Hi Adrian, Just to make sure: | ifconfig wlan0 regdomain DE can't work. So I used: | ifconfig wlan0 down | ifconfig wlan0 ecm | ifconfig wlan0 regdomain ETSI | ifconfig wlan0 up | ifconfig wlan0 list channel But this also shows me not the channels 12/13. BTW ath vs. iwi: As you read in my first mail, I have the same issue if I use ndis for my device. If you can build a ndis driver for your interface (NDISulator), you should have the same issue.
