I have a Esp32 connected to Router with cable, how to connect internet ?
I would linke how to connect internet with shield W5500 Esp32 (cable) and after use library Firebase ?

There are threads about this topic already:

Basically you have to use a fixed version of the Ethernet library that works for the ESP32 (open issue). You can use my version of the library (GitHub - maxgerhardt/Ethernet: Ethernet Library for Arduino) with the provided examples and also OTA.

Firebase is available as a library (GitHub - mobizt/Firebase-ESP32: 🔥 Firebase RTDB Arduino Library for ESP32. The complete, fast, secured and reliable Firebase Arduino client library that supports CRUD (create, read, update, delete) and Stream operations.) but hardcoded to WiFi in a few places it seems. You can create a fork and replace WiFi.h with Ethernet.h functions.

I already used this library (GitHub - mobizt/Firebase-ESP32: 🔥 Firebase RTDB Arduino Library for ESP32. The complete, fast, secured and reliable Firebase Arduino client library that supports CRUD (create, read, update, delete) and Stream operations.) but I prefer this (GitHub - ArtronShop/IOXhop_FirebaseESP32: Get Set Push Stream value on Firebase via ESP32)

    pinMode(ledVermelho, OUTPUT);
    digitalWrite(ledVermelho, 1);
    pinMode(ledAzul, OUTPUT);
    digitalWrite(ledAzul, 1);
}



void loop() {
    runConnectLocal();
}



void connectWifi() {
    // connect to wifi.
    WiFi.begin(WIFI_SSID, WIFI_PASSWORD);
    Serial.print("connecting");
    while (WiFi.status() != WL_CONNECTED) {
        Serial.print(".");
        delay(500);
    }
    Serial.println();
    Serial.print("connected: ");
    Serial.println(WiFi.localIP());
    Firebase.begin(FIREBASE_HOST, FIREBASE_AUTH);
}



// Methods to initialize ethernet services
void initializeEthernet() {
    Ethernet.init(33);// CS pin 33
    Ethernet.begin(mac);// use DHCP

    // 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
        }

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

    Serial.print("IP: ");
    Serial.println(Ethernet.localIP());

    Udp.begin(localPort);

    // Begin Blynk services
    Blynk.begin(auth);

    // Initialize Firebase Services
   //  Firebase.begin(FIREBASE_HOST, FIREBASE_AUTH);
}



void runConnectLocal() {
    int packetSize = Udp.parsePacket();
    if (packetSize) {
        Serial.println("Passou conexão local " + packetSize);
        Serial.print("Received packet of size ");
        Serial.println(packetSize);
        Serial.print("From ");
        IPAddress remote = Udp.remoteIP();

              Serial.print(remote[i], DEC);
            if (i < 3) {
                Serial.print(".");

    Serial.println(Udp.remotePort());

    // read the packet into packetBufffer
    Udp.read(packetBuffer, UDP_TX_PACKET_MAX_SIZE);
    Serial.print("Contents: ");
    Serial.println(packetBuffer);

    // send a reply to the IP address and port that sent us the packet we received
    Udp.beginPacket(Udp.remoteIP(), Udp.remotePort());
    Udp.write(ReplyBuffer);
    Udp.endPacket();

void powerLed() {
     int ledStatus = Firebase.getInt("power");
     Serial.println(ledStatus);
     digitalWrite(ledVermelho, ledStatus);
     digitalWrite(ledAzul, ledStatus); 
}

So, I have this code that I use to connect with Firebase, when I use connection wi-fi method using firebase, its work perfeclty

But, when trying the same firebase library and connection with lan cable with W5500 shield, its no work

more a details, when I use app blynk using connection cabe, its work, if I try use firebase library, show the following message when debug:
