5 Best Cable Modem Router Combo With Phone Jack 2025 in the United States

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.

The Motorola MT7711 is a versatile cable modem/router combo that particularly shines for users of Comcast Xfinity services. Its DOCSIS 3.0 standard supports internet speeds of up to 400 Mbps, making it a solid choice for moderate to high-speed internet users. The built-in AC1900 dual-band WiFi offers good wireless coverage and speed, while the four Ethernet ports provide ample options for wired connections, which is great for households with multiple devices. Additionally, having two phone ports for VoIP adds significant value for those who still use a landline for calls.

One of the main advantages of the MT7711 is the potential to save money by eliminating rental fees for a modem, which can be as much as $156 annually. The device also has robust security features to protect against common online threats, which is a nice touch for safeguarding your home network.

The MT7711 comes with some limitations. It is specifically designed for use with Comcast Xfinity, meaning it won’t work with other Internet Service Providers (ISPs). This makes it less versatile for users who might switch ISPs in the future. While the speed and range of the WiFi are generally good, it lacks a battery backup option, which could be a disadvantage in case of power outages for those relying on VoIP services.
