xfce - How to make the Network Manager applet work in the Status Notifier plugin?

On Xubuntu the *Status Notifier* plugin (pacakge name : xfce4-statusnotifier-plugin) works natively, it's the default plugin that manage the *Network Manager* applet, which means it is this plugin that displays the little Wi-Fi icon on the panel. On Debian XFCE however the default plugin for the *NM* applet is the *Notification Area*. I'm trying to install the *Status Notifier* plugin on Debian to replace the *Notification Area* but I can't make it work, the plugin doesn't display any item. The xfce4-statusnotifier-plugin documentation says : > **Known Issues** > Plugin Doesn't Show Any Items > > There is already a running service which works with status notifier > items. Most probably it's the indicator-application service which is > used by xfce4-indicator-plugin. Make sure this service is not running: > remove this indicator from xfce4-indicator-plugin and remove the > service from autostart. But I don't understand it. Plus I don't have the same scenario since I don't have the xfce4-indicator plugin installed. In my case I think the problem is the Notification Area.
