[quote name='fart_bubble']it keeps failing at the DNS part of the test and I've tried everything I can think of[/quote]What's the DNS server that's coming up on the 360? Is it 192.168.1.1 or something else?
192.168.1.1 would be the router, and if it's not set right, you'll get DNS issues from the 360. If it's something else, then it's coming from your ISP. As you said your computer's working OK, then I'd check the IP settings the computer has and compare them to the 360.
