Customer Ratings & Reviews

I upgraded from an older Arris Surfboard modem, and this newer 32x8 Doc Sys 3.1 noticeably improved my online experience . Browser was faster, and response time on Spectrum Web Mail improved, not by much but improved. Down and Up Internet speeds regularly test faster by approximately 17%. I also upgraded my router, and the Arris SB8200 helped my router's efficiency and performance. I recommend upgrading to 32x8, Doc Sys 3.1, if you have an older cable modem, and I recommend the Arris SB8200. It is reliable and stable.

Solid modem for high speed internet connections. Handles my gigabit internet with ease. Small size. Easy to set up.

Performed as advertised. A little slow to boot up but solid as a rock.

Totally fixed my slow internet problems with the ISP’s equipment. I’m actually downloaded the speeds in which I pay for.

After being notified by my ISP that my Docsi 3.0 unit was no longer up to speed, I purchased the Arris surfboard 3.1 unit, which was recommended by the ISP. The authentication process stumbled at the ISP, but with a little help over the telephone, I was up and running in about 40 minutes. It seems to give better speeds, and doesn't need to be rebooted as often as the older modem. When I am streaming entertainment, and the speed is verified, the download data rate is noticeably higher, and the incidence of buffering is significantly lower.

I read reviews that said it ran hot but mine is running cool. Cooler than the less expensive and slower Surfboard this replaced. Right now I'm only at 200 mbps but I the extra channels may have fixed internet connection bogging down during peak times. Whatever, it works, and don't mind the extra expense, as my last modems tend to last a long time. I also have a rental unit and need reliable wifi connection. I also purchased a small usb fan to help keep it cool but really don't think its necessary.

We have gigabit connectivity through Mediacom (Yuck I know, but we don't have a choice), and the connection is great. We consistently see greater than 800 Mbps and the Internet hasn't dropped at all in the last month. It also has a web enabled panel for checking it's health which is beneficial when your ISP is well, bad. Other than that it's modem, contrary to what your ISP may say (*Cough* Mediacom *Cough*) you don't need a degree in Computer Science to install one of these, it has the installation complexity of plugging in a toaster.

Docsis 3.1 rules, wicked fast, easy setup, works great with Xfinity!

In my opinion, this modem is top-notch in performance and is future proof since it well-exceeds current requirements for Comcast (and other) gigabit service. Getting 980 to 995 mbps consistently. Capable of much higher speeds and with 32 download channels and 8 upload channels it outstrips the competition. I chose this one after extensive research of what was available. Pair it with a Linksys WRT1900ACSv2 router and you've got an unbeatable home system.

Works excellent with my new hp desktop is very fast and reliable. Easy to installed.

I’m really Glad I bought this Surfboard very happy with works great easy to setup took me less than 5 minutes Marries your Router with out no problems

Woo, here we are a year later and I forgot I'd gotten it from best buy. I just changed my internet setup and gave this little boy a place of honor on my nightstand with plenty of room for air circulation. If your ISP allows you to use your own modem DEFINITELY consider this one with a router of your choice. SO much more secure than renting a modem from an ISP with your internet. AND while it's more up front for a modem and router ($130? for this modem), you'd pay more than that in one year of renting a modem. So after 13 months I've saved maybe 10-30 dollars, and for every future year I'll save at least $100. CAVEAT: Make sure you know how to install the modem; it's not complicated but you need to know a little about wiring and be willing to be on the phone with your ISP for a bit to set it up. All that said, I wish more ISPs would let you use your own modem, since the only ISP in my area which will allow you to use your own modem is Xfinity.

Bought this to stop paying the bogus Optimum/Altice (Whatever you want to call it) rental fee and to eventually upgrade the speed to 1Gig download without the need for their modem/router in one (NAT Hell). Swapped out the Optimum provided modem with this and within 5 minutes I was up and running through their self install registration webpage. Optimum doesn't show this on their supported modems list but in Edison, NJ this modem is working with their service (Might vary by location).

Works great, had no issues setting it up. I would buy again.

This is currently (early 2021) the best modem that you can get especially considering speed and quality. If anyone is worried about the brand all I can say is don’t worry too much. It should last a long time. I’ve had prior models last 10 years. You should get minimum 5-7 years out of this. It doesn’t have any fiber capabilities but it is future proof in the speed department. It’s a bit pricey still. Hopefully it comes down to a more reasonable amount.

The shopping experience was very fast and easy. They had many modems to choose from. The cashier was kind, helpful and fast. It was snowing and we wanted to get back home soon they got us in and out fast! It is a good product!

Easy to hook up. No problems connecting with Eero. Streaming/buffering issues resolved

Solid purchase to use with xfinity. Why rent a modem when you can buy your own and save money? This modem fit my needs for 600 mbps internet speeds. Speed tested verified and use with my ASUS AX5400. Speed tested both from router and devices and holds speeds. Took me less than a few minutes to setup and works great. Would recommend.

So easy to replace when compared to previous models (router/modems). 1) call cable company with MAC number, request swap out for old modem, 2) follow instructions to power up, 3) connect up to two RJ-45 cables, daisy chaining any additional devices as needed. Cable company provisions it; after about 15 minutes, VIOLA! Done.

The Arris has lasted me throughout the years. It is very fast and I never have any problems from the arris. It has been very reliable so far. This was the second one that I had purchased while having Xfinity as my internet provider.
