10 Best Cable Modem 2025 in the United States

The NETGEAR Nighthawk Cable Modem with Built-in WiFi 6 Router (CAX80) is a robust option for those looking to enhance their home internet experience. It supports the latest DOCSIS 3.1 standard, making it a good fit for high-speed cable internet plans, particularly those reaching up to 6Gbps. With dual-band WiFi 6 capability, it offers a strong connection for up to 30 devices and covers areas up to 2,500 sq. ft., which is excellent for larger homes.

One of its standout features is the four 1 Gig Ethernet ports, along with a 2.5 Multi-gig port, allowing users to connect multiple devices and even achieve faster speeds through port aggregation. This feature is particularly beneficial for gamers and streamers who demand high bandwidth. Additionally, the inclusion of NETGEAR Armor software adds a layer of security, protecting your network and devices from potential threats.

The setup process is user-friendly, thanks to the Nighthawk app, making it accessible even for those who aren't very tech-savvy. However, it's important to note that this device is specifically designed for use in the U.S., which means international users will need to look for alternatives. The CAX80 is an excellent choice for anyone on a compatible cable plan looking for high-speed internet and strong WiFi performance, though it comes with certain limitations regarding ISP compatibility.

The NETGEAR Nighthawk Multi-Gig Cable Modem (CM2000) is an excellent choice for those looking to maximize their internet speed, especially if you have a cable plan that supports up to 2.5Gbps. Its biggest strength is its DOCSIS 3.1 technology, which is the latest standard providing faster and more reliable internet connections. The 32X8 channel bonding and OFDM(A) 2x2 further enhance its performance, making it suitable for high-speed internet plans.

Additionally, it comes with one 2.5 Gig Ethernet port, allowing for the fastest wired internet connections, which is a significant advantage if you need stable, high-speed connectivity for activities like gaming or streaming in 4K resolution. It's also a cost-effective option in the long run as it can replace your rented modem, potentially saving you up to $168 a year in rental fees. The compatibility with major cable internet providers like Xfinity, Spectrum, and Cox means it will work seamlessly with most of the popular ISPs.

However, it's important to note that it is not compatible with DSL providers, Verizon, AT&T, CenturyLink, DirecTV, DISH, or any bundled voice services, which limits its use. Also, it does not have a built-in router, so you will need to connect it to a separate WiFi router for wireless connectivity. This modem is designed for use in the US only, which could be a limitation if you need a modem for international use. Despite these minor drawbacks, the CM2000 offers robust performance and compatibility for users seeking top-tier internet speeds.

The Motorola MG8702 is a solid choice if you’re looking to combine a cable modem and a Wi-Fi router in one device. It supports the latest DOCSIS 3.1 standard, which means it's ready for the fastest internet plans today and offers some future-proofing for when internet speeds increase. It’s approved for major ISPs like Comcast Xfinity, Cox, and Spectrum, so compatibility shouldn’t be a problem for most users.

The built-in AC3200 Wi-Fi router supports dual-band frequencies (2.4 GHz and 5 GHz) and uses advanced features like beamforming and Power Boost to help your Wi-Fi reach farther and stay more reliable. This makes it a good fit for homes with multiple devices like gaming consoles, smart TVs, and smartphones. It also includes a useful mobile app for easy setup, guest network management, parental controls, and security alerts, which is great if you want a simple way to manage your network.

Some users note the device is a bit bulky compared to separate units, and since it combines a modem and router, if one part fails, you’ll need to replace the whole unit. However, owning this device can save you money on rental fees from your ISP, which adds up over time. For average home users wanting good Wi-Fi coverage and speed without extra hassle, the MG8702 is a practical and dependable combo device that supports high speeds and major providers.
