7 Best Modem Router Combo For Xfinity With Telephone Jack 2026 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 MT8733 is designed specifically for Xfinity users, providing a solid option for those looking for a modem-router combo with telephone capabilities. One of its key strengths is its compatibility with Xfinity Internet and Voice service, ensuring seamless integration with their Triple Play plans. This device supports DOCSIS 3.1 technology, allowing for impressive multi-gigabit speeds up to 2.5 Gbps, which is perfect for households with heavy internet usage, such as gaming and streaming. The WiFi 6 (AX6000) performance is another highlight, offering fast and reliable connections across multiple devices.

The inclusion of two phone ports enhances functionality for users who require voice services, featuring additional call management options that can be particularly beneficial for home offices or busy households.

A notable advantage is the potential cost savings; by eliminating rental fees for a modem, users can save up to $168 annually. Plus, the Smart Motosync App simplifies setup and management, making it user-friendly even for those who may not be tech-savvy. However, the Motorola MT8733 is specifically designed for Xfinity, meaning it won't work with other voice services, which could limit its appeal to users who might switch ISPs in the future. Additionally, while the device boasts advanced features, some users might find the initial setup and understanding of all features slightly overwhelming, despite the app's assistance. Lastly, while the performance is excellent, the price point may be higher than that of basic modem-router combos, making it a more significant investment.

The ARRIS T25 is a solid choice for Xfinity users looking for a modem-router combo that supports internet and telephone services. It uses the latest DOCSIS 3.1 technology, which means it can handle faster speeds—up to 800 Mbps with compatible Xfinity plans—making it suitable for streaming, gaming, and everyday internet use. It has two Gigabit Ethernet ports, allowing wired connections for devices like computers or smart TVs, but it doesn’t have built-in Wi-Fi, so you'll need a separate router for wireless coverage.

While it supports voice services through telephone jacks, only two phone ports are available, which may be enough for most home setups but could be limiting if you need more lines. The setup process is straightforward: just plug it in and use the SURFboard Central app to activate, which is friendly for users who are not tech experts. On the security side, the modem follows updated DOCSIS 3.1 standards, offering better protection against online threats, but it doesn’t come preset with Wi-Fi security since it lacks integrated wireless.

It’s compact and reliable, but since it doesn’t include Wi-Fi, you may want to combine it with a good router to cover your home’s wireless range. This modem is great for those wanting to save money by avoiding rental fees and who have Xfinity internet and voice plans up to 800 Mbps. If you expect faster speeds or integrated Wi-Fi, you might look elsewhere, but for its price and features, the ARRIS T25 meets the basic needs of Xfinity users with telephone service quite well.
