Bonjour,
J'ai un problème avec ma clé usb wifi. Je viens de réinstaller ubuntu 20.04 LTS en dual-boot avec windows sur mon pc fixe et il n'y a pas de wifi.
J'ai fait un wificheck avec la commande suivante :
wget -N -t 5 -T 10 https://framagit.org/cracolinux/wificheck/raw/master/wificheck && chmod +x wificheck && ./wificheck
Voilà le retour :

Je ne sais pas vraiment comment faire.
Auriez-vous une idée ?
Merci d'avance à la communauté !
NOTA : La solution de L. Finger donnée au poste #26 + la mise en place la gestion avec dkms au poste #30 ont fonctionné.
