Easy setup and works as it should. Approved for use with Cox so comes online smoothly. Seamless with eero

This is a great modem. Was super easy to install, minimum footprint and has worked seamlessly with my eero mesh router with speeds pretty reliably close to the 1GB I'm paying for.

Super fast and easy set up and that also describes the performance. Giving me blazing fast speeds along with my Google Mesh devices. Highly recommend. Very happy

Well here we go Here's the Arris S33 that I exchanged that Motorola for If you go to the review of the Motorola that would be the competing side you can see what I mean about the Motorola probably having a locked bootloader If you want user friendly connectivity I'd recommend the Arris over the Motorola If your ISP is listed on there and you're you know just gung ho about getting the Motorola then go for it I was just trying to switch teams from the 8200 since the Motorola 8600 was its counterpart last generation and I didn't realize it most likely has a locked bootloader and that's why it only works with certain ISPs Keep that in mind there's a price difference I believe the errors is cheaper It runs great I never had a problem with the original and any reason to stray I just wanted to try it Even if your ISP is listed on there I think Cox and a couple others around there you're better off just getting the airs cuz it's going to play nicely with those as well and if you ever move and you have to switch ISPs you're still going to have a modem that's going to work with essentially anything Think of it like having an unlocked bootloader on a phone.No compromises and performance. I was just curious ARRIS

Love the speed I got when booted up. Due to this model having heat issues(no vents on both sides) I'm having to shut down my modem every night so it can cool off. Arris is a good brand modem. I have had previous models but never one like this. As a rec ok mmandation if anyone does but this model is to plan to purchase a mini fan. Those like they have in deck top computers to cool out modem down while in use. That's fan is my next purchase.

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!

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

This modem is very small. I lead with that because the cable it’s attached to topples it over unless I book-end it. That said, it is easy to set up and it is very fast. It works well with my mesh router system and saves on monthly rental fees. I upgraded from my old still working Arris because this one was compatible with Xfinity, my new internet provider. The app is easy to download and updates are automatic. There are other features, but I will leave those to the techies to highlight. Good value for the money.

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.

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

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

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 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.

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.

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.

Love this modem. Have had zero problems with it. It is already ahead of the curve in terms of what most ISP’s even provide yet. I use this with a 1 GIG internet service and it is flawless.
