Customer Ratings & Reviews

My cable company wanted too much rental for their box, so I bought this one. Speed is great and I've not had any stability issues. It does not have WiFi and only one Gig-Ethernet port, but I used a separate WiFi router.

I noticed a difference in the speed of my service immediately. I wish o would’ve changed it sooner.

I have the previous model that is DOCSIS 3.0 only and it’s advanced interface shows the levels on each channel as well as the corrected and I corrected errors. This model only shows the channels bonded for 3.0. It’s been stable and I like that you can reboot it from the admin interface. It makes it easier to manage remotely if it’s acting up. I’ve used Motorola since before they sold the SurfBoard line to Arris and found them to be the most stable and well performing cable modems. One other plus, this has a physical power button, so no more unplugging the wall wart if you want to quickly power cycle it. I’m using it on Spectrum 400/20 and I routinely test at 440/21.

This cable modem works really well, the throughput speeds are excellent, I do not regret my purchase. The only thing I wish is that you could hanging on the wall.

It's been working well for us as our modem for as long as we've been in this house.

This was simple to set up, allowed us to increase our speed, and has worked like a charm.

I had to buy it when my Charter Modem went out and they could not get there for 4 days . So I went and bought this one set it up that day and has worked great so fare.

Good product, however, I have not gotten the results expected. I still have poor service, at times, even with the highest Comcast internet service offered.

This modem replaced a Netgear modem I purchased in February that kept crashing

Worked nice. I returned it tho got much better price on an open box model

Very easy to setup and works great. I had to upgrade to meet the requirements for my cable subscription. I have owned Motorola Modems in the past without any issues.

Its a great modem for your xfinity/comcast internet services.

I realized I was not getting my advertised speeds from Comcast because my router was a decade old. Now in exceeding speeds that Comcast promises. Don’t pay a monthly rental fee when you can pay this off in 8 months of rental fees.

Works great and spares the rental fee from provider. Would recommend.

Bought to replace a Motorola 24x8 modem, as I upgraded my Comcast internet speed to 800/20...works just fine & had no problem doing the modem swap myself online as I have done previously, with no CSR assistance.

Can’t complain From the description it seems pretty future proof as well.

This worked for the first two weeks then suddenly started dropping connection. I logged into the modem to find no bad readings (there's references online for specific signal ranges to self troubleshoot). That wasn't worth the headache especially since working from home is all the rage nowadays. I went for the new Arris S33 and that hasn't let me down since. I really want to like it and I guess my expectations of a reputable brand came up pretty short. 2/10 would not recommend. I suggest you read up on other sites and forum about this specific model and similar issues. Not a warning, but a big heads-up for would be buyers.

Delivers the connection when the ISP isn't flaky. ISPs are having major issues adjusting, but this modem is a great purchase. Upstream is changing rapidly, but this is a future-proof modem that delivers.

Worked fine once Comcast got around to provisioning it properly - which only took 2 hours. Much better than paying Comcast every month for a rental.

It was easy to setup and was automatic with Comcast, but unfortunately the one I purchased was defective; It kept dropping the internet connection. I returned and opted for a different cable modem.
