Verdict

The ASUS RP-AX56 is an AX1800 dual-band Wi-Fi 6 range extender delivering total speeds up to 1800 Mbps, with 1201 Mbps on the 5GHz band and 574 Mbps on the 2.4GHz band. It features a 2x2 antenna configuration with 80MHz bandwidth support and includes a single Gigabit Ethernet port for wired backhaul or connecting stationary devices. Key advantages include its seamless integration into ASUS AiMesh systems for whole-home coverage under a single SSID, easy mobile app setup, and support for the latest WPA3 security protocol. However, notable drawbacks include its lack of 160MHz channel support, a bulky design that can block adjacent power outlets, and the absence of a pass-through AC outlet.
