How to I proceed to install a new WiFi+BT Card?

Hi there!

I'm currently working on my Lenovo Ideapad 330s (14-IKB). I managed to get everything working besides WiFi (and iMessage which will be done later on). This is due to the installed Intel 3165 Card, which has no available drivers. There was some Development going on in 2016, but that died after 3 Weeks.

​

So here's the question:

Do I have to reinstall Mojave in order to use the new Card or is it more like plug and play?
