WirelessNetView is a freeware application designed to keep an eye on the surrounding wireless networks, logging important information such as signal strength.
The interface is the easiest you can get in this case and it's actually a very good thing because this is practically the simplest mode to monitor network activity around you.
For each network, WirelessNetView displays a bunch of useful details such as last signal quality, average signal quality, authentication algorithm, SSID, detection counter, cipher algorithm, MAC address, company name, RSSI, channel frequency and number.
Once you run the application, it's enough to minimize it to tray and let it do its job. WirelessNetView automatically scans the perimeter and if new networks are found, they're also added to the already created list.
There are numerous options available, including a dedicated tool to beep every time a new network is found, mark the best secured and unsecured network to connect to, add header line to CSV/Tab delimited file and restart Windows wireless service.
In addition, you can decide the update rate (low, medium, high and very high), but also the network security filter, which means WirelessNetView must show only secured or unsecured networks.
There's no help file included in the package, so you may need to search the web if the aforementioned terms sound like rocket science to you.
Overall, WirelessNetView is quite a handy application and because it's free and works so smooth on all Windows versions, it's really worth a try.
