Yes, just send the IP to the serial monitor.
You can add DHCP to that EtherCard example, have a look at the DHCP example and modify your sketch.
You must use different mac addresses for everything,
With the same mac address, the router thinks it is the same client and gets confused.
Yeah I guessed as much conserning the router. I don't really need to use the DHCP-code I think since I need tp have the Arduinos to have a static IP, and a central router sets up te network so my guess is that it confirms the static IP of the Ethernet shield.
Problem I can't figure out: since the router connected to the Arduino is set up to be in client mode, and since it has an IP,is this going to be a problem? When I would send data to the Arduino, which IP do I send it to? The router or the Ethernet shield?
