Problems connecting to wifi ap

I had problems with one of my router so I did this feature:

  var boola;
  function lan() {
    wlan.connect(logon.ssid, {password: logon.pass}, function (s) {
      boola = true;
      if(s==='bad password') {
        if(debug)console.log('restart lan');
        lan();
      }
    });

    if(debug)console.log("Frida is my watchdog");
    if(debug)console.log(wlan.getIP().ip);
  } // end lan()
  setTimeout(lan,400);


  wlan.on('connected', function(s) {
    if(debug)console.log('Starter test', wlan.getIP().ip);
    if(boola) {
      boola = false;
      startTimeServer();
      if(debug)console.log('tilsluttet lan');
    }
  });
