as Jeff said - it could be that the MAC of the computer
is being used as the ONLY address the ISP will accept.
The router MAC would either have to be registered (however that happens)
with the ISP,
or some routers can "clone" a MAC address for this specific purpose.

For instance, with the COMCAST modem/router, the "learned" MAC address
becomes the only one it will service. This can be changed if the new device
(router) is plugged into the modem, then the modem is RESET (li'l button in
the back), not power cycled (that doesn't change anything, just a reboot in
the old config). After that, the COMCAST modem/router services the new
device just fine.

Some other ISPs have purported to "burn in" that registered MAC... haven't
vcome across one, though.
