wifi key installation problem

Hello,

I have a small problem, I just installed mac OS mojave on my machine and my wifi key is not detected ...

I have a wifi reference key: Hercules wireless N USB 2.0 Mini Hwnu-lb-150 and a motherboard Asus maximus viii hero

I installed mojave with unibeats, I'm a beginner: D

Can you help me install it?
thank you in advance
