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.

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).

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.

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.

Good product fast and reliable helped me save money instead of renting from cable company

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.

The decision to upgrade an existing Comcast cable TV and Internet service also required replacing the preexisting cable modem with a newer, up-to-date model that had been certified to work with Comcast's services. Since the previous cable modem had been an ARRIS model that functioned reliably for over ten years, this newer ARRIS SURFboard 32 x 8 model was selected as its replacement. This unit was relatively easy to install and interfaced smoothly with the upgraded Comcast service once the new modem had been remotely initialized by the service provider.

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.

More expensive than it should be in my opinion, but even then it pays for itself in less than a year since Xfinity wants $180 a year for the privilege or renting one of their modems. Even if it only lasts 5 years you will have saved almost $800. And it may last longer. The modern is OK. Not the best and definitely should have 2.5 Gig Ethernet ports for the price, but if your internet is less than Gigabit speeds you will never notice. It’s a proven design having been around for many years, and this version is DOCSIS 3.1 compatible (again, perfect for most users unless you require gigabit internet or higher).

High quality product with easy setup, clearly written setup steps, and online support should it be needed. Also supported by the local Cox Cable Company on their Internet Networks. This also saves money for you over all the years this product will be utilized Vs paying $10.00 monthly for the same product from the local cable company.

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

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.

Works great ... Better than Xfinity one that gave off an odor as it whined LoL

Arris Surfboard Modem was easy to set up. It has performed well.

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

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.

The ARRIS SURFboard SB8200 is a high-performance cable modem with DOCSIS 3.1 and 32x8 channel bonding, delivering reliable gigabit speeds for streaming, gaming, and more. Its sleek white design is compact and stylish, and it’s compatible with major providers, cutting rental costs. Setup is easy, but confirm your ISP supports DOCSIS 3.1.

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.

Excellent performance! Super fast, and small too! Rests comfortably on my desk. Sometimes i forget it's there!
