Setting It Up

After installing Who Is On My WiFi, the all-important “Setup Wizard” will load. Click “Continue Setup” to begin.


The first step is setting up this software is scanning your network, specifically nearby ports so it can determine which computers are yours, and then be able to tell from there any unknown computers that may tap into your system.

After clicking “Continue Setup,” the computer will scan your computer and reveal your own computer(s).


It will then ask you to change your computer’s label from “Unknown” to “Known.” To do this, simply click the word “Unknown” with the grey drop-down menu arrow, select “Known,” and then do this for each computer that is yours on your network.


When you’re done, make sure to click “Save” at the top of the screen.


After clicking “Save,” the software will again ask you to scan your network to make sure no true unknown computer is using your network. Click “Scan Now” at the top right of the screen to begin the process.


After this last scan and if nothing is found, it will ask you to minimize the software so it runs in the background. This is a good idea because it scans your network every 5 minutes. You can’t get any more secure than that.
