yes, I am using dhclient to be able to get IP address from our DHCP
if I kill dhclient instances remaining from previous tests, it works
again. Thanks for a hint.
BTW - IMO there is no need to have wlan0 up when starting
wpa_supplicant, even there is no need to have drivers loaded into
kernel. I have only a definition in modules.conf:
alias wlan0 hostap_pci
options hostap_pci essid OURNETWORK iw_mode Managed
... and everything goes well.
