Perte de connexion wifi juste après l'installation

Eric Gosselain · Le 15/04/2009, à 00:17

Bonjour

Je viens d'installer ubuntu 8.04
La première chose que j'ai voulu faire est de parmètrer ma connexion wifi (pas de connexion fixe disponible)

Je suis aller dans l'outil de réglage du réseau
j'ai déverrouiller
choisi la connexion sans fil
choisi les propriétés

J'ai désactivé le mode itinérant
J'ai retrouvé mon réseau domestique (BBOX 2 Belgacom pour ceux qui connaissent)
J'ai encodé ma clé wpa
et chois la configuration automatique (DHCP)
Puis Valider

Pas de message d'erreur

Ensuite j'ai voulu surfer avec firefox 3 beta 5 préinstaller et là rien, pas de connexion

J'ai voulu relancer le parmètrage mais je ne trouve plus ma connexion wifi domestique

Comment me brancher à internet?

J'utilise une clé wifi USB D-Link dwl-G122 C1, j'ai vérifié sa compatibilité elle devrait marcher sans problème,

Voici les parmètres systèmes demandés

Merci de votre aide

Eric

A priori, rien d'inqueitant: réesaye de te connecter par wifi apres un redémarrage

(euh, c'est pas pour dire, mais il ya un peu beaucoup (trop) de detail, bon, ca aide, mais ca décourage aussi un potentiel aideur, perso, j'ai mis bien 10 minute pour tout lire, c'est un peu comme l'omelette choucroute lentille... )
