10 Best Cable Modem 2026 in the United States

The ARRIS SURFboard SBG7400AC2 is a solid choice if you want a combined cable modem and Wi-Fi router, especially for home use with cable internet providers like Cox, Spectrum, and Xfinity. It uses DOCSIS 3.0 technology, which is reliable and common, but not the latest standard. This means it supports internet speeds up to about 800 Mbps, suitable for most everyday activities like streaming, gaming, and browsing, but may fall short for very high-speed plans or future upgrades.

It has four Gigabit Ethernet ports, allowing multiple wired devices to connect for stable, fast connections. The built-in Wi-Fi supports dual-band AC2350 speeds, providing decent wireless coverage and speed for a typical household. Setup is made easy through an app that helps activate the modem and control your network, including parental controls.

This modem-router combo does not support voice services (no phone line capability) and is not compatible with fiber or DSL providers like AT&T or Verizon. If your internet plan relies on these technologies, this product won’t work. While DOCSIS 3.0 offers solid performance, newer modems with DOCSIS 3.1 provide better future-proofing and faster speed potential. For internet speeds under 800 Mbps, this ARRIS model offers good value and reliable performance for cable internet users who need both modem and router functions in one device.

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 B12 is a solid choice if you need a fast and reliable cable modem, especially for plans with very high internet speeds. It supports the latest DOCSIS 3.1 standard, which means it can handle multi-gigabit internet connections up to about 2,500 Mbps on its 2.5 Gbps Ethernet port. This makes it a good option if you want to make full use of top-tier internet packages from popular providers like Comcast Xfinity, Cox, Spectrum, and others. It supports 32 downstream and 8 upstream channels, which helps maintain stable and fast connections even during busy hours. One thing to note is that this modem does not include a built-in Wi-Fi router, so you’ll need to connect it to a separate router to get wireless internet. If you already have a good router or prefer to choose one yourself, this isn’t a problem.

Owning your own modem like the B12 can save money over time since you avoid monthly rental fees from your ISP. Also, it features technology to reduce internet lag, which can improve online gaming, video calls, and streaming. The compact size makes it easy to fit in most setups, and Motorola provides a 2-year warranty plus US-based support if you run into issues. Since it’s designed mainly for residential use, it might not be suitable for business environments needing advanced features. The Motorola B12 is an excellent modem for anyone wanting fast speeds and solid ISP compatibility without the extra cost of renting equipment, as long as you’re ready to use your own router for Wi-Fi.
