Speed and Performance

Both the ARRIS SURFboard S33 and NETGEAR Nighthawk CM2000 provide support for speeds up to 2.5 Gbps, which is more than sufficient for most modern cable internet plans, especially for users looking to stream 4K video, engage in high-speed gaming, or conduct heavy downloads. The key advantage of the ARRIS S33, however, is its additional 1 Gbps Ethernet port, which can be used for secondary devices or specific setups. While both modems use DOCSIS 3.1 technology, which allows for faster speeds and better network efficiency compared to the older DOCSIS 3.0, the NETGEAR CM2000 offers a slightly more premium experience with its high-quality design and a more specialized focus on multi-gigabit capabilities.

The performance of both modems has been generally well-received, but there are reports of the NETGEAR CM2000 failing after several months of use, with some customers encountering issues such as blinking lights or unstable connections. The ARRIS S33, on the other hand, seems to deliver more consistent performance in terms of speed and connection stability, although users have noted that it can run hot during extended use, which could impact long-term durability.

Compatibility and Setup

Both modems are compatible with major U.S. cable ISPs like Xfinity, Spectrum, and Cox. However, the ARRIS S33 provides a slight edge in terms of wider compatibility with various internet service plans, especially for users who need flexibility across different providers. The NETGEAR CM2000, while also highly compatible, is tailored more towards users with high-speed cable plans and may not be necessary for users on lower-tier plans who don’t fully utilize its advanced features.

The setup for both devices is simple and user-friendly. The ARRIS S33 features a setup process via the SURFboard Central app, which is particularly convenient for users who want a quick and guided setup experience. Meanwhile, the NETGEAR CM2000 offers a more traditional approach, where users can either activate the modem online or via phone with their ISP. The choice between these two largely depends on personal preference for the type of setup process users are most comfortable with.

Cost-Effectiveness and Value

One of the biggest selling points for both modems is their ability to eliminate monthly rental fees, which can amount to $168 per year or more. For users who are tired of paying rental fees, both the ARRIS S33 and NETGEAR CM2000 present excellent long-term savings. However, the ARRIS S33 is priced more moderately compared to the NETGEAR CM2000, making it a more cost-effective choice for users who don’t necessarily need all the advanced features of the latter.

Despite the higher cost, the NETGEAR CM2000 is marketed as a premium product, which may appeal to users with advanced needs, such as those requiring the utmost in multi-gigabit performance and a more durable design. For users simply looking for reliable high-speed internet without the premium price tag, the ARRIS S33 offers very good value for the money.

Durability and Reliability

When it comes to durability and reliability, both modems are engineered with high standards, but users have reported mixed results. The ARRIS S33, while generally reliable, can suffer from heat issues, which may affect its lifespan over time if used in high-demand situations. The NETGEAR CM2000, although praised for its speed, has experienced more reported failures and reliability issues, particularly after a year of use. Some customers reported hardware failures such as blinking lights and connectivity drops, which detracts from the modem’s overall appeal. Thus, for users seeking a more dependable and long-lasting solution, the ARRIS S33 might be the better choice.
