The Dashboard panel provides users with a real-time snapshot of the current Wi-Fi environment. You can show or hide the dashboard and change its location (left or right) using the View => Dashboard menu item.


If TamoGraph detects a Wi-Fi adapter that can be used for passive surveys, the dashboard includes the following indicators:

  • Scanner progress – the circular indicator that visualizes the scanning progress. The circle represents a scan cycle, i.e. the time needed to sweep all selected channels once.
  • Scanner cycle duration – the text above the horizontal line inside the circle that indicates the time in seconds needed to sweep all selected channels once.
  • Number of available adapters for passive surveys – the number below the horizontal line inside the circle that indicates the number of adapters being used for passive surveys.
  • Scanner cycle duration recommendations – the color of the circle that indicates whether the scan cycle duration is optimal. A green circle indicates optimal scan cycle duration. A yellow circle indicates somewhat lengthy scan cycle duration. A red circle indicates that scan cycle duration is too long and needs to be shortened for better results. Hovering the mouse pointer over the circle reveals a hint window with extended information and recommendations.
  • Current signal strength – two bar indicators (for the 2.4 and 5 GHz bands) that display the signal strength of the APs being monitored. Clicking on the gear icons to the right of the indicators allows you to specify which AP signals should be displayed. You can set the indictor to display either the signal of the strongest of the selected APs (by selected, we mean the APs that are checked in the AP list,) or the signal of the strongest AP for the selected SSID. Double-clicking on the bars toggles the display between signal strength in dBm and percent.
  • Number of APs currently visible – two text labels (for the 2.4 and 5 GHz bands) that display the number of APs that have been seen recently.
  • Signal strength chart – two histograms (for 2.4 and 5 GHz bands) that display the signal strength history.

While performing active surveys, the dashboard panel is automatically expanded to include more data related to the active survey being conducted. This includes the associated AP name, channel number, PHY rate, noise, SNR levels (if available), and a chart that displays the metrics being measured: throughout, loss, round-trip time, PHY rate, and signal level. The speaker icon allows you to enable or disable signal level vocalization; when the button is pressed, the computerized voice will periodically pronounce the current signal strength as you conduct the active survey. Double-clicking on the AP name toggles the text between the AP name, its MAC address (a.k.a BSSID), and SSID.

Both charts can be customized by using the context menu that is displayed when you right-click on the charts.
