Carte Wifi détecte les réseaux, mais ne se connecte pas

Nico_Carotte · Février 21, 2016, 6:39pm

En premier lieu BONJOURà tous.

Utilisateur libre depuis quelques années (Mandrake en 2005, puis Ubuntu puis Debian), c’est la première fois que j’ai besoin de demander de l’aide sur un forum à propos de matériel, comme quoi en cherchant bien la documentation des systèmes libres est conséquente, merci à tous pour votre boulot.

Je viens de changer d’ordi pour un portable lenovo SL400.
Pas de soucis d’installation de Debian Wheezy en 64 bits.

Linux PCCAROTTE 3.2.0-4-amd64 #1 SMP Debian 3.2.51-1 x86_64 GNU/Linux

Ma carte Wifi est bien reconnue, la commande $lspci donne

02:00.0 Network controller: Intel Corporation PRO/Wireless 5100 AGN [Shiloh] Network Connection

A partir de là, j’ai suivi les instructions de la page du microcode correspondant (il me semble ): https://wiki.debian.org/iwlwifi.

Au final, network manager détecte bien les réseaux présents, mais quoi que j’y fasse, il ne veut pas se connecter. Pas plus à ma freebox qu’à numericable chez mes parents qu’aux wifi publics.

Et là je sèche, si quelqu’un a une idée , je suis preneur.

Quelques infos en plus?

Bonjour !
Première piste provisoire : essaie en replaçant network-manager par wicd.

docanski2 · Février 21, 2016, 6:39pm

Salut,

Nico Carotte:

Ma carte Wifi est bien reconnue, la commande $lspci donne
A partir de là, j’ai suivi les instructions de la page du microcode correspondant (il me semble ): https://wiki.debian.org/iwlwifi.

Y compris le firmware en suivant ce détail qui a son importance : “Non-free firmware is required, which can be provided by installing the firmware-iwlwifi package.” ?

Nico_Carotte · Février 21, 2016, 6:39pm

Bonjour thuban et Dokanski2

@Dokanski2: non je n’ai pas oublié cette étape pourtant

@thuban: alors j’ai stoppé network-manager, j’installe wicd, je lance wicd puis wicd-client, et là je ne détecte plus les réseaux. La diode du wifi est éteinte et ne veut pas se rallumer ni en passant par wicd, ni par le raccourci clavier (qui fonctionnait avec network-manager). J’ai testé également en virant complètement network-manager, et en relancant wicd, ce n’est pas mieux.

Merci pour les pistes

Essaie de lancer ton network manager depuis une console, il sera plus bavard sur des erreurs ou warning éventuels.
Sinon, désactive tout network manager, et fait une config à la mano en CLI. Tu verras bien si tu as des messages.
Regarde aussi les errors au boot éventuelles avec dmesg (si il ne trouve pas un firmware, c’est là qu’il le dit)

Bonjour Piratebab.

J’ai enfin pris le temps de tester tes propositions, merci de te pencher sur le cas de cette carte récalcitrante. voila le retour de NetworkManager dans la console:

Quant à configurer l’interface en CLI, ça me dépasse encore pour l’instant, j’avais fait divers essais sans succès jusque là, je ne sais pas comment remplir le fichier /etc/network/interfaces, les propositions trouvées sur le net sont diverses et variées, il y a trop de paramètres en jeu pour pouvoir tout tester pour l’instant. (Et puis j’ai mon cable de 30m pour faire comme si c’était un portable )

Mon problème reste entier

piratebab · Février 21, 2016, 6:43pm

je te proposais de configurer en CLI pour justement ne pas toucher au fichier network interface.
Les logs de ton networkmanager semblent dire que coté driver et firmware c’est OK, mais que c’es wpa-supplicant qui met fin à la connexion.
Fait quand même voir ton fichier interfaces.
Et regarde dans les logs du coté de wpa-supplicant.
