With the help of Vistumbler you can scan nearby wireless access points that you can connect to. It also features GPS support.

The tool is packed in a simple interface that consists of a comfortable window, where you can scan for access points with the simple click of a button.

Results shows the status, MAC address, SSID, average and high signal, average and high RSSI, channel number, authentication and encryption methods, together with the network type for each access point.

This list can be exported to VS1, VSZ, CSV, KMZ, GPX or NS1 format for further evaluation. Plus, you can sort results by authentication mode, channel number, encryption method, network type, or SSID.

You can use GPS, view a graphical representation of the access points, ask Vistumbler to play MIDI sounds for all active access points, display functions and COM errors, as well as include filters (e.g. radio type, basic transfer rates).

Other options of Vistumbler let you refresh the network interfaces, view a GPS compass and details (e.g. coordinates, speed, track angle), change the UI language, manage a list of Mac address manufacturers, use cameras, and others.

The application is not a concern to the system's resources, since it uses low CPU and memory. It has a good response time and locates access points quickly. No error dialogs were shown in our tests, and the app did not hang or crash. Unfortunately, Vistumbler is not very intuitive for less experienced users.
