I only noticed it because there were 2 lines with the same words
(1 mine, 1 yours) and I noticed the difference.

Sorry can't tell you ancient Chinese secret (sorry that's from a
commercial from the 1970's can't remember what they were selling :-)

See the script at the end of the message.

I think you'll need this for supplicant with WPA-PSK:

network={
   ssid="Third"_SSID
   psk="Third_WPA-PSK"
   key_mgmt=WPA-PSK
   proto=WPA
   priority=5
   bssid=AA:00:04:00:42:B0
}

The MAC address is not a real WAP (at least I don't think they
have a wireless router :-).

Off to the Wiki I go an voila: WPA-PSK = Wi-Fi Protected Access -
Pre-shared key. It's a little better (security wise) than the
WEP is.

Yipes! Not even WEP. I figure you'll work on that once you've fully
resolved the connectivity issue.

I don't know, I've never used kwifimanager.

Here's the script I install it in the /etc/init.d/network script just
before the end of the start (before the ;; for start).

# ====================================================================
# Load the ndiswrapper module and start the wpa_spplicant daemon
# ====================================================================

WLAN='wlan0'
ADDRESS='static'
# The IP address of this machine's wirless interface
IP='192.168.2.17'
# Default Gateway address
GATEWAY='192.168.2.254'

# This must match your WAP
SSID='YOUR_SSID_HERE'

# This must match your WAP
CHANNEL='6'

/sbin/modprobe ndiswrapper
if [ $? != 0 ]; then
     echo "Error loading ndiswrapper module"
     exit 1
fi

# SSID goes here
/sbin/iwconfig ${WLAN} essid ${SSID}
# channel number goes here, match your WAP settings
/sbin/iwconfig ${WLAN} channel ${CHANNEL}
/sbin/iwconfig ${WLAN} commit

# This is taken care of in the wpa_supplicant
# iwconfig ${WLAN} key s:key_goes_here
/sbin/ifconfig ${WLAN} up

if [ "${ADDRESS}" == "static" ]; then
   # Static IP address
   /sbin/ifconfig ${WLAN} ${IP}
   sleep 1
   /usr/local/sbin/wpa_supplicant -dd -Dndiswrapper \
     -i${WLAN} -c/etc/wpa_supplicant.conf -B
   sleep 2
   /sbin/route add default gw ${GATEWAY} ${WLAN}
else
   # Dynamic IP address, only use one of the other
   # untested!
   #dhclient ${WLAN}
   #pump -i ${WLAN}
fi
#echo Done
