Hi @apparatus
yes, indeed I do have a rtl8821ce in this machine 
.
I have first tried to reinstall with latest Qubes OS iso installer highest kernel (6.5.6-2.fc37 instead of default 6.1.56-1.fc37), but it changed nothing 
.
I have a nice kernel panic in sys-net (which has this rtl8821ce device attached in its settings), and kernel driver in use is pciback while kernel module is rtw88_8821ce.
Having parsed the forum I understand I should blacklist rtw88_8821ce and use 8821ce instead (especially from here).
I will also find a way to download this module onto this machine (from another machine and a usb drive I assume).
I’m searching.
Thx
