Beelink CS-George Hi George, sorry for late reply I have just only got around to trying the files, the files in the link you gave me are the ones I originally downloaded and still give me the “The Realtek Network Controller was not found” when installing the LAN drivers.
EDIT:
After googling the Vendor and Device ID’s I was able to find someone with an asus motherbaord having the same issue. I downloaded the Intel LAN Driver V1.1.3.28 for Windows 11 64-bit—(WHQL) driver for the Intel I226-V ethernet controller from the ASUS website and now the ethernet ports are working, looks like there is a missing driver in that S13 folder.
