Jouni,

Thanks very much for your response.

I have since resolved the problem. For the record: it seems that I was 
over-configuring the wireless interface on the client prior to calling 
wpa_supplicant. What works is the following:

modprobe ath_pci
ifconfig ath0 up
wpa_supplicant -Bw -c /etc/wpa_supplicant.conf -iath0 -Dmadwifi
dhcpcd -d ath0

What does not work is setting a bunch of parameters (such as ssid, 
network mode, etc.) using iwconfig and iwpriv prior to calling 
wpa_supplicant.

My problem may have been due to one parameter being set in particular, 
but I haven't bothered trying to find out.

Best regards, Jan
