    } else 
    {
        print("internet not ok")
        let alertView: UIAlertView = UIAlertView(title: "Alert ", message: "connect to internet", delegate: self, cancelButtonTitle: "settings", otherButtonTitles: "cancel")
        alertView.show()
        return       
    }       
}

func alertView(alertView: UIAlertView, clickedButtonAtIndex buttonIndex: Int)
{
    if buttonIndex == 0 {
        //This will open ios devices wifi settings
        UIApplication.sharedApplication().openURL(NSURL(string: "prefs:root")!)
