Create Wi-Fi Hotspot

Creating your own Wi-Fi Hotspot is extremely useful at times, especially for people who travel a lot. Ethernet (wired internet) source and a Wireless adapter connected computer can be converted to a Wi-Fi hotspot so that the mobile devices can access this hotspot, thus sharing the internet. This tutorial will guide you on how to create a wireless hotspot (also called as Wi-Fi tethering) without installing a third-party software. We shall use the elementary OS built in Network connections tool and configure its infrastructure to make Wireless tethering possible.
