and uploaded many different examples, but it does not work.
I tried direct connection to PC, connection with a home router, double checked the IP / DHCP parameters. Both don't recognize the device.
Is there a trick to make it work?
B
PS: I have tried many power supply units, so I don't think this is the problem. Moreover the orange and green LEDs of the Ethernet shield blink (but a little bit too randomly).
try to set pin 7 HIGH. it is connected to reset of the enc28j60 on the shield.
try the Ethernet library WebClient example. change the include to UIPEthernet and comment out the hardwareStatus() test
