The modern Internet provides a wealth of advice on how to strengthen the signal of a Wi-Fi network. But the disadvantage of many articles is that useful information is hidden behind mountains of recommendations that are not related to the given problem or have a meaning that is completely indirect. As a result, the user tries to increase the range of the Wi-Fi signal using settings that cannot be used to solve such problems. They are simply useless for the network, and even more so for the radius of its activity.

Updated and larger instructions: .

The task of strengthening the signal of a Wi-Fi network involves influencing changes in the radius of its coverage and the operating distance of Wi-Fi. You can often encounter a problem when it is impossible to use Wi-Fi in the back rooms of your home, although the router has been restored and no problems with its operation have been identified. Inconvenience may also arise if wireless data transmission is available on different floors of the same room.

Factors affecting the distribution area of ​​a Wi-Fi signal

What determines the range of a Wi-Fi network? There are many answers to this seemingly simple question. The following factors play an important role in the distribution area of ​​the Wi-Fi network:

• Number and power of router antennas;
• Thickness of the walls in the room;
• Number of wireless data transmission systems located nearby;
• The location of the peripheral device that provides Internet access;
• Other interference.

Often, when purchasing a router, buyers ask to choose a device that will provide a stable signal for a home with a different number of rooms or a private house. But it is impossible to advise anything specific in such cases, since many conditions need to be studied. The area of ​​the room may be the only factor that you should pay attention to when buying a router. For an apartment with one room, the option of inexpensive equipment with one antenna with a power of 3 dBi would be quite suitable. To provide a Wi-Fi network signal to rooms with a fairly large area, you need to take into account other characteristics of the router. At the same time, the price factor should not be taken as the basis for purchasing the necessary equipment. For comparison, the device has a number of advantages: multiple antennas, a function to increase the radius of Wi-Fi activity from Asus. But if you use it along with another model, less expensive, at the same distance, the result of its work is not much different from a router model with a price several times less. Despite the fact that the latter option is equipped with antennas located inside the device.

Changing hardware settings to improve wireless Wi-Fi signal strength

If you have and install equipment for accessing the Internet in a residential or office space, you can try to independently influence the signal strength of the wireless data network. The following tips will help you do this. First you need to decide on a way to solve the problem:

1. Reconfigure the router to strengthen the signal
2. Resort to additional devices or devices

Searching and changing the channel on the router

Step #1: search and change channel on the router. The active operation of your network can be influenced by the networks used by your neighbors. They place a heavy load on the channel on which your network depends. This can be found out if the device installed in your premises sees available neighboring networks for connection.

There is no way around this without experimentation. There are several options in this case:

• Set up any statistical channel
• Select channel Auto
• Using an additional program, select a free channel

What you choose must be fixed in the settings of the data transfer device (router).

There is no point in focusing on the instructions for replacing and installing the frequency range in this article. The easiest way is to use this useful article. It contains information about the essence of the channel and the method of finding an unloaded one. For routers of various models, the frequency range changes according to a certain method.

Network transition to 802.11N

Step #2: We switch our network to 802.11N operating mode. b/g/n (11bgn mixed) mode is the standard setting for wireless network operation. For routers with more than one antenna, you can force it to change. The choice in favor of 802.11N is characterized by new advantages of the router: improved Wi-Fi broadcasting, increased speed and expanded coverage area.

In the tab that opens, find the item Wireless mode and set the command only in N mode ( N only).

Below the described technique is clearly displayed using the example of an Asus router.

The stage ends by saving the settings and completely rebooting the device. If problems are detected while connecting the router, you must return to mixed operating mode.

Transmission Power Test

Step #3: We check the transmission power in the router settings. You can set the power of the Wi-Fi network yourself. Unfortunately, this option is not available for all devices and serves mainly to reduce power, but it is still worth paying attention to this fact.

For equipment from the manufacturer Asus, you need to use the tab with the item Wireless Network - Professional. At the bottom there is the following: “ Tx power transmission power control. The power indicator is adjusted by a scale with a unit of measurement - percentage. Visually it looks like this:

For Tp-Link routers, changing parameters is done using Wireless — Wireless Advanced. To determine the signal strength parameters, there is a point Transmit Power. The maximum power is indicated by the word High.

Additional devices to increase the active coverage area of ​​the wireless network

1. Installation repeater, or setting up a second router in amplifier mode.

This method differs from all others in its particular reliability and efficiency. But, along with this, it requires additional material costs for the purchase of a repeater. This device amplifies the signal and is installed in a place where Wi-Fi can still be detected, but its signal is already quite weak. It works on the principle of a repeater and transmits the network signal further. In the article, you can get acquainted with this small device in detail.

To perform repeater functions, you can use additional routers from manufacturers ZyXEL and Asus. It is possible to set the repeater mode in them, guided by the following methods:

1. Changing the router antennas to more powerful ones.

Using this method, the coverage of the Wi-Fi network can be increased, but only slightly. The result of changing antennas is not effective. Moreover, as in the first case, it requires additional investments. Yes, the price of removable antennas for a router is not that high, but is it worth spending money if it won’t do any good?

If you decide to change antennas, then you need to take the most powerful ones.

1. Buying a new router, switching to 5 GHz.

Since most routers operate at a frequency of 2.4 GHz, the device has an operating range of 5 GHz. will be operated much more efficiently. This is explained by the comparative freedom of this range and the absence of numerous interferences. As a result of this, an increase in speed and an expansion of the range of the wireless network.

You resort to switching to another band and purchasing a new router when the signal of your network is influenced by various other networks. Problems with low speed, constant “glitches” and loss of access can be solved by purchasing a new expensive router with a 5 GHz operating range.

Tip 1. Select the correct location for your router. It’s worth taking this advice, because most people have a router installed either in remote rooms or in the hallway. You should not expect efficient wireless network operation as a result.

The best place to place the router would be in the center of your home or office, and you should also be aware that walls interfere with the Wi-Fi network signal.

Tip 2. Homemade amplifiers for Wi-Fi antennas. The device can be made using available materials. Foil and tin are suitable for this. Many articles by folk craftsmen repeat this. In practice, you can place foil or a tin near the router so that the signal seems to bounce back and change direction, but this is not very effective. Moreover, from an aesthetic point of view, such a solution does not look very good.

Wi-Fi network performance is problematic in two ways. First: weak and unstable signal. Second: low data transfer speed. Both can be easily solved even by a person with a humanitarian mindset, if he reads our article or offers a box of beer to a neighbor who is an IT specialist.

The option with beer is, of course, better and revitalizes the Russian economy, and also provides a significant increase in GDP. But this option often has an incorrigible drawback: the neighbor IT specialist may not exist. And then, willy-nilly, you will have to read what we wrote for you here.

The most important. Make sure that at the center of your Wi-Fi network is a modern, full-fledged wireless router (aka router). The key word is modern. The fact is that communication equipment is developing as actively as the entire IT industry. Those standards, protocols and wireless transmission speeds that were the norm 5-7 years ago are now hopelessly behind. For example, not so long ago a channel of 50-60 Mbit/s was considered a decent option for the home, for the family, for show-offs. And now inexpensive devices for a couple of thousand rubles claim a theoretical 300 Mbit/s.

In his personal diaries, Captain Obvious has repeatedly noted that the main obstacle to a Wi-Fi signal is walls and partitions. In addition to walls, any shielding barrier containing metal can become a serious obstacle to the Wi-Fi signal - most often a mirror, an aquarium or a steel statue of Darth Vader. Demolition of all the walls in the apartment is the optimal solution to all your problems, but it is troublesome, yes. It’s easier to think about finding the optimal placement point for the signal source. Your wireless router should be as close to the center of the room as possible and should not lie on the floor, but should be placed at least a meter from the floor.

When you started searching for a network, you probably noticed more than once that there were a couple or even a dozen other people’s Wi-Fi signals walking around your apartment. For some reason, few people think about the fact that other people’s networks operate in the same frequency range as yours, and there is nothing good about that. According to standards, 13 frequency channels are allocated for Wi-Fi networks in Russia. We stole a screenshot of the configuration menu from the instructions for the popular ZyXEL Keenetic Lite router - you can see how in the “Network Client” mode the router shows channels occupied by neighbors. There are also separate programs that do the same thing, for example inSSIDer. All you have to do is study the resulting list, select the freest of 13 channels and set it as the default in the router.

Many craftsmen manually pump up router antennas by hanging tins, foil, and so on on them. In fact, the game is clearly not worth the candle - it is better to buy a suitable high-power antenna. There is a considerable assortment of them on Wi-Fi equipment websites, and some look very exotic. Antenna gain is specified in isotropic decibels (dBi). A standard antenna from a home router has a power of around 2 dBi, but finding and buying an antenna with a gain of 10-20 dBi is not a problem, and this radically solves the situation with signal availability! But it also makes sense to tame foil - recently a particularly virtuosic life hack with reflectors from , arousing increased interest, has been invented.

5

Many modern router models are equipped with a pair of antennas, and top models may have even more. Usually this provides a good signal, but if not, then changing two antennas at once will be expensive. In such a situation, it is better to install an additional signal distribution point in the apartment - such devices are called “repeaters” (Wi-Fi repeaters). They cost about the same as an inexpensive router and are easy to set up.

6

Often the problematic element in a home network is not the router, not the apartment layout, but the receiving device itself. You need to get two things off your chest once and for all. First: if you have a powerful computer for games and multimedia, it is still better to connect it to the network via a wired connection (there are a million reasons for this, and all of them are important). Second: if you are going to receive Wi-Fi via an adapter, choose not a tiny device the size of a fingernail (it is only suitable for gatherings in a coffee shop), but a receiver with a large antenna. Buying a Wi-Fi adapter with a heavy antenna also helps when your laptop receives a lousy signal, but in some corner of the room it is much better. You can plug a Wi-Fi adapter into your laptop and place its antenna in that lucky corner.

Owners of three-room apartments and large country houses often face the problem that the Wi-Fi router signal in certain rooms is too weak and does not allow normal use of the Internet. This is not surprising, since any waves tend to fade as they propagate, especially when there are too many obstacles in their path. Moreover, the quality of the signal is influenced not only by physical objects, but also by various types of noise created by electrical appliances. In this article we will talk about how to strengthen the signal of a Wi-Fi router at home using the simplest and most affordable methods.

Choosing the optimal location for a Wi-Fi router

You should start by determining the best location for your router. Obviously, the router should be located in that part of the apartment/house that will provide the maximum signal coverage area (radius). For example, the corner room of a three-room apartment is not suitable for this role, but the living room, usually located in the center, looks much more preferable. In a two-story house, you need to choose a place so that both tiers fall within the coverage area.

Bad location:

A good option:

This is ideal, but in reality it is also necessary to take into account the amount and strength of interference encountered along the signal path. Both physical obstacles (walls, partitions, etc.) and wireless devices operating at the same frequency (2.4 GHz) (microwave oven, baby monitor, cordless phone, Bluetooth devices, etc.) weaken the signal and negatively affect the signal quality metal objects, glass, mirrors.

Failed scheme:

Best option:

Strengthening the signal using manual channel selection

We have already said that various types of wireless devices located in close proximity to your Wi-Fi router can seriously degrade its signal. These same devices also include other routers, of which there may be a great variety in the neighborhood. There are special utilities and applications that allow you to scan surrounding wireless networks for the channels used and their congestion. One of the most popular programs of this kind is inSSIDer. Let's download it from the Internet and study the functionality.

Let us immediately note that the inSSIDer application is best suited for desktop computers, laptops and tablets. Smartphones have their own programs that are easy to find and install. So, launch the utility, select the adapter type (in our case, D-Link DWA-125 is used) and click the “Start Scan” button. Based on its results, all Wi-Fi networks detected nearby will be displayed with full characteristics - MAC address, name (SSID), channel involved and signal strength (RSSI). We are primarily interested in channels here, but before we start working with them, it wouldn’t hurt to figure out what they are.

Modern Wi-Fi routers can operate in two frequency bands – 2.4 GHz and 5 GHz. The 2.4 GHz frequency (actually the range 2.4-2.4835 GHz) is the most common and is supported by most routers offered today. For this frequency band in the Russian Federation, channels 1-13 are reserved. Only the latest models of Wi-Fi routers can operate at the 5 GHz frequency (5.15-5.35 GHz), using channels 34-64. So, in the table of the inSSIDer program we can see which channels are used by nearby routers (the “Channel” column) and what the signal strength is (the RSSI column). The lower the RSSI number, the better the signal. For convenience, below are the graphs – Channel Graph and Time Graph.

The first trapezoid graph displays channels and signal strength.

The second graph shows the timing diagram of the signal.

The optimal situation is when on the “time graph” the signal of your Wi-Fi network does not intersect with other networks. If this happens, interference may occur and it may be worth experimenting with the channels. To do this, you need to go to the router settings.

As an example, let's take the TP-Link TL-WR841N router that we cited. We go to the administrative panel of the router, and then to the section Wireless Mode - Wireless Settings. Here, in the drop-down list, you can manually set one of 13 channels (the default mode is “Auto”). Select the channel that is not used by neighboring routers and, accordingly, is less loaded. After changing the settings, save them and restart your device.

Rescan your wireless networks and see how the Wi-Fi signal strength has changed. In any case, you will have to experiment with the settings yourself to achieve the best configuration.

Switching to another frequency

If your router can operate not only in the 2.4 GHz band, but also at the 5 GHz frequency, then it is advisable to switch to the second, higher frequency. As a rule, it is less busy.

Increasing the transmitter power of a Wi-Fi router

Most network devices allow you to change the power of the signal transmitter in the same web interface. You can set this parameter for the TP-Link TL-WR841N router in the section Wireless Mode - Advanced Settings. If the power is set to “Medium”, then change the value to “High”. This action should strengthen the router's Wi-Fi signal.

Changing the direction of the antenna

Improving signal quality can be achieved by simply changing the angle of the router antenna. True, there is, of course, no talk of any serious strengthening here. But it is quite possible to provide good coverage for a specific area of ​​the room, in which the Wi-Fi signal will mainly be received. Rotate the antenna in different directions, measuring the signal intensity, and find its best position.

It is curious that the correct position of the Wi-Fi router antennas depends on their number. And this is due to the peculiarities of the propagation of wireless network waves. So, if there is only one antenna, it is recommended to position it perpendicularly. If your router has two antennas, then it is better to place them at an angle of 45 degrees. However, these are only general tips; each specific case has its own recipe for the optimal direction of the antennas.

Installing a more powerful antenna

Many router models have replaceable antennas, which makes it possible to install an emitter with a higher gain (dBi). In this case, you need to understand that in fact the total intensity of the transmitted signal will not increase, since the same fixed power (maximum 100 mW) will be supplied to the antenna. It’s just that antennas with a high dBi rating are capable of concentrating power in a certain direction, significantly improving the signal quality in some areas and worsening it in others. Those. The benefits of using more “powerful” antennas can only be obtained if all signal receivers are located in one place.

Using a signal amplifier (repeater)

One of the most effective ways to expand the coverage area of ​​a wireless Wi-Fi network is to use a so-called repeater (also known as a repeater, also known as a repeater). This is a portable device that is sold in any computer store or home appliance hypermarket. The repeater must be located in that part of the house/apartment where the signal from your Wi-Fi router is still available, but it is already quite weak. The repeater receives this signal, amplifies it and transmits it further. This ensures a significant increase in the area of ​​stable and reliable reception.

The advantages of a repeater include the fact that it allows you to easily scale the coverage area of ​​your wireless network. In this case, the network broadcast by the repeater is a complete copy of the network created by the original Wi-Fi router. Among the disadvantages, we note the decent cost of the repeater, comparable even to the price of some routers. By the way, the routers themselves can also perform the function of strengthening the Wi-Fi signal, although not all models have this capability. If you have an unused router sitting somewhere collecting dust, then you can adapt it as a repeater, after first making sure that it has this functionality.

Updating Wi-Fi router firmware

In certain cases, reflashing the router with installing the latest version of the software can help improve the Wi-Fi signal. This procedure may vary depending on the model, so it is recommended that you look for instructions specifically for your router.

Results

We have listed all the main ways to boost a Wi-Fi signal. This article does not address the situation when Internet speed drops due to unauthorized connection of third-party users to your network. To avoid this, set a strong password for your Wi-Fi. Sometimes the quality of wireless communication deteriorates due to a malfunction of the router or simply after a long period of continuous operation. In this case, a simple reboot usually helps.

We hope that the information provided will help you correctly configure your home Wi-Fi network and ensure reliable signal reception within the maximum radius.

Nowadays it is difficult to find a smartphone, laptop or tablet that does not support wireless networks - Wi-Fi. Not only them, but also many modern household appliances can be connected to the network. Even multicookers are connected to Wi-Fi, so it is important to ensure good reception in all corners of the apartment or house. But a significant problem is the excess of wireless networks. In this article we will look at how to strengthen the signal of a Wi-Fi router with your own hands.

Reasons for a bad signal

Before we consider ways to strengthen the signal, we will talk about the reasons for its fading. The main ones include:

1. Wall material. The most common problem is a significant difference in signal levels in different rooms of an apartment with concrete walls.
2. Router location. In order for the Wi-Fi signal to be uniform over the entire intended coverage area, you need to place it in a place equidistant from all the far corners of the coverage area. Otherwise, every wall, cabinet, shelf or other piece of furniture will degrade the Wi-Fi signal.
3. Antenna gain. Cheap wifi routers usually have one 3 dbi antenna installed - this is a rather weak option.
4. Incorrect router settings.
5. Bad Wi-Fi receivers.
6. Many networks running in parallel.

How to strengthen Wi-Fi

Now that we already know what leads to deterioration in the propagation and reception of a Wi-Fi signal, let's look at each problem and its solution separately. To strengthen Wi-Fi you need:

1. Find the ideal place to install your router.
2. Set its operating mode.
3. Replace the antennas with more powerful ones.
4. Install reflectors.
5. Install repeaters or strengthen the network with another router.

Correct location of the router

If you want to boost your Wi-Fi signal, before you do anything, make sure your router is positioned correctly and minimize sources of interference and reflections. The router must be located so that a normal signal level is provided in each room.

If you have chosen the optimal place, but did not get the desired results, pay attention to the recommendations:

1. Microwave ovens, remote controls and other equipment operating at high frequencies, in particular 2.4 GHz. If such equipment is located nearby, move either it or the router.
2. Neighborhood Wi-Fi. You can improve the situation slightly if you install the router in a place where the signal level is the lowest. You can determine this if you walk around your apartment with your smartphone and pay attention to the level of signal reception from your neighbors. You need to install the router where all signals will have the lowest level. The Wifi Analyzer program for Android will help you with this.

Configuring the router correctly

Before you run to the store for a new antenna, Wi-Fi receiver or router, let's go to the settings and check what parameters are set there. To do this, you need to enter the address of the router in the address bar of your browser; it is usually indicated on a sheet pasted on its bottom. Most often this is 192.168.0.1 or 192.168.1.1

First of all, you need to look at the standard in which it operates. In different models of Wi-Fi equipment, settings and web interfaces differ significantly from manufacturer to manufacturer. Therefore, we will try to give general recommendations.

You need to connect to the router via the web interface and find the list of modes. Their names begin with the numbers 802.11, followed by letters, for example, 802.11b/g/n. To strengthen the router’s Wi-Fi signal, you need to select the item with the type name:

802.11n only

You should already see an increase in the Wi-Fi signal.

After this, you can try to increase the transmitter power; to do this, look in the settings for an item called transmit power type. It can be specified either as a percentage or as:

• High;
• Medium;

In any case, you need to set the maximum possible percentage value closer to 100% or High.

We have completed the basic settings for signal amplification. Now let's check the computer. If you have a laptop, check your power mode settings. In power saving mode, the signal gain from the built-in receiver is reduced, which causes problems with unstable connections and reduced speed. Set the mode to "normal" or "high performance".

Duplicate the network

If you need Wi-Fi reception at 100 meters or more, then you won’t achieve this with a regular router. Their coverage range also depends on the number of obstacles, transmitter power and antenna gain. On average you can count on 30-50 meters. The easiest way to strengthen the signal is to install a Wi-Fi repeater. This is a signal repeater that simply plugs into an outlet.

The outlet should be located in an area where the signal is not too bad, but not next to the router. You can amplify the signal with one or two repeaters to obtain a larger coverage area. But you need to configure it - select a network and enter a password for it. This reception distance is often required in a private home in order to have a signal in the yard.

The second way is to increase coverage with another router. Some models support operation in repeater mode. This can also be done by connecting the first and second routers with a simple network cable with rj-45 type plugs, as you would do when connecting the cable to a computer’s network card.

Upgrading or changing the antenna

If the router does not have an antenna, then the only method of amplification is software; we have already considered the optimal settings. The next option to boost your Wi-Fi signal is to experiment with antennas.

Experiments could be as follows:

If you are a fan of constructing something, then a biquad antenna can help to strengthen the signal for Wi-Fi reception at 200 meters; its drawing is shown in the figure below:

And this antenna, a Wi-Fi gun, will help transmit the Internet over 1 km or more (depending on the installation height and the accuracy of the signal direction). Its developer claims that he managed to achieve reception at a distance of up to 10 km.

In this way, it is possible to organize communication between houses remote from each other, or an apartment and a dacha, for example.

Important! It is not correct to talk about the range of the antenna. This figure depends not only on its design, but also on the installation location, the number of obstacles, and, importantly, the antenna of the device that will receive the signal. If in the field a regular router with a standard antenna can transmit a signal over 50-100 meters, then in concrete buildings there are problems with communication when moving to the next room.

We looked at the main available methods to strengthen the signal of a Wi-Fi router, as well as increase the coverage area. If you follow all the recommendations, you will achieve an improved signal, but you need to take into account the quality and serviceability of all equipment. For example, if after all the manipulations done, the quality of signal reception on the phone leaves much to be desired, it may be due to a weak Wi-Fi module and built-in antenna.

Materials

A WiFi antenna is an excellent solution for anyone who has tried to organize wireless Internet distribution at home or at work, but has encountered the problem that the router signal is not enough to use it without problems in some remote room. However, this is not the fault of your router, but of the antenna - built-in or external, which was included in the package. One of the most effective solutions for strengthening a wireless signal is a directional external wifi antenna. They come in several types and types that are used depending on your needs. And it is precisely this diversity that we will now understand.

External passive antenna for WiFi router

First of all, it should be noted that a passive antenna for a wifi router, that is, which does not have its own power supply from the mains, does not amplify the signal, but only directs its spectrum for more reliable reception. The power of this “amplification,” also called directional gain, is measured in decibels (dBi). Many models of routers and adapters are already equipped with small external antennas, but their power does not exceed 3-5 dBi, which will not significantly improve the range of the wireless signal.

Therefore, external wifi antennas are used for this. They have two types of separation - for outdoor or indoor use, as well as omnidirectional and narrow directional.

Outdoor and indoor antenna use

• Outdoor antennas are those that are designed to work outdoors. They are protected from the effects of precipitation and sunlight and have special fastenings for installation on the wall of a building. They will be needed if you want to create a secure reception area in the yard or for communication between neighboring houses.
• Indoor antennas - for indoor use. For example, if your router is installed in a remote or closed place, then such an antenna can be connected with a cable to the antenna connector of the router and brought to the center of the room.

Directional wifi antenna

This is the most used type. An antenna that directs a wifi signal in a certain direction, for example, from a house to a personal plot, or to the balcony of a neighboring house, if we are talking about an external directional wireless antenna. Their range of action can be from one to several km. The main thing is that the reception source is in direct line of sight.

Internal directional wifi antennas for a router will be useful if, for example, it hangs on the wall. To prevent radiation from reaching the wall, you can connect it to the router and point it towards your desktop, on which the laptop is placed. Or vice versa, point the antenna at the partition so that the signal passes through it more confidently, providing stable communication in the next room. A very successful design of such an antenna is a panel rectangle that emits a radio signal in one direction.

Please note that it is connected to the router not via USB, but instead of the attached antenna that came with the router. Accordingly, if it was non-removable, then it will not be possible to replace it with another one.

There are also compact models that are suitable for both indoor use and outdoor mounting.

An omnidirectional wifi antenna is distinguished by the fact that it evenly distributes the signal around itself. The disadvantage is that the signal may be distorted by emissions from other electronic devices located in the apartment, or by external radio waves if it is installed outdoors. These antennas look like a vertical rod. External ones can be installed on the roof of the house or on a vertical pole dug into the ground. Internal - on a table or shelf, as close as possible to the expected center of the desired reception area.

The external wifi antenna for the router is attached in the same way in place of the standard one to the same connector.

Another interesting type of indoor omnidirectional wifi antennas is for ceiling mounting. They look like a lamp. Its peculiarity is that there is a dead zone directly under the antenna and it needs to be hung exactly in the place where the signal is not needed, and reliable reception will begin only at a short distance from it.

Installing a WiFi antenna

When installing any type of antenna, it is necessary to consider where the signal source is coming from. In modern urban development, it can greatly lose in efficiency both due to the density of houses and the materials from which they are made. I provide a table from which you can roughly understand how much this or that material degrades the performance of the access point. The most important parameter here will be “Effective distance” (ED). It must be calculated as follows. For example, the characteristics of the router indicate that it operates at 400 meters. it is understood that with direct visibility. You are separated from it by an interior wall with an ER of 15%. We calculate: 400 m multiplied by 15% and we get 60 meters. That is, through a 15-20 cm wall, the router will “shoot” only 60 meters. Moreover, if you attach an antenna of 15-20 decibels to it, this loss will be neutralized.

Homemade wifi antenna with your own hands

You can make a directional Wi-Fi antenna with your own hands. Watch a video on how to make a homemade structure from an ordinary beer can.

I can’t say for sure whether this is true or false - I think there is some reason. By analogy with this popular example, you can also make a directional antenna from an omnidirectional one. To do this, it is enough to attach a reflective screen behind it, for example, from the same sheet of foil. Below are some interesting options for making an antenna with your own hands that you can use.
