[SOLVED] WiFi is not working at all (Xiaomi RedmiBook 15)

Hello, I wanted to install Arch on my laptop (Xiaomi RedmiBook 15) but ran into a problem that I can't connect to WiFi when installing (the laptop doesn't have an Ethernet port)

In the output of "lspci -k" command, this is the line about network controller:

- 01:00.0 Network Controller: Device 0b48:7922
- Subsystem: Device 0b48:7922
- Kernel modules: wl

In "iwctl" the output of the "device list" command is empty. Also when starting the installer I get these errors (in the last 4 lines the output is cut off for some reason):

- [    0.264217] ACPI BIOS Error (bug): Could not resolve symbol [\_SB.PCI0.GP18.SATA], AE_NOT_FOUND (20230331/dswload2-162)
- [    0.264233] ACPI Error: AE_NOT_FOUND, During name lookup/catalog (20230331/psobject-220)

- [    0.480749] ACPI Error: Aborting method \_SB.ALIB due to previous error (AE_A

- [    0.480849] ACPI Error: Aborting method \_SB.PCI0.LPC0.EC0._Q93 due to previo

How do I fix the WiFi, cuz using my phone as a USB modem is not very convenient. WiFi adapter model - "MediaTek Wi-Fi 6E MT7922 160MHz Wireless LAN Card".

I installed pwclient to download this patch, but when I'm trying to get it with ID on the patch page (13442710), it says "unable to fetch patch 13442710; does it exist?" How do I get ID of this patch?

Edit: I downloaded patch mbox from patch page, but I still don't know how to install it. But I found this string in it: "X-Patchwork-Id: 13442710". So this ID is correct, but I still don't understand why it doesn't work.

You'll have to patch and compile the kernel or at least the module - you can manually apply the 2 line change there.
