Customer Ratings & Reviews

this new version is faster than the old one it is very easy to set up. very small does not take much room.

Easy to set up, works great! Have not have any problems, and it saves us a ton of money each money vs. renting it from our internet provider.

Choose this Arris Modem over many other options. Compatible with my Comcast plan and light is at a minimum (previous modem was like lit like a disco ball). Does run a bit warm but NOT overly concerned about that. Easy to set up.

We bought this modem after Comcast boosted our speed, and we weren't getting the subscribed speed with our old modem. The speed increase with this modem was quite noticeable. The modem was easy to install and has been working perfectly.

When I decided to turbocharge my internet experience, the ARRIS Surfboard S33 was my chosen steed. Here’s why it’s become an integral part of my digital life: Futureproofing at Its Finest: The S33 isn’t just an upgrade; it’s a futureproof fortress. With the capability to handle speeds beyond 1 gig, it’s like strapping a rocket booster to your browsing. Who knows when we’ll all be hurtling through cyberspace at warp speed? The S33 is ready. Setup Simplicity: Setting up this modem was smoother than a freshly paved highway. A quick call to my ISP to announce the modem swap, and voilà! The S33 slipped into place. No tech acrobatics required. Compact Marvel: The S33’s profile is akin to a minimalist sculpture—small, sleek, and unobtrusive. It doesn’t hog precious real estate on my desk or in my tech corner. A nod to efficient design. Specs That Sing: Under the hood, the S33 boasts specs that align with my needs and my ISP’s offerings. It’s like having a tailor-made suit for my internet requirements. No excess baggage, just pure performance. Steady as a Lighthouse Beam: Since upgrading both my internet plan and my modem, the S33 has been my lighthouse of stability. It guides my connection through stormy digital seas, ensuring I sail at my max speed of 1 gig without a hiccup. In summary, the ARRIS Surfboard S33 is more than a modem—it’s a gateway to digital velocity. So, if you’re eyeing the horizon for faster speeds and smoother surfing, consider this compact powerhouse. Your browsing sails will thank you!

Solid choice for a DOCSIS 3.1 modem. Sadly I have Xfinity/Comcast service and was using a SB6183, which worked great. My package was upgraded to their 400mb service and the old modem couldn’t support the speeds. The setup on this was easy and has been working as expected since install. This modem allows up to 8 upstream channels to be locked which helps the modem stay connected even with ingress present on a node. For the folks that care, this modem offers more detailed logging within the webui, also has a restart button too.

Almost plug and play, setup is very easy with the manual! Significantly faster than the modem provided by my ISP. Has increased my internet speeds by 10%.

Had to replace my old ARRIS Optimum modem. This one works beautifully. No regrets. Just remember to call your service provider to activate it so you have the full features. Just plugging it in will give you service but you will notice it's slow.

Upgraded from old school Moto that was capped out @130MB. Super easy install(Spectrum), took no more than 5 minutes. Capable of insane speeds, definitely future proof. Small, sleek, attractive, and led isn’t too intrusive. Very pleased!

The speed is definitely quicker than my old modem. The reason I am not giving 5 Stars is because I don't know if I sometimes lose Internet connection from my ISP, modem or computer.

This DOCSIS 3.1 modem works exactly as advertised. I've been using Arris modems for the last 7-8 years, and I've never been disappointed. The speed that comes across this modem is excellent. My router doesn't bottleneck it and I'm very happy with how my setup works using Cox's giga-blast internet service. The S33 modem just works. I use a standalone Netgear Nighthawk gaming modem to push wifi and when we lived in a house we used a Netgear 8 port gaming switch to push internet across cat6 cables to all of the fixed devices, such as TVs, DVD players, and computers, and my SB1608 had no problem handling that internet load. I can't wait for our new house to be built, because this should push much faster internet to those same devices.

This modem was bulletproof. And it is actually up for sale on Facebook marketplace because I have switched to a different tv service. Works great with COX. https://www.facebook.com/marketplace/item/3976752542637782/

Very easy to set up and is working great. So far, no connection issues.

The modem is great, routinely connecting somewhere between 16 - 1200Mbps over Xfinity based on daily bandwidth testing from my security appliance, but the slow speeds seem to just be Xfinity's regular hiccups and problems. Setup took about an hour to complete, but it was about 15 minutes swapping in the modem/re-running the new cat6 cabling instead of my old 5e. Adding the modem via the Xfinity app added another 30-45 minutes before I was passing traffic, but that also appears to be an Xfinity issue.

Great upgrade streaming is faster, uploads and downloads, even in the basement.

Installation was OK for a device that rarely requires attention. i recommend that you D/L the manual before you switch to the new modem. Also copy down the MAC before you bury it in your system. You'll need it to register the device wiith your internet provider. Performance is great!

We replaced the Comcast high speed modem/router with this modem and a separate router that gives us 2.5, 5, and 6 gig options with it picking the best for each connection. No regrets at all. So much better connectivity and speed. No more dropped chats while my son gamed or lost internet connectivity and it reaches our entire house unlike our old setup. Get it you won’t regret it. Great modem.

Works. Fast, Easy to use. On the expensive side, so if you dont need 2.5 Gbps, maybe go with a cheaper model.

Love this mode...!!! Its been years since my last modem and it was time for an upgrade. This modem is extremely easy to set up, is extremely fast and has a very stable connection! Very pleased with the purchase!

Time to upgrade my nearly 10 year old cable modem. This upgrade is capable of 2.5 gps soni did upgrade my Xfinity the same speed. And it did not disappoint
