Bonjour,
J'ai installé Ubuntu en dual boot il y a peu en m'aidant des diverses discussions sur ce forum. Cependant le Wifi se déconnecte régulièrement sans que je le veuille, notamment lors de gros téléchargements. J'ai trouvé plusieurs discussions à ce propos, mais je n'ai pas réussi à résoudre le problème, malgré plusieurs solutions essayées. Je viens donc vous demander votre aide, ne m'y connaissant pas vraiment !
Voici les informations demandées (j'espère que c'est bien ça !) :
