What is a WDMON file?

A WDMON file contains Wi-Fi performance scan results captured by Wireless Diagnostics, an app bundled with macOS used to analyze a user's network performance. It stores information about the connection of a network to the Internet, which includes the data transfer rate and signal quality, over a specified period of time.

Users typically utilize Wireless Diagnostics when they are experiencing difficulties performing Internet-related tasks, such as browsing the web, streaming content, or sending and receiving emails while connected to a Wi-Fi router.

  • Rate - Transmission rate over time in megabits per second (Mbps).
  • Quality - Signal-to-noise ratio over time in decibels (dB), with lower quality numbers resulting in devices disconnecting from the router.
  • Signal - Signal (RSSI) and noise measurements over time, with high signal and low noise measurements indicating optimal performance.

  1. Select Window → Performance.
  2. Leave the window open as the program collects data.
