Wireless Network Watcher (WNW) is relatively benign. If you’re not smart enough to change the defaults on your home wireless router, you should have someone help you. Wireless access points are NOT something to trifle with.
Used to be that having an insecure LAN was no big deal, as physical access was required to do any damage. With wireless, however, your entire network is at risk if the AP is not secure.
WNW only enumerates endpoints on a wireless network that is A) insecure, B) unsecured, C) unencrypted. It’s helpful to use in your home environment to get an idea as to what’s out there, but it’s not exactly a useful forensic tool against entities who know their way around IPSEC, RADIUS, or have their home networks properly secured.
