Comment (by Marek):
Well, seem this issue doesnt want to let go...
the setup worked for a week, then started to break again - i experience
disconnections at various intervals. I have set up an open access AP with
no daemon running:
{{{
iface ath0 inet static
pre-up wlanconfig ath0 create wlandev wifi0 wlanmode ap
post-down wlanconfig ath0 destroy
address 10.0.1.1
netmask 255.255.255.0
wireless-mode master
wireless-channel 7
wireless-essid myssid
}}}
yet, when i try to connect to this AP with wpa_supplicant from another
machine (both AP and client are using atheros/madwifi), i receive;
{{{
...
Wireless event: cmd=0x8b1a len=17
Wireless event: cmd=0x8b15 len=20

}}}
apparently it receives the new AP event with zeroed MAC (disconnection)
but this must come from the madwifi driver, as like i said there is no
daemon (like hostapd) running on the AP
i have tried various snapshots of madwifi-ng on the AP (including todays),
but with no luck.
any thoughts about how to find out the core of the problem? For the start,
how to find out if this is really AP sending disconnection event or
somehow the client genrates it on its own?
any help will be really aprreciated
