Déconnection wifi intempestive
Bonsoir,
J'ai un nouveau pc HP avec windows 8, et j'ai installé ubuntu. J'ai des problèmes pour capter le réseau : l’icône wifi varie de deux à cinq traits, avec de grosses pertes de débit. Dans les pilotes additionnels, un pilote propriétaire est installé. J'ai tenté plusieurs manipulations pour des problèmes similaires trouvés sur le forum avec la carte Broadcom BCM 43142...
Merci par avance

Re : Déconnection wifi intempestive
Bon j'ai attendu quelques jours voir si y'avait du changement mais la freebox n'est pas sous windows donc toujours pareil...
On a deux pc sous windows/ubuntu, l'un à coté de l'autre, l'un est régulier pour ce qui est de capter le wifi alors que l'autre à de grosses pertes et il capte beaucoup moins que sous windows...
