10 Best Modem For Xfinity Gigabit 2025 in the United States

The NETGEAR Nighthawk Modem Router Combo (CAX30) is a strong contender for those needing a modem for Xfinity Gigabit internet plans. It utilizes the latest DOCSIS 3.1 standard, ensuring top performance with a speed rating of up to 2.7 Gbps, making it suitable for high-speed internet plans up to 2Gbps. The device features 32x8 channel bonding, which helps maximize your internet speeds and overall performance.

Its dual-band WiFi 6 technology offers robust coverage up to 2,000 sq. ft. and supports up to 25 concurrent devices, making it ideal for busy households or small offices. For wired connections, the modem includes 4 Gigabit Ethernet ports and 1 USB 3.0 port, which are useful for connecting various devices like gaming consoles, computers, and streaming players. It also provides a significant advantage by eliminating rental fees from your ISP, potentially saving you up to $168 annually.

One of the standout features is the built-in NETGEAR Armor security software, which offers real-time protection against cyber threats, though it comes with just a 30-day trial period. On the downside, the modem is not compatible with DSL, satellite, or fiber services like Verizon, AT&T, and CenturyLink, which limits its usability to cable internet subscribers. Additionally, while its feature set is impressive, the price might be a consideration for budget-conscious users. Nevertheless, the easy setup and management through the Nighthawk app add to its convenience. The CAX30 is geared towards users with high-speed cable internet plans looking for a reliable, feature-rich modem router combo with excellent security and connectivity options.

The ARRIS SURFboard SB8200 is a DOCSIS 3.1 cable modem that stands out with its advanced technology and support for gigabit internet speeds, making it a good choice for Xfinity users. Its DOCSIS 3.1 compatibility ensures faster speeds and better security compared to older standards. The modem supports speeds up to 1 Gbps and has 32 downstream and 8 upstream channels, which is excellent for high-speed internet and reduces lag during activities like gaming or streaming 4K content.

Another notable feature is its two 1-gigabit Ethernet ports, allowing you to connect multiple devices directly for a fast and reliable wired connection. However, this modem does not have a built-in router, so you will need a separate router for Wi-Fi connectivity. The setup is straightforward with the SURFboard Central App, and it is compatible with a wide range of U.S. cable internet providers, including Comcast Xfinity, Cox, and Spectrum. One of the benefits of owning this modem is the potential cost savings on rental fees from your ISP.

The modem’s compact size and solid build, along with the dedicated customer support, offer added conveniences. The ARRIS SURFboard SB8200 is a robust choice for users seeking high performance and future-proofing for their gigabit internet plans, provided they don’t mind adding a separate router for Wi-Fi.

The Motorola MG8725 is a strong choice if you want a single device that works as both a cable modem and a WiFi 6 router, especially for Xfinity Gigabit plans. It supports the latest DOCSIS 3.1 standard, ensuring compatibility with very fast internet speeds up to 6000 Mbps and is backward compatible with older DOCSIS 3.0 plans. It features one 2.5 Gigabit Ethernet port plus three standard 1 Gigabit ports, allowing multiple wired connections which is handy for things like gaming or streaming devices.

The built-in AX6000 WiFi 6 router supports dual-band wireless with beamforming technology, which helps extend your WiFi coverage and improve connection stability around your home. An important benefit is its Low Latency DOCSIS certification, which means less lag during online gaming or video calls. The device also offers useful safety and control features through the Motosync app, making setup and network management straightforward even for non-tech users.

While it delivers fast multi-gigabit speeds and good wireless coverage, some users might find the range could vary depending on home layout and interference. The price may be higher than basic modems, but it could save money over time by eliminating rental fees. This unit is well suited for home users looking for a reliable, high-speed modem-router combo that supports gaming and streaming with future-proof technology.
