Dual-band WiFi 7 router with 3600 Mbps

The ASUS RT-BE55 is a dual-band WiFi 7 router delivering wireless speeds up to 3600 Mbps. It includes a 2.5G WAN port and four Gigabit LAN ports for wired devices. Four external antennas and AiProtection security support home and small-office networks.

Suits homes wanting WiFi 7 and simple mesh expansion

Buyers needing multi-gigabit LAN ports beyond the single 2.5G WAN connection should consider other models. Households requiring tri-band operation or more than three separate SSIDs for IoT segregation will not find those features here.

Handles 3600 Mbps dual-band throughput

The router comfortably manages 8K streaming, cloud gaming and multiple simultaneous devices using 4K-QAM and MLO. Wired backhaul is limited to 2.5 Gbps on the WAN side and 1 Gbps on each LAN port, so multi-gigabit local transfers will saturate the LAN interfaces.

Questions about this item

Does the RT-BE55 need a modem with a 2.5G Ethernet port to reach its maximum WAN speed?

The router has one 2.5G WAN port; it will work with any modem that provides a 10/100/1000M or 2.5G RJ-45 connection, but full 2.5G throughput requires a modem or ONT that also supports 2.5G.

Will my Wi-Fi 6 devices connect to the RT-BE55 without losing features like WPA3 or parental controls?

Yes, the router supports IEEE 802.11ax and earlier standards, so Wi-Fi 6 devices join the network and still benefit from WPA3 security, AiProtection filtering, and the three SSID options for IoT or parental control.

How can I confirm the RT-BE55 is delivering Wi-Fi 7 speeds after setup?

Connect a Wi-Fi 7 client, open the ASUS router app or web UI, and check the client list — it will show a 5 GHz link rate up to 3600 Mbps with MLO and 160 MHz channel width when the connection is operating at full Wi-Fi 7 capability.
