Customer Ratings & Reviews

I was very pleased with my previous ARRIS modem so when my internet provider said I needed to upgrade to the 3.1, it was an easy choice to go with ARRIS again. I never ran in to an issue with my previous 3.0 and haven't yet with the new one.

Great product Great purchase Location friendly Good customer service

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.

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.

Router has distributed fast speeds and been a solid performer

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!!!

Works great, 1 gig internet at home is fantastic!!

Converted from cable provider’s rental modem. Was easy with Total Techs help. Was back in business with our 5 tvs and two laptops. Impressive performance.

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

It is indeed a modem that works when plugged in and set up. Instructions QR code doesn’t work so you have to figure it out.

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

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.

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...

Works great. Improved my internet so much. And I love I can lock internet on diff devices through the app

Wonderful! Got it in a pitch after my last stopped working. Easy to put together. I recommend it's not in a sleeping area because the blue light could get bright.

Download speed as promised by Xfinity. Well made although costly.

I bought this Arris SF8200 to replace my old modem. I am technology illiterate. I just connected all the cables and called my internet provider and boom... it's working!

I have a 100mbs plan. The previous modem was an Arris that had 16x8 channels. I've noticed after adding numerous answer TV's, cameras, vacuums, etc that use the WiFi we've had a lot of instances of drop off. TV's buffering and getting kicked off while gaming. This fixed that without increasing my plan.

Works well Previous model "wore out" after 8 years

I'm a bit puzzled as to why this modem only allows me to connect 1 ethernet cord into one of the two ethernet ports. I purchased this to replace my Xfinity gateway. In addition, I bought the Eero mesh network. I was hoping to use one port for the Eero and the other for my computer so that it stood be hardwired and the other devices in our house, TVs, phones, Xbox, Alexa, Ring could connect to the Eero. As it stands, I had to connect the Eero to the 1st port and connect the computer to the other port on the Eero. Then Xfinity had to come in and connect their router for the alarm system which we had to connect to the Eero and connect the computer to the Xfinity router. Mind you, all this after speaking with Eero, Arris and Xfinity. I'm not tech savvy but shouldn't I be able to utilize BOTH ethernet ports? I'm probably going to try to exchange it for a different modem if it's not too late from my purchase date.
