Wifi ne fonctionne plus après quelques minutes sur Acer Aspire E5-771G

Bonjour,
Après un temps plus ou moins long, le Wifi ne fonctionne plus mais j'ai toutes les barres. Par contre, si je désactive pour réactiver (ou si je sors de veille), ça cherche mais ça ne trouve rien.

Voici les infos que j'ai récupérées sur mon PC :

Re : Wifi ne fonctionne plus après quelques minutes sur Acer Aspire E5-771G

Au cas ou te manquerait un pilote, essaie un

sudo apt-get install linux-firmware-nonfree

Redémarre et dis nous si ton problème persiste.

Re : Wifi ne fonctionne plus après quelques minutes sur Acer Aspire E5-771G

J'ai trouvé une solution qui fonctionne pour l'instant. En fait, c'est la carte Realteck RTL8723BE qui se met en veille toute seule. Donc pour la maintenir active, il faut créer un fichier :

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

et dedans il faut mettre les lignes suivantes :

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

Pour l'instant, la carte ne se met plus en veille tout seul !
