[xubuntu 14.04][RTL8723BE] Interruptions wifi

Bonjour,

Je travaille sur Ubuntu depuis environ 3 ans.
J'ai changé d'ordinateur portable cette semaine et suis passé sur un HP 350 G2 sur lequel j'ai installé xubuntu 14.04.
A part ce problème de wifi, tout semble fonctionner correctement.

Le problème en question :
Lorsque l'ordinateur démarre sur xubuntu le wifi fonctionne normalement. Mais après quelques minutes (en général 5-10) la connexion ne passe plus, sachant que l'icône de wifi indique toujours que celui-ci est connecté.

Les manipulations déjà tentées :
- installation de linux-firmware-nonfree
- désactivation du bluetooth pour éviter un conflit
- D'après https://forum.ubuntu-fr.org/viewtopic.php?id=1550761 #15, j'ai tenté de désactiver le mode n:
echo "options iwlmvm power_scheme=1" | sudo tee /etc/modprobe.d/iwlmvm.conf
echo "options iwlwifi bt_coex_active=N swcrypto=1 11n_disable=1" | sudo tee /etc/modprobe.d/iwlwifi.conf

Tout cela n'a rien changé et je ne vois pas quoi tenter d'autre...

Re : [xubuntu 14.04][RTL8723BE] Interruptions wifi

Après quelques recherches supplémentaires, il semblerait que cela pourrait être lié au driver de la carte wifi RTL8723BE:

D'après http://ubuntuforums.org/showthread.php?t=2220933 #2

Eklipze1229 a écrit :

Sorry for the late response, but I may have a fix. Make a file:

$ sudo gedit /etc/modprobe.d/rtl8723be.conf

When the terminal window opens, copy paste this in:

#Prevents the WiFi card from automatically sleeping and halting connection
options rtl8723be fwlps=0 swlps=0

Tell me how it works. The drivers for this card are horrid at best, I'm trying to find a good replacement. The above fix works for me during browsing, but I lose connection a lot during gaming. At least it's better.

Donc :

- Créer fichier

sudo gedit /etc/modprobe.d/rtl8723be.conf

- Écrire

options rtl8723be fwlps=0 swlps=0

- Sauvegarder et redémarrer

On verra si ça fonctionne.

C'est un problème de la carte wifi à priori, je rencontrais les mêmes problèmes sous win 8.1 avant de passer sus ubuntu et de trouver cette solution ...

Re : [xubuntu 14.04][RTL8723BE] Interruptions wifi

Le problème est réapparu...

De nouvelles recherches:
D'après http://ubuntuforums.org/showthread.php?t=2262957 #2

Pilot6 a écrit :

You need to intall new driver.

sudo apt-get install linux-headers-generic build-essential git
git clone https://github.com/lwfinger/rtlwifi_new.git
cd rtlwifi_new
make
sudo make install
sudo reboot

Donc pour installer les derniers drivers de la carte wifi:

sudo apt-get install linux-headers-generic build-essential git
git clone https://github.com/lwfinger/rtlwifi_new.git
cd rtlwifi_new
make
sudo make install
sudo reboot

Je confirmerai si ça fonctionne.

Re : [xubuntu 14.04][RTL8723BE] Interruptions wifi

Bonjour,
peux-tu confirmer si cela fonctionnait? J'ai le même problème avec la même carte WIFI sur mon toshiba satellite, en ubuntu 14.10.
Mais je n'ai pas l'impression que l'internet coupe complètement: il ralenti et refuse les transferts plus lourd (impossible de regarder plus de 1 min de video en ligne sans coupure interminable, temps d'attende de plus en plus long pour les recherches, ...)
En général, quand je reclique sur mon réseau dans network-manager ça fonctionne  à nouveau normalement quelques minutes...jusqu'au moment ou ça coupe complètement.
Merci pour ton post en tout cas!
N.
