Reply To: ASUS ZenWiFi BT8 Whole Home Tri-Band Mesh WiFi 7 System – Official Thread I have just upgraded my ASUS AiMesh system from 3 x ET12 (with one ET12 as the main router) and 7 x XD4 to 6 x BT8 (with one BT8…

I would not reset main BT8 router or any others as those extra 9 hidden SSIDs you’re seeing—3 per band (2.4GHz, 5GHz, 6GHz)—are probable internal backhaul and management SSIDs and important.

Even on wired backhaul, ASUS currently does not disable or allow to be disabled these wireless interfaces by default.

These SSIDs cannot be controlled individually via the Web UI. However, some can be hidden using NVRAM tweaks — via SSH, by editing the configuration of virtual interfaces (BSS), but this is only temporary and will not survive a reboot.

Interface Naming Breakdown Examples

– wl2

This refers to the main physical interface of the third wireless radio, which in your case (with tri-band routers like the ET12 and BT8) is usually the:

• 6 GHz band

 

– wl2.0

This is the primary SSID (BSS0) on that radio — the one you configured in the GUI.

• This is your main 6GHz SSID visible to users.

 

– wl2.1, wl2.2, etc.

These are virtual SSIDs (VAPs/BSSes) associated with the same physical radio. ASUS uses them for:

• Hidden backhaul SSIDs
• Management/control communication between AiMesh nodes
• WPA3 transition management frames
• Diagnostics or ASUS-specific functions
