Customer Ratings & Reviews

Finally upgrading to 500m internet on cox. I haven’t tested using the direct cable but over Wifi 5, I am still getting 400m over wifi which I am happy.

The modem works perfectly, no issues for the past 6 months!

I would only buy this if you are expecting to have Gigabit internet in the future. It's not cheap, but it works really well and probably better than modems you can rent from Comcast.

Quick and easy install and works great with Cox Gigablast. Cox was the only issue setting it up. Works great and is very fast streaming

Very good Modem, Simple directions made it a breeze to setup and have Internet running in less than 10 minutes.

Customer wanted a solution to not have to pay Xfinity a monthly fee. This works great with xifinty service and great speeds with any changes the company makes in the future to speeds.

Great! I love my new modem. A lot faster than the one my internet service provider has. I also paired it with a Netgear Router and I have no complaints!

I had to replace my old cable modem when water spilled on it. This one is faster and took only a few minutes to set up and have us up and running again. No issues since hooking it up.

I received a call from Comcast stating that my old modem was not giving me the speeds for the service that I am paying for. So I upgraded to this modem. Everything is much faster now.

Good one. Suitable for DOCSIS 3.1 agreement, although it's a bit expensive compared to other models.

Purchased this when we where having issues with Cable company supplied modem. I own a Netgear router also, also purchased from Best Buy a couple years ago, both worhing great.

I am running an Asus wireless mesh and the modem drops connection at least once per day. For me, runs around 100mbs over wifi, with an 18 ping; which is very good. I replaced with an ARRIS SB8200 and it averages around 120mbs with single digit ping and never drops connection, which is better.

Worth the sale, works deliberately. Would recommend to others.

I bought this as an alternative for my router with Spectrum, it's not only satisfying to have all Netgear products now, but the importance increase is fantastic.

This product is demonstrating as promised. It was easy to set up and improved my download speed immediately.

We have at least 30 WiFi devices in use with router. It’s the best we owned. Never any lag, never requires a reboot. Love it.

Fast, and crazy to setup. I like that the dashboard lights are muted, by design, so as not CTO be distracting. However it drops internet far more often than previous two modems, despite being endorsed by Comcast. The reset button is handy but I wish it weren't needed as much which bus why I take away one star.

Works great. I like the idea that I own my own Cable Modem. It works excellent. No issues, or problems. Took me literally 3 minutes to set up and get connected to Xfinity.

I needed to replace an old Surfboard 3.0 modem and found this one on Best Buy’s website as being XFINITY approved. Working well so far and enabling far higher download speeds off the bat!

This modem works so well with our Eero mesh Wi-Fi. It hasn’t failed us yet and it does exactly what we need.
