Knetworkmanager ne veut plus me connecter au wifi

JenHob · Le 13/01/2008, à 19:06

Ma connexion sans fil marchait tt a fait normalement... jusqu'au moment ou...

J'ai eu la bonne idee de cliquer sur configuration manuelle en dessous de mon habituelle liste de reseaux sans fil, et de cocher la petite case demandant permettant de creer une adresse IP via le protocole DHCP (je comprend pas la moitie de ce que je raconte, mais ca semblait correspondre aux configurations mise dans le routeur).
Depuis lors (c'etait hier) knetworkmanager ne me montre plus la liste de reseaux wifi disponibles

pour l'instant j'ai reussi a me connecter en utilisant un cd de demarrage ubuntu (d'ou la complete absence d'accent...) mais tant qu'a faire si je pouvai eviter de tout devoir reinstaller :-S

voici ttes le infos necessaires...
