I'm having the same problem, i try to connect to a university WiFi network so i cant really rest the router and everything i've tried with my N800 does not help
Talk to the uni network guys. Usually they're techno-geeks like us and will think the nit is cool, and try to figure out why it won't talk. As far as I can remember, I've never had a problem with wireless network connections.
