Bonsoir,
sur mon PC2 (cf signature), je viens de migrer de ubuntu 14 à 18 récemment sans problèmes à l'installation (dual-boot windows 8.1)
Sous U14.04, tout se passait bien et la connexion wifi était parfaitement opérationnelle sous ubuntu ou même sous W$
Depuis le passage sous 18.04, il arrive qu'au retour d'une mise en veille le wifi ne soit plus accessible. Dans les paramètres systèmes j'ai alors : "aucun adaptateur wifi trouvé" ...
Si je redémarre le PC en général ça revient (mais des fois meme pas) et sous windws le wifi est tout à fait opérationnel.
L'accès aux connexions via l'icone en haut à droite indique "mode avion activé" mais ne permet pas de le désactiver....
Même l'utilisation de la combinaison de touches clavier (Fn+F2 dans mon cas) ne fonctionne alors plus ...
Auriez-vous des pistes de résolution de ce problème parce que malgré mes recherches je sèche lamentablement ....
Actuellement connecté en filaire, je joins ci-dessous le contenu de wificheck :
