Thanx for the suggestion.

Jetskier,
You probably got a new ethernet cable with your new router. I would replace the cable anyway. A bad cable can always cause tons of chatter, duplex mismatches, and/or TCP resend requests which could saturate the upstream side of the modem. This could also cause drops to occur to the modem from Metrocast's head end (due to the saturation of the link).
This may not be the fix, but it is an easy thing to test and I can not tell you how many times a bad cable has halted traffic on gig links. Always start with the physical layer and move up the stack..
