Can't activate Cubase 9 Pro on Macbook Pro 2017

Hi everyvody,
I’ve installed cubase 9 pro on my new mac, but I don’t know how to activate it with my usb dongle.
When I plug it in in the HUB (USB 3.1 to USB C), it interferes with my WiFi and I’m running out of internet.

What should I do?

Thanks anyway.

Solved, I found a solution by myself.
The WiFi was connected on a “standard” signal. I activated the 5g WiFi option (from the Router), then I connected to this 5g WiFi.
