Problème récurent de wifi aléatoire suite à 9.10
Bonjour,
Presqu'à chaque démarage de mon ordi depuis la mise à jour, le wifi bugge, j'entends par là que mon ordi reconnait la clé, mais que visiblement, la clé ne trouve aucun réseau.
Je débranche, rebranche, cette clé jusqu'à avoir une connection. Aussi, parfois j'ai une bonne connection mais elle se coupe en plein milieu pour devenir trrrèèèèès lente 
.
J'en ai un peu marre, quelqu'un aurait-il une solution?

Re : Problème récurent de wifi aléatoire suite à 9.10
Salut
J'ai eu le même problème (en pire) plus bien d'autres...
Du coup j'ai carrement downgradé vers Jaunty aprés 1 mois à batailler avec la config de Karmic.
Ok la solution est radicale mais la difference entre les deux distros ne justifie pas à mes yeux de se faire autant ch***.
Au cas ou je détaille la procédure içi : http://forum.ubuntu-fr.org/viewtopic.php?id=363382

Pensez à passer en RÉSOLU...(en éditant le titre du 1er message)
