TROUBLESHOOTING ARDUINO WIFI SHIELD (INTEGRATED ANTENNA)

Using Arduino Networking, Protocols, and Devices
1

Hey all,

I just bought the ARDUINO WIFI SHIELD with INTEGRATED ANTENNA. I have mounted it to an Arduino Uno R3. When I run the example ScanNetworks code I receive the prompt, 'WiFi shield not present.' I've also run the standard Blink example to make sure the shield is properly mounted and that works fine. The WIFI shield's L9 light blinks on code upload, but other than that I don't have much to go on in the way of trouble shooting.

Appreciate any help. Photos attached.

Remove the jumper from the pins next to the SD card slot. That jumper is for programming the wifi ICs with new firmware.

edit: Also remove that LED. I don't see a resistor and, unless it has one built in, that would prevent the SPI clock from working.
