How to increase wifi download speed. How to increase the speed of Wi-Fi (Wi-Fi) connection

The frequency range for Wi-Fi is divided into 12 channels (in some countries there are 13 or even 14). Therefore, when several devices work on the same channel, they begin to interfere with each other, which leads to a mutual decrease in the speed and stability of communication. The matter is further complicated by the fact that, broadcasting on its channel, the router actually captures two more channels on the left and two channels on the right. Your task is to configure your router to work in the most free range. It is not difficult to do this.

1. Download and install the program. It will help us identify free channels in your environment. The program is free and works on all versions of Windows.

2. Run inSSlDer. After a short scan, you will see something like this:

Here we are primarily interested in the numbers of channels occupied by competitors, as well as the range overlap map. You need to know which channel is free. Ideally, your new range should have very little overlap with your neighbors' networks. In my case, as you can see, it is quite difficult.

3. Open the router settings in the browser and change the channel. Usually this is enough to enter into the address bar 192.168.1.1 .

If you have a different address, then this can be easily found out. Press the key combination Win + R, in the window that appears, enter the command cmd. A terminal window opens where you need to enter the command ipconfig. Here is the value of the "Main Gateway" parameter - this is exactly what we need.

4. In the control panel, find the option to change channels. Usually it is located in the network settings section (Wireless Settings). Some routers have an "Auto" option that allows them to search for free channels on their own. For everyone else, it is recommended to set this parameter manually, specifying the channel that you discovered using inSSlDer.

5. Reboot the router and reconnect your computer to the network for the settings you made to take effect.

I want to make a reservation right away that these tips do not always help and not for everyone. You may need to experiment with different channels. However, very often this method helps to increase the stability and speed of your connection, so it's definitely worth a try.

If you have already opened the router settings anyway, then do not forget to check its security, as described in!

today they are not just popular: they are a must-have in every home and office. After all, users with them acquire not only a stable connection to the World Wide Web. The main thing is that this connection should also be of high quality, and ideally - super-fast!

But what if the provider provides a speed of 100 megabits per second, and on Wi-Fi it barely reaches the mark of 20-30 Mbit per second? It's time to start using these far from superfluous megabits, and for this you need to figure out how to quickly and accurately increase the speed of WiFi on modern and not very models of routers.

Improving the speed of the Internet through the Wi-Fi network of the router

For the simplest Internet surfing, scrolling through social networks, online stores and similar web portals, downloading a track or a picture, even a device bandwidth of 3-5 megabits is enough. In this case, there will be no difficulties with WiFi speed and its increase, because. the user does not feel any inconvenience. Pictures download, Facebook and Twitter open, what else do you need?

Problems become apparent when the user watches, for example, a video in good quality and sees that the speed of information transfer via Wi-Fi only reaches the minimum 20-30 Mbit per second, while the tariff is designed for 100 Mbit or even more. How to increase the speed of wireless Internet through a Wi-Fi router in this case?

To get started, there are 3 points to be aware of:

Determine the capabilities of the device itself. Budget devices with a basic configuration give out an average Internet speed. In inexpensive units, the manufacturer can save on the chipset (1 core, minimum frequency), the amount of RAM, and the power of the antennas. For home use and simple online work, this is quite enough. If you need to quickly download large files, play walkers and shooters, you should think about purchasing a more expensive device (for example,).
Look at the Wireless N label on the box. The numbers next to this inscription, for example 300, mean the maximum achievable Wi-Fi speed (if you use the latest 802.11N standard). If an older standard is used, then the indicators will be somewhere between 1.5-2 times less than the specified number.
Update firmware. Before trying to increase wifi speed using manipulations with the settings, you need to update the firmware of the device to the newest one (it is also advisable to do this for). In addition, the compatibility of computer software can have a negative impact on speed. Therefore, it is worth visiting the web portal of the developer company, downloading the most new version, go to Windows Device Manager or adapter settings, make changes to the firmware.

What else needs to be checked before setting up the unit? The number of gadgets connected to it. After all, the device has to “share” the initial connection speed for all. To successfully solve this, you can use specialized ones that will help you set up a wireless virtual network without "jumps" in the pace of work.

Another simple method to increase the speed of Wi-Fi operation several times is to use an interval of 5 gigahertz. Some routers support 2 bands: 2.4 and 5 GHz. Most often, Wi-Fi networks are operated on the first of these frequencies. And it turns out that the more devices work at 2.4 gigahertz, the worse the connection can be. Residents apartment buildings this should be known firsthand.

5 GHz is used less often, as a result, it has less interference and better connection quality. Nuance - in order to operate the specified frequency, a mobile or stationary device must support it ( good example – ).

After everything is checked, you can start digging into the settings.

Translate all gadgets to 802.11N

When working with the "ancient" standards 802.11G or 802.11B, the ability of the network to quickly transmit information is reduced to 80%, so it's time to switch to a more up-to-date one.

Starting the standard is very simple:

in the Internet browser, you need to write the ip-address of the gadget (indicated on the label);
enter login and password (factory or personal);
go to the menu and select "Basic settings";
go to "Wireless Mode" and select 802.11 N from the list.

Nuance: in devices from different manufacturers (for example, or ) the settings may differ. More details can be found in the instructions for use that comes with the unit.

You should not use the outdated WEP or WPA / TKIP: they can significantly “slow down” the speed of the wireless Internet. Even if you switch to 802.11N, but do not change this parameter, you will not be able to increase the speed on any router model. In addition, this standard provides a high degree of security by working in tandem with a block cipher called AES.

To change these settings, you will need:

go to the device settings (how to do this is described above);
select "Advanced settings";
go to the security section;
set: network authentication - WPA2-PSK, encryption - AES.

Click on the "Change" button at the bottom of the screen. The settings will take effect after the device is rebooted.

After 802.11N is connected, in order for the Internet to reach record heights in speed, you need to activate WMM. This parameter goes in tandem with QoS (quality of service) and is well suited, for example, for streaming video.

WMM is connected in the Wi-Fi settings. For this you need:

go to "Wireless Mode";
click on "Advanced settings";
click on On opposite the inscription WNN.

WNN is also required to support the PC's wireless adapter. You can connect through: Settings - Properties - Advanced.

Setting the channel width to 20 MHz

802.11N technology for higher network bandwidth works with broadband channels by default. But it should be borne in mind that this will be effective only with an excellent signal. Under standard Wi-Fi network conditions, this is almost impossible to obtain. In addition, 40 MHz channels operating at 2.4 GHz can interfere with other gadgets that use this band.

And with a weak signal, a broadband channel has the opposite effect - the data transfer rate decreases, interference appears. In devices like the use of such channels is the default, so you should change it manually.

In the advanced Wi-Fi settings, you need to set the value to 20MHz opposite the "channel width" item. Then click on "Save" and reboot the device so that the updated parameters take effect.

During manual setting wireless network, you need to choose the value not to the maximum, but the optimal number. This can be done in the interface of the aggregate (for example, ):

setting up a wireless network;
signal strength;
gradually lower the value.

You need to stop when at the farthest point of the room / apartment / office, the laptop or smartphone stops “seeing” the network. After that, you need to increase the transmitter power by one division and you can use Wi-Fi at optimal settings.

The maximum power value will automatically be set, but if the device is located directly next to a PC or laptop, this may lead to loss or a weak signal. Yes, and an extra temptation for neighbors ... And if the router settings do not provide for the replacement of this value, it is worth increasing the distance between it and gadgets that receive Internet from it.

To summarize: to increase the Wi-Fi speed on the router, you need to set:

Options	Meaning
frequency range	2.4 or 5 GHz
wireless standard	802.11N
network authentication	WPA2-PSK
encryption	AES
MultiMedia (WMM)	on
channel width	20MHz

After all the steps, it is important not to forget to restart the unit. The procedures described above will significantly speed up the pace of the Internet through Wi-Fi and will allow you to productively use the capabilities of both budget and more expensive devices.

AT modern world it is already difficult to find an institution that does not have wireless access to the network. Even public transport has Wi-Fi. What to say about houses and apartments. The time has passed when home Internet chained you and the computer to a certain place. Now the network catches throughout the apartment, you can access the Internet from any device.

These are, of course, pluses, but there are also minuses. Often the demon wired Internet does not correspond to the speed declared by the provider. For example, when connecting the tariff, you chose the speed of 100 Mbps, then when connecting via Wifi, the speed will be lower. This speed will be when connected directly via cable. Through wifi - about 50-60 Mbps.

Why is the Wifi internet speed slow?

Wireless Internet is convenient. Wired Internet- it's fast and reliable. It is very difficult to argue with this. After all, wired Internet is connected directly to the computer. It works faster and more stable.

When connecting to a router wirelessly, be prepared for less powerful Wi-Fi. It won't be as fast or reliable. In this case, the equipment itself chooses which signal to pass. The router is designed to distribute the stream to other devices. This is the main reason for the low speed of the Internet over a wireless network.

The router cuts the speed several times. This indicator will depend on the power of the device. But, it is worth noting that the more powerful the equipment the more expensive it is. In this case, expensive equipment justifies expectations. No wonder there are different routers on the market. There are cheap ones, there are expensive ones. There is a difference between them, otherwise there would be no point in creating them, and the client would not need to buy them.

We found out why the router can cut speed. The main reason is its power, which depends on the price.

How to increase the speed of the Internet through a wi-fi router

You can increase the connection speed of the router through its interface. It is worth noting that routers come from different companies: Rostelecom, Beeline, etc. Accordingly, the bandwidth for transmitting and receiving Wi-Fi data will be different.

The access point to the interface will also be different. As a rule, it is written in the instructions or on the router itself. There you can find username and password to enter the office. So, what are the ways to increase the speed of wireless Internet:

A few more options to increase speed

To increase the speed of the router, you must:

If you have done all the necessary manipulations with the router, but the Internet speed does not rise, then you need to look at the settings on the computer.

How to increase internet speed on laptop

If checking the router itself and change settings it did not give results, then you need to go to the laptop:

To do this, you need to go to the task manager. You can use the combination Ctrl-Alt-Del.
Select the "Performance" tab. If you see that the network is overloaded, but you are not using the Internet at that moment, you need to go to the processes that are running in the background and disable them.

If this test fails, then need to see autoload. Remove unnecessary programs. For this you need:

Use the combination Win + R.
In the window that opens, enter "msconfig".
Select the program you want to remove from startup.

If these actions did not lead to a positive result, you need to check the system for viruses. If the program finds viruses, then after removing them, everything will be in order.

If the antivirus did not help, that is, did not find any problems, then you can update the drivers to latest version. Required driver can be found on the official website of the company that manufactures computers of your brand.

Another reason why the Internet speed is slow is the wrong routing configuration. To fix this, you need reset old settings. For this you need:

Run cmd mode as admin. The mode is started by right-clicking on "Start".
Now you need to select the desired option.
After that, a console mode prompt will appear.
On the command line, you need to write "route-f". After this action, the connection will disappear for a few minutes.
Now you need to enter "ipconfig / renew". Press Enter.

If these steps did not help, then you need to reinstall the system. This method is radical and serious. If you never did these it is better to entrust it to a professional. This option will help to achieve the desired effect. If that's the point.

So, we talked about wireless Internet connection. We analyzed options for increasing the speed of the Internet through wi-fi and a laptop. It should be noted, before using tips, check the speed of the Internet, what signal the router has. If the router transmits a signal of 50–60 Mbps, then this is normal. Also consider where the equipment and gadget are located. Before resetting your laptop, use all the options to improve the speed of the Internet via wi-fi.

Internet speed over wifi is another question that you will probably have if you carefully read the previous articles on my blog and have already done it at home. wireless Internet. Surely many have already noticed that you have low wifi speed connections - often much lower than they were when connected via cable and than indicated in the tariff plan. Also, for sure, at least half of those reading this article have come across such a mystery that support for 100 or even 300 Mbps is indicated on the box of a router, access point or adapter, and real speed Internet over WiFi and local network is much lower. Let's find out why router cuts internet speed and how to increase it!

The speed of a wifi connection, like the Internet in general, is measured in kilobits or megabits per second. They are denoted by the following abbreviations: Kbps, Kb / s, Kb / s, Kbps, Mbps, Mb / s, Mb / s, Mbps. Do not confuse them with other speed measurements - kilobytes and megabytes per second - this is not the speed of the Internet, but the data transfer rate of the program. It is most often displayed in utilities such as ftp or torrent clients. They are denoted very similarly, but the letter "B" ("B") is large here: KByte / s, KB / s, KB / s, KBp, MB / s, MB / s, MB / s or MBps. Their ratio is as follows:

1 byte = 8 bits

Accordingly, if the ftp client displays a data transfer rate of 5 megabytes per second, then multiply this number by 8 and get an Internet speed of 40 megabits per second.

Now let's define what we mean by the concept of "router speed". There are actually two characteristics:

The speed of working with the Internet, that is, from the WAN port to the LAN port.
The speed of operation between two devices within the same local network, that is, WLAN-WLAN

How to measure the speed of a wifi router when working with the Internet?

To measure the speed of the Internet via wifi, it is not necessary to run programs and perform mathematical operations. Exist online services to help you do it automatically. We will use the most popular site SpeedTest.net.

Click on the “Begin Test” button and wait for the system to test. Here is the result:

It turns out that I have an incoming speed of 33.56 Mbps, and an incoming speed of 49.49 Mbps. It was the speed of the wifi connection to the Internet that was measured, and not the speed of the wifi router's cable connection. Now we disconnect from wifi, connect the PC to the router via cable and make the same measurements. If it turned out that the cable speed is higher than the speed of the wifi connection, then we read the article further.

Scientific experiment - measure the speed of a wifi connection

Theory-theory, but let's evaluate in practice how much the speed readings differ in the reception-return given at various types connections.

As we can see, the highest speed is obtained when the cable is connected directly to the computer - 41 Mbps per reception.
A little less - when the Internet goes by cable, but through the mediation of a router - 33 Mbps per reception
And even less - via wifi: 26 Mbps

From this we can conclude that the router cuts the speed for objective reasons, which we will now understand.

Router cuts wifi speed

So, if you have a low wifi speed, then the router cuts the speed. Scientifically, this is called throughput or WAN-LAN routing speed. The filling of the device is responsible for this parameter, the parameters of which are usually indicated on the sticker on the bottom and are designated as H.W. — Hardware. If they do not match your tariff plan, then you need to change the device to a more powerful one with more bandwidth.

Also, the speed of the Internet via wifi depends on the type of connection to the provider. In decreasing order, they look like this: DHCP and Static IP - VPN - PPTP.

It turns out that if the Wi-Fi data transfer rate is up to 300 Mbps on the box of the device, and the WAN-LAN parameter for this model in combination with the type and protocol of connection to the provider is 24 Mbps, then the Internet connection speed cannot exceed 24, but in real life it will most likely be less.

But the reason may be not only in the router - the hardware and software of the wifi adapter on the computer receiving the signal must also have the appropriate parameters.

You also need to take into account that indicated in the instructions and on the stickers specifications are designed for ideal working conditions - with a minimum distance from the router to the device, in the absence of third-party interference, signal-absorbing materials and with minimal network load. That is, if you have a naval communication point near your house, the router is in the next room behind a reinforced concrete wall, and at the same time your sister downloads all the series of "Interns" by torrent, then it is quite logical to assume that your speed wifi internet will be much lower than indicated on the box and in the tariff plan, and you will enjoy the game in Counter strike will not work. In practice, the real speed of a wifi connection is two to three times less than indicated in the specification.

WiFi speed through router

In "nature" there are several standards for wireless data transmission technology over wifi. I will give below a table in which theoretical and practical speeds are correlated:

Standard	Speed in theory in Mbps	Speed in practice in Mbps
IEEE 802.11a	Up to 54	up to 24
IEEE 802.11g	Up to 54	up to 24
IEEE 802.11n	Up to 150*	Up to 50
IEEE 802.11n	Up to 300**	Up to 100

* - for devices operating at a frequency of 40 MHz in 1 stream
** - for devices operating at a frequency of 40 MHz in 2 streams

Speed when operating within the local network (WLAN-WLAN)

Many users may also note the fact that the router cuts the speed not only when accessing the Internet, but only when exchanging data within the local network.

The whole joke is that when several devices are actually working at the same time, in fact, the router works with each of them in turn. It turns out a kind of queue, which is why the speed is cut - it becomes many times less than when the router works with only one client. And when exchanging data between two devices, for example, when you transfer files from one computer to another via LAN, it will be 2-3 times less than the total real speed over the network.

Let's take an example - we transfer data between 2 computers - one with an 802.11g adapter (up to 54 Mbps), the other - 802.11n (up to 300 Mbps). The router also has 802.11n (up to 300 Mbps)

Regardless of what fancy router you have, in theory, the maximum speed within the network, even in theory, will not exceed 54 Mbps - according to the maximum data of the slowest adapter. In practice, based on our table, this will be no more than 24 Mbps. As we found out, when working with several clients at the same time, the router will interact with them one by one, that is, the actual speed will be 12 Mbps. When moving away from the access point at a certain distance, it will fall even more.

At the same time, on the computer that has an “N” standard adapter, as a mockery, the speed measurement utilities can show theoretical data of 150 Mbps, which is really the maximum possible for our router.

Many PC users, when determining the speed, are guided by the indicators displayed in the connection information

This is fundamentally not true, since here in the "Speed" column the theoretical supported by the adapter is displayed. For real measurements, we will use the AIDA32 program, which has a benchmark for testing the speed between two devices on the network.

We get the following:

by cables - 11217 Kilobytes per second.
cable + WiFi - 9166 KB / s
pure WiFi - 4303 KB / s

Here, the units of measurement are slightly different - in the first part they were calculated in megabits per second, and in the second in kilobytes per second. To convert data from the second part to Mbit / s, we will use the online converter. We get 10.9, 8.9 and 4.2 respectively.

As you can see, with the connection of one, and even more so two adapters, the speed is significantly reduced, and the amplitude between the highest and lowest speeds in the test also increases, that is, the stability of data transfer drops.

Which of you, the most observant, was probably able to make one observation - despite the fact that in several measurements we used devices whose maximum speed should be up to 300 Mbps, in all tests the speed never exceeded 100 mb / s.

This is due to the fact that the actual speed of Internet connections depends on the technical characteristics:

Provider equipment
Cable stretched to your computer or router
WAN port of the router
WiFi adapter or computer network card
Internet tariff plan

It turns out that in order to achieve maximum performance of the entire system, it is necessary that each of its components maintain the declared speed. In the event that you connect to a tariff with a maximum speed of more than 100 Mbps, then both the network card or wireless adapter, and the router, and the cables with which you connect your PC to the router must support this speed, otherwise it will rest against the ceiling, indicated by the slowest link.

For example, if a PC network card and a router support a speed of 1 Gb / s, and the connection goes through a simple patch cord, which is on the shelf of any store, then up to a speed of 1000 Mbps. you will be very, very far away.

In most cases, we use cables of the Fast Ethernet standard (category 5), the speed of which is limited to 100 Mbps - when connected to a tariff from a provider that supports operation at this speed. This is the cable I have - that's why a quality 150 Mbps adapter performed just as well as a more advanced 300.

That is, the maximum task for any wireless equipment is to get closer to the reference speed, which is provided by a cable connection. Which, in turn, is limited by the capabilities of the tariff and WAN ports of the router and computer.

In fact, buying equipment with a speed higher than 150 makes sense if your provider provides you with tariff plans for gigabit Internet (category 5e and 6 cables). But do you know how much it costs? Let's look at the tariff scale of my provider:

For a theoretical speed above 100 - 1200 rubles per month - not sickly so, is not it? Are you ready to give this amount? Me not.

So in practical realities, the question of choosing a router and adapter is to ensure that the equipment meets the manufacturer's specifications as much as possible and brings us closer to the maximum speed for which it is designed tariff plan your internet provider.

In this case, you should pay attention not only to the bright enticing speed characteristics indicated on the equipment packaging, but also to the specifications written in small print in the instructions. For example, at the declared high speed, very often the instructions indicate that WAN port The router only supports speeds up to 100 Mbps. And this means that no matter how steep the tariff we pay, we cannot achieve anything above this value.

To the credit of the devices we reviewed today, they perfectly showed their quality and, in conditions close to ideal, were in no way inferior in their work to connecting to the Internet via cables in accordance with their declared parameters.

Other factors affecting the low speed of WiFi through a router

As you know, wi-fi is a technology for transmitting data over radio channels. Therefore, the operation of other devices may have a strong influence and cause interference.

First of all, household appliances, as well as other wi-fi networks that are around you and operate in the same frequency range. Now in nature there are two ranges - 2.4 and 5 GHz (gigahertz). 802.11b/g wireless networks operate in the 2.4 GHz band, 802.11a networks operate in the 5 GHz band, and 802.11n networks can operate in both.

5GHz (GHz) is a relatively new standard, so if you use it, there is a better chance that it will not be loaded by other devices.

You need to plan the speed of your future WiFi network even before buying devices that will work in it!

If you purchase a router that supports 5GHz and the latest standard with data transfer up to 300 Mb / s, but at the same time an adapter is installed on the computer that supports only 2.4 GHz and speeds up to 54 Mb / s, then this bundle will work exactly at the maximum adapter specifications. As they say, the speed of the squadron is equal to the speed of the slowest ship. Plus, keep in mind that these values are maximum under ideal conditions - in reality everything will be slower.

Finally, a few more sources of interference are Bluetooth, microwave ovens and baby monitors. They also operate at a frequency of 2.4 GHz, so it is not recommended to use a blue-toothed headset, heat soup and connect to wifi at the same time.

conclusion - how to increase the speed of wifi?

If you look closely at the technical characteristics of the router, you will notice that for many models, the speed of the LAN port also does not exceed 100 Mbps, so even if they have 300 Mbps via WiFi, when one of the devices is connected via cable, the speed will not exceed 100 .

If we talk about a purely wireless connection, then here, in addition to the declared parameters of devices for the supported wifi speed, such a concept as the “duplex” mode of the router comes into play. That is, speaking in Russian, it processes a request via WiFi from each of the clients in turn, which is why a kind of queue of requests is formed, and the speed drops at least 2-3 times in relation to what it could be during operation with only 1 computer. And this is under ideal conditions - in the case of interference, distance from the access point and the influence of others external factors it will be even lower.

From all of the above, we can conclude: no matter how hard we try, in ideal reception conditions and with a router and adapter that support the same communication standards, in most cases we will not be able to achieve speeds of more than 100 Mbps - which our tests clearly showed . It makes sense to buy high-speed equipment only in a complex (router + cable + adapter + network card) for ALL devices on the network and when connected to a gigabit tariff.

In order to increase the speed of a wifi connection, you need:

Select a provider with a DHCP connection ()
Use a router and adapter with the highest bandwidth that supports IEEE 802.11 N or AC ()
Use a router and adapter from the same company
in such a place in the apartment that it is not covered by thick ceilings and is located far from sources of radio emission, but as close as possible to the location of your devices. If the signal source was initially set incorrectly, then an article about will help you.
Keep in mind that with a heavy load on the home network, the time it takes to open pages in the browser will increase. To improve performance, you can expand the channel from 20 to 40 MHz.

Following these rules, you will always have high-speed wifi internet in your house. I wish you good luck, and for a snack, an interesting video on increasing wifi speed and radius with a can of beer!

1. Download and install the program. It will help us identify free channels in your environment. The program is free and works on all versions of Windows.

2. Run inSSlDer. After a short scan, you will see something like this:

3. Open the router settings in the browser and change the channel. Usually this is enough to enter into the address bar 192.168.1.1 .

5. Reboot the router and reconnect your computer to the network for the settings you made to take effect.

If you have already opened the router settings anyway, then do not forget to check its security, as described in!
