The other possibility is that the modem is really dumb about negotiation
and the new router was different than the old in that respect.  Most
cable modems auto-negotiate not only between 10/100 and Half/Full duplex
but also Crossover/Straight cabling.  

I've pulled cat five out of the back of a computer (which expects straight
cabling) and plugged it into an uplink port of a router (which expects
crossover) and had it fail exactly as you saw.  A power reset on
the cable modem fixed this.
