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 MG7700 is a solid cable modem and Wi-Fi router combination designed for users with cable internet plans up to around 800 Mbps. It uses DOCSIS 3.0 technology with 24 downstream and 8 upstream channels, enabling good download speeds and decent upload speeds suitable for most home internet needs. This device works with major cable providers like Comcast Xfinity, Cox, and Spectrum, though it is important to check with your ISP before buying to ensure compatibility, especially since it doesn’t support fiber, DSL, or satellite connections.

One of the standout features is the built-in AC1900 dual-band Wi-Fi router, which operates on both 2.4 GHz and 5 GHz bands. This helps deliver faster wireless speeds and better coverage, with Power Boost amplifiers that strengthen the Wi-Fi signals to reach farther and perform better with multiple devices like smartphones or laptops. For wired connections, it comes with four Gigabit Ethernet ports, providing reliable, fast connections for devices like gaming consoles or desktop PCs. A practical benefit is the potential cost savings by avoiding monthly modem rental fees from your ISP. However, while the modem supports modem speeds up to 1000 Mbps, the service speed it supports is around 650 Mbps, which might limit performance if your internet plan is faster.

The MG7700 does not support home phone services, so it is not suitable for users relying on voice over cable. Also, as a DOCSIS 3.0 device, it is not the latest standard (DOCSIS 3.1 is newer and faster), so it might not be the best choice for those planning to upgrade to gigabit-plus speeds in the future. The device is easy to set up and comes with reliable customer support. This makes the Motorola MG7700 a great fit for typical cable internet users looking for a cost-effective, combined modem and router solution with solid Wi-Fi performance and multiple Ethernet ports. It covers all basics well but is not geared for top-tier gigabit speeds or more advanced home networking needs.

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.
