Acer Inspire 7736zg pas de connexion wifi
Bonjour,
Sur un portable Acer Inspire 7736zg, la connexion wifi ne se fait pas. Pourtant je capte le signal, entre la bonne clé WPA mais la connexion n'aboutit pas. En revanche la connexion filaire pas de souci.
Sous Window$7, la connexion wifi se fait sans aucun problème.
Voici les retours des commandes listées dans les consignes.
Merci
