10 Best Frontier Compatible Modem 2026 in the United States

The ARRIS SURFboard SB8200 is a highly capable cable modem, particularly well-suited for users seeking high-speed internet and enhanced connectivity. It supports the latest DOCSIS 3.1 standard, which is 10 times faster than the previous DOCSIS 3.0, ensuring you can make the most out of gigabit-speed internet plans. The modem is compatible with major U.S. cable internet providers like Comcast Xfinity, Cox, and Charter Spectrum, ensuring wide usability.

It supports up to 1 Gbps internet speeds, which is ideal for activities like HD streaming and online gaming, and comes with four OFDM channels for better performance under load. With two 1-Gigabit ethernet ports, you can connect multiple devices directly for maximum speed, though a separate Wi-Fi router is necessary for wireless connectivity. The modem's simple setup, facilitated by the SURFboard Central App, is user-friendly, even for those not particularly tech-savvy.

A key highlight is the potential cost savings, as owning the modem can reduce your cable bill by eliminating rental fees. On the downside, the lack of built-in Wi-Fi capability means an additional purchase of a Wi-Fi router is required to cover wireless devices. Additionally, there are no telephone ports, which might be a drawback for some users needing this feature. The ARRIS SB8200 is a strong choice for those looking for a reliable and fast modem compatible with major ISPs, but it may require additional purchases for a complete home network setup.

The NETGEAR Nighthawk Modem Router Combo (CAX30) is a high-performance device that combines a DOCSIS 3.1 cable modem with a Wi-Fi 6 router.

The CAX30 is designed for cable plans up to 2Gbps, providing robust speed and performance suitable for home, gaming, and business needs.

It offers impressive coverage of up to 2,500 sq. ft. and supports up to 25 concurrent devices, making it ideal for households with multiple users and devices.

Security is a strong point with built-in NETGEAR Armor software that provides real-time protection against cyber threats and a 30-day trial of advanced features. Automatic firmware updates and industry-leading safety features further enhance security. The setup and management of the router are user-friendly, thanks to the Nighthawk app. However, one downside is that it doesn't support any bundled voice services, which might be a consideration for some users. Additionally, while it can save on rental fees, the initial cost might be higher compared to some other modems and routers.
