Thank you for your answers.

Anyway, with the code you provided the link, it keeps doing the same thing:

If I disconnect the router (no internet), it will not show any message.

When I reconnect the router, after some seconds, it shows the disconnected message and the connected one, at the same time. It doesn't detect the disconnection when the router is turned off.

    After some time I realized that the solution shown above doesn't work.
    Eventually it will fire when the Internet connection is lost but will no fire when the connection is restaured.

     

    The ONLY way I have found to monitoring the Internet connection state is:

    In xml:

     

    <field id = "offline" type = "boolean" value = "false" alwaysNotify = "true" onChange = "onOfflineChanged" />

     

     

    Have a timer (mine is fired every 10 seconds, but I think that it will be from 30 seconds to 1 minute).
    Then, when the timer fire, this is the code to run:

     

     

    function VerifyInternetConnection() ' Verify internet connection every 10 seconds (every minute?)
    print chr(10) + "Verify internet connection:"
    m.MainSceneDeviceInfo.ForceInternetStatusCheck().  ' This is de deviceInfo instance
    m.top.offline = NOT m.MainSceneDeviceInfo.GetInternetStatus()
    print "m.scene.offline = "; m.top.offline
end function

     


    Then, in onOfflineChanged() :

     

    function onOfflineChanged() ' m.top.offline has changed.
    if(m.top.offline)
        print "PlayerScene -> We are offline."
    else
        print "PlayerScene -> We are online."
    end if
end function

      You should be able to do it with 3 different ways:

      1. Create a timer that will fire every x seconds and inside the callback function instantiate a new device info object that will read the internet connection status:

      sub myTimerCallback()
    deviceInfo = CreateObject("rodeviceinfo")
    connectionStatus = deviceInfo.GetInternetStatus()

    ? connectionStatus ' this will show false or true
end sub

       2. Enable the internet status change event and inside the application main loop read the event and do something with it:

      sub main
  deviceInfo = CreateObject("roDeviceInfo")
  deviceInfo.EnableInternetStatusEvent(true)
  port = CreateObject("roMessagePort")
  deviceInfo.setMessagePort(port)

  while (true)
      msg = wait(0, port)
      msgType = type(msg)

      if msgType = "roDeviceInfoEvent"
          connectionStatus = msg.getData()
          ' do something with connectionStatus
      end if
end sub

      3. Dont use device info and create a timer that will fetch an image with x MB of size stored in some repo. Based on the time the image needs to load, compute the current internet speed or if the user is connected to internet

        Dear friend danielFav:

        Unfortunately the internet status change event don't work (at least for me).

        I even tried it again using your code, but it still didn't work. It fires the first time but never fires again.

        The only solution was using the timer.

        Now it works 100%.

        Thanks for your help. I appreciate.
