Hi Adi10, You may try the following steps to check the issue. 1. Click Start button, type devmgmt.msc (without quotation marks) in the Search bar and press Enter. 2. Double click to expand "Network adapters". 3. Right click your network card and click "Properties". 4. Click Power Management, uncheck Allow the computer to turn off this device to save power and Allow this device to wake the computer boxes. 5. Click OK. Whats the result? If it does not work, I also suggest you update the BIOS and motherboard drivers. Good luck!Arthur Li - MSFT
