Same problem here.  See the thread " ath(4) packet loss problem" on  
current-users starting July 11th.

The problem appears more pronounced in low traffic situations. A  
single ping process active on the link (ie. no traffic other then   
the ICMP echo requests and replies) will see heavy packet loss and  
the device timeout.  As soon as you start other network traffic, the  
packet loss goes down.
