Arduino WiFi shield working intermittently, "WiFi Shield not present" I am trying to use the official arduino wifi shield, It works occasionally, but most of the time (when running the WiFi web server example code, or my derivitave program, it outputs WiFi shield not present on the terminal. I have tried updating the firmware several times, but it has not fixed the problem. Is the wifi shield always this unreliable? What can I do to fix it?
Be sure the shield is not shorting out on the metal USB socket on the Arduino board. I don't know if this is still an issue but I've seen many Arduino boards with black electric tape on the top of the USB socket to insulate it from shorting out the shield.
