Find out who is using your WiFi

Do you suspect your neighbour is using your WiFi network without your consent? Rather than spending hours staring at your router’s administration console to find out who is using your WiFi, you can use Wireless Network Watcher – a free utility that scans for devices currently connected to your network.

Once launched, the utility scans the network you are connected to and display the devices currently using your WiFi connection along with their corresponding IP address, Mac Address, Computer names and Network Adapter name.

That’s cool! But what if your neighbour is not connected at the moment you are running the scan? You will obviously not see his or her computer in the list. If you want to get notified as soon as someone attempts to connect to your WiFi network, you will need to tweak the app a bit.

Go to Options and select the following: Put Icon On Tray,Start As Hidden, Tray Balloon on New Device, Background Scanand Beep on New Device.

We will now set the interval between two scans. To do this click on Options > Advanced options or press F9. In the new window, enter the desired time in seconds between scans, for example 900 (equivalent to 15 minutes).

Now each time someone connects to your WiFi Network, a balloon notification will appear in your tray icon.
