The ASUS TUF Gaming BE9400 is a tri-band Wi-Fi 7 router built for gamers and multi-gigabit homes. Its headline features are four 2.5GbE ports—including a dedicated gaming-priority LAN port—plus 6GHz Wi-Fi, 320MHz channels, 4K-QAM, MLO, AiMesh, and ASUS gaming software. Its “BE9400” rating means up to 9,400Mbps combined theoretical wireless throughput, not a 9.4Gbps connection for one device.
Regional launch evidence confirms Singapore and Australian availability signals, but the reviewed reporting does not establish a U.S. price or retail launch.

The wireless figures come from the product’s advertised class rating. They are theoretical PHY-rate totals across three bands, not guaranteed internet speeds, file-transfer speeds, or a single-device 9.4Gbps link. Actual performance depends on the client, distance, channel width, interference, radio regulations, and the capabilities of the wired network.

What the dedicated gaming port actually does
One of the three LAN ports is designated as a gaming port. Connect a gaming PC, PlayStation, Xbox, or other wired gaming device to it, and the router prioritizes that device’s traffic without requiring additional configuration, according to the product listing.
That makes the port a convenience-focused traffic-prioritization feature. It is not a separate internet connection, a faster modem, or a guarantee of lower ping. It does not increase the speed of an internet subscription and cannot correct latency caused by an ISP route, a distant game server, a congested modem or optical network terminal, poor game-server performance, or bufferbloat upstream from the router.
The feature is most useful when a wired gaming device shares the connection with people streaming video, downloading large files, or uploading content. If the gaming device is the only heavy user, there may be little congestion for the port to solve. The benefit is also less direct when the console or PC connects over Wi-Fi rather than the designated LAN port.

For wireless gaming, router placement, a clean 5GHz or 6GHz connection, a compatible Wi-Fi 7 client, and—where practical—Ethernet backhaul for mesh nodes can matter more than the label on a LAN socket.
Wi-Fi 7 features: 320MHz, 4K-QAM, and MLO
320MHz channels
Wi-Fi 7 can use channels up to 320MHz wide, primarily in the 6GHz band. Wider channels can increase link rates, but the full benefit requires a compatible Wi-Fi 7 client, permitted 6GHz operation in the buyer’s country, supported channels, a relatively clean radio environment, and a short enough distance from the router.
Rank #2
- Blazing-fast WiFi 7 boosts tri-band throughput up to 12000 Mbps with 320 MHz channels of 6 GHz band, Multi-Link Operation (MLO) and 4K-QAM
- Powerful wired network capacity of up to 20G with one 2.5G WAN port and seven 2.5G LAN ports.
- High-performance quad-core 2.0GHz CPU with robust cooling, 2GB RAM and eight internal antennas providing up to 3000 sq. ft. of range.
- Smart Home Master makes it easy to set up functional subnetwork (up to 3 SSIDs) for IoT devices and VPNs
- ROG-exclusive Gaming Network streamlines Triple-Level Game Acceleration setup and connections through convenient SSIDs
6GHz also generally has shorter range and weaker wall penetration than 5GHz. A 320MHz connection that works well in the same room may fall back to a narrower channel or a lower band farther away.
4096-QAM
4K-QAM increases the amount of data encoded in each transmission when signal quality is strong. It can improve peak link rates under favorable conditions, but it is not a universal speed boost. Distance, walls, interference, and client support determine whether a device can use the higher modulation level.

Multi-Link Operation
MLO allows compatible Wi-Fi 7 clients to use multiple links according to the mode supported by both the router and client. It can help with throughput, responsiveness, or connection resilience, but not every device combines the same bands or links. The retailer specifically notes that supported MLO modes and bands vary by client.
Older Wi-Fi 6 and Wi-Fi 6E devices can connect to the router, but they will not receive every Wi-Fi 7 benefit. Buyers should therefore check the wireless hardware in their gaming PC, phone, laptop, and console rather than assuming that purchasing a Wi-Fi 7 router makes existing devices Wi-Fi 7-capable.
Gaming and network-management features
The BE9400’s value is not limited to its radio hardware. Reported software features include:
Rank #3
- WiFi 7 Gaming Router - WiFi 7 (802.11be) dual-band gaming router boosts speeds up to 6500 Mbps, with 4096-QAM increasing a single frequency band's transmission speed by 1.2 times.

- Mobile Game Mode: a one-tap option in the ASUS Router app for prioritizing mobile-game traffic.
- Adaptive QoS: tools for prioritizing and filtering different categories of network traffic.
- AiMesh: lets the router join a compatible ASUS mesh system. Ethernet backhaul is preferable where available because wireless backhaul consumes airtime and can reduce throughput.
- Smart Home Master: separate network profiles or SSIDs for use cases such as IoT devices, children, VPN traffic, and MLO.
- AiProtection: network-security and device-protection functions.
- Parental controls: the retailer describes these as available without a subscription, although features can vary by firmware and region.
- Instant Guard: ASUS’s remote-access VPN feature. The product listing says it requires a public IPv4 WAN address, so users behind carrier-grade NAT may not be able to use it as described.
The USB-A port is listed for storage sharing, printer sharing, and 4G/5G tethering. These functions are useful for basic home-network services, but they do not turn the router into a high-performance NAS.

All four Ethernet ports are rated at 2.5Gbps: one for WAN and three for LAN. That is a strong arrangement for a typical 1Gbps-to-2.5Gbps household, especially one with multiple wired PCs, consoles, access points, or network storage devices.
The limitation is the 2.5Gbps WAN ceiling. A subscriber with 5Gbps, 8Gbps, or 10Gbps service cannot use a single connection through this router to its full potential. The BE9400 can still provide useful local multi-gigabit networking and fast wireless links, but buyers seeking maximum internet throughput should compare it with routers offering 10GbE WAN connectivity.
Its BE9400 wireless rating should not be compared directly with a router’s 10GbE port as though the numbers measured the same thing. One is an aggregate theoretical radio-class rating; the other describes a wired interface ceiling.
Coverage and hardware claims
Reported hardware includes a 1.5GHz quad-core processor, 1GB of DDR4 memory, six fixed antennas, and a double-heatsink design. ASUS’s TUF positioning also includes durability testing claims involving humidity, I/O, stress, and electromagnetic-interference testing.

- Tri-Band WiFi 7 AI Gaming Router - 320MHz channels in the 6GHz band and 4096-QAM significantly increase network capacity and throughput, with speeds of up to 19 Gbps.
- Ultimate Wired Bandwidth - Wired network capacity up to 31G with dual 10G ports, four 2.5G ports, and extreme 20G Link Aggregation
- AI Game Boost - A Triple-Level AI Acceleration Engine with Adaptive QoE at its core, AI and DPI work together to reduce ping, jitter, and packet loss. Preconfigured modes let users prioritize bandwidth in one click for a faster, smoother gaming experience.
The approximately 2,500-square-foot coverage figure is a manufacturer or retailer claim, not an independent measurement. Real coverage depends on walls, floors, building materials, neighboring networks, client antennas, router placement, regional transmit-power limits, and whether AiMesh nodes are used. A large or multi-story home should not assume that one router will deliver strong 6GHz coverage everywhere.
Price and availability
Regional information is more concrete than U.S. launch information:
- Singapore: HardwareZone reported a price of S$329 and availability toward the end of October 2025.
- Australia: PB Tech listed the router at A$406.89 and showed it as available on order.
- United States: the reviewed sources did not confirm a U.S. retail price or availability.
These are regional retail signals, not a U.S. MSRP. Exchange rates, taxes, import costs, warranty coverage, power-adapter compatibility, and return policies can materially change the final cost. Buyers importing the router should verify country-specific firmware, authorized warranty support, shipping charges, and applicable taxes before ordering.

The ASUS TUF Gaming BE6500 is a cheaper dual-band Wi-Fi 7 alternative in the same retailer ecosystem. It lacks the BE9400’s 6GHz band and lower wireless capacity, making it more appropriate for buyers who want Wi-Fi 7 without needing tri-band operation.
TP-Link’s Archer BE550 is another tri-band Wi-Fi 7 option. The listed model has five Ethernet ports, including 2.5GbE connectivity, and a BE9300-class rating. It may appeal to buyers who value port count or the TP-Link ecosystem, while ASUS users planning an AiMesh system may prefer the BE9400.
Best Value
- Beyond-fast WiFi 7 (802.11be) - WiFi 7 (802.11be) dual-band extendable router boosts speeds up to 3600 Mbps, with 4096-QAM increasing a single frequency band’s transmission speed by 1.2 times
- Unleashing Multi-link operation (MLO) for Ultra-Smooth Connectivity - Link to multiple bands at the same time to ensure stable internet connections and efficient data transfers
- Versatile WAN configuration options - Establish always-on internet through AI WAN detection and a convenient USB port ready for 4G LTE and 5G Mobile tethering.
- Smart Home Master - Easily establish up to three SSIDs with Smart Home Master for easy IoT device setup and management, instant VPN connections, and convenient parental controls.
- Commercial-Grade network security - Network security with commercial-grade AiProtection Pro powered by Trend Micro, plus a one-tap security scan and Safe Browsing.
The TP-Link Deco BE65 is a mesh-oriented tri-band Wi-Fi 7 alternative with a higher BE11000-class rating, four Ethernet ports, USB, and a one-pack configuration in the listed product information. It is the more natural comparison for buyers prioritizing whole-home mesh deployment rather than ASUS’s gaming-specific features.
At the high end, ASUS ROG models such as the ROG Rapture GT-BE98 offer a more premium feature and multi-gigabit positioning, but the reported PB Tech listing placed that model at A$1,258.08—far above the BE9400. For an ordinary 1Gbps-to-2.5Gbps home, the extra expense may not produce a visible gaming improvement.
Who should consider the ASUS TUF Gaming BE9400?
The BE9400 makes the most sense for:
- Wi-Fi 7 early adopters with internet service up to 2.5Gbps.
- Gamers who can connect a PC or console by Ethernet.
- Homes needing several 2.5GbE connections.
- Users who want 6GHz capacity for compatible devices.
- ASUS owners planning to expand with AiMesh.
- Households that value built-in QoS, IoT separation, VPN, security, and parental-control tools.
It is a weaker fit for:
- 5Gbps-to-10Gbps subscribers who need a faster WAN port.
- Buyers whose devices are almost entirely Wi-Fi 6 or older.
- Large homes that need extensive coverage but are not prepared to add mesh nodes.
- Buyers seeking independently tested range, throughput, or latency results.
- Anyone who needs confirmed U.S. pricing, stock, and warranty support before purchasing.
Bottom line
The ASUS TUF Gaming BE9400 is best understood as a feature-rich 2.5GbE-class Wi-Fi 7 router, not as a 9.4Gbps internet gateway. Its tri-band design, 6GHz support, four 2.5GbE ports, AiMesh compatibility, and dedicated wired gaming port make it a compelling fit for gamers and multi-gigabit homes within that speed range.
The gaming port is useful because it prioritizes a wired device, but it is not a revolutionary latency fix. The buying decision should come down to four questions: do you have Wi-Fi 7 clients, do you need 6GHz and tri-band capacity, is your internet service 2.5Gbps or slower, and is the model officially supported in your region?
