Thank you. Executing these commands did start wicd. Clicking on icon in wbar does not. This kind of resolves my problem as I can use commands intead of icon. However, I have a related question you might be kind to help with:
I was hoping wicd has possibility to specify authentication required to log in to WPA2, which means login consisting of identity and password. I cannot seem to find such preference in wicd, which means wicd does not give me more than just wifi tc.
