Customer Ratings & Reviews

I upgraded from SB6121 and immediately my 75Mbps plan was boosted to around 85-88Mbps. With the recent increase from 75Mbps to 100Mbps, I am connecting at around 118-125Mbps. I had to call Comcast to switch my modem but it was quick and easy.

Easy to setup, and great speeds. Highly recommended.

Amazingly simple to setup and it is blazing fast. I only wish it had a couple more LAN output ports.

So far so good, high speeds, reliability, I am happy with product..

I replaced my old Arris cable modem with an updated version of an Arris cable modem. This is very efficient and much faster than the old one ever thought of being. The Arris brand is very dependable...

This product stepped up big time when I couldn’t get my mesh router to work in my new apartment. It’s pretty much plug-n-play with a few minor adjustments for me. I’ve had no issues and it operates flawlessly on xfinity. It’s not the best but it is solid and won’t let you down.

This was an upgrade from an older Arris model. I had been having trouble with my network so decided after 5 years to bring in the newer technology. I got this modem and a new router. The modem is almost exactly the same size shape and works pretty much the same other than the newer DOCSIS 3.1 as opposed to the 3.0 version. It also increased my upstream and downstream channels which you would think makes it better. I really haven't seen that much of a difference as my connection still only has 300 Mbps which is fine for my needs. I would have given this 5 stars if it weren't for the fact that you can't access the modem from your computer any longer if you go through your router. I have everything set up the same as the only devices but now if you type in the IP for the router in a browser you get a time out. The only was to do it is to disconnect everything and use a separate line directly to the modem to view the status and other menu items. Very troublesome when you have to troubleshoot any issues.

Switching to this Modem allowed me to maximize my bandwidth and throughput my high speed Internet provider was putting out. We've had 100% up-time since installation, and runs cooler than anticipated based on prior reviews. Laying it on it's side or standing it up won't affect the performance of this unit.

I have Xfinity and setup was super simple using the online tool. Speeds have been great and I haven’t had any issues after a month of use.

So far this unit has held up strong with no issues. I had to replace my old Netgear

So far this product has done well... I waited for a while to give the review to make sure I was being able to make a fair and honest opinion. This product has been a good one for the price we paid for it and it hardly ever stops working. The only thing I have had to do is reset it possibly about twice a month maybe, because it either goes really slow or just can’t get internet to it. But that’s not a problem. I’m happy!!!

Good modem, does what it needs to do. Why pay monthly to rent, when you can use your own equipment. Cheaper in the long run.

Router has distributed fast speeds and been a solid performer

This a great Modem for the price, it has saved a bunch of money on my internet bill

We purchased one and it didn’t work. We took it back and got another one and It worked very well this time

This product works great with our 4K TV. Very compact

This is an upgrade to my older surfboard, which was limited to 400 mb. With this one I am getting upwards to 900mb and helps with my wireless devices in the house. Only issue was getting reconnected with my internet provider.

With DOCS 3.1 it’s a great value purchase to keep the internet running smooth.

Easy set up. Good value for your money. Would definitely recommend.

I like the connection. Dont have any issues with this.
