  Hello everybody.

  Faced the problem of reconnecting to the WiFi network through the wifi.on (‘connected’) event.
  Program code:

  var ssid = 'ssid';
  var password = 'password';
  wifi.stopAP();
  wifi.connect(ssid, { password:password },()=>{wifi.save();});
  wifi.on('connected',()=>{console.log(wifi.getIP());});
  wifi.on('disconnected',()=>{console.log("WiFi network lost."); wifi.connect(ssid,{password:password});});
  
  

  When you first start wifi.on (‘connected’), it works:
  {
  "ip": "192.168.0.10",
  "netmask": "255.255.255.0",
  "gw": "192.168.0.1",
  "mac": "a4:cf:12:75:38:ec"
  }

  I turn off the router with my hands:

  E (113206) event: post event to user fail!
  E (115622) event: post event to user fail!
  E (118037) event: post event to user fail!
  E (120453) event: post event to user fail!
  WiFi network lost.
  WiFi network lost.
  WiFi network lost.

  Obviously wifi.on (‘disconnected’) - it worked.

  I turn on the router, I get a message from wifi.on (‘connected’):

  {
  "ip": "192.168.0.10",
  "netmask": "255.255.255.0",
  "gw": "192.168.0.1",
  "mac": "a4:cf:12:75:38:ec"
  }

  And that’s it. If I turn off the router again, then no events occur.
  Moreover, if you give the wifi.getIP () command when the router is off, then we get.

  {
  ip: "192.168.0.10",
  netmask: "255.255.255.0",
  gw: "192.168.0.1",
  mac: "a4:cf:12:75:38:ec"
  }

  (the router has been turned off for more than two minutes)
  That is, the board does not understand that wifi / network is no more.

  Question:

  1. So it should be or is it a mistake?
     
  2. If so, how should it be in this case to determine the absence of a network and reconnect to it?
     
     

  PS So far, the only working option I have found is the gateway ping once every 30 seconds, and if (rateTime> 1000) {e.Reboot ()};

  But I think this is not the best option :)
  PPS Sorry for the presentation - English is not my native language.

  I will be glad to any advice. Thanks.
