Answer 1

Hi,
go to Device Manager> network adapters, select your network adapter in use, click on the Power Management tab, uncheck the checkbox: Allow the computer to turn off the device to save energy. Click on the Advanced tab at the top and disable any options regarding energy saving, such as Gigabit auto disable, Energy Efficient Ethernet (EEE), Green Ethernet etc.
If necessary, update the network adapter drivers.

Answer 2

I'd check the pc manufacturer's site for the latest firmware, ROM bios, chipset and driver support packs.

Answer 3

Thanks for suggestions, but no luck.
Reinstalled everything still no internet connection.
It as if the ethernet adaptor is not working, although in device manager everything is ok.

Answer 4

I'd contact the manufacturer or ask in their forums about problems with the hardware.
