AX88179 USB 3.0 to gigabit ethernet

I have some USB3.0 to gigabit ethernet adapter but was told AX88179 chipset based is more stable than realtek. Hence i tried buy Fosmon USB 3.0 to RJ45 10/100/1000Mbps Gigabit Ethernet LAN Network Adapter AX88179 QF QFN68 Chipset (Black) from Amazon to give it a try. It ships with a CD and because nowadays my laptop contains no DVD drive i have to either wait or finding the driver online. i did manage to find AX88179 driver on its manufacturer website, install but it doesn't work. Look like i have to try it elsewhere.

to be continued....
