connexion wifi

acke · Le 20/07/2008, à 17:08

Bonjour
Je me suis acheté, il y a plusieurs mois, un Dell Inspiron 1720 pour y installer Ubuntu 7.10.
Je n'ai pas pu activer ma Wifi, malgré les tutos et l'aide reçu. Las, j'ai fini par acheter une clé Wifi D-Link qui fonctionne, mais se déconnecte régulièrement pour se reconnecter automatiquement. C'est génant.
Aussi, je suis cette fois fermement décidé à installer ma wifi. Mais comment faire ?
Dans la rubrique, à lire avant de poster, j'ai exécuté les commandes indiquées. En voici les résultats :
