AP scanner

Nearby Wi-Fi access points with rich detail per BSSID, grouped by physical AP so a multi-radio enterprise box surfaces as one row that expands to its virtual BSSIDs.

Per-BSSID detail

• SSID — network name (hidden SSIDs surface as (hidden))
• BSSID — MAC address of the radio
• Channel + width — 20 / 40 / 80 / 160 MHz
• Band — 2.4 / 5 / 6 GHz
• RSSI — received-signal strength (dBm)
• SNR + noise floor — signal-to-noise and ambient noise
• Security — ordered WPA3 > WPA2 > WPA > WEP > Open
• PHY modes — 11b / g / n / ac / ax
• Wi-Fi generation — Wi-Fi 4 / 5 / 6 / 6E
• OUI vendor — looked up from the BSSID’s first 3 bytes
• Beacon interval + country code

Per-physical-AP grouping

Multi-radio APs broadcast a separate BSSID per radio per SSID — easily 5+ BSSIDs from one physical box. The scanner groups by the MAC /48 prefix so one row per AP appears in the list. Click to expand to see every virtual BSSID. The header surfaces N APs · M BSSIDs so you can tell density at a glance.

Per-OS

• macOS — uses in-process CoreWLAN (CWInterface). This matters: the OS attributes Location Services to ShellYard itself rather than a subprocess like system_profiler (which returns redacted data on recent macOS). First run prompts for Location Services permission.
• Linux — uses nmcli.
• Windows — uses netsh wlan show all.
