I'm unable to use wifi in Arch Linux on my Lenovo Thinkpad X1 Extreme (Gen 2). I verified that the Intel AX200 network interface works through windows. I'm accessing the local network (and the internet through it) via a wired network connection.

I'm running Linux version 5.5.9-arch1-2 (linux@archlinux) (gcc version 9.3.0 (Arch Linux 9.3.0-1))

The systemd journal holds this info:

kernel: iwlwifi 0000:52:00.0: enabling device (0000 -> 0002)

Furthermore, ip link only shows the loopback and the wired nic.

When I look into the NetworkManager systemd logs, there seems to be at least an attempt to use the wifi:

manager[0x557825231080]: monitoring kernel firmware directory '/lib/firmware'.

Running rfkill list only yields this:

0: tpacpi_bluetooth_sw: Bluetooth
    Soft blocked: no
    Hard blocked: no
1: hci0: Bluetooth
    Soft blocked: no
    Hard blocked: no

I fixed it by installing the linux-firmware package.
