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 C7000 is a modem-router combo that stands out for its compatibility with major cable providers like Xfinity, Spectrum, and Cox, making it a versatile choice for users with cable internet plans. However, it does not support Verizon, AT&T, CenturyLink, or DSL providers, which could limit its appeal depending on your internet service provider.

For speed, it supports plans up to 800Mbps and AC1900 WiFi speed, which is suitable for most households and medium-sized homes with coverage up to 1,800 sq. ft. and support for up to 30 devices simultaneously. The DOCSIS 3.0 standard ensures reliable performance, though it's worth noting that it's not the latest DOCSIS 3.1, which might be a consideration for future-proofing your internet setup.

The device includes 4 Gigabit Ethernet ports and a USB 2.0 port, offering good connectivity for wired devices like computers, game consoles, and streaming players. Its security features include WPA/WPA2 protocols and NETGEAR Armor software, providing an added layer of protection with a 30-day trial. The Nighthawk app simplifies setup and management, which can be a big plus for users who aren't particularly tech-savvy. Some might find its size and weight a bit cumbersome, and its made-for-US restriction could be a drawback for international users.
