Hmm - I wonder if you are losing packets when the device thinks the 
signal is weak, and it attempts to lower the connection speed to 
increase reliability.  Maybe try forcing it down to a low speed (like 
1mb/s or something?) and seeing if it continues to happen..

Maybe also try setting:
sysctl hw.ath.debug=1
and watch your dmesg/messages for hints..
