9.04 has known issues where the networking system can get its knickers 
in a twist with respect to the keyring, where it keeps the WPA/WEP key. 
So if the problem is that it can see the network connection but fails to 
connect to it and keeps prompting you for the pass phrase, it's likely 
to be this.

The good news is that it's easily worked around --- the simplest 
solution is to use wicd rather than NetworkManager. (The actual wireless 
*driver* is fine, it's just an issue with the front end, so using 
another front end solves it.) If you want to stick with NetworkManager 
then there's an easy fix... which, er, I can't find just right now. Sorry!

That's assuming that is what the problem is, of course...
