inSSIDer

inSSIDer is an award-winning free Wi-Fi network scanner for Windows Vista and Windows XP. Because NetStumbler doesn't work well with Vista and 64-bit XP, we built an open-source Wi-Fi network scanner designed for the current generation of Windows operating systems. inSSIDer was discussed by Lifehacker and Tekzilla!

What's Unique about inSSIDer?

  • Use Windows Vista and Windows XP 64-bit.
  • Uses the Native Wi-Fi API.
  • Group by Mac Address, SSID, Channel, RSSI and "Time Last Seen."
  • Compatible with most GPS devices (NMEA v2.3 and higher).

How can inSSIDer help me?

  • Inspect your WLAN and surrounding networks to troubleshoot competing access points.
  • Track the strength of received signal in dBm over time.
  • Filter access points in an easy to use format.
  • Highlight access points for areas with high Wi-Fi concentration.
  • Export Wi-Fi and GPS data to a KML file to view in Google Earth.

Trying to Identify Interference?

"Those looking to employ something more than blind guesswork when it comes to identifying potential wireless interference will appreciate the capabilities of MetaGeek’s Wi-Spy 2.4x, a spectrum analyzer that can help you discern how well—or poorly—your wireless signals actually fare in the air." -Joseph Moran Wi-Fi Planet
