Interface wlan0 non monté automatique suite passage à Etch

Support Debian
#1

Bonjour,

Il y a quelques mois, j’ai installé sans souci ma carte NetGear WG511v2 sous Debian Sarge en utilisant ndiswrapper. Nickel tout ce passait à merveille.
J’ai récemment fait une mise à jour de la distribution pour passer en Etch (upgrade-dist).
Depuis l’interface wlan0 n’est plus chargé automatique au démarrage, si je fais un ifup wlan0 tout ce passe bien. N’ayant rien changé entre temps, je séche.

dmesg | tail donne :

dans /etc/network/interfaces j’ai :

auto wlan0 iface wlan0 inet dhcp wireless-mode Managed wireless-essid xxxx wireless-freq 2.462G channel 11

le module ndiswrapper est bien chargé.
Si quelqu’un a une idée, je le remercie grandement.

#2

Tu as essayé de reinstaller tes drivers avec ndiswrapper?

#3

Merci Ashgenesis,
malgré la désinstallation (ndiswrapper -e wg511v2) et sa réinstallation cela ne change rien.
ndiswrapper -l donne :

Installed ndis drivers: wg511v2 driver present, hardware present

#4

je confirme que ton /etc/network/interface est bon, et devrait te lancer l’interface.
Tu as regardé les logs de boot (/var/log/messages en particulier) ?

#5

Voici mon /var/log/messages d’aujourd’hui, je ne vois rien de plus que la dernière ligne d’étrange (désolé c’est un peu long, merci):

C’est les seuls endroits dans les sources ou il y a ce message d’erreur je decortique de plus pres et je vous tient au courant…:slightly_smiling:

kestu hack ? A tous les coups il chope pas le signal, c’est tout.
Je ne crois pas que tu tires grand chose des sources…

Cela peut peut être aider, mais lorsque je démarre ou redémarre je vois furtivement un message d’erreur parlant de wlan0 et de flags mais je ne trouve pas cette erreur dans dmesg ou /var/log/message. Je ne maîtrise pas mais je soupçonne l’activation du service networking. Y a-t-il un moyen de trouver ce message ou de faire un démarrage “pas à pas” pour avoir le temps de noter le message ?
Par contre lorsque j’étais le pc (la j’ai le temps de voir les messages), le ifdown n’indique pas de message !
Merci

Finallement en éteignant le pc (et non en “était le pc” comme dit dans le message précédent), j’ai réussi à voir le message d’erreur (ifup -a ayant été fait durant la session):

deconfiguring network interfaces... cat: /var/run/dhclient.wlan0.pid : No such file or directory wlan0: ERROR while getting interface flags : No such device. done. cleaning up ifupdown: done
Ca parle peut-être à quelqu’un ?

Le message est normal, puisque ta carte n’est pas active, il ne peut pas l’arrèter.
C’est donc surtout sur son activation au démarrage qu’il faut se concentrer.
Mais à la limite, un truc pas plus mal pour la sécurité, ca serait de ne pas mettre ton wlan en auto, mais de faire un petit script à l’ouverture de session qui allume ton wifi, et eventuellement un autre qui l’eteigne à la fin:
ton wifi ne serait alors actif que quand tu utilises vraiment ta machine…

Comme tu le sugères MattOTop (ainsi que Navy sur http://www.wlanfr.net/forum.php?op=mess&pid=4221&pg=end#25118), effectivement en faisant un tour du côté des services activés au démarrage (via sysv-rc-conf), le service networking n’est activé que pour les runlevels 0,6 et S. En y ajoutant le niveau 2, j’ai retrouvé mon wlan0 au démarrage (bien que l’erreur persiste mais elle devait y être probablement avant aussi).
Merci à tous pour votre aide si précieuse. :smiley:
