wpa_supplicant and hidden ssid

[Katharina Brandl]

Hello Helmut,

thanks a lot for your help. ap_scan=1 doesn't work, but ap_scan=2 and 
pairwise/group ciphers in my config file it works fine.
So for others having the same problems, my wpa_supplicant.conf:

ctrl_interface=/var/run/wpa_supplicant
ctrl_interface_group=wheel
ap_scan=2

network={
ssid="mySSID"
key_mgmt=WPA-PSK
psk="passphrase"
priority=5
proto=WPA
pairwise=TKIP
pairwise=TKIP
}

What exactely is the meaning of proto and priority? Becauce these two 
line are the only ones I added and now I works...

Regards,
Kathi
