Hello... I bought like HomePlug adapter tried to run it but then saw that I don't even have ethernet network. Tried to install drivers but at the finish it shows message "The Realtek Network Controller was not found. If Deep Sleep is enabled Please Plug the Cable." But my wifi works... Idk. Anyways I tried to search for solution online and I tried these steps.
Power off pc and wair 10 minutes or more.
Remove RAM.
Install chipset drivers.
Nothing works.
People say that I have to disable "Allow the computer to turn off this device to save power." Well it's not possible since I can't install the drivers at the first place. Any more solutions I could try?
