wpa_supplicant does not start automatically

[Malte Gell]

Hello!

I changed (again...) to a Fritz! USBN N stick and use it with kernel 2.6.31 
and compat-wireless-2.6. Works fine now.

But, wpa_supplicant does not start automatically... with my old stick it 
started automatically, i now have to issue 

wpa_supplicant -i wlan2 -c /etc/wpa_supplicant.custom

(The stick is recognized as "wlan2", i dont know why, it's the only stick in 
the system).

In which config file should I put the wpa_supplicant command so that I do not 
need to call it manually?

One other thing, iwconfig shows now encryption:

wlan2     IEEE 802.11abg  ESSID:"humpelstilzchen"
          Mode:Managed  Frequency:2.417 GHz  Access Point: 00:1F:33:FC:52:1C
          Bit Rate=54 Mb/s   Tx-Power=20 dBm
          Retry  long limit:7   RTS thr:off   Fragment thr:off
          Encryption key:off
          Power Management:off
          Link Quality=70/70  Signal level=-33 dBm
          Rx invalid nwid:0  Rx invalid crypt:0  Rx invalid frag:0
          Tx excessive retries:0  Invalid misc:0   Missed beacon:0

strange, I enforce WPA2 and wpa_supplicant confirms this, just iwconfig is wrong 
here.....
