Bandwidth wi-fi router. How to increase the speed of Wi-Fi on a laptop.

Progress in the field of digital communication is gradually replacing the usual wired connections between devices, replacing them with wireless counterparts. For example, now it is almost impossible to purchase a new router that would not have built-in support for the Wi-Fi standard. To use this type of communication or turn off the radio module is up to the owner, but in any case it is necessary to pay the full cost of the device. Very often, users of wireless connections are concerned about the question: “How to increase the speed of WiFi?” Indeed, sometimes from a computer that has connection to the provider’s equipment via cable, it is much more comfortable to work with global network resources, since there are no noticeable packet transfer delays, which is not the case with Wi -Fi. This is despite the fact that the 50 Mbit channel has long become a standard. Probably, until a new working principle is developed, users will be wondering how to increase the speed of the Internet transmission. However, it is necessary to live and use now. Therefore, we will consider WiFi. The given recommendations allow to improve the speed characteristics of the equipment for each user, even if he does not have special knowledge in this topic.

Old equipment

Frequently, a user has an old wireless routerwhich is not used, gathering dust on a shelf in the closet. In this case, you can use it as the main signal. Sometimes the expansion of the coverage area allows to increase wi-Fi speed, since ping (data transmission delay) depends on the signal intensity. For example, the situation when a smartphone “sees” a wireless network is familiar to many, but it works with it with tremendous delays, as if by a successfully forgotten Dial-Up. This is because the device may be on the border of the coverage area. Thus, if you need to figure out WiFi, you should remember if there is extra equipment in the inventory.

Accommodation

Sometimes, the location of the wireless router is left without proper attention, suggesting that radio waves penetrate any obstacles. This is partly true, but few people know that, because of the low power of the transmitter, sometimes even a closed wooden door reduces speed several times. So, in Russia the power of household Wi-Fi devices limited to 100 mW, so as not to cause noticeable harm to human health. The conclusion is simple: the equipment should be installed as high as possible, where nothing prevents the propagation of waves, and you should not forget that the antenna should be oriented vertically. Sometimes this is already enough to stop looking for the answer to the question: "How to increase the speed of WiFi?".

Neighborhood

There are many home appliances that generate radio waves or high-frequency interference in the air during their work. Thus, a mobile phone or a microwave located next to the router can distort the signal, thereby causing a slowdown in transmission. The rule is simple: Wi-Fi equipment should be placed as far as possible from household electrical appliances.

Access limitation

If you do not make changes to any device in the coverage area and working with the appropriate standard, it is possible to go to the global network. And it is absolutely not important who its owner is. Although for unlimited tariffs   You should not worry about traffic, the speed is divided between everyone, which is not very good. The solution is simple - enable WPA password.

These simple steps can improve the speed of the channel without the need to purchase new equipment.

Greetings to all blog visitors!

Many users, after setting up a Wi-Fi network for them, ask the same question: “why the speed on the router is 150 Mbit / s (300 Mbit / s), and the download speed of files is significantly below 2-3 MB / from...". This is actually the case and it is not a mistake! In this article we will try to figure out why this is happening, and whether there are ways to increase the speed in the home Wi-Fi network.

1. Why is the speed lower than indicated on the box with the router?

It's all about advertising, advertising is the engine of sales! Indeed, the larger the number on the package (yes, plus a bright original picture with the inscription "Super") - the more likely the purchase will be made ...

In fact, the package is the maximum possible theoretical speed. In real conditions, the throughput can vary greatly from the numbers on the package, depending on many factors: the presence of obstacles, walls; interference from other devices; distance between devices, etc.

The table below shows the figures from the practice. For example, a router with a speed of 150 Mbps on a package - in real conditions will ensure the speed of information exchange between devices not more than 5 MB / s.

2. Dependence of Wi-Fi speed on the client’s distance from the router

I think many who set up a Wi-Fi network noticed that the further the router is from the client, the lower the signal and less speed. If to show on the diagram the approximate data from practice, then the following picture will turn out (see the screenshot below).

Chart of dependence of speed in a Wi-Fi network (IEEE 802.11g) on ​​the distance between the client and the router (approximate data *).

A simple example: if the router is 2-3 meters away from the laptop (IEEE 802.11g connection), then the maximum speed will be within 24 Mbit / s (see the table above). If you move the laptop to another room (for a couple of walls) - the speed may decrease several times (as if the laptop were not 10, but 50 meters from the router)!

3. Speed ​​in wi-fi network with multiple clients

It would seem that if the speed of the router is, for example, 54 Mbit / s, then it should work with all devices at that speed. Yes, if one laptop is connected to the router in "good visibility" - then the maximum speed will be within 24 Mbit / s (see the table above).

When connecting the same 2 devices   (say 2 laptops) - the speed of the network, when transferring information from one laptop to another will be only 12 Mbit / s. Why?

The thing is that in one unit of time the router works with one adapter (client, for example, a laptop). Those. All devices receive a radio signal that the router is currently transmitting data from this device, to the next unit the router switches to another device, etc. Those. When the 2nd device is connected to the Wi-Fi network, the router has to switch twice as often - the speed, respectively, also drops twice.

Conclusions: how to increase the speed of a Wi-Fi network?

1) When buying, choose a router with a maximum data transfer rate. It is desirable to have an external antenna (and not built into the device). For more information about the characteristics of the router - see this article:.

2) The fewer devices will be connected to the Wi-Fi network - the higher the speed will be! Just do not forget that if you connect to a network with, for example, an IEEE 802.11g standard phone, then all other clients (say, a laptop that supports IEEE 802.11n) will follow the IEEE 802.11g standard when copying information from it. Those. Wi-Fi speed will drop significantly!

3) Most networks today are protected by WPA2-PSK encryption. If you disable encryption at all, then some router models will be able to work much faster (up to 30%, tested on personal experience). True, the Wi-Fi network in this case will not be protected!

Everyone who gets on this page wonders how to increase the speed of the Internet via Wi-Fi. Users who use the Internet to download large amounts of data (games, movies in FullHD) through torrent networks face a problem when, with a bandwidth of 20-100 Mbit, Internet speed through Wi-Fi does not even reach half of the tariff plan.

Let's sort through the possible options for increasing the speed of the Internet via Wi-Fi.

1. Choose the right equipment.

Many of the users do not understand the technical details of the routers and buy one of the cheapest devices in the store, order them online or take what the seller advises. When purchasing a budget device, one should not expect high speed from it, especially in a remote room.

2. Updating the firmware of the router for Wi-Fi

Periodically, you should update the firmware of your router to latest version   through the setup menu. Such an action in most cases can be a way out of most situations, including helping to increase the speed of Wi-Fi Internet. You should also update the driver by downloading them from the official website of the manufacturer of the router.

3. Choose the right place for the router

The router should be placed in such places so that the distance from it to all points of use of the signal is approximately the same. The signal is largely muffled, passing through the walls and metal partitions, because of which the speed of the Internet through Wi-Fi decreases. The antenna should be directed vertically upwards; it is better not to install devices with intense electromagnetic radiation that interferes along the signal path.

4. Use the 802.11n standard

Increase a speed Wi-Fi router   allow use of standard wireless connectivity   802.11n. It provides data transfer speeds of almost four times as much as its predecessor 802.11g, which theoretically supports speeds of up to 54 Mbps. The operation of the router, released until 2009, will not allow to exceed this figure, which in practice will result in a 25-30 Mbit maximum. Follow the advice is only in the case when all subscribers of the network support the new standard.

5. Set up private network security.

To prevent the theft of the Internet and, as a result, reduce its speed, always use home encryption wireless network. It is recommended to choose a modern Wi-Fi WPA2-PSK encryption algorithm through the settings of the router. Outdated methods are much easier to crack and reduce the bandwidth.
  If this option is unacceptable, you can use an unencrypted connection with filtering by MAC-addresses, adding the necessary devices to the list of trusted ones. Thus, the router will not be loaded with encryption of the transmitted data, and the connection will still remain secure.

6. Choose the correct broadcasting frequency.

The signal of a wireless connection is affected by a huge amount of electromagnetic waves that surround the whole surrounding space. To minimize the influence of third-party radiation on the signal of the router, you should select the frequency at which the number of neighboring devices broadcasts the minimum. In the manual settings, we indicate the freest of 14 channels, which will slightly increase the speed of the wireless Internet.

7. Go to the frequency of the broadcast router in 5 GHz

How to increase speed internet wifi   router playing with the settings of its operating frequency? The fact is that many household appliances and neighbors wi-Fi hotspotscausing interference. Using the frequency of 5 GHz to provide wireless Internet will allow you to avoid a large amount of interference, but not every router supports this frequency of operation.

See detailed instructions:

You have been using the Internet for a long time, or have just connected it, you probably should already be familiar with what a Wi-Fi and router are. Thanks to this device you get wireless Internet   in the whole area of ​​an apartment, office or even you can use this blessing of civilization in certain public places. If the signal is bad, then the speed is small, and when the speed is not enough, then sometimes you may take a very long time to load or not open some pages at all. In a public place, you cannot do anything about it, except how to get closer to the source, but if a router is in your home, this is a completely different question. Today we look at how to increase the speed of Wi-Fi.

In fact, the reasons may be more than enough. Now we will try to list in more detail what determines the speed of Wi-Fi and what can “eat” this speed on your device:

How to solve a problem

We will conduct a phased diagnosis of the system and the router, simultaneously checking all possible reasons and explaining how to fix them or what to do.

Anyway, the first thing we need to do is start at a distance. It is worth mentioning that the transmitter should be placed somewhere in the center of the apartment - then Wi-Fi will stop cutting speed. Although if you only have a device for one antenna, then you have to sacrifice something: either to rearrange the router, or change it to another, otherwise the signal is unlikely to pass through the whole house. It is also necessary to take into account the thickness of the walls.

If you have a powerful router, you have moved it closer and you have a good tariff planthen it's time to check the integrity of the antennas. The easiest way to check the router, and the computer is better to leave the professionals.

Another interesting variant of the problem is that routers usually work on the same frequency and in a high-rise building they block each other’s signals.

In order to switch your router to a different frequency, search the Internet for instructions on how to go to the settings of your equipment, since each manufacturer has specified this individually.

If everything is in order, then it is necessary to turn off the router and disconnect all the wires, and then connect everything in a new way and check again: if the picture is the same, then proceed to the computer.

Laptop / PC problems

Now we need to check what is taking away your speed, and figure out how to increase the speed of Wi-Fi on a laptop. Press the key combination ++ - the task manager will be displayed in front of you. We look at the tab with performance - if you see that you are not using the Internet right now, but the network is loaded, you can go to background processes and look there.

If after that Wi-Fi on a laptop is slow, then the last thing to advise is to update the driver. And in the usual way - through the system - as a rule, it will not work, so it is best to use proven driver packs like, for example.

One of the causes of problems with speed can be considered wrong settings   routing. Their dumping is done fairly quickly and does not harm the general state. operating system. To do this, go to the “Start” menu and find the “Command Line” in it, then click on its icon and select “Run as administrator” - a small “Run” window will open.

Now we enter there cmd and click “Ok” - another small window will appear with a black background, which is called command line. All that is left for you is to enter the route –f and press, after which the Internet will disappear.

After that, without closing the lines, enter ipconfig / renew without a space and again click on. If this option did not work either, then the netsh winsock reset catalog command would be an alternative.

An extreme case is to reinstall the system, which, if you do not possess certain skills, it is better not to do. Usually, after this, everything can return to normal, but only if there is no damage inside the notebook itself.

A little advice: for your Wi-Fi to give maximum speed, it will be best if, if possible, you still get a more powerful antenna for it; Of course, on the Internet you will find an abundance of various ways with reflectors and home-made antennas, but they either will not give effect, or can lead to equipment breakdown.

How to measure the speed of Wi-Fi connection: Video

Poor internet speed through a router is one of the most “popular” problems of all lovers. wireless connection. In previous articles we told, and also - we recommend that you familiarize yourself with this material.

Here we will tell a few more “professional secrets” how to increase the speed of the Internet through a router, and why the router does not provide full speed even with the optimal location of the router.

Does the speed of the Internet depend on the router?

Data transfer rate in wireless wifi network   (Wireless Fidelity [Wi-Fi]) depends on the selected standard. Also, this indicator should take into account the presence of interference appearing in the same range, and the conditions of placement of the access point.

N standard speed

To achieve maximum speed parameters, you need to use the IEEE 802.11 group standard N standard. This group has created several standards.

• - 802.11A
• - 802.11B
• - 802.11G
• - 802.11N
• - 802.11R

The b-standard is the lowest of the speeds, therefore, to increase it, one should switch to the g-standard. However, the maximum speed of the g-standard is significantly lower than that of the n-standard. Therefore, in order to achieve the maximum speed of Internet distribution over the wireless network, you will need to install an n-standard in the router. This figure is in the range of 150 MB / s, if the transfer is conducted on a single antenna. Theoretically, the speed of Wi-Fi router can be increased to 600 MB / s from four antennas.

Closer to reality

But not everything is so simple. Real internet speed through wifi router   differs from the declared by developers twice - downwards. Moreover, various other factors affect transmission.

• Interference factor. Very few customers can support the 5 GHz range. Most of them work in the overloaded 2.4 GHz band, whose channels also use microwaves, cordless telephones and neighboring access points.
•   We usually divide between clients, which also greatly affects its throughput (respectively, the Internet speed through the router drops).

Thus, essentially through a wifi router is quite difficult. Moreover, if the router does not work in pure N-mode, but in compatibility mode with previous standards, then it must be understood that a device that supports the standard of the previous generation will not be able to work at IEEE 802.11n speeds. The speed of data transmission via wi-fi router in this case will correspond to the supported standard.

Maximum results can be achieved only on a “clean” n-standard with a configuration of several receiving and transmitting antennas - 4x4, for example.

The router reduces the speed of the Internet: how to fix

Set the bandwidth on the n-standard

Wireless routers typically support various data transmission standards, including N and mixed modes based on this standard. Take for example the Netis Wi-fi router or TP-Link. In the special utility (settings) of these routers, you can find the section "Wireless Mode". This tab contains the basic settings of the wireless network created by the access point.

Provides the "Radio Frequency Range" option. It is in this drop-down list you can find the desired setting 802.11n.

The same setting is available for the TP-LInk router.

As you can see, it is common to many routing devices.

Selecting this option will allow the device to transfer to a higher level of data transfer speed and significantly increase the speed of the Internet via wifi. However, it will have to connect to it gadgets that work with the N-standard.

How to increase internet speed via wifi router: channel selection

Your neighbor also uses a wireless router, but it uses an n-standard b-mode compatible. The channel of the neighboring router is the 1st, and your 3rd - then the throughput channel of your router will experience interference from the neighbor, as their channels will intersect. Accordingly, you will get a weaker Internet speed through the router. To solve this problem, you will have to choose another data transfer channel.

The channel is configured in the tab wi-fi setup   wireless mode router netis.

Here is a drop-down list of channels. It is better, of course, to leave the channel choice on the conscience of the device itself, by setting the Auto option. If necessary, you can choose the desired channel.

Why is the speed through the router less than the cable?

Wi-fi Multimedia

The WMM parameter is closely related to the QoS (Quality of Service) parameter, which is used to ensure better quality   data transfer when working with VoIP-applications, streaming video. Network packets of such applications are prioritized for processing due to the need to ensure a more stable operation of multimedia applications — they should work with a smaller number of errors.

Netis or TP-Link routers also have this feature. It must be enabled and located in the Wi-fi settings.

In these routers, it is displayed as a separate radio button. Checking its box enables the WMM option. Also, it should support wireless adapter   computer.

Channel width reduction

In some cases, the rate of transmission of packets over the network can be increased by reducing the channel width. To increase the network bandwidth, the developers of the IEEE 802.11n standard decided to expand the channel from 20 MHz to 40 MHz. However, the use of broadband channels is not always justified in the habitat of citizens. Extended range often leads to the opposite - wifi internet speed is cut.

And routers with wireless mode   By default, they are configured to use exactly broadband channels.
