WiFi Analyser

WiFi Analyser is an analytics tool. Free browser-based tool that analyses 802.11 packet captures with 100+ detectors and AI, returning a ranked root cause, evidence frames, vendor fix commands and a PDF report without an account or install.

WiFi Analyser is a browser-based tool for diagnosing wireless problems from packet captures. A user uploads a .pcap or .pcapng file, and the service decodes every 802.11 frame, rebuilds handshakes and sessions, identifies the scenario automatically and runs more than 100 anomaly detectors. The result is a ranked root cause, the exact frames that support it, a Wireshark display filter to reproduce the finding, and vendor-specific fix commands. The site says analysis finishes in under 15 seconds. The audience is Wi-Fi professionals: field engineers and managed Wi-Fi providers, enterprise network engineers, and security specialists working on WPA2, WPA3, 802.11r roaming, PMF and Wi-Fi 7 multi-link deployments. Findings cite the IEEE 802.11-2024 standard, and the security checks cover items such as PMKID exposure, deauth floods, rogue access points and cipher downgrades. Each capture also receives a health score and a five-level security maturity rating, and the results can be exported as a PDF report with a remediation roadmap. In practice there are three entry points. A capture can be uploaded directly, a device's own Windows WLAN report or macOS log can be supplied for a client-side station report, or Symptom-First mode lets the user describe the problem in plain English when no capture exists. An AI agent can then be questioned about the findings. The page is open about limits: Ethernet-mode captures, missing radiotap headers or missing management frames reduce the analysis, and the evidence section separates what is verified from what cannot be proven. Four small demo captures are offered for trying it out. Captures are processed in memory and discarded, and only a short context block with MAC and IP addresses replaced by session tokens goes to the AI request. No account or install is required, and the service is free. It is positioned against Wireshark-only workflows and as a replacement for the discontinued AirMagnet, making it a lightweight option for fast triage rather than a full survey or monitoring platform.
