Problème connexion wifi avec un Lenovo - G50-30

dinoo.fr · Le 04/04/2015, à 18:37

Bonjour à tous,

Je suis un tout nouvel utilisateur de Kubuntu depuis ce matin et je n'arrive pas à me connecter à internet. Le logo wifi est grisé malgré une carte wifi reconnue par kubuntu.

Quelqu'un aurait-il une idée ?

En vous remerciant.

Je crois qu'il manque un petit sudo devant pourfaire

sudo rfkill unblock all

Ce post donne une solution pour ta machine, espérant que ça marchera aussi pour toi.

Aucun résultat..

dinoo.fr · Le 04/04/2015, à 19:35

La ligne de commande n'affiche rien et je peux retaper quelque chose.

Ayral · Le 04/04/2015, à 22:51

Normal qu'elle ne réponde rien.
As tu tapé la ligne indiquée au post # 6 de cette conversation ?
Donc après tu redémarres et tu testes le wifi.
