[Wifi]Impossible de se connecter (résolu)

[chindit]

Bonjour à tous

Je viens d'installer Arch sur mon eeePC et d'y mettre gnome3.
Le problème que j'ai est que je n'arrive pas à me connecter au wifi.

/var/log/messages.log dit ceci :

Bien entendu, j'ai été lire la doc sur le Wifi.
J'ai notamment regardé le résultat de iwconfig:

Code : Tout sélectionner

wlan0     IEEE 802.11bgn  ESSID:off/any  
          Mode:Managed  Access Point: Not-Associated   Tx-Power=15 dBm   
          Retry  long limit:7   RTS thr:off   Fragment thr:off
          Power Management:off

D'après des recherches, je sais qu'il à un problème parce que "Not-Associated" n'est pas normal" mais je ne sais pas comment le résoudre.

J'ai également essayé ceci wpa_supplicant -i wlan0 -c /etc/wpa_supplicant.conf (mon wifi est en WPA2-TKIP et, oui, j'ai pensé à configurer le fichier avant de lancer la commande) mais ça a échoué :

En outre, lorsque j'essaie graphiquement, je n'ai pas accès aux options du wifi (généralement, je peux y aller une fois puis le bouton apparaît grisé jusqu'à ce que je redémarre).


J'avoue être perdu. Que dois-je faire pour que le wifi fonctionne?
Merci d'avance à tous

P.S.: ma carte Wifi est une Atheros AR9… Et j'ai vérifié, le driver ath9k est bien présent

D'après le LOG, j'avais deviné que c'était l'IPv6 qui posait problème.
J'avais coché «Ignore» mais ça n'avait pas fonctionner.

En fait, en choisissant "Lien à «Local»", ça fonctionne.

Persévérance, what else?

Salut,

J'ai quasiment le meme probleme, mais je ne trouve pas le choix "Lien à", peux-tu me dire où il se trouve?

Mervi d'avance!

Finalement, j'ai également trouvé par moi-même ^_^

Le choix "Lien à" peut être fait grâce à NetworkManager (j'utilise Wicd) mais cela n'a pas résolu mon problème (j'obtenais bien une IP mais impossible d'aller sur internet). En revanche, utiliser une IP statique me permet bien d'accéder sur internet.
