problème de connexion en wifi

[krutznikov]

Bonjour
Depuis quelque temps j’ai beaucoup de mal à me connecter à internet via wifi sous debian (version stable actuelle mise à jour). Je rencontre les même problèmes avec mes deux cartes wifi. Je ne rencontre pas ces problème quand je me connecte sous windows sur les mêmes réseaux donc le problème vient de mon système je pense.

Voici les problèmes rencontrés:
- quand je me connecte (via network manager), 8 fois sur 10 la connexion échoue, et j’ai alors ou bien le message “déconnecté” ou alors la fenêtre qui me redemande de taper le mot de passe du routeur
- quand je parviens à me connecter, le débit de connexion est si bas qu’il m’est impossible d’utiliser la connexion (de 0 à 150 octets par secondes d’après les statistiques réseau). Il faut parfois attendre quelques minutes avant que ce problème n’apparaisse.

J’utilise les cartes wifi atheros AR9285 et realtek RTL8187, et la ma carte réseau est une atheros AR8131.

Je précise que le problème vient peut-être de la gestion de ma carte réseau car je rencontre également un problème avec mon port ethernet: si je débranche le cable, il arrive que je ne puisse plus me connecter via ethernet en rebranchant jusqu’au prochain redémarrage.

Merci d’avance pour votre aide.

Il faut des infos plus précises sur ta configuration.

• le résultat de lsconfig (ou usb config) pour les 3 interfaces en question
• le résultat de ifconfig -a
• le résultat de iwconfig
• le résultat de iwlist nom-interface scan

“lsconfig” ou “usbconfig”? je n’ai pas ces commandes, je te donne ce que j’ai pu faire.

[krutznikov]

je remonte le post, personne ne peut m’aider? je ne peux continuer à utiliser mon système sans connexion internet…

[Grhim]

ça a l’air correct…

un wlan0 up pour la faire fonctionner

ensuite wicd ou en mode console ou autre , & tu te connect avec ton Id habituel

[piratebab]

il y a du monde autour de toi !

shuuuut!!

Ah, merci pour vos réponses.

les interfaces sont déjà up.

En ligne de commande je ne sais pas comment faire pour se connecter avec le WPA. Par contre j’ai essayé en utilisant wicd et là apparemment tout fonctionne normalement…

Le problème vient donc de network-manager, qui donne pour résultat un débit de 0 à 150 octets par secondes…

soit l’un soit l’autre, les 2 = conflit

[krutznikov]

oui j’ai déjà remarqué mais là il n’y a que le service network manager qui tourne tout seul. Pour utiliser wicd je dois le stopper, lancer le démon wicd et ensuite lancer son interface graphique.

Comment dois-je faire pour supprimer le démon network-manager du démarrage (sans pour autant le désinstaller)? dois-je simplement supprimer le fichier /etc/init.d/network-manager ou existe-t-il une méthode plus “propre”, un outil qui interface cette configuration? Je dois aussi ajouter wicd aux démons à lancer au démarrage mais je ne sais pas non plus commentle faire sans utiliser cron…

[Grhim]

pour enlever le processus au démarrage tu regarde dans les rc.d

pour wicd j’utilise la commande en console pour le demmarrer /etc/init.d/wicd start ( a la backtrack, je prefere faire comme cela ), pareil pour le démarrer en auto c’est dans les rc.d, fais un petite lecture sur le wiki pour apprendre a les gerer ;p

J’ai déjà lu des articles sur le fonctionnement des démons sur debian, mais un petit tour sur le wiki ne me ferait pas de mal en effet

merci pour ton aide.

Et n’oublie pas de commenter les lignes de ton fichier interfaces si tu utilises wicd, sinon il y a conflit.
Ta première idée de te connecter en ligne de commande éest bonne.
Il faut utiliser la commande iwconfig suivie du nom de l’interface et du paramètre à modifier.

Désolé d’avoir été si long à répondre, mais en fait le problème n’est toujours pas résolu.

Lorsque j’essaie de me connecter avec wicd, le processus bloque à “validating authentification…” pour finalement émettre l’erreur “mot de passe incorrect”. Comment pourrais-je résoudre ce problème? de quelles autres informations avez-vous besoin pour m’aider?

Merci d’avance.

ce que tu peux faire, c’est lancer wicd en ligne de commande depuis un terminal, et regarder ce que ça raconte.
wiki.debian.org/fr/WiFi/HowToUse#Wicd
L’autre solution , c’est de te connecter en ligne de commande et voir ou ça bloque.
Je ne me rappelle plus si tu as installé wpa-supplicant

[krutznikov]

alors j’ai suivi le wiki pour me connecter sur du wpa-psk en ligne de commande.

J’ai édité mon fichier /etc/network/interfaces comme suit:
auto lo
iface lo inet loopback
auto wlan0
iface wlan0 inet dhcp
wpa-ssid Livebox-6076_EXT
wpa-psk my_wpa_key

Après voila le résultat:
root@debian:/# ifup wlan0

Le problème viendrait donc de mon dhclient?

Je tente une question « toute bête », mais on ne sait jamais : la fonctionnalité WiFi est-elle bien activée sur ta Box ?

Biensur, quand je fais un iwlist scan j’obtiens un résultat normal. Ce n’est pas non plus un problème de filtrage mac, je me connecte actuellement à un répéteur wifi (d’où l’extention “_EXT”) et donc pas de filtrage. De plus, j’arrive à me connecter normalement quand je reboote sous windows.

[piratebab]

sous windows, est ce que tu te connectes dans les mêmes conditions (même point d’accés, en dhcp …) ?
On dirait dans tes logs que le point d’accés n’a pas de serveur DHCP, chose que ne diras pas un scan.
