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.

    I changed out my leased cable modem and purchased this modem. Best decision ever! Super fast and has made a difference in my streaming. I have over 25 connected devices on WiFi, including surveillance cameras, smart locks, tablets, printers, computers, laptops, etc... I pay for 400mbps of speed and with this modem, I’m getting more than 400. No delay in streaming either.

    Very fast. A bit spendy. A bit of a pain to set up. Haven't had to reboot for the past several weeks we've had it. I actually would have gone with a different Motorola docsis 3.1 modem because it had 3x the top speed of this unit. But I don't even have 1 gb internet right now, and that should be plenty fast for the foreseeable future. OK then.

    This Docsis 3.1 modem was a great price. This was purchased to keep up Xfinity service that keeps getting upgraded all the time. The unit will handle a Gig service

    I loved it while I had it but I had to return it because I got fiber Internet put in and they don’t use it. It was really powerful and did a good job and you can’t go on purchasing this.

    I purchased this modem to use with Cox cable internet service currently at 300 mbit claimed speed. My 4 year-old docsis 2.0 modem could only do 33 mbit. Changing nothing else, this modem tested at 330 mbit down and 35 mbit up. You will have to register it with the provider. In my case, this saves me $10 per month modem rental fees so it will take me less than 18 months to be money ahead.

    Love this modem. It does everything you could want from a modem. You'll want to check your carrier supported list (they vary on which channels they use apparently and has to match the carrier to get the full bandwidth out of it). Only needed to spend the premium prices if you are using Comcast higher bandwidth services, but this modem is blazing assuming the carrier can deliver it to the modem.
