That means your WiFi network may well be vulnerable to malicious hackers or those who simply want to use your broadband Internet access for free. Internet access is relatively inexpensive, but some people just want it for free; while others have more nefarious purposes in mind.
WiFi technology is everywhere these days and it seems almost every electronic device around has a wireless network connection of some sort. Laptops, tablets, smartphones, digital cameras, printers, gaming consoles, smart home devices, and many other things can connect to each other or the internet through a WiFi connection. A wireless network setup also presents its own set of problems when it comes to your own home network and the devices attached to it.
Setting up your own WiFi network with adequate protection like WPA2 and a strong password is vital. But that still doesn’t mean other people aren’t using your network without your knowledge. It’s possible friends, neighbors, or family members have shared the WiFi credentials with others and people you don’t know could have access to your network and your shared files. While many routers have additional security measures such as MAC address filtering, these might not be configured or someone has circumvented them.
A lot of modern routers will give you a list of the wired and wireless devices making a connection to the network, but some do not and some people wouldn’t actually know how to find that information. Another simple way is using a tool to get the list of connected devices, here’s 7 for you to try out.
1. Wireless Network WatcherWireless Network Watcher is another one of Nirsoft’s small and useful tools that does what it’s supposed to very well. The good thing is it requires no setting up of IP address ranges and starts scanning your main network adapter automatically for connected devices. If you wish to scan a different adapter or a custom IP address range, use the Advanced Options by pressing F9.
Scanning the IP range is fast and only takes a few seconds, after which you get information like IP address, device name, MAC address, adapter manufacturer, detection count, and activity state. The “User Text” column can be used to enter your own custom message or label to help with identification. Double click the entry to add your own text.
While Wireless Network Watcher is open, a background scan continuously looks through the IP range to detect new and disconnected devices. You can set a tray balloon and audio warning when devices are detected or disconnected. Turn on “Put Icon on Tray” to enable tray notifications. The background scan interval can be set from the Advanced Options window (F9). A portable or installer version is available.

2. Fing Desktop
Fing Desktop is the PC and Mac version of the popular Fing mobile app. A drawback with Fing is you have to create a free online account but temporary email services do work. The installer is also a sizeable 70MB+. Once you have created your Fing account, installed the software, and connected the two together, click on Scan for devices in the “Your current network” section of the Home window.
Fing has the best device identification system we’ve seen to try and detect what’s on the network. The details column will likely already show an accurate description, the type and class of device, and even the operating system of a remote device. If it doesn’t, click on a device in the list. You’ll get a whole page of information about the connected device, the option to manually edit the name, and a recognize button.
With recognize, you can manually search for and find the right name from an internal database. You can even use a QR code or a local web address to help identify connected devices. Fing is more likely than any other program to help correctly identify tricky or unknown devices. Using the “See insights” button shows everything as categories like brand names, product types, used operating systems, and smart home.

3. SoftPerfect WiFi Guard
WiFi Guard is like a more basic version of SoftPerfect Network Scanner that is more suited for detecting unknown or unauthorized network connections. It will scan your network for connected devices and rescan every xx minutes, popping up a message if a new unknown connection has been found. Softperfect made many of their tools shareware only a few years ago, this is the last free version of WiFi Guard from 2017.
If you have more than one active network adapter the program will pop up the settings window on launch to select the adapter you want to scan. Otherwise, you will be taken to the main window where pressing Scan Now will detect all devices connected to the network.
For every red marked connection you know is authorized, double click on it and tick the “I know this computer or device” box, that will tell the program the device is known and to ignore it on scans. While running or minimized, WiFi Guard will rescan between 0 and 60 minutes (default is 30 mins) and popup a message on screen if a new unknown device has been detected.
Download Softperfect WiFi Guard
4. GlassWire
GlassWire is a very well known piece of software that is part firewall, part network activity monitor, and part network usage monitor. It’s also a very visually appealing program with a great looking user interface. Another feature it has is being able to scan the network and list connected devices while notifying you about their activity.
Once you install GlassWire, you don’t have to set anything up to see the connected WiFi and ethernet devices. Just press on Things at the top of the window and the list will be shown. There is information for IP address, MAC address, first seen time, and the network adapter manufacturer. Hover over the name and a small box will appear to the right where you can enter a more recognizable name or label.
GlassWire can scan for devices every xx minutes. Enable the “Things scan interval” and adjust the time in Settings > General. There’s also an option to show desktop notifications when devices are joining or leaving the network, or when new unknown devices connect. Go to Settings > Security, click the Unlock button, click on “Things Monitor” and set the notification to what you want.
Download GlassWire
5. Advanced IP Scanner
This is an all round network administration tool that can do a number of tasks in addition to scanning your network for connections. There’s also remote options to Wake-on-LAN and shutdown, connect via HTTP/FTP as well as remote control with Remote Desktop and Radmin. Of course, those features are handy but unnecessary for simply scanning your network for wireless connections.
By default Advanced IP Scanner will set the address ranges for all connections on the computer, only the range that the WiFi connections are likely to be on will need to be scanned, such as 192.168.0.1 – 254. If you only have one active connection, there’s no need to touch the IP range.
After the scan, all connections will show along with the wireless device manufacturer, MAC address, and its name. Advanced IP Scanner doesn’t have to be installed and the option to run it as portable can be selected when running the setup executable. If you want to easily identify less obvious entries in the future, right click on the connection and select either Rename or “Edit comment” to add your own note.
Download Advanced IP Scanner
6. Angry IP Scanner
Angry IP Scanner is a Jave based multi platform tool that also works on Mac and Linux. This will obviously mean the Java Runtime Environment needs to be installed on your computer. The tool simply pings every IP address in the selected range for a response and then displays the result along with the information you ask for in the Fetchers window.
You can enter a range of addresses yourself or click the IP button and select the correct network adapter. Then click the drop down to its right to choose the range, /26 will scan up to 63, /24 will scan up to 255 and etc. You can also choose your own IP list text file if you have a complicated setup. The scanning process is quite fast because the program scans using multiple threads.
To see only the hosts that respond to a ping, go to Preferences > Display and choose “Alive hosts only”. The Fetchers for comments, MAC address, and MAC vendor are not turned on by default so you will have to enable them yourself. Double click an entry in the list to add your own comment.

7. Who Is On My WiFi
Sadly, the last free version of Who Is On My WiFi (4.0.5) was in 2018 as the developer shifted focus to its paid analytics service. This tool’s main task is to identify devices your network and warn you when unknown connections are made. You control which connected devices are classed as known or unknown.
On the first launch, cancel the wizard and the program will start a scan (it looks like nothing is happening). If you need to set a custom IP range different to the one shown in the interface, go to Settings > “Scan Options” and enter the range you need. If you are not sure go to the Diagnostic tab in Settings and click “Detect IP Ranges” to see what your network is currently using.
Select each known connection in the list and set its state to KNOWN from the drop down. Optionally add a description by double clicking on “TYPE IN NAME”. Finally press Save Changes. Who Is On My WiFi pops up a visual and audible message when an unknown network device is detected. By default, it will scan every 5 minutes although you can change this time to between 5 and 30 minutes in the settings.
Who Is On My WiFi requires .NET 3.5 to be installed on Windows 10 or 8. During testing, it didn’t pop up a tray notification on some Windows 10 machines while it did on others.

Thank you.
ReplyI used Who Is On My WiFi for years. Recently it stopped letting me mark unknown devices as known, and enter a name/description for them. I contacted the vendor and learned it is no longer supported. This is unfortunate as it did exactly what I wanted, and no more.
ReplyI noticed the warning ‘A device is connected to HotSpot’ on my Android Huawei
Honor. Rcently I have notice that my data credit was expiring well before the 30-day
time limit whereas before I always had 1/2 GB in hand. I understand from these
comments that youngsters are buying apps for stealing WiFi from around them. This
app must circumvent my password, which is extremely complicated, and fear that their
scanning will be successful again very soon. As I only use HotSpot to piggyback with
another phone when out of credit I was not too concerned. BUT, on further reflection,
I very much feel that my credit is being stolen in the few days leading up to the expiry
date of the Data all the time and without using WiFi on those occasions at all. Any
suggstions as to how I can combat these thieving bxxxxxds would be most welcome. I
have no idea how to use ENCRYPTION if that is one of the kindly suggestions.
Glad I found this! At the apartments where I live, we’ve been having an ongoing issue with people (mostly teenagers) hanging around the buildings and using apps that let their devices connect to other people’s wifi. Now we don’t have to worry about if there are unknown devices connected to our internet. Thank you!

Well I can see everything via router settings.
I can even limit accounts, log them off, change their speed

ReplyNice update. I’m quite a big follower of your posts. I also work around to find the solution but not like you (haha).
ReplyIn addition to having MAC filtering + WPA2 security enabled on my router, I have flashed it using DD-WRT as well. The DD-WRT interface shows at a glance all DHCP clients that have been assigned IP addresses

Today there are lots of ways to get access to the Internet. One of them is probably the most commonly used method at home. It is based on using a wireless router that distributes your Internet connection to every single corner of your home. However, you cannot restrict its range, which means that the signal will be available far beyond your house walls. Sometimes, there are people that can take advantage of that and use your wireless Internet for free. If you need to know all currently connected devices to your wireless network, you can download and install Who Is On My Wifi 3.0.2 for free.
Features
- Scans for intruders every few minutes
- Notifies you immediately
- Generates e-mail notification
- Allows you to block every listed device
- IP address scan range can be set
This app is very small in size and requires very few system resources. You can install in on any Windows OS version and on any desktop or laptop computer. The only thing that Who Is On My Wifi requires is Microsoft.NET Framework 2.0 or a higher version. This utility is developed to constantly scan your wireless network and to list all devices currently connected to it. You can set the scan frequency to be between 2 and 10 minutes. A pop up window and/or a sound can notify you in case anything is not quite right. You can also make the system send you e-mails in case you are not in front of your PC.
