How to check if anyone is stealing your wireless connection

One of the things that you probably checked when choosing your router was how far the wireless signal would reach. There is little more frustrating that not being able to use your laptop and tablet in every part of the house. You may have invested in range extenders and repeaters, but the problem is that the further your throw your wifi signal, the greater the chance that it could be picked up by other people.

Of course you should have password protected your connection, but this is not necessarily going to stop other from “borrowing” your bandwidth. Using Who’s On My Wifi you can check to see that there are no unauthorized hangers-on — much quicker and easier than checking in your router’s settings.

Grab yourself a copy of Who’s On My Wifi (it’s available free of charge) and run through the installation. There’s nothing special or unusual about the installation process, and you can be up and running in a couple of moments.


Launch the application and click the Continue Setup button and you’ll be guided through the process. Follow the instructions, starting by clicking the Scan Now button. You’ll have to wait for a little while as your network is scanned and connected devices are detected.


You’ll be presented with a list of all of the devices detected on your network and you will then need to spend a little time indicating which devices you recognize and trust. From the dropdown menus marked UNKNOWN, select the KNOWN option for each device you know to be your own. When you’ve done this, click Save Changes.

You’ll then be instructed to perform another network scan and once this is complete, Who’s On My Wifi is ready to use.


You can then just leave the program running in the background and you’ll be warned as soon as a new, unknown device connects. You can decide how you would like to deal with it yourself — Who’s On My Wifi will not keep your protected, but it will keep you informed.
