A Wi-Fi Disruptor in the Modern Age

Abstract: The rapid development of Wi-Fi enabled devices is important in wireless network security. This research focuses on the design and implementation of a Wi-Fi jammer using NodeMCU (ESP8266) microcontroller that disrupts local Wi-Fi communication by exploiting vulnerabilities in IEEE 802.11 protocol. Jammers work by disrupting devices in the access point area by sending authentication packets. This paper describes the hardware and software of the project, including the configuration of ESP8266, firmware development, and how packet injection works. This study demonstrates the simplicity of manufacturing jamming devices, while also revealing their misuse and the ethics of using these systems. Finally, this work contributes to the broader field of wireless network security by providing insight into potential defenses to mitigate the effects of Wi-Fi network vulnerabilities.
