ASUS TUF Gaming BE9400 Tri-Band WiFi 7 Gaming Router

Technical Specifications

Product Description

The ASUS TUF Gaming BE9400 is a military-grade, tri-band WiFi 7 gaming router engineered for competitive multiplayer gamers, livestreamers, 8K multimedia streamers, and smart home power users requiring sustained performance under extreme network loads. Built within the signature TUF Gaming ethos, the router features a matte black industrial chassis with rugged angular lines, heat-dissipating metallic grilles, and precision-engineered internal heatsinks. Rigorously tested for physical durability and thermal stability, the system uses high-gain multi-angle external antennas equipped with universal beamforming to blanket spaces up to 2,500 square feet with reliable, wall-penetrating wireless signals.

Under the hood, the router is powered by a 1.5 GHz 64-bit quad-core processor paired with 1GB of high-speed DDR4 RAM and 256MB of onboard flash storage. This hardware architecture allows the system to route massive multi-device data flows, maintain active stateful packet inspection, and handle encrypted VPN tunnels without thermal throttling or jitter. Utilizing the IEEE 802.11be WiFi 7 standard across 2.4 GHz, 5.0 GHz, and pristine 6.0 GHz frequency spectrums, the TUF-BE9400 delivers aggregated wireless speeds of up to 9400 Mbps—comprising 5764 Mbps on the 6 GHz band, 2882 Mbps on the 5 GHz band, and 688 Mbps on the 2.4 GHz band. WiFi 7 technologies such as Multi-Link Operation (MLO), 4096-QAM (4K-QAM), and ultrawide 320 MHz channels on the 6 GHz band maximize wireless throughput and lower latency for smooth 8K streaming and cloud gaming.

Wired connectivity is built around multi-gigabit throughput, featuring one dedicated 2.5 Gbps WAN port and three 2.5 Gbps LAN ports. Among these, a dedicated Gaming Port automatically prioritizes connected gaming PCs or next-generation consoles without requiring manual setup. The router supports Dual WAN failover and load balancing to prevent ISP drops, while a high-speed USB 3.2 Gen 1 port enables 4G/5G mobile hotspot backup tethering, Download Master unattended downloads, and network storage via built-in Samba and FTP servers. Deployment flexibility is reinforced by five distinct operational modes: Wireless Router, AiMesh Node, Access Point, Range Extender, and Media Bridge.

Gaming traffic is prioritized across all fronts with hardware Game Acceleration, Mobile Game Mode via the ASUS Router app to eliminate lag on handheld devices, and OpenNAT profile configuration. Network security is anchored by commercial-grade protection, including a built-in Security Scan engine, Denial of Service (DoS) protection, SPI firewall, and malicious site filtering. For secure remote networking, the router integrates advanced VPN capabilities with native support for OpenVPN Client/Server, WireGuard, Surfshark, and NordVPN, alongside ASUS Instant Guard for encrypted public Wi-Fi tunnels. Completed with advanced parental controls featuring URL and keyword filters, Adaptive QoS, Bandwidth Limiting, System Event Logging, and full AiMesh mesh expandability, the ASUS TUF-BE9400 provides a resilient and future-proof WiFi 7 gaming foundation backed by a 3-year ASUS warranty.
