They also appreciate its compatibility, DOCSIS 3.1 support, and affordable price, noting that it operates without lag and stays cool.

    This a great cable modem to use at home. I truly recommend it when you are trying to connect to your cable provider. We had to return it ours because our cable provider said we didn’t need one. The cable company use theirs and we were already being charged on our bill for the cable modem box.

    Bought this to replace an Arris modem Cox gave me that combined DOCSIS 3.1 and telephone because that thing was junk (internet dropping 5-8 times per day, every day. This thing is effectively invisible with no interventions required since installed it. Highly recommended.

    I always upgrade my internet hardware to ensure I’m getting the speeds I’m paying for as well as keeping my network updated and safe. The speed of your internet will depend on what plan you have and this router will keep up with the fastest residential speeds.

    Great Cable Modem.

    I bought this modem because I canceled some services with my local cable service and in doing so I had to return my phone/internet modem and I did not want to pay to rent a cable modem from my local cable co. I bought this modem because it is a Docsis 3.1 and it future proof as for internet speed tiers.

    we signed up for Mediacom internet and chose to purchase a modem outright rather than pay a monthly rental fee. This is one of the modems they recommended. I was familiar with the netgear brand so chose this one. works great!

    Reliable and solid gear. Although I initially had some difficulty accessing the configuration menu due to network settings, the modem has been consistent and maintains a solid connection to my ISP (once they replaced the water-filled, damaged cable to my home).

    Bought this on a recommendation from a friend that works for Spectrum. He said to buy this to save on the monthly rental charge that Spectrum charges its customers for their Cable Modem. This one is way better and saves you money in the long haul. What more can you ask for?!

    I always read the negative reviews for problems. That's why I'm rating this 3 stars. It really should be a 4 star. I connected a laptop directly to the modem to get it configured by Xfinity. After that, I connected my Netgear mesh router to the modem, but the router can't connect to the internet. I had to call Netgear support. They walked me through a long sequence of various on/off and connections of cable and ethernet. After that, everything works fine. I'm getting fantastic speed. It's possible that the problem is with Xfinity, but I doubt it. I just think that Netgear equipment should plug and play. It was a very frustrating few hours.

    Docsis 3.1 while a minute technical details enabled our new cable modem service to deliver 1 Gbps to the house over Gigabit Ethernet service. Of equal importance is using this you avoid paying Comcast $12 / month. Amazingly there are still people paying AT&T & Verizon / month for their home phone handsets!

    My cable company has the option to purchase your own modem as long as it was compatible. It was the best investment. I'm saving hundred of dollars each year not renting a modem. I have gigabit service and i still get the full range of my internet. It a great modem.

    This has been a solid modem. It was very easy to set up and I haven't run into a single issue with my ISP while using it. I have recommended this modem to all my friends who have been looking to upgrade to wifi 6 on their home network.

    I originally purchased an ARRIS SB8200 cable modem when I upgraded to 500 Mbps service with Mediacom. The connection was unstable and I experienced a lot of random disconnects. I returned it and purchased this modem which has proven to be very stable and provides speeds that are fast and consistent.

    This modem has been very reliable, with a rock-solid performance. The reporting/logging capability has helped diagnose issues with the internet provider's distribution system and quickly squelch their attempts to blame my internal network.

    Purchased to replace an older modem that was no longer compliant with current security standards. Easy plug and play setup with the Comcast app. The speed has been as expected and logging into it to check settings was easy as well.
