Hi,

I have XPS 9500 with Core i9 and Killer 500s. I installed Kubuntu 20.04 and all works fine, but when I plug USB cable, I have missed packets and too big ping in my WiFi.
F.ex., if I plug external type-c monitor, WiFi drop my packets and increase latency. Unplug - all works fine. I tried several times and this problem repeated constantly.

How can I fix it?

Thanks.
