Normally, you wouldn’t know who has been on your wireless network unless you go to your wireless router’s admin page to find out. Here, NirSoft just released a small tool called Wireless Network Watcher that can help you easily do the same thing right on your windows computer.
Wireless Network Watcher is a small utility that scans your wireless network and displays the list of all computers and devices that are currently connected to your network. Once a device was discovered, its IP address, MAC address, the name of network card manufacture, and optionally the device name.
The information can be exported into html/xml/csv/text file, as well as copy to the clipboard for later pasting into other program. If you have multiple network cards loaded on your system, you can have the choice to pick which network card to be used for scanning. It’s quite puzzled to me that even I don’t have the wireless card enabled on my laptop yet this little utility still managed to find all the wireless devices connected to the network.
Wireless Network Watcher is a FREE Portable tool that doesn’t require any installation process or additional DLL file. It runs on Windows system from 2000 and up. A nice tool that could come handy from time to time.
