Customers are saying

Customers are positive about the product's impressive speed, strong performance, and overall ease of use, including its simple setup and seamless connection. They also appreciate its compatibility, DOCSIS 3.1 support, and affordable price, noting that it operates without lag and stays cool. However, customers are negative about the limited number of ethernet ports and, for some, the signal strength.

    Immediately my download speed goes up to 500+mb (was about 80mb). Xfinity asked me to upgrade my device and I got the speed as expected with this new Modem.

    Replaced a Motorola Modem. Best decision on that move. Easy to set up.. Take out of the box, call provider, give them info, and then plug-in power, coaxial, and ethernet. Give it a few minutes to register on the network and your ready to surf. I connected this device to a Mesh Network and the coverage is great!

    I finally got fed up with resetting my cable company provided modem 1-4 times per day. I bought this one to be prepared for when DOCSIS 3.1 becomes the norm. It has been really fast and I have yet to need to reset it in the month I've owned it. Very pleased.

    Recently upgraded our internet service to Cox Preferred 250 (250 MB/s), and this modem is definitely needed to enjoy the high speed. So far no issues.

    Replaced a surfboard modem. This one has had to cycle, but that might be Comcast too. I have a netgear the last time and it worked for three or four years. But I was worried about the speed with everyone on their 5G phones and tablets and all. But then the wife took the kids and ran off with some married pharmacist. The speed is fine now.

    I've had problems with installations of modems in the past, so the fact that this one installed easily is a plus! it was more expensive than I wanted to pay, but the extra features helped me decide on this unit rather than a less expensive one.

    I was looking into replacing my old Modem with Comcast due to reaching 4-5 years of use. The biggest headache I had with replacing the modem with Comcast was reading the serial number. Save yourself the rental fee and purchase one today.

    Great product - security is top priority with all online activity, so having my entire home protected is great. Ditch your ISP and get netgear devices

    Tried an Arris SB8200 first with Cox Gigablast but ended up having nothing but issues with random reboots. I exchanged it for this modem. So far so good, hopefully it will stay that way. I’ve heard similar complaints from other customers.

    Recently my internet provider upgraded their system and I was not receiving my subscribed download speeds. After some research I elected to buy the CM1000 Modem. Easy to install and immediately my download speed doubled from my previous modem.
