There seem to be two different kinds of cable authentication in the US.
They both capture the MAC address of the device that is authorized to
connect. On the more popular type, there is no manual registration. If
you turn the cable modem and your router off for about 10 minutes, then
turn on the modem, let it sync, and then turn on the router and let it
sync, it may be authorized.
On the other type, manual authentication is required. Typically, this is
performed by opening a browser to a captive portal web page from the
primary PC, hooked directly to the cable modem. Any web page opened is
redirected to the registration page (just like at many WiFi hotspots).
Later, when you connect your router, the MAC isn't the same, and the router
has no way to present the redirected page to your PC on the other side of
the router. You could call the cable ISP and tell them you want to connect
a router. They will ask for the MAC of the WAN side of the router, and
register it.
Or you could access the registration page through the router, if you know
the address. Some cable techs know the address, so that they can do the
initial registration with a router in place. I made note of the IP address
the tech used, but I see that the name is available with a Google search of
mediacom registration url. Maybe you could find yours.
Or you could "clone" the MAC address of the PC that is already registered
with the cable company into the router. You didn't say what router you
have. Some have a place to manually enter the MAC address that you want to
present, some will read the MAC address of the PC you are using and offer
to use that.
