I was trying to connect to wi-fi with lubuntu but I could not, I don't know exactly what is the problem, I used nm-applet and that was the result:
nm-applet
** (nm-applet:13926): WARNING **: Error retrieving accessibility bus address: org.freedesktop.DBus.Error.ServiceUnknown: The name org.a11y.Bus was not provided by any .service files
(nm-applet:13926): nm-applet-WARNING **: Failed to register as an agent: (32) An agent with this ID is already registered for this user.
nm-applet-Message: using fallback from indicator to GtkStatusIcon
UPDATE:
So I re-install it and tried again, the result as following:
