Bonjour à tous,


Je viens d'installer un ubuntu 16.04 (32 bits) sur un de mes vieux PC portable.
Cependant j'ai un problème, je ne vois aucun de mes réseaux WIFI.
Rentrer le réseau WIFI manuellement ne fonctionne pas.
Pouvez-vous m'aider pour résoudre ce problème ?
Ci-joint un descriptif de ma carte :

Salut,

Tu as envoyé beaucoup d'informations inutiles, la prochaine essaies de simplement donner la réf de ta carte Wi-Fi ou le résultat de commandes comme
lspci
ou
ifconfig
s'il te plait !

Pour ton problème, dans un terminal, entres ceci :
sudo modprobe ath5k


Je rencontre le même souci actuellement et je suis contraint d'entrer cette commande à chaque fois que je boot sur Ubuntu (tout marchait correctement, j'ai inséré ma clé Wi-Fi et tout a planté bref).

Si tu veux automatiser le tout, tu peux ouvrir en tant que root le fichier rc.local, qui se trouve normalement ici :
/etc/rc.local

sudo gedit /etc/rc.local

Entres ton mot de passe et ajoutes sudo modprobe ath5k, en prenant bien garde de laisser "exit 0" à la toute fin du fichier.

Si ça ne marche pas c'est que je me suis trompé sur le module à charger.

HF !

EDIT : En fait c'est bizarre puisque c'est le bon module qui est choisi au vu des infos que tu as mises, tiens-moi au courant ça m'intrigue.
