Hello Friends,

I have buy one Arduino Uno R4 Minima and DFROBOT Ethernet and PoE Shield for Arduino - W5500 Chipset (DFR0850) i tested with my code and few examples to test the ethernet connection but with no luck. Also tried with usb c power or dc jack power but not working. the rj45 green and yellow leds is off. This is one example code i test

#include <SPI.h>
#include <Ethernet.h>

void setup() {
  // You can use Ethernet.init(pin) to configure the CS pin
  //Ethernet.init(10);  // Most Arduino shields
  //Ethernet.init(5);   // MKR ETH Shield
  //Ethernet.init(0);   // Teensy 2.0
  //Ethernet.init(20);  // Teensy++ 2.0
  //Ethernet.init(15);  // ESP8266 with Adafruit FeatherWing Ethernet
  //Ethernet.init(33);  // ESP32 with Adafruit FeatherWing Ethernet

  Serial.begin(9600);
}

void loop() {
  auto link = Ethernet.linkStatus();
  Serial.print("Link status: ");
  switch (link) {
    case Unknown:
      Serial.println("Unknown");
      break;
    case LinkON:
      Serial.println("ON");
      break;
    case LinkOFF:
      Serial.println("OFF");
      break;
  }
  delay(1000);
}

The only think not tried is to Power over PoE.

Any other people have problem with this?
Any help o suggestion?

Thanks Bill

Aren't you supposed to uncomment one of those lines in setup?
