Recently I've bought an Arduino Mega 2560 R3 and a Shield Model Wireless SD R3 from http://www.amazon.de/Arduino-A000065-Netzwerkkarte-Wireless-SD-Shield/dp/B00L1FO860. I try to run the example from https://www.arduino.cc/en/Tutorial/ConnectWithWPA
Before running the sketch I turn the DIP switch to the position USB. It seems like the WIfi Shield is correct connected to the Arduino since the LEDs TX and RX are blinking during upload the Sketch.
Sadly as output I got only: WiFi shield not present
Currently I'm not sure if the hardware itself provide Wifi functionality. Does somebody know if it should work with this hardware?
