What the diagnostic menu and report can tell you
The primary purpose of Wireless Diagnostics is to examine wireless connectivity. Its analysis can flag detected issues and provide possible solutions and Wi‑Fi best practices. If you need someone else to inspect the results, the tool can generate a compressed diagnostics archive. Look in /var/tmp for a filename that starts with WirelessDiagnostics and ends in .tar.gz. Share the archive with a network administrator, service provider, or IT support person when appropriate.

Those additional details and controls may vary by macOS version; rely on the Wireless Diagnostics option and its on-screen analysis as the core workflow.

When to use a different diagnostic
Wireless Diagnostics looks at Wi‑Fi connectivity; it is not the same as Apple Diagnostics. Apple describes Apple Diagnostics as a separate tool for testing device parts and performance and identifying components that may need repair. If symptoms point to a hardware fault rather than a wireless connection issue, consult Apple’s February 29, 2024 announcement about Apple Diagnostics and pursue hardware support. For network issues, the generated Wireless Diagnostics report is more appropriate to share with whoever manages or supports the network.
