I have EndeavourOS with KDE. The problem is that I cant setup Wi-Fi in Network manager.
This is how it looks https://imgur.com/a/LoGV6Zq.

That might help? But i don’t have enough knowledge on this so i don’t know if it’s a problem or not. Obviously you are connected to Ethernet and that is working. Whether it’s blocking WiFi from working i don’t know.
