Abstract - With the growing dependence on wireless communication, Wi-Fi networks are increasingly targeted by various forms of cyberattacks, notably jamming attacks that disrupt connectivity and degrade service availability. Among these, deauthentication attacks are commonly used to launch denial-of-service (DoS) operations by exploiting inherent vulnerabilities in the IEEE 802.11 protocol. This paper presents a low-cost, efficient, and real-time system for the detection and classification of Wi-Fi jamming packets using the ESP8266-based NodeMCU platform. Deauthentication attacks are filtered and classified using a lightweight algorithm implemented via the Arduino IDE, while alert mechanisms are integrated through LEDs and serial output.This work contributes toward accessible and scalable network security solutions through embedded systems.
