[Résolu] Connexion internet par wifi tres lente et qui tombe...

Salut a tous les amis,

J'ai installer ubuntu 14.04lts a coter de windows, mais j'ai un gros probleme avec internet, car la connexion internet est lente(par rapport a win) et tombe tous les 5 min, c'est a dire que je reçoit "server not found" sur mozilla apres des minutes d'attente.
MAIS je reste toujour connecter au reseau ... c'est vrai que je utilise pas une carte wifi, mais une cle usb wifi, mais je n'est jamais eu ce probleme auparavant avec win...

Un petit exemple, j'ai fait un test sur http://www.speedtest.org/, sur le meme pc, les deux testes a la suite, et avec les memes apareils connecter au meme temps au resau, windows= 20Mb/s ubuntu=0.1Mb/s... donc je suis quasiment sur que le probleme ne vient pas du fournisseur.

J'espere que quelqu'un vas m'aider Merci d'avance

Re : [Résolu] Connexion internet par wifi tres lente et qui tombe...

Bonjour Victor,

J'ai trouvé sur Github (Lien vers l'article original) un pilote corrigeant les problèmes constatés avec ta carte wifi (Ubuntu 13.10 et supérieurs).

Tu peux essayer d'installer ce pilote en suivant ces étapes :

Installation des pré-requis :

sudo apt-get install git linux-headers-generic build-essential dkms

Clonage du dépôt :

git clone https://github.com/pvaret/rtl8192cu-fixes.git

Ajout du module DKMS :

sudo dkms add ./rtl8192cu-fixes

Build et installation :

sudo dkms install 8192cu/1.10

Mise à jour de la liste des modules :

sudo depmod -a

S'assurer que le pilote natif est blacklisté :

sudo cp ./rtl8192cu-fixes/blacklist-native-rtl8192.conf /etc/modprobe.d/

Rédémarrer et c'est fait !
