Which WiFi shield? Typically shields draw power all the time. If that is not what you want, you'll need a non-shield version or to connect the shield to a breadboard and re-wire the connections to the Arduino. The power to the shield as a shield can not be controlled by software. The power to the shield, on the breadboard, could be.

Hello,

I've the same issue and it's seems to be a well-known issue.
It seems there is an automatic process to reconnect the shield, so I tried to force the disconnection with this code:

actualTime=millis();
startTime= millis();
while(actualTime - startTime < 45000 ) {
WiFi.disconnect();
actualTime = millis();
}

With this code, the shield is disconnected but it is impossible to reconnect the shield after this disconnection
=> Afterward, the shield won't be recognized by the Arduino or the status returned by the function "begin" is = 4, and not WL_CONNECTED.

(Arduino Duemilanove for me)

Does anyone have any idea of how to solve this?
Thanks,
Romain.
