nm-applet icon will be visible when NetworkManager is running (and nm-applet 
is running, of course), even if interfaces are unmanaged. So check that the 
daemon is executed.

nm-applet icon also dissapears when notifcation area widget is removed. If it 
is the case, right click the panel -> "Add to Panel..." -> and add 
"Notification Area"
