Re : [Résolu] Probleme de wifi trouvée mais pas de connection

est ce normal que la clé sécurité change à chaque fois que network manager me la demande ?

Re : [Résolu] Probleme de wifi trouvée mais pas de connection

est ce normal que la clé sécurité change à chaque fois que network manager me la demande ?

Ce n'est pas qu'elle change, c'est que NM l'enregistre en binaire.

Pour t'en convaincre tu fais

wpa_passphrase Livebox-DE79 "Ta phrase clé ici"

(Tu remplace ci-dessus le "Ta phrase clé"... par ta phrase clé, bien sûr !)

Et tu auras la PSK qui est enregistrée par NM.

En principe ça doit correspondre

Encore l'histoire de la merde de la livebox et sa procédure d'association, à tous les coups !

bon maintenant je la détecte plus, je fait se connecté a un réseau sans fil mais toujours pas de connection.
l'ordi portable sous ubuntu de la maison n'arrive plus à se connecté en wifi maintenant.

j'ai essayé plusieurs fois le mode association en vain

Re : [Résolu] Probleme de wifi trouvée mais pas de connection

Résolu

réinstalle livebox et supprimer les connections de network manager
