10 Best Modems 2025 in the United States

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 ARRIS SB8200 Cable Modem is a powerful device designed for users who need fast internet speeds and reliable connectivity.

The modem is compatible with major U.S. providers like Comcast Xfinity, Cox, and Spectrum, ensuring broad usability.

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.

It features three Ethernet ports, including a 2.5 Gigabit port for direct connection to a high-speed router, providing blazing-fast performance, or allows link aggregation with two Gigabit ports to achieve speeds up to 2Gbps.
