Abstract:As Internet of Things (IoT) devices become increasingly common in public environments, ensuring their seamless and secure access to network connectivity is essential. Public and guest Wi-Fi networks, while widely available, often use captive portals, browser-based login pages designed for human users, which present a major obstacle for embedded devices lacking graphical interfaces. This research addresses the unexplored challenge of enabling autonomous connection to such networks for resource-constrained embedded systems, specifically using the ESP32 platform. By investigating how these devices can independently detect, negotiate and authenticate through various captive portal workflows, this study explores the technical feasibility, resource implications, performance trade-offs, and security risks of automated guest Wi-Fi onboarding. The results aim to inform the development of robust and self-sufficient IoT systems capable of operating securely in dynamic public network environments.
