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.

    This is a great replacement for the stock modem that Comcast rents to their customers. Works great with their Docsis 3.0 and ready for when they update to 3.1. Plus you do not have the cost of renting their modem.

    I bought an Arris modem but It had problems and kept disconnecting me from the internet. I replaced it with this modem and so far it kept a good connection and I have not rebooted it for over a month now.

    Got this to replace the modem which had been provided by my cable company. Performance is enhanced following the set up of this modem. The instructions were clear. It took only a few minutes to set it up.

    Purchased this booster when I upgraded my WiFi. Also purchased Netgear modem. Chose Netgear since I already had a Netgear router and have been very satisfied with it and Netgear customer service. The booster was an easy set up and has accomplished what I purchased it to do.

    Instead of renting indefinitely from the cable company, buy one. It doesn't support a land line, but that's an easy and cheaper fix if you still want one. My internet is super fast and doesn't drop like my old modem.

    The connection that I get off of this setup is truly fast. For what I pay I’m getting almost the peek of what internet connection is available. I recommend getting cat 6 cables (Ethernet chords) to speed it all up!

    Great cable modem

    My very old cable modem died while I was in the middle of a virtual conference and the day before my wife was supposed to start teaching school virtually. After a bit of research, I decided on this one. I was able to get it with curbside pickup within about an hour from the time I ordered it. It was very easy to hookup and get connected to Xfinity without needing any information about the modem. The throughput is much better than my old modem and we don't have any signal drops even when we are streaming with multiple devices. I am quite happy with this purchase and can only hope that it lasts as long as my old modem.

    This modem will work with comcast and is a one time thing. Buy once do not pay rental fees! Plus, they cannot updat setting to your modem, so the next router update will not screw things up.

    I upgraded from a DOCSIS 3.0 modem and it’s extraordinary how much faster the speeds I get from this modem are. I use it with an Orbi mesh WiFi system in our home and it’s a great combination.

    There are higher grade modems out there but if you know the limitations of the internet where you live this is a great option for the price.

    This is a great modem, have not had a single issue with it so far. And I just love knowing that the internet/cable company isn't going to be sticking it to me until the end of time in "rent" fees for their modem.
