ASUS ZenWiFi BD4 1-Pack White WiFi 7 Dual-Band Mesh Router
The ASUS ZenWiFi BD4 1-Pack WiFi 7 Dual-Band Mesh Router is designed for homeowners who want whole-home WiFi 7 coverage without running a dedicated wired network throughout every room. It combines Multi-Link Operation, AiMesh support, and dual 2.5G Ethernet ports to address dead zones and bandwidth bottlenecks in medium to large homes.
Why this product
WiFi 7 with MLO on both bands
Multi-Link Operation works with all WiFi 7 devices regardless of which MLO mode they use — simultaneous or alternating — combining or switching between 2.4 GHz and 5 GHz for more stable throughput.
Dual 2.5G ports for wired backhaul
Two 2.5G WAN/LAN ports with auto-detection let you run a wired backhaul between mesh nodes, supporting up to 2.5 Gbps connections between units rather than relying on wireless backhaul alone.
160 MHz channel support
Ultrawide 160 MHz channels allow higher data transfer rates and reduced latency compared to 80 MHz operation, making it better suited to bandwidth-intensive tasks like 8K streaming and HDR gaming.
AiMesh scales to cover larger homes
Built-in AiMesh support allows this unit to act as a primary router or a node, with coverage up to 6,500 sq. ft. in a 3-pack configuration and compatibility with a wide range of other ASUS AiMesh routers.
Commercial-grade AiProtection Pro included
AiProtection Pro provides 24/7 network security including malicious site blocking, two-way IPS, and infected device prevention — no separate subscription is listed in the product record.
Quad-core 1.5 GHz CPU with 512 MB RAM
The quad-core processor and 512 MB of RAM support advanced features such as VPN Fusion, adaptive QoS, and traffic analysis running concurrently without requiring the user to disable other functions.

- EAN4711387534496
- Works as a standalone WiFi 7 wireless router in Wireless Router Mode.
- Compatible with ASUS AiMesh routers — can operate as a primary AiMesh router or as an AiMesh node.
- Supports legacy WiFi devices on both 2.4 GHz and 5 GHz bands alongside WiFi 7 clients.
- Can operate in Access Point Mode for networks where a separate router handles routing duties.
- The 1-pack covers a single unit; the claimed 6,500 sq. ft. coverage figure applies to the 3-pack configuration, not this single unit.
- Does not include a 6 GHz band — this is a dual-band (2.4 GHz + 5 GHz) device, not a tri-band or quad-band unit.
Best for
- Households upgrading to WiFi 7 who want MLO support for both current WiFi 7 devices and a fallback that still serves older 2.4/5 GHz clients.
- Users with a 2.5G internet connection who need a router with matching 2.5G WAN throughput rather than a standard gigabit port.
- Mesh network builders who already own ASUS AiMesh routers and want to add a WiFi 7 node or primary router without replacing their entire network.
- Privacy-conscious users who need built-in VPN server and client support across multiple protocols — WireGuard, OpenVPN, IPSec, L2TP and PPTP — without a separate appliance.
- Homes with thick walls where a wired 2.5G backhaul between mesh nodes can compensate for poor wireless penetration between floors or rooms.
Trade-offs
- Users wanting a 6 GHz band — this device is dual-band only; there is no 6 GHz radio for the additional spectrum that tri-band WiFi 7 routers provide.
- Very large homes relying on a single unit — the 6,500 sq. ft. coverage claim in the product record is tied to the 3-pack, not a single BD4.
- Enterprise or multi-tenant deployments — the feature set and operating modes described are designed for home and small-office environments.
- Buyers needing more than two wired ports — it provides only two 2.5G Ethernet ports total (WAN/LAN auto-detecting), with no additional LAN ports listed.
