Deconnexion intempestive du wifi
Bonjour,
J'ai depuis la mise à jour vers la 9.04 des gros soucis WIFI...
Je m'explique, il se déconnecte sans aucun avertissement et sans raison. J'ai déjà parcouru pas mal de forulm, de sujet fait des dizaines de manipulation en tout genre et rien ne fait...
J'ai juste remarqué que le probleme se produisait, quand on était a plusieurs connecté sur la borne wifi.
On utilise tous sur ubuntu 9.04, les cartes wifi sont toutes des ralink RT2561/RT61 et je précise que sous la 8.10 je n'ai aucun soucis.
J'ai essayé les drivers de ralink (tuto d'ici), ndiswrapper et suivis des dizaines de tutoriaux de la documentation en vain...
Voilà, je suis un peu perdu.... et je cherche un peu d'aide pour sortir de cette impasse...
Pour l'instant j'envisage soit d'essayer en ipfixe, quansd j'aurais retrouvé le tuto qui l'exlplique, soit de changez de carte wifi...

Re : Deconnexion intempestive du wifi
Salut,
J'ai eu des pb de deconnexion et de chute de debit avec Jaunty alors que ca allait avec Hardy.
J'ai essaye le gestionnaire de reseau wicd a la place de network manager et ca a resolu mes pb.
Pour les infos sur wicd : http://doc.ubuntu-fr.org/wicd
L'install de wicd supprime automatiquement nm et configure pour avoir l'applet reseau.
Good luck...

Re : Deconnexion intempestive du wifi
Bonjour, je vais essayer... quand j'aurais tout réinstallé... j'ai compilé le driver ralink... installé ça fonctionnait nicker hier et aujourd'hui tous les caractère de mon interfaces graphiques sont remplacés par des carrés et j'ai de nombreux freeze en tout genre sans que le wifi fonctionne.
Merci
J'ai installé WICD, installation et configuration hyper rapide, maintenant ça coupe moins mais ça ralentit juste fortement... pourquoi... qui sait...

Re : Deconnexion intempestive du wifi
Tu te connectes a un routeur ? Ou c'est ta box qui fait routeur ?

https://bugs.launchpad.net/ubuntu/+sour … bug/313218
