I'm planning to buy my own modem (MB7621) to use instead of the that I'm currently renting from Comcast. I just wanted to confirm that Comcast Business supports that modem, and to understand what the steps are to make it work with Comcast.
I checked the compatibility page below and it seems MB7621 is compatible with my current plan. I also don't use Static IP or any incompatible other features listed on the pages below.
Hi there! I'd be glad to ensure that this gets looked into further. Please click on my handle (Comcast_Robert) and send a private message with your name, the business name, the complete service address (including city, state, ZIP, suite number, etc), and the phone or account number, and any pertinent details-- like the ticket number(s)-- so we can help.
