Overview
The ASUS RT-BE55 is a dual-band Wi-Fi 7 router designed for home networks, connected-device environments, and small offices requiring modern wireless connectivity with multi-gigabit WAN support. It supports IEEE 802.11be and delivers a combined theoretical wireless rate of up to 3,600 Mbps across the 2.4 GHz and 5 GHz bands.
The router supports rates of up to 688 Mbps on 2.4 GHz and 2,882 Mbps on 5 GHz. Wi-Fi 7 features include Multi-Link Operation (MLO), 4096-QAM, OFDMA, and channel bandwidths up to 160 MHz. Four external antennas and 2×2 transmit/receive configurations support wireless connectivity across both bands.
Wired connectivity includes one 2.5 Gigabit WAN port for an internet connection or supported wired backhaul configuration, plus four Gigabit Ethernet LAN ports for computers, switches, smart TVs, and other network devices. The router supports ASUS AiMesh, allowing it to operate as a primary router or as a node in a compatible mesh network.
ASUS networking software provides AiProtection security, VPN client and server capabilities, guest networks, parental controls, adaptive QoS, traffic monitoring, and device-management tools through the ASUS Router app or web interface. The RT-BE55 is a dual-band router without a 6 GHz radio, so it does not provide 6 GHz Wi-Fi connectivity.

Product Note
The BE3600 rating is a combined theoretical wireless rate, not the expected throughput of one device. Actual performance depends on client capabilities, signal conditions, interference, network load, and internet service speed. The 2.5GbE port is the WAN interface; the four LAN ports are Gigabit Ethernet, which may limit wired throughput for connected devices. The router does not have a 6 GHz band or a USB port. Confirm regional specifications, firmware-supported features, and warranty terms with the supplier before ordering.
