Can't connect to wireless using plasmoid-networkmanagement

Hi all,
after successfully installed plasmoid-networkmanagement I cannot connect to wireless (cable connection works fine).

I have OpenSuse 11.1 with kernel 2.6.27.48-0.3-default; KDE 4.5.2 and


02:06.0 Network controller: Intel Corporation PRO/Wireless LAN 2100 3B Mini PCI Adapter (rev 04) 

The plasmoid shows an essid but somehow nothing happens when I click it. I removed the essid from the Network Connection (KDE Control Module) and added it again, but nothing happened.

Bellow is the result from qdbus org.kde.kded /kded loadedModules

iamlost@nowhere:~> qdbus org.kde.kded /kded loadedModules
networkstatus
remotedirnotify
phononserver

As you can see networkmanagement is loaded but somehow the plasmoid not.

I appreciate any hints/ infos from you guys.
Thanks in advance,
T
