Pourtant ce matin et depuis les 4 semaine que j'utilise ubuntu 14.04.1, le wifi marchais bien.
Ses quand j'ai voulue ajouté une nouvelle connexion wifi livebox d'un amis qui m’hébergeais pour les vacances que tout a planté.
J'ai essayé de supprimé les connexions existantes pour les rajoutés, mais plus moyens de faire marché le wifi.

une solution?

bonsoir,
retour stp de

cat /etc/network/interfaces

quel est ta livebox dans celle listé au dessus ?

denisalb · Le 28/08/2014, à 03:47

Ma livebox play et Livebox-3258
et livebox-3258-ext ses mon répétiteur wifi quand je suis a l'étage
Sinon pour la commande: cat /etc/network/interfaces dans un terminal, elle me retourne rien du tout.
J'ai dans le terminal:

denis@denis-Aspire-E1-771G:~$ cat /etc/network/interfaces

Je me permet de faire un petit up, car il et de plus en plus urgent que je retrouve le wifi sur mon ordinateur merci

toutafai · Le 29/08/2014, à 00:20

remettre le fichier interfaces comme il doit etre avec cette commande

echo -e 'auto lo\niface lo inet loopback\n' | sudo tee /etc/network/interfaces

rebooter et tester, si toujours pas mieux changer le chiffrement a probleme actuel sur ta box, pour soit que du wpa1 TKIP, soit que du wpa2 AES (pas les 2 en meme tempsn ne pas oublier d'enregistrer les changement sur la box et de la rebooter)

denisalb · Le 29/08/2014, à 04:56

Merci en passant en wpa2 sa a marché mais je comprend pas pourquoi sa fonctionnais bien depuis juillet.
