Yesterday I have installed Virtualbox on my win7 notebook and i have seen, that VB have install a network interface on the win7 network properties.
After installing Ubuntu guest on a new VB-instance, ubuntu cannot connect to the internet. Later into the night i have read somewhere that i should deactivate the network-interface and re-activate it.
So, i have deactivate this network-interface on win7 and after that, i have lost this and cannot re-activate it. The VB-Guest cannot connect now over bridget and so on.
How i get the network interface back into win7 for working the vb guest over bridge?
1) Open device manager
2) Under Network interfaces
You will find your lost adapter.
3) Right click it and click enable.
