Bonsoir,

essaye cela :

sudo rm /var/lib/NetworkManager/NetworkManager.state

reboot et test a nouveau le wifi

Adlanovic · Le 27/05/2011, à 23:05

Merci Toutafai!!!!

Enfin de compte il a fallu que je reviens au contenu initial de /etc/interfaces, car j'avais ajouté deux lignes auparavant, j'ai redémarré et puis maintenant ça fonctionne correctement. toutefois j'arrive toujours pas à me connecté sur mon réseau wifi. lorsque j'inserts le mot de passe (clé wep 40/128-bit), y a rien.

Adlanovic · Le 27/05/2011, à 23:10

Résolu

toutafai · Le 27/05/2011, à 23:13

Oui, il faut un fichier interface minimaliste pour que network manager fonctionne correctement ;

Ps : un conseil, le wep ce n'est pas sécurisé, passe en WPA1 TKIP, ou mieux WPA2 AES !
