impossible de se connecter en wifi

salut, je suis nouveau sous ubuntu et je n'arrive pas a me connecter en wifi avec la livebox sagem.

j'ai reussis a allumer la diode bleue mais il m'est impossible de detecter un reseau wifi.

quand je cree un reseau sans fil j'obtient bien les barres de connections mais elles sont blanches et ce n'est pas le nom de ma livebox qui est indiqué mais "unknown".

merci de votre aide.

Re : impossible de se connecter en wifi

apparemment le driver est opérationnel sous Jaunty (c'est l'occasion de mettre à jour)

sinon bonne chance

Re : impossible de se connecter en wifi

merci

sous jaunty j'arrive a me connecter en wifi mais la livebox est connectée a 0%.

donc si vous avez des conseils je suis preneur.

Bonne journée.

Re : impossible de se connecter en wifi

connectée .. c.a.d. que tu à rentré le code wpa ?

as tu bien fait la manip avec le bouton de la LB pour permettre le filtrage MAC?
