I have a defective/damaged motherboard ethernet jack (enp0s20) on this old PC that I’ve since worked around by getting an network interface card that slots in a PCI slot (enp2s8).
The issue I’m having:
When my session starts, it seems to want to use the defective enp0s20 over the NIC. I’m not sure if this is something I need to configure with a terminal command or if KDE has an option to select the default network device to use.
