J'ai installé Ubuntu 15.04 sur mon ordinateur portable avec la carte Wi-fi RTL8723BE. Mais il se déconnecte toujours du réseau. J'ai essayé echo "options rtl8723be fwlps=N ips=N" | sudo tee /etc/modprobe.d/rtl8723be.conf
mais ça n'a pas aidé. Que puis-je faire pour empêcher le wifi de se déconnecter ? Si je passe au noyau 4.X, est-ce que cela aidera ?
