Timeout in CC3000 driver

During testing CC3000 and some other requires, sometimes the board stopped working and I had unplug to get it back to work.
After some testing, this workflow breaks Espruino

• send code to Espruino Board
  
• wait to get IP adress
  
• disconnect from Espruino Board
  

• connect to Espruino Board
  Some secondes later I get the timeout error (4101).
  Next another error comes up, "got '<' expected EOF at line 1 col 2...."
  Version 1v50 and this source

  
  var wlan = require("CC3000").connect();
  var ip;
  wlan.connect( "JUMWARE-LTE", "B73FD193D04293D", function (s) {
  if (s=="dhcp") {
  ip = wlan.getIP().ip;
  console.log("My IP is "+wlan.getIP().ip);
  require("http").createServer(function (req, res) {
    res.writeHead(200, {'Content-Type': 'text/plain'});
    res.write('IP is ' + ip + '<br>');      
    res.end();
  }).listen(80);
  }
  });
