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

sudo iwconfig wlan0 power off

sudo ifconfig wlan0 down

sudo ifconfig wlan0 up

si ça fonctionne

gksudo gedit /etc/pm/power.d/wireless

une page blanche s'ouvres,ajoutes ces 2 lignes

#!/bin/sh
/sbin/iwconfig wlan0 power off

enregistre le fichier et quittes gedit
puis rendre le script executable au demarrage

sudo chmod +x /etc/pm/power.d/wireless

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

Salut,

J'ai testé tes commandes et maintenant le wifi fonctionne correctement, même après un redémarrage.

Génial, et merci beaucoup de ton aide.
