According to your Device Manager there are no "unknown devices" (ie devices which need a driver).

It's therefore possible that the LAN adapter is faulty such that it can't be detected any longer. In effect it no longer exists as far as Windows is concerned.

If that is the case, you'll have to buy & install a PCI or PCI-E NIC.

I tried to install the atheros driver but its not compatible to my mobo

I tried to install realtek but the deep sleep mode error appears and there's nothing i can do with it cause network adapter not showed.

I tried to get a lan card (Realtek RTL8139/810X Family PCI Fast Ethernet NIC) and install its drivers and the "Ethernet Controller" showed.

I tried to reinstall my lan card driver again and it works there's no any error that showed on device manager,but it has no internet,On network and sharing center/Adapter settings it says that the network cable unplug but its plug in correctly and the cable works on my laptop and tried other lan cable's and restarted the computer and check the bios setting on Lan card and its enable and started the system but still no internet it still says "Network cable unplug".

After that i tried to reinstall my lan card driver again and the driver showed an error (code 10)
