I am not surprised at this... 

The reason these cards are listed as not being able to act as an AP is because 
they do not have the ability to do bridging internally.  So to get it to act 
_like_ an AP, one would need to handle the packets in the OS software. I.e. 
the OS or routing software etc. would have to decide what to do with the 
incomming frames as the card cannot do this.  Just turning the flag in the 
registry to on will not work because there is nothing in the card to actually 
do the work, even though everything else is correctly lablelled as such...

In other words, the reason that the card cannot see or send traffic when set 
as an AP is because the OS assumes the card is doing the work.... which it 
isn't...
