Ok - I don't usually talk to myself (not in public anyway) - but here 
are my findings.  When in 11b mode, everything works fine (I didn't try 
going to the edge of my coverage area though - too comfortable on my 
couch).  When in 11g mode, I see the rate flap up and down between 48M 
and 24M, and each time it switches, it loses some packets in between 
modes.   I just now manually set my client (FreeBSD of course) to 36M, 
and it seems to be holding up for now.  Here's all I did:

ifconfig ath0 media OFDM/36Mbps mode 11g

Give that a try on the FreeBSD AP, and see if that helps at all (you may 
want to try the 11b modes, like:
ifconfig ath0 media DS/2Mbps mode 11b
or something..
