Problème de connexion wifi depuis migration vers Intrepid
Depuis ma migration de Hardy vers INTREPID, NetworkManager n'affiche plus mon point d'accès public et je ne peux m'y connecter d'aucune façon.
Les seuls points d'accès qui s'affichent au démarrage sont:
WGnetwork auquel je me connecte avec une clé WEP
MyPlace, réseau sécurisé FON avec clé WPA auquel je ne peux me connecter car je n'arrive pas à configurer wpa-supplicant; au bout de quelques minutes ce réseau ne s'affiche plus dans NetworkManager
Les réseaux de mes voisins ne sont plus détectés
Mon point daccès public FON_FREE_INTERNET n'est pas détecté;
Je pense que je ne pourrai pas me connecter à un point d'accès public en voyage
Avec Hardy tout fonctionnait sans problème.
Voici un relevé des différentes commandes:

Re : Problème de connexion wifi depuis migration vers Intrepid
Bonjour
a peu pres le meme probleme pour moi
Mon reseau freebox n'est pas detecté.
Les reseau wifi de mes voisin sont detectés. Je peux me connecte a mon reseau en me connectant sur "reseau wifi invible", alors que le reseau wifi n'est pas invisible dans les conf de la freebox.
Deconnection du reseau assez souvent ( toute les heures environ).
Si quelqu'un a une idée...
Merci
