Problème : mon wifi ne marche plus

Tags: #<Tag:0x00007fae4e4af250>

Bonjour,

en allumant mon pc portable ce matin, je me rend compte que mon wifi ne marche plus.
Peut-être que c’est dû à au dernier apt-get update;apt-get upgrade.

Donc je redémarre network-manager :

root@localhost:/var/log# /etc/init.d/network-manager restart
[ ok ] Stopping network connection manager: NetworkManager.
[ ok ] Starting network connection manager: NetworkManager.
root@localhost:/var/log#

=> donc là rien à signaler

Mais au niveau du syslog, voilà ce que j’ai :

root@localhost:/var/log# cat syslog

root@localhost:/var/log# 

En scannant les interfaces, voici ce que j’ai :

root@localhost:/var/log# iwlist scan
lo        Interface doesn't support scanning.

wlan0     Interface doesn't support scanning : Network is down

eth0      Interface doesn't support scanning.

root@localhost:/var/log# 

Interface doesn’t support scanning : Network is down => donc j’ai relancer wlan0

ifconfig wlan0 down
ifconfig wlan0 up

Mais syslog me répond par ceci :

Oct  1 15:19:55 localhost kernel: [  661.457314] ADDRCONF(NETDEV_UP): wlan0: link is not ready

Mais au moins avec ifconfig wlan0 down/ifconfig wlan0 up, le wlan0 est devenu scannable (mais les informations sont trop bizarre avec des unknow partout :


root@localhost:/var/log# iwlist wlan0 scan
wlan0     Scan completed :

Une idée ? Merci beaucoup.

Post scriptum :

Voici mon fichier /etc/network/interfaces (que je n’ai pas touché) :

# This file describes the network interfaces available on your system
# and how to activate them. For more information, see interfaces(5).

# The loopback network interface
auto lo
iface lo inet loopback

# The primary network interface
#allow-hotplug eth0
#iface eth0 inet dhcp

Voici ma carte wifi et ma carte ethernet

# lspci 
08:00.0 Network controller: Atheros Communications Inc. AR9485 Wireless Network Adapter (rev 01)
=> Ma carte wifi

09:00.0 Ethernet controller: Realtek Semiconductor Co., Ltd. RTL8111/8168B PCI Express Gigabit Ethernet controller (rev 07)
=> Ma carte éthernet

J’ai aussi réinstallé le noyau et l’intramfs avec le paquets .deb de linux-image-amd64 et linux-image-2.6-amd64,
network-manager, network-manager-gnome, et firmware-realtek, mais ça n’a pas changé mon problème.

Sinon, il y aurait-il un moyen d’avoir l’avant dernère version de network-manager (downgrade) ?

Je n’ai plus l’avant dernière version dans mon cache.

pour confirmer que ça vient bien d’un problème de network manager, essaie de le désactiver et de configurer ton interface à la main, en CLI.
Ton wlan0 est désactivé lors de la config:

on dirait que c’est lié à un bouton d’activation

[quote=“fluo”]Sinon, il y aurait-il un moyen d’avoir l’avant dernère version de network-manager (downgrade) ?

Je n’ai plus l’avant dernière version dans mon cache.[/quote]
Oui, c’est tout à fait possible avec les snapshots : snapshot.debian.org/

Rien à voir avec ce soucis bien décrit par fluo…

…Dans un précédent fil sur un problème de wifi, quelqu’un a dit se coller à une page de wiki sur les soucis de wifis. Est-ce l’un(e) d’entre vous ? Quelqu’un aurait un lien ? Les soucis de wifi sont bien récurrents.

Ici :
http://www.isalo.org/wiki.debian-fr/Mon_wifi_ne_marche_pas!
Auteur(e)s : Agentsteel et Goodluck47

Désolé de polluer en faisant les questions et les réponses… pour ne pas résoudre le soucis du fil :wink: À sortir au prochain problème de wifi au besoin…

Bon, j’ai testé le noyau de la version précédente (merci à thunban pour snapshot.debian.org) et le noyau backports, et même les firmwares non-libres correspondants, mais mon wifi ne marche toujours pas. Je sais que ma carte wifi n’est pas cassé car le wifi marche avec le CD live de debian.

Donc je suis revenus sur la dernière version stable de wheezy. Mon interrupteur wifi est toujours allumé (sur on).

J’arrive à cerner les logs de wlan0 mais je n’arrive pas à les interpréter, à savoir :

-quand je fait /etc/init.d/network-manager restart, pour wlan0 syslog me répond :

root@localhost:/var/log# cat syslog | grep -i wlan
Oct  2 17:30:31 localhost NetworkManager[3428]: <info> (wlan0): now unmanaged

Oct  2 17:30:31 localhost NetworkManager[5754]: <info> (wlan0): deactivating device (reason 'managed') [2]

Quand je tape ifconfig wlan0 up, syslog me répond :

Oct  2 17:31:20 localhost kernel: [  566.953443] ADDRCONF(NETDEV_UP): wlan0: link is not ready

ça me tue vraiment. Une idée ?

pas d’idée, j’ai essayé de chercher sur

sans succés.
Essaie de changer de network manager (wicd par exemple)

Punaise, je mérite vraiment des baffes :blush: :079

Il fallait faire clic droit sur l’icone de network-manager dans le tableau de bord, et cocher “Activer le réseau sans fil”, et le problème est résolu.

Cela dit, ça c’est la solution “graphique”, alors que j’aurais voulu la solution cli.

Merci 1000 fois à toux ceux qui m’on aidé dans ce fil.
