Clicking on a row in the information chart highlights the row in blue and displays that network’s information in the SSID Details section. This is where most of the information gathered about a network is displayed.
More specific network information is shown in this area, along with a graph plotting the Signal and Noise of a selected network. The more signal and less noise you have, the higher (and better) the Signal to Noise Ratio will be.
Press the Info Icon on the left to view each specific scan result from that network.
