How to use the wifi analyzer program. WiFi Analyzer – Wi-Fi network status analyzer

Sometimes in Everyday life, at using Wi-Fi networks, the most stable access point that shows best coverage, does not give the best stable internet. To easily identify wi-fi points access that provides a stable Internet, without any interference - you need a wi-fi analyzer, which will be discussed in this article.

What is a wifi analyzer

wifi analyzer- a program or device that scans and analyzes the network; as Captain Obvious tells us. The goals and implementation of such an analysis may differ greatly from searching for a cleaner channel to Aircrack-ng methods, which is highly advisable to take into account when searching wifi scanner. However, when talking about an analyzer, they mean a tool for constructing a coverage map, analyzing channel distribution, analyzing interference and signal level, excluding traffic analysis tools like Wireshark, Aircrack, tcpdump; after all, they are in a slightly different direction, although they can also analyze interference if ask.

To put it very simply, a wifi analyzer is a program to see why Wi-Fi doesn’t work.

This class of instruments is needed to observe the mutual influence of radio devices in the centimeter range, which is any equipment capable of wi-fi, or speaking in simple language in order to see in real time not only who is to blame, but also what to do, to restore a stable connection in the sense of where and how to go, yeah, a kind of Peter Pig tractor.

Wi-Fi analysis is common and necessary task when setting up, diagnosing, restoring and hacking a network. Naturally, depending on the task, aspects of the analysis are different; if during setup and diagnostics the physical properties of the channel (frequency, influence of fields, channel occupancy) are more interesting, then when hacking more attention is paid to logic (protection, encryption, etc.).

The task is so important that for devices like the Ubiquiti NanoStation, the release of such analysis is not a feature, but a necessity.

Yes, and endure one megabit rushing on your favorite tablet, when you can take a couple of steps across the room to five stripes... in order to know where to step, analysis is exactly what is needed.
The stability of the connection depends on many difficult-to-calculate factors: relative position devices, the influence of close frequencies and even surface conditions. All this is practically impossible to calculate, but you can look at it in real time and select the frequency and position in which the negative impact is minimal. Because the speed of the connection depends on the stability of the connection.

Wifi analyzer programs

There are countless software implementations of analyzers. Both well-known software writers and specialized companies were noted here, some of which are, in general, hardware manufacturers like the above-mentioned Ubiquiti with their AirView. All programs differ slightly in interface and visualization method, they do approximately the same thing and even in the same way.

Some differences are dictated by the purpose of the crawl, for example, TamoGraph Site Survey is focused on placement WiFi devices by area; InSSIDer - for connection analysis available networks within the permitted ranges; and AirView exists to make life easier for the Ubiquiti customizer on and off range. Nevertheless, the most popular of the entire family is the Wi-Fi analyzer, represented by utilities for Android and Windows devices, because “I’m an Android, I need the Internet and a power outlet.” The program allows you to find a place where no one and nothing interferes; you can simply master and use it, while being sufficient for home use.

Example of Wi-Fi network analysis

Any Analysis is meaningless without a goal. This is such an abstract thought. The goal of the first example will be to restore the channel width between Vasya and Petya. The channel is configured on Ubiquiti equipment and has only two antennas for simplicity. Having discovered a drop in speed, Vasya goes to 192.168.1.20 and sees there, say, “transmit ccq 50%”. Cursing at the slow connection, Vasya downloads JAWA and finally he presses the big blue Launch AirView button. From this moment the analysis actually begins, which, by the way, needs to be allowed to run for about 10 minutes to accumulate statistics.


Most analyzers display information in the form of graphs; there are many of them, but usually they duplicate each other to one degree or another. Vasya has three of them - short-term (power) displays changes in the last minutes of work, long-term (power) displays the scale from the moment the scan was started, and long-term (energy).

Having recalculated the peaks on the “Waveform View” graph (long-term graph of power changes), Vasya not only sees that some device has appeared nearby in frequency, but also in depth of blue color detects which frequencies you can change the channel to.
The second task for the example will be to find a wider channel for Android. We launch the Wi-Fi analyzer, look at the channel rating for the point on the “channel rating” tab, get the numbers free channels. Somehow the example didn't come out. Let's take for example the problem of finding more powerful signal points. We launch the Wi-Fi analyzer, turn on the meter and see how the readings change when we walk around the room; by the way, if the device data is linked to coordinates, we will get a coverage map in the process.

Wifi analyzer for android

A portable device used in a difficult radio environment must have the means to analyze the surrounding mayhem, it simply must. By typing Wifi analyzer, we get a list of 10 positions, similar functionality and implementation, well, I told you - the place is good.

Having chosen a program that is convenient for you personally, sometimes you don’t understand how you lived before installing it. Evaluate the network, find the optimal location, and due to the wave size wifi connection depends on the position and orientation of the device. Yes, in the end, choosing a connection point from among the possible ones is also an analysis hardwired into the phone’s carrier.

Wifi analyzer for Windows

All thoughts about portable device in force, only in the store there is less choice, prices are higher, although there is a Wi-Fi analyzer and it’s even free. On the Internet you can find InSSIDer and many, many others. The TamoGraph Site Survey mentioned above is also from this sandbox.

If you have Wi-Fi on board, you should also have a Wi-Fi analyzer. Elders say that even by removing it for the sake of free space, you still have to install it again and again.

Don’t get your hopes up, this is just a utility for “looking with your eyes”, by seeing and correcting the channel frequency, the position of the device and the antenna, you can have a more stable contact for more high speed torrents, especially if you move the welder away from the antenna.

Wi-Fi Analyzer includes three tabs namely Connected, Analysis and Networks. Connected provides information about the current WiFi connection. It displays a graphic of connection quality based on link speed and signal strength in negative dBm at the top of the window. Additionally, there are icons that show bad speeds links, weak channel, poor connection, no internet connection and unsecured connections.

The Analysis page allows you to make changes to improve the strength of the connection. It provides access to channel charts and ratings, allows you to switch between channels, and allows you to switch between frequency bands. It also provides full access to setting graphics colors and SSID/MAC. In addition, it is possible to filter the SSIDs shown in the graph according to signal bands, frequency band, overlap, WiFi method and network type.

The Network tab contains a list of all available SSIDs. It allows you to filter available connections according to their name and signal.


Today, the Internet is filled with mentions of the program Wi-Fi Analyzer. Many people use it on their phones. But regular user does not understand what kind of graphs are provided on the smartphone, and what these symbols are.
Therefore, it is best to understand the essence of the program, its purpose and the possibility of operation on Windows.

1. Why do you need such software?

Without going into too much detail, let's just say that Wi-Fi Analyzer appeared as a result of the emergence of free and public networks without passwords, but with limited speed.
Under the concept " limited“, this is precisely how the speed is hidden, which does not allow access to the Internet, in fact, for searching for information and spending time on social media. Networks.

Finding a wireless network without a password is not a problem, but finding one that would issue normal speed– it’s already more difficult.
It doesn’t even matter how close the source of this network is - you can be close to the router, but the signal will still be very low.


And the reason for the restrictions is the overload of the channels used, that is, a lot of users are connected to the network at once. The router cannot provide each user with sufficient speed, which is why restrictions appear.

Especially used for such situations WiFi Analyzer, which is able to analyze the available networks to determine which one is better and less loaded. If one is identified, its speed will be much higher, and there will be no restrictions at all.

2. Where can I download the provided software?

Initially it was released specifically for users Android platform, and you can easily find it in Google Play Market .
The page below shows what the Analyzer should look like.


On computer Wifi Analyzer can also be installed. This is done for free.


You can use the program on a PC only with availability of Windows 10, early versions are not supported.

3. How to use the program

On a phone, understanding the interface is not so difficult, because everything is transparent. Just launch the application.
After launch, all wireless networks will be scanned, and later a graph will be generated as below:


Computer graphics


All available networks are listed here in the form of parabolas. Ordinate – signal strength data. In general, the program is not difficult to understand.

4. Analogs of Wi-Fi Analyzer

A fair decision for a free application.

One of most interesting programs for analysis wifi works considered a “wifi analyzer” for windows.

With its advent, the task of finding channels and problems with them has become much easier.

And today we will look at why such an analyzer is needed and how to use it.

wifi analyzer – what is it?

The analyzer is a program that allows you to scan available networks and analyze the availability of the Internet. Its main task is:

  • analyze channel distribution;
  • analyze the signal quality;
  • carry out interference analysis;
  • issue a report bypassing analysis tools such as Aircrack.

Similar ones work in a slightly different direction, although they know how to conduct analysis.

You can download the application for free using the play market.

What is wifi analyzer used for?

There are a number of programs that offer work on Wi-Fi signal analysis. great amount. The difference between them is not fundamental.

Somewhere the interface changes a little, somewhere, some additional function present. But the results of everyone’s work are approximately the same - the same tables with conclusions.

Today we will look at a completely new application that can easily make working with wifi easier. It is used for computers and Android phones.

Let's say you installed a router to distribute Wi-Fi in your home. It does not always happen that the settings are carried out efficiently the first time and the signal is received perfectly.

What is this connected with? The neighbors also have Internet, they also have a router and there are several media that can be connected to it.

These are the reason for your troubles with the signal. Simply interference caused by such a device.

The real find is that routers can work not on one channel, but use several of them. This is what an analyzer is required for.

It will help you decide on the most suitable channel that will not respond to extraneous interference.

Advice!

If you have a router in your home, be sure to download a free one or purchase a paid analyzer. You shouldn’t hope that the interference will go away on its own, and you definitely shouldn’t be content with little. Even if, after using the application, you deleted it, for example, to save space. You still have to contact him anyway.

Wi-Fi analyzer - a miracle program

By spending just a few seconds of your time, the user can easily get all existing information about the fullness of the network and the quality of the received signal.

After checking, the user will have access to two tabs. The first contains data on the quality of the wifi channel.

This window will help you easily decide which of them would be most appropriate to join.

The second tab presents information for each channel individually. With its help, you will receive information about how much the option you are interested in is loaded.

Both pages are presented in table form. All networks are marked with different colors.

To the left of it are written all the found connection options.

On the right top corner The program settings icon is located.

Advantages of the application and reviews about it

All reviews that were found on the Internet about this application are only positive.

Some users who have installed it on their phone boast that they no longer need to run through the streets looking for free Wi-Fi.

Advantages:

  • The great advantage of this program is that in a passive state it takes up practically no space;
  • for it to detect a signal, even its weak manifestation is sufficient;
  • there is a sensor to determine its strength;

  • can be turned on sound accompaniment. The better the command, the louder its alert sound will sound;
  • the application is free and accessible to anyone;
  • provides advisory advice on solving problems that have arisen;
  • automatically detects the existence of illegal devices and the presence of network vulnerabilities.

Where can I download the program from?

The Wi-Fi analyzer is provided free of charge, and finding it on the Internet is not difficult.

1 For Android meringue phones it can be found in Google Play. This is the simplest option. It is very easy to do. Dial in search bar a request like “download the Wi-Fi analyzer program from Google Play” and the required results will open to you. Follow the link provided by the system. In the application, next to the program we are interested in, there is only one “download” button. So it's impossible to make a mistake here. Click on it and wait for the results. After downloading, follow the system’s recommendations and install the application on your storage device without any problems.

2 On Windows 10, the official download source is the Microsoft website. It's free.

A feature or even a problem for this method is that for a successful result when downloading, you must have Windows at least version ten. If she is not like that, but the application is necessary. You'll have to make an update. If this is not done, downloading will simply be impossible.

Of course, you can install some alternative, for example, inSSIDer (which is paid), or Acrylic WiFi Professional. This is the user's choice.

When you run a network check on your computer, a message will be displayed that will tell you which one is the best option for this area. It looks like this:

On the screen of an Android-based phone, the information is presented in approximately the same form.

The utility file analyzer is designed for installation on Windows tenth series release. Having a different version on your computer, tablet or laptop software, installation will not be possible.

If you really need it this application, you will need to update for Windows or use one of the analogue programs.

Wifi Analyzer for Windows 10 on your computer looks like this.

– this is an indicator of the sensitivity of the receiver; this indicator reflects the most weak level signal at which Wi-Fi operation is possible. For normal functioning the value of this section must be no less than 85 dBm. This indicator is quite enough for the device to work correctly.

– quality of the signal itself;

– network settings;

– mas – address of this network.

Below the scale there is a row of signs that indicate the signal level:

  • means that the supply is weak;
  • you didn't choose the best one the best option among channels;
  • the line used does not have access to the Internet;
  • The Internet is not secure.

Very a convenient thing Some computers have a BSSID. Translated from English, this is a unique number that is assigned wireless channel Internet.

If such a function is present on your computer, it becomes possible to configure several access points at once.

One SSID can contain up to four BSSIDs.

What do you need to choose the best channel?

To make such settings, you need to go to the program tab called “Analyze”. Quality indicators of different types of channels will be displayed here.

The designations are deciphered as follows:

  • Wi-Fi indicators different users who live in the nearby range.
  • The force with which the apparatus of each of them works.
  • The channels themselves.

Based on the data in such a table, it is difficult to understand where the most a large number of access points, and choose the best option.

But this is not the most understandable option for ordinary people. It will be much more convenient if you enable the SSID parameter.

Then each line is signed with a specific name, which makes working with it easier.

The application is very convenient in that it not only carries out analysis, but also displays the result in the form of a table with a rating of channels that the best way suitable for your device.

What to do if the signal quality has not improved after the settings?

If after all the parameters are set, and the supplied Internet still leaves much to be desired, you need to check the following points:

  • Try placing your router away from the wall. This will help remove the interference that comes from other people's devices. Moreover, these interruptions do not necessarily come from another router. They can be caused by any technique.
  • Move the device around the apartment until it is detected best place with the highest quality signal and, accordingly, Wi-Fi speed.

Analyzer for Android

After downloading the program, there are no problems with it. To get started, just launch it. An investigation will begin available options networks and displaying the results on the screen.

This utility is for mobile phone most understandable and acceptable. Another advantage is that it requires virtually no free memory space.

After the analysis, information will appear on how actively this or that network is used in a given territory.

How often does the router operate? This entire history will be displayed in the “properties” and “channels” tabs.

If your settings are similar to the example, this means that the phone you are using is not blocked by any of the available networks. After all, they practically do not intersect with each other.

You can also find out information about how strong a particular signal is.

To do this, go to the “Properties” tab “Channels”. The performance rating will be displayed as stars.

Although such an application will not take up much space in the phone’s memory, after the test is completed, you can simply delete it and, if necessary, download it again. It does not take a lot of time.

On the phone version, there is also a tab with a speedometer, which is responsible for the signal frequency. This feature is very convenient.

To choose the best quality, the user needs to move around the area and pay attention to the arrow indicators.

When she is in her highest place, your search work is done.

Same as in the version for personal computer, you can enable sound for this page.

Then, as the quality increases, the sound output from the device will also increase.
