Did you find a solution? If so, what was it? I am encountering the same problem and trying to troubleshoot it but racking my brain to no end.
I have an HP Pavilion zv5330us notebook with a wireless card already built in w/ winXP & service pack 2. I am in a dorm room and I can pick up several signals and connect to them. The only thing is it says it is connected with a strong signal and when I go to click on internet explorer it says working offline and unavailable. What is wrong? What should I do?
