Where did network connections go in VirtualBox?

Question

Computer networks

In fact, there should be 3 of them.
Where did they go? I don't mind.
Plus, a virtual host adapter is also not created. It appears in the network center, but virtualbox does not see it.
How to fix it?
Thank you.

Answer 1

Most likely, you have lost (disabled or removed) the NDIS filter in the properties of the physical adapter (Local Area Connection -> Properties). It should be like in the screenshot - VirtulaBox Bridged Networking Driver
(There should be a screenshot, but habrastorage.org does not work)

Answer 2

Reinstall VirtualBox. Lost network driver.
