How to run a WiFi hot spot from Ubuntu 16.04?

Question

I have installed Ubuntu 16.04 LTS but I am unable to start the WiFi hot spot feature from the network settings. After turning the hotspot, the dialog box confirms the WiFi hot spot is turned on, but the connection does not appear on my phone and other wireless devices.

I use the Internet from an Ethernet LAN connection and want to share my internet connection to other wireless devices.
