Everything works great, but to be honest I can't tell if it's any faster. I got this cable modem because the coverage ran out on my router, so I figured I may as well upgrade both. The connection was fairly easy, but I had to contact Xfinity. The instructions said I could do it online, but that turned out to not be the case. I was pleasantly surprised that the first person I talked at Xfinity knew what to do. The whole process took about an hour but would have been less had I just called Xfinity right away. I did have an issue with the TV picture after everything was up and running. I had the previous cable modem behind the TV, and it didn't affect the picture, however, I had to move this modem a few feet away. It sits on the floor about three feet below the TV and there's no interference.
NETGEAR Nighthawk cable modem with voice was easy to set up (minutes) and has been stable since turned on a month ago. The default password is on the bottom, be sure to change it when you do setup.

Verified Purchase:Yes
I replaced my Netgear CM 500 with the Netgear CM 1000 as the 500 was very updated and could no longer get further updates. without changing my Wi-Fi at all, I went from 50 megs to 200! Everything runs smoothly… I’m thrilled (I was not thrilled with how difficult Xfinity made this to activate!)
