Customer Ratings & Reviews

Easy installation and works as expected. No issues.

Connection was easy, speeds are great, compatible with my local internet service provider. No complaints.

If you know anything about modems, you know there was a time when Motorola was the unbeatable kid on the block and made SOLID devices. That's not the case anymore, as I had to turn in my Motorola MB8611 modem under Geek Squad warranty for this Arris Model. I purchased the MB8611 in 2022 and was surprised it had a failure so soon. For some reason, the device just dropped the download speeds to abysmal 0.5 Mpbs levels or lower. Xfinity pushed settings to it and it popped by up for a few hours, then it dropped again, and they said considering how old it was I should replace it. LISTEN TO ME, buy a Geek Squad Warranty with your modem, it will save you the pain in the future and maybe some costs if it fails before it's typical EOL. I picked this since I'm on the gig extra plan with Xfinity and pulled speeds about 900+ Mbps. I recently upgraded to their highest speed consumer plan and this bad boy is going strong and not being a headache.

I bought this to replace a Motorola modem that was randomly disconnecting and dropping service. So far flawless performance and connectivity. I pay for a 1200 megabits plan and I was pulling 1400 megabits down and 40 up on my routers onboard speed test (using standard cat 6 Ethernet cord). It’s a small form factor but gives you two outputs, one 2.5 gigabits and one 1 gigabits, which is nice. As stated, this is just a modem so you will need a router for wifi or to connect more than two devices via hardwire.

Very easy installation. I got it up in running in less than 5 minutes. tthe surfboard app automatically linked to Xfinity! My wifi router connected to the surfboard modem without any issues. Running seemlessly since then!

Only had it for a short while but functions well and get great speeds. Easy setup and love that it gives me an extra port if needed. Only thing I don’t like and it is not unique to this unit or most modems is that the manufacturer does mot allow you to update your own firmware…That is hard to find anywhere. It is also bery compact and easy to fit in most spaces.

The Arris S33 is an improvement over the SB8200. It runs cooler than its predecessor and is less buggy in my opinion. Setup on Comcast was easy and went without a hitch. The case design, smaller size and 2.5 Gig Port with this price point makes this modem a good buy. Performance has been flawless for nearly a month. Now if there were some wired 2.5 Gig routers available to exploit the capability of this Modem.

I have Xfinity internet, and bought this as an upgrade for an old Arris 6141 DOCSIS 3.0 modem. I wanted a DOCSIS 3.1 modem as I'm considering getting the gigabit plan down the road. Setup and activation via the Xfinity mobile app took approximately 15 minutes. Thank you, Comcast, for not requiring us to talk with a customer service rep to activate a modem. I'm getting the speeds rated for my internet plan and have no disconnects or dropouts so far.

Its fast and reliable while being compact and easy to hide. So far so good!

This is a great unit and I think it might be hit and miss being such a new device. I bought this to upgrade from Docsis 3.0 to 3.1 since I upgraded to gig speed internet ( gotta upgrade sometime) while the isp was provisioning the unit it was working great at my former 400 Mbps plan. After the isp upgraded the unit they began to upgrade my speed to gig internet. After that the unit was not responsive. It would not pull up web pages however the isp saw it as fine. It is still a new device that may need another firmware upgrade to truly make these plug and play (note date : 12-17-21 as the trial date as they may update it soon). Other than that I truly see this as a great unit. Ultimately had to return it and opted for the other Arris 3.1 unit.

Retired an ARRIS SB6183 (solid modem) and got the S33. PROS: - ARRIS, solid company - Lastest DOCSIS 3.1 modem - The footprint is a bit smaller than 6183 with great looks - x2 ethernet ports = 2.5 Gbps and 1 Gbps CONS: - $$$, bit high on the coin but get it on sale - 1 status LED, if your're used to multiple ststusLEDS, you'll probably won't notice it down the road. Mines turned off. - Nag screen when accessing the modem config to download the ARISS app, not necessary - Gets a bit warm

After upgrading to a Unifi Cloud Gateway Max Router and pairing it with this Arris SURFboard S33, we were able to achieve the internet speeds we are currently paying for, which were previously out of reach for our old Netgear CM400 modem/Google Nest router combo. The upgrade has been extremely successful, and we are now fully utilizing the higher internet speeds that we purchased. It's not the fastest/newest modem but as far as standalone modems goes it seems to be excellent. For people looking to upgrade their modem and wifi router, some of the wifi 7 router options in the store are rather expensive compared to a Unifi Cloud Gateway/Unifi Wifi 7 Access Point combo.

The modem is very straight forward. The only part anyone needs to worry about is whether it is compatible with their ISP. Ensure your speed max is exceeded by the modem. That is the only qualification required. I would recommend an Arris router then as well. I bought an Asus and they don't really speak to one another. My 2.4 gig stuff doesn't necessarily talk to the router either. It just gets found and connects because I made the profile the same as my former Spectrum stuff. I will say that the device could possibly use a little more of a footprint, and is close to needing a fan, as it gets very warm in service.

Great modem. Bought this to replace the Cox Panoramic wifi router. Tired of renting used equipment that would have to be replaced yearly. The speeds are reliability with this modem far exceed what we were getting before. I have added a mesh system to this modem and have been extremely happy with the results.

Great modem. Works very well with Cox. No connection drop. I strongly recommend it.

Easy setup, really was plug and play with my Decco mesh network.

Excellent product with seamless setup with Mediacom.

Super fast with no problems. Dual LAN connections make managed networking easier. Highly recommended. Has 10G and 1G connections. It does get warm so cool area recommended for installation. It will last longer if it keeps cooler.

Had a unit from another brand breakdown and needed a new modem, wanted to try this brand out. It has been lightning fast and consistent in its performance, with easy setup and a lovely small footprint that makes it so easy to place. 5*

Installed and works great! Connected quick. Would buy again.
