wlanctl-ng and wep

Hi,
After much struggling (I am a newbie) I have almost got wlanctl-ng
installed on Suse 8.2 personal using a zoom air usb client. What
configuration files do I have to set up when I have got it all installed to
set the WEP key etc. Do I still create the files in /etc/sysconfig/network
or are they elsewhere. I can see it has detected the client mac address and
has connected to the ap, the mac address is right. I need to know what to do
next to get the connection configured with WEP and then get the routing etc
sorted. I thought I was close but now I seem a long way from getting it
sorted.

Many Thanks

Jon
