WiFi can't connect on 2017.6 basic core (works on Fire)

[anichang]

Very minimal sketch:

void setup() {
  M5.begin(true,true,true,true);
  M5.Power.begin();
  WiFi.begin(ssid, password);
  M5.Lcd.println("TODO");
  delay(500);
}

void loop() {
  M5.update();
  delay(1000);
}

Doesn't work on my old Core:

It works on Fire:

Any clue?

Hello,
Could you please include the imports at the beginning of the code? did you import the proper library?
it seems that it says the SDCard failed, could you run the factory test image on your old core to see if you get any issues?
