Connexion wifi defectueuse sous Ubuntu 12.04

Bonjour. J'ai migré de la version 11.04 à la version 12.04 d'Ubuntu mais depuis cette mise à jour la connexion à Internet via la wifi est défectueuse. Comment dois-je procéder pour résoudre ce problème car en parcourant ce forum, j'ai remarqué que je n'étais pas le seul à avoir ce problème, mais qu'ils étaient plus ou moins complexes. C'est peut-être dû à ma carte wifi qui n'est pas très performante...

Merci d'avance

Re : Connexion wifi defectueuse sous Ubuntu 12.04

j'ai essayé toutes les commandes qui ont l'air d'avoir bien fonctionné et redémarré le pc, mais l'internet wifi ne fonctionne toujours pas : la page se charge partiellement durant un court instant et puis plus rien. Je crois que mon problème est très sérieux.

Re : Connexion wifi defectueuse sous Ubuntu 12.04

salut
essayes cette manip si ce nest dejà fait

sudo rmmod ath9k
sudo modprobe ath9k nohwcrypt=1

si le wifi fonctionne normalement,fait la manip ci dessous

gksudo gedit /etc/modprobe.d/ath9k.conf

une pages blanche s'ouvres,ecris la ligne suivante:
options ath9k nohwcrypt=1

enregistres et quittes gedit

si toujours rien,redemarres la box en la debranchant electriquement
si toujours rien,change de canal wifi dans les parametres de la freebox,en mettant le canal 7 par exemple,il faut redemarrer la freebox pour que les
changements soient pris en compte

Génial, et merci beaucoup de ton aide.
