Introduction
What it is
Basically it’s a device which performs a deauth attack.
You select the clients you want to disconnect from their network and start the attack. As long as the attack is running, the selected devices are unable to connect to their network.

How it works
The 802.11 WiFi protocol contains a so called deauthentication frame. It is used to disconnect clients safely from a wireless network.
Because these packets are unencrypted, you just need the mac address of the WiFi router and of the client device which you want to disconnect from the network. You don’t need to be in the network or know the password, it’s enough to be in its range.
What an ESP8266 is
The ESP8266 is a very cheap micro controller with build in WiFi. It contains a powerfull 160 MHz processor and you can program it with the Arduino IDE. This makes it perfect for this project.
You can buy these chips for under $2 from China!
