title: QNetworkConfigurationManager::allConfigurations() doesn't list WLAN
body: <p>Running under Windows 10, tested with two different Systems:</p>
  <p>When i run <code>QNetworkConfigurationManager::allConfigurations()</code> I don't get any WLAN configuration, even if I'm connected actively to a <strong>Wifi</strong> Network.</p>
  <p>Header:</p>
  <pre><code>public:
    NetworkManager(QObject* parent = 0);
  
  private slots:
    void onNetworkConfigUpdate();
  
  private:
    QNetworkConfiguration cfg;
    QList&lt;QNetworkConfiguration&gt; netcfgList;
    QNetworkConfigurationManager ncm;
  </code></pre>
  <p>.cpp</p>
  <pre><code>NetworkManager::NetworkManager(QObject* parent) : QObject(parent) {
      ncm.updateConfigurations();
      connect(&amp;ncm, SIGNAL(updateCompleted()), this,  SLOT(onNetworkConfigUpdate()));
  }
  
  void NetworkManager::onNetworkConfigUpdate() {
  netcfgList = ncm.allConfigurations();
  for (auto&amp; x : netcfgList) {
      if (x.bearerType() == QNetworkConfiguration::BearerWLAN) {
          qDebug() &lt;&lt; &quot;Wifi found: &quot; &lt;&lt; x.name();
      } else {
          qDebug() &lt;&lt; &quot;Something else: &quot; &lt;&lt; x.bearerType() &lt;&lt; &quot; - name: &quot; &lt;&lt; x.name();
      }
    }
  }
  </code></pre>
  <p>Output:</p>

  <p>I'm running on Windows 10; Qt 5.9.4 with MSVC2015</p>
  <p>I checked with an Intel Wireless Card and an external USB Wifi-Stick. Why is it not showing any WLAN?</p>
