10 Best Router Modem Combos 2025 in the United States

The ARRIS G54 combo is a powerful choice if you're looking to combine your modem and router into one device. It supports the latest DOCSIS 3.1 standard, which means it can deliver internet speeds up to 18 Gbps—much faster than most home internet plans today. This makes it great for heavy streaming, gaming, or managing many devices at once. The Wi-Fi 7 technology is cutting-edge and offers excellent speed and reliability, covering up to 5,000 square feet, which should be enough for most average to large homes.

It features four 1-Gigabit Ethernet ports plus a super-fast 10-Gigabit port, so you can connect wired devices like gaming consoles or smart TVs with very stable connections. This product works well with major US internet providers such as Xfinity, Spectrum, and Cox, and owning it can help you save on rental fees. On the downside, the device is somewhat large in size and might be more expensive upfront compared to basic models. Also, Wi-Fi 7 is very new, so not all devices can fully take advantage of it just yet.

The ARRIS G54 represents a strong option for those seeking top-tier speed, broad coverage, and future-proofing in a modem-router combo, especially if your internet plan and devices can match its high performance.

The NETGEAR Nighthawk CAX80 is a solid choice if you’re looking for a modem-router combo that works well with major cable internet providers like Xfinity, Spectrum, and Cox. It supports DOCSIS 3.1, the latest standard for cable modems, allowing internet plans of up to 2 Gigabits per second, making it future-proof for many fast internet packages. Featuring Wi-Fi 6 technology, it provides faster wireless speeds and supports 45 or more devices, which is ideal for busy homes or small offices. Its dual-band Wi-Fi covers about 3,000 square feet, suitable for average-sized houses.

The device includes one 2.5 Gigabit Ethernet port and four standard Gigabit ports, offering multiple options for wired connections to devices like gaming consoles or smart TVs. In terms of security, it supports common WPA/WPA2 protocols to help keep your network safe. However, it is not compatible with DSL or fiber providers such as Verizon or AT&T, so it is limited to cable internet users. While it supports high speeds, the maximum internet plan it is built for is 2 Gbps, despite advertising up to 6 Gbps Wi-Fi speeds, which represent theoretical wireless throughput rather than actual internet speed.

Additionally, it is dual-band rather than tri-band, which might be a consideration if you have a very high number of devices or want extra bandwidth management. For those looking to avoid monthly rental fees and have cable internet from a supported provider, this device provides a powerful, all-in-one solution with modern features and good coverage.

The ARRIS G20 Cable Modem Router Combo is a strong contender in the router-modem-combo category, boasting several impressive features. With DOCSIS 3.1 technology, it promises internet speeds up to 1.0 Gbps, making it suitable for high-speed internet plans offered by major U.S. providers like Comcast Xfinity, Cox, and Spectrum. The inclusion of Wi-Fi 6 (AX3000) ensures faster and more efficient wireless communication, ideal for modern smart homes with multiple devices like gaming consoles, smart TVs, and security cameras.

The dual-band frequency (2.4 GHz and 5 GHz) ensures flexible connectivity options and better performance in crowded network environments. Additionally, the device includes four Ethernet ports, providing wired connections for devices requiring stable and fast internet access. Security features such as guest mode, internet security, and parental controls enhance user safety and control over their network. Another notable advantage is the potential cost savings; owning this modem can save users up to $180 per year compared to renting equipment from their ISP.

However, there are some drawbacks to consider. The ARRIS G20 is relatively bulky with package dimensions of 9.53 x 7.68 x 4.41 inches and a weight of 2.4 pounds, which might be a concern for those with limited space. Additionally, while the device is optimized for next-generation upload speeds, these benefits are dependent on the service tiers provided by the user's ISP. In summary, the ARRIS G20 is well-suited for users seeking a high-performance, future-proof modem-router combo with robust security and control features.
