iwi problem with WEP

[Johannes Hofmann]

normally I use iwi(4) in combination with WPA and it works 
mostly fine. 
Now I'm forced to use WEP and can't get it working. ifconfig
looks ok, but dhclient does not. Setting the IP address
manually doesn't help either.
I think it has to do with WEP encryption. Does anyone use
iwi with WEP?
