[Résolu] Problème Wifi

Bonjour à tous,

Je viens d'installer Ubuntu 8.02 sur mon portable qui est un Acer Aspire 5715Z, et je n'arrive pas à configurer le wifi...Quelqu'un pourrait me dire par quoi commencer pour bien faire.

Merci d'avance !

Bonjour,

06:00.0 Ethernet controller: Atheros Communications Inc. AR242x 802.11abg Wireless PCI Express Adapter (rev 01)

Voir cette page de la Documentation http://doc.ubuntu-fr.org/atheros_ar5007eg

Résumé :

Pré-requis généraux

      Disposer des droits d'administration, ceci pour installer les pilotes.
      Disposer d'une connexion à Internet configurée et activée (ou un moyen de récupérer les pilotes).

Pour compiler :

      Recharger la liste des paquets, puis installer le paquet :

sudo apt-get install build-essential

Puis :
(vu la version actuelle, remplacer cd madwifi-hal-0.10.5.6-* par cd madwifi-hal-0.10.5.6-r3942-20090205)

wget http://snapshots.madwifi-project.org/madwifi-hal-0.10.5.6-current.tar.gz
tar xvzf madwifi-hal-0.10.5.6-current.tar.gz
cd madwifi-hal-0.10.5.6-*
make
sudo make install
sudo modprobe ath_pci

Vérifier que ath_pci est bien dans /etc/modules, sinon ajoutez-le :

echo "ath_pci" | sudo tee -a /etc/modules

Redémarre et tu devrais voir apparaître ton chipset en tant que "ath0" ou "wlan0" avec la commande iwconfig.
Erreur possible :

Si après redémarrage l'interface wlan0 ne fonctionne pas, peut-être faut il blacklister ath5k, afin que ath_pci soit chargé :

echo "blacklist ath5k" | sudo tee -a /etc/modprobe.d/blacklist

En cas de mises à jour du noyau (kernel) le passage suivant est à refaire :

cd madwifi-hal-0.10.5.6-*
make
sudo make install
sudo modprobe ath_pci

A+

Re : [Résolu] Problème Wifi

Merci, après le redémarrage, tout fonctionne correctement !
