OK, those work in my tests.. Which kernel version are you using? Do you
have any patches in it? Which Linux wireless extensions version

hostapd was unable to use an ioctl to configure the kernel driver. Could
you please verify that the wireless extensions are working correctly
with wireless-tools? For example, run following commands and report any

iwpriv wlan0 hostapd 1
# (or if your iwpriv is too old: iwpriv wlan0 prism2_param 34 1)
# this is the same ioctl that failed with hostapd

iwpriv wlan0

iwconfig wlan0
