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.

    Simple to set up, worked with xfinity’s online authentication. Xfinity recognized the new device and configured it without having to call in, all done through a browser. Any time I don’t have to call them is a win. So far, it’s been rock stable.

    I've had zero issues with it. Called my cable company and they had it up and running in no time. I'm really glad to have gotten Docis 3.1 I feel "future proofed" for many years.

    We love it! You can tell the difference. We bought this because we wants to stop paying $10/month to Comcast for using their modem. I wish we bought this sooner. We can finally get the speed.

    Was paying for 100G download and was only getting 15-20G with the modem Xfinity gave me. (Plus I had to pay $10/month). I got this and am up to 75-80G wirelessly on my phone. Worth it.

    Most modems with advertise that they can handle gigabit speeds but you really need Docsis 3.1 to get that speed consistently. This modem has a better processor than the Arris Docsis 3.1 modem.
