encore un problème de wifi ...
bonjour à tous,
d'après ce que je lis sur le forum depuis quelques jours (voire semaines) le wifi pose un problème à beaucoup d'entre nous, et je n'échappe pas à la règle !
voici mon souçi, après un déménagement de ma freebox v4 qui s'est très bien déroulé je n'arrive plus à me connecter en wifi avec ma ubuntu 9.04.
je m'explique en détail, dans mon autre logement j'étais parfaitement connecté en wifi avec ma freebox en wep.
une fois le déménagement effectué, la ligne remise en route, connection OK dans mon nouveau logement, mais je me suis dit avec tous les méchants hadopistes il serait plus prudent que je passe en WPA ...
configuration du premier pc de ma femme sous XP, OK, deuxième PC le mien en double boot, sous XP OK (oui, je sais c'est pas bien, mais j'ai encore quelques jeux qui ne tournent pas sous wine ..), et ensuite sous UBUNTU, OK en filaire, mais en wifi, alors là ... galère depuis deux semaines !! j'ai essayé de nombreuses solutions trouvées sur ce forum et sur google, mais rien, désespérement rien, avec la pluie qui tombe depuis quelques jours je commence à déprimer grave !
j'ai essayé network manager, network admin, et aussi wicd ... rien !
bon je vous poste toutes les commandes de "l'épinglé":

Re : encore un problème de wifi ...
j'ai oublié de dire que lorsque je tente de me connecter network manager me demande mot mot de passe et il cherche, cherche en vain ... et au bout d'un moment il me le redemande et jamais il ne se connecte ...
