wpa_supplicant ne se connecte pas avec "ioctl [SIOCSIWENCODEEXT]: argument invalide" erreur!

Ubuntu Server 12.04 est installé sur mon ordinateur de bureau (en mode texte, X-Window n’est pas disponible) et je n’ai pas de connexion Ethernet câblée, seul un réseau sans fil est disponible. J'utilise un adaptateur sans fil USB TP-Link TL-WN723N pour me connecter au réseau sans fil.

Au début, a essayé d'utiliser iwconfigpour se connecter, mais a constaté qu'il ne pouvait pas être utilisé pour se connecter à un réseau sécurisé WPA2! Au début, iwconfigindique:

lo        no wireless extensions.

eth0      no wireless extensions.

et Sudo iwlist wlan0 scanning indique:

après avoir exécuté Sudo ifconfig wlan0 up, Sudo iwlist wlan0 scanning affiche:

J'ai installé wpasupplicantpour me connecter au réseau sans fil sécurisé avec WPA2. Mais il y a quelques problèmes avec ce paquet:

J'ai essayé de suivre les instructions dans Cette réponse

wpa_passphrase 'MYESSID12345' 'MYPASSWORD$1234567' > CONFIG_FILE

après la commande ci-dessus, j'ai édité CONFIG_FILE (/etc/wpa_supplicant/wpa_supplicant.conf) afin qu'il contienne:

network={
    ssid="MYESSID12345"
    scan_ssid=1
    key_mgmt=WPA-PSK
    psk="MYPASSWORD$1234567"
    proto=RSN WPA
    pairwise=CCMP TKIP
    group=CCMP TKIP
    #psk=1234567890abcdef1234567890abcdef1234567890abcedf1234567890abcdef
}

Ensuite, je lance wpa_supplicant -iwlan0 -c/etc/wpa_supplicant.conf -Dwext -dd. Le résultat est suite aux erreurs sur stderrname__:

après la dernière commande, wlan0 devient DOWN et je dois l'inventer à nouveau à l'aide de la commande Sudo iwconfig wlan0 up. Aussi, j'ai essayé de supprimer le paquet network-manager en me basant sur un commentaire disant que cela pourrait résoudre le problème, mais sans succès.

Également essayé de modifier le fichier wpa_supplicant.conf1 comme suit:

ESSAYEZ N ° 1 pour wpa_supplicant.conf

network={
    ssid="MYESSID12345"
    #psk="MYPASSWORD$1234567"
    psk=1234567890abcdef1234567890abcdef1234567890abcedf1234567890abcdef
}

ESSAYEZ N ° 2 pour wpa_supplicant.conf

network={
    ssid="MYESSID12345"
    scan_ssid=1
    key_mgmt=WPA-PSK
    #psk="MYPASSWORD$1234567"
    proto=RSN WPA
    pairwise=CCMP TKIP
    group=CCMP TKIP
    psk=1234567890abcdef1234567890abcdef1234567890abcedf1234567890abcdef
}

Tout d'abord, je pense que vous aurez plus de chance si votre routeur est configuré pour utiliser WPA2-AES et non pas TKIP.

Deuxièmement, je pense que vous prenez la route longue et compliquée alors que la route courte et facile fonctionnerait parfaitement. Tout d'abord, je vous suggère de sauvegarder votre fichier wpa_supplicant.conf actuel:

Sudo mv /etc/wpa_supplicant/wpa_supplicant.conf  /etc/wpa_supplicant/wpa_supplicant.bak

Ensuite, je vous suggère de modifier/etc/network/interfaces:

auto lo
iface lo inet loopback

auto wlan0
iface wlan0 inet static
address 192.168.1.150
netmask 255.255.255.0
gateway 192.168.1.1
wpa-essid MYESSID12345
wpa-psk MYPASSWORD$1234567

Bien sûr, remplacez vos coordonnées ici. Redémarrez l'interface:

Sudo ifdown wlan0 && Sudo ifup -v wlan0

Tester:

ping -c3 www.ubuntu.com

Si vous obtenez des résultats de ping, vous êtes connecté.
