Customer Ratings & Reviews

We upgraded from a 3.0 to this 3.1 and our internet speeds almost doubled so I highly recommend this!

Fast and stable speeds. Works great connected to my wireless router to feed all of my connected decided reliably.

The Surfboard is newer than my previous model and upgraded to get higher speeds. It took about 10 minutes from the time I was home to the time it was connected and working on my system. Set up was so easy. I would recommend this low-profile powerful modem. Cheers!

Works flawlessly with Spectrum 1GB service. Was able to get it setup quickly and it cut my ping in half, AND increased my internet speed from ~600mbs to nearly 900 with NO other changes. This is far superior to the modems Spectrum sends. I upgraded to this one because it is one of the very few listed as compatible with Spectrum that does NOT have the Intel PUMA chipset.. with its known issues. So far this was a very good move.

Could not be more pleased with this modem. Very easy set up. Paired with Nest mesh wifi. Pulling great speeds, and got on sale as well.

Lightning fast, reliable! Originally bought to replace my existing same model as I thought my old one died. Turned out it was Comcast outside line. My original continues to rip along flawlessly.

Great Modem. I have my own wireless router so I had no reason to purchase or rent the panorama wifi gateway from my provider, COX. If you buy this you will need to contact customer service and have the MAC address and SN of the device ready. These are listed on the device but also on the cover of the owners manual to make things a little easier. Once CS has this information they'll be able to allow your modem on their network and once it reboots, it might reboot again if it needs any firmware updates. Not that this is for DOCSIS 3.1, so works for Gig speeds; you won't need this for any lower package, a 3.0 will work for that. This guy's not cheap, but it's the best you can buy IMO.

I was told by my ISP I needed to upgrade my modem, and since I use a mesh wifi system, and I don't need telephony, all I needed was a reliable modem, and this was the best deal I could find.

An amazing modem with incredible speeds! I have connected to an Ampli Alien router and let me tell WOW! Most folks who not up to date on all the Wi-Fi 6 business will miss on exactly what modem is capable of. A 3.1 DOCCIS Modem must be used with a WI-FI 6 capable router in order to get your 1 giga bit speed’s assuming you’re paying for that level. Unfortunately, I had to return mine because my modem’s in my bedroom connected to my gear the thing puts out a lot of light, I found myself putting it in a shoe box every night LOL! That being said highly highly RECOMMENDED!!

Only had this for about a month, but so far, I have had fast internet, with no issues what so ever. My speeds are noticeably faster; however, I also upgraded my internet download speed at about the same time that I switched to this modem. I have not used the second ethernet port on the back, all items are connected wirelessly through a separate router. Heaviest traffic at my house is two HD movies streaming at once with 6 cells going at it with games/social media, 2 working laptops and 5 other wireless devices that either download music or news. No issues everything runs top notch, my Xfinity download package is the 800 MB

Rather than pay a monthly fee to rent a modem from the cable company, and because I wanted fast, reliable uploads and downloads, I discussed my options with the Best Buy sales folks, read reviews of products by various companies, and selected this model. This unit is certified for use with my internet provider's system, and was very easy to set up. I purchased a separate wifi transmitter; and since it's plug and play, just let the modem do its thing talking to the provider's system. I did need to consult Best Buy staff plus the provider's staff with questions; they walked me through the process. Actual time to set everything up and connect was only about 20 minutes. Knock on wood, it's working fine, with only a few brief interruptions in connection which I assume was caused by the cable company's side of the system.

The set up was easy. It’s the internet provider that makes the process difficult. We were changing out the internet provider’s modem. This is a very suitable modem for the internet package we have.

Installation was a easy although I had to call the cable company so that they can set it up on their end. The service has not dropped and the steadiness of the modem has been great. I have this paired with a Google Mesh. This was a great buy for the price. It was my own "non research" but the two ethernet connections in the back were more about connecting it to two separate routers and not the same router.

Recently switched a mesh system so needed a modem without an integrated wifi router. This modem was super easy to set up and works perfectly with our new TP Link mesh system.

This is a great product, easy to install easy to connect with My Spectrum Internet with Spectrum customer support. Wi-Fi is faster than having no issues. Would highly recommend.

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

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

Beat Surfboard out there. Handles high speed with ease with 3.1 DOCSIS

Love it. Easy and works well. Covers a wide range throughout home.

ARRIS - SURFboard 32 x 8 DOCSIS 3.1 Cable Modem My previous cable modem died and I was forced to get a replacement. I decided to try to future proof my purchase going with a DOCSIS 3.1 modem even through that standard isn’t wide spread yet. This modem has 2 RJ45 input ports but unless you have 2 IP’s supplied by your internet provider you can’t use both input ports for faster speeds and bandwidth. The speeds I get max out the tier of service I’m presently on and with the ability of going to a higher tier in the future I should be set for a while. The modem does get hot, mine is in the basement so it should be too much of a concern. I might add a computer chassis fan for cooling since that is what probably caused my old modem to fail. I’m a firm believer in separate modem router setups. The modem/router combo units can supply better use of space but also less flexibility and less ability to upgrade in the future without replacing the whole unit. Overall I’m satisfied with the modem but it is over priced.
