[systemd] Wlan0 down, Up impossible. (résolu)

Publié : sam. 17 nov. 2012, 09:11

Hello,

Depuis mon passage à systemd, impossible d'utiliser mon Wifi.Avec Initscripts, tout fonctionnait parfaitement.

J'utilise WICD comme interface graphique.

Le module wlan0 est bien chargé si je fais un "systemctl --all", ainsi que Wicd client.

Code : Tout sélectionner

sys-subsystem-net-devices-eth0.device                loaded active   plugged       AR8151 v2.0 Gigabit Ethernet
sys-subsystem-net-devices-wlan0.device               loaded active   plugged       Centrino Wireless-N 100
...
wicd.service                                         loaded active   running       Wicd a wireless and wired network manager for Linux
...
network.target                                       loaded active   active        Network
Le statut de wlan0:

Code : Tout sélectionner

[thomas@archasus ~]$ systemctl status sys-subsystem-net-devices-wlan0.device
sys-subsystem-net-devices-wlan0.device - Centrino Wireless-N 100
	  Loaded: loaded
	  Active: active (plugged) since Sat, 2012-11-17 08:28:15 CET; 49min ago
	  Device: /sys/devices/pci0000:00/0000:00:1c.1/0000:03:00.0/net/wlan0
Cependant; impossible de scanner les réseaux disponibles, que ce soit avec Wicd ou la commande suivante:

Code : Tout sélectionner

[thomas@archasus ~]$  iwlist wlan0 scan
wlan0     Failed to read scan data : Network is down
De plus, impossible de monter wlan0:

Code : Tout sélectionner

[root@archasus ~]# ip link set wlan0 up
RTNETLINK answers: Operation not possible due to RF-kill
Mes capacités à lire les journeaux systemd et manager mon réseau étant limitées, j'ai besoin de votre aide...

Voici la sortie complète de "systemctl --all" au cas où vous y trouveriez un conflit de services (entre Wicd ete network par exemple).

Code : Tout sélectionner

[thomas@archasus ~]$ systemctl --all

Salut,

Les journaux se consultent en root.
Que donne systemctl status wicd ?

Tu n'aurais pas éteint physiquement le wifi par mégarde ?

Bon j'ai redémarré sous Windows pour voir. Le Wifi ne captais pas non plus. Après désactivation/activation du wifi via l'icone sous Windows, j'ai re-capté. Redémarrage sous Arch et tout refonctionne...

Je ne pensais pas que la désactivation sous Windows était matérielle et impactait Linux. J'aurai appris quelque chose.

Merci!
