connexion internet impossible malgré une carte wifi reconnue
Bonjour à tous,
J'avais posté autrefois un sujet concernant un problème proche qui semblait résolu mais après un arrêt assez long d'utilisation du PC et du réseau, de nouveau voilà que cela cloche pas mal.
J'ai repris pas mal des commandes qu'on m'avait demandé :

Re : connexion internet impossible malgré une carte wifi reconnue
Pour une connexion avec l'applet Network-manager
modif du fichier interfaces
echo -e 'auto lo\niface lo inet loopback\n' | sudo tee /etc/network/interfaceset connecte toi avec network-manager (2 tv en haut a droite à coté de l'heure)!
Ca donnes ça N-M
