Signal History
The Signal History window displays a graph of Wi-Fi network signal levels over time. Networks can be chosen to graph by selecting the checkbox to the far right in the Networks table. More than one network can be chosen to graph at one time. Up to 500 seconds (about 8 minutes) of signal level history is graphed. Right clicking on the graph provides the options to Reset Chart, which clears all graph information, and Select All Networks, which graphs all of the networks currently in the Networks table (or the 10 strongest if more than 10). Hold the Shift key down and left click with the mouse to zoom in on the graph. Use the Alt key with a left click of the mouse to zoom out on the graph.
