FEZ Spider Cannot recieved Ping packages

Hi. I’m trying to test if i can communicate to FEZ spider. its running a display code to show the IP if network is up. It shows the ip but when try ping it, it says destination host unreachable. i tried pinging it from router and same issue. A network administrator tried and says that the device isn’t responding to a ® response, and not coming up in an arp table. Any help . im not too technical so simple answers please.

PING may not be a valid test.

Where did you get the code to set up the network ? https://www.ghielectronics.com/docs/30/networking is the main source I’d recommend.
