I have searched for solution to this problem on stack exchange. I do not find WiFi option in the top right corner, neither in the system setting.
I tried installing the driver from GitHub using make
, sudo make install
, sudo modprobe rtl8723be
. They work all right and the repository in cloned onto my desktop. However, on running sudo modprobe rtl8723be
modprobe: ERROR: could not insert 'rtl8723be': Required key not available
sudo service network-manager start
