Wireless connections are so common these days as the economic crisis. And it was not expected that programs for such networks. We have a lot to the strengthening of WiFi security, as well as for practical network monitoring.
In this latter sense we know practice, portable, in Spanish and free utility for Windows, called WirelessNetView that lets you detect wireless networks in range, and observe all the activity is taking place in them so simple.
WirelessNetView shows you the data associated with each network. From the measured signal (or signal strength, rather, in percentages) and also if the network has security, authentication, encryption. On the other hand, shows the MAC address.
The data from the wireless networks detected by WirelessNetView are updated at intervals of ten seconds, updating the data based on the time of the tests performed. It is a practical tool for wireless monitor.
