Customer Ratings & Reviews

Mine only lasted 8 months. Would frequently have to reboot it as it would freeze, would notice it ran warmer than I would have liked. Yesterday it quit completely and will no longer connect to my ISP even after unplugging for several hours to cool. Measured temp at the top of the unit was almost 175 degrees. Hopefully they at least warranty it without issue, as with those temps it is becoming a fire hazard.

I purchased the Arris Surfboard S33, and it has been a nightmare. The modem disconnects 2-3 times a day, leaving all devices in my home without internet for about 2 minutes each time. This is especially frustrating as I work from home, and I've had important calls dropped because of these constant disconnections. To make matters worse, Best Buy refuses to accept a return even though the modem is under warranty until September 2025. They advised me to contact Arris Surfboard directly. Unfortunately, Arris customer service is only available Monday through Friday ( when I am working ). One day when I finally got through, they insisted on troubleshooting the device, which would take more than two hours, before even considering a replacement. The modem’s light turns orange/red, then blinks, and eventually returns to dark green – a clear indication of a modem issue. Even an Xfinity technician confirmed that the cable line is fine and the modem is at fault. I’m extremely disappointed with both the product and the service ( and Best Buy as well). I’ll never purchase an Arris Surfboard product or buy electronics from Best Buy again. This has been a $200 waste of money.

Remember this is a modem it does not provide wifi. Buy a router for that. Plug in, contact ISP, and you now have internet.

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

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.

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.

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.

This modem works great with spectrum, for months I was having issues with the one they sent so I decided to get this modem, now no disconnects occur and my internet works perfectly. The setup was easy, just plug it in to power and the coaxial, then call the cable company.

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.

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.

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.

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.

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.

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.

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

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.

Solid performance so far. Easy setup via Xfinity app, no issues with connectivity once whitelisted. It does getr a little warm, but not hot. Hasn't been an issue so far (about a month online 24/7). Hopefully it lasts longer that the Netgear it's replacing. That thing was great, too, for about 18 months.

Just picked up this week. Was the same price as the SB8200. But this one had the 2.5Gps port (Wanted to get something future proof in case I decide to go GB upgrade) Setup was wonky. Had to call Spectrum. Took about 45 min. Their system wouldn't recognize the MAC ID or SN on the device. And couldn't activate it. Eventually it was able to connect on their end. Modem worked fine with computer hardwired in... but my wireless router (Airport Extreme 6th Gen) was having problems. After some resets and waiting for.. minutes... a lot of minutes, My Macbook finally recognized the green light of the modem in airport utility. Through an extended network to another (AE 6th gen) over 30 feet away through window to the other window. I'm on a 200mbps plan.
