[Résolu] Probleme wifi
Bonjour,
J'ai installé Ubuntu 8.04 récemment. Tout marche sauf le wifi. J'ai pourtant bien installé ndiswrapper j'ai configuré le pilote wifi qui est maintenant installé et présent. Mon réseau ne détecte aucun réseau wifi. Et lorsque je configure une connexion wifi en allant dans "Se connecter à un réseau sans fil..." (clic droit sur NetworkManager) le wifi ne marche pas non plus. En effet la connexion créée échoue.
Je tiens à préciser que le wifi marche très bien sous Windows XP.
Je remercie d'avance à tout ceux qui feront preuve de bonne volonté en m'aidant !!
J'ai un PC portable Toshiba et une clé wifi Intel Realtek 8187B.
Voici les resultats des commandes :

Re : [Résolu] Probleme wifi
C'est bon, mon problème est résolu. Comment j'ai fait ? En fait j'ai juste mis à jour mon système pour passer de Ubuntu 8.04 Hardy à la version 8.10 Intrépid. Maintenant tous les reseaux wifis sont affichés.
Merci Olivier !
