*RESOLU* Os Ubuntu 12.04 freeze lors tentative connection Wifi
Bonjour à tous.
Voulant un portable sans OS en vue d'installer Ubuntu, j'ai acheter un Acer Aspire 7250 (je sais, première erreur :-) ), Linpus pré installé.
Dès le premier démarrage, j'ai shunté Linpus et tenté d'installer directement Ubuntu avec CD commandé sur la boutique ubuntu.fr.
Installation se passe sans souci.
Une fois sur le bureau, le logiciel détecte une connexion wireless et ouvre boite de dialogue d'authentification pour le réseau sans fil. J'entre la clé ...WEP... c'est un réseau secondaire CPL DEVOLO, bouton "se connecté" et c'est le plantage...
En entrant les données dans "modification des connexions c'est pire car la clé WEP, une fois enregistrée, la connexion WiFi démarre automatiquement à l'ouverture du bureau et le PC plante sans que je puisse avoir accès à quoi que ce soit et c'est la réinstallation assurée (pour un novice comme moi !).
J'ai un autre portable obsolète sous ubuntu 10.04 hyper stable depuis un moment, j'aimerais bien arriver au même résultat avec celui-ci !
Je précise que je ne maîtrise pas Linux (mais je ne désespère pas de m'y mettre, la preuve :-)
Merci pour votre attention.
