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:

coseos

#!/bin/bash
#
# Show Raspberry Pi eeprom configuration
#
# BOOT_ORDER= specifies the boot order which will allow you to boot from SSD connected over USB
#

sudo rpi-eeprom-config

coseos

#!/bin/bash
  
HOST=${1}
PATH=${2}

telnet ${HOST} 80 <<<EOF
    GET ${PATH} HTTP/1.1
    HOST: ${HOST}

EOF>>>

Razer Book 13 with Debian Bullseye: Fix Audio Problem

The Razer Book 13 is my second Razer notebook. The fine silver makes a nice difference to the beautiful black of the Stealh 13. Even though the technical specs leave some wishes open as 16 GB of RAM is the max, the look and touch is great. In my opinion this is the most beautiful non black notebook available in 2022.

Audio may not work out of the box though when you install Debian Bullseye (11) on your Razor Book 13.

When your output lists only the Dummy-device, fix that with the following command (run as root):
