Ethernet Shield does not supplying the correct IP

Good Day Everyone.

I am having a hard time configuring the ethernet shield.

  1. I mounted the ENC28J60 Ethernet Shield on the Arduino Mega 2560.
  2. I connected the USB port of the Arduino to the USB port of my PC,
  3. I connected the ethernet port of the Ethernet Shield to a LAN Port of a TP-Link Router with an IP Address of 192.168.0.1 and has a DHCP starting address from .100 to .200

I put uploaded the code that I get from to the Arduino Module: https://www.arduino.cc/en/Reference/EthernetClient

#include <Ethernet.h>
#include <SPI.h>


byte mac[] = { 0xDE, 0xAD, 0xBE, 0xEF, 0xFE, 0xED };
byte ip[] = { 192, 168, 0, 100 };
byte server[] = { 64, 233, 187, 99 }; // Google

EthernetClient client;

void setup()
{
  Ethernet.begin(mac, ip);
  Serial.begin(9600);

  delay(1000);

  Serial.println("connecting...");

  if (client.connect(server, 80)) {
    Serial.println("connected");
    client.println("GET /search?q=arduino HTTP/1.0");
    client.println();
  } else {
    Serial.println("connection failed");
  }
}

void loop()
{
  if (client.available()) {
    char c = client.read();
    Serial.print(c);
  }

  if (!client.connected()) {
    Serial.println();
    Serial.println("disconnecting.");
    client.stop();
    for(;;)
      ;
  }
}

And then, from the serial window of Arduino IDE, I am getting

connecting... connection failed disconnecting...

I also tried some similar codes from above, some are outputting the shields IP, but still, I get the same problem, the Ethernet Shield does not output an IP Address or says "connected".

I also tried both straight-through and cross-over cables.

Please Help.

Thanks.

In your code:
byte mac[] = { 0xDE, 0xAD, 0xBE, 0xEF, 0xFE, 0xED };

Must match your Ethernet Shield mac address.

Maybe try letting your router provide an IP address via DHCP. To do that, just change the line in your setup routine to Ethernet.begin(mac);
