Revision history [back]

For the love of all that is good, please learn to indent your code!

There may be a problem with your setup function. you need to add a ; after the while(!Serial) line, this is meant to wait until the serial port is setup, but inside this loop you're writing to the Serial port if it's not setup which may be causing some problems.

while (!Serial);
Serial.println("Starting wifi");

I recommend printing some useful debugging information to the serial port and viewing it from your computer to see what's going on. If you can describe in more detail how this is failing then we'll be able to help you more.
