Hi Bigerrons,
Welcome to PCHF. We have some extremely talented networking guys here, and I am sure that we will be able to get you back up and running.
First of all can you please give us the information on both the old router and the new router?
Have you tried manually changing the IP on your PC to allow the XBox to have the automatically assigned one?
Looking forward to your reply,
TTFN
LGW
