10 Best Xfinity Modems 2025 in the United States

The Motorola MG7700 Modem WiFi Router Combo is a versatile device designed for households seeking to consolidate their modem and Wi-Fi router into a single unit. It is compatible with major ISPs like Comcast Xfinity, Cox, and Spectrum, making it a convenient choice for many users. The modem supports DOCSIS 3.0 and offers downstream speeds up to 1000 Mbps, although it is optimized for service plans up to 800 Mbps. This should be sufficient for most standard residential internet needs, including streaming and gaming.

The built-in router features AC1900 dual-band Wi-Fi, which can handle both 2.4GHz and 5GHz frequencies, enhancing your wireless coverage and performance. Additionally, four Gigabit Ethernet ports allow for fast wired connections to multiple devices. The Power Boost technology further amplifies the Wi-Fi signal, improving speed and range, an essential feature for larger homes or spaces with multiple users.

One of the primary benefits of the MG7700 is the potential cost savings, as it can eliminate the need for modem rental fees from your ISP, potentially saving you up to $156 per year. However, it's important to note that this modem is not compatible with fiber optic, DSL, or satellite services. Also, while it offers robust performance for DOCSIS 3.0, it may not be future-proofed for users anticipating higher speeds or DOCSIS 3.1 adoption. The Motorola MG7700 is a strong contender for users within its compatibility range, offering solid performance, extensive features, and significant cost savings.

The Hitron CODA56 Multi-Gigabit DOCSIS 3.1 Modem is designed for users with high-speed internet plans, supporting speeds up to 2.5 Gbps. It's compatible with major ISPs like Xfinity, Spectrum, and Cox. The modem shines with its DOCSIS 3.1 standard, which is ten times faster than DOCSIS 3.0, ideal for users who need fast internet for gaming, streaming, and video conferencing. One major advantage is the ability to save on rental fees, potentially saving up to $168 annually.

The 2.5 gigabit Ethernet port ensures your router can handle these high speeds, but it’s crucial to note that this modem lacks built-in WiFi or router capabilities. This means you’ll need a separate router or WiFi mesh system to connect your devices wirelessly. While the modem offers significant speed improvements and excellent compatibility with major ISPs, it's not suitable for DSL, fiber, fixed wireless, or satellite services, and it doesn't work with providers like AT&T, Verizon, and Google Fiber.

With a customer rating of 4.2 out of 5 stars, most users find it reliable and high-performing, though some might find the lack of built-in WiFi limiting. This modem is ideal for tech enthusiasts and heavy internet users who have or plan to upgrade to high-speed internet plans and don’t mind using separate devices for WiFi connectivity.

The Motorola MT7711 is a versatile device that combines a cable modem, AC1900 router, and phone ports compatible with Comcast XFINITY services. As a DOCSIS 3.0 modem with 24x8 channel bonding, it supports internet speeds up to 400 Mbps, making it suitable for most household internet needs. The built-in router with dual-band WiFi and Power Boost technology enhances wireless speed and range, ensuring reliable connectivity for multiple devices.

Additionally, four Gigabit Ethernet ports allow for high-speed wired connections to multiple devices, which can be beneficial for gaming or streaming needs. The modem includes two phone ports for XFINITY Voice services, making it convenient for users who rely on landline services through their internet provider. The device's robust security features, including a Broadcom cable modem chipset, help protect against Denial of Service attacks, enhancing your network's safety.

It is important to note that this modem is only compatible with Comcast XFINITY and will not work with other internet service providers. Also, it lacks a backup battery option, which means phone services would not be available during a power outage unless an additional battery (Model 98250) is purchased. This product is a solid choice for Comcast XFINITY users looking to eliminate rental fees and integrate their modem, router, and phone services into a single device, but it's essential to consider the lack of cross-provider compatibility and the optional nature of the backup battery.
