zoomkat:
Simple server code you can try.
//zoomkat 12-18-10
//routerbot code
//for use with IDE 0021
//open serial monitor to see what the arduino receives
//use the \ slash to escape the " in the html
//address will look like http://192.168.1.102:84/ when submited
//for use with W5100 based ethernet shields

0xDE, 0xAD, 0xBE, 0xEF, 0xFE, 0xED }; //physical mac address

byte gateway[] = { 192, 168, 1, 1 }; // internet access via router

Thanks for this zoomkat, alas still no ping. I do get the serial output 'servertest1' but no LED or ping. I have noticed that although the LEDs on the RJ45 socket the link light is on but no activity from the activity LED. I really think that this board is not going to live.
