10 Best Modems 2025 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 Motorola MG8725 is a solid choice if you're looking for a combined modem and WiFi 6 router that supports very fast internet plans. It uses the latest DOCSIS 3.1 standard, which allows faster speeds and better future-proofing compared to older DOCSIS 3.0 models. The modem offers one 2.5 Gigabit Ethernet port plus three standard Gigabit ports, giving you flexibility in wired connections for devices like gaming consoles or smart TVs. The built-in router supports WiFi 6 (AX6000), which means improved wireless speed and coverage, thanks to features like beamforming and range boosting.

You'll also appreciate the low latency certification, which can reduce lag for gaming or video calls once your provider enables it. Setup is straightforward through the dedicated app, which also offers security and parental controls. This model isn’t compatible with Comcast’s newer 5G internet service, so if you have or plan to get that, this modem won’t work for you. For most cable internet users with plans up to several gigabits per second, this device offers excellent speed, easy control, and the convenience of saving rental fees by owning it outright.
