I know this is thread is a bit stale, but I wanted to post an answer for those who came across this searching like I did.
I got the same card (Fenvi FV8801) for my Windows machine because it was a great deal (2-in-1!). Well after a LOT of searching, it looks like this card does not work on macOS. It can recognize the Bluetooth, but not the Wifi signal. Until a driver is made for this card, it looks like you'll need to get different hardware.
As far as internet, you'll have to use Ethernet or get a different Wifi card. Keep in mind: Handoff, Location Services, and Unlock with Apple Watch only work with Wi-Fi. Ethernet will not enable these features.
