[SOLVED] WiFi not working - No suitable firmware found

I've reinstalled my Notebook (Xiaomi mi book 12.5) and now Wifi isn't working. Before reinstalling I've used Debian and everything was working fine.
Already did a lot of research but can't find a solution why the firmware module doesn't load.

If I search for suitable firmware on git.kernel.org/pub/scm/linux/kernel/git … rmware.git the only module I can find is the already installed iwlwifi8000C.

Network controller: Intel Corporation Wireless 8260 (rev 3a)

Output of dmesg | grep iwlwifi

Maybe somebody can help me with this issue and also make me understand how the loading of firmware works.

Re: [SOLVED] WiFi not working - No suitable firmware found

It appears the linux-firmware package an optional dependency of the linux package is not installed on the system.

pacman -Fo /usr/lib/firmware/iwlwifi-8000C-36.ucode
usr/lib/firmware/iwlwifi-8000C-36.ucode is owned by core/linux-firmware 20190923.417a9c6-1

Re: [SOLVED] WiFi not working - No suitable firmware found

From a shallow reading, (maybe I'm wrong):
Surely is the same:

Install linux-firmware package.

Because not all of us are native English speakers, try no to use slang or abbreviations, thank you.

Re: [SOLVED] WiFi not working - No suitable firmware found

Thank you for your help! Installing the package linux-firmware did the job.

I thought this package is part of the basic installation.
