Hi,
Go into Device Manager - Double Click the device - Driver's tab - Uninstall - when complete reboot.
That will refresh the driver's stack.
If still needed check with ASUStek Support, their drivers, and forums - be sure to ask about any known issues. Then check with Intel for the latest available driver versions.
