Any ideas? If I understand correctly, it doesn't sound like something to do with the driver which is all I can control. I'd suggest sniffing the 802.11 frames to see if you can identify anything. If you have another system+card you can do this with something like: tcpdump -i ath0 -y IEEE802_11 or use your favorite tool. Sam
