Re: [Wifi] Impossible de me connecter...

Le système de "cryptage" auquel tu essaie d'accéder ne serait pas du WPA par hazard ?

Toi tu essaie de t'y connecter en utilisant un "cryptage" WEP (PS : la
clef à saisir aprés la commande key doit être de l'hexadécimal)

Bonjour bonjour...
Voila, je tentes desesperement de me connecter au reseau de mon ecole
en WiFi. LE probleme doit tres certainement provenir de ma
configuration. Toutefois, je ne comprends pas pourquoi car j'arrive à
me connecter à d'autre AP mais toujours en mode non securisé (genre
dans le bar où je vais...).
Avant toutes choses, je suis sur un IBM T42 et une carte Wifi Intel
pro/wireless 2200bg. J'ai les "drivers" (je ne sais pas si c'est le
bon mot) ipw2200-firmware 2.3 (peut etre me faut-il mettre les ipw2200
?).

je vous mets tout ce qui se passe dans l'ordre :
(le eth2 vient d'etre mis en place car on vient de me preter une carte
pcmcia cisco mais j'obtiens /exactement/ les mm symptomes...)

utopia zork # iwconfig eth2 essid "Wireless"  key Ma_Clé
utopia zork # /etc/init.d/net.eth2 start
* Starting eth2
*   Configuring wireless network for eth2
*   Couldn't associate with any access points on eth2
*   Failed to configure wireless for eth2

                        [ !! ]
utopia zork # cat /etc/conf.d/net
#### ECOLE #####

config_eth0=("172.16.103.95 netmask 255.255.255.0")
routes_eth0=("default gw 172.16.103.1")

#iface_eth1="dhcp"
dhcpcd_eth2="-t 15"

Toutefois, j'ai bien la liste des AP disponibles... sauf sur la carte
cisco car ca l'a coupé (c'est certainement normale...)
