Go back to cox. Qwest Telechoice sucks. Has horrible ping and download spikes. And like you said it worked with cox. The only good thing about telechoice is the upload speeds for the money but even the uploads arent that consistant. How is telechoice in terms of speed/latency for you? Anyways try connecting directly to the cable modem to se if it works. Make sure all the DHCP settings are on auto. You might need to have the same mac address as your computer on yout xbox or change the same mac address as the computer on the router. Make sure you unplug then plug everything back up again after you try each different method.
