[Résolu] Réseau Wifi non fonctionnel, icone wifi ok

Bonjour,

Je viens d'acheter un Eee PC "Seashell series" R051CX-BLK001U de chez Asus.
La diode qui indique que le wifi est fonctionnel est allumé.

J'ai rentré mes identifiants wifi, puis j'ai vu l'icône wifi s'afficher correctement.

Mais lorsque je lance un navigateur, ou bien la logithèque, impossible de trouver du réseau, alors que l'icône wifi reste allumé (je suis à coté du routeur pour mes tests)

J'ai fais comme test :
- connexion en ethernet : marche nickel (ça m'a permis de mettre mon système à jour)
- connexion via une clé wifi externe qui fonctionne sur un autre PC : problème identique, même symptôme.

J'espère que quelqu'un pourra m'aider sur le forum, le problème ayant l'air d'être purement logiciel.

Je vous liste les commandes demandées, cable ethernet débranché, clé wifi usb débranchée :

Re : [Résolu] Réseau Wifi non fonctionnel, icone wifi ok

Salut,

plusieurs causes possible :
1/ Déjà débranche ton câble ethernet quand tu te connecte en wifi
2/entre cette commande :

echo "options ath9k nohwcrypt=1" | sudo tee -a /etc/modprobe.d/ath9k.conf

redémarre ton pc et test a nouveau ton wifi
3/Ensuite ipv6 qui est configuré et qui peut poser problème : modifie ta connexion wifi, onglet IPv6, mettre sur "ignorer"
4/Le cryptage WEP fait par ta box est parfois mal supporté par du matériel en norme N comme le tiens (changer pour soit sur wpa1 TKIP, soit du WPA2 AES, ne pas oublier d'enregister les changements sur ta box, puis de la rebooter. Enfin refait ta connexion wifi sous ubuntu

Re : [Résolu] Réseau Wifi non fonctionnel, icone wifi ok

de rien, on as juste dit au module (=driver) qui gère ton wifi, qu'il disent a ta carte wifi de ne pas gérer le chiffrement par lui même, mais de laisser faire le module (j'suis pas sur que ce soit clair ce que je dit la)

Pour modifier le titre de ton message, edite ton 1 er message (lien "modifier" en bas de chaque message)
