Thank you, Chris. You are right. Having removed nm-applet and nm-system-settings (network plasma-widget was already removed), I installed knetwork manager. Now, I am online. No need for any gnome install. I don't use bluetooth, but plug the Huawei e220 into the usb. After a minut or two, it turns automagically up in the networkmanager-applet.
