I had a hell of a time with the system-config-network utility after installing my ndiswrapper so I finally removed my wlan0 profile. Then in my /etc/rc.d/rc.local I added the following lines (edit according to your setting) rebooted and things worked. Good luck if this works for you please let me know. -Coffee
Code:
sbin/iwconfig wlan0 mode managed
sbin/iwconfig wlan0 essid "yourid"
sbin/iwconfig wlan0 channel 6
sbin/iwconfig wlan0 mode managed
sbin/iwconfig wlan0 key open xxxxxxxxxx
sbin/ifconfig wlan0 up
dhclient wlan0
