The command sudo modprobe -rv rtl8723be removed the module from the running kernel (that's what the -r option does - it's short for --remove).
This doesn't alter any configuration, so the driver will be inserted again on the next boot. To insert it manually, run sudo modprobe rtl8723be (without the -r option). You don't need the -v option; it only makes the command's output more verbose. Also see man modprobe for more information.
