Hello, I'm new to the Arduinos and have problems getting the Ethernet SHield working. HW: Mega 2560, new Ethernetshield with W5100 (Connector left, reset button and regulator left, SD right, LEDs up right) As far as I understand, I only have to use eg. the FILE->Examples->ETHERNET->DhcpAdressPrinter.
When I do that, no connection to the Router, Power is on. Ethernetcable plug in: Link, 100M, Fulld light up. every some seconds LINK goes off while RX light on, TX stays off. So, looks like there is connection. But no message on the SERIAL Monitor, and not visible in the network (checked with nmap), No IP is given out.
Do I have to configure something? Any other idea but : give it back, you are to stupid?
Any help apprechiated, Ingo
