C6300 CM certificate installed but no CM MAC address
I have a couple of netgear modem/routers for xfinity service. I cannot find any information on what is the CM certificate and CM MAC. On my C6300 which is missing the identity card, as normal, ...
Although curious what CM Certificate is and CM MAC. I simply subtracted 2 from my MAC address, the address you get with "arp -a" and from the modem. The installation with xfinity went as smooth as could be. So the modem I was told does not work and the hours spent trying to get xfinity to install it were all wasted. CM MAC = MAC-2. You would think this would be well known. But could not find the answer anywhere, Netgear tech service, xfinity tech service, google, etc. Hope this documents it.
Netgear has set up a community forum specifically for the Cable Modem products. Most of the people who watch that forum are more likely to have experience with Cable modems and know how to work it better than those of us who follow this router forum. Might be more likely to find someone who has a solution if the question is posted there:
