Suddenly no more wifi in Windows install OOBE screen available.

[Sellfish86]

Hello,

 

I've got a problem concerning a repeated Windows 10 Pro installation on a Neo 15 notebook (Tongfang gk5cn6z).

After installing Windows properly a few times (to mess around with drivers, benchmarks, etc.) I wanted to do a final clean install. However, when Windows now gets to the OOBE "Let's set up a network connection" screen, there's no Wifi available anymore. Only Ethernet. Strangely, my Bios now shows a PXE Realtek PCIe GBE Family Controller which hasn't been there before. Loading defaults in BIOS, changing secure boot or switching between UEFI/Legacy doesn't help.

It also seems as if Windows doesn't install any drivers anymore at all during the installation.

 

Any idea what could have caused this and how to get back to a regular Windows installation? It scares me a bit to not know what's going on there.
