I'm in a college campus, and when i hooked my computer up to the internet, it was just plug and play, plug it in and bam.. thats it, but my roommate's computer wont do that. When i hook it up, it says its connected but when i open internet explorer it says its offline, i've tried everything i think even setting up new connections and all, but to no avail. its on windows xp, any advice is appreciated.
