7. From this link: https://ubuntuforums.org/archive/index. ... 30805.html I follow these steps :
But not luck !But so far the driver needs to be installed additionally, module name is 8723bu:
sudo apt-get install --reinstall git build-essential linux-headers-generic linux-headers-$(uname -r)
git clone https://github.com/lwfinger/rtl8723bu
cd rtl8723bu
make
sudo make install
sudo modprobe -v 8723bu
Do not remove the driver folder, it needs to be recompiled after a kernel upgrade via
cd rtl8723bu
make clean
make
sudo make uninstall
sudo make install
Driver info:
