ASUS ZenWiFi BD4 BE3600 Wireless Dual-Band 2.5G 2-Piece Mesh Wi-Fi System (White)

The ASUS ZENWIFI BD4 2PK is a two-node mesh Wi-Fi 7 system designed for homes and small offices that want faster wireless speeds and wider coverage without juggling multiple network names. Working together, the pair blankets up to 4900 square feet with a single SSID and delivers aggregate throughput up to 3.6 Gb/s across the 2.4 and 5 GHz bands, so every room can stream, game, or work online with confidence.

Each unit carries two 2.5-gigabit Ethernet ports that automatically detect whether they should act as WAN or LAN connections. You can link the nodes with a wired backhaul through these ports to lock in maximum stability, or leave them untethered for a clean, cable-free setup. Internal antennas that support 160 MHz channel width and 4K-QAM modulation push more data through the air, while MU-MIMO, beamforming, and multi-link operation keep multiple devices talking at full speed.

Inside, a quad-core 1.5 GHz processor with 512 MB of RAM and 128 MB of flash memory manages traffic without slowdowns. WPA3 encryption, Trend Micro AiProtection Pro, and built-in VPN options help protect every phone, laptop, camera, and console on the network. Parents can set schedules and filters in seconds through the ASUS Router app, and power users can prioritize gaming traffic or create a guest network just as easily.

Whether you are equipping a multi-level townhome, an open-concept office, or a brick-walled studio, the ZenWiFi BD4 provides strong, consistent coverage that adapts as your devices roam. Setup takes only a few taps on a smartphone, and future-proof Wi-Fi 7 features ensure the system is ready for the next generation of laptops, phones, and smart home gear.
