i have a Arduino Ethernet Shield V2 and am using the example Ethernet/chat server from arduino but can not get my router to see the arduino lights on shield are on or flashing I have put a free ip address in and gateway ,subnet address ….. ??????
Client test code you can try to check your setup.
//zoomkat 12-08-11
//simple client test
//for use with IDE 1.0
//open serial monitor and send an e to test
//for use with W5100 based ethernet shields
//note that the below bug fix may be required
// http://code.google.com/p/arduino/issues/detail?id=605
#include <SPI.h>
#include <Ethernet.h>
byte mac[] = { 0xDE, 0xAD, 0xBE, 0xEF, 0xFE, 0xED }; //physical mac address
byte ip[] = { 192, 168, 1, 102 }; // ip in lan assigned to arduino
//byte gateway[] = { 192, 168, 1, 1 }; // internet access via router
//byte subnet[] = { 255, 255, 255, 0 }; //subnet mask
byte myserver[] = { 208, 104, 2, 86 }; // zoomkat web page server IP address
EthernetClient client;

the code will not compile .....EthernetClient client; dose not name a type
the code will not compile .....EthernetClient client; dose not name a type
Better upgrade to 1.0. I'm expecting that you will have.
will try that now
If that doesn't help, you might want to post what operating system you are using. The Linux version of the IDE has a bug in the ethernet library.
still getting same with new softwear .... 'ethernet client' dose not have name type
ok just got rid of all old lidrary's and crap and reinstaled softwear ...run the code.. sent e came back with connection failed any one any ideas... i am on windows xp
