After two hours of not using i turn on my computer and see that i have no internet connection.

So i checked the ethernet cable (used on another device) and found out that the cable is functioning.

After that i opened device manager and saw that network adapter (Realtek PCIe GBE Family Controller) couldnt start properly (code:10). I updated the drivers and problem disapeared, but i still didnt have any internet connection whatsoever.

I ran some diagnostics utility from realtek´s oficial site and 4 out of 5 tests failed (Mac loopback, PHY loopback, IRQ, FIFO).

Is the problem on motherboard´s side or software´s?

Thank you for answers.
