Hey folks,
I have powered USB hub with ethernet port. This thing is plugged into my screen and then the screen is plugged into my laptop via usb-c cable (tunderbolt + PD). However after like an hour the ethernet is somehow disconnected and cannot connect again until I reload xhci_pci kernel module like:
sudo rmmod xhci\_pci ; sudo modprobe xhci\_pci; sudo service network-manager restart;
When I keep my laptop on over night it works in the morning which is weird because it should be disconnected. But after ~1h of use I get disconnected. Like someone is counting my packets :)
When disconnected network manager tries to connect but even after several attemts no success until I reload the kernel module.

```
Any idea where can I start sniffing?
