Customer Ratings & Reviews

Easy setup and getting speed as indicated on the box.

This modem was super easy to setup and seems to be very reliable. I highly recommend it.

I get the expected speed out of this modem and it is indeed compatible with Xfiniti's DOCSIS 3.1 requirements. This is exactly what I needed since I already had a router from when I lived in a building with centralized switches.

I don't buy modems often but when my last one failed, I decided that I should upgrade to one that supports faster speeds. I haven't had any issues with this and it works as advertised.

Excellent product. I was paying $300 a year Renting A box. Now I'm saving that. Thank you.

This modem does what was advertised. It allowed me to use my Spectrum 1 gigabyte internet no problem instead of renting their own hardware.

Easy to connect. I wish it was a bit cheaper but works well.

This cable modem was straightforward to install. My only problem has been getting bonding on the upload channels. After troubleshooting the problem with Mediacom, I believe the problem is with the speed of my internet service, not the cable modem.

A fast modem - powerful too. If you have a great WiFi system (like Eero, etc.) you'll have great covereage and high-speed internet access!

replacement per Xfinity notice...works well, reasonably easy to set up/had to call xfinity but ok experience; good price, nice people at best buy to help

I was recommended this router from both the salesperson and my high end audio dealer as being a very quality product. This unit has performed solidly since I put it in. Combined with my Asus router, I have a much better internet experience than with the old cable modem/router I was using.

Easy set up with Xfinity. Works very well. Gives you the speed that Xfinity gives you.

Originally bought this to not have to rent modem from Comcast. If you are currently renting, stop and buy this! I have switched to a local ISP fiber, so no longer using, but installed this at a family member's house instead and working swimmingly.

Came recommended by my cable company. Was priced right and easy to set up. User manual was a bit lacking in information.

With my enternet provider having 300mb this router can keep up with multiple streams and gaming devices no complaints here

I bought this cable modem because I already have an access point/router that is still working really good and it is half the price of the cable modem combo (wireless and cable modem). My ISP no longer supports my old cable modem, and it frequently drops wireless wifi coverage at home, and even the wired connection is also slow. I originally bought this same cable modem at Amazon, but it was defective and cannot be configured properly. It was a returned product from a previous customer, and I returned it too. I need a new cable modem badly and found out that my local Best Buy has the same item in stock at the same price as Amazon. I was able to pick up the new cable modem the same day and configured it immediately and it worked properly. I was very happy with the new item from Best Buy.

Great alternative to renting a modem from Comcast if you're ordering service over 600MB/s. You'll have to call your ISP to ensure they deactivate your old modem and activate the new one. Connected to TP-Link Deco, works like a charm!

I upgrade the Xfinity to a 900 Mbps plan and changed to this modem. Wired connection provides full speed and wifi6 wireless router has more than 600-700 Mbps at the close. Saved monthly model rental fee

Bought this modem as an upgrade for an older surfboard modem. The increase in speed and stability in my connection was remarkable. I am consistently getting about 10% more speed than advertised by my provider. Would highly recommend as an upgrade from your existing hardware.

Upgraded from an older Surfboard, which lasted many years. This model easily achieves my rated internet speeds (both downlink and uplink) and should last for several more years of internet speed upgrades.
