Demande de connexion persistante
Bonjour, j'ai installé Ubuntu 14.04 sur l'ordinateur d'une amie sur lequel persiste un problème vis à vis d'internet.
Lors du démarrage de l'ordinateur la wi-fi fonctionne parfaitement pendant + ou - 1 minute, suite à quoi l'ordinateur demande en boucle le mot de passe de la box sans qu'on puisse faire quoique ce soit sur internet sauf si on connecte le pc en ethernet. De plus ceci ne vient pas de la box car le problème est le même sur d'autres box (Freebox et Livebox).
Si quelqu'un a une piste je veux bien, car j'ai beau fouiller le forum, tester des solutions et le désespoir commence à m'envahir.
Merci d'avance pour vos messages !

Bonjour,
Peux-tu donner le retour, entre balises codes <>, des commandes suivantes, sur l'ordi de ton amie
cat /etc/lsb-releaselsusblspci -nn | grep -i netlspci -ksudo lshw -C networklsmodiwconfigifconfigsudo iwlist scanuname -r -m cat /etc/network/interfacesnm-toolsudo rfkill listLa philosophie nous enseigne à douter de ce qui nous paraît évident. La propagande, au contraire, nous enseigne à accepter pour évident ce dont il serait raisonnable de douter. (Aldous Huxley)
"La plus grande partie de la souffrance humaine est inutile. On se l'inflige à soi-même aussi longtemps que, à son insu, on laisse le mental prendre le contrôle de sa vie". (E. Tolle)
