I upgraded from the Netgear C3000 to the CM1200. As a result, my wifi speed jumped from 18.0mbps to 118.0mbps, and I no longer need my wifi extender for far away devices. I love that I am getting top and reliable speed in my home.
Works very well, however the “easy to set up” instructions for Xfinity weren’t accurate, it required a love Comcast agent to capture the MAC address, etc. Connecting to Google Nest router was easy from that point on.
This device kicked butt right out of the box! I have WiFi camera security system that had been lagging with the cable company provided modem. As soon as I plugged in the Netgear Nighthawk modem, my router immediately pushed to its peek performance. My cameras are now crystal clear and no lag.
