if ((config.state() & QNetworkConfiguration::Discovered) !=

}
QNetworkSession *networkSession = new QNetworkSession(config, &app);
networkSession->open();
networkSession->waitForOpened();
if (networkSession->isOpen()) {
// Save the used configuration
QNetworkConfiguration config = networkSession->configuration();
