Salut,
Je suis pas très doué avec le wifi... j'essaye de configurer un raspberry-pi pour qu'il se connecte au réseau en wifi. L'idée c'est de l'avoir sans écran ni clavier.
J'ai branché un (vieux) point d'acces 802.11g, configuré sur le canal3, sans aucune protection d'aucune sorte.
Le point d'acces boot, le dongle wifi est reconnu et il voit le point d'access:
iwlist wlan0 scanning:
Cell 05 - Address: 00:09:5B:5B:B1:A9
Channel:3
Frequency:2.422 GHz (Channel 3)

Ensuite j'essaye de m'associer à ce point d'acces:
iwconfig wlan0 ESSID fournet channel 3 ap 00:09:5B:5B:B1:A9
cela a l'air de marcher mais dans les logs on voit que l'association tombe de suite:

Quelqu'un a une idée de ce qui peut bien se passer ?
merci d'avance.
