Greetings to all, shovny koristuvachs! Chi zamislyuvalis You, if anything, what is the security of your Internet? And also, How to recognize the security of the Internet and why does the speed of the Internet win? Aje buvaє so, scho we pay for one swidkіst, but in fact the providers give us more, a lot less shvidkіst and sim deceiving us.

The very security of the Internet is the main criterion, for which you choose your own tariff plan. We will talk to you in today's article about a lot of other things that are worth the security of the Internet.

Otze, V bought new computer she virishili connect yoga to the internet. For the first time, you need to choose the most suitable tariff plan. The tariff plan requires a change in the number of services (Internet connection, subscription fee, other additional services, etc.), which is expected by the provider. Companies that provide services to access the Internet are called providers or simply service providers.

At this lesson we can see:

1. Internet accessibility;

2. Lonely for the security of the Internet;

4. Causes of low Internet speed.

Would you like to get a good idea of ​​what the speed of the Internet is like? You notice that you filled the bathtub with water, obviously, turn on the faucet, and the bathtub begins to fill up with water. How quickly to fill up a bath with water, to lie down, first for everything, such parameters as: the volume of the bath (cubic meters), the diameter of the pipe and the pressure of the water (the tap is strong).

You can say the same, if you capture some kind of file from the Internet, the more secure the Internet will be, and the less you will cover the captured file, the easier it will be to capture the file. The file that needs to be occupied has its own line in bytes (KByte, MByte, GByte, TByte).

Why is the internet speedy?

The unit of the Internet speed is measured in bits per second (b/s, Kb/s, Mb/s (1Mb/s = 1024Kb/s)). 1 Byte \u003d 8 bits, it can also be said that the difference between a megabyte and a megabyte becomes 8 times. With whom it is necessary to remember that Kilobytes and Megabytes per second are denoted by the great letter, like Russian, so English(MB/s, MB/s, MB/s, MBps). Vidpovidno kіlobіti and megabіti are denoted by small letters.

Even more often, richly coristuvachivs do not correctly assign the real speed of their Internet, through the knowledge of translating more than the names of the quantities. In this hour, there are a lot of programs, which are recognized for downloading files from the Internet, in a different way, they show the speed of the download. Therefore, some programs show the speed of the charge in Kb/s, others in Mb/s. In order to correctly learn how to signify the security of the Internet, I will bring practical examples, so that I can help you master the basic rules for transferring the identity of the security of the Internet to the Internet.

1. To convert MB/s (Megabyte per second) to Mbit/s (Megabit per second), multiply the required value of MB/s (Megabyte per second) by the maximum.

For example, you want to try a movie from a torrent, with which the speed of data transfer becomes 3 MB / s (Megabytes per second), then, you need to multiply the value by 8, the result will be 24 Mb / s (Megabytes per second).

2. To convert Mbit / s (Megabit per second) to MB / s (Megabyte per second), the required value of Mbit / s (Megabit per second) should be divided into volumes.

For example, you connected to the Internet and chose a tariff plan that transfers 8 Mb/s (Megabit per second). If you are interested in a great file in a torrent, the program will show that the maximum speed is 1 MB / s. Which one needs the value of 8 Mb/s to be added to the top.

3. To convert KByte / s (Kilobyte per second) to Mbit / s (Megabit per second), multiply the value of KByte / s (Kilobyte per second) by 0.008.

For example, the speed of your downloaded file is displayed in Kb / s (kilobyte per second) and becomes 500 kb / s;

It is also important to note that online calculators are being used on the Internet at once, as they allow you to easily translate the given value into different values.

Porіvnyaєmo with water, like filling our bath. Kb / s - the speed of the water, and Kb / s - i є obsag bath. In the guidance below the table, you can see that the more secure the Internet will be, the more secure the file will be on your computer.

In other words, it seems that if we go to some kind of site, then our computer starts overpowering the water supply to the server and takes it out of the new air. Tim ourselves from this swidkistyu, for which we take away the vіdpovіdі i nazvatimemosya shvidkіstyu іnternet zadnannya.

I think that now you can be informed about the speed of the Internet and when choosing a tariff plan, choose the most distant tariff for yourself.

How to recognize the security of the Internet?

For more food, as we can see with you - why do you know the security of the Internet, or in other words, how do you check the security for help? free internet services. At the same time, there are different sites-services, which are allowed in online mode to check the security of the Internet, so you went to the site, pressed the button to check the security of the Internet and in a day you will see the security of your Internet.

For example, you can name such sites (services) 2ip.ru, speedtest.net and so on. I'll show you some of these services at a time, for the help of which you can find out the Internet security of your computer.

The first service that allows you to change the speed of the Internet connection is Yandex Internetometer. Yak you already guessed Danish service belong to Yandex. So, go for the help http://internet.yandex.ru/ and in the tab of the browser that you see, click on "Decrease security".

Through a sprat of whilin, the internetometer will check the security of your Internet connection. Then, after the completion of the re-verification of the internetometer, I can see the security of the internet.

The security check cream service allows you to assign the IP address of your computer. Security of interest and will be security of the Internet. At the butt, it becomes 1893 Kb / s (1.8 Mb / s).

Another service that allows you to determine the Internet speed of your computer is the site speedtest.net. Crim the speed of the Internet, You can find out about ping. So, go to the speedtest site, as ordered, and in the browser, click on “Start rechecking”.

After the completion of the re-verification, you will see the result of the speed of the change and the speed of the transfer. The speed of the transfer is the security of your Internet (6.19 Mb/s).

Like a bachite, the display of two different services is essentially the same as one. The real significance that is seen by different services is far from the real speed, it is impossible to say with hundreds of years' worth that this quality is really such.

A lot of information about coristuvachi for checking the speed of the Internet vicarious torrents. Adzhe, as it seems, there is no exchange for shvidkistyu on torrents (as the exchange is not installed in the torrent program itself). In order to change the speed of the Internet through a torrent, it will be enough to put a torrent file on the download, and let the client-torrent see us the speed of our Internet connection (the values ​​will be correct, as there is no exchange for the speed and speed on the server side). technical problems). You can read the report about the torrent at the article:

In my case, the speed is presented in KB / s (492.5 KB / s), so, multiplying the value by 0.008, we take the speed of Mb / s (Megabit per second), and itself 3.94 Mb / s. Price value very close to my rate plan. It is important to know that the value you choose will be approximately the same as the speed statement, but it is necessary to add the service traffic ranks (download to the server and back).

In such a rank, as if the speed of the Internet was misrepresented by you, let’s say, for a long time, it’s up to you, what is presented in your tariff plan, then you should go back to the subscriber’s account or to quiet. support.

What are the reasons for the low speed of the Internet?

And now let's take a look at the main reasons for the low speed of the Internet connection. The interest of the parties from the Internet can be even lower for various reasons (for example: the tariff plan transfers low speed of your Internet connection).

We must first say that the speed of your Internet is due to the productivity of the computer itself. As soon as an hour of work at the computer, some programs hang up, as well as the computer itself as a whole, and the speed of the Internet will not be high, so don’t be surprised at those that you have connected to a high tariff.

In one of the past lessons, I have already shown how you can prevent a computer from freezing and improve the computer's firmware, I recommend that you read the article:

An important official to ensure the necessary security of the Internet and the power to the configuration of the computer itself (RAM, video card, processor).

What do you need to pay attention to when buying a computer? You can find out .

Also, the reason for the trivial attraction of the sides from the Internet can be the attraction of the site itself with different banners, advertisements, additional scripts. Buvaє and so, that in the time of the peak, the site is expected to be richly coristuvachiv, that the server is heavily intrusive in its line, and the speed of the interest of the side is noticeably changing. Like on the server viroblyayutsya technical robots, then this is the reason for the trival of the interest of the party.

On this article - How to recognize the security of the Internet, I will conclude. The information, as it was presented in this article, I believe, helped me to improve my diet. Now you, knowing that such a security of the Internet with ease can help you with food, how to recognize the security of the Internet and turn it over for additional Internet services.

I need to indulge you with a high-speed Internet and get in touch. Good luck with the article =>

Good day! I often ask about why the speed of the Internet is the same, as it can be distorted. Really, everything is easy to do. More nuances can be seen in the current publication.

For the first time, let's marvel, in some loneliness of the world, the speed of the connection with the global net is calculated, and how practical is the severity of these figures. Marvel at the distance, be an example.

Singles for the security of the Internet with a butt

Most often, two singles of the world are spoken:

1. Kilobit per second (Kbit/s);
2. Megabit per second (Mbps).

Speaking with my simple words, what is bigger is better. Let's move on, for example, for pidrakhunkiv, for some vikoristan, this is the meaning:

• 1 Megabit (Mbit) is more than 1024 Kbit;
• 1 Megabyte (Mb) is equal to 1024 Kilobytes (Kb);
• 1 Kb more 8 Kb.

It is permissible, the speed of the connection to become 4096 Kb/s - strictly 4 Mb/s. If you want to convert to Kb and Mb, then you can convert 512 Kb / s and 0.5 Mb / s.

Let's explain on the zvichaynіy situation. It is acceptable, є file, the size of which becomes 700 MB. With a well-glanced butt of swedishness, yoga can be priced for about 23-24 hvilini. It's easy to win - 700 uploads per 0.5 Mb and then for 60 seconds.

I'll tell you that the swedish meanings are poured into the impersonal different parameters. We won’t be able to delve into professional subtleties at once, I’ll say only that in them there is a specific connection at the skin’s singing moment of the hour. That way you can change from time to time.

Calculation of the security of the Internet

Why can you beat the speed of the Internet, they marveled at the numbers of other alone wins. Now let's tell you how to reconsider the connection to the global network. However, it is necessary to know at a glance that the security of the day is divided into 2 types:

1. entrance;
2. vacation.

The first one shows the speed of transferring from the Internet to the computer of a koristuvach, a friend - now.

Vikonati perevіrka can be completed shvidko. For example, here chi here. For the possibility of carrying out the necessary tests, you can find out on other sites, prote resurfacing options, I guess, quite enough.

It’s not strange to be surprised, as if with a new skin change, the parameters are usually changed one kind of one. Ring out, it's a normal sight. Why is it so obvious, explaining more.

Vіddalena robot and the speed of the Internet

Vіddalena robot a designer, a specialist in the production of videos and for other kinds of work may be due to the need for transmission, zavantazhennya great obsagiv danikh. As you understand, here are important swedishness merezhnogo z'єdnannya shards of stench are indicated at the hour of the chanting of the chant.

How do you think it is possible to get a normal income from the Merezha? I will say this: after the fact, for beginners, great prospects emerge, so forget about the myth and seriously go back to the beginning, and then to work. Before the speech, I will once again rejoice - the training for the most professional directives is three years, not 5-10 years, but a sprat of ten months.

For the cob varto, get to know about the required professions of work in the field. You can find out about them at cost-free online marathon.

Would you like to know more about computer literacy or remote work? On this blog, the mass has already been published brown information. I am preparing new materials. For the bazhannya for the podia on the blizzard you can walk in social measures. Zrobiv thematic groups, sides.

You can also sign up for a free quote on email, having created a theme for you. Until the sound.

With a fall in speed, the simplest sides can be zavantazhuvatisya with whiplash, and for a film in HD-quality, it is necessary from a few years to a few days. Naturally, you want to fix the problem, moreover, it’s more likely, but it’s necessary to change it a bit, because it’s out of the blue.

What kind of loners win the speed of the Internet?

The throughput of the building of the Internet connection (tobto, in the water, the speed of the Internet) is the amount of data that the computer accepts or transmits for one hour (sound for one second).

The rich koristuvachs call out those who at the same time win two different ones in the world: beat and beat.

• 1 byte = 8 bits;
• 1 kilobyte (Kb) = 8 kilobyte (Kb) = 1024 bytes;
• 1 megabyte (Mb) = 8 megabit (Mb) = 1024 kilobytes;
• 1 gigabyte (GB) = 8 gigabytes (GB) = 1024 megabytes.

Folding is blamed on the fact that the speed of the Internet channel will sound in bits, then the same way the expansion of files will sound in bytes. It really means that the provider is offering you an Internet connection with a speed of 100 Mbps, a file with a size of 100 megabytes and you will capture it in 8 seconds.

IMPORTANT: Tariffs indicate the very security, what to enter (for the transfer of data), as a rule, will be less. Vtіm, great vihіdna shvidkіst seldom needed.

It is also necessary to be aware that in the application you should go about the ideal mind - in the initial situation, the speed will be a little lower, the lower is declared (it is related to the concerns of a specific web server, the camp of the transmission lines is just that).

How to win the security of the day?

As you commemorated the fall of speed, it would be easier to speed up one of the online services from the re-verification of the Internet. Pratsiyuyut such a site is even simpler: send your computer a package of data of the song oblige and check the hour you need to do it. Tse shvydky, bezpechny that exact way to determine the real shvidkіst z'ednannya z merezhey.

Before Tim, how to win the security, it is necessary:

1. Check your computer for viruses;
2. Turn on all managers of zavantazhen, torrents, firewalls and other programs, like vicorous meshes;
3. Shut down all sites that actively drive traffic (music, movies, games, etc.);
4. If you have up to one Internet channel connected to a few add-ons (for example, through a router), turn off everything, except for one. It is ideal to secure a direct connection of the computer with the Internet (not through a router).

If so, you can change the security of the day. To obtain accurate results, we recommend 3-4 checks on decal services - the average value and will be closest to reality. You can check out these sites:

One of the most popular services of this kind. Automatically selects your locale, indicating the most appropriate for accurate testing of the server, freezing the speed of receiving and transmitting data, as well as ping (the hour of the server's wake-up call, which is expected from your computer). Display the result in megabytes (to remove the download speed in megabytes, you need to divide by 8, and you can reverse the speed declared by the provider).

Simple i manual service, what you take to the respect of your provider and the swedkity declared by him. Also, take notes about providers, based on tests carried out by other coristuvachs - it can be corny. The result, like the previous one, is seen in megabits.

One more disgraceful site, which is a victorious one when you win the data about your special knowledge, but here, on the vіdmіnu vіd forward services, I can tell you to do yoga manually. The result is the same for megabytes.

Having equalized the results, otrimani on all sites, you can take the most adequate to the real standard of the speeches given.

Alternative method: re-verification of the Internet for other torrents

If you are a torrent client, then you can use the speed of the Internet for help. For whom just choose a torrent great kіlkistyu distributors, put yoga on the front and check if the recipient reaches the top mark. Obviously, in this case, you also need to avoid everything that can make the channel (anti-rus, online music, etc.), but this way gives one of the best results.

What can be added to the speed of the day?

Reasons for lowering the speed of connection to the Internet may be a little. The main one is the problems with the provider . As a rule, the very availability of the Internet can be the main contribution to the rate. As if the permit of your billing is not valid, it appears that the provider is simply deceiving you, making you cry too much. Ale before tim yak call in service center, it is recommended to use real swidk_st work and merezhі - with such gifts, your application will be more primed and better for everything, її to look at it better.

Also warto remembrance about those who did not fall in swedkost pov'yazane with the provider's robot. Vono can buti viklikane:

• Viruses. Deyakі see shkіdlyvogo software can vikoristovuvat your Internet-z'ednannya for their own purposes - for example, to spread spam;
• Antivirus robot. Either other programs, such as victorious Internet, or interleave the capacity of the channel (management, vanity, torrent, Windows update or other PZ then);
• Poshkodzhennyam cables at the boundaries of the apartment. Provid can fray the door, wear thinly;
• Web resource engagement. The site, which you are trying to access, may be revantaged by a great number of requests. Also, on the server, you can have a piece of exchanged security - you need to shy away in order to escape the total inaccessibility of the side on servers with great ambitions;
• Wrong driver. For example, if you use a USB modem, and installed old drivers for a new one - you can bring it down to speed.

Everything can be added to the speed of connection to the Internet. Before that, how to call the provider, it is recommended:

1. How do you properly view the site try to go to other resources. Check three or five sides, maybe the problem is with a specific site;
2. Yakshko swidkіst "asked" equally, on all resources, try turning on all the extensions, except for one (not the one on which the problem was revealed - for example, if you noticed a drop in security when surfing from a computer, use your smartphone) and turn the robot over to the Internet from a new one. Everything is wrong here, which means that the problem is related to a specific computer - there are no viruses, drivers chi software security(for example, richly koristuvachіv zabuvayut vmknuti managers zavantazhen);
3. How the problem is saved on all outbuildings, turn over the cables at the borders of your apartment: they don’t bend the wires, they don’t twist the doors, etc. Give special respect to the plugs - as they have broken utrimuvach, maybe the problem is in cioma;
4. Everything is safe with cables, call the provider's tech support, resurrect what you've done, and get them rechecked and I'll be on the line. Nayimovіrnіshe, they have a problem.

Don't be tempted suspicious files, do not hide behind unprotected Wi-Fi fringes, lay cables behind skirting boards or cable channels, and, as you have chosen mining provider, your Internet will be amazing!

In some loneliness, the security of the Internet is vibrating

The technical specifications of the extensions and contracts for the service of communication with the Internet provider include units of Kilobity per second and, as a rule, Megabits per second (Kb/s; Kb/s; Kb/s; Kbps, Mb/s; Mb/ with; Mb/s; Mbps - the letter "b" is small). Numbers of loners vimir є zagaloviznami in telecommunications and they vimіryuyut smugi transmission outbuildings, ports, interfaces and channels zv'yazku. Zvichayny coristuvach And Internet providers should rather not use such a specialization term, naming it "Internet security" or "Swidth security".

A lot of programs of the server (torrent clients, programs-vantages, Internet browsers) display the speed of data transfer in other units, which are even similar to Kilobits per second and Megabits per second, but the same other units are Kilobytes and Megabytes per second. Qi values ​​​​often stray among themselves, shards of stench may be written similarly.

Kilobytes per second (for which the speed of data transfer is assumed by the programs of the coristuvacha) it is accepted to mean KBytes / s, KB / s, KB / s or KBps.

Megabytes per second - MB/s, MB/s, MB/s or MBps.

Kilobytes and Megabytes per second are always written with great letter"B" as in English, and in Russian spelling: MB / s, MB / s, MB / s, MBps.

In one Byte, there are 8 bits, so, Megabytes per Megabyte (Yak and Kilobyte per Kilobita) at 8 times.

In order to translate "Megabytes per second" to "Megabytes per second", you need to multiply by the highest value, expressed in MB / s (Megabytes per second).

For example, if a browser or a torrent client changes the speed of data transfer, equal to 3 MB / s (Megabytes per second), then in Megabits it will be larger - 24 Mb / s (Megabytes per second).

To translate from “Megabits per second” to “Megabytes per second”, it is necessary to split the value, expressed in Megabits per second, by weight.

For example, if the provider's tariff plan transmits a large amount of bandwidth, which is 8 Mb/s (Megabit per second), then when a torrent is downloaded to the computer, the client program displays the maximum value of 1 Mb/s (as there is no border on the side of the server and there is no change).

How to protest the speed of the Internet on-line?

In order to protest the width of the smuga flow, you can speed up one of cost-free resources vimiryuvannya speed to the Internet: Speedtest.net or 2ip.ru.

Offending sites vimiryuyut the width of the smuga bandwidth of the server, which can be selected to the computer, on which the swidkіst is viimiryuєєє. Since it is possible for a channel to communicate from a few hundreds of meters to a few thousand kilometers, it is recommended to choose the nearest server in the territory (if you want, you can be very busy). Testing is more likely to be carried out at the hour when the activity of the client is less than the provider (for example, early or late at night). The accuracy of the air traffic control with the Internet is not ideal due to a large number of different factors, which greatly affect the throughput of the building, but as a whole, the date of notification of the real security of the Internet connection.

The Internet provider provides the skin subscriber with a bandwidth for access to the Internet according to the subscriber's tariff plan (provider "Urizaє" speed limit according to the tariff plan). However, a lot of Internet browsers, as well as the mastery of downloading files, torrent clients, display the bandwidth of the connection channel not in megabits per second, but in megabytes per second, and through this often blame the swindler.

We protest against the security of the Internet connection with the use of the speedtest.net resource. It is necessary to press the button "BEGIN TEST recommended server".

The resource automatically picks up the nearest server and checks the Internet security more often. The result of the test will be the capacity of the channel from the provider to the subscriber (DOWNLOAD SPEED) and the capacity of the channel from the subscriber to the provider (UPLOAD SPEED), which will be displayed in Megabits per second.

The speed through the router is “not the same”, the router is “lower” the speed

Most of the time, after the router's attachment, its connection and adjustment, the coristuvachs are stuck with the problem that the speed of the Internet connection has become lower, lower to the router's attachment. Especially often this problem is focused on high-speed internet tariffs.

For example, for the obviousness of the tariff plan, which transmits “Internet connection speed” at 100 Mb / s, that when connected to the cable of the provider “without intermediary” mesh payment computer, internet speed according to the tariff plan:

When the provider's cable is connected to the WAN port of the router, and the computer - to LAN port, In most cases, you can reduce the throughput rate (otherwise, as they say, “the router is less than the speed of the tariff plan”):

It’s more logical to admit that in this scheme the problem is in the router itself and the speed of the router does not match the speed of the tariff plan. However, in order to connect to a larger “more advanced” tariff plan (for example, 50 Mb/s), you can note that the router is not less than the speed and “speed of the Internet” should be assigned to the tariff plan:

Among the engineers, the terminology “router is less than speed” or “router speed” is not accepted - call for the terms “WAN-LAN routing speed”, “WAN-LAN switching speed”, or “WAN-LAN bandwidth”.

The capacity of the WAN-LAN is measured in Megabits per second (Mbps) and is based on the productivity of the router. For the speed of WAN-LAN switching and for the productivity of the router as a whole, it depends on the hardware equipment of the router (H / W - type English "Hardware", indicated on the sticker, which I will attach to the bottom) - this model i clock frequency router processor, obsyag operational memory, the model of the switch (a card inserted into the router), standard and model WiFi radio module (points WiFi access), vbudovanoy at the router. The Crimean hardware version of the add-on (H / W) played the role of WAN-LAN routing security, the version of the installed firmware (“firmware”) installed on the router. It is recommended that you update the firmware version as soon as possible.

After “flashing” or, speaking professionally, after updating the firmware to the recommended firmware version, the stability of the router’s work may improve, the level of optimization will be added for work in the networks of Russian providers, as well as the throughput of WAN-LAN.

Varto means that WAN-LAN switching security is not only in the hardware version of the add-on (H / W) and the firmware version, but also in the connection protocol to the provider.

Biggest high speed WAN-LAN routing is reached on connection protocols DHCP and Static IP, low - when selected by the technology provider VPN and yakscho vykoristovuєtsya protocol PPTP - nainizhcha.

WiFi security

A lot of coristuvachiv, who have connected to some kind of Wi-Fi network, do not be satisfied with the security of the day. Feeding is more complicated and requires a detailed look.

a. Real Wi-Fi technologies

This is how food looks, which is often put on given topics:

“I have a tariff plan that transmits 50 Mb/s speed - why go out more than 20?”

"Why is it written on the box 54 Mb / s, and the program-client, when the torrent is downloaded, displays a maximum of 2.5 Mb / s (which is 20 Mb / s)?"

"Why is it written on the box 150 Mb / s, and the program-client shows 2.5 - 6 Mb / s when the torrent is downloaded (it is 20 - 48 Mb / s)?"

"Why is it written on the box 300 Mb / s, and the program-client shows 2.5 - 12 Mb / s when the torrent is downloaded (it is 20 - 96 Mb / s)?"

On the boxes and specifications to the outbuildings, it is theoretically assigned the maximum throughput capacity for the ideal minds of that other Wi-Fi standard (in fact, for a vacuum).

In real minds, the throughput of buildings and the area of ​​​​the zone covered by the measure lie in the crossings, created by other outbuildings, the level of coverage of the WiFi lines, the visibility of the crossings (and materials, from such stench prepared) and other factors.

A lot of client utilities, which are supplied by the compilers together with WiFi adapters, as well as utilities operating system Windows, when Wi-Fi is connected, they show the “theoretical” bandwidth itself, and not the real speed of data transmission, introducing coristuvachiv into Oman.

As shown by the test results, the maximum real throughput is about 3 times lower than the one specified in the specifications before the addition or before the IEEE 802.11 standard (Wi-Fi technology standards):

b. WLAN-WLAN. Wi-Fi availability (free of charge)

All current and current Wi-Fi standards for today work in a similar rank.

At a certain moment, Wi-Fi is more active (access point or router) only works with one client (WiFi-adapter) with the help of WiFi network, moreover, all attachments take away special service information from that, what time will the data transmission radio channel be reserved. Transmission is allowed in full duplex mode. by request - active Wi-Fi access to the client adapter, later on and so on. A one-hour "parallel" transmission process (duplex) is not possible with Wi-Fi technology.

In this way, the speed of exchange of data between two clients (width of WLAN-WLAN switching) of one Wi-Fi network, created by one extension (access point or router), will be (in an ideal situation) two and more times lower (lay down in the air), lower is the maximum real speed of transmission for all measures.

Butt:

Two computers WiFi adapter up to one IEEE 802.11g Wi-Fi router is connected to the IEEE 802.11g standard. Offended computers are located on small vіdstanі router type. The whole network can reach the maximum theoretical throughput of 54 Mb/s (which is written in the specifications of the outbuildings), the real speed of data exchange cannot be exceeded by 24 Mb/s.

But if Wi-Fi technology is based on full duplex transmission of data, then the Wi-Fi radio module must be connected between two clients (Wi-Fi adapters) two times more often, lower at the same time, yakby client is one. Obviously, the speed of data transmission between two adapters will be two lower, the lower maximum is real for one client. AT this butt the maximum real speed of data exchange for skin computers is 12 Mbit/s. Guess what about transferring data from one computer to another through a router with wifi connection (WLAN-WLAN).

Depending on the distance between the client of the network and the access point or the router, it will change "theoretical" and, as a result, "real" speed of data transmission via WiFi. Let's guess, it's about 3 times less than the "theoretical".

Tse vіdbuєtsya through those who are active WiFi, working in half-duplex mode, at the same time with adapters change the parameters of the signal (modulation type, speed of short-circuit coding, etc.)

When the client is aware of the area, the coverage area is “theoretical” throughput building 54 Mb/s, the maximum real speed is 24 Mb/s. When the client is moved to a distance of 50 meters in the minds of direct optical visibility (without a jump and a jump), we get 2 Mbit/s. A similar effect can also be caused by a jump at a seemingly solid load-bearing wall or a massive metal structure - you can change it at a distance of 10-15 meters, and beyond the jump.

with. IEEE 802.11n router, IEEE 802.11g adapter

Let's look at the butt, if Wi-Fi Merezha I create a Wi-Fi router according to the IEEE 802.11n standard (150 Mb/s). A laptop with a Wi-Fi adapter to the IEEE 802.11n standard (300 Mb/s) and a stationary computer with a Wi-Fi adapter to the IEEE 802.11g standard (54 Mb/s) are connected to the router:

In this case, the entire network can have a maximum “theoretical” speed of 150 Mb/s, but only a few of them are based on Wi-Fi routers according to the IEEE 802.11n standard, 150 Mb/s. The maximum real Wi-Fi speed is 50 Mb/s. Skills of all WiFi standards that work on one frequency range, wrapped in sum one by one, then you can connect to such a measure with Help WiFi adapter to the IEEE 802.11g standard, 54 Mb/s. With this, the maximum real speed is not to exceed 24 Mbit / s. When connected to this laptop router, wifi adapter standard IEEE 802.11n (300 Mb/s), client utilities can display the value of the maximum "theoretical" speed of 150 Mb/s, (the boundary is created by the attachment to the IEEE 802.11n standard, 150 Mb/s), and the axis of the maximum speed will not be real 50 Mbps. In this scheme, the WiFi router will work with a client adapter to the IEEE 802.11g standard on real speed, which does not exceed 24 Mb/s, and with an adapter to the IEEE 802.11n standard on real speed, which does not exceed 50 Mb/s. Here you need to guess that WiFi technology is a full-duplex call and an access point (or a router) can only work with one client of the network, moreover, the client decides to “notify” about that hour, for which radio channel is reserved for transmitting data.

d. WiFi speed through a router. WAN-WLAN

How to go about the connection Wi-Fi connection to the Wi-Fi router, then the speed of the torrent interest may appear lower, lower those values, which would be higher.

These values ​​cannot override WAN-LAN switching speed, but these values ​​are the main characteristic of the router's productivity.

In this way, as in the specifications (on the box) I will add the speed of data transfer via Wi-Fi up to 300 Mb/s, and the WAN-LAN parameter for this model, the hardware version, the firmware version, and also the type of connection protocol 24 Mb/s, the speed of data transmission over Wi-Fi (for example, when a torrent is involved) cannot exceed the value of 3 Mb/s (24 Mb/s) for any reason. This parameter can be called WAN-WLAN, which can be found directly in the WAN-LAN routing security, in the version of the firmware (“firmware”) installed on the Wi-Fi router, Wi-Fi radio module (points WiFi access, budded into wifi router), as well as the characteristics of the Wi-Fi adapter, yoga drivers, remoteness of the router, noise level of the radio and other factors.
