Here is my code. (I've left out the loop, obviously):

// Initialize the Ethernet server library
// with the IP address and port you want to use
// (port 80 is default for HTTP):
EthernetServer server(80);

void setup()
{
  // You can use Ethernet.init(pin) to configure the CS pin
  Ethernet.init(10);  // Most Arduino shields

  // 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
  }
  Serial.println("Ethernet WebServer Example");

  // start the Ethernet connection and the server:

Incorrect IP address when using Ethernet library with Arduino Uno and WizNet 5500 ethernet module

I'm trying to get an ethernet module with the W5500 chipset to connect to my network on an Arduino Uno, but whatever I do, I always get an incorrect IP address.

The module is connected as default SPI, with the CS pin on pin 10.

Initially I was using the wrong libraries (those meant for the ENC28J60), until Juraj pointed out to me that I had the W5500 chipset.

So I loaded the Ethernet WebServer example sketch in my Arduino IDE (1.8.13), changed the IP value, compiled it, and tried to run it. In my code, I set the IP to 192.168.123.225, but the serial monitor showed me IP 192.80.239.132 .

After some Googling I found a post called Ethernet library not initializing IP correctly, as well as several other pages each stating that the Ethernet2 library should be used for the W5500 chipset instead of Ethernet.

I've tried installing the Ethernet2 library from within the Arduino IDE, with the exact same result. I loaded the example sketch of this library, same result. After downloading the library from GitHub (as found on another page describing the same problem), I got some errors and commented out some sections as seen in my code below, but still with the same result.

In the commented code you can also see that I've added a check to see whether my module is actually recognized as a W5500, and it is...

So my question, while elaborate, is very simple: how can I set the IP correctly on a W5500 chipset module connected to an Arduino Uno?

Here is my code (I've left out the loop, obviously):

#include <SPI.h>
#include <Ethernet2.h>

// Enter a MAC address and IP address for your controller below.
// The IP address will be dependent on your local network:
byte mac[] = { 0xDE, 0xAD, 0xBE, 0xEF, 0xFE, 0xED };
IPAddress ip(192, 168, 123, 225);

// Initialize the Ethernet server library
// with the IP address and port you want to use
// (port 80 is default for HTTP):
EthernetServer server(80);

void setup()
{
  // You can use Ethernet.init(pin) to configure the CS pin
  Ethernet.init(10);  // Most Arduino shields

  // 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
  }
  Serial.println("Ethernet WebServer Example");

  // start the Ethernet connection and the server:
  Ethernet.begin(mac, ip);

  // Check for Ethernet hardware present
  /*
  if (Ethernet.hardwareStatus() == EthernetNoHardware)
  {
    Serial.println("Ethernet shield was not found.  Sorry, can't run without hardware. :(");
    while (true)
    {
      delay(1); // do nothing, no point running without Ethernet hardware
    }
  }
  else
  {
    if (Ethernet.hardwareStatus() == EthernetW5500)
    {
      Serial.println("Ethernet shield is a W5500");
    }    
  }

  if (Ethernet.linkStatus() == LinkOFF)
  {
    Serial.println("Ethernet cable is not connected.");
  }
  */

  // start the server
  server.begin();
  Serial.print("server is at ");
  Serial.println(Ethernet.localIP());
}
