Cannot connect to Wifi after deep sleep.

Thanks. I tried it in the following way but with the same result (even without deep sleep):

var WIFI_NAME = "";
var WIFI_OPTIONS = { password : "" };

function onInit() {
  wifi = require("Wifi");
 // Call to an function that kicks off my code
  setInterval(function() {
  connectToWifi();
  //setDeepSleep(1);
  }, 10000);
}

function connectToWifi(){
  console.log("connectToWifi");
  var wifi = require("Wifi");
  wifi.connect(WIFI_NAME, WIFI_OPTIONS, function(err) {
  if (err) {
    console.log("Connection error: "+err);
    return;
  } else {
    console.log("Connected!");
    getPage();
  }
    console.log("End");
  });
}

function getPage() {
  require("http").get("http://www.pur3.co.uk/hello.txt", function(res) {
    console.log("Response: ",res);
    res.on('data', function(d) {
      console.log("--->"+d);
    });
  });
}
