WiFi Analyser

WiFi Analyser is a free, browser-based tool that digs into Wi-Fi problems at the 802.11 MAC layer. You upload a PCAP file (a packet capture of your wireless traffic) or describe your symptoms in plain English, and it returns a root cause analysis with vendor-specific fix commands in under 15 seconds. It reads every frame in your capture — not just a sample — and runs 240+ protocol checks grounded in IEEE 802.11-2020, MITRE CVE, and NIST NVD standards. The tool supports all major Wi-Fi generations from 802.11n through Wi-Fi 7 (802.11be), and covers security protocols like WPA2, WPA3, EAPOL, and 802.1X.

The analysis happens entirely in your browser — your PCAP is processed in memory and discarded, never stored on a server. WiFi Analyser includes 65+ automated anomaly detectors that flag issues like KRACK replay, PMKID cracking, evil twin patterns, cipher suite downgrades, and roaming failures. It also offers a symptom-first mode if you don't have a PCAP: just describe what went wrong, and the AI engine will suggest possible causes. The tool is validated by CWNE-certified engineers and references real CVE entries for each security finding.

WiFi Analyser is built for network engineers, IT administrators, and security researchers who need to troubleshoot Wi-Fi issues quickly without installing software or managing license keys. It replaces expensive hardware analyzers like AirMagnet (discontinued in December 2025) and complex tools like Wireshark. Common use cases include diagnosing client authentication failures, auditing enterprise networks for protocol-level vulnerabilities, and verifying roaming performance across access points. The tool is free, requires no signup, and works on any modern browser.
