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. 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 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.
