Arduino Ethernet Shield 2 not working - arduino

Question

I am currently trying to get the Ethernet Shield working on my Mega. I was trying to run the Webserver example but the program seems to stuck at one point, so I tried to start from scratch.
This is my test code:
#include <Ethernet.h>
#include <SPI.h>
byte mac[] = {
0x90, 0xA2, 0xDA, 0x0F, 0xF6, 0x3D
};
byte subnet[] = { 255,0,0,0 };
byte gateway[] = { 2,0,0,1 };
IPAddress ip(2, 0, 0, 1);
EthernetServer server(80);
void setup() {
Serial.begin(9600);
Ethernet.begin(mac, ip, gateway, subnet);
Serial.println("Ethernet started");
server.begin();
Serial.println("Server started");
}
void loop() {
// put your main code here, to run repeatedly:
Serial.println("Loop");
}
The output I get from the serial console is:
Etrted
Ethernet started
So I think the program gets stuck inside the EthernetServer::begin() function.
I am aware that there are earlier versions of ethernet shields which are not compatible to the mega, but the vendor of my shield says it is.
Also I don't understand, why it outputs the first line.
Thanks for your hints!

Answer 1

Arduino.cc and Arduino.org are not the same... Arduino.org, who is selling the ethernet shield 2, has their own IDE with the correct library! You can download it at http://www.arduino.org/downloads and the source can be found at https://github.com/arduino-org/Arduino/tree/1.7.4/libraries

Answer 2

Try this code form (http://www.arduino.cc/en/Tutorial/DhcpAddressPrinter):
#include <SPI.h>
#include <Ethernet.h>
// Enter a MAC address for your controller below.
// Newer Ethernet shields have a MAC address printed on a sticker on the shield
byte mac[] = {
0x00, 0xAA, 0xBB, 0xCC, 0xDE, 0x02 };
// Initialize the Ethernet client library
// with the IP address and port of the server
// that you want to connect to (port 80 is default for HTTP):
EthernetClient client;
void setup() {
// Open serial communications and wait for port to open:
Serial.begin(9600);
// this check is only needed on the Leonardo:
while (!Serial) {
; // wait for serial port to connect. Needed for Leonardo only
}
// start the Ethernet connection:
if (Ethernet.begin(mac) == 0) {
Serial.println("Failed to configure Ethernet using DHCP");
// no point in carrying on, so do nothing forevermore:
for(;;)
;
}
// print your local IP address:
Serial.print("My IP address: ");
for (byte thisByte = 0; thisByte < 4; thisByte++) {
// print the value of each byte of the IP address:
Serial.print(Ethernet.localIP()[thisByte], DEC);
Serial.print(".");
}
Serial.println();
}
void loop() {
}
And post what the serial monitor output is.

Try this:
NB. You can reuse your code written for Arduino Ethernet Shield, simply replacing
#include <Ethernet.h> --> #include <Ethernet2.h>
#include <EthernetUdp.h> --> #include <EthernetUdp2.h>
