Connexion Wifi impossible mais reseau wpa detecté
Bonjour,
Je viens d'arriver sur Ubuntu. Tout se passe tres bien sauf pour ma connexion wifi. Impossible de me connecter par le biais de NetworkManager ou Wicd.
Je pense avoir fait tous les forums a ce sujet mais pas de résultat correct pour ma part.
A priori, il y a pas mal de problème avec la carte Broadcom 4306 rev2 ou j'ai essayé plusieurs drivers (b43legacy, driver de windows xp avec ndiswrapper...)
J'espère que quelqu'un a une idée pour m'aider.
Merci

Re : Connexion Wifi impossible mais reseau wpa detecté
Merci pour ta réponse
Je n'ai pas trouve de solution sur le lien que tu m'as donné.
Par contre, je me suis aperçu que le driver b43legacy n'était plus dans les "pilotes de périphériques".
En installant Ubuntu 9.04, le pilote s'est installé automatiquement. J'ai du le supprimer en faisant différentes manip.
A priori, je l'ai réinstallé en suivant un forum mais il n'apparait toujours pas.
Est-il possible de revenir l'origine de l'installation uniquement concernant le reseau ?
