After reinstalling the system, the wifi driver stopped working

Previously, everything worked for me without any settings, but now I get errors in dmesg:

My device shows up in lspci as:

00:0c.0 Network controller: Intel Corporation Device 31dc (rev 03)
        DeviceName: WLAN
        Subsystem: Intel Corporation Device 0034
        Kernel modules: iwlwifi

I still did not understand what drivers my device needs, especially in lspci and other programs it does not display correctly, that is, it does not say something like: Realtek W3223
How to fix this problem?

pacman -Qi linux-firmware

Yes, I do not have this package
But why doesn’t it install automatically when installing through pacstrap? The kernel also stopped installing itself

Was also a dependency for linux, but dropped in https://git.archlinux.org/svntogit/pack … ef45974373

If you were following the official installation guide, you would have installed these packages.
