Ethernet Driver Not Working After Win10 Installation

Hi there!

So I tried to update from Windows 8 to 10 last week.
That didn't work for me, so I had to format everything and install Windows 10 afterwards.

At first neither W-LAN nor LAN would work. Then I un- & reinstalled the W-LAN driver so now everything's fine except for my ethernet connection.

- Adapter is enabled
- I have un- & reinstalled the driver multiple times (even tried compatability mode, since some sites state that the latest version for AR8161 only supports win 8)
- I was about a thousand times in the properties menu of the ethernet adapter

The full name of the adapter is "Qualcomm Atheros AR8161 PCI-E Gigabit Ethernet Controller (NDIS 6.30)"

I really do not want to lose all the stuff I already configured, so if some of you can help me with this issue I would be very grateful.

Huge Edit:

I just ran diagnostics on the ethernet adapter and after trying to fix some network protocols Windows prompted me with this.
So I tried to fix this by entering

Code:

Dism.exe /online /Cleanup-Image /StartComponentCleanup

Code:

sfc /scannow

Code:

Dism /Online /Cleanup-Image /RestoreHealth

Code:

sfc /scannow

in cmd which sadly didn't do the trick.
Neither did entering

Code:

netsh int ip reset c:\resetlog.txt

in cmd (admin ofc) after editing the permissions for the "26" folder in HKEY_LOCAL_MACHINE/SYSTEM/CurrentControlSet/Control/Nsi/{eb004a00-9b1a-11d4-9123-0050047759bc} so the group "everyone" has "full control".

Long story short: I am still stuck here w/ the "One or more network protocols are missing on this computer" -problem.
