bonjour je suis nouveau avec ubuntu 14.04 et j'ai un problème de wifi... je m'explique , j'ai installé ubuntu et fait tout les mise à jour pendant l’installation, avec réseau filiaire. Mais le wifi fonctionne pas . Le voyant et toujours bleu même si j'ai pas de réseau...... Alors j'ai peser dessus pendant 30 seconde et hop les réseaux sont apparu ?? .. ensuite j'ai entrée le mot passe pour mon wifi ... et là il tente de se connecter puis après un certain temps il arrête... sans se connecter....
J'ai rebooter l'ordi ... et encore une fois pas de wifi ...je repère donc sur le bouton wifi et hop ... les réseaux réapparaisse ... vraiment bizarre ... pouvez vous m'aider ... 😉 svp .. merci
Je ne connais pas bcp les commande mais voici ce que j'ai réussi à faire ...
