Carte wifi et réseau sans fil detectés mais connexion impossible

majo · Le 16/02/2008, à 15:46

Bonjour à tous,

Novice sous Linux, je souhaiterai que vous me veniez en aide pour configurer ma connexion wifi (via une livebox sécurisée par une clé WEP / dhcp activé).

Ma carte wifi est, à priori, bien détectée mais la connexion ne s'établie pas...

L'adresse MAC de ma carte wifi fait partie des adresses valides sur le filtrage MAC de ma livebox.

De plus, j'ai testé la connexion wifi sous Windows 2000 et XP : aucun problème, la connexion s'établie immédiatement.

Configuration :
PC : DELL Optiplex GX270SD.
OS : Kubuntu 7.10 Gutsy Gibbon seul : pas de dual boot avec Windows.
Modem Wifi / Routeur : Livebox.
Carte Wifi : D-Link AirPlusXtreme G (G 108) DWL-G520 PCI (device : atheros AR5212/AR5213 Multiprotocol MAC/baseband processor).

En utilisant K-NetworkManager, je n'obtiens rien de mieux...

Merci d'avance pour vos réponses.
N'hésitez pas à me demander plus d'infos si nécessaire.

Salut

Vu ta carte atheros AR5212 et ta distrib Gutsy, ta connexion devrait etre ultra simple or tu n'as apparement rien dans ton /etc/network/interfaces. Tu as donc dû passer par Wicd ou wifi-radar (à moins que ce ne soit KwifiManager, je mettrais ces trois là au repos)... Je crois que l'os est là
Tu as alors une interface ath0 qui scan alors que ton Lshw annonce «logical name: wifi0»

je ferais un ifdown ath0 voire plus pour virer ath0 fermement.
puis sudo gedit /etc/network/interfaces
alors j'y ajouterais

iface wifi0 inet dhcp

auto wifi0

NB : enregistres en sortant

ensuite je virererais les clés sur la box (son signal est faible) le temps de choper une fois le réseau, sans oublier le bouton d'association ; quelques vérifs si ça tourne, ensuite tu peux passer aux clés.

Salut,

Il faut que tu modifi ton fichier /etc/network/interface ainsi :

auto lo wlan0
iface lo inet loopback
iface wlan0 inet dhcp
        wireless-mode managed
        wireless-essid ton_ssid (le nom de ta livebox)
        wireless-key ta_clé_wep

et ça devrait rouler!!

Salut j'ai aussi une carte comme celle là et N-M suffit:
Pour une connection avec l'applet Network-manager

modif du fichier interfaces

echo -e 'auto lo\niface lo inet loopback\n' | sudo tee /etc/network/interfaces

et connecte toi avec network-manager (2 tv en haut a droite à coté de l'heure)!

Ca donnes ça N-M
