Wireless Network Watcher is a tiny, portable tool and works on all Windows systems (32bit/64bit), and allows you to scan your network to find who is currently using your connection.
How to use Wireless Network Watcher?
Just download (250KB) it, extract, and run it. It will scan and list all devices name, its MAC address, IP address, manufacturer name, etc quickly (currently accessing your Wi-Fi).
From the advanced option (Option – Advanced Option), you can scan for a given IP address range and Network adaptor. After finishing the scanning, the result can be saved as html, text or xml file for future references.
Benefit of using Wireless Network Watcher
You can use the information provided by this tool to block the unauthorized user accessing your internet. For example, in your router settings you can enable ‘Wireless MAC Filter’ to filter out suspected MAC address, hide your device name, or use more secure WPA2 encryption instead of weaker WEP, etc. Note: Scan with it at different times, because it can only detect currently (live) accessing devices. Wireless Network Watcher can be downloaded free at source here.
