ASUS RT-AX1800S vs NETGEAR Nighthawk RS90: Budget WiFi 6 or Future-Proof WiFi 7

The ASUS RT-AX1800S and the NETGEAR Nighthawk RS90 sit at opposite ends of the home router market. One is a low-cost WiFi 6 workhorse built for tight budgets, the other a WiFi 7 model with modern ports and more headroom. This comparison breaks down the differences that actually change a buying decision, so the reader can pick one and move on to the checkout page.

The short version: the ASUS suits smaller homes and price-sensitive buyers who want solid everyday coverage. The NETGEAR suits households with lots of devices, fast internet plans, and an interest in staying current for years. The table below covers the picks, and the sections after it explain each difference.

The Picks at a Glance

Product	Key Spec	Best Use	Price Tier
ASUS RT-AX1800S	Dual Band WiFi 6, AiMesh Compatible	Budget coverage for small to mid-size homes	Budget
NETGEAR Nighthawk RS90	Dual Band WiFi 7, BE3600, 2.5G port	Dense device loads and fast internet plans	Mid-range

ASUS RT-AX1800S

Wireless Standard: WiFi 6 (802.11ax)
Bands: Dual Band
Mesh: AiMesh Compatible
Security: Subscription-Free Network Security
Features: Parental Control, Built-in VPN
Use Case: Gaming, Streaming, Smart Home

The ASUS RT-AX1800S is a dual-band WiFi 6 router aimed at buyers who want modern wireless without paying a premium. Its subscription-free security package means the router’s protective features do not turn into a recurring bill, which is a real advantage at this price. Built-in VPN support and parental controls add utility that budget routers often strip out.

AiMesh compatibility is the sleeper feature here. A buyer who starts with one unit can add another AiMesh node later and build a mesh network without replacing the original router. For a small apartment or a single-floor home, one unit covers the basics: streaming, gaming, and a house full of smart home devices.

Trade-off: The dual-band design and modest throughput mean this router is not the right fit for large multi-story homes or households running many heavy devices at once, where coverage gaps and congestion are likely.

NETGEAR Nighthawk RS90

Wireless Standard: WiFi 7 (BE3600)
Bands: Dual Band
Ports: 1× 2.5G + 3× Gigabit
Device Capacity: 50 devices
Coverage: Up to 2,000 sq ft
Speed Rating: 3.6 Gbps

The NETGEAR Nighthawk RS90 is a WiFi 7 router built for households that have outgrown entry-level hardware. Its 2.5G port is the standout spec: it can feed a fast cable or fiber plan without the port becoming the bottleneck, and it gives a wired device a much quicker connection than standard Gigabit.

The device rating of 50 and coverage of up to 2,000 square feet put it in comfortable territory for a family home with phones, laptops, TVs, and smart devices all fighting for airtime. WiFi 7 is also a forward-looking choice — buyers who plan to keep a router for several years get a standard that newer laptops and phones are already adopting.

Trade-off: WiFi 7 only pays off when the connected devices support it, so buyers with older hardware will see much of the extra capability go unused, and the higher price buys headroom rather than an immediate jump in everyday speed.

Wireless Standard and Speed

The clearest split is the wireless generation. The ASUS runs WiFi 6, a mature standard that handles streaming and gaming well on a normal home connection. The NETGEAR runs WiFi 7 with a stated 3.6 Gbps rating, a newer standard with more capacity for dense device loads and faster local transfers.

For most buyers on a mid-tier internet plan, WiFi 6 is enough. The NETGEAR’s advantage shows up when the internet plan is fast, when many devices connect at once, or when the buyer wants the router to last through the next hardware upgrade cycle. Verdict: NETGEAR wins on raw capability, ASUS wins on value.

Wired Ports

The NETGEAR’s 2.5G port is a genuine differentiator. It lets a fast plan reach the router at full speed and gives a wired desktop or NAS a quicker link. The ASUS relies on standard Ethernet ports, which are fine for typical home plans but cap out lower. Verdict: NETGEAR.

Coverage and Device Load

The NETGEAR states coverage up to 2,000 square feet and support for 50 devices, which points to a family home with plenty of connected hardware. The ASUS does not publish those figures in its name, but its dual-band design and budget positioning suggest a smaller footprint. Verdict: NETGEAR for larger homes, ASUS for compact spaces.

Mesh and Expandability

The ASUS carries AiMesh compatibility, so a buyer can add nodes and grow coverage over time without a full replacement. The NETGEAR’s name does not advertise a mesh system, so buyers who expect to expand should confirm that capability before committing. Verdict: ASUS.

Security and Parental Controls

The ASUS bundles subscription-free network security, parental controls, and a built-in VPN. That combination is unusual at the budget end and saves money over time. The NETGEAR’s name does not list comparable features, so buyers who prioritize built-in protection should check the details. Verdict: ASUS.

Which Should You Buy?

Choose the ASUS RT-AX1800S if: the budget is tight, the home is small to mid-size, and the priority is reliable WiFi 6 with no recurring security subscription. It also suits buyers who want to start with one unit and add AiMesh nodes later.

Choose the NETGEAR Nighthawk RS90 if: the household has many devices, the internet plan is fast enough to benefit from a 2.5G port, and the buyer wants a router that will not need replacing when WiFi 7 devices become common. It is the better pick for larger homes and heavier loads.

FAQ

1. Is WiFi 7 worth it over WiFi 6 right now?
   It depends on the devices. WiFi 7 routers like the NETGEAR RS90 offer more capacity and a faster wired port, but the full benefit arrives as more phones and laptops ship with WiFi 7 support. Buyers who keep routers for years get more value from it.

2. Does the ASUS RT-AX1800S support mesh networking?
   Yes. It is AiMesh compatible, so additional AiMesh nodes can be added to extend coverage without replacing the main router.

3. What does the 2.5G port on the NETGEAR RS90 do?
   It provides a wired connection faster than standard Gigabit, useful for fast internet plans and for wired devices like a desktop or network storage.

4. Which router is better for a large house?
   The NETGEAR RS90, with its stated coverage up to 2,000 square feet and 50-device rating, is the more suitable starting point. Very large or multi-story homes may still need additional coverage.

5. Do either of these routers charge a subscription?
   The ASUS advertises subscription-free network security. The NETGEAR’s name does not state subscription terms, so buyers should confirm before purchase.

6. Which is the better value?
   The ASUS is the budget pick and delivers WiFi 6, mesh support, and built-in security for less. The NETGEAR costs more but buys WiFi 7, faster ports, and more capacity.

7. Can the ASUS handle gaming and streaming?
   Yes. Its name lists gaming and streaming among its intended uses, and WiFi 6 is sufficient for both on a typical home connection.

Bottom Line

The ASUS RT-AX1800S is the pick for buyers who want dependable WiFi 6, mesh expandability, and subscription-free security without stretching the budget. The NETGEAR Nighthawk RS90 is the pick for households that need more device capacity, a faster wired port, and a router built to last through the WiFi 7 transition.
