I purchased an Ethernet shield, and yesterday I got it. But I still have troubles getting it up and running...
I'll give as much details as possible.
Code: I use a slightly edited version of the 'WebClient' example:
#include <Ethernet.h>
byte mac[] = { 0xDE, 0xAD, 0xBE, 0xEF, 0xFE, 0xED }; // standard MAC
byte ip[] = { 192,168,1,172 }; // unused IP, I pinged it
byte server[] = { 192,168,1,100 }; // desktop, 192.168.1.100
byte gateway[] = { 192, 168, 1, 1 }; //router's IP
byte subnet[] = { 255, 255, 255, 0 }; //subnetmaskClient client(server, 80);
void setup()
{
pinMode(14, OUTPUT);
pinMode(15, OUTPUT);
Ethernet.begin(mac, ip, gateway, subnet);
Serial.begin(9600);delay(1000);
Serial.println("connecting...");
Serial.println(client.connect());
Serial.println(client.connected());
//Serial.printlnif (client.connect()) {
Serial.println("connected");
client.println("GET /search?q=arduino HTTP/1.0");
client.println();
digitalWrite(15, HIGH);
} else {
Serial.println("connection failed");
digitalWrite(16, HIGH);
}
}void loop()
{
if (client.available()) {
char c = client.read();
Serial.print(c);
}if (!client.connected()) {
Serial.println();
Serial.println("disconnecting.");
client.stop();
for( ; ; )
;
}
}
Router: the router we've got is a LinkSys WAG200G. It has four ethernet ports and WiFi.
(such a thing:
)

Port 1 is used by the desktop I'm currently working on,http://www.arduino.cc/yabbfiles/Templates/Forum/default/code.gif port 3 is sometimes used by my old laptop, and sometimes by the shield.
I can't get access to it, because my dad forget the username and password... I'm only planning to reset it if there's no other way.
Shield: ethernet shield from DFrobot (WIZnet5100 chip), comptible with the official ethernet library.
IP, subnet, gateway, ...: The IP of my desktop is 192.168.1.100, so I use 192.168.1.172 for my Arduino. As subnet I use 255.255.255.0, and as gateway 192.168.1.1.
Print of the ipconfig command (translated):
C: \ Documents and Settings \ HP_Eigenaar> ipconfig
Windows IP Configuration
Ethernet adapter Wireless Network Connection:
Connection Spec. DNS suffix:

Default Gateway. . . . . . . . . : 192.168.1.1Ethernet adapter LAN:

And on my laptop I get the same, except for the IP, of course, there it is 192.168.1.101.
I tried 'shared internet', by enabling it on my desktop and putting the jack from my Arduino to the jack named ethernet. My computer connects through WiFi (I heard that could cause the problem, is that true?). It didn't work... When I put it in a port of the router I can ping, it with my desktop, but now, I couldn't...
Any suggestions?
