Start Ad-hoc Network To Share Internet and Files

There are two modes of networking; infrastructure mode and ad hoc mode. In infrastructure mode, we use a central device like router or Access Point to connect all devices. This central device share Internet and files among devices connected to it. If you establish a direct connection between two devices without a router or AP, it is called an ad hoc network. In ad hoc mode, we can share the Internet and data between computers. That means in an AD-Hoc network, there is no base station to control and coordinate the packet flow. Here packets are flowing from one computer to another directly and can be compared with walkie-talkies because participating devices communicate directly with each other without any third party devices.

Create Ad hoc Network
