Also other machines on the LAN can not really get out at all. If you ping/traceroute, do you see losses (and where)?

(I'm guessing big time here - not an expert by any means) If your cable modem provides IP, it's probably not involved in the DHCP negotiations. Does your IP address change before you start to see this slowdown?
