7 Best Cable Modem Router Combo With Phone Jack 2026 in the United States

The Motorola MT8733 is a solid choice for those in need of a cable-modem-router combo that includes VoIP functionality, particularly for users with Comcast Xfinity service. Its compatibility with Xfinity’s internet and voice services ensures efficient operation, making it an ideal pick for Xfinity customers looking to maximize their internet and phone capabilities. With DOCSIS 3.1 technology, it supports speeds up to 2.5 Gbps, which is excellent for heavy internet users, gamers, and households with multiple devices connected simultaneously.

One of the standout features is its 2.5 Gigabit Ethernet port, which allows for ultra-fast wired connections alongside three additional 1 Gig Ethernet ports. The WiFi 6 capability delivers remarkable wireless performance, ensuring fast and reliable connections throughout your home. The inclusion of two phone ports makes it particularly beneficial for those who want to take advantage of Xfinity's voice services, offering features like caller ID and call forwarding. Additionally, the Smart Motosync app simplifies setup and ongoing management, making it accessible even to less tech-savvy users.

There are some limitations to consider. The MT8733 is exclusively compatible with Xfinity services, meaning those with different internet or phone providers will not be able to utilize this device. While it boasts impressive speeds, achieving close to the maximum speeds may depend on various factors such as the quality of your internet connection and how far you are from the router. The performance is strong, but users should be mindful of the price point. Although it can save you the cost of renting a modem, there is an upfront investment. In conclusion, the Motorola MT8733 is a robust option for Xfinity users seeking a cable modem and router combo with phone capabilities, though its compatibility is limited to one ISP and it may come with a higher initial cost.

The NETGEAR Nighthawk C7100V is a solid choice if you want a cable modem-router combo that supports phone lines, especially for Xfinity internet and voice plans up to 600 Mbps. It combines a DOCSIS 3.0 modem, an AC1900 dual-band Wi-Fi router, and two phone jacks for voice calls, which makes it convenient if you want to cut down on devices. The Wi-Fi supports 802.11ac (Wi-Fi 5), offering good speeds for streaming 4K videos or gaming, and the internal antennas with beamforming help provide wide coverage around your home. There are four gigabit Ethernet ports for wired connections, which is great if you have devices like gaming consoles or desktop computers that need stable, fast internet.

On the phone side, it supports two VoIP lines, which is handy for landline replacement through your internet connection. However, it lacks built-in security update features, so it might require occasional manual checks to keep your network safe. The router has basic firewall protections and common security protocols like WPA2, but it doesn't offer the latest advanced security options. Setup is straightforward with an app for management, but some users might find initial installation a bit technical if they are new to networking gear. Another useful feature is the optional battery backup, which can keep your internet and phone working during power outages for several hours.

The device is not the newest model and runs on DOCSIS 3.0 instead of the faster DOCSIS 3.1 standard, so if your provider supports higher speeds or future upgrades, this device might feel limiting down the line. The NETGEAR C7100V fits well for households looking to combine internet, Wi-Fi, and phone service with decent speed and coverage, especially on Xfinity service, but it may fall short if you want the latest security features or top-tier future-proof speeds.

The ARRIS Surfboard SVG2482AC combines three devices in one: a cable modem, dual-band Wi-Fi router, and telephone adapter designed specifically for Comcast Xfinity internet and phone services. Its 24 download and 8 upload DOCSIS 3.0 channels support internet speeds up to around 600 Mbps, which suits most mid-tier plans but won’t deliver gigabit speeds. The AC1750 Wi-Fi offers dual-band 802.11ac wireless connectivity with a max theoretical speed of 1750 Mbps, enough for everyday browsing, HD streaming, and gaming within a typical home range. Four gigabit Ethernet ports provide reliable wired connections for devices needing stable speed. It includes two phone jacks compatible with Xfinity voice, making it convenient for those using home phone services. Security-wise, it supports WPA2, which is standard for protecting wireless networks.

Setup is straightforward but requires Comcast Xfinity service, as this unit isn’t compatible with other cable providers. One downside is that it doesn't support Xfinity's home security or smart home features unless paired with an additional Comcast router. Also, its internal antennas and range may be average, suitable for small to medium homes but possibly weaker in larger spaces. The product is renewed and backed by a limited warranty, reflecting a budget-friendly choice.

This device serves as a practical option for Comcast customers who want to simplify their setup by combining modem, router, and phone adapter in one unit. However, it is not suitable for users seeking gigabit speeds, broader provider compatibility, or smart home integration.
