Configure WLAN without applet?

[Tassilo Horn <tassilo member fsf org>]

Hi all,

I've recently switched from traditional network setup (with
wpa_supplicant) to NetworkManager, and it seems to work pretty well.
Unfortunately, to set up encryption one's supposed to use one of these
three NM frontends:

      - Gnome NM applet
      - knetworkmanager
      - pyNetworkManager

I don't want to use the first two, cause I don't use Gnome nor KDE, so
I've installed the last one and the applet sits in my XFCE tray.  It
lists my local WLAN, but the functionality to set a PSK for it seems to
be broken.  (Also the webpage states that it is very buggy...)

So is it possible to configure that WLAN without any of those applets,
maybe with some dbus calls?

If not, are there other frontends (preferably cli) beside the three
above?

Bye,
Tassilo
