Problème de réseau - ethernet + wifi sur aspire 5749

[Sebsheep]

Bonjour,

Je viens d'installer une Debian Squeeze sur mon nouveau Acer Aspire 5749 et je rencontre des problèmes de réseau :
*Ethernet (!!) : j'arrive à me connecter au début, puis après quelques minutes d'utilisation, la connexion meurt, impossible de la réactiver (en tout cas via l'interface graphique, je ne connais pas de commandes pour ça). La seule solution que j'ai est de rebooter. Et je rencontre à nouveau le même problème.

* Wifi : je n'arrive pas à l'activer. J'ai suivi les instructions sur : wiki.debian.org/iwlagn mais ça ne fonctionne pas (iwconfig retourne : "x no wireless extension" pour x dans "lo","eth0","pan0").

Quelqu'un a des solutions ?

Quelques résultats de commandes :

Bonjour,
je peux répondre à une partie seulement de tes questions:

pour une application graphique il y a le package wicd

ou bien pour il faut éditer le fichier /etc/network/interfaces :

j'ai aussi installé le package wpasupplicant évidement.

On peut aussi utiliser le fichier /etc/wpa_supplicant.conf
si on a plusieurs connexions wifi.

Il y a beaucoup de tutos sur la toile sur ce sujet.

Bon courage.

[Lætitia]

salut,
si le module qui pilote ta carte était bien installé, on le verrait dans "lsmod".
Retour de

Code :

lsmod |grep iwl

Code :

aptitude search iwl

Code :

cat /etc/apt/sources.list

Pour réactiver la connexion filaire, si c'est bien "eth0"

Code :

sudo ifdown eth0

Code :

sudo ifup eth0

Bon courage, @+
