Voici la résolution qui a permis de résoudre mon problème de wifi :

xubu1957 a écritPour nettoyer :
Le 11/02/2017, moko138 a écritPour supprimer tous ces fichiers de configuration devenus sans objets et marqués "rc", et uniquement ces fichiers, exécute :
dpkg -l | awk '/^rc/{print $2}' | xargs -r sudo dpkg -P
Regarde aussi > [résolu] plusieurs fois le même réseau wifi

Redémarre la Box, ensuite.

+ un redémarrage de mon PC, et plus de souci de wifi 😉

Bonjour,

Bonjour xubu1957,
J'avais déjà fait cette manip et j'ai remarqué que le "2" fonctionnait mieux mais quand je clique sur Livebox 9C40 j'ai l'impression que ça trouve bien le réseau mais ça me met ensuite "Echec de connexion"

xubu1957

Tu as un téléphone Android ?

Oui je suis connectée dessus pour répondre et essayer de régler le probleme

Fournis les noyaux présents :

et :

dpkg -l | grep -v ^ii

Pour nettoyer :

Le 11/02/2017, moko138 a écritPour supprimer tous ces fichiers de configuration devenus sans objets et marqués "rc", et uniquement ces fichiers, exécute :

dpkg -l | awk '/^rc/{print $2}' | xargs -r sudo dpkg -P

Regarde aussi > [résolu] plusieurs fois le même réseau wifi

Redémarre la Box, ensuite.

J'ai attendu un peu de temps pour être sûre que la résolution fonctionnait bien et c'est booooon 😉
Merci beaucoup à toi et je vais passer ce sujet en résolu
