    Comcast now boasts that they have gigabit speeds, great right? Not when their own modem, THEIR OWN MODEM restarts eight times a day. Bought this guy and not only is it reliable, but it also is 10% faster than Comcast own modem as well! Props guys.

    JUST RECENTLY UPGRADED TO COMCAST GIGA BIT INTERNET SPEED AND BOUGHT THIS MODEM TO HANDLE THE SPEED. WORKING GREAT SO FAR. I AM TOTALLY SATISFIED. NEEDED A DOCSIS 3.1 MODEM FOR GIGA BIT SPEED AND THIS MODEM CAN HANDLE IT. SO FAR SO GOOD

    Does exactly what you’d expect for a modem. No more bottleneck on my network. Now I can download and stream quickly and with ease. Installation was easy. Just plug it in and it does it’s thing.

    Easy to install, much less visible than the Motorola Surfboards I have owned and easier to understand indicator lights. Outstanding performance getting gigabit speed even on wireless devices. Certified by Cox. Highly recommend.

    Netgear cable modem setup was easy with Mediacom. Just call Mediacom and give the the numbers on the modem. Plug it in and go. I need to pair it with an ax wifi 6 router to truley evaluate it's performance. Midem appears very fast with a gigabyte plan from medicom and my old n router.

    This is a great modem! I upgraded my service to do 400mbps and this is just what I needed. My last modem could only go up to 250, so that wasnt going to cut it. Installation was easy and it looks pretty slick next to my nighthawk router.

    Solid cable modem. Needed to upgrade to DOCSIS 3.1 and this one has been solid for 9+ months of ownership. Don't know if I've ever had to reboot it or spent time doing any type of troubleshooting on it.

    I waited too long to upgrade my modem to this model and missed out on faster speeds available through my carrier, Comcast Xfinity. Since upgrading, I've noticed not also faster downloads but fewer needs to restart. Very good product.

    I purchased this modem to get ready for Docsis 3.1 on Comcast. Even though it is operating as a Docsis3.0 modem right now, it has been rock solid. No noticeable dropouts or need to reboot.

    Smooth, crisp and fast. Easy to use and stable once connected. A bit more powerful than I initially need but bought with the idea of future proofing and wouldn’t look back. Would definitely recommend.

    A bit overkill for my needs but no lag when streaming pairs nice with the Netgear nighthawk. No lag when playing video games. Fastest internet I’ve had.
