This data includes the SSID, BSSID, PHY Type, Signal Quality, Receiving rate, Transmission Rate, Authentication Algorithm, Channel Number, Total number of transmitted/received frames, and more. All are shown from a clean interface that is a signature of Nirsoft apps. There are several options to choose from, like Always on Top, Put Icon on Tray, and font selection.
