Yeah now it works with dhcpcd. Thanks a lot Roy!
After trying out several ideas I suspected that dhclient, pump and 
probably most other DHCP clients take down the interface as I noticed 
when making a WEP connection.
I really wonder why I havent't found anything about this issue neither 
in the mailinglist nor in the documentation. I think this should be 
mentioned somewhere as most 'regular' users use DHCP with their wlan 
routers and have no idea about the DHCP process.
