"recherche de l'hôte..."
Bonjour à chacun.
J'ai cherché partout mais ne trouve pas de réponse à mon pb:
HP Pavilion 17 notebook, 4core AMD A8-4500M APU with Radeon(tm) HD Graphics, 64bits, Ubuntu 14.10
Mon pb est le suivant:
Je suis connecté en Wi-Fi, et cela fonctionne en général bien. Sauf que, parfois, la connexion ne se fait pas, l'ordi m'indiquant "recherche de l'hôte..." ou "en attente de ...",
et aboutit presque toujours à un dépassement de temps.
Si, au cours de l'attente, je coupe la connexion puis la remets en service, elle se fait immédiatement.
J'ajoute que d'une part ce pb n'arrive QUE pendant la connexion, je n'ai jamais de coupure intempestive, et que d'autre part un autre ordi fonctionnant sous windows n'a jamais ce pb.
Merci de votre aide
