Inssider is a Wi-Fi network scanner for Windows Vista and Windows XP. Although NetStumbler, the most popular Wi-Fi network scanner, is free, it hasn't been actively developed for years. We heard complaints that NetStumbler doesn't with Windows Vista and 64-bit Windows XP, so we decided to build an open-source Wi-Fi network scanner designed for the current generation of Windows operating system.
* Works with internal Wi-Fi radio
* Wi-Fi network information (SSID, MAC, data rate, signal strength, security, etc)
* Graph signal strength over time
