Reminds me of the MacBook Air that I have (2018 model).
When I connect my USB 3 hub to it, I lose my WiFi :(
I Googled it when it happened a while back, and apparently other people have this problem with the MacBook Air too.
Some choose to shield the USB 3 cable with tinfoil. Personally I opted to connect a USB 3 Ethernet interface to the hub and use wired Ethernet when I use the hub.
