I didn't realize it was a four your old thread.
Didn't think he understoud the possibility to plug in a WiFi USB Device, full screen the Windows VM and head to the IT department.
BTW, I have something simmilar but completely different (is why I arrived to this thread); briding to WiFi adapters works perfectly unless the company is using WPA2 Enterprise (RADIUS services). I was thinking if there was any way around this (without using NAT).
