4 Best Cable Modem With Voice Line 2025 in the United States

The Motorola MT7711 is a versatile device combining a cable modem, gigabit router, and voice line support, specifically designed for Comcast XFINITY users. It supports the DOCSIS 3.0 standard, ensuring good internet speeds and reliability. With 24x8 channel bonding, it can handle high-speed internet up to 400 Mbps, suitable for most household needs. The inclusion of two phone ports makes it a valuable option for users who need voice service compatibility.

Additionally, it offers AC1900 dual-band Wi-Fi, which provides robust wireless connectivity across both 2.4GHz and 5GHz frequencies, ensuring good coverage and speed for multiple connected devices. The product includes four gigabit Ethernet ports for wired connections, enhancing its versatility for different devices. One major advantage is the potential savings on rental fees, as owning this device can eliminate up to $156 per year in costs.

However, it's important to note that this modem/router is exclusively compatible with Comcast XFINITY services, limiting its use for customers of other ISPs. Another downside is the lack of a backup battery, which means phone calls cannot be made during power outages unless separately purchased. At 3.56 pounds with dimensions of 8.25 x 2.25 x 9 inches, it is reasonably compact and easy to set up. The MT7711 is a strong contender for XFINITY users seeking a comprehensive solution for internet and voice services.

The ARRIS T25 Cable Modem is a solid choice for users of Comcast Xfinity Internet and Voice services. One of its biggest strengths is its adoption of DOCSIS 3.1 technology, which is significantly faster and more secure than the previous DOCSIS 3.0 standard. This modem supports high-speed internet plans up to 800 Mbps, making it suitable for demanding activities like gaming and streaming. Additionally, it features two 1 Gbps Ethernet ports, which can be beneficial for wired connections that require stable and fast internet speeds.

By owning the modem, users can save up to $168 annually in rental fees, which is a great cost-saving advantage. The setup process is straightforward, involving plugging in the device and using the SURFboard Central App for activation. However, it's important to note that the ARRIS T25 does not include Wi-Fi capabilities, necessitating a separate Wi-Fi router if wireless connectivity is required. Furthermore, it is only compatible with Xfinity services, limiting its use if you switch internet providers. In terms of physical design, the modem is relatively compact and lightweight, with dimensions of 2.68 inches in length, 7.17 inches in width, and 10.55 inches in height.

The ARRIS T25 is highly praised, with a customer rating of 4.1 out of 5 stars from 1,724 reviews. In summary, this modem is ideal for Xfinity users needing both internet and voice capabilities and looking for a reliable, high-speed, wired connection.

Additionally, the AC2350 Wi-Fi standard ensures reliable wireless connections for various devices, including smart TVs and personal computers.

Setting up the device is straightforward and can be managed using the SURFboard Central App, which also provides features like real-time network monitoring and parental controls. However, this device is limited to DOCSIS 3.0, whereas some newer models support DOCSIS 3.1, which offers better performance and future-proofing. Its compatibility is limited to Xfinity services, so it wouldn't be the right choice if you use a different ISP. For Xfinity users, it is a robust option that combines modem and router functionalities, potentially saving you on rental fees.
