Some cable companies lock the MAC address, preventing a new PC/router
from getting an IP address via DHCP after another client has already
asked for one on that connection.

For Mediacom, which I have, all I have to do is remove power from the
cable modem for a couple of minutes to clear the ARP cache after which I
can power it on and connect a new machine.  Comcast may require the
additional step of having somebody reset things on their side.
