WiFi Analyser is a free browser-based utility that offers in-depth analysis of 802.11 protocols, delivering AI-backed diagnosis of potential network issues. Designed with a foundation in IEEE 802.11-2020 and MITRE CVE data, it helps identify issues right at the frame level. Users can upload a PCAP file or describe their networks symptoms to receive an instant root cause diagnosis. WiFi Analyser aims to replace the complexity experienced with alternatives like Wireshark, and it doesn’t require installations, license keys or expiry dates.The tool completes over 240 adversarial protocol checks, reviewing each frame to identify anomalies, vulnerabilities, and offer potential fix commands. With the ability to work entirely within a web browser, the data analyzed is never stored, ensuring user privacy.An additional symptom mode is also available for problem diagnosis when no PCAP is present. While packed with rich features, including deep frame decoding, AI root cause engine, comprehensive security checks, and browser-only privacy features, it remains accessible to users of every AP brand, making analyzation and issue resolution instant and hassle-free.WiFi Analyser prides itself on its offensive-first detection model, viewing the users data capture as a potential attacker would, identifying vulnerabilities such as an offline-crackable handshake, unprotected management frames, and downgradeable cipher suites.An important note is that this tool is equally privacy-focused in addition to being powerful, all data is processed in-memory and discarded post-analysis, ensuring user data is never kept.
