Pb Wifi - Ubuntu 14.04 - Intel 5100
Bonjour à tous,
J'ai installé Ubuntu 14.04 sur un PC Dell E6410 acheté d'occasion à un professionnel. En théorie la carte WiFi fonctionne puisque le PC a été testé. Depuis l'installation, on peut voir les connexions WiFi disponibles mais impossible de se connecter. Après des heures de recherche j'ai pas tenté grand chose. La seule modification que j'ai laissé est l'ajout du fichier "iwlwifi-5000-1.ucode" (driver supposé pour cette carte WiFi) dans le repertoire "/lib/firmware/".
Voici la réponse de checkwifi :
