It looks like a lot of people are having success getting a second IP Address via the forums. I have a Netgear Nighthawk CM1100 and would like to get a second IP Address to enable the second LAN port. I have tried the typical customer service route and they seem pretty confused as to what I am trying to acheive.
They are phasing it out but I'm going to escalate your issue to the Comcast corporate employees that are available to these boards. We've seen cases here where they have been able to get this accomplished for customers even when it is not listed in their rate cards, YMMV. You should get a reply here in your topic. Good luck !
Hi there, NVollmers. Thanks for posting here in the forums for support. I would be glad to see what we can do to help you out. Please send me a PM with your first and last name and I will see what I can do. If we do have the option to add this service, there is usually a charge of $4.95 per month for it.
