coseos / Razer Book 13 WiFi Intel AX-201 with Debian 11.md

Razer Book 13 WiFi Intel AX-201 with Debian 11

The Razer Book 13 includes a rather new Intel AX-201 WiFi that is not supported out of the box by Debian 11 on a fresh installation (as of 2021-12-30).

To make your WiFi adapter work, get the (latest) Firmware from https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git. Using https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git/snapshot/linux-firmware-20211216.tar.gz worked well for me.

You have to untar the file and look for the driver files. Copy the files to the /lib/firmware/ folder and reboot your system.

To copy the files from the extracted archive, use:
