Hello Alx,
J'ai procédé à ce que tu m'as indiqué et le résultat de la commande
cat /sys/ module/rtl8723be/parameters/fwlpsest N
Reste à voir maintenant si cela va rentrer dans l'ordre.

Hello Alx,
Je rouvre le post car je subis à nouveau des déconnexions Je suis repassée sur Xubuntu 14.04 LTS (comme sur mon ancien pc) et depuis quelques jours, mon wifi fait de nouveau des siennes, il se coupe et je dois redémarrer le pc pour pouvoir surfer via wifi.
Précédemment, ton post m'avait aidée à récupérer le wifi donc je suis venue revoir les manipulations à effectuer mais je pense que je me suis un peu perdue 
J'ai lancé
sudo rmmod rtl8723be && sudo modprobe rtl8723be fwlps=0puis
sudo rmmod rtl8723be && sudo modprobe rtl8723be swenc=1 fwlps=0et je voulais vérifier le statut en lançant la commande suivante mais j'obtiens une erreur
jess@Leno:~$ cat /sys/ module/rtl8723be/parameters/fwlps
cat: /sys/: est un dossier
cat: module/rtl8723be/parameters/fwlps: Aucun fichier ou dossier de ce type
jess@Leno:~$ J'ai planté le bazar? 
Merci
Xubuntu 16.04 LTS - Lenovo Z 50 - 64 bits
