configuration wifi

Bonjour,
je viens de ré-installer ubuntu intrepid ibex. le réseau wifi n'est pas détecté. J'ai parcouru la doc sans réussir à résoudre mon problème.

Re : configuration wifi

excusez moi, je finis mon message...
ce que j'ai fait jusqu'à maintenant : vu que ma carte était Broadcom Corporation BCM4306 802.11b/g Wireless LAN Controller (rev 02), vu que dans ce cas je pouvais installer le paquet b43-fwcutter. j'ai voulu l'installer. j'ai eu error 1. j'ai vu qu'il y avait ce cas, j'ai suivi la procédure indiquée http://doc.ubuntu-fr.org/wifi_broadcom_bcm43xx
mais dans le terminal j'ai no such files or directory.
désolée, je craque. si vous pensez que je dois chercher encore, dites le moi.

Re : configuration wifi

D'après le résultat de lshw, le pilote de ta carte wifi est b43-pci-bridge, or je ne le vois pas dans la liste des module chargés (lsmod).

Peut-être peux-tu essayer de le charger manuellement ?
Tente : modprobe b43-pci-bridge.
