Create a file under your home directory or the root directory if you have installed knoppix named whatever you want.
chmod the file to 0776. In the file type the following.
Code:
wpa_supplicant -D ndiswrapper -i (your interface) -c /etc/wpa_supplicant.conf -ddKt
pump -i wlan0
Before you run this file make sure you have a file under /etc named wpa_supplicant.conf with the following information
Code:
ctrl_interface=/var/run/wpa_supplicant
eapol_version=1
ap_scan=1

network{
ssid="your network"
scan_ssid=1
psk="your key"
proto=WPA
key_mgmt=WPA-PSK
pairwise=TKIP or AES or whatever you use
group=same as pairwise
priority=1
}
This should work with kwifimanager
