10 Best Fios Compatible Modems 2025 in the United States

The ARRIS SB8200 cable modem is a strong contender for those seeking a high-speed, fios-compatible modem. One of its major strengths is its DOCSIS 3.1 technology, which is 10 times faster than the older DOCSIS 3.0 standard. This enables faster internet speeds, reduces lag for gaming, and supports multi-gig networking. The modem is compatible with major U.S. cable internet providers like Comcast Xfinity, Cox, and Charter Spectrum, and it's approved for internet speed plans up to 1 Gbps. This makes it suitable for households that require fast streaming and downloading capabilities.

Additionally, it includes two 1-Gigabit Ethernet ports, allowing easy connection to a Wi-Fi router or other wired devices. Another benefit is the potential cost savings, as owning this modem can reduce cable modem rental fees by up to $168 per year, depending on the service provider. Setting up the modem is straightforward with the SURFboard Central App, ensuring a simple and secure installation process.

However, there are some limitations to consider. The ARRIS SB8200 does not include built-in Wi-Fi capabilities, meaning users will need a separate Wi-Fi router to connect wireless devices. Additionally, it lacks telephone ports, which might be a drawback for users who require VoIP services. Despite these limitations, the modem offers strong security features and reliable performance, making it a solid choice for users looking to upgrade their home connectivity.

The NETGEAR Nighthawk Cable Modem CM1200 is a strong contender for those seeking a high-speed modem compatible with major cable internet providers like Xfinity, Spectrum, and Cox. One of its major strengths is its wide compatibility with cable providers, making it a versatile choice, though it is not suitable for Verizon Fios, AT&T, CenturyLink, or other DSL providers. The modem supports internet speeds up to 2Gbps, which is excellent for high-bandwidth activities like streaming and gaming. It features DOCSIS 3.1 technology and 32x8 channel bonding, enhancing its ability to handle high-speed data efficiently, reducing lag and improving performance during peak usage times.

Additionally, it offers four Gigabit Ethernet ports, allowing for reliable wired connections to multiple devices. For those who already have a Wi-Fi router, it can be easily connected to the modem, ensuring all wireless devices are covered. However, it does not have built-in Wi-Fi, which means a separate router is necessary. Users can also benefit from saving on rental fees from their internet service provider, as this modem can replace the rented equipment. The modem also includes link aggregation, combining two 1G ports into a single 2G port for even faster wired speeds.

While its primary focus is on cable internet, the modem's lack of compatibility with DSL or bundled voice services is a limitation. The NETGEAR Nighthawk CM1200 is best suited for those with cable internet looking for high-speed performance and multiple wired connections, provided they have a separate Wi-Fi router.

The NETGEAR Nighthawk Cable Modem WiFi 6 Router Combo (model CAX30S) is a versatile device that combines a modem and router, making it ideal for home use. It is compatible with major cable internet providers like Xfinity, Spectrum, and Cox, but not with Verizon Fios, AT&T, CenturyLink, or DSL providers. This modem-router combo supports high-speed internet plans up to 2Gbps, making it suitable for users with demanding internet needs.

The device features DOCSIS 3.1 technology and 32x8 channel bonding, ensuring high-speed and reliable internet connectivity. Its WiFi 6 (AX2700) capability covers up to 2,000 sq. ft. and can handle up to 25 concurrent devices, making it a strong contender for households with multiple users and devices. With four 1 Gig Ethernet ports and a USB 3.0 port, it offers ample connectivity options for wired devices like computers, gaming consoles, and streaming players.

Security is a highlight, with NETGEAR Armor software providing real-time protection against cyber threats, though the subscription is only free for the first 90 days. The router also features automatic firmware updates and other safety measures for added security. Setup and management are user-friendly via the Nighthawk app. However, one downside is its limited compatibility with certain internet service providers, which could be a deal-breaker for some users. Additionally, while the device promises significant savings on rental fees, the initial purchase price might be considered steep. This NETGEAR Nighthawk model is a robust choice for high-speed, secure home internet, provided it matches your internet service provider.
