@ present i have connected to switch . Where my server mentioned connected to modem.
I have similar set up as shown in image. But all device connected to switch 5 port.
From Model one LAN connection goto switch port 0
from PC one LAN cable connection goto switch port 1
from Ethernet cable goto switch port 2.
And all under same network.
Question are:
1) how to configure IP address for all, I have made test run for static ip address. connecting directly Ethernet shield and Ethernet port of PC . which is working fine
2) How to control LED in below example. Individually the code working fine.
3)How to keep option to change date and time here. Which can replicate in web server.
#include <SPI.h>
#include <Ethernet.h>

int led = 4;
byte mac[] = {
0xDE, 0xAD, 0xBE, 0xEF, 0xFE, 0xED };
