[ Résolu ] Plus de WiFi
Bonjour,
Après dix-huit mois de fonctionnement sans histoire, ma connexion wifi sous ubuntu hoary est inopérante depuis hier.
Matériel : - Portable ACER Aspire 9302WSMi. Wifi intégré.
Livebox Pro Inventel.
Connexion ethernet OK.
Connexion wifi sous XP OK.
Connexion wifi entre le Palm et la LB OK
Le wifi access visiteurs est détecté.
J'ai tenté de reparamétrer la connexion wifi, sans résultat.

Re : [ Résolu ] Plus de WiFi
Il me semble qu'il n'y a pas eu de mise à jour du noyau depuis la sortie de Hoary. Je ne pense pas non plus avoir fait quelque chose de spécial.

Re : [ Résolu ] Plus de WiFi
J'ai modifié le fichier /etc/network/interfaces comme indiqué sur la page
http://doc.ubuntu-fr.org/networkmanager
J'ai enlevé du tableau de bord l'autre applet de réseau dont j'ai oublié le nom.
J'ai supprimé la connexion wifi « orange access visiteurs » dans l'éditeur de configuration.
La connexion s'est rétablie.

Re : [ Résolu ] Plus de WiFi
Ça n'a pas duré longtemps. Déconnection au bout de 5 minutes, et impossible de reconnecter.
Le network manager ne voit plus la livebox même quand elle est en mode association.

Re : [ Résolu ] Plus de WiFi
J'ai remplacé Network Manager par Wicd.
Cette fois, je crois que le problème est réglé.
