Frequently Asked Questions
Which ASUS ZenWiFi BD4 pack should I buy?
Choose the 1-Pack to use one router or extend an existing ASUS AiMesh network, the 2-Pack for a larger or double-storey home, and the 3-Pack for large homes or thick walls.
Can one BD4 work on its own?
Yes. A single BD4 works as a standalone Wi-Fi 7 router. Connect either 2.5G port to your fibre or LTE box to get online.
Do I need to set up each unit separately?
No. Set up one BD4 as your router with the ASUS Router app, then add the others as AiMesh nodes from the app.
Does the BD4 work with my existing ASUS router?
Yes, if your ASUS router supports AiMesh. Add the BD4 as an AiMesh node to extend your network under the same Wi-Fi name.
Can I use it with a non-ASUS router?
Yes, in Access Point mode. Connect it to your existing router with an Ethernet cable to add Wi-Fi 7. Mesh roaming (AiMesh) needs ASUS routers.
Will my older phones and laptops connect?
Yes. It is backwards compatible with Wi-Fi 6, 5 and 4 devices. Wi-Fi 7 speeds need a Wi-Fi 7 device.
Does it support wired backhaul?
Yes. Link BD4 units with Ethernet through the 2.5G ports for a fast, stable connection between nodes.
Does the BD4 have USB ports?
No. It has two 2.5G Ethernet ports and no USB ports.
