     some time. It's completion is signalled by updateCompleted(). In the absence of a
     configuration update this function returns the best estimate at the time of the call.
+    Therefore, if WLAN configurations are of interest, it is recommended that
+    updateConfigurations() is called once after QNetworkConfigurationManager
+    instantiation (WLAN scans are too time consuming to perform in constructor).
+    After this the data is kept automatically up-to-date as the system reports
