    private void reportWifiOff(int reason) {
        Slog.d(TAG, "reportWifiOff, reason: " +
                (reason == DISABLE_WIFI_SETTING ? "wifi setting" : "airplane mode on"));
        Intent intent = new Intent(WifiManager.WIFI_OFF_NOTIFY);
        intent.putExtra(WifiManager.EXTRA_WIFI_OFF_REASON, reason);
