Arduino WiFi Sheild - Aduino lockup

Sometimes the connection will break on a wireless connection. This should prevent the lockup. Normally the lockup happens in the "while(client.connected())" loop and it becomes an endless loop. The loopCount variable controls the timeout. If you see a "Timeout" message on the serial monitor, the sketch would have locked up there.

      int loopCount = 0;

      while(client.connected()){  
         while(client.available()) {
             // read the bytes incoming from the client:
             char thisChar = client.read();
             // echo the bytes back to the client:
             client.write(thisChar);
             // echo the bytes to the server as well:
             Serial.write(thisChar);
              loopCount = 0;
         }         
         delay(1);
         loopCount++;

         if(loopCount > 10000) {
         {
             client.stop();
             Serial.println();
             Serial.println(F("Timeout"));
         }
      }
      client.stop();

edit: I changed server.write() to client.write. You want that sent to only that client.
