Problème de wifi [Resolu]

Support Debian
#1

Bonjours a tous.
Croyez le ou non, j’ai encore un problème de wifi. J’ai perdu l’affichage des réseaux avec Network Manager après avoir cliquer sur hiberné dans la barre de fermeture et de redémarrage du système…Quand je clic droit sur le diagramme réseau les deux onglet (activer le réseau et activer le réseau sans fil) sont activés. J’ai aussi refais la séquence de commende modprobe ath5k, iwconfig, ifconfig wlan0 up du tuto wiki.debian.org/ath5k. Quand je fais un scan en ligne de commende iwlist scan j’ai la réponce (no scan results).
J’aurais encore besoin de votre aide si précieuse.
Merci a l’avance.

salut :slightly_smiling:

tu peux peut-être essayer de modifier le fichier /etc/hibernate/blacklisted-modules
pour y ajouter le module qui gère ton wifi (soit ath5k si j’ai bien compris).

#3

Je suis bien d’accord de la black lister pour le prochain redémarrage après hibernation Baruch mais ça ne me redonne pas mon réseau wifi a court terme. J’aimerais le remettre en marche. J’ai essayé de trouver une solution sur d’autre communauté basée sur Debian et le bug d’hibernation est très bien documenté mais il n’y a pas de solution apparemment.
J’ai une autre question. J’aimerais savoir quel est la différence entre ath9k et ath5k pour mon système?

Si quelqu’un peut m’aider a redémarrer mon wifi ce serait très apprécié.
Merci a l’avance

#4

quand tu dis que tu as refait la séquence modprobe est-ce que ça comprend le déchargement du module (visiblement mal charger) avant de le recharger ?

genre :

[code]# modprobe -r ath5k

modprobe ath5k[/code]

#5

J’ai bien tout refais les séquences du chargement incluant la commende de démontage modprobe -r ath5k avant celle du montage modprobe ath5k. J’ai même réinstallé network-manager mais rien ne fonctionne. Network-manager ne détecte aucun réseaux wifi. J’ai fait beaucoup de recherche sur le net et rien qui m’aide a solutionner mon problème. J’aimerais bien mettre la main sur toute les lignes de commende avec leur définition qui traite sur le réseau wifi pour pouvoir les utiliser convenablement parce que la je suis dans la brume.
p.s: Quand je fais iwconfig mon access point n’est pas associé.

Merci a l’avance.

#6

tu peux toujours essayer
sudo iwlist scanning

qui va te lister tous les réseaux détectés par ta carte wifi
ou plus précisément
sudo iwlist [taIface] scanning
ça c’est juste pour tester voir si ta carte wifi peut encore détecter quelque chose

#7

Si tu regarde bien la dernière commende de mon premier post t’as suggestion y est Lou!$. No scan results. J’ai bien l’impression que ma carte wifi ne se charge pas bien ou est mal détecté.

#8

Ah désolé … Il y avait tellement de choses à lire …

#9

… va pas te plaindre, d’habitude c’est l’inverse !

PS : t’aurais pu choisir un pseudo plus facile à taper au clavier ! :slightly_smiling:

#10

Pour en revenir avec la citation de Baruch:

[code]quand tu dis que tu as refait la séquence modprobe est-ce que ça comprend le déchargement du module (visiblement mal charger) avant de le recharger ?

modprobe -r ath5k

modprobe ath5k

[/code]
Comment je fais pour vérifier si le module ath5k est bien chargé ou déchargé? :mrgreen:

Est-ce que quelqu’un peut m’expliquer le détaille des lignes qui ce rapporte a ath5k s.v.p?

#13

Tout ce que tu as à savoir c’est que si ath5k apparait dans le lsmod (lsmod | grep ath5k aurait suffi :wink: ) alors ton module est chargé. Après c’est du détail, la taille du module et le nombre d’élément du noyau s’étant enregistré auprès de lui pour faire en sorte qu’il ne soit pas décharagé.

#14

Bonjours tout le monde et merci a tous de vos réponses. Ma question aujourd’hui serait de savoir la suite logique de troubleshooting pour remettre mon wifi en état de marche.

Merci a l’avance!!

up :mrgreen:

Hem … j’ai essayé de lire un peu tout ce que tu as ecrit dans ton premier post, mais je crois que tu n’as pas fait

puis ensuite retente iwlist

Bon, ensuite faut que tu fasse

et retente un iwlist
je pense que ça va fonctionner.

En théorie.
Bonne chance.
