Triste Wifi (Realtek 8723be sur 15.04)
Bonjour,
La wifi sur mon Lenovo z50 n'a jamais été brillante (du moins sur Ubuntu ; sur le Windows 8 installé en parallèle, ça marche très bien), mais au moins, suite à des manipulations trouvées ça et là et notamment le pilote proposé par lwfinger, je n'ai plus de déconnections aléatoires.
Néanmoins, depuis quelques temps, la qualité a franchement diminué, le débit est au mieux au quart de celui obtenu sous Windows ou par connections câblée, et ça vient par brefs à-coups après des pauses de plusieurs secondes, exceptionnellement plusieurs minutes, le problème augmentant avec la durée d'utilisation.
J'en suis quelque peu las.
Pourriez-vous aider mon cas désespéré, s'il vous plaît ?
Et pour pas être chiant, on va faire comme on a dit, voici les infos demandées.

Re : Triste Wifi (Realtek 8723be sur 15.04)
Je te remercie, mais les problèmes de déconnections réglés par la manœuvre liée avaient déjà été résolus. Maintenant, mon problème est que j'ai certes une connexion qui reste, mais qui reste naze.
Néanmoins, merci de ton attention.

Lis la discussion depuis la première page, l'option qui m'a sauvé n'est peut-être pas celle qui va te sauver.
Maintenant, je pense que ton problème est similaire à celui que j'ai rencontré.

Re : Triste Wifi (Realtek 8723be sur 15.04)
Quand tu lances cette commande:
sudo rmmod rtl8723be && sudo modprobe rtl8723be fwlps=0Que se passe-t-il?

Déconnexion de la wifi, reconnexion immédiate, et le débit est encore plus bas que juste avant.

Re : Triste Wifi (Realtek 8723be sur 15.04)
Lance deux fois la commande:
sudo rmmod rtl8723be && sudo modprobe rtl8723be fwlps=0Puis dis-nous ce qu'il se passe.
