10 Best Internet Modems 2025 in the United States

The NETGEAR Nighthawk Modem Router Combo (CAX30) is a robust option for users needing a reliable internet modem with built-in WiFi capabilities. It is compatible with major cable internet providers like Xfinity, Spectrum, and Cox but not with providers like Verizon or AT&T. This modem supports DOCSIS 3.1, ensuring fast and efficient internet speeds, ideal for plans up to 2Gbps. The WiFi 6 technology offers speeds up to 2.7Gbps and can cover up to 2,000 sq. ft., making it suitable for medium to large homes.

It can handle up to 25 devices simultaneously, which is great for households with multiple users and devices. It features 4 Ethernet ports for wired connections, a USB 3.0 port for additional storage or peripherals, and dual-band frequency to optimize network performance. One notable advantage is that it replaces both your cable modem and WiFi router, potentially saving you on rental fees. Setup and management are straightforward with the Nighthawk app.

On the security front, NETGEAR Armor offers real-time protection against hackers, though the trial is only 30 days. Automatic firmware updates add an extra layer of safety for your devices. However, it's not suitable for users with DSL services or those needing bundled voice services. If your priority is fast, reliable internet with extensive coverage and multiple device support, the NETGEAR CAX30 is a dependable choice.

The ARRIS SURFboard SB8200 is a high-performance DOCSIS 3.1 cable modem geared towards users who need fast internet speeds and reliable connectivity. It's compatible with major U.S. cable internet providers like Comcast Xfinity, Cox, and Spectrum, ensuring broad usability. The modem supports internet speed plans up to 1-Gbps and features four OFDM channels, which enhances speed and reliability, making it great for activities like streaming HD content and gaming.

One of its strong points is the DOCSIS 3.1 technology, which is 10 times faster than the previous DOCSIS 3.0 standard, providing better security and reduced lag during online activities. Additionally, the modem includes two 1-Gigabit ethernet ports, allowing for flexible connectivity to routers and wired devices, although it doesn't have a built-in router itself. This means you'll need an external Wi-Fi router to set up a wireless network at home.

The setup process is simple and secure, facilitated by the SURFboard Central App. Another benefit is the potential cost savings, as owning this modem can reduce cable modem rental fees. It is essential to verify compatibility with your ISP. The device is compact and lightweight, making it easy to place in any home setting. It also comes with dedicated customer support, which is a bonus for troubleshooting and assistance. Despite its many strengths, some users might find the lack of a built-in router a limitation, as it necessitates purchasing an additional device for Wi-Fi capabilities.

The NETGEAR Nighthawk CM2000 is a solid choice if you’re looking for a cable modem that can handle very fast internet plans, up to 2.5Gbps. It supports the latest DOCSIS 3.1 standard, which means it’s designed to deliver faster and more reliable speeds compared to older models. With 32 downstream and 8 upstream channels, plus advanced OFDMA technology, this modem can handle a busy home or small office with multiple devices streaming or gaming at once.

It has one 2.5 Gigabit Ethernet port to connect directly to a router or a computer, supporting multi-gigabit speeds without bottlenecks. However, the CM2000 does not have a built-in WiFi router, so you’ll need a separate wireless router to get WiFi throughout your home. Compatibility-wise, it works well with major US cable providers like Xfinity, Spectrum, and Cox, but it’s not suitable for DSL or fiber services such as Verizon or AT&T, nor does it support bundled phone services.

If you have one of the compatible cable providers and a fast internet plan, this modem can save you rental fees and future-proof your setup. For those needing WiFi combined or support for other connection types, other devices would be more suitable. Its size and weight are manageable, and many users find it reliable and straightforward to set up.
