I'm using ath5k and AR2413. With the option -D nl80211 the error message
disappeared, but I got another error:
After association, I always got a "Wireless event: new AP:
00:00:00:00:00:00", and then I got EVENT_DISASSOC because of the driver
event handler. Is this the root cause of the failure?
Just before that I got the following messages:
RTM_NEWLINK: operstate=0 ifi_flags=0x11003 ([UP][LOWER_UP])
RTM_NEWLINK: IFLA_IFNAME: Interface 'wlan0' added
RTM_NEWLINK: operstate=0 ifi_flags=0x1003 ([UP][LOWER_UP])
RTM_NEWLINK: IFLA_IFNAME: Interface 'wlan0' added
When I use madwifi with Honma's patch, I get only the first two lines.
 RTM_NEWLINK: operstate=0 ifi_flags=0x11003 ([UP][LOWER_UP])
RTM_NEWLINK: IFLA_IFNAME: Interface 'wlan0' added
