I recently moved into an apartment where my new roommate has a wireless network set up.  When I try to connect it gives me the error message that the association request has been denied.  I have never had a problem connecting to any secured or unsecured network before. I have an Inspiron E1505 running windows vista home premium.  My roommate has XP. Is there a compatibility issue? Neither of us can figure out what is wrong, and tech support wasn't very helpful.  Any suggestions would be greatly appreciated. Feel free to contact me if you need more info. Thanks!
