Customer Ratings & Reviews

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.

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

Easy ordering online and fast shipping. It was very easy to set up and works great. Will definitely order from Best Buy again!

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 and setup was easy - just call Spectrum and give them the mac number and then reboot.

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.

I was renting a modem/router from Xfinity for years and watched the price go up and up and up. This unit paid for itself in rental fees within a year and I have not seen any slowdown in speed or performance. Very easy to set up, Plug in and one call to Comcast/Xfinity and I was set.

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.

Upgraded from 500 to 800 MBPS internet speed. Old modem was capped at 450 MBPS. This did the trick !! Now consistent at 750-900 MBPS all the time. So far 30 days and still great. Works perfect with Xfinity internet .

Excellent cable modem. Easy to set-up, but you MAY have to call your ISP to add this to your account before you can surf the web. We have Spectrum and they require you to call them to activate the modem. Still, a hassle-free set-up!

Very good modem. Upgraded to this version, and it was easier to say up than the first one was

This is a nice little compact unit that looks great and works well. Easy setup and priced right.

This SB8200 Modem has been working great with Spectrum. This modem is on Spectrum's approved modem list. Upgraded from a SB6190 which was 10 years old.

Switching back to Comcast/Xfinity, and decided I wanted my own modem rather than renting. I ordered Xfinity's "super fast" - on sale for $50 a month - "up to" 600Mbps down, 20Mbps up. It does better than that - I'm regularly getting 700. We had Comcast a long time ago, and the cable was still there sticking out of the wall. So once I'd ordered service on the Xfinity website, I just plugged it in, and pretty soon it was up. Yes, the blue LED status light for DOCSIS 3.1 is very bright, the regular green LEDs are not a problem. I get the downlink blue, up is green. I ended up with a lot of problems getting the Xfinity account to work - three long sessions on the phone and "chat". At one point they put a "block" on the modem and nothing worked. Their mistake. Finally it's all working. Yay! I'm using an old Plume mesh system for the router and WiFi, and a switch for the wired things - and it works well. (Plume is grandfathered in, not subscribed.) In case it's not obvious, this is a modem, not a router. You'll need a router, and I had one. My experience is that things like this eventually have a 1%-5% failure rate, so I got the Geek protection for it. It's only been running a week or two so far. Because we're in an area where the utility can shut off power (or drunk drivers can hit power poles) - wild fires are a real threat in this part of California - I have the modem (and router, and NAS) on a UPS.

Easy to install and has worked fine Bestbuy help with the selection of the product

I had been suing an earlier version of this SB6190 for few months which worked wonderfully, so I decided to repurchase ARRIS modem. It is working perfectly fine and shows different lights (yellow vs blue) depending on internet speed you have.

Set up was pretty simple and it gets the job done. I set it up in an off-campus apartment for my daughter. Saves renting on a cable modem from Xfinity. Solid product.

Provides me with the internet speed that I am paying for where as the modem router combo from comcast barely allowed me 50% of the 400mb/s internet package I pay for. One item of moderate concern is that it does run a little on the toasty side. I had been keeping it in a cabinet in my office and noticed how hot it would get. I placed it out in open air ontop of the same cabinet and it seems to be at a much more acceptable temperature. I have had no service interruption even with it getting hot.

Performs as mentioned in the description and get full download speeds. Small form factor and performance at it's best more

I bought this modem to use with Buckeye Cable to avoid the monthly rental fee. Buckeye will tell you that only certain modems will work with their system and claim they "don't have a list of all approved modems," but I can tell you that this one worked. It will likely require the technician to call during installation to update things on their end. It's been a good modem and has worked well for me.
