Ubuntu 16.04 Wifi continue de se déconnecter

J'utilise UBUNTU 16.04. Mon wifi continue de se déconnecter encore et encore !! Le résultat de lspci -knn | grep Net -A2 est:

J'ai ce problème avec l'un de mes ordinateurs portables chaque fois que je fais une installation propre. La carte réseau Realtek ne s’entend pas bien avec Linux.

C'est la méthode que j'utilise pour résoudre ce problème

Dans le terminal, tapez les commandes suivantes:

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 modprobe rtl8723be

Cela me permet toujours de travailler correctement sur la seule machine que j'ai avec un adaptateur Realtek.
