I'm using hostapd 0.5.2 compiled with madwifi-ng r1475, and I get the
following when I attempt ot that hostapd:
# hostapd -dddd /rw/etc/hostapd-ath0.conf
Configuration file: /rw/etc/hostapd-ath0.conf
madwifi_set_iface_flags: dev_up=0
Using interface ath0 with hwaddr 00:02:6f:20:fa:82 and ssid 'test-ath0'
SIOCGIWRANGE: WE(compiled)=19 WE(source)=13 enc_capa=0x0
Flushing old station entries
madwifi_sta_deauth: addr=ff:ff:ff:ff:ff:ff reason_code=3
ioctl[IEEE80211_IOCTL_SETMLME]: Invalid argument
Could not connect to kernel driver.
Deauthenticate all stations
madwifi_set_iface_flags: dev_up=0
I know I've got hostapd compiled against the madwifi drivers i'm
using, and it is installed corectly as far as i can tell.
my config file
interface=ath0
driver=madwifi

logger_syslog_level=2
logger_stdout=-1
