carte wifi disparu ubuntu 7.10

[yanock]

voila mon probleme, j'ai pas pas mal bosser pour activer mon wifi car j'en ai besoin au travail.
J'en ai conclu que le probleme venait de l'activation avec le bouton, je suis sur un amilo 1650g, maintenant la diode est allumé mais je n'ai plus d'interface wifi.

il me semble que ma carte est une atheros ar5005g avec un chipset ar 2413.
Si quelqu'un voit ce que je dois faire merci de me le faire savoir
