EspruinoWiFi module builtin?

Requiring works. However, connect() succeeds only 1 out of 3 times (power off and on again). Here is my code:

// clean up before: E.setBootCode();

function onInit() {
  setTimeout(function() {
    require('Wifi').connect('SSID',{password:'mypassword'}, function(err) {
      console.log(err);
      if (err) return;
      require('net').createServer((conn) => {
        conn.pipe(LoopbackA);
        LoopbackA.pipe(conn);
        LoopbackB.setConsole();
      }).listen(23);
    });
  },3000);
}

// wait a few seconds, then: save();

With the 1v95 build connect() always succeeds.
