title: android.net.wifi.STATE_CHANGE: not triggered on Wifi disconnect
body: <p>Is it normal to only have a broadcast intent with action <code>NETWORK_STATE_CHANGED_ACTION</code> (whose constant value is  <code>android.net.wifi.STATE_CHANGE</code>) when a Wifi connection is coming back up?   I.e. I don't get this intent when Wifi is being disconnected.</p>
  
  <p><strong>UPDATE:</strong> I am mostly interested to >= 2.2 Froyo</p>
