[résolu] PRO/Wireless 3945ABG Network Connection sur Ubuntu 8.04 BIS

Bonjour,

J'ai le même problème qu'ici apparemment : http://forum.ubuntu-fr.org/viewtopic.php?id=248564
Malheureusement, je n'ai pas encore résolu mon souci. Je n'arrive pas à me connecter à mon réseau WIFI et pire je n'en détecte aucun (wifi-radar).

Voici quelques informations sur ma configuration :

Pour avoir eu le même souci (même si ça n'est pas résolu pour moi, j'ai quand même la liste des réseaux proches), es-tu certain que la carte wifi est "allumée" ? Il y a parfois des "interrupteurs" à enclencher sur les pc, parfois au moment du boot de l'OS.

Je suis en dual boot avec Windows XP. L'interrrupteur existe bien et est sur la position ON.

En position off il est orange, en position ON il est bleu. Sous Windows cela fonctionne mais sous ubuntu il reste orange. Mais est-ce que cela signifie que la carte est désactivé, ou juste que la led ne change pas de couleur, mystère.

Mon problème est résolu après quelques heures de recherches grâce à ce site :
http://wlety.free.fr/forum/viewtopic.php?id=230

Pour moi cela a fonctionné après l'étape 2.
