    I had some difficult making Madwifi on Fedora Core 3 using WPA-PSK, but I
    succeed in the end. This what I did:

    Hardware: D-link wireless router DI-624 and miniPCI DWL-G650 on my notebook
    (also successful using a USB DWL-G122)

    Useful web pages:
    FAQ > http://www.mattfoster.clara.co.uk/madwifi-9.htm
    FC3 setup > http://fedoranews.org/blog/?p=599

    I got it working first with USB DWL-G122 using ndiswrapper and
    wpa_supplicant. So I knew I was doing it right with the router and that
    wpa_supplicant was working right. I didn't like this solution because on
    needs to run a custom kernel to increase stack size to 16k. ifup/ifdown wlan0
    worked no problem and therefore neat also.

    This was not true for the Madwifi module as described at the end of
    http://fedoranews.org/blog/?p=599. After lots of searching what worked for me
    was the following script:

    #!/bin/bash
    PATH=/sbin:/bin:/usr/bin:/usr/sbin/
    #Secure:
    #WPA-PSK Works!
    modprobe ath_pci
    ifconfig ath0 up
    #iwlist ath0 scan
    wpa_supplicant -Bw -iath0 -c/etc/wpa_supplicant.conf -Dmadwifi
    dhclient
    iwconfig ath0 rate 54M
    #iwconfig
    #ifconfig
    #NOTE: if you use ifup WPA-PSK doesn't work for this driver!
    #Also you might need to unplug it to get it to load ath0 properly

    I don't understand why ifup doesn't work, and therefore neat, like on the
    other wireless card but the above script works for me.

    To take the wireless connection down I have the following script:
    #!/bin/bash
    PATH=/sbin:/bin:/usr/bin
    #Shutting Down:
    ifdown ath0
    modprobe -r ath_pci
    killall -s SIGUSR1 wpa_supplicant
    killall -s SIGUSR1 dhclient

    Some of the code might be redundant.
