XPS 9500 WiFi problems when USB plugged
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.

Is it a USB 3.0 device? I had a similar issue on a Precision 7560. Any USB 3.0 device would cause the WiFi to be effectively inoperable. USB 3.0 is known to cause interference to the 2.4 GHz band but none of the three laptops or three desktops I have on the office showed this behavior. I had to return the Precision 7560 because it appeared to be a defect and would be unacceptable if it is a design flaw. I have several USB 3.0 hubs and external drives that I need to interface with.
