Sorry, I am new to this and have no idea where to post features requests.
I really hope that the next update for Knetwork Manager will allow it to remember wireless ppasswords without the need of Kwallet.
I think that there should be an option which allows users to choose if they want to enter password every time or not.
I wish Knetwork Manager could be like in Ubuntu Gnome, you enter WPA password once and from there on it connects automatically every time you log in in the future.
