When you are connected to the wireless network, it sends packets to you and then your computer converts these information to websites, movies, images… Imagine that two computers are connected to the wireless network, first computer wants website google.

Open VirtualBox, start kali virtual machine and open terminal. We need to stop our wireless card to change the MAC address. The ifconfig is a program, wlan0 is our wireless card and the down is action what we want to do.
