Bonjour,
J’essaie vainement depuis quelques jours d’établir une connection en Wifi sur mon PC Portable, sous Debian 11, mais rien n’y fait…
Dernièrement j’ai tenté de mettre à jour la version du kernel comme suggéré via ce lien : How to install driver for Wi-Fi Mediatek MT7921 and Mediatek MT7961 in Linux - Ethical hacking and penetration testing
Mais idem, toujours pas de Wifi… 
Je vous poste ci-dessous plusieurs caractéristiques / captures :
