I had a similar problem a few years ago, only I was a residential
customer. When I first got their service, I plugged the cable modem
directly into the computer. I had to call them and give them the mac
address of that nic. Only after that nic was registered with them would
the service work. Later when I added a router and a second computer, I
had to call again and register the router's ip address.
I also knew the cable modem itself has to be authorized before it can be
used. Now here's the part I don't understand. Since they already know
what cable modem you're using, why do they also require a nic to be
registered before it can be used?
