Netgear Nighthawk AX5400 (RAX50) vs TP-Link Archer AX73: Which Mid-Range WiFi 6 Router Wins?

The Netgear Nighthawk AX5400 (RAX50) and TP-Link Archer AX73 compete for exactly the same buyer: someone upgrading from an aging WiFi 5 router who wants genuine WiFi 6 performance without paying flagship prices. Both are AX5400 dual-band routers running the same Broadcom BCM6750 tri-core 1.5 GHz processor with 512 MB of RAM. On paper, they look nearly identical. In practice, the Archer AX73 wins on every differentiating factor that actually matters for a typical home — and it costs less.

Antenna Count: Six vs Four

The Archer AX73’s six external high-gain antennas are a meaningful hardware advantage over the RAX50’s four. More antennas allow for more aggressive beamforming — the router directs signal energy more precisely toward your devices rather than radiating it uniformly in all directions. In real-world testing at distances beyond 50 feet or through one to two interior walls, the AX73 typically sustains 600–800 Mbps on the 5 GHz band, while the RAX50 lands in the 550–720 Mbps range under comparable conditions. The gap is modest but consistent across independent reviews. At close range (same room or adjacent rooms), both routers deliver comparable results and the antenna count difference is negligible.

Both routers support MU-MIMO and OFDMA on their 5 GHz radios, which matters when multiple devices are uploading and downloading simultaneously. For a deeper look at how these WiFi 6 technologies work together, see our explainer on OFDMA in WiFi 6.

OneMesh vs No Mesh: A Future-Proofing Gap

This is the most consequential difference between these two routers. The Archer AX73 supports TP-Link’s OneMesh system, which means you can add any compatible TP-Link extender or access point to create a unified mesh network with a single SSID and seamless roaming. If your home develops dead zones after six months, you add a node — you do not replace the router.

The Netgear RAX50 has no mesh expansion capability. It is a standalone router. If 2,500 sq ft of rated coverage falls short in your specific home due to concrete walls, multiple floors, or a long layout, your only options are a separate WiFi extender (which creates a secondary SSID and adds roaming friction) or replacing the RAX50 entirely. Over a typical three-to-four-year router lifespan, that inflexibility is a genuine hidden cost. Our guide on repeaters vs access points vs mesh systems explains when expandability becomes essential — and the RAX50 forces you down the repeater path while the AX73 avoids it entirely.

Security Costs: HomeShield Free vs Armor Subscription

Both routers ship with network security features, but the pricing models diverge significantly after the first year.

The TP-Link Archer AX73 includes HomeShield with a genuinely useful free base tier: malicious site blocking, network scanning, and basic traffic monitoring at no cost, indefinitely. The paid HomeShield Pro tier (~$55/year) adds advanced parental controls, real-time IoT device protection, and detailed usage reports — but most households can operate comfortably on the free tier alone.

The Netgear RAX50 offers Netgear Armor, powered by Bitdefender, which includes advanced threat detection, a VPN client, and multi-device antivirus. The problem is cost: Armor requires an active paid subscription after the initial 30-day trial, at $99.99 per year. Over three years, that adds $300 to the RAX50’s effective cost — more than twice the router’s purchase price. Basic WPA3 support and guest network isolation remain available without Armor, but the malware detection and intrusion prevention disappear when the subscription lapses. For households that skip the subscription entirely, the RAX50’s security story is thinner than the AX73’s free tier. See our guide on WPA2 vs WPA3 security for a full breakdown of what router-level security can and cannot protect.

Real-World Throughput

Given identical Broadcom BCM6750 processor and radio hardware, throughput at short range is predictably close. Both routers reliably deliver 850–950 Mbps on 5 GHz at close range to a WiFi 6 client. At mid-range (one wall, 40–50 feet), both settle between 550–750 Mbps. The AX73’s six-antenna configuration provides a slight but consistent edge at distance.

WAN Bottleneck on Multi-Gig Plans

Neither router supports multi-gig WAN. Both cap at Gigabit on the WAN port, meaning any internet plan faster than 1 Gbps is bottlenecked before it reaches your devices. If you are on a 1.2 Gbps or 2 Gbps fiber plan, neither router is the right buy — look instead at options with 2.5G WAN ports like the TP-Link Archer AX5400 Pro or the ASUS RT-AX88U Pro. Run a speed test to confirm your current plan speed before deciding whether the Gigabit WAN is actually a constraint for you. Our guide on router WAN port bottlenecks explains how to identify when your router is the limiting factor.

On 2.4 GHz, the RAX50 holds a slight theoretical edge (600 Mbps vs 574 Mbps), but real-world performance on 2.4 GHz is similar for both — around 150–200 Mbps at range, appropriate for smart home and IoT devices. Neither router excels on 2.4 GHz at distance, which is true of most AX5400-class hardware.

Who Should Buy the RAX50 Instead?

The Netgear RAX50 makes sense in a few specific scenarios:

• App preference: The Nighthawk app is smoother and more feature-complete than TP-Link’s Tether app. For users who manage their network primarily from a smartphone, the Netgear experience is marginally better.
• More flash storage: The RAX50’s 256 MB of flash (vs 128 MB on the AX73) provides more headroom for ReadySHARE USB storage features and potential third-party firmware customization.
• Deep discounts: The RAX50 occasionally drops to $99–$119 on sale. At that price it represents strong value, and the mesh and security caveats are easier to overlook.
• Existing Netgear ecosystem: If you already own Netgear managed switches or have other Nighthawk hardware, staying in-brand avoids a management learning curve.

Verdict

At comparable prices, the TP-Link Archer AX73 wins clearly. Six antennas, OneMesh expandability, a no-cost HomeShield security tier, and a $20–$30 price advantage make it the smarter purchase for the vast majority of mid-range WiFi 6 buyers. Both routers deliver AX5400 throughput from identical core hardware, but the AX73 costs less upfront, grows with your home more gracefully via OneMesh, and does not charge you $100/year to keep network security active. The RAX50’s only real advantages — more flash storage and a cleaner app — rarely matter in daily use. Unless you find the RAX50 at a steep discount or specifically need the Nighthawk ecosystem, the Archer AX73 is the clear choice at this price tier. For households that expect to outgrow a single router, it’s not even close.
