Carte wifi ASUS Atheros non détectée Ubun8.04

Bonjour,

Je viens d'installer Ubuntu 8.04 en dual boot avec Windows 7 sur un ASUS portable. Sous 7 le wifi est détecté, notamment en activant grâce à la touche bleue "Fn" puis F2 (avec une antenne wifi dessus). Jusque là c'est classique, une DEL indique le bon fonctionnement du wifi.

Seulement je n'arrive pas à activer cette DEL en particulier et aucun réseau wifi n'est détecté par Ubuntu.

Voici les résultats de quelques commandes qui pourraient donner à des internautes et Linuxiens mieux avertis que moi la source ou la cause du problème:
