Overview
The ASUS RT-BE88U is a BE7200-class dual-band Wi-Fi 7 router designed for high-performance home networks, gaming, content production, and small-office environments requiring extensive wired connectivity. It supports IEEE 802.11be and delivers theoretical wireless rates of up to 1,376 Mbps on 2.4 GHz and 5,764 Mbps on 5 GHz, for a combined advertised rate of approximately 7,200 Mbps.
Wireless capabilities include Multi-Link Operation (MLO), 4096-QAM, OFDMA, beamforming, and channel bandwidths up to 160 MHz. Four detachable external antennas support 4×4 transmit/receive configurations on both frequency bands. The router operates on 2.4 GHz and 5 GHz and does not include a 6 GHz radio.
The RT-BE88U provides extensive wired networking options, including one 10GbE RJ45 WAN/LAN port, one 10Gbps SFP+ port, one configurable 2.5GbE WAN/LAN port, three 2.5GbE LAN ports, and four Gigabit Ethernet LAN ports. This connectivity supports multi-gigabit internet services, network-attached storage, high-speed workstations, and flexible WAN configurations. Depending on port assignments, the router can provide up to nine LAN connections.
A USB 3.2 Gen 1 port supports compatible storage applications and 4G/5G mobile tethering. Network features include ASUS AiMesh, AiProtection Pro, Guest Network Pro, VPN Fusion, VPN client and server functions, parental controls, adaptive QoS, and traffic monitoring. VLAN support and network segmentation help separate IoT, guest, and other device groups. Management is available through the ASUS Router app and ASUSWRT web interface.

Product Note
The BE7200 classification represents combined theoretical wireless rates across the two frequency bands, not guaranteed single-device throughput. The RT-BE88U does not support 6 GHz Wi-Fi. Its 10GbE RJ45, SFP+, 2.5GbE, and Gigabit interfaces provide substantial wired capacity, but available WAN/LAN assignments depend on the selected configuration. SFP+ connectivity requires a compatible transceiver or direct-attach cable, as applicable. VPN, USB storage, and mobile-tethering functions depend on compatible equipment and firmware. Confirm regional specifications, power-adapter details, warranty coverage, and package contents with the supplier before ordering.
