It may be that your ESP32 is too far away from your WiFi router. The board antenna is very small and you need to be really close to your router to connect. I use an external 8dbi antenna.

You should probably try the example sketch that lists the SSID’s of networks the board can see as well as signal strength. For my ESP32 it’s called WiFiScan. Actually it’s pretty small so I’ll post it here:

/*
* This sketch demonstrates how to scan WiFi networks.
* The API is almost the same as with the WiFi Shield library,
* the most obvious difference being the different file you need to include:
*/
#include “WiFi.h”

void setup()
{
Serial.begin(115200);

// Set WiFi to station mode and disconnect from an AP if it was previously connected
WiFi.mode(WIFI_STA);
WiFi.disconnect();
delay(100);

Serial.println(“Setup done”);
}

void loop()
{
Serial.println(“scan start”);

// WiFi.scanNetworks will return the number of networks found
int n = WiFi.scanNetworks();
Serial.println(“scan done”);
if (n == 0) {
Serial.println(“no networks found”);
} else {
Serial.print(n);
Serial.println(” networks found”);
for (int i = 0; i < n; ++i) {
// Print SSID and RSSI for each network found
Serial.print(i + 1);
Serial.print(“: “);
Serial.print(WiFi.SSID(i));
Serial.print(” (“);
Serial.print(WiFi.RSSI(i));
Serial.print(“)”);
Serial.println((WiFi.encryptionType(i) == WIFI_AUTH_OPEN)?” “:”*”);
delay(10);
}
}
Serial.println(“”);

// Wait a bit before scanning again
delay(5000);
}

Don’t know why but I can’t get it to format properly.

Thanks for answering, Steve.
Luis, in your Arduino IDE, you can simply go to File > Examples >WiFi > WiFiScan

Thank you very much Steve you are right my Esp32 was very far from my router that was the problem =)
 

Great!
I’m glad you’ve found out the problem.
I’ll mark this issue as resolved. If you need further help, you just need to open a new question in our forum.

Sara
