NETGEAR - Nighthawk 32 x 8 DOCSIS 3.1 Voice 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.

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.

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.

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.

This cable modem works well with xFinity/Comcast, able to get 2GB for streaming and 1GB on laptop based on NIC. I need to reboot about every two months to just clear up traffic. Easy to install and lights show connectivity. I used the phone lines for fax and landline.

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

This modem completes the replacement of a modem/router combo that I placed in passthrough mode, as its embedded router had failed to connect to a couple devices in my home. After having success with a new Netgear router, I got the modem to complete the upgrade. Except for the phone line, I was able get the modem installed and provisioned by Comcast without assistance. The phone line was another matter. Once I had an online chat established with a Comcast tech, we were able to get the phone line operational after several reboots. Since then, there have been no problems, and the internet is as fast as expected.

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.
