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 Modem Router Combo (CAX30) is a strong contender in the router-modem-combo category, particularly for households and small businesses needing reliable and fast internet. With DOCSIS 3.1 compatibility, it supports internet plans up to 2Gbps, making it a great choice for heavy users such as gamers and streaming enthusiasts. The Wi-Fi 6 (AX2700) technology allows for fast wireless speeds up to 2.7Gbps, and it covers an area of up to 2,500 square feet, accommodating up to 25 devices simultaneously, which is impressive for larger homes or busy networks.

Strengths include its four Gigabit Ethernet ports, which allow for multiple wired connections and support port aggregation for increased bandwidth. The inclusion of a USB 3.0 port is a nice touch, enabling easy access to shared storage or other devices. Security features are robust, thanks to NETGEAR Armor for real-time protection against online threats, and automatic firmware updates ensure that the system stays secure.

However, it’s worth noting some drawbacks. While it is compatible with major cable providers like Xfinity and Spectrum, it does not support DSL services or bundled voice services, which could limit options for some users. Additionally, while the range is adequate for most residential needs, if you have a particularly large home or numerous obstacles (like walls), there may be areas with weaker signal strength. The price, while justifiable given the features, might be a bit high for those with basic internet needs who do not require such advanced performance. The Nighthawk CAX30 is excellent for cable internet users wanting high speeds and a solid security infrastructure, but it may not be necessary for users with basic internet needs or those using non-cable services.

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.
