title: Reachability.h boolean variable connectionRequired--what does this mean in plain terms?
body: <p>What does the connectionRequired variable mean in the Reachability.h class that Apple wrote? In plain English?  </p>
  
  <pre><code>//WWAN may be available, but not active until a connection has been established.
  //WiFi may require a connection for VPN on Demand.
  - (BOOL) connectionRequired;
  </code></pre>
  
  <p>Does it mean:</p>
  
  <p>--you could connect, but you haven't connected?
  --you need a password
  --you need VPN</p>
  
  <p>When do I need to check to see if this variable is true?</p>
