Many of these systems assign access based on the hardware number, or MAC, of
the device that's connected and they only have one MAC on the system for you
at one time. The MAC of the PC is probably registered with the ISP and not
the MAC of the router. He can fix this a couple of different ways:

(1) Get the MAC of the router and have it registered as the device with the
ISP's server. The MAC is usually written somewhere on the outside of the
router. It will look something like 00:23:10:34:d6:78. Or, he can log into
the router and look on its info page.

(2) Most routers have the ability to impersonate another device. This is
often called "spoofing" in the router setup. He can get the MAC number of
his PC and tell the router to spoof the PC. This will fool the ISP's server
that it's talking to the PC and it will give the correct credentials to the
router. That's what I do with my Charter cable connection.
