NETGEAR - Nighthawk Mid/High-Split 32 x 8 DOCSIS 3.1 Cable Modem - Black

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.

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.

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.

just had it for 2 weeks and so far it is excellent but only time will tell...

The Nighthawk works just fine; however, you have to contact the phone manufacturer to ensure all the options for your phone are activated.

Replaced old modem, went from 700Mbps to 1.4 Gbps, easy setup, couldn't be happier with purchase

I still have not managed to get connected and working. And calling the whole number is worthless.
