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() {


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

  Ethernet.begin(mac, ip);


void loop() {

the problem here is the Ethernet library that you import.

The reason is that the MDuino 21 uses the W5100 ethernet chip and the MDuino 21+ uses the W5500.

So you have to use the “Ethernet2.h”. To fix your following problems look out in this link, which test a Ethernet configuration on a MDuino Plus version.


Thanks for your trust!
