Wi-Fi Scanner for Mac

Overview of the application

WiFi Scanner is a macOS utility for discovering and managing wireless networks. It provides more in-depth scanning and monitoring than the default Wi‑Fi tools bundled with macOS, making it useful for anyone who needs clearer insight into nearby wireless signals.

Who benefits most

• Network professionals and technicians who require detailed diagnostics and continuous monitoring.
• Casual users who want a more accurate view of signal strength and coverage than the system Wi‑Fi menu provides.

Key capabilities

• Filter and sort networks using identifiers and signal metrics such as SSID, BSSID, RSSI, and channel frequency (2.4 GHz or 5 GHz).
• Perform comprehensive scans for analysis and long‑term monitoring of wireless environments.
• Monitor signal strength precisely to help map coverage or locate signal dead zones.
• Play an audible alert when a network reaches a signal level suitable for a reliable connection.
• Join a detected network directly from the app using the “Join” action, although the macOS Wi‑Fi menu can also be used for connection management.
• Manage and keep track of multiple networks within a single interface.

Connecting and practical notes

To connect to a network from the app, click the “Join” control next to the network entry. If you prefer, use the macOS Wi‑Fi menu (formerly AirPort) to connect in the usual way. The audible alert option is handy when you’re moving around and want to be notified the moment a reliable connection becomes available.
