/*

 This example connects to an WPA encrypted WiFi network.
 Then it prints the  MAC address of the Wifi shield,
 the IP address obtained, and other network details.
 It then polls for sketch updates over WiFi, sketches
 can be updated by selecting a network port from within
 the Arduino IDE: Tools -> Port -> Network Ports ...

 Circuit:
 * WiFi shield attached
 * SD shield attached
