Web ICMP Ping
3+
4+
This sketch pings a device based on the IP address or the hostname
5+
using the WiFi module. By default the attempt is performed 5 times, but can
6+
be changed to max. 255
7+
8+
It requires the latest USB Wifi bridge firmware level and WiFiS3 library.
9+
10+
This example is written for a network using WPA encryption. For
11+
WEP or WPA, change the WiFi.begin() call accordingly.
