    public void test3GToWifiNotification() {

        // To avoid UNKNOWN state when device boots up

        cmActivity.enableWifi();

        } catch (Exception e) {

            Log.v(LOG_TAG, "exception: " + e.toString());

        }

        cmActivity.disableWifi();

        // As Wifi stays in DISCONNECTED, the connectivity manager will not broadcast

        // any network connectivity event for Wifi

        NetworkInfo networkInfo = cmActivity.mCM.getNetworkInfo(ConnectivityManager.TYPE_MOBILE);
