I just got a wireless adapter for my 360. When I ran the connection test the first time, everything was fine until it tested the xbox live connection. It said I needed to update, I said ok. Then some error ocurred and I don't think the update went though. Now when I run the connection test, it has an MTU error. My wireless router is a belkin 54g. Any thoughts? Thanks.
EDIT: I tried switching on Access Point Mode.. Now everything works great.. Except that I'm in access point mode... Anyways now I can't even change my router settings. When I enter the IP for my router, it just times out.
