Hello everyone,
I am new here but not at Arduino. My problem is that W5500 can't have an IP address.
I am getting this from serial port.
Chat server address:255.255.255.255
Here is my codes. It is example code
/*
Chat Server
A simple server that distributes any incoming messages to all
connected clients. To use telnet to your device's IP address and type.
You can see the client's input in the serial monitor as well.
Using an Arduino Wiznet Ethernet shield.
Circuit:
* Ethernet shield attached to pins 10, 11, 12, 13
* Analog inputs attached to pins A0 through A5 (optional)

// Enter a MAC address and IP address for your controller below.
// The IP address will be dependent on your local network.
// gateway and subnet are optional:
byte mac[] = {

};
IPAddress ip(192, 168, 1, 177);
IPAddress myDns(192, 168, 1, 1);
IPAddress gateway(192, 168, 1, 1);
IPAddress subnet(255, 255, 255, 0);
// telnet defaults to port 23
EthernetServer server(23);
boolean alreadyConnected = false; // whether or not the client was connected previously
void setup() {
// initialize the ethernet device
Ethernet.begin(mac, ip, myDns, gateway, subnet);
// start listening for clients
server.begin();
// Open serial communications and wait for port to open:
Serial.begin(9600);
Serial.print("Chat server address:");
Serial.println(Ethernet.localIP());
}
void loop() {
// wait for a new client:
EthernetClient client = server.available();
// when the client sends the first byte, say hello:
if (client) {
if (!alreadyConnected) {
// clead out the input buffer:
client.flush();
Serial.println("We have a new client");
client.println("Hello, client!");
alreadyConnected = true;
}
if (client.available() > 0) {
// read the bytes incoming from the client:
char thisChar = client.read();
// echo the bytes back to the client:
server.write(thisChar);
// echo the bytes to the server as well:
Serial.write(thisChar);
}
}
}
I do not know what to do. I've watched every video and read article. I have turned off my firewall also.
By the way w5500 is connected to home modem.
Here is the module that I use.
NOTE
I will sleep now. I am on this case for 4-5 hours.
Thanks.
