Customer Ratings & Reviews

Getting one of these is so much better than paying the cable company for one. We got this to replace an old, slower modem we have, and speed increases were immediately significantly higher than the old one. Spectrum had difficulty setting it up on their end, but not me, and they eventually figured it out - it is approved on their network. Overall, for a device you just need to function, I'm happy with how this one has performed so far.

I am giving the SURFboard S33 only 3 stars. The unit worked well and delivered what I would expect, but after 15 months it died. It has a 2 year warranty and I am currently working on getting it replaced or a refund. However, there only seems to be a support community to contact Arris. Their support page says they have live chat and phone support, but when you go there there is only a link to the community and no phone number.

Easy set up. Working well. We have 8-10 devices connected at any given moment and the speed is great.

These ARRIS SURFboard modems are rock solid. Over the years I have had a lot of different versions of these and the only time they need to be replaced are due to hardware limitations for upgrades and faster speeds. I upgraded my old SURFBoard to this one so that we could get gig cable speeds. It has been running great for the last few months without issue.

Great router. Easy to set up and works flawless. I like the routers look also.

Excellent modem!!! Set it up myself through Xfinity within minutes. Speed is great! Would recommend.

Old modem was going. This replaced it. Very fast, easy set up. Would buy again. Have comcast

Super fast and reliable. Yes cable modem I have bought so far.

This was a perfect replacement for the modem that the Internet Service Provider gives you with your system. It took me about 10 minutes to set it up (including calling the ISP) and it has been running my network with zero problems

Fast as all get out, love the ease of setup and the extra port helps make it future proof

I signed up for 1g internet but my older modem wouldn’t work with that spped so I had to break down and upgrade. Read the reviews on several modems and decided to get this one. A five minute call with th rolling with some dang fast internet. Would do it again.cable company and I’m now.

I bought this to replace the MB8611. I don't regret it. The MB8611 is a great modem but i think it either burned out or something but it's stopped pumping the 2gig internet and dropped to 400mbps. After two comcast techs coming out and verifying all was good i decided to check this one and it's been a dream.

It works great, it works well for Xfinity. I have no issues installing it, just have to call xfinity

Easy set up and no problems so far; it’s been 4 months

Works great. The unit feels warm, compared to the Cable modem I had which was an Arris as well. I returned the cable Motorola gig modem since it kept crashing daily for this unit and so far no issues other than what is mentioned previously.

Excellent modem. You still need to contact your ISP when you buy it. Works well super simple setup.

Looks great and is very fast. Set up was easy..if you are Xfinity like me. Just plug it in the use Xfinity app to put mac address and once it finds it , it will activate and start. At first had a bit difficult with Xfinity that it wasn't able to find it but after exchanging works flawless. Just note you may have to restart a few times and give it time to fully update and get your speed up to what it should be. Will start off slow but after q couple restarts I got faster than my plan speeds! Almost gigabit speed when I am not even paying for it. Much faster than my previous surfboard with docsis3.0. great soft at and had it for a couple of months. Got another for my in-laws and so much faster throughout.

I was having internet issues. I was advised by an associate to upgrade my modem since I had it for quite some time. I made sure this modem was on the approved list for Cox Cable before I made the purchase. The process to switch my old modem took less than 10 minutes. I upgraded to Gigablast and love it! Thank you! I am glad I upgraded my modem!

This router is good. I changed my internet plan to gigabit service and this router is way more than capable to provide that for you since the first jack is 2.5 Gigabit Ethernet port. You just need to make sure you have the speed provided to you by your ISP. There is a second 1-Gigabit Ethernet but, you need to call your ISP and get a separate IP address in order to use that IP. Overall - great modem for a great price!

Easy installation, works like a champ! Don't lease your modem from your Internet provider.
