Hi,

we have same problems with Mduino 21+ and LAN, we can not set the IP address.

With this code we can ping Mduino 21 but we can not ping Mduino 21+:

#include <Ethernet.h>

#include <SPI.h>

byte mac[] = {0xDE, 0xAD, 0xBE, 0xEF, 0xFE, 0xED};

IPAddress ip(192, 168, 100, 10);

void setup() {

  Serial.begin(9600);

  while (!Serial); // wait for serial port to connect. Needed for native USB port only

  Ethernet.begin(mac, ip);

}

void loop() {

}
