SoftPerfect WiFi Guard is a free utility for protecting your home Wi-Fi network. SoftPerfect WiFi Guard - a free utility for protecting your home Wi-Fi network Wifi guard a program for detecting other people's connections

Think your home wireless network doesn't need protection? You are deeply mistaken. Most users are confident that applying password protection to a Wi-Fi network is a reliable and safe measure to protect it.

This statement is fundamentally incorrect. It will not be difficult for a nimble and experienced hacker to hack the access key to your network in a short period of time through constant “brute attacks” and gain free access to the Internet. However, in addition to the “free” distribution, hackers can, if desired, intercept your incoming and outgoing traffic, thereby gaining access to your confidential information.

Unfortunately, standard means Wireless network controls from equipment manufacturers are not able to provide the required level of protection. The free WiFi Guard program boasts such capabilities.

After installing WiFi Guard, you only need to carry out a few simple settings so that the utility begins to reliably protect your network. First of all, you have to specify the time period between which the “defender” will carry out full Wi-Fi scanning network and identify attempts or traces of hacking.

A special monitoring window will display all clients who are currently using your network. If unidentified clients are found in this list, they can be quickly blocked. Also, WiFi Guard can perform this function automatically. To do this, you need to create a list of trusted users who will not be blocked when connecting.

Legal users of your network will be marked in green in the list, and devices connected “illegally” will be highlighted in red. When an unknown device is detected, WiFi Guard will instantly determine its IP address and host name. This data will be displayed in an urgent message to the administrator.

Anyone can use WiFi program Guard is completely free. This network “defender” has a very simple interface and attractive settings. Even users without experience will not have any problems using the program.

To work with large wireless networks, there are a sufficient number of good multifunctional software solutions on the market that allow for comprehensive testing of WiFi networks. However, you will often find it easier to use simpler, free tools to get a quick look at the airwaves during design, deployment, or troubleshooting. We present to your attention an overview of the most interesting free programs for diagnosing WiFi networks.

In this article, we will introduce you to nine free software tools - most of them are powered by operating systems Windows, others - for macOS or Android - which will provide you with basic information about the existing WiFi signals in the coverage area: SSIDs, signal strength, channels used, MAC addresses and types of protection of a particular network. Some can detect hidden SSIDs, determine noise levels, or provide statistics about the successful and unsuccessful packets sent and received on your wireless connection. One of the solutions includes a WiFi password cracking toolkit, which will be extremely useful for finding vulnerabilities and security assessments when testing the hacking resistance of your wireless network.

Note also that most of the tools described below are free versions of commercial solutions distributed by the same vendor, but with reduced functionality.

Wireless scanner local networks Acrylic WiFi Home is a stripped-down version of the commercial solution from Tarlogic Security. Version 3.1, reviewed in this review article, attracts attention, primarily due to the detail of the wireless environment and advanced graphical capabilities for displaying collected information. The functionality of this solution includes: overview of found WiFi networks supporting 802.11 a/b/g/n/ac standards; detecting unauthorized access points and displaying connected clients; scanning and analysis of WiFi channels used by wireless networks at frequencies of 2.4 GHz and 5 GHz; plotting graphs of the received signal level and its power for WiFi access points.

WiFi scanner for Windows Acrylic WiFi Home will allow you to scan and view available wireless networks in real time, provide information about detected WiFi networks (SSID and BSSID), their type of protection and wireless devices currently connected to the network, and will also allow you to get a list WiFi passwords(installed by default by manufacturers) thanks to the built-in plugin system.

Being free product Acrylic WiFi Home 3.1 has a simple yet attractive GUI. A detailed list of SSIDs is located at the top of the application. Here, in particular, you can find: negative dBm values ​​for the Received Signal Strength Indicator (RSSI), supported 802.11 standard (including 802.11ac) by access points or WiFi routers, manufacturer name, model and MAC addresses network devices. The solution recognizes the bandwidth being used and displays all channels involved. It doesn't look for hidden SSIDs, but may show them if it detects network data indicating the presence of hidden networks. The application also has functionality for inventorying the operation of WiFi networks, allowing you to assign and save the names of detected SSIDs and / or clients (for the free version, this feature has quantitative restrictions on use).

At the bottom of the application screen, by default, visual rating information is displayed on the network characteristics of the selected SSID. There is also a graph of the signal level and power of all detected access points. When you switch to the advanced mode for displaying the status of wireless networks, you will receive two additional graphs - for the 2.4 GHz and 5 GHz bands - which simultaneously display information about the channels in use, including those combined into one “wide” channel, and signal level data.

Exporting or saving captured data is extremely inconvenient, as the software company decided to cut down this functionality excessively in the free solution: you can copy at most one line of data to the clipboard and then paste the text into a word processing document or spreadsheet. There is also a function for publishing a screenshot on Twitter.

Overall, Acrylic WiFi Home is a good software WLAN scanner, especially considering that it doesn't cost anything. It collects all the basic information about your wireless space and clearly demonstrates the obtained data, both in text and graphical form, which is perfect for simple WiFi network diagnostic tasks. The main disadvantage of this solution can be considered large problems with data export, or rather, the virtual absence of such an opportunity due to the functionality in the free solution that was limited by the manufacturer itself.

AirScout Live (Android)

Greenlee's AirScout Live app turns your Android smartphone into a convenient and portable WiFi network analyzer. AirScout Live has seven operating modes, four of which are completely free to use without any restrictions for Android devices. Commercial version, unlike free, is compatible with most desktop computers (Windows) and mobile devices(Android and iOS). With the help of basic functionality, you can quickly, mobilely and, most importantly, solve problems related to insufficient levels of WiFi signal in some places in your office or home.

AirScout live will show all the characteristics of access points detected within range: from signal strength and security protocols to equipment capabilities. It will allow you to determine the least loaded channel, measure the signal strength at each point of the WiFi network and identify places with insufficient signal strength. Helps identify sources of interference by analyzing channel usage parameters in the 2.4 GHz and 5 GHz bands. Using the program, you can select the optimal location for the location of access points to ensure the highest quality coverage of the premises with a WiFi network and configure it to maximum performance without buying additional equipment. Additionally, the AirScout app allows you to take pictures of your WiFi network and save them locally or upload them to the cloud.

AirScout Live is very easy to use and requires no additional training. The user interface looks attractive and intuitive. The first two menu items - “TD Graph” and “TD Table” - will provide you with a visual and comprehensive information about all the characteristics of access points located in the visibility zone. Access point coverage graphs will visually demonstrate to you the dependence of the signal level of each of them and the congestion of channels in the 2.4 GHz and 5 GHz bands. Extended information in tabular form about each access point (SSID, Mac address, equipment vendor, channel used, channel width, received signal level in dBm and security settings) is available in the second menu item.

The “Time Graph” item will allow you to see all the access points that your Android device has detected in the observed location, and their graph of signal level changes in dBm with a time reference. So, for example, if you are examining a network that consists of several access points, this information will help you understand what signal strength each of them will have at a given location, and how the client device will switch between them. In addition, selecting a specific access point highlights its signal strength, which helps visual perception of information.

The “Signal Strength” item will allow you to visually test the signal level for each access point over time. You can select a specific SSID and see the current, as well as the minimum and maximum signal level recorded by the device for this access point. The original interpretation of the results obtained in the form of a red-yellow-green speedometer will make it possible to clearly see whether a particular function will work in this particular place or not. For example, a stable signal level in the green zone will tell you that here you will not have problems with resource-intensive technologies such as voice over IP or streaming video in Full HD format. Being in the yellow zone will indicate that only web surfing is available. Well, the red zone will mean big problems with receiving a signal from this access point in a given location.

To use additional functions that are not available in the free version of the software without additional equipment (identifying the most common problems: suboptimal signal coverage or incorrect channel selection; identifying sources of interference, including from “non-WiFi” devices; optimizing WiFi network configurations , adjacent to 802.15.4 networks; tuning WiFi performance by comparing signal strength and usage; Ookla speed test and much more), you will need an AirScout controller or a kit that includes the controller and remote clients.

AirScout Live is an excellent application that, above all, attracts with its portability. Agree, having a tool that will always be at hand is worth a lot. The free version of the product provides you with all the necessary information you may need to quickly analyze the health of small office or home WiFi networks and identify underlying performance problems. An intuitive interface and competent graphic design of the obtained measurement results not only leave a good impression, but also help speed up the work with the application.

Cain & Abel is a multi-purpose operating room application Windows systems for password recovery and cracking, which is also equipped with tools for interception and analysis network traffic, including WiFi networks. Like its predecessor (Acrylic WiFi Home), Cain & Abel is a powerful network analyzer capable of capturing and processing most wireless network traffic.

Its graphical interface has a relatively ancient, simplified look. The toolbar (old style with icons at the top of the screen) is used to launch various utilities. Access to the main functional parts of the application is provided through window tabs.

Through the “Wireless” tab we get access to functional tools for analyzing the network traffic of WiFi networks. In addition to the usual information about SSIDs and various signal information, a list and detailed information about connected clients can also be found here. For access points and clients, Cain & Abel provides information about the number of packets detected: all packets, WEP Initialization Vector (WEP IV) and ARP requests. Any hidden SSIDs discovered from the captured packets will be displayed in the GUI. Most of the intercepted statuses and data can be exported to a simple text file.

Despite the enormous functional potential of this solution, shortcomings such as the lack of visual graphs, as well as the inability to recognize 802.11ac access points and determine wider channels, do not allow us to call Cain & Abel best choice for monitoring and analyzing WiFi networks. This solution is worth paying attention to if your tasks go far beyond simple traffic analysis. With it, you can recover Windows passwords, perform attacks to obtain lost credentials, examine VoIP data on the network, analyze packet routing, and much more. This is a truly powerful toolkit for a system administrator with broad powers.

Ekahau HeatMapper is a mapping software tool for deploying small home-level wireless networks and determining the optimal location for access point installation. This is simplified free version professional solutions from Ekahau. This software product provides the same network information as a WiFi wireless network scanner, but also generates a WiFi heat map so you can visualize signal levels. For the purposes of this review, we will focus on version 1.1.4.

The software offers the ability to create a plan or layout of the site being studied, as well as design a wireless network topology using a grid for rough orientation.

The left side of the main UI screen displays a list of wireless networks and their details, sorted by signal, channel, SSID, MAC address, and security type. This list includes basic information, but does not contain signal strength in dBm or percentage. In addition, the application does not recognize networks that support the 802.11ac standard, identifying them as 802.11n.

Using Ekahau HeatMapper, as with other mapping tools, you plot your current location on a map while you walk around a building to generate a heat map of WiFi coverage. Ekahau HeatMapper will automatically calculate the location of access points and place them on the map. Once all the data has been collected, an interactive heat map of WiFi coverage will be generated. So, for example, when you hover the cursor over the access point icon, its coverage will be separately highlighted; and when you hover your cursor over a heatmap area, a tooltip window will appear for the received signal strength indicator with a negative dBm value for that point.

According to reviews, the Ekahau HeatMapper software solution is an overly simplified WiFi mapping scanner: the manufacturers removed almost all additional functionality from the free version, making this solution a truly home version. Additionally, the only option available for exporting or saving is to simply take a screenshot of the map.

However, the Ekahau HeatMapper solution can be used for small networks or to get a basic understanding of how more professional map-based tools work.

Homedale Software Utility is a relatively simple and portable (no installation required) wireless network scanner for Windows (currently version 1.75 available) and macOS (currently available version 1.03) operating systems with an optional interface command line. In addition to displaying basic information about wireless networks and signals, this utility also supports location determination using GPS and other positioning technologies.

This utility has a simple graphical interface that resembles more of a dialog box with several tabs than a full-fledged application. The first tab, Adapters, displays a list of all network adapters, along with their IP gateways and MAC addresses.

The Access Points tab contains a lot of important information. It doesn't show the 802.11 standard for each SSID, but you will find all supported data rates, as well as all channel numbers used by each SSID at a given time, including those with larger channel widths. It also doesn't list hidden networks, but does show other network data that indicates the presence of hidden SSIDs. Also a very useful feature is the ability to save notes for individual SSIDs, which can then be included in any data export.

In the Access Point Signal Graph tab, you will find the change in negative dBm values ​​for the received signal strength metric over time for all selected SSIDs. The implementation of access to this functionality cannot be called very convenient and intuitive - the selection of wireless networks for monitoring and comparison is made by double-clicking on the desired SSID from the list of the previous “Access Points” tab.

The “Frequency of Use” tab illustrates in real time a graphical dependence of the frequencies used by each SSID (for convenience, divided into channels) and signal level values. Channel usage visualizations are displayed for the 2.4 GHz band and each subset of the 5 GHz band. The utility performs its task - visually demonstrates the occupancy of each channel - but it would be more convenient if we had the opportunity to have a single view of the 5 GHz frequency, instead of dividing it into four separate graphs.

In addition, Homedale offers excellent opportunities for both free application, to export the collected data. Thus, it supports saving the network list in a table form in CSV format, logging the results of each scan (useful if you move while scanning), and also saving an image of each graph.

Despite its very simple graphical user interface, Homedale provides more advanced functionality than you might expect. In addition, I would like to note the rather impressive, both for free program, the ability to record and export data, as well as location determination.

LizardSystems offers a free version of their WiFi Scanner software for non-commercial use that has the same features and functionality as their paid product. Currently version 3.4 of the solution is available. In addition to the WiFi scanner, this solution also offers excellent analytics and reporting functionality.

The application has a modern graphical interface, intuitive and easy to use. The Scanner tab provides a list of detected SSIDs. In addition to the standard detailed information here you will also find signal strength values ​​in both negative dBm and percentage values. It even shows the number of clients that are connected to each SSID. Also, along with the 802.11 standards specification, the solution can detect and report multiple channels used by any SSID with a larger channel width.

You can use the list of visible SSIDs to filter input based on the following parameters: signal strength, supported 802.11 standard, security types, and used frequency bands. At the bottom of the Scanner tab are graphs that you can switch between. In addition to typical graphs showing signal strength and channels used, visualizations of data rates, channel load and number of clients are also available. The bottom of the screen displays information about your current connection. In the "Advanced Information" tab you will find various data about network activity, up to the number of unprocessed packets.

The Current Connection tab displays more detailed information about the current wireless connection. Here you will access and manage the list of wireless network profiles saved in Windows 10, which can be useful because in this latest version The Windows operating system no longer provides native access to and management of this list. The Wireless Statistics tab provides graphs and statistics for various types of packets, both the physical (PHY) layer and the data link (MAC) layer, which will be useful for conducting advanced network analysis.

LizardSystems WiFi Scanner software solution offers advanced exporting and reporting capabilities. Basic functionality allows you to save a list of networks in text file. Additionally, you can generate reports summarizing the types of networks found in the scan, with all SSID data logged, any comments you added, and snapshots of the graphs. These are pretty impressive features for a freely available WiFi scanner.

In summary, LizardSystems WiFi Scanner really impresses with its functionality, including output filtering and reporting capabilities, as well as advanced information about the data packets being transmitted. It can be an important part of your go-to toolkit for maintaining and testing WiFi networks, but keep in mind that the free license is only available for personal use.

NetSpot (Windows and macOS)

NetSpot is a software solution for researching, analyzing and improving WiFi networks. The commercial version uses mapping tools for thermal visualization of coverage areas, but this is not available in the free version for home use. However, this solution is offered for both Windows and macOS operating networks. In this review article, we will look at NetSpot Free version 2.8 - a free, significantly stripped-down version of the company's paid products for home and corporate use.

The NetSpot Discover tab is a WiFi scanner. Despite the simple graphical interface, it has a modern appearance, and the network details of each SSID are displayed in bold and clearly visible. Signal levels are shown in negative dBm values ​​(current, minimum and maximum) as well as percentages. Hidden networks are not displayed in the free version, and the ability to export data is not supported (although there is such a button, it is not active).

When you click on the “Details” button at the bottom of the application window, combined graphs of signals and used channels for each WiFi range, generated for the SSID networks selected from the list, are shown. In addition, the signal information of each SSID is displayed in a table view so you can see the exact values ​​received by the application during each scan.

Overall, the free version of NetSpot does a good job of detecting WiFi networks (although it does not support working with hidden networks). But still, free solution has very limited functionality, which is eloquently evidenced by broken links to a large number of additional features - this is the inaccessibility of visualizations, the inability to use a heat map, and the lack of export.

WirelessNetView (Windows)

WirelessNetView is a small utility from NirSoft that runs in the background and monitors the activity of wireless networks around you. It is offered free of charge for personal and commercial use. This is a fairly simple WiFi scanner, available in both portable and installable form. For the purposes of this article, version 1.75 is considered.

The WirelessNetView solution's graphical user interface is not very fancy - it's just a window with a list of wireless networks. For each detected network, the following information is available: SSID, signal quality at the current time, average signal quality over the entire observation period, detection counter, authentication algorithm, information encryption algorithm, MAC address, RSSI, channel frequency, channel number, etc. .

Thus, this utility provides signal level indicators in negative dBm values, as well as in percentage terms for the last received signal and the average for the entire observation time. But it would be even better if we also had access to the average values ​​for the RSSI of a particular access point over the entire observation period. Another unique piece of available analytics that WirelessNetView offers is a measure of how often each SSID is detected, which can be useful in certain situations.

Double-clicking on any of the detected wireless networks will open a dialog box with all the information about a particular network, which can be very convenient, since your screen width is clearly not enough to view all the details in the main list. Right-clicking any network in the list allows you to save data for that specific wireless network or all detected networks to text or HTML files. The Options toolbar menu displays some options and additional functionality, such as filtering, MAC address format, and other display preferences.

Please note that this utility lacks a number of advanced features that we expect to see in modern WiFi scanners. First of all, we are talking about a graphical presentation of information, full support for the 802.11ac standard and, accordingly, recognition of all channels occupied by an access point that can use a larger channel width. However, WirelessNetView can still be useful for simple monitoring of wireless networks or small WiFi spaces, especially if you find some of the utility's unique functionality valuable.

Wireless Diagnostics (macOS)

Beginning with OS X Mountain Lion v10.8.4 and later operating systems, Apple provides a Wireless Diagnostics tool. It is more than just a WiFi scanner; it can help detect and fix WiFi connection problems. But the best thing is that it is a native toolkit included in the operating system. For this review, we'll look at the Wireless Diagnostics software solution included with macOS High Sierra (version 10.13).

To get started, press the Option key and then click the Airport/WiFi icon at the top of MacOS. You'll have more detailed information about your current WiFi connection, as well as access to the "Wireless Diagnostics" shortcut.

Opening Wireless Diagnostics will launch a wizard called "Assistant" that may ask for additional information such as the router's make and model, as well as its location. Tests will then be run to detect problems. Once verified, a summary of the results will be shown, and clicking the icon for each result will show expanded details and suggestions.

Although it's not entirely obvious, you also have more tools available to you than just the aforementioned wizard. While the wizard dialog is open, clicking the Window button at the top of the toolbar will provide access to additional utilities.

The Scan utility is a simple WiFi scanner that shows the usual data about detected wireless networks, as well as a brief description of network types and the best channels. One of its main advantages is that it shows noise levels in WiFi channels, which most of the Windows scanners presented in this article do not show. However, it would be more convenient if all channels that use specific SSIDs with a larger channel width were listed, rather than just showing the channel width and the center channel.

The "Info" utility shows the current network connection and detailed detailed information about signal characteristics. The “Logs” utility allows you to configure WiFi, EAPOL and Bluetooth diagnostic protocols. The Performance utility shows line graphs of signal and noise, signal quality and data transfer speed of the current connection. The Sniffer utility allows you to capture raw wireless packets, which can then be exported to a third-party packet sniffer.

In summary, the utilities included in the Wireless Diagnostics toolkit of the MacOS family of operating systems are truly impressive, especially when compared to the native wireless toolkit for Windows operating systems. You always have a WiFi scanner at your fingertips (which even shows you noise levels) and packet capture capabilities (with subsequent export options), and their troubleshooting "Assistant" seems really smart. However, to visualize WiFi channels, in our opinion, the channel usage graph is not enough.

In addition, to receive additional information Apple offers an excellent tour and guide to using Wireless Diagnostics.

conclusions

Each of the programs we reviewed for diagnosing WiFi networks has its own advantages and disadvantages. Moreover, all these solutions, judging by user reviews, are worthy of downloading and evaluating in action. The choice of the optimal program for each specific case will be different. So try it!

SoftPerfect WiFi Guard is simply a wonderful watchdog program for your PC. Why a watchman? Because better apps to protect your Wi-Fi wireless network from prying eyes, smartphones and laptops you won’t find. The SoftPerfect WiFi Guard utility is ideal not only for home use. If you have your own small corporate network in your office, try protecting it from unauthorized access using this program. It's much easier and more reliable than you might think!

How does SoftPerfect WiFi Guard work? If it tries to connect to the network unknown device, the utility will instantly notify you about this. If an attacker has protected his device and now it does not want to respond to ping, SoftPerfect WiFi Guard will still detect it.

That is, even if your network password is hacked or some holes appear in the encryption, this program will instantly notify you about this so that you have time to react. This way, no one will be able to steal personal data and will not use your network for their own purposes. At the same time, you can download SoftPerfect WiFi Guard at any time on our website.

The main features of SoftPerfect WiFi Guard are impressive:

• Ping absolutely all computers and network devices connected to the current network. The program displays a complete list of devices and shows which ones are active.
• Detects even those computers with firewalls that are protected and refuse to respond to ping.
• You can configure network scanning at a specific interval.
• If an unknown device has connected or is trying to connect to the network, SoftPerfect WiFi Guard instantly notifies you about it.
• Works on both Windows OS and Mac OS X and Linux.

Screenshots of the program

It is always better to call a spade a spade, so we can say with confidence that an outsider who connects to a Wi-Fi network without the knowledge of its owner is a thief. Such people should not be encouraged, but their actions should be stopped immediately.

Of course, you can diplomatically contact the “freeloader” personally and tell him not to connect to your Wi-Fi anymore, however, it’s no big secret what this will ultimately lead to.

What should cause suspicion?

As a result of a “thief” connecting to the Internet you pay for, not only the quality of data reception and transmission decreases, but also significant risks of a confidential and financial nature arise.

The owner of a wireless network should immediately be suspicious of the following signs:

1. Drop in Internet speed;
2. Even if you turn off all devices using the connection to the router, the device indicator lights continue to blink intensely.

It should be added that the WiFi owner always has access to traffic statistics, which is available to him on the official source of the Internet provider.

Sometimes even a cursory analysis of the consumed traffic volume immediately leads to the corresponding conclusions about the presence of an unauthorized connection.

What to do if traffic is stolen?

There are many software tools that allow you to quickly and effectively solve the problem of how to identify and block an unauthorized WiFi user.

But this can also be easily done using the router itself, and there is no need to download and install additional software, so first we will describe methods using the web interface of wireless equipment.

In the case when the Internet provider is, for example, Rostelecom or Beeline, as well as other popular providers who often provide routers to their subscribers, then you should also use software devices.

The principle of operation is the same for all router models, and it does not matter which manufacturer released it, for example, Netis, Netgear or another.

The essence is always the same and is as follows: the instrument control panel has tools for identifying connected devices, and, most importantly, a convenient function has been implemented that allows you to block their access.

Methods for working with various equipment models are described below. Routers have their own software programmed into them, however, due to the lack of built-in means of input and output of parameters, all control is carried out through a PC or mobile gadget connected to them.

In order to enter the device settings, you need to take into account the features of its model, since the provider does not produce its own routers, but simply sells them, purchasing them from well-established manufacturers.

Solving the problem through the web interface of routers

It is necessary to perform the following sequential steps:

For TP-Link, the steps in the settings menu are as follows:

If you are using a D-Link model, you must first open “Advanced Settings” and then, moving to the “WiFi” section, enter the “Station List”. Here you can conveniently disconnect any address with one click on “Disconnect”.

For Asus, the setup steps are as follows:

In the Huawei configurator, everything is also quite simple and comes down to sequential execution of simple actions:

In the Zyxel web configurator, the algorithm consists of the following steps:

Blocking technique

If the owner of the Wi-Fi network managed to see the list of connected devices, then blocking uninvited guests will not present any significant difficulties.

This is done using the built-in MAC address filtering feature.

In some cases, the “thief” may be particularly persistent. If the attacker changed his address and immediately re-entered the WiFi, which is possible if he is not blocked by a new complex code, you can also simply deny access to all addresses except those on the router owner’s exclusion list.

For this:

Using special applications

One of the most popular utilities is Wireless Network Watcher. It is available for free installation on the developer's official source.

The application displays all devices connected to Wi-Fi. Once launched, the program can work in the background and display messages on the monitor about connected gadgets.

Unlike the previous program, the possibility of stopping “freeloaders” from using other people’s Internet has been implemented.

The Netcut application was developed specifically for Windows PCs in 2007. Despite the outdated appearance of the interface, this program still works perfectly in the latest versions of Windows.

A free version of the application is available on the developer's website.

After installing it on your PC, you will need to complete the following steps:

1. Run the program;
2. Wait until the analysis is completed and the list of devices is displayed;
3. Select the line with the “thief’s” address and click “Cut”;
4. Ready.

If over time you need to unlock a device that has fallen out of favor with the network owner, you just need to click “ON”.

The developers of this utility also took care of people who do not have computers and created an application for Android gadgets “Pixel NetCut”. The utility is also very simple and effective to use.

Once you launch the application, you only need to perform a few steps:

The name of the next utility speaks for itself about its purpose: “Who’s On My Wifi”. Like all of the above, it is also freely distributed on the global web. Able to quickly display a list of devices connected to Wi-Fi.

Conclusion

In addition to the above software methods for identifying and blocking “violators,” preventive measures, no matter how simple they may seem, should not be neglected.

The main ones of these measures include setting a complex code to enter the wireless network, as well as changing it regularly.
