ASUS RT-AX5400 WiFi 6 Router

The ASUS RT-AX5400 is a dual-band WiFi 6 wireless router designed for homes and small businesses needing high throughput. It delivers AX5400 class speeds with 574 Mbps on the 2.4 GHz band and 4804 Mbps on the 5 GHz band. Four external non-detachable antennas provide coverage across the space. A single USB 3.2 Gen 1 port allows for network storage or printer sharing.

Suits busy networks needing VPN flexibility

This router suits households or small offices running many simultaneous devices and requiring advanced VPN options. It supports multiple client and server protocols including WireGuard, OpenVPN and IPSec, plus VPN Fusion for split tunnelling. Buyers who need multi-gigabit WAN ports beyond 1 Gbps or built-in modem functionality should look at other products.

Simple setup via app or web interface

Initial configuration is handled through the ASUS Router mobile app for guided setup or via the detailed web dashboard for advanced control. The WAN port accepts standard 10/100/1000M Ethernet connections. Common issues include placing the unit where antenna orientation is restricted or overlooking firmware updates that enable the latest security and VPN features.

Questions about this item

What internet connection speed do I need to use the 1000 Mbps WAN port?

The WAN port supports up to 1000 Mbps, so any broadband plan at or below that rate will work without bottlenecking the router.

Can I keep using my existing AiMesh-compatible router to extend coverage?

Yes, the RT-AX5400 works with any AiMesh-compatible router, letting you add it to your current mesh for seamless roaming.

How can I verify the router is delivering the 574 + 4804 Mbps link rates after setup?

Check the ASUS Router app or web dashboard for the negotiated PHY rates on the 2.4 GHz and 5 GHz bands; they should show 574 Mbps and 4804 Mbps respectively when clients connect at maximum capability.
