How to Check Your Wi-Fi Network for Suspicious Devices

Are you worried that strangers or hackers might be on your Wi-Fi network? Here’s how you can check and how to do something about it.

Since you first installed your Wi-Fi network, you’ve probably connected various devices and even allowed visitors to access your network. As a result, the list of attached computers, laptops, smartphones, tablets, and smart home equipment is likely quite long.

However, if you aren’t already, you should be regularly checking the devices connected to your network. Hidden among all the legitimate connections may be suspicious devices with odd names and gadgets you don’t recognize.

Let’s take a look at how to identify devices on your network.

How Do Wireless Connections Work?

When you connect a device to your network, it is assigned a local IP (Internet Protocol) address. This is a unique numeric label that identifies each device on the network. These internal IP addresses commonly take the form of 192.168.0.xxx, where xxx is an identifying number between 1 and 255.

Most routers use DCHP (Dynamic Host Configuration Protocol) to automatically assign IP addresses to devices upon connection. However, these IP addresses are dynamic, so they may change over time as the device drops off and reconnects to the network.

If you don’t want a device’s IP address to change like that, you’ll have to assign it a permanent static IP address specifically. However, in most cases, you may not need a static IP address at all.

As dynamic IP address frequently change, they aren’t a useful way to identify a device. Instead, you can use the machine’s Media Access Control (MAC) address. This is a unique identifier assigned by the manufacturer.

These internal IP addresses identify the devices attached to your Wi-Fi router. However, it is the router itself that connects to the internet. Your Internet Service Provider (ISP) assigns your household an external IP address.

As a result, your network devices share the same external IP address, but they have unique internal IP addresses, which is how the router differentiates between them.

Given these addressing mechanisms, there are few ways you can approach identifying devices on your network.

Checking Devices on Your Network with Your Router

The majority of household routers have a dedicated web interface where you can access information about the router, external internet connection, and connected devices. In most cases, you just need to enter 192.168.0.1 into the address bar on your browser.

However, if this approach doesn’t work for you, it’s possible to find your router’s IP address using Command Prompt on Windows. Use the ipconfig/all command, and look for the Default Gateway address. That said, this is just one of many commands you can use to manage wireless networks in Windows.

To protect your network, you’ll need to log in to access this interface. Initially, these credentials are set to defaults, and the username is often listed as admin. However, the first time you log in to the router, you should change these to something more secure.

The next stage will vary depending on the brand of your router, firmware, and ISP. However, generally, there should be a setting named Device Connection Status or similar. This should list all devices currently connected to your router, including wireless and wired connections.

For each device, you’ll be able to view the IP address, MAC address, and device name. The manufacturer often sets the device name, so it should be easy to identify your smartphone and laptop. However, peripherals, smart home equipment, and older devices may not have a name configured or simply show a jumble of characters.

If you notice something that you don’t recognize, you can power off each of your network-connected devices one at a time. If a device remains after everything is disconnected, this could be evidence of an unwanted or potentially sinister device connected to your network.

Although this is the most straightforward method, it requires logging onto your router regularly to view the connected devices. It also doesn’t provide any tracking or detailed information. Consequently, this is a great starting point, but you may wish to dig further into your network.

Checking Devices on Your Network with WNW

On Windows, there are many ways to identify devices on your home network. However, one of the most effective tools is Wireless Network Watcher (WNW) from NirSoft. The software scans the network you’re connected to and returns a list of devices and their MAC and IP addresses.

Although you can view the list in WNW, there’s also the option to export it to HTML, XML, CSV, or TXT. While this sounds a similar method to checking on your router, WNW has a few benefits. You don’t need to login to the router to perform this check, and it can automatically refresh the list.

It’s also possible to create alerts for when a specific device is added to or is removed from your network. The software records all machines seen on the network and the number of times each has connected.

The tool can either be installed on your computer or run as a portable app without installation. Downloading the WNW ZIP edition means you can copy it across to a USB flash drive and take it with you for use on any computer.

Checking Devices on Your Network with Fing

If you’d like to make the process easier across multiple, cross-platform devices, consider using Fing. This desktop and mobile software helps you keep track of devices connected to your network, just like WNW, and allows you to manage this across multiple networks on macOS, Windows, Android, and iOS devices.

Once installed, run the Network Discovery feature, and you’ll be presented with a detailed list of all the devices connected to your current network. This returns the IP and MAC addresses and a user-configurable name.

You can use Fing locally on your device without an account, but signing up allows you to access stored networks on any device with Fing installed. As a result, you can sync multiple network configurations, set email alerts for changes, and perform internet speed tests, which are recorded to view any changes.

Fing is free to use, although you can complement it with Fingbox. This hardware product connects to your router, allowing you to monitor the network, set internet schedules, and improve security.

Download: Fing for Windows | macOS | Android | iOS (Free)

Keeping Your Network Secure

There are many reasons to keep track of the devices joining your network. On a practical level, knowing each connected device’s status helps when you need to troubleshoot network issues. Importantly, it also allows you to keep your network secure. An unknown device could be freeloading on your connection and turn out to be malicious.

In that case, the suspicious device could be used to compromise your network, keep tabs on which devices, and therefore people, are at home, and even gather sensitive data. Tools like WNW simplify the process, but Fing is arguably the simplest to use. The cross-platform sync makes it easy to keep tabs on your network, no matter where you are.

Is your internet connection secure? Here’s what you need to know to stay safe and secure on any network you connect to.

how to check if wifi is really connected in Android

I’d like my android device to connect to a wifi hotspot. I created a new wificonfiguration and add it into the wifimanager , this wificonfiguration has NetworkId .Then I invoke the function wifi.enableNetwork(NetworkId, true).

After that, I think the supplicant will go through obtaining ip address, authentication, and at last physically connect to the hotspot. So is there a way to identify if the wifi is physically connected or not?

I would prefer a handler-like method.

Check wifi device connected to your

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.

Wireless 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.

Wireless network watcher

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 desktop

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.

Похожее:  Если вы не хотите делать широковещательный приемник попробуйте попробуйте

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.

Softperfect wifi guard

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.

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.

Glasswire Things

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.

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.

Advanced ip scanner

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.

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.

Angry ip scanner

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.

Whos on my wifi

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.
