Customer Ratings & Reviews

needed to update old model to obtain higher speeds. everything works well east to set up with cable provider

I am moving from an all in one modem that would cut out all the time, to this beast! To be fair my network setup is about 3x as expensive now, but it was completely worth it. Using this modem, a pfsense router and intrusion detection system, and a unifi AP wifi unit, my network is more secure, more reliable, and actually much faster!

Really good modem for Cox Internet plans, fast, runs a little hot so make sure to have a fan on it if it lives in a cabinet. Typically get 800 MBPS on the Cox 1gig plan.

We had to replace an older modem, and this one is compatible with our system. It was in stock and we were in a hurry to replace the old one. So far it has worked out fine.

Easy to install, great speed, no reboots so far, would recommend to a friend

I was using an old 4x4 SB6121 for the last 6+ years. Chose it because of the price. Didn’t know what I was missing. This one is so worth the upgrade. Two kids streaming vids and both the wife and I working from home, we no long have lag issues. Yes, it is on the more expensive side, but with DOCSIS 3.1 you are good for years to come.

This was a slight upgrade from my last modem that was DOCSIS 3.0 It was easy to follow the instructions using the app, the worst thing about the setup was my ISP entering my modem information wrong multiple times (shocker). It hits gigabit speeds no problem and helped me confirm that my ISP is the issue, not the modem.

Purchased this modem to replace the cheap, $10/month rental provided by the cable provider and to support my upgrade to gigabit internet. So far it's been fast, consistent, and smooth. I connected Google WiFi for wireless access, and the two have been stellar in supporting my desktops, laptops, tablets, and 20+ Smart Home devices. Very pleased with this product.

Easy to setup with just a quick call to the internet provider to give them info off the unit. Then you no longer have to pay for theirs monthly.

Great product works great easy to set up fast internet

Hook up was easy. Result was seamless and very easy.

I had to replace my old and outdated all-in-one wifi modem router. This new modem has greatly enhanced my speed and connectivity with less dropped connections.

Our modem shot craps and they recommended getting our own Docsis3.1 since it would have been 2 weeks to ship a new one. Picked this one and it's been great. Faster. Reliable. No more rental fees. Just remember that you'll have to call in the MAC address to your ISP to get it active. Otherwise, it was plug-n-play. Recommended!

This modem is easy to setup, and provided me with my plans best speeds. Would definitely recommend for anyone in the market for a quality modem that won't give you issues now or in the future.

very good speeds and good quality. easy to set up and use.

This modem is awesome!! I can unequivocally say that after owning/replacing multiple Netgear modems over the course a a year. Setup and install was easy and straightforward. Speeds are what I expected and then some. My only wish is that I had purchased this model brand last time I had to return and replace a Netgear product.

After a year I decided to return my Xfinity router/modem because arris came out with this outstanding modem combined with a netgear Ax6 router made a great combination. First thing I found was outstanding speeds higher then when using Xfi modem/ router. Running now for almost a month and working well. Very happy with new setup.

This is a great modem. The product itself is easy to hook up, although Comcast gave me trouble trying to do so. I have had no issues with it and don't have to restart all the time like I did with the rental from Comcast. In the long run, don't give your money to Comcast and buy this modem with a separate router.

Easy to install, a small size, running stable. faster.

This got rid of my $13 a month modem rental fee. Also, 3.1! So if gigabit comes to my area, I'm already ready for it! I've known the name Arris since I was a little kid, always associated the name with Comcast boxes. And it lives up to it! Works perfectly, nice compact and the white color matches my new Google wifi! Perfect combo imo. Thanks!
