A free WiFi wireless network scanner with signal strength.

A review by Felix Cheng

inSSIDer is a wireless networking utility that allows you to find wireless networks in your area and control, in a graphics mode, the intensity of their signals.

Specifically, inSSIDer can detect any wireless networks that offers coverage in your area and will list all the details in the main user interface: SSID, MAC address, channel, RSSI, security and network type, speed and intensity of the signal.

Furthermore, using a plot, inSSIDer will allow you to monitor the quality of the signal as a control parameter using the indicator that reflects the strength or intensity of the received radio signal (RSSI).

inSSIDer can manage WiFi connections and snif network traffic.

Features and highlights

  • Works with Windows XP, Vista and 7 (32 and 64 bit)
  • Compatible with most GPS devices
  • Track the strength of received signals in dBm over time
