Déconnexions régulières du wifi

Bonjour à tous,

J'ai converti ma soeur au logiciel libre et je suis arrivé à lui installer Ubuntu. Seulement, il y a de gros problèmes de wifi sur son ordi (déconnexion régulières, ca capte mal...).

Pouvez-vous m'aider ?

Je vous met le résultat des commandes demandées, elle est sous Hardy.
