Customer Ratings & Reviews

I take my network capabilities and quality seriously. I have an Erro mesh network of 4 nodes with 30+ devices constantly connected to my network including 5 Arlo cams (1 4K) XBOX One S, Vivint security, Nest thermostat, several smart lights, phones, computers, etc. all simultaneously connected and constantly being used. I stream most of my content; Youtube, Netflix and do online gaming. My ISP is through COX and I pay for a 100 mbps download and 10 mbps upload and I measure about 350 mbps download and 30 mbps upload. I had an ARRIS DOCSIS 3.0 before and had to upgrade to this because the 3.0 version could not handle to bandwidth that I currently use. This 3.1 device is a necessary link in that chain to make it happen. But you do need to have a need of 300+ mbps download, need a mesh or high-end router and need the bandwidth for multiple devices; all are just as necessary in conjunction with this device. If you plan on expanding your online devices over the next few years the amount you WILL pay your ISP for renting a modem will pay for this device, and this device should last a good 5 years before the next upgrade.

I installed this modem as a User Supplied modem instead of paying rent on the Mediacom supplied unit. This unit is recommended and supported by Mediacom for 200 Mb and up to 1Gb. Plus and Play for the most part and exceeded the 200 Mb during testing. It has run for a month now with no dropped service.

This is my second Arris SURFboard cable modem and I love it. It has been a rock solid performer since it was installed. Very easy to set up with my ISP. My Internet speed tests are spot on with the speeds that my ISP is supposed to provide.

It took a bit of time to get setup. The setup procedure that came with modem did not work for my provider. Once I contacted my provider and get setup. the modem work fine. I was finally able to get the speed I was paying for.

Very easy install and setup for xfinity. It also works well with my google mesh network.

Super fast uninterrupted service. Great upgrade from previous unit.

Works great!! My other modem was failing and would not stay connected. This was easy to set up and has worked like a charm.

I purchased this along with Google nest wifi and I really love this set up I pay for 500 mbps and I get way more than that.

Needed to do an upgrade on my modem. Went from a docsis 3.0 to 3.1. Internet connectivity seems to improved. The new SB8200 is a good purchase. Price was reasonable and performs fine.

My modem is almost 2 years and old with a flawless track record. The unit is sturdy and well built. It is super easy to set up and very reliable. My internet has never been so fast and stable plus the DOCSIS 3.1 is a major bonus. I will be able to keep this unit well into the future.

Very nice modem and small product to reduce the space it takes up. For the price point, definitely would recommend compared to paying my service providers $15/mo for theirs. I feel comfortable to trust the ARRIS to continue providing great speeds and ease of distribution. Great price, great value.

Purchased after experiencing slow internet and constant drops in service with old modem. Now getting max speeds paid for with current internet plan. Modem does not have built in WiFi so you will need a separate router, but doing so will provide better internet speeds and connection than a combined system. Set up is easy to complete with the instructions provided.

This arris modem is perfect it has the right amount of speed given to my router. My upload speed and download speed is much faster. Setting it up was ez and one phone call to Comcast to have them transferred over the new modem into the system. Can't go wrong with this little bad boy is doc 3.1 and its a 10+gigabit modem.

It works no problems. Exactly like my old one just faster. App was easy to set everything up.

I decided to replace my cable modem at the same time I replaced an outdated router. This modem gave me the latest DOCSIS 3.1 technology and provides an opportunity to subscribe to higher cable speeds if I want. Setup was easy. Speeds are good and modem is reliable. I recommend it.

So far so good (since Dec 2025) it works with Optimum services, i haven’t had any issues with Arris products, Thank you for your services!

This was ABSOLUTELY a great upgrade to the previous version. I would definitely recommend it to anyone needing a very fast/reliable/affordable modem. It should b able to handle any reasonable speeds u have, several gbs.

As a word of warning, at the same time that I bought this modem, I also bought a high-end router, so the results may not be the same for anyone else. Now, let me tell you about my network set up. On my home network, there are at least 10 devices (increases to a maximum of 18 devices) that is connected to the network at all times. Previously, I had a refurbished SURFboard 16 x 4 modem SB6182. We had a ton of problems with loading websites and streaming videos on our smart TV. Also, under heavy loads, the modem would get very hot and could not handle the load and stopped working. Therefore, we needed to switch to a larger modem to handle the load. So far, the modem has not had problems with downloading. In fact, we have seen an increase in websites loading. This modem gets warm under loads but never as hot as my previous modem. So, I truly think this modem is worth the price.

So far, so good... Purchased 4 days ago, installed right after I got home. Setup was easy, although I did have to download an app on my phone in order to activate the modem with my internet provider. My previous modem was only DOCSIS 3.0, and Xfinity had upped my internet speed over the last year and half. I was limited to less than 300mbs speed, even though my plan was giving me 800+. BAM! After setup, all my wifi devices are working much better, with fast download speeds. Keep in mind your router capabilities, too. I currently have a TP-Link AC1750, so my 5ghz band can take advantage of the high speeds, but the 2.4ghz band is topping out at 240mbs. That will be my next upgrade.

Very good quality, and dependable. My wife works from home, and it is very important to keep her computer online. I have been using for over a year, and it has not had any issues. I do a lot of online gaming while family is streaming netflix and using tablets with not lag.
