Subject: [OS2Wireless] Virtual Switch from Innotek Virtual PC can't see out through Prism mini-pci WiFi of Thinkpad A31

A follow-up to my last reply. At Warpstock this morning, I'm sitting 
next to Oliver Stein from Innotek, and just asked him about this issue. 
Here's a more exact answer:

In order for Vswitch to work with Wi-Fi, two things need to happen: The 
driver for the card must support promiscuous mode (Jens' drivers do, 
others may not); and the access point must be able to work 
inefficiently, meaning, it must not discard packets signed with a 
different MAC address than the Wi-Fi NIC of the client; many AP's - for 
the sake of efficiency and security - simply discard such packets.

Which AP are you using?
