NETGEAR - Nighthawk 32 x 8 DOCSIS 3.1 Voice Cable Modem - Black

Set up was straight forward and we noticed faster internet on Comcast right away. Had to get a separate router and that is probably part of the speed increase as well. Activatioin on Comcast account was smooth and phone worked right away. We hope the will give us a more stable phone line. The old modem dropped the phone weekly.

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.

Upgraded to the Nighthawk CM3000 with Xfinity and the difference was immediate. Setup was quick, activation was easy, and I'm consistently seeing near-gigabit download speeds with noticeably improved upload performance. The connection has been rock solid and pairs perfectly with my mesh Wi-Fi system. Great performance and worth the upgrade.

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!)

The Netgear CM3000 modem solved a problem I had streaming 24 bit / 96 kHz hi res audio files where music would stop after a track or two and not advance to the next track. This problem was with the Netgear CM1200 which I bought in 2024. Not a bad router, Internet speed was decent, ~950 mpbs on my Xfinity 1100 speed plan and I could stream video files fine. But high res audio is different b/c the files are not cached. I figured the CM1200 was contributing to a data latency issue and packets were getting jumbled. The CM3000 was Xfinity recommended (which means they'll push firmware updates to it) so I bought it. It has a little smaller form factor than the CM1200 which is nice. Setup using the Xfinity phone app was a breeze. Solved my high res audio file latency issue immediately. I'm a happy camper.

Extremely powerful. Easy to setup, except the additional task of calling Cox to allow it to be recognized, since their online verification of the modem didn't work. But that's not Netgear's fault. Overall I'm getting impressive speeds over 2Gbps to my wired desktop, & over 1Gbps to my phones & iPads.

connected seamlessly. Only challenge on the Comcast side for connecting. Took comcast about 45 minutes to complete things on their side.

The modem is fine but I did have to have an Xfinity tech out to set it up! My biggest complaint is that using a Netgear modem for 5 yrs. they sent me a routerless modem, SO I had to buy a separate router. Netgear's rcommendation should have been compatible w/ their previous product!

Well I never got a chance to use it. Xfinity bricked the modem on the activation process. So I just went with their modem because I could not wait for another modem to be delivered. So make sure you have a good connection and no outages are happening so the modem will not get bricked on the activation process.

I received an email from Netgear informing that I needed to replace my CM2050V with a new CM2050V. Before I replaced my 0ld 2050V with the new 2050V I had sporadic issues. My internet connection was not constant and I needed to unplug my modem and reboot weekly. When I installed the new modem my WiFi coverage would fluctuate within a few minutes and I would have to reboot in order for example to get clear voices on Zoom. My lengthy call to support resulted in a recommendation to contact Xfinity. The plug and play part of installation always worked. However, my internet was in fact steady and the problem was clearly the Netgear modem. There appears to be a need for Xfinity and Netgear to update firmaware etc. I am returning the modem because it clearly does not work and I have installed the Xfinity modem/router.
