NetStumbler for Windows 7
The latest version of NetStumbler is 0.4.0 and was release over 5 years ago on April 21, 2004. The officially supported operating systems do not include Windows 7 or Windows Vista for obvious reasons.
Some users have reported being able to use NetStumbler version 0.4.0 on Windows Vista by running NetStumbler in Windows Vista Compatibility Mode. Instructions for configuring Windows Vista compatibility mode for NetStumbler are below and should be the same for Win7.
Configuring Windows Vista or Windows 7 for Compatibility
To configure the compatibility mode for an application, just locate the installation directory (C:\Program Files\Network Stumbler\) and right click on the .exe (NetStumbler.exe), selecting Properties from the menu.
Select the Compatibility tab as shown in image below.
This didn’t work for me. I didn’t spend too much time researching why, but the reason is most likely because NetStumbler itself doesn’t work with all wireless cards even when using Windows XP or Windows 2000.
Other Options Instead of NetStumbler
Thankfully Windows 7 is intended to be an incremental upgrade to the Windows line, with the goal of being compatible with applications and hardware with which Windows Vista is already compatible.
This means that all of the other options that we know about already for Windows Vista should work with Windows 7.
1) Use netsh command.
