Winner of InfoWorld's Annual Bossie Award

InSSIDer is a free Wi-Fi network scanner for Windows Vista and windows XP. Because NetStumbler doesn't work well with Windows Vista and 64-bit Windows XP, we decided to build an open-source Wi-Fi network scanner designed for the current generation of Windows operating systems.

Benefits

• Inspect your WLAN and surrounding networks to troubleshoot competing access points.
  
• Use Windows Vista and Windows XP 64-bit.
• Uses the Native Wi-Fi API.
  
• 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.
• Group by Mac Adress, SSID, Channel, RSSI, and time "last seen."
  

InSSIDer on Vista

This project was started by Charles Putney on The Code Project. Norman Rasmussen modified the project to use the Managed Wi-Fi C# wrapper for the Native Wi-Fi API. Many thanks to Charles and Norman, as well as the Managed Wi-Fi team for getting this project off the ground.

After we had a basic application working we decided we should release it so that everyone else can use it. InSSIDer is free and open source so that others can join in the fun!

System Requirements

• Windows XP SP2 with .NET 2.0, or Vista
• 1024 x 768 Resolution or Greater
