ASUS BD4 Dual-Band WiFi 7 Mesh System

Create a two-node WiFi 7 mesh network for larger homes, connected-device environments, and sites where one router cannot provide consistent coverage throughout the space. The ASUS ZENWIFI BD4 2PK supports up to 3,600 Mbps total dual-band throughput across 2.4 GHz and 5 GHz wireless bands, with Multi-Link Operation support. Its two nodes operate under one network name, allowing client devices to move between coverage areas without manually changing SSIDs. Each node has two auto-sensing 2.5 GbE RJ45 WAN/LAN ports. Connect one port to a broadband modem when configuring a node as the router, or assign the ports to wired endpoints such as desktop systems, smart TVs, gaming consoles, and network storage. The same ports support Ethernet backhaul between nodes, keeping mesh traffic on a wired link where construction materials or wireless congestion would otherwise affect inter-node communication. The BD4 can operate as a wireless router, mesh node, or access point. ASUS Router app support provides mobile configuration from Android or iOS, while guest networking and parental controls separate visitor and household access. AiProtection Pro security, WPA3 support, and Smart Home Master SSIDs add network segmentation options for IoT devices and other connected equipment. This two-piece configuration is specified for coverage areas up to 4,900 square feet.
