No puedo usar wifi en Arch Linux en mi Lenovo Thinkpad X1 Extreme (Gen 2). Verifiqué que la interfaz de red Intel AX200 funciona a través de Windows. Estoy accediendo a la red local (y a Internet a través de ella) a través de una conexión de red por cable.
Estoy ejecutando la versión 5.5.9-arch1-2 de Linux (linux@archlinux) (gcc versión 9.3.0 (Arch Linux 9.3.0-1))
El diario systemd contiene esta información:

Además, ip linksolo muestra el loopback y la NIC cableada.
Cuando miro los registros del sistema NetworkManager, parece haber al menos un intento de usar wifi:

Lo arreglé instalando el linux-firmwarepaquete.
