NETGEAR Cable Modem CM1000 / CM1000v2

However, this would be the last cable modem you’ll need for many years to come. It is compatible with most cable companies including Comcast XFINITY 1 Gig, Cox Gigablast, Grande 1 Gig, and more.

What is the difference between the NETGEAR CM1000 and CM1000v2?

The only difference between the two is a couple of minor hardware changes inside of the modems. They both operate the same and will be approved by your ISP as the same. Basically, when NETGEAR went to manufacture more of these, the original hardware was not available so it had to be substituted.
