Help! Virtual Box Host-only Network does not work

[Nike.C]

I installed Virtual Box in my computer and the host-only network works fine.
But when I go to the Internet caf'e Install the Virtual Box , thouth the host-only network is installed, it does not work.No pack receve or send.




I open the global setting check the network state and there is no ip adress.



Why is that ? Is it about authority ?
