Wifi problems with rtl8723be

Run the following command in terminal

echo "options rtl8723be fwlps=N ips=N" | sudo tee /etc/modprobe.d/rtl8723be.conf
as this will disable some of the power management of the card and usually helps.

And then you need to reboot or manually reload the driver

sudo modprobe -rv rtl8723be
sudo modprobe -v rtl8723be
