I tried with bridge and still couldn't get internet connection in guest system. In VirtualBox all ist still in default configuration like when I installed it and as Network is NAT configured and network adapter the one with 'Desktop' available for all and plugged in. In Windows 10 it seems to have still network and internet connection but I can't access any website. I am using VirtualBox 5.1.18 r114002 (Qt5.3.2) on Debian Jessie as host and in it I have set up Windows 10 as guest.Īll worked fine and I used it and once now there is no more internet connection in the guest system Windows 10 available.
