ESP8266's WiFi.status() returning 1

[felixbm]

I'm trying to connect my ESP8266 to my WiFi network and it returned status code of 1. Can someone please explain what does it mean and what is the solution? I've searched for a couple of hours already but nothing came out. Here's my code:

#include <ESP8266WiFi.h>
#include <WiFiClient.h>
#include <ESP8266WebServer.h>

// WiFi CREDENTIALS
const char *ssid = "Moe's Family";
const char *password = "Blessed Family";

void setup() {
  // put your setup code here, to run once:
  Serial.begin(115200);
  Serial.println();
  Serial.println("Connect to: ");
  Serial.println(ssid);
}

void loop() {
  delay(5000);
  WiFi.mode(WIFI_STA);
  Serial.println();
  Serial.println("Connect to: ");
  Serial.println(ssid);
  Serial.println(WiFi.status());
  Serial.println(WL_CONNECTED);
  if (WiFi.status() != WL_CONNECTED) {
    WiFi.begin(ssid, password);
    delay(15000);
  }
  if (WiFi.status() == WL_CONNECTED) {
    Serial.println("From ESP Connected!");
  }
  else {
    Serial.println("From ESP Not Connected!");
  }
}

and here's my ESP setting:

I'm still pretty newbie on Arduino, but any kind of help will be appreciated. Thanks in advance!

I'm not sure myself, but when I start over using the cleaner code:

#include <ESP8266WiFi.h>
#include <WiFiClient.h>
#include <ESP8266WebServer.h>

// WiFi CREDENTIALS
const char *ssid = "xxxx";
const char *password = "xxxx";

void setup() {
  Serial.begin(115200);
  WiFi.begin(ssid, password);
  Serial.println("");
  Serial.print("Connecting");
  while (WiFi.status() != WL_CONNECTED) {
    delay(500);
    Serial.print(".");
  }

  Serial.println("");
  Serial.print("Connected to ");
  Serial.println(ssid);
  Serial.print("IP address: ");
  Serial.println(WiFi.localIP());
}


void loop() {
  if (WiFi.status() == WL_CONNECTED) {
    Serial.println("From ESP Connected!");
  }
  delay(5000);
}

My gut is telling me that maybe WiFi.mode(WIFI_STA) is causing the error?

By the way, it worked already, thanks Juraj and cbalakus for the help!

Here is a more extensive WiFi callback that I use for WiFI troubleshooting. You'll have to edit it for your situation.

void WiFiEvent(WiFiEvent_t event)
{
   log_i( "[WiFi-event] event: %d\n", event );
  switch (event) {
        case SYSTEM_EVENT_WIFI_READY:
          log_i("WiFi interface ready");
          break;
        case SYSTEM_EVENT_SCAN_DONE:
          log_i("Completed scan for access points");
          break;
        case SYSTEM_EVENT_STA_START:
          log_i("WiFi client started");
          break;
        case SYSTEM_EVENT_STA_STOP:
          log_i("WiFi clients stopped");
          break;
    case SYSTEM_EVENT_STA_CONNECTED:
      log_i("Connected to access point");
      break;
    case SYSTEM_EVENT_STA_DISCONNECTED:
      log_i("Disconnected from WiFi access point");
      break;
        case SYSTEM_EVENT_STA_AUTHMODE_CHANGE:
          log_i("Authentication mode of access point has changed");
          break;
        case SYSTEM_EVENT_STA_GOT_IP:
          log_i ("Obtained IP address: %s",  WiFi.localIP() );
          break;
        case SYSTEM_EVENT_STA_LOST_IP:
          log_i("Lost IP address and IP address is reset to 0");
          //      vTaskDelay( 5000 );
          //      ESP.restart();
          break;
        case SYSTEM_EVENT_STA_WPS_ER_SUCCESS:
          log_i("WiFi Protected Setup (WPS): succeeded in enrollee mode");
          break;
        case SYSTEM_EVENT_STA_WPS_ER_FAILED:
          log_i("WiFi Protected Setup (WPS): failed in enrollee mode");
          //      ESP.restart();
          break;
        case SYSTEM_EVENT_STA_WPS_ER_TIMEOUT:
          log_i("WiFi Protected Setup (WPS): timeout in enrollee mode");
          break;
        case SYSTEM_EVENT_STA_WPS_ER_PIN:
          log_i("WiFi Protected Setup (WPS): pin code in enrollee mode");
          break;
        case SYSTEM_EVENT_AP_START:
          log_i("WiFi access point started");
          break;
        case SYSTEM_EVENT_AP_STOP:
          log_i("WiFi access point  stopped");
          //      WiFi.mode( WIFI_OFF);
          //      esp_sleep_enable_timer_wakeup( 1000000 * 2 ); // 1 second times how many seconds wanted
          //      esp_deep_sleep_start();
          break;
        case SYSTEM_EVENT_AP_STACONNECTED:
          log_i("Client connected");
          break;
    case SYSTEM_EVENT_AP_STADISCONNECTED:
      log_i("WiFi client disconnected");
          break;
        case SYSTEM_EVENT_AP_STAIPASSIGNED:
          log_i("Assigned IP address to client");
          break;
        case SYSTEM_EVENT_AP_PROBEREQRECVED:
          log_i("Received probe request");
          break;
        case SYSTEM_EVENT_GOT_IP6:
          log_i("IPv6 is preferred");
          break;
        case SYSTEM_EVENT_ETH_GOT_IP:
          log_i("Obtained IP address");
          break;
    default: break;
  }
}

Thanks @Idahowalker, will try it later!
