Salut,
Ton wifi est désactivé : tu dois avoir un interrupteur ou une combinaison de touche pour activer le wifi sur ton portable. Met le sur "On/marche" de préférence lors de la mise sous tension (= à l'allumage) du portable, car il se peut que ce soit mal géré en cours de session.
Tombé dans l'informatique étant petit, j'en ai fait mon métier. Utilisateur d'Ubuntu depuis novembre 2006, actuellement sous 20.04 x64 (Que d'évolution
depuis Dapper Drake ! Ça rajeunit pas ^^^).
