Netgear Nighthawk DOCSIS 3.1 High Speed Internet Cable Modem

Decided to upgrade my old CM1100 used with Xfinity (300 gbps download / 30 gbps upload) with CM3000 to get the 1 gbps download and 100 gbps upload speed on my revised Xfinity Internet service. Installation of CM3000 was very easy. And activation of new modem with Xfinity was done quickly and was running with upgraded services with CM3000 in less than 30 min. I highly recommend CM3000 if you plan to have more than 1 gbps download/upload speed for your home/office. And you can save on montly renting fee by owning your own modem.

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.

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.

Great modem and easy to set up with the provided instructions.

Awesome modem!! So fast and easy setup in seconds!!!! Highly recommended!!

This is my third Nighthawk product from Netgear. The reason for multiple products is to keep pace with upgraded service from my ISP, I've never had an issue with any of my Nighthawk products. They work as advertised. I have Xfinity home internet, and pair this top-tier cable modem with an Orbi mesh wifi system, which is also a Netgear product..

Excellent modem and perfect paired with Nighthawk RS600 WiFi7 Router. It's nice to be up to speed in the 21st century. Now if can just get my local ISP to install fiber it would be the full package, coming soon… Thank you Netgear :).

The setup was easy and straightforward. I experienced less lagging and buffering since I upgraded my modem. My devices are experiencing better performance.

Unfortunately I was made to upgrade by Xfinity to a new modem even though I had a perfectly fine docsis 3.1 modem not even 3 years old, to access the newly available "next gen" upload speeds. I began searching for a unit that was not some sort of atrocious combination modem/router/ap and came across this. Set up through Xfinity was painless and this modem is running like a champ for a few weeks now. I now have 6x the upload speed as I had before, which is quite nice. Would recommend to anyone in need of a modem certified for mid/high split, "next gen" speed, or whatever terminology your ISP chooses
