Q: After I upgraded my Windows8.1 OS to Windows 8.1 update, my Realtek LAN Utility works abnormally (It cannot show any hardware information like the picture showed below).

A: If customer upgrades Windows8 to Windows8.1 or to Windows8.1 update, the former version of Realtek LAN Utility may not be suitable for the new OS. In that case, customer has to install version or higher (It can be received from ASUS official website) to solve this problem. The normal status is like the picture showed below.
