Manjaro kernel upgrade & wireless drivers

then enable grub menu on boot
see GRUB Menu Not Showing On Boot, Boots into Default Kernel Instead - #4 by stephane

after you can add any kernel ( be careful on arch motherboard and minimum version required )
you will need internet ,
boot on kernel 5.15 , and add others kernels

sudo mhwd-kernel -li
ls /etc/mkinitcpio.d/*.preset
ls /boot/*
ls /lib/modules/*
sudo pacman -Syy
sudo mhwd-kernel -r linux56
sudo pacman -S linux515-headers
sudo mhwd-kernel -i linux61 
sudo mhwd-kernel -i linux65
sudo mhwd-kernel -i linux66

do not keep EOL kernels you will keep EOL modules
