title: IsConnectedToNetwork for Windows8 WinRT Fails
body: <p>Anyone know a good way to see if the user is online/offline? When I use public static bool IsConnectedToNetwork(); and see if it's false/true it seems to always be true, even when I shut down my internet to test it...</p>
  
  <p>Am I missing something?</p>
  
  <pre><code>public static bool nets()
  {
      bool go = 
          System.Net.NetworkInformation.NetworkInterface.GetIsNetworkAvailable();
  
      if (go == false)
      {
          return false;  
      }
      return true;
  }
  </code></pre>
  
  <p>Now, in my start-up I run:</p>
  
  <pre><code>var ba = nets();
  
  if (ba == false)
  {
      txtHeader.Text = "err";
  }
  if (ba != false)
  {
      // Code
  }
  </code></pre>
  
  <p>I also tried:</p>
  
  <pre><code>    public static bool IsConnectedToNetwork();
  </code></pre>
