Good Morning,
is there someone that can help me with this ? I've the connection that stop to work after a fews times

Code: [Select]

/*
  WiFi Web Server

 A simple web server that shows the value of the analog input pins.
 using a WiFi shield.

 This example is written for a network using WPA encryption. For
 WEP or WPA, change the WiFi.begin() call accordingly.

 Circuit:
 * WiFi shield attached
 * Analog inputs attached to pins A0 through A5 (optional)
