Traditionally, wired LAN networks were used to transfer data between multiple computers and these days, it has become wireless. However, wireless networks usually require internet connection to send data between multiple computers.

Connecting two computers wirelessly, for transferring data, without having a Wi-Fi router in between seems quite difficult because you may have not heard about such means of data sharing. However, just because you have not heard it before does not mean that it is not possible.

Students in computer labs, both with instructor and without.

One can still send data through airwaves without connecting to internet through the Windows built-in function Ad Hoc Network which gives the user freedome to connect two computers with each other wirelessly and even without a Wi-Fi router or switch in between them.

The only component that both the users will require, to make the most of this feature, is the wireless card installed in their system which, in case of laptops, are already built-in. However, if you are trying to connect two desktop PCs, you will need to attach a USB Wireless Adapter to create a wireless connection.

Given below are the steps that you will need to carry out in order to create a wireless connection between two computers without any internet connection.
