I've done plenty of searching and none of the suggestions I've found on the internet have worked. I have an original white 360, build date 2006, with a black 802.11n wi-fi adapter. I get the "there is a problem with your connection" message whenever I try to connect to my university's wireless network. The Xbox has worked fine here for the last 6 months, but I started having this problem 3 days ago. When I go home again, I will take my Xbox and try it there, but that won't be for another couple weeks.
I've tried resetting all my network settings, redoing initial setup, and clearing the system cache. I even tried connecting to an ad-hoc network with my laptop to share the laptop's wired connection, and the Xbox gave me the same error (My iPod connected to the ad-hoc network and got online no problem). Is there a fix for this problem?? All the other post's I've seen were from October or November, have those people found solutions? It's strange the problem got me late like this. Any input would be rgeatly appreciated. If you need any more info I'd be happy to provide it.
