Hi!

I use the stuff in a different way (mostly manually).

For example:

Step 1)

ifconfig wlan0 up

Wait a little and check:

ifconfig wlan0 list scan

If there's no SSID listed, wait until one comes up.

Step 2)
wpa_supplicant -d -d -i wlan0 -c /etc/wpa-psk.conf

with /etc/wpa-psk.conf:

-----------
ctrl_interface=/var/run/wpa_supplicant
ctrl_interface_group=wheel
# home network; allow all valid ciphers
network={
    ssid="correct-ssid"
    key_mgmt=WPA-PSK
    psk="correct-psk"
}

-----------

Step 3)
dhclient wlan0

Now one should be able to connect to the wlan.

First wpa_supp*, then dhclient. wpa* provides the crypto so that
dhclient gets the DHCP packets.

Well, that's a start.
