Configuration wifi sur un PowerBook G4

Support Debian
#1

Bonjour,

Je viens d’installer la Debian Etch sur mon PowerBookG4. Tout a été bien et facilement configuré, sauf la connexion au sans-fil. Je sèche depuis le début de l’après-midi sur ce problème, en essayant différentes procédures trouvées ici ou là.
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 néanmoins quelques résultats de commandes lancées sur le Terminal en root :

Visiblement, le firmware n’est pas installé.

[quote]You need to get bcm43xx-fwcutter and cut the firmware (from the Windows driver) for the device; bcm43xx.berlios.de/

Personally I would rather use ndiswrapper so the wireless runs a full speed and not limited to 11-Mb/s
(…)
Thanks!
I run: bcm43xx-fwcutter -w /lib/firmware /home/user/wl_apsta.o and everything runed smooth:[/quote]

C’est comme cela que je faisais avec un iBook G4 sous etch.

Merci de vos conseils ! Et rapides, en plus…

J’ai fini par réussir à configurer correctement la wifi (après 12 h. d’efforts, quand même, mais finalement, la procédure n’était pas compliquée : il fallait seulement que j’arrive à comprendre comment l’adapter), et ça fonctionne. Effectivement, il y avait un problème de firmware à résoudre. Aussitôt, on me demandait le mot de passe (les Box environnantes étaient détectées…), et hop, c’était parti.

Une question complémentaire : comment faire pour que la connexion soit établie au démarrage de la Debian ? J’ai vu passer qqch là-dessus hier, mais évidemment, je ne l’ai pas noté.

Merci de vos réponses !
