WiFi Ping

/*

  This example connects to a encrypted WiFi network (WPA/WPA2).

  Then it prints the  MAC address of the board,

  the IP address obtained, and other network details.

  Then it continuously pings given host specified by IP Address or name.

  Circuit:

  * Board with NINA module (Arduino MKR WiFi 1010, MKR VIDOR 4000 and UNO WiFi Rev.2)
