WPA Enterprise

[koy]

Bonjour à tous,

Comme la plupart de vous savent déjà, l'interface d'Android ne vient pas avec une option pour se connecter aux réseaux wifi cryptés en WPA-Enterprise.

Mais grâce au root, on a néanmoins réussi à faire marcher tout cela:

http://pboos.ch/wordpress/2009/04/android-using-wpa2-enterprise/

J'ai essayé ceci sur mon Galaxy; la première chose que j'ai remarqué est que le fichier de configuration ne s'appelle pas "wpa_supplicant.conf", mais "bcm_supp.conf " (le chip wifi est différent des HTC je suppose).

J'ai donc fait les ajustements dans le fichier "/data/misc/wifi/bcm_supp.conf"; et je me suis déplacé vers un HotSpot fourni par l'université, qui requit WPA Enterprise.

A peine arrivé dans la zone wifi, mon portable essaye de se connecter au réseau, mais quelques secondes plus tard il ne répond plus à mes commandes; le téléphone est quasiment plus utilisable (car il devient tellement lent).

Voici un extrait du log, lors de la connexion:

Surtout les lignes suivantes me paraissent comme la cause de ce dysfonctionnement:

16:57:42.708: DEBUG/WifiHW(1069): 'DRIVER RSSI' command timed out.

Est-ce que quelqu'un ici a réussi à faire marcher ceci?

Et en modifiant le wpa_supplicant.conf situé dans /system/etc/wifi/ ca fonctionne pas mieux ?

(je demande a tout hasard hun, j'ai aucune idee du souci ^^)

Je ne l'ai pas encore essayé.

Mais le wpa_supplicant.conf ne semble pas être utilisé (le fichier est tout neuf, et aucun AP ajouté); en plus, quand le wifi est allumé, "ps" te donne ceci:

2917 0          2016 S   /system/bin/wpa_supplicant -Dwext -i eth0 -c /data/misc/wifi/bcm_supp.conf 
2920 1014        856 S   /system/bin/dhcpcd -BKL eth0   

(si je tappe la commande wpa_supplicant à la main, par "adb shell", ça ne marche pas)
