Fast, Stable, and Truly Future-Proof
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.

Excellent speeds! Highly recommend
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.

Great machine
Easy to set up, basically turn it on,let your provider know model and away you go. Pair with mesh system and it's a perfect setup.

CM2500 review
This CM2500 modem replaced my CM1100 modem. Setting it up was easy. It has worked flawlessly so far.
