6 Best Modem Router Combo For Xfinity With Telephone Jack 2025 in the United States

The NETGEAR Nighthawk Multi-Gig Cable Modem (CM2050V) is designed specifically for Xfinity users, supporting internet plans up to 2.5Gbps. This modem-router combo stands out with its DOCSIS 3.1 technology, ensuring fast and reliable internet speeds that cater to high-demand users. One of its major strengths is the ability to accommodate up to two telephone lines, complete with advanced calling features like caller ID and call forwarding, making it an excellent choice for homes relying on VoIP services.

In terms of connectivity, it includes a 2.5 Gig Ethernet port, allowing for ultra-fast wired connections. This is particularly beneficial for users with multiple devices that require stable internet access, such as gamers or streamers. The ability to connect any WiFi router further enhances its versatility, giving users the freedom to choose their desired wireless setup.

There are some limitations to consider. The CM2050V is not compatible with Verizon Fios, AT&T, or fiber services, which may restrict its appeal to customers outside the Xfinity ecosystem. Additionally, while the modem is fairly easy to set up, those who are less tech-savvy may find some features and configurations challenging without additional assistance. It's also worth noting that while it can replace your rented equipment and save you on rental fees, this upfront investment might not be justified for users with lower-speed plans. The modem’s dimensions are compact, fitting easily into most home setups, but its performance is best utilized with high-speed service.

The Motorola MT7711 is a three-in-one device that combines a DOCSIS 3.0 cable modem, an AC1900 dual band Wi-Fi router, and two Xfinity-compatible phone ports, making it a convenient choice for Comcast Xfinity subscribers. It supports internet speeds up to 400 Mbps, which is sufficient for most home users. The inclusion of four Gigabit Ethernet ports allows for multiple wired connections, making it suitable for households with several devices requiring stable wired internet.

Additionally, the power boost technology enhances Wi-Fi speed and range, providing better wireless performance. The compatibility with Xfinity Voice adds the benefit of using digital voice services without needing a separate device. Users will appreciate the potential savings on rental fees over time.

However, it's important to note that it only works with Comcast Xfinity services and not with other internet providers. Furthermore, it lacks a backup battery option, which means it won't support phone calls during a power outage. Setting up the device is straightforward, but non-tech savvy users might require some assistance with initial configuration. For Xfinity users looking for an all-in-one solution, the Motorola MT7711 offers a solid mix of performance, convenience, and cost savings, despite the few limitations.

The ARRIS SURFboard SVG2482AC is a solid choice for those seeking a modem-router combo compatible with Xfinity, especially if you also need a telephone jack for voice services. Its DOCSIS 3.0 technology supports internet speeds up to 800 Mbps, making it suitable for streaming and gaming, which can benefit both home users and small business setups. The dual-band AC2350 Wi-Fi provides good coverage, although the actual performance can vary based on your home’s layout and interference.

One of the standout features is the potential cost savings; by owning this modem, you could save around $168 a year in rental fees from your internet provider. The setup process is straightforward, aided by the SURFboard Central App that guides you through activation and network customization. The app also offers features like real-time monitoring and parental controls, which many users find helpful for managing their home networks.

There are a few considerations to keep in mind. While the 4 Ethernet ports are a plus for wired connections, the modem may not perform optimally for multiple high-demand devices simultaneously, especially in larger households. The DOCSIS 3.0 standard, while still effective, is not the latest technology available, meaning that if you plan on upgrading your internet speeds significantly in the future, you might want to consider a DOCSIS 3.1 option instead.
