Design and Build
The Netgear RAX120-100NAS has a distinct, angular design typical of the Nighthawk gaming and performance line. Its black chassis measures 12.2 by 7.48 by 1.77 inches, giving it a substantial footprint that is not designed to be inconspicuous. The unit houses eight high-performance internal antennas, which Netgear states are configured to amplify WiFi signals for maximized range. This design choice contributes to the router’s claimed coverage of 3,500 square feet. The build is functional, with ventilation likely intended to manage heat from the powerful 2.2 GHz quad-core processor inside. While specific materials are not listed by the manufacturer, the router has a weight of 2.1 kilograms, suggesting a solid construction.
Performance and Features
Wireless Performance and Technology
At its core, the RAX120 is a WiFi 6 router, which brings several key advancements over previous generations. The AX6000 rating signifies a theoretical combined wireless speed of up to 6 Gbps across its dual 2.4 GHz and 5 GHz bands. It utilizes 12 streams to distribute data, which, combined with technologies like OFDMA (Orthogonal Frequency-Division Multiple Access) and MU-MIMO, is designed to handle multiple devices efficiently. This is crucial for modern homes where smartphones, laptops, smart TVs, and IoT devices all compete for bandwidth simultaneously. The router also features Beamforming+ technology, which focuses WiFi signals towards connected devices to improve speed and reliability.
Connectivity and Ports
Wired connectivity is a significant highlight. The router includes four standard 1 Gigabit Ethernet ports for connecting devices like gaming consoles, PCs, or network-attached storage. Its standout feature is the single 5G Multi-Gig Ethernet port, which supports 1, 2.5, and 5 Gbps speeds. This port is intended to connect to compatible modems offering multi-gigabit internet service, supporting plans up to 2 Gbps through port aggregation. It’s a forward-looking feature for users with or planning to upgrade to ultra-fast fiber or cable internet. Additionally, the two USB 3.0 ports allow users to share a storage drive across the network, effectively creating a personal cloud storage accessible from connected devices.
Software and Security
Management is handled primarily through the Nighthawk app, which Netgear states allows for easy setup and customization. Features reportedly include remote network access, internet speed testing, device-level WiFi settings, and usage monitoring. For security, the router supports the latest WPA3 wireless security protocol. It also includes a 30-day free trial of NETGEAR Armor, which provides an added layer of security software across all connected devices. Other advanced features noted in the specifications include Dynamic QoS (Quality of Service) for prioritizing traffic, a firewall, VPN support, and Guest WiFi access.
Setup, Support and Ownership
Netgear promotes an easy setup process via the Nighthawk app, connecting the router to an existing cable modem. However, user feedback suggests that a wired setup via a PC may be more reliable for some. The router is compatible with any internet service provider, but unlocking its full multi-gig potential requires a separate modem or gateway that supports those speeds. The product includes a one-year warranty from the manufacturer. For ongoing support, Netgear provides firmware updates, and the security features like NETGEAR Armor are subscription-based after the initial trial. The router’s compatibility with Amazon Alexa allows for some basic voice controls.
What Owners Say
Owner feedback presents a mixed but informative picture. The router holds an average rating, with a distribution showing a significant portion of perfect scores and a notable number of low scores. Positive reviews frequently praise the router for solving coverage issues in large homes, providing fantastic speeds that match high-bandwidth internet plans, and reliably handling many connected devices without lag. Several users highlighted its performance as a major upgrade from ISP-provided equipment.
On the critical side, negative reviews often cite reliability concerns, bugs, or difficulties with the initial setup, particularly when using the mobile app. Some users experienced issues that led them to revert to older, more stable router models. This polarity in reviews indicates that when the RAX120 works correctly in a compatible environment, it excels, but it may present challenges that require technical troubleshooting for some users. The feedback underscores the importance of proper setup and compatible supporting hardware.

Who Should Buy It (and Who Should Skip It)
The Netgear RAX120-100NAS is an ideal choice for users in large homes (up to 3,500 square feet) with a high number of connected devices. It is particularly suited for those with gigabit or multi-gigabit internet plans who need a router capable of handling that bandwidth, especially via its unique 5G port. Gamers, 4K streamers, and smart home enthusiasts with many IoT devices will benefit from its OFDMA and multi-stream design. It’s also a strong candidate for those looking to future-proof their network for the next few years.
This router may not be the best fit for users in small apartments, those with basic internet plans below 300 Mbps, or individuals uncomfortable with potentially troubleshooting network setup. If you prefer a simple, set-it-and-forget-it device from your ISP, the complexity and potential setup hurdles of the RAX120 might be frustrating. Those seeking a smaller, more discreet design should also consider other models.

Final Verdict
The Netgear Nighthawk RAX120-100NAS is a feature-packed, high-performance router that sits in the upper tier of home networking. Its specifications are impressive: a blazing-fast AX6000 WiFi 6 radio, a quad-core processor, and that standout 5G Multi-Gig Ethernet port designed for next-generation internet speeds. When configured correctly with compatible hardware, it has the potential to transform the network experience in a busy, connected household, eliminating bottlenecks and providing wide, reliable coverage.
However, its value is contingent on your specific needs and technical comfort. The polarized user reviews serve as a caution that its advanced capabilities come with a steeper setup and reliability curve than some simpler routers. It’s not a universal solution. For the right user—someone with a fast internet plan, a large space to cover, and the willingness to ensure optimal setup—the RAX120 is a powerful tool. For others, a less complex or more consistently reviewed model might be a safer bet. You can find alternatives in our broader router wifi category.
FAQs
What makes the 5G Multi-Gig port on the RAX120 special?
This port supports network speeds of 1, 2.5, and 5 Gigabits per second, unlike standard Ethernet ports capped at 1 Gbps. It is designed to connect to compatible modems from internet service providers that offer multi-gigabit plans (e.g., 2 Gbps fiber). This allows the router to fully utilize these ultra-fast internet connections without being a bottleneck, making it a future-proof feature for upcoming service tiers.
How many devices can the Netgear RAX120 handle effectively?
The manufacturer states the router is designed to support up to 30 devices. This capacity is facilitated by WiFi 6 technologies like OFDMA and MU-MIMO, which allow the router to communicate with multiple devices simultaneously rather than sequentially. This makes it suitable for smart homes with numerous phones, laptops, streaming devices, and IoT gadgets all online at once.
Do I need a new modem to use this router?
You need a separate modem or gateway, as this is a router only. It is compatible with any internet service provider. However, to use its 5G Multi-Gig port and achieve internet speeds above 1 Gbps, you must have a modem that also supports multi-gigabit output via a compatible port. For standard internet plans, a typical cable or DSL modem will work via the standard WAN port.
What is NETGEAR Armor, and is it necessary?
NETGEAR Armor is a subscription-based security service that provides antivirus, anti-malware, and intrusion detection for all devices on your home network. The router includes a 30-day free trial. After that, it requires a paid subscription. While not necessary for basic operation, it offers an added layer of protection beyond the built-in WPA3 encryption and firewall, which some users may value for comprehensive home cybersecurity.
