ENC28j60 Ethernet controller as web client

Projects Programming

Hi !

This hardware configuration is working as web server perfectly.

I am trying to use ENC28j60 Ethernet controller as web client.
I have got the folowing error:
I try to run a code web client but I can not get the ip of server.
What can be the problem ? Does anyone has this problem ? It is the dns server ? It can not translate the name ot ip. Here is the code.

// This demo does web requests to a fixed IP address, using a fixed gateway.

#include <EtherCard.h>

#define REQUEST_RATE 5000 // milliseconds

// ethernet interface mac address
static byte mymac[] = { 0x74,0x69,0x69,0x2D,0x30,0x33 };
static byte myip[] = { 192,168,0,190 };
static byte gwip[] = { 192,168,0,1 };
static byte hisip[] = { 216,58,209,206 };//


const char website[] PROGMEM 	= "www.google.com";
byte Ethernet::buffer[300];
static long timer;



void setup () {

  Serial.begin(57600);
  Serial.println("\n[getStaticIP]");
  
  if (ether.begin(sizeof Ethernet::buffer, mymac, 10) == 0) 
    Serial.println( "Failed to access Ethernet controller");

  ether.staticSetup(myip, gwip);
	
	
	if(ether.dnsLookup (website, false)){
		Serial.println( "dnsLookup ok");
	}else{
		Serial.println( "dnsLookup faild");
	}


  while (ether.clientWaitingGw())
    ether.packetLoop(ether.packetReceive());
  Serial.println("Gateway found");
	
	ether.printIp("My IP: ", ether.myip);
	ether.printIp("Netmask: ", ether.netmask);
	ether.printIp("GW IP: ", ether.gwip);
	ether.printIp("DNS IP: ", ether.dnsip);
	ether.printIp("SRV: ", ether.hisip);
  
  timer = - REQUEST_RATE; // start timing out right away
}

void loop () {
  ether.packetLoop(ether.packetReceive());
  
  if (millis() > timer + REQUEST_RATE) {
    timer = millis();
    Serial.println("\n>>> REQ");
    //ether.browseUrl(PSTR("/"), "bar", website, my_result_cb);
		ether.browseUrl(PSTR("/index.html"), "", website, my_result_cb);
  }
}

// called when the client request is complete
static void my_result_cb (byte status, word off, word len) {
  Serial.print("<<< reply ");
  Serial.print(millis() - timer);
  Serial.println(" ms");
  Serial.println((const char*) Ethernet::buffer + off);
}

The serial log is :

--> dnsLookup
DNS Lookup failed

My IP: 192.168.0.190
Netmask: 0.0.0.0
GW IP: 192.168.0.1
DNS IP: 8.8.8.8
SRV: 0.0.0.0

The serial log is :

--> dnsLookup
DNS Lookup failed

That's a bit hard to believe, given this code:

		Serial.println( "dnsLookup faild");
