Bonjour à tous !
Je sais que c'est un problème récurrent pour ceux qui ont une carte similaire à la mienne depuis la dernière mise à jour : a plus le Wifi !
Je me permets de créer un nouveau sujet parce que les méthodes que j'ai lues ailleurs (notamment sur ce forum) n'ont rien réglé.
J'ai désactivé le secure boot : rien.
J'ai réinstallé le pilote : rien.
Soit je me suis planté dans une étape, soit je suis un cas. Quelqu'un a une idée ?
