bonjour la communauté je m'appelle david et je suis nouveau sur ubuntu.

je suis en possession d'un dell inspiron 1720 et je fonctionne sur 11.10 32 bit.

j'ai actuellement un problème avec le wifi étant donné qu'il ne scanne aucun réseau. j'ai déja regardé ce qu'on pouvait faire sur internet, mais mes tentatives se sont montrées infructueuses... à la liste de manips à faire avant de poster j'ai ceci:
