problème WIFI sous kubuntu 9.04

Bonjour à tous,

Comme beaucoup d'entre-vous j'ai, depuis la mise à jour 9.04, un problème de Wifi. Celui-ci marchait très bien sous Kubuntu 8.10 et depuis grand désespoir !!

Je pense être près de la solution mais cela ne marche toujours pas voila les résultats des différentes commandes :

Re : problème WIFI sous kubuntu 9.04

Bonjour à tous

Ca y est le wifi est revenu !!
En finissant par me relier en ethernet j'ai découvert que ma livebox était en protection WPA-PSK et donc qu'il fallait adapter /etc/network/interfaces en wpa (voir la page wifi -wpa dans la documentation)

Merci quand meme
