Re: Modem

A modem with 8x4 channels should suffice for awhile. If you login or go to and select your speed level it will tell you what's an option.  If you don't want to buy another modem for several years then you want to consider going D3.1 which includes SB8200 / CM1000 / MB8600 devices.  


There are a couple of promotions posted by Comcast @  These are goign to be D3.0 devices which should be supported for a few years as well.
