RogueScanner

RogueScanner is an open-source utility designed for identifying all rogue wireless devices in your network, in order to remove them and block access to sensitive information on your computer.
After a brief installation procedure, you are greeted by a standard window with a well-organized layout, representing RogueScanner's interface.
Upon deployment you can select the network adapter to be used for scanning, and input the IP address and subnet mask. You can also point out if the adapter is wireless.
RogueScanner automatically performs a scanning procedure and displays the IP and MAC address for each found wireless device, together with the vendor and model.
The statistics and scanning status are shown on the upper part of the screen; these focus on the total scanned addressed, found devices, active threads and pending probes. Unfortunately, RogueScanner does not give you the possibility of copying the list of wireless devices to the Clipboard, or exporting them to file for further analysis (e.g. TXT, HTML).
The app runs on a low quantity of CPU and system memory, so it doesn't interfere with the runtime of other active processes. It has a good response time and works well, without making the operating system hang, crash or pop up error dialogs. Besides the fact that the tool has not received updates for a long time, RogueScanner delivers quick solutions when it comes to detecting wireless devices in your network.
