Re : [Résolu] Connexion wifi disparue !
Salut,
Comme l'indique le message "Hard blocked: yes", ton wifi est bloqué matériellement. Tu as donc, soit un interrupteur physique, soit un interrupteur sous forme de bouton tactile, soit une bascule à faire avec une touche de fonction (fn + f* ou étoile correspond à l'une des touches de fonctions), qui est en position éteinte.
A+
Un problème résolu ? Indiquez le en modifiant le titre du sujet.

Re : [Résolu] Connexion wifi disparue !
Encore merci, c'était un interrupteur discret que je n'avais même pas remarqué ! La connexion wifi fonctionne, je vais donc indiquer ce post comme résolu.
