10 Best Cable Modem 2026 in the United States

The ARRIS SURFboard SB8200 is a solid choice for those looking to upgrade their home internet experience, particularly for users with high-speed connections. With DOCSIS 3.1 technology, it supports internet speeds up to 1 Gbps, making it a great fit for heavy internet users who stream, game, or download large files. Its compatibility with major U.S. cable providers like Xfinity, Cox, and Spectrum ensures that it can meet the needs of many households.

One of the standout features of the SB8200 is its channel bonding capability, which allows for better speed and efficiency. This modem includes two 1-Gigabit ethernet ports, enabling you to connect multiple devices directly for stable wired connections. Additionally, you can save money over time by owning the modem instead of renting one from your ISP, potentially cutting your bills significantly.

While the SB8200 is powerful, it lacks a built-in Wi-Fi router, which means you'll need to purchase a separate router for wireless connectivity. This could be an added expense for some users. The setup process is straightforward with the SURFboard Central App, but those who aren't particularly tech-savvy might still find it a bit challenging if they encounter issues. Moreover, it’s slightly bulkier compared to other modems, which could be a consideration for those with limited space. Customer support is available, which is reassuring for first-time users. The ARRIS SB8200 is a powerful modem for anyone looking to maximize their internet speed, but make sure to pair it with a compatible router for a complete home connectivity solution.

The Motorola MB7621 is a solid choice if you want a reliable cable modem without built-in WiFi. It supports DOCSIS 3.0, which is still common and works well with most cable Internet providers like Comcast Xfinity, Cox, and Spectrum. This modem is great for internet plans up to around 650 Mbps, making it suitable for many home users with moderately fast speeds. With one Gigabit Ethernet port, you’ll connect it to your own WiFi router or directly to a device that needs wired internet. It doesn’t have a built-in router, so if you want wireless WiFi, you’ll need a separate router or mesh system.

The MB7621 is praised for fast, stable connections thanks to its Full-Band Capture Digital Tuner, which helps maintain reliable signals. Setup is straightforward, and the compact design won’t take up much space. One downside is it doesn’t support the newest DOCSIS 3.1 standard, so if you have plans to upgrade to internet speeds over 900 Mbps or want more future-proofing, this model might feel limited. Also, it doesn’t support phone services or have multiple Ethernet ports for connecting several wired devices directly.

However, it’s an affordable way to avoid rental fees from ISPs and works well with popular mesh WiFi systems. Its two-year warranty and protection against power surges add extra peace of mind. If you have a cable internet plan under 650 Mbps and prefer using your own router, this modem offers a dependable, budget-friendly option.

The Motorola MG8725 is a powerful 2-in-1 device that combines a cable modem and a WiFi 6 router. It uses the latest DOCSIS 3.1 standard, which is great for high-speed internet plans and future-proofing your setup. The modem is backward compatible with DOCSIS 3.0, ensuring it works with older networking standards as well. This means you can get ultra-fast internet speeds up to 6000 Mbps, depending on your service plan, making it ideal for heavy internet users, gamers, and households with multiple devices streaming simultaneously.

The built-in AX6000 router supports advanced features like Power Boost, Range Boost, and AnyBeam beamforming to enhance WiFi coverage across your home. The inclusion of one 2.5 Gig ethernet port and three 1 Gig ethernet ports provides flexible, high-speed wired connection options for various devices. Another standout feature is its Low Latency DOCSIS certification, which can significantly reduce lag during gaming, streaming, and video conferencing, although it requires firmware updates from cable providers to be fully utilized.

Setting up the device is user-friendly with the motosync app, allowing you to manage your network effortlessly with features like speed tests, guest networks, and parental controls. Safety features include malware blocking and the ability to create family profiles to control internet access and content. However, it's important to note that this model is not compatible with Xfinity 5G internet, which could be a limitation if you plan to use that service in the future. Additionally, while the initial cost might be high, the device can save you up to $168 a year on modem rental fees. The Motorola MG8725 is a top-tier choice for those looking to combine high-speed internet and comprehensive home network management in one device.
