[No passthrough with SteamVR???]

I have the same problem.. the name of the lens is literally XR not VR.. 

[wifi mac address not available]

The headset's system software was the lastest and still those addresses were not available so I just reset the headset and I could see the wifi mac address and IP address. 

[wifi mac address not available]

is there reason why the wifi mac address of XR elite device is not available? 

only the bluetooth address is available.  

settings >  general > infromation > headset status > IP address and Wifi Mac address not available.
