Very good unit.. Not sure about the cost but so far this is my third Arris modem over a few years.. I don't kno about long-term usage tho.. And Arris wouldn't offer me anything but paying more for warranty and phone support

The ARRIS SURFboard S33 has been an excellent upgrade for my home network. If you’re running a high‑speed internet plan or planning to move into multi‑gig speeds, this modem is absolutely worth considering. Setup was incredibly simple—plug it in, activate it with your ISP, and it’s ready to go. The whole process took only a few minutes, and the modem connected without any issues. Performance is where the S33 really shines. Speeds are consistently fast and stable, even during peak hours when my previous modem would slow down. The 2.5Gbps Ethernet port is a huge advantage for anyone who wants to future‑proof their setup or take full advantage of faster plans. Streaming, gaming, video calls, and smart home devices all run smoothly with no drops or buffering. The compact design is another plus. It doesn’t take up much space, runs cool, and stays quiet. Once it’s set up, it just works in the background without needing attention. That reliability is exactly what you want from a modem. If you’re renting a modem from your ISP, the S33 pays for itself quickly. It’s a strong, dependable choice that delivers the speeds modern households need. Overall, the ARRIS SURFboard S33 is a fast, stable, and future‑ready modem that I’d easily recommend.

Overall a solid modem. Occasionally I will need to restart both this and my dedicated router due to connection drops but I belive this has more to do with my ISP than the product itself. YMMV

Well, I bought this in January and now it's September and it's not working. This is the first one I have had malfunction. When it worked it was great. Now I just have the blue solid light of malfunction and no internet.

Best modem for the price. No dropped connections, auto updates. You cant customize it or go into the firmware. But it works fine.

Setup was super easy and it’s been working great so far. I haven’t had any issues in the two weeks I’ve been using it. It’s also noticeably smaller than my last modem, which I like because it takes up less space. The only thing I’d change is maybe having a few color options, but overall I’m really happy with it.

I recently purchased the Arris modem and I am beyond impressed with its exceptional performance. Not only does it deliver lightning-fast internet speeds, but its sleek and compact design makes it a perfect fit for any modern household. Setting it up was a breeze, thanks to the user-friendly interface and clear instructions. The reliable connectivity it provides has completely transformed my online experience, enabling seamless streaming, gaming, and browsing without any interruptions. With its robust security features, I feel confident about the safety of my network. The Arris modem has truly exceeded my expectations, and I highly recommend it to anyone seeking a top-notch, dependable internet solution.

I had to replace my modem to accommodate 1 gig internet. My previous modem was an Arris Surfboard so I went with this one. It works as expected and was easy to set up.

Set up was a breeze, and it was quite the upgrade over my Comcast supplied equipment. Notice will increase in overall speed.

I needed a faster modem as I upgraded service with Cox. I've used the Arris Surfboard products for years and had success with them, so a no brainer to step up to the next level. Checked with Cox to find all the compatible devices and this surfboard met the requirements and was easily the best value. Easy to connect/swap out forbthe old device. Didn't get it to automatically register with Cox, but that was a Cox issue, not a Surfboard issue. Had fast speeds and no issues since using it.

This is a perfect upgrade for those who want their own modem over what their ISP provides, as it’s both a solid piece of equipment from a model line known for quality, and a marked improvement over previous models on an aesthetic front. So about the modem itself - setup is a breeze and the unit is simple to manage. The worst part about setup, for me, was needing to contact my ISP to provision the equipment; with most providers, you’ll want to use the yellow ethernet jack as it’s the fast one (2.5 gbps versus 1 gbps). Make sure you tighten the coax line with a wrench to prevent as much interference as possible. For current Surfboard modem users, espexially those who have 6000-series modems like myself, the most welcome change is the connection indicator light. Instead of four bright blue and white lights that can light up a room, you get a single indixator that flashes yellow as it connects and stays a dim blue when it is connected. The biggest thing you should do with this modem as soon as you physically set it up but before you contact your ISP to provision it is to log into the modem information page so you can set an admin password for those pages and mitigate any security risks. So why did I buy this, you might ask? My ISP upgraded speeds from around 300 mbps to around 1 gbps. With this upgrade, I needed to replace my aging modem as it wasn’t fast enough to keep up and would drop connectivity. The modem previous to that would also drop connection when my ISP did another speed increase ages ago. In closing, is this modem worth it? Yes, as it’s likely to pay for itself at least twice over during the time you’ll own it. Also, pick this one over a model with gigabit ports as you’ll be able to support faster routers, and therefore faster connections. And if your ISP has you on a data plan faster than 1 gig, invest in a router with a 2.5 gbps WAN port so you can take advantage of that speed.

The Arris S33 is capable of running two networks (1 up to 2.5 gbps, 1 up to 1 gbps giving it the capability to run two separate routers. It’s DOCSIS 3.1 compliant, small footprint, properly ventilated incompatible with major Internet providers. Set up is easy especially if you already have a router that can handle 2.5 GBPS. Note; make sure it is peared with a router that can handle speed provided by your Internet provider. This is my second Arris. First one worked flawlessly for years. Purchase the second one to handle of a new Internet plan. Best Buy made this purchase easy.

Works great and was easy to hook up. Was a nice upgrade from my older modem.

super easy to set up, and the longest part of the set up was the cable company provisioning. So far, it has worked flawlessly (as expected). I especially like the lower profile it has compared to my previous modem (Netgear CM1000) and the simplicity of its looks.

This modem connected quickly and has worked flawlessly. I am in a Cox Communications area. I have not seen the high temperature concerns that some reviewers have mentioned. That feedback had originally pushed me to buy the Netgear CM3000. I could not get that Netgear modem to work reliably, so I returned it and went with this Arris Surfboard S33.

Recently upgraded my Xfinity internet plan to the Gigabit Extra (1.2 Gbps) and needed to upgrade my cable modem as well. Did some research and found that this is one of those compatible routers and I have always used Arris cable modems and never had any issues. Overall, I was able to contact Xfinity and register the device and so far it has been working good.

Works great. Was easy to set up and connect to Xfinity

The Arris S33 was very easy to set up and has been performing great. I had researched various modems as options for upgrading my existing Motorola modem and I was looking for compatibility with Comcast, quality performance, ease of setup, price and it's ability to handle future service upgrades (speeds). The Arris S33 has it all. I highly recommend it.

I bought this to replace a rented Cox panoramic wifi modem/router combo. The Cox unit had poor wifi coverage and the modem did not play well with my mesh wifi system. Since swapping in this modem, everything has been a dream. Consistent high speeds and no wifi crashes. I highly recommend this for anyone looking to ditch the Cox panoramic wifi system. Just remember this is only a modem so you will need a wifi router too.

I’ve had the ARRIS SURFboard S33 for over two years and it’s been rock solid. It delivers fast, consistent speeds and handles multiple devices without issues. Setup was simple, and I haven’t had to think about it since plugging it in.
