Hali !
Örülök, hogy valamivel jobb a helyzet. Én ezt találtam a neten, ha rosszabodna a helyzet ezt is megpróbálhatod:
Go to Device manager which you find in properties of computer, then go to network adapters, click with the left button of mouse in the adapter, properties,go to advanced and click in reversing controller.
It happened the same with me, i followed these steps and worked.
Üdv
