NETGEAR Nighthawk RS90 Review: BE3600 Dual-Band WiFi 7 Router

Introduction

The NETGEAR Nighthawk Dual-Band WiFi 7 Router (RS90) is one of those products that looks straightforward until you start comparing the details that actually affect daily use. This review focuses on what stands out in real-world terms, and you can cross-check the spec sheet, manuals, and current firmware on NETGEAR's official RS90 support page.

What These Products Are and Who They're For

The NETGEAR Nighthawk RS90 is a dual-band WiFi 7 router for small-to-midsize homes that want a simple upgrade from an older WiFi 5 or WiFi 6 router. It is a standalone router, not a modem, so it needs to connect to an existing cable modem, fiber ONT, DSL modem, or ISP gateway using Ethernet.

This is not a high-end WiFi 7 router. Its main appeal is bringing newer WiFi 7 features, WPA3 security, app-based setup, automatic firmware updates, and a 2.5Gbps internet port into a more straightforward home-router design. Its main limitations are just as important: it has no 6GHz band, and all four LAN ports are 1Gbps.

For most buyers, the RS90 makes the most sense as a clean, security-focused replacement for an aging router in an apartment, townhouse, or moderate-size home. Power users, heavy wired-network households, and anyone buying WiFi 7 specifically for 6GHz should look higher up the range.

Design and Setup

The RS90 is a compact Nighthawk router with internal antennas, which makes it easier to place than larger gaming-style routers with multiple external antennas. At roughly 7.2 x 2.6 x 4.8 inches, it should fit comfortably on a shelf, media unit, or desk without dominating the space.

Setup is handled through the NETGEAR Nighthawk app or the router’s web interface. The router connects to your modem, fiber ONT, or ISP gateway using its 2.5Gbps WAN port. If your ISP supplied a gateway that already performs routing and WiFi duties, you may need to put that gateway into bridge mode or otherwise configure the network to avoid double NAT.

The key thing to understand before buying is that the RS90 is “router only.” There is no coax input and no built-in modem. Cable internet customers still need a separate cable modem, and fiber or DSL customers need the appropriate ISP-provided termination device or gateway with an Ethernet handoff.

WiFi 7 Features and Real-World Positioning

The RS90 supports WiFi 7, including 4096-QAM and 160MHz channels on the 5GHz band. It also supports MU-MIMO and uplink/downlink OFDMA, features designed to help the router communicate more efficiently with multiple devices.

However, this is an entry-to-midrange WiFi 7 implementation rather than a flagship one. The biggest omission is the lack of a 6GHz band. Many of the most noticeable benefits associated with premium WiFi 7 routers come from adding 6GHz spectrum, especially in congested homes where 5GHz is crowded. The RS90 does not provide that extra band.

Its BE3600 rating is split across two bands: up to about 0.7Gbps on 2.4GHz and up to about 2.9Gbps on 5GHz. Those are link-rate figures, not guaranteed real-world throughput. Actual speeds depend on client devices, distance, wall materials, interference, ISP speed, and network load.

For a small-to-midsize home, the RS90’s rated coverage of up to 2,000 sq. ft. and up to 50 devices is sensible for everyday use: phones, laptops, tablets, streaming boxes, smart TVs, smart speakers, cameras, and other connected devices. Larger homes, difficult floor plans, or homes with thick masonry walls may need a mesh system or a stronger router.

Wired Networking

The port layout is one of the RS90’s clearest strengths and limitations.

The good news is the 2.5Gbps WAN port. That means the router is not capped at 1Gbps on the internet side, which is useful if you have, or plan to get, an internet plan above gigabit speeds.

The limitation is that the four LAN ports are all Gigabit Ethernet. There are no 2.5Gbps LAN ports. That means a single wired desktop, NAS, game console, or switch connected to one of the LAN ports is limited to 1Gbps at that port.

This matters most if you have a fast wired home network, a multi-gig internet plan, or a NAS workflow where local transfer speeds are important. The RS90 can still make sense for homes where most performance demand is on WiFi, but it is not the right foundation for a multi-gig wired network.

Performance Expectations

The RS90 should be viewed as a practical WiFi 7 upgrade, not a maximum-performance router. Its quad-core 2.0GHz processor, 1GB of RAM, and 512MB of NAND flash are credible for a modern mainstream router, and the 2x2 radio design is appropriate for many common client devices.

The best-case fit is a home where most devices are on WiFi, the internet plan is around gigabit or moderately above it, and the router is placed centrally. In that environment, the 5GHz 160MHz channel support and WiFi 7 features can help newer client devices perform well.

The limitations become more obvious in demanding scenarios:

• No 6GHz band for WiFi 6E or tri-band WiFi 7 clients
• No multi-gig LAN for high-speed wired devices
• 2x2 wireless design rather than a higher-spatial-stream premium design
• Coverage rating better suited to small and medium homes than large properties

If you are upgrading from an old ISP router or WiFi 5 system, the RS90 is likely to feel more modern and capable. If you already have a strong WiFi 6E or high-end WiFi 6 router, the upgrade case is narrower.

Security: Attack Surface

Because the RS90 is a network router with app management, firmware updates, VPN support, and optional security services, security matters more here than it would for a simple unmanaged device.

Main security-relevant features

• WPA3 support for stronger WiFi encryption on compatible devices
• Guest WiFi to separate visitors and less-trusted devices from the main network
• Automatic firmware updates to reduce the chance of running outdated router software
• VPN support for remote or private network use cases
• NETGEAR Armor powered by Bitdefender, available as a subscription after any trial period
• Management through the Nighthawk app or web interface

Practical security considerations

The RS90’s automatic firmware updates are a meaningful advantage for typical households, because many router compromises target old firmware. App-based management is convenient, but it also means your NETGEAR account security matters. Use a strong, unique password and enable any available account protections.

The local web interface is useful for more detailed configuration, but router admin access should be treated carefully. Change default credentials during setup, keep the admin password unique, and avoid exposing router management to the open internet unless you have a specific need and understand the risks.

Guest WiFi is worth using for visitors and smart-home devices that do not need access to laptops, NAS devices, or other trusted systems. NETGEAR Armor can add extra network-level protection, but it is subscription-based after any trial and should not be treated as a substitute for patched devices, strong passwords, and sensible network segmentation.

Pros

• Supports WiFi 7 with BE3600 dual-band wireless
• 2.5Gbps WAN port gives headroom for faster internet connections
• WPA3, guest WiFi, VPN support, and automatic firmware updates
• NETGEAR Armor integration for optional added security features
• App and web-based management options
• Compact design with internal antennas
• Sensible fit for small-to-midsize homes
• Rated for up to 2,000 sq. ft. and up to 50 devices
• Works with most cable, fiber, and DSL setups when paired with the right modem or gateway

Cons

• No built-in modem
• No 6GHz band, despite being a WiFi 7 router
• Four LAN ports are Gigabit only
• No multi-gig LAN port for a desktop, NAS, or wired switch
• Not ideal for large homes or difficult coverage layouts
• NETGEAR Armor requires a subscription after any trial
• Less compelling for users who already own a strong WiFi 6E or premium WiFi 6 router

When Not to Buy

Do not buy the RS90 if you need a modem-router combo. It has no coax input and cannot directly replace a cable modem.

Skip it if you are buying WiFi 7 specifically for 6GHz. The RS90 is dual-band only, so WiFi 6E and tri-band WiFi 7 clients will not get a 6GHz network from this router.

It is also the wrong choice if your wired network needs multi-gig speeds. The 2.5Gbps port is for internet/WAN, while the LAN ports are limited to Gigabit Ethernet.

For larger homes, homes with heavy construction materials, or layouts where one router struggles to reach every room, a mesh system may be a better fit. For gaming-focused setups, high-end local file transfers, or advanced network labs, a more powerful router with multi-gig LAN and tri-band WiFi will make more sense.

Who Should Buy

The RS90 is a good fit for buyers who want a straightforward router upgrade with modern WiFi, better baseline security, and simple management. It is especially suitable for:

• Small-to-midsize homes
• Apartments and townhouses
• Households upgrading from older WiFi 5 routers
• Users who want WPA3 and automatic firmware updates
• Homes with mostly wireless devices
• Internet plans around gigabit or somewhat above
• Buyers who already have a separate modem or ISP Ethernet handoff
• Users who prefer app-guided setup but still want a web interface available

It is best understood as a mainstream WiFi 7 router with security features, not a no-compromise enthusiast platform.

Final Verdict Rationale

The NETGEAR Nighthawk RS90 is a practical entry point into WiFi 7 for buyers who want a modern, easy-to-manage router without moving into high-end networking gear. Its 2.5Gbps WAN port, WPA3 support, automatic firmware updates, guest WiFi, VPN support, and optional NETGEAR Armor service make it a sensible upgrade for everyday home networks.

Its limitations are significant but clear. The lack of 6GHz keeps it from delivering the full tri-band WiFi 7 experience, and the Gigabit-only LAN ports make it a poor choice for multi-gig wired setups. It is also not a modem, so buyers need the right upstream hardware from their ISP.

For a small-to-midsize home with mostly wireless devices, the RS90 is a balanced, security-conscious router upgrade. For power users, large homes, and anyone chasing the biggest WiFi 7 performance gains, it is too constrained.
