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 Modem Router Combo (CAX30) is a versatile device that combines a high-speed DOCSIS 3.1 cable modem with a WiFi 6 router, providing speeds up to 2.7 Gbps. It is compatible with major cable providers like Xfinity, Spectrum, and Cox but not with DSL, fiber providers, or services like Verizon and AT&T. This makes it suitable for users with cable internet plans up to 2Gbps. The device covers up to 2,000 sq. ft. and supports up to 25 devices simultaneously, making it a strong choice for medium to large homes.

The 4 Ethernet ports (with port aggregation) and 1 USB 3.0 port provide ample connectivity options for wired devices like gaming consoles and computers. Its dual-band WiFi 6 technology offers improved speed and efficiency, especially in environments with multiple connected devices. The inclusion of NETGEAR Armor adds a layer of security against cyber threats, although this comes as a 30-day trial. Setup and management are simplified with the Nighthawk app.

The product can save you money by eliminating rental fees for separate modems and routers, but it may not be ideal for those who need support for DSL or fiber services. Given its robust feature set and ease of use, it's an excellent option for home users and small businesses looking for a reliable and secure modem-router combo.

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.
