How to find out who is using your wifi

Is your WiFi stolen? You would like to know the best programs to check if someone is using your WiFi network and how to kick him out.

Do you want to find out who is connected to your WiFi network? What devices are they using and what are their IPs? Do you think that your neighbors are stealing your WiFi? Find out here how to prevent your WiFi from being stolen.

Wi-Fi technology is everywhere and almost all electronic devices have a wireless network connection. However, setting up a wireless network also presents some problems when it comes to a home network and the devices connected to it.

Naturally, creating your own Wi-Fi network with adequate protection like WPA2 and a strong password is vital, but it does not ensure that outsiders are not using your network without your knowledge . Chances are, friends, neighbors, or family members have shared your WiFi credentials with others, and people you don’t even know, have access to your network and shared files.

1. Programs to check who is connected to your WiFi network

A lot of modern routers will give you a list of the wired and wireless devices that make a connection to the network, but others don’t and some people don’t really know how to find that information. You will find below some tools to get the list of connected devices in your network.

1.1. Advanced IP Scanner

It is a network administration tool that can do a number of tasks, such as scanning the network for connections. There are also remote options for Wake-on-LAN and shutdown, connect via HTTP / FTP, as well as remote control with Remote Desktop and Radmin. Of course, it is also useful for a simple network scanner for wireless connections.

By default Advanced IP Scanner will set the address ranges for all connections on the computer, that is, only the range in which WiFi connections are likely to be activated will have to be scanned, such as 192.168.0.1 – 192.168.0.254 . If you only have one active connection, there is no need to touch the IP range.

After scanning, all connections will be displayed along with the manufacturer of the wireless device, the MAC address and its name. Advanced IP Scanner does not have to be installed since it has a portable version.

1.2. Wireless Network Watcher

Wireless Network Watcher is a NirSoft software . The good news is that it does not require configuring the IP address ranges and automatically starts scanning your primary network adapter showing the connected devices.

Wireless Network Watcher scans the IP range in a few seconds, after which it gets information like IP, Device Name, MAC address, adapter manufacturer, detection amount, and activity status.

If you want to scan a different adapter or a custom IP address range, use the advanced options by pressing F9. A portable and installer version is available.

1.3. SoftPerfect WiFi Guard

SoftPerfect WiFi Guard is like a basic version of the excellent SoftPerfect Network Scanner software . This tool will scan the network for connected devices and re- examine every xx minutes, displaying a message if an unknown connection has been found.

For each connection marked in red that you want to authorize, double-click on it and check the box ” I know this computer or device “, which informs the program to ignore the device during scans.

While running or minimized WiFi Guard will scan again between 0 and 60 minutes (default is 30 minutes) and will display a message on the screen if it has detected a new unknown device.

1.4. Angry IP Scanner

Angry IP Scanner is a cross-platform tool that works for Mac and Linux . It is based on Java, which will obviously mean that the Java runtime environment must be installed on your computer.

The tool simply pings all IP addresses in the selected range for a response and then displays the result along with the information you request in the main window.

The scanning process is quite fast. To see the result of all the addresses scanned, go to Tools> Preferences> Show and select ” All scanned computers “, this will reveal other connected devices, possibly not responding to the pings. The portable and installation version is available.

1.5. Who Is On My WiFi

This tool is a little different from the others, because its main task is to identify the computers on the network and notify when unknown or unidentified people make a connection to the WiFi network .

Unfortunately, one of its most useful features of blocking unknown or suspicious connections is only available on a paid subscription, plans start slightly at $ 9.95 per month. The free version, however, still allows you to scan and find devices on the network.

The first thing you should do is configure the address range to scan from the default by clicking on the Settings button and enter the range you need for your network (Scan Options), such as 192.168.0.1-254. If you are not sure about going to the diagnostic tab in settings, click “Detect IP ranges” to see what your network is currently using.

If Who Is On My WiFi is kept running in the background, a visual and audible message will appear when an unknown network device is detected, by default it will be scanned every 5 minutes, although you can change this time from 2 to 10 minutes in the settings .

Be sure to close the Who Is On My WiFi icon in the toolbar if you don’t want to use the monitoring feature.

3. Conclusion

I hope you liked these tools. All of them are very useful to know who is connected to our WiFi network and I invite you to try each one and choose one according to your preferences.

A separate point for Advanced IP Scanner , which is an excellent tool for managing your network and for Who Is On My WiFi , which in its paid version protects your WiFi network by searching, detecting and blocking intruders. Now you can answer the question : who is on my wifi or who is using my wifi .
