Wireless Network Watcher doesn’t require any installation process or additional dll files. In order to start using it, simply extract the executable file (WNetWatcher.exe) from the zip file, and run it.
If you want, you can also download WNetWatcher with full install/uninstall support (wnetwatcher_setup.exe), so a shortcut for running the app will be automatically added into your start menu. After running the app, it automatically locates your wireless adapter and scans your network. After a few seconds, you should start see the list of computers that are currently connected to your network.
If from some reason, WNet Watcher failed to locate and scan your network, you can try to manually choosing the correct network adapter, by pressing F9 (Advanced Options) and choosing the right network adapter.
