Probleme wifi inspiron 9400

Bonsoir,

Depuis que j'ai installé la nouvelle version de kubuntu (8.04), je n'ai plus de wifi. Pourtant, dans la configuration réseau je vois bien mon périphérique réseau sans fils activé :s

J'éspere que ces informations vous seront utiles:

Re : Probleme wifi inspiron 9400

Salut,

j'ai eu le même souci (exactement la même config). Le problème vient de la nouvelle version du noyau linux. Il suffit donc de démarrer avec l'ancienne version du noyau (à priori tu as le choix au démarrage) et ÇA MARCHE!
