I were having the same problem in Mandrake linux, and reinstalled Mandrake. Could not find the error.But i found a way to make the wirelesscard work. here are the commands:
urpmi kernel-source gcc cvs
cvs -d
server:anonymous@cvs.sourceforge.net:/cvsroot/madwifi login
cd /usr/local/src
cvs -z3 -d
server:anonymous@cvs.sourceforge.net:/cvsroot/madwifi co -P madwifi
cd madwifi
make
sudo make install
cp -rf /lib/modules/"YOUR_KERNEL_VERSION"mdkcustom/net/* /lib/modules/"YOUR_KERNEL_VERSON"mdksmp/kernel/net/
cp /etc/modprobe.conf /etc/modprobe.conf_backup
echo "alias ath0 ath_pci" >>/eth/modprobe.conf
depmod -a
modprobe ath_pci
Afterwards these comands you can find and configure your card in Harddake..
