   . test3GToWifiNotification: test enabling Wifi without associating with any access point, Wifi stays disconnected, device should still connect to cellular.
   . testConnectToWifi: when switching from cellular to Wfi and associated with a given AP, connectivity manager broadcast the right informtion for mobile and Wifi.
