I have devoted some time over the weekend to this issue, but I still don’t have a good idea what was changed by an update and how to fix this. It is definitely not about driver signing because that phase is passed fine. And setupapi.dev.log does not contain any helpful information:

The only solution I can see so far would be creating a new NDIS 6 virtual network adapter driver…
