4 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 ARRIS T25 Cable Modem is a solid choice for those looking for high-speed internet and voice services, particularly if you are a Comcast Xfinity customer. It supports the latest DOCSIS 3.1 technology, which is ten times faster than the older DOCSIS 3.0, making it suitable for high-speed internet needs up to 800 Mbps according to Xfinity's plans. This modem is designed to help you save on rental fees, potentially reducing your cable bill by up to $168 per year.

The device includes two 1 Gbps Ethernet ports, which is useful for connecting multiple wired devices, but it does require an additional Wi-Fi router for wireless networking as it does not have built-in Wi-Fi capabilities. The setup is user-friendly with the SURFboard Central App guiding you through activation, making it accessible even for those who are not tech-savvy. However, it lacks preset Wi-Fi security features, meaning you’ll need to ensure your network is secure through your own router settings.

The modem includes two telephony ports, which is great for users who also need voice service. The product is exclusively compatible with Xfinity, limiting its use with other ISPs. The compact design and lightweight build make it easy to place anywhere in the home. For Xfinity subscribers looking for a reliable modem with voice support, the ARRIS T25 is a commendable option, offering substantial speed and ease of installation.

The ARRIS SURFboard SVG2482AC is a solid choice for anyone looking to combine their cable modem and Wi-Fi router into one device, especially if you're an Xfinity Internet and Voice customer. With DOCSIS 3.0 technology, it supports internet speeds up to 800 Mbps, making it suitable for activities like streaming and gaming. Its dual-band AC2350 Wi-Fi provides excellent coverage and speeds, which is beneficial for multiple devices connected to your home network.

One of the standout features is its two telephony ports for digital voice support, which many users will appreciate for VoIP services. Additionally, the ease of setup through the SURFboard Central App is a significant advantage, allowing for quick activation and customization. The app also offers parental controls, enabling users to manage their children's internet usage effectively.

There are some considerations to keep in mind. First, it’s important to note that the modem is primarily compatible with Xfinity services, so if you use another ISP, this may not be the right fit. While DOCSIS 3.0 is sufficient for many users, it’s worth mentioning that DOCSIS 3.1 is available and offers improved performance for future-proofing against faster internet plans. Also, although it has four Ethernet ports, the speed performance may be lower when multiple devices are connected simultaneously.
