Windows installed but no network

Hello, I usually do not have any problem with the network after a windows installation. I leave everything by default and the VM would DHCP the network. Well, something has changed as I do not have network anymore. The installation has Networking: default (sys-firewall) (current), 50 GB System storage created on an Empty standalone qube(install your own OS), with launch settings after creation and under advanced tab 4096 MB Initial memory, kernel none and Virtualization HVM. How can I make the network work?
