Se connecter à un point d'accès Wi-Fi protégé WPA/PSK

**YuGiOhJCJ** · 17/10/2011, 13h04

Bonjour,

j'essaie désespérément d'accéder à un point d'accès Wi-Fi protégé avec une clé WPA/PSK.

Pour me connecter je saisis :

Code :

$ sudo wpa_supplicant -ira0 -c/etc/wpa_supplicant.conf -d

Mon fichier de configuration est :
$ cat /media/sdc/wpa_supplicant.conf
network={
ssid="NEUF_43B4"
psk="..."
}

Et voici l'affichage que j'obtiens :

Et le processus continue d'écrire sur mon terminal donc je le stoppe.

Si l'on en croit 'lspci', ma carte réseau Wi-Fi est :

01:00.0 Network controller: RaLink RT2860

(elle est intégrée à mon ASUS Eeepc 1000H)

Et voici mon driver que je charge avec 'insmod' :
~/Ralink/2010_07_16_RT2860_Linux_STA_v2.4.0.0/os/linux/rt2860sta.ko

J'accède correctement aux réseaux qui ne sont pas protégé par clé.

Savez-vous comment je peux parvenir à me connecter à un réseau Wi-Fi protégé?

Merci.

il se peut j'avais eu le problème à l'époque avec un eeepc701 (les premiers), parce que certains encodages de clefs, ou les clefs trop longues ne pouvaient pas passer au niveau hardware de la pseudo-carte wifi et seul la clef wifi externe fonctionnait...

vu que tu as le cas sur une EEEPC aussi, c'est un secours à envisager si tu ne trouves pas de solutions software rapidement.

Merci pour cette solution de secours mais je souhaite réellement passer par le point d'accès WiFi sécurisé WPA.

Voici ce que iwlist me donne :

                        Authentication Suites (1) : PSK

J'ai essayé une autre solution software : mon driver permet de configurer ma carte wifi à l'aide d'un fichier '/etc/Wireless/RT2860STA/RT2860STA.dat'. Celui-ci est lu au moment où je charge le driver avec 'insmod' :
~/Ralink/2010_07_16_RT2860_Linux_STA_v2.4.0.0/os/linux/rt2860sta.ko

On peut préciser du WPA :

Code :

5
SSID=NEUF_43B4
Channel=11
AuthMode=WPA
EncrypType=TKIP
WPAPSK=masuperclewpa

Il est pris en compte car après cette modification, je ne peux plus me connecter aux points d'accès WiFi ouverts.

Mais même ainsi, après une demande dynamique IP avec mon client dhclient, je ne parviens pas à récupérer une adresse.

Pouvez-vous m'aider à configurer correctement ma carte?
