Using IDE 1.8.5 webserver example, on Leonardo or Mega with Wiznet5100.
It wont render on Firefox / opera. Just get "This site can’t be reached"
However it will show on serial monitor that it gets a connection from the browsers as this shows just after I refresh browser
new client
GET / HTTP/1.1
Host: 192.168.0.120

client disconnected
I only did 2 changes to webserver example
byte mac[] = {
0xAA, 0xAA, 0xAA, 0xBA, 0xAA, 0x20
};
IPAddress ip(192, 168, 0, 120);
Arduino Ethernet shield is plugged directly into Asus RTN16.
Tried 3xLeonardos, 1xMega, 1xUno and 2xW5100, and 2 new ethernet cables.
mac address is unique to my network
Also tried from can't ping outside my network using ICMPPing from playground - Networking, Protocols, and Devices - Arduino Forum
byte mac[] = {
0xAA, 0xAA, 0xAA, 0xBA, 0xAA, 0x20
};
IPAddress ip(192, 168, 0, 120);
IPAddress gateway(192,168,0,2);
IPAddress subnet(255,255,255,0);
Ethernet.begin(mac, ip, gateway,gateway,subnet);
Any help appreciated
/*
Web Server
A simple web server that shows the value of the analog input pins.
using an Arduino Wiznet Ethernet shield.
Circuit:
* Ethernet shield attached to pins 10, 11, 12, 13
* Analog inputs attached to pins A0 through A5 (optional)
