    Arduino Ethernet Shield Tutorial

    Just a thought, when you normally plug your Arduino board into your computer the usb cable supplies the power. Most ethernet does not support power over internet (POI), so unless you are also connecting to your PC using usb at the same time you will need to supply external power to your board.If you already provided external power ignore this comment.
