OK to use wicd-gtk, you need the daemon running and NetworkManager not. So try this as root in a terminal
now try running wicd-gtk.
I know, its not easy to get used to but it works. If you want you can remove NetworkManager and make wicd default just by doing this.
equo install wicd (if you don't have it installed yet)
equo remove networkmanager
rc-update add wicd
now wicd daemon will come on at boot up. you can just add wicd-gtk shortcut to ~/.kde4/Autostart/
and now it will come on when you login to KDE (if that is your DE)
