sudo apt update sudo apt install linux-firmware sudo apt upgrade sudo reboot sudo pacman -Syu linux-firmware sudo reboot After reboot,
echo "options iwlwifi debug=0x0" | sudo tee /etc/modprobe.d/iwlwifi-debug.conf sudo update-initramfs -u sudo reboot Then check: If you see the exact string iwldebugyoyobin free
sudo wget -O /lib/firmware/iwl-debug-yoyo.bin \ https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git/plain/iwl-debug-yoyo.bin Set correct permissions:
