10 Best Modems 2026 in the United States

The ARRIS SB8200 Cable Modem is a powerful device designed for users who need fast internet speeds and reliable connectivity. Its use of DOCSIS 3.1 technology means it can offer speeds up to 10 times faster than the older DOCSIS 3.0 standard, making it ideal for heavy internet use, such as streaming HD multimedia and online gaming. The modem is compatible with major U.S. providers like Comcast Xfinity, Cox, and Spectrum, ensuring broad usability.

With approval for speed plans up to 1 Gbps, the modem is well-suited to handle high-speed internet packages. It features two 1-Gigabit Ethernet ports, which allow for the connection of a Wi-Fi router or other wired devices, providing flexibility in setting up home networks. However, it's important to note that the ARRIS SB8200 does not include a built-in router, so you'll need to have or purchase a separate router for wireless connectivity.

Setting up the modem is straightforward with the SURFboard Central App, and support is available through live chat and phone. One of the selling points is the potential cost-saving benefit, as owning the modem can reduce ongoing rental fees from your ISP. On the downside, the modem lacks telephone ports, which might be a limitation for those who need this feature for their home phone service. Despite being released in 2017, the SB8200 remains a popular choice in its category, with positive reviews highlighting its performance and reliability.

The NETGEAR Nighthawk Multi-Gig Cable Modem (CM2000) is a solid option for users looking for high-speed internet from major cable providers like Xfinity, Spectrum, and Cox. It supports cable plans up to 2.5Gbps, making it ideal for heavy internet users, gamers, and streaming enthusiasts. The modem is built on the latest DOCSIS 3.1 standard, which ensures faster and more efficient data transmission with 32x8 channel bonding and 2x2 OFDM(A). This tech enables high-speed connectivity and reduced latency, which is great for high-demand tasks.

One significant advantage is its compatibility with any WiFi router, allowing flexibility in choosing a router that meets your wireless needs. It includes a single 2.5 Gig Ethernet port which provides a robust wired internet connection for devices requiring high-speed internet. However, it lacks multiple Ethernet ports, which might be a downside for users needing to connect several wired devices simultaneously. Also, it does not come with built-in WiFi, so an external router is necessary.

The modem offers potential cost savings by replacing rental equipment from cable providers, but it is not compatible with Verizon, AT&T, CenturyLink, DSL providers, DirecTV, DISH, or any bundled voice services. The CM2000 is a high-performing modem best suited for users within its compatibility range seeking top-tier internet speeds.

The NETGEAR Nighthawk Cable Modem with Built-in WiFi 6 Router (CAX80) is a robust option for anyone seeking a high-speed internet connection, especially for users with cable internet plans from providers like Xfinity, Spectrum, and Cox. With DOCSIS 3.1 technology, it supports plans up to 6Gbps, making it ideal for heavy internet users, gamers, or families with multiple devices. One of its major advantages is the built-in WiFi 6 capability, which enhances speed and coverage, offering connectivity for up to 30 devices across 2,500 square feet.

In terms of connectivity, this modem comes equipped with four 1 Gig Ethernet ports and one multi-gig port, allowing for fast wired connections for gaming consoles and streaming devices. The two-port aggregation feature is a nice touch for users looking to maximize their internet speeds, especially for streaming and online gaming.

It's important to note that the CAX80 is not compatible with DSL providers and some others like Verizon and AT&T, which could limit its appeal for users outside of cable internet. While it includes built-in security features through NETGEAR Armor, users should be aware that the 30-day trial period for this software will require a subscription afterward for ongoing protection.

Ease of use is another strong point, as the Nighthawk app allows for simple setup and management of your WiFi network, making it user-friendly. On the downside, some users have reported that the initial setup can sometimes be confusing, particularly for those who are not tech-savvy.

This modem-router combo is well-suited for high-speed cable internet users looking for a powerful solution that reduces rental fees by combining devices. However, potential buyers should check compatibility with their internet service provider and consider the ongoing costs associated with security features.
