It may not be the cable.  Try another port on the router, as it could be the router.  It could even be the modem itself.  I have actually had a switch flake out on me (a 10 year old Cisco) that made three of the eight ports have this issue.  Replacing the switch on the fact that that's the only thing all three computers had in common worked.

So, just because you have low bandwidth on it doesn't mean it's the cable, especially since you've checked it out so thoroughly.  Time to start investigating the devices themselves.

HTH,
