Bonjour à tous.
De retour de 5 jours d’absence, j’ai mis à jour (aptitude safe-upgrade) ce matin et, depuis (coincidence ?) le passage à KDE 4.3, plus de wifi.
Je dois passer par [quote]ifconfig wlan0 up[/quote] pour que les diodes de ma carte PCMCIA s’allument et KNetworkmanager ne me propose qu’une interface en eth0.
Avant cette maj, aucun pb de wifi.
Quelques renseignements :

Quelqu’un aurait-il une piste ?
Merci d’avance !
