Bonsoir,

Je sèche depuis le début de l'après-midi sur un problème : je n'arrive pas à configurer correctement l'outil réseau pour avoir une connexion sans-fil à Internet.
J'ai installé les outils Airport (le PowerBook est équipé d'une Airport Extreme, norme 802.11 g), mais je ne crois pas qu'on puisse en tirer grand chose (ils datent de 2001 et 2003).

Je sais que le noyau de Linux (supérieur ou égal au 2.6.18) intégré dans la dernière version stable de la Debian intègre déjà le pilote Broadcom 4318 (bcm43xx-fwcutter). Quoi que... Les rsultats de dmesg | grep bcm43xx dans le Terminal montrent que c'est loin d'être évident... Toujours est-il qu'il n'y a pas moyen de l'activer pour qu'il fasse son boulot.

Je vous donne quelques résultats de commandes lancées sur le Terminal en root :
