There is a Wi-Fi protocol called 802.11 which act as a deauthentication frame. While a Deauther sends packets to interfere with your Wi-Fi signals thus disrupting the normal working of your Wi-Fi router. A Jammer sends noise signals to the Wi-Fi spectrum (2.4GHz) thus disturbing original Wi-Fi frequency spectrum. There is a small difference between these. Technically, we are not making a jammer but a Deauther. But here we are creating our own Wi-Fi jammer. Even ESPs are being sold, with all the software flashed on them for doing these tricks, you just need to Plug and Play. ESP is very popular for Wi-Fi tricks like creating a fake Wi-Fi network, serving your own page to steals someone’s password, block the Wi-Fi network etc. If you are new to this small but powerful chip, then go through Getting started with ESP12 article. This can be done with a tiny Microcontroller ESP12E, which is also referred as Wi-Fi module or NodeMCU. Have you ever thought about jamming the Wi-Fi connection network? Now days Wi-Fi password hacking is very common, so by jamming the Wi-Fi network you can block or jam any Wi-Fi connection, and no one is able to connect to that Wi-Fi network even after knowing the password.
