Is that an ArchLinux-specific driver?

Listed in order of likelihood of success:

A driver from Realtek, good for kernels up to 5.19:
https://www.realtek.com/en/directly-download?downloadid=8a2ffcae711e2dfb96e6f33843bbdc08

A driver on GitHub:

Another driver on GitHub:

Intel has a backport driver:
sudo add-apt-repository ppa:canonical-hwe-team/pc-oem-dkms
sudo apt-get update
sudo apt-get install backport-iwlwifi-dkms
reboot

3

I don't recall the exact origin of that driver as i've downloaded a few solutions, but any one that i've downloaded was either advertised as for debian, ubuntu or all linux distros.

The first link takes me to a download page that does not give me a download

I've attempted the solution in the second link. Here are my results:
