How do I use the Automated Troubleshooting function?

Please note: the Troubleshooting heatmaps are only available for PRO and Enterprise users.

Troubleshooting heatmaps can be used to quickly highlight areas in a zone that have potential issues. The six visualizations are:

  • Issues with SNR
  • Low signal level
  • High noise level
  • Overlapping channels (SIR)
  • Low download rate
  • Low upload rate

Get started with NetSpot WiFi tool for macOS

Note that the color interpretations in the troubleshooting heatmaps differ from those in the other NetSpot heatmaps. If you are reviewing a troubleshooting report, red signifies that this area has a high probability for a problem to occur. Yellow means there is cause for concern. Green means everything is fine.

Remember, no software will ever be the equal of an experienced network specialist. But these tools should at least get you headed in the right direction.
