YouScan gives network engineers a live view of every AP, radio group, channel, and interference source — with structured sweep reports built in.
Install with one command
curl -fsSL https://youscan.3am.it/install.sh | bash
Continuously scans via CoreWLAN and presents every visible AP with RSSI, SNR, channel, band, vendor, and estimated distance.
Identifies which BSSIDs originate from the same physical radio using a MAC fingerprint heuristic — handles both first-octet and last-octet MLO variants.
Counts unique competing radios per channel and band. Channel chart splits Protected vs External when a filter is active.
Normalises the noise floor across bands so 2.4 / 5 / 6 GHz SNR values are comparable in a single column — not just same-band guesswork.
Detects Open, WEP, WPA/WPA2/WPA3 Personal and Enterprise per network. Open networks are highlighted immediately.
Pulls PHY mode, MCS index, spatial streams, guard interval, and CCA% from wdutil info — sudo password asked once per session.
Event → Area → Sweep → Checkpoint model. Generates self-contained HTML reports with coverage matrix, channel overlap map, and per-checkpoint diagnostics.
Flags BSSIDs advertising your protected SSIDs with unexpected MAC prefixes — a fast passive evil-twin heuristic, no association needed.
Export the current filtered view to CSV, or copy rows directly into Excel with ⌘C. Security type, radio group, and CH overlap included.
