How To Install Open-Wrt Firmware In TP-Link Router Model 740N

Before start the whole installation process, we must know about the Open-Wrt firmware.

OpenWrt is a project which targets Linux operating system based embedded devices.It provides multiple types of firmware for networking devices which is fully customizable. Instead of trying to create a single, static firmware, OpenWrt provides a fully writable filesystem with package management.

This frees you from the application selection and configuration provided by the vendor and allows you to customize the device through the use of packages to suit any application.
