Wifi accessible uniquement après branchement ethernet

Support Debian
#1

Bonjour,

J’ai décidé il y a peu de me tourner vers Debian. Sur ubuntu depuis un moment j’ai décidé de passer le cap.

Après une sauvegarde de mes fichiers de configuration sous ubuntu, j’ai donc installé une testing dans un premier temps mais impossible de me connecter durant l’installation, le programme se bloquait à l’installation de grub. J’ai donc tenté une installation d’un système linux mint dérivé de debian.

Mais là impossible de me connecter aussi en wifi. J’ai donc regardé le fichier /etc/network/interfaces par rapport à celui sauvegarder de ma configuration précédente mais ce sont les mêmes.

Ma carte wifi ne détecte aucun réseau (même avec iwlist scan)

J’ai alors tenté de me connecter en ethernet sous mint et là miracle : il trouve les réseaux wifi. Je ne comprend pas bien d’où ça peut venir.

Salut

tu utilises quoi comme gestionnaire de connexion : Network-manager, wicd, … ?

Si tu n’as pas de gestionnaire de connexion réseau
tu peux ajouter dans /etc/network/interface :

auto wlan0 iface wlan0 inet dhcp wireless-essid crous-poitiers
Je suppose que le wifi est ouvert

Merci de ta réponse

J’utilise network manager. Sute à un deuxième redémarrage finalement l’access point est bien déterminé automatiquement mais je dois relancer

au démarrage sinon je n’ai toujours aucun réseaux.

Désolé de mon ignorance mais est ce que c’est normal ?

Edit : Euh non problème non résolu en fait. Je ne sais pas pourquoi après redémarrage je n’ai plus de réseaux wifi encore une fois et sudo modprobe -r acer-wmi ne donne plus de résultat :confused:

This file contains the names of kernel modules that should be loaded

J’ai tenté de rajouté ath5k dans /etc/modules mais rien n’y fait, toujours aucune connexion de disponible en wifi avant de me connecter en ethernet.

Bien remarqué mais 00:15:C7:A9:E2:E0 (resp 00:15:c7:aa:40:00, etc) sont les adresses mac des points d’accès.

Essaye à la main en faisant

ifconfig wlan0 up

iwconfig wlan0 essid crous-poitiers

iwconfig wlan0 ap 00:15:C7:A9:E2:E0

puis tu lances wpa_supplicant

Il y a peut être un bazar entre deux points d’accès identiquement proches sur le même réseau.

J’ai essayé mais ça ne donne malheureusement toujours rien. Je n’ai toujours pas de réseaux disponibles au démarrage. Obligé de me brancher en ethernet.
J’ai testé un live cd d’ubuntu et il trouve les réseaux avec network manager je ne comprend pas :confused:.

J’obtiens ceci sur le live cd :
