มีปัญหาเกี่ยวกับ ethernet shield

ใช้โค๊ตนี้

/*

 * Simple Web Client

 * Arduino 1.0 version

 */

#include <SPI.h>

#include <Ethernet.h>

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

byte ip[] = { 192, 168, 1, 177 };    // change to a valid address for your network

byte server[] = { 173,194,126,119  }; // www.google.co.th

EthernetClient client;

void setup()

{

  Serial.begin(9600);      // start the serial library:

  Ethernet.begin(mac,ip);

  delay(1000);             // give the ethernet hardware a second to initialize

  Serial.println("connecting...");

  if (client.connect(server, 80)) {

    Serial.println("connected");

    client.println("GET /search?q=arduino HTTP/1.0"); // the HTTP request

    client.println();

  } 

  else {

    Serial.println("connection failed");

  }

}

void loop()

{

  if (client.available()) {

    char c = client.read();

    Serial.print(c);  // echo all data received to the Serial Monitor

  }

  if (!client.connected()) {

    Serial.println();

    Serial.println("disconnecting.");

    client.stop();

    for(;;)

      ;

  }

}

แล้วมันขึ้นว่า

connecting...

connection failed

 

disconnecting.
