This article explores how you can determine the various computers and devices that are connected to your home Wi-Fi network with the help of a free application called Who Is On My WiFi. The necessary steps were briefly discussed, as well as other helpful tips.
Is your home wireless internet connection not as fast as it used to be? Somebody within range could be hogging your bandwidth and getting free internet connection from your Wi-Fi network. You could also be connecting too many devices at a time to your network.
The worst-case scenario: Cybercriminals could be piggybacking on your Wi-Fi network, holding you potentially liable for criminal activity. As a security measure, you might want to know how to identify all the various devices you have connected to your home network. Here’s how to do that if your computer is running on Windows OS.
The Solution: Who Is On My WiFi
Download the free application Who Is On My WiFi at whoisonmywifi.com, and then read the tutorial steps when you open the installed program.
A network scan will be initiated. Who Is On My WiFi will then launch a window screen that displays a list of IP addresses. Each IP address is detailed with its associated MAC address and respective local IP address. For computers and other devices that are hardwired or are connected to your network through an Ethernet cord, you should see a “no” in the Connected field.
The MAC address, or the media access control address, indicates the network adapter installed on your PC. To determine the MAC address, enable desktop mode in Windows, right-click on the internet connection icon on your system tray, and choose Network and Sharing Center. Under the name of your network connection, click the Details button to show the network connection details window. You should find the MAC address listed as the physical address.
For your Android device, tap Settings, and select About Device. The MAC address is typically listed under Status on Android smartphones and tablets.
To find out which device is not supposed to be on your Wi-Fi network, go through the list one by one.
If there are a lot of connected devices, turn them on one at a time so you can identify them. For mobile devices, you can readily obtain their local IP addresses. Just tap on the icon for currently connected Wi-Fi network on your Android smartphone or tablet. There is a Description field, which you can fill with the appropriate device-specific label.
Is there a connected device that’s not supposed to be on your list of approved devices? If so, then change your password. If you own a wireless router, simply use the login credentials you previously used upon setting up the device. If you have a modem-router combination that was installed and provided by your ISP, call technical support for help in resetting your password.
