If you can see this, congratulations! Your Ethernet shield is working correctly! Finally, the
Arduino board will also display that the Ethernet shield has been disconnected from the
remote server:
disconnecting
If everything worked correctly, it means that your Ethernet shield is working correctly,
and it can connect without any problems to your local network and to the Web.
If something didn't work as expected, there are several things you can check. First, make
sure that all connections are correctly made, and that the Ethernet cable is correctly
plugged between the shield and your router.
If the DHCP fails at the beginning of the sketch and your shield can't get an IP address,
please check whether DHCP is activated without limitations on the MAC addresses in the
configuration panel of your router.
Finally, if the Arduino board can't connect to the remote server, first check whether the
server itself is working by entering the URL of the test page manually in your browser.
