ARRIS S33 Cable Modem Review Fast DOCSIS 3.1 Speeds for Xfinity and More

Description

Compact Design and Build Quality

The ARRIS S33 cable modem immediately caught my attention with its sleek and compact design. It’s a bit smaller than I initially expected, measuring only 5.14 x 1.8 x 4.74 inches, making it an ideal choice for people like me who prefer their tech gear to be unobtrusive. The white finish adds a modern touch, blending seamlessly with other devices in my workspace. Despite its lightweight nature at just 14.4 ounces, it feels solid and well-constructed, with no creaks or signs of cheap plastic. I appreciated how it didn’t take up much space, especially since my desk already looks like a tech explosion most days.

Blazing Internet Speeds with DOCSIS 3.1 Technology

Speed was the main reason I grabbed this modem, and it didn’t disappoint. Supporting DOCSIS 3.1 technology, this modem is a powerhouse that provides speeds up to 10 times faster than the older DOCSIS 3.0 versions. With a 2.5 Gbps Ethernet port and an additional 1 Gbps Ethernet port, I could easily connect multiple devices without bottlenecks. Streaming 4K videos while someone else in the house was gaming felt like a breeze. The low latency performance also stood out during online gaming sessions; there was no lag, even during those intense battles where milliseconds matter. That said, if you’re into multi-gig networking, this modem has you covered.

Easy Setup Process

Setting up the modem was surprisingly simple. All I had to do was plug it in, download the SURFboard Central App, and follow the step-by-step activation process. It took me less time than making a cup of coffee. However, I should note that the modem doesn’t come with built-in Wi-Fi, which might be a deal-breaker for some. You’ll need to pair it with a standalone router for wireless connectivity. Personally, I didn’t mind this since I already had a pretty reliable router, but it’s something to keep in mind if you’re expecting an all-in-one solution.

Compatibility with Major ISPs

One of the key benefits of the ARRIS S33 is its wide compatibility. It works seamlessly with major U.S. internet providers like Comcast Xfinity, Cox, and Spectrum. I tested it with my Xfinity plan, and it was approved for speeds up to 2.5 Gbps without any issues. If you’re considering upgrading your internet plan, this modem is future-proofed for higher speeds. Just make sure to check with your ISP to confirm compatibility before making the purchase.

Positives

• DOCSIS 3.1 technology ensures lightning-fast speeds and reduced latency.
• The compact design fits perfectly on desks or shelves without taking up too much space.
• Easy and secure setup using the SURFboard Central App.
• Wide compatibility with major U.S. ISPs.
• No more rental fees—owning this modem will save you money in the long run.

Areas for Improvement

• The lack of built-in Wi-Fi means you’ll need to invest in a separate router.
• While the 2.5 Gbps port is fantastic, some might find it overkill if their ISP speeds don’t match up.
• The price point may feel a bit steep compared to other modems with similar features.
• It doesn’t come with an Ethernet cable in the box, which felt like an oversight.

Competing Products

When comparing the ARRIS S33 to other modems like the Netgear CM2000 or the Motorola MB8611, it holds its own in several areas. The Netgear CM2000 offers similar multi-gig speeds but at a slightly higher price. It also tends to have a bulkier design, which might not suit those limited on space. On the other hand, the Motorola MB8611 is another excellent contender, boasting DOCSIS 3.1 compatibility and a 2.5 Gbps port. However, I found that the ARRIS S33’s setup process was more streamlined, thanks to the dedicated app. In terms of performance, all three modems are neck and neck, but the ARRIS wins in affordability and ease of use.

Value for Money

Having tested several modems over the years, I can confidently say the ARRIS S33 offers excellent value for money. While it’s not the cheapest option, the combination of multi-gigabit speeds, future-proof technology, and no rental fees makes it a worthwhile investment. I’d recommend it especially for households or individuals who rely heavily on high-speed internet for streaming, gaming, or remote work. If you’re tired of paying monthly rental fees and want a reliable, high-performance modem, this one’s hard to beat.
