je ne comprends rien

C'est "lspci", pas "ispci".

Avec un L au début (ça veut dire LiSt PCI, autrement dit lister les périphériques PCI, pour savoir ce que tu as comme chipset wifi exactement).

Tu as installé ton pilote Atheros comment? Fais un "dpkg -l | grep madwifi" pour voir si tu as le bon pilote.
