

Hey guys, I have been having a horrible problem others seamed to have had a lot.
I cannot connect to my WPA/WPA2 connection but I can connect to unsecured networks with ease and no problems at all.
Whenever I try and connect to my BtHomeHub WPA/WPA2 Secured password with the right key it just gives me Bad Password, whenever I used the default wireless utility at the top right of the bar it just fails to get an IP.
I'm very very new to Linux as you can probably see.
I downloaded Wicd network manager etc but only get bad password.
The wireless works fine on windows to if that helps.
Wireless card = Alfa AWUS036NH
Any questions just let me know, thankyou.
Ubuntu 11.04

I have managed to find out I needed to change from WPA/WPA2 to just WPA2 but it hasn't helped at all.
I don't get bad password anymore it just simply wont obtain an IP address any help please?

If you are certain that your Alfa AWUS036NH is 'seeing' the Wireless Router(s) properly, then there is likely a conflict between Wicd and the [Gnome] Network Manager. Give post #5 on the following thread a try:
