Unfortunately, this is the case here too. On one link, approx. 3 km distance, 
I got no link with both sides FreeBSD, athstats reported rssi 6 when one side 
was changed to Linux with madwifi, and rssi 23 when both sides were Linux. I 
was forced to use Linux on all radio links due this. I would like to repeat 
this test indoor, but did not have time yet. This drives me crazy because I 
am forced to use system I don't like :(
