Dear sir,
How can I use this start kit access Ethernet network.
I plug this board in my network, it get dhcp 10.0.0.35
Then I try to lunch any network examples ,
I try to program IP and mac address fellow internet fail.
Try to use IP and mac address as eth0 failed
all failed.
Is this kits stop the Arduino Sketch network access?
Could you help to provide any example how to access the current ethernet in sketch is very helpful?
I try to use blynk but the dhcp example fail in connections, then I swap to arduino ethernet examples, all failed.

In the above ether interface which I can use Ethernet module to talk outside?
If you can provide some example is very appreciate
This is my example:
/*
Telnet client
This sketch connects to a a telnet server (google.com)
using an Arduino Wiznet Ethernet shield. You’ll need a telnet server
to test this with.
Processing’s ChatServer example (part of the network library) works well,
running on port 10002. It can be found as part of the examples
in the Processing application, available at
processing.org/

// Enter a MAC address and IP address for your controller below.

IPAddress ip(10, 0, 0, 35); // what we should put here, or the sketch network is total cannot work in this start kit??
// Enter the IP address of the server you’re connecting to:
IPAddress server(10,0,0,13);
// Initialize the Ethernet client library
// with the IP address and port of the server
// that you want to connect to (port 23 is default for telnet;
// if you’re using Processing’s ChatServer, use port 10002):
EthernetClient client;
void setup() {
// start the Ethernet connection:
Ethernet.begin(mac, ip);
// Open serial communications and wait for port to open:
Serial.begin(9600);
while (!Serial) {
; // wait for serial port to connect. Needed for native USB port only
}
// give the Ethernet shield a second to initialize:
delay(1000);
Serial.println(“connecting…”);
// if you get a connection, report back via serial:
if (client.connect(server, 23)) { // I had installed telnet server on 10.0.0.13.
Serial.println(“connected”);
} else {
// if you didn’t get a connection to the server:
Serial.println(“connection failed”);
}
}
void loop() {
// if there are incoming bytes available
// from the server, read them and print them:
if (client.available()) {
char c = client.read();
Serial.print©;
}
// as long as there are bytes in the serial queue,
// read them and send them out the socket if it’s open:
while (Serial.available() > 0) {
char inChar = Serial.read();
if (client.connected()) {
client.print(inChar);
}
}
// if the server’s disconnected, stop the client:
if (!client.connected()) {
Serial.println();
Serial.println(“disconnecting.”);
client.stop();
// do nothing:
while (true);
}
}
Thanks
