It's a known bug on MBP's.  For what it's worth, it happens to me on  
my MBP too and I curse it mightily whenever I forget and start a  
sniffer on the wireless interface by accident.

 From the wireshark lists:

Apple uses Snort internally, maybe I can lob a query in there and  
they'll leap into action.  (And maybe Steve Jobs will give me a  
personal call to thank me.  I can always dream....)

I've turned off promiscuous.  Same problem.  Gotta ditch Snort.

I have no idea :(. All I know is that passive sniffing and being  
connected at the same time just do not work.

Kismet and company switch channels in order to scan, which  
automatically drops you from whatever AP you were connected to on  
the (now) old channel.

Not sure why just firing up snort would drop AP. I suspect the  
driver sees the card is now in promiscuous mode and decides it  
needs to reset the card / AP association.

Kinda weird. I do wifi sniffing w/ snort and kismet all the time.  
Kismet drops AP as expected. Snort never does.
