10 Best Cable Modem Wifi Router Combos 2025 in the United States

The NETGEAR Nighthawk CAX80 is a strong choice if you want to combine your cable modem and WiFi router into one device, especially if your internet plan is with major cable providers like Xfinity, Spectrum, or Cox. It uses the latest DOCSIS 3.1 standard, which means it can handle internet speeds up to 2 Gigabits, making it well-suited for fast, modern internet plans. The built-in WiFi 6 technology (also called AX6000) offers fast wireless speeds up to 6Gbps and good coverage around 3,000 square feet, easily supporting 45 or more devices at once. This should be enough for most homes, even those with many connected gadgets. The device provides versatile wired connections including one 2.5 Gigabit Ethernet port and four standard Gigabit Ethernet ports, useful for gaming consoles, computers, or smart home hubs requiring stable and quick connections.

For security, it supports common WPA/WPA2 wireless protocols, protecting your network from basic threats. However, it is not compatible with fiber or DSL internet services from providers like Verizon or AT&T, so it’s only for cable internet users. Also, while it covers a good area, very large homes or thick walls might reduce WiFi performance. The unit replaces rental equipment, which can save you money over time. If you have a cable internet plan and want a future-ready, fast, and multi-device-friendly device with solid wired options, the NETGEAR Nighthawk CAX80 is a reliable and cost-effective choice.

The ARRIS SURFboard G18 is a solid choice if you're looking for a cable modem and Wi-Fi router combo that supports the latest technology, DOCSIS 3.1 and Wi-Fi 6 (AX1800). This means it can handle ultra-fast internet speeds—up to multi-gigabit levels—making it well-suited for streaming, gaming, and multiple devices without lag. It supports most major U.S. cable providers like Comcast Xfinity, Cox, and Spectrum, so compatibility won’t be an issue for many users. The dual-band Wi-Fi 6 offers better speed and range than older models, helping keep your wireless devices connected smoothly throughout a typical home. The setup process is designed to be easy, using a smartphone app that guides you step-by-step and gives you useful features like parental controls and the ability to pause internet access. This can be especially helpful if you have kids or want to manage devices on your network.

While Wi-Fi 6 improves range and speed, very large homes or those with thick walls may still experience some signal drops, which is common in this product category. Security features like guest mode and internet security are included. The ARRIS G18 offers a strong balance of speed, compatibility, and ease of use, making it a good fit for most home users wanting to upgrade to faster, more reliable internet without renting equipment.

The Motorola MG8702 is a solid choice if you're looking for a cable modem and Wi-Fi router combo that supports the latest DOCSIS 3.1 standard, which means it can handle the fastest cable internet plans available now and into the future. Its built-in Wi-Fi router offers AC3200 speed with dual-band coverage, including features like beamforming and Power Boost to improve range and signal strength. It supports compatibility with popular ISPs such as Comcast Xfinity, Cox, and Charter Spectrum, so setup with these providers should be straightforward. The device includes several Ethernet ports for wired connections, ideal for gaming consoles or PCs that require stable connections.

Security features include parental controls, network alerts, and guest network management through an easy-to-use mobile app, adding convenience for controlling access and monitoring your network. One of the significant advantages is the ability to save rental fees by owning your modem, which can save money over time. While the Wi-Fi range covers the essentials well, some users might find it less ideal for very large homes or spaces with many obstacles. Although it supports both 2.4 GHz and 5 GHz bands, the specifications emphasize the 2.4 GHz frequency, so extremely high-speed 5 GHz connections may be limited compared to newer Wi-Fi 6 routers.

This device offers dependable and user-friendly performance suited for most cable internet users who want solid connectivity and easy setup without requiring advanced networking features.
