hi guys.. iam experiencing a problem with my ethernetshield.. it seems like it cant connect to the network though the code and the router configuration is correct.. i've been using the sample sketch and upload it to the uno.. it uploads but nothing shows up in the browser when i type the Ip address... sometimes it works but sometimes it's not. can be the shield defective?
Which ethernet shield is it?
Which example? File->Examples->Ethernet->WebServer? What IP address? What is the address of your router?
