Today, wireless communication is the most demanded among the latest technologies. If the user is tired of looking around the apartment for a place where excellent Internet is available, you can try to strengthen the signal of the wi-fi router with your own hands.
Methods for improving the work with a wireless network are combined into three main groups: software settings on the equipment, changing the location of communication devices, and hardware amplification. The best effect is given by the third way, which has several embodiments.
Interference. Wireless communications can weaken any electrical appliances. Here you need to amplify the wi-fi signal using a second router. Another option is to place the devices away from each other. You can strengthen the wireless Internet by changing the location of the router. Install it in a free, open space.
Often this action helps to improve the speed of the Internet. An in-depth study is required to identify the problem. Perhaps the old firmware has overheated. Rebooting it once a day helps to strengthen the signal of the Wi-Fi router in the apartment. It is carried out automatically or manually.
DD-WRT flashing is also used as a wi-fi router signal booster. By performing this action, we get additional functions, the operation of the router is noticeably improved.
Installing the DD-WRT Firmware
Internet speed is affected by:
- downloading movies;
- participation in online games;
- sitting in video chats.
If this is your case, configure "QualityofService or QoS". Thus, prioritize the more necessary programs.
Set a password on the router. This action will protect the Internet from connecting neighbors to it.
Homemade screen. The additional design of the router will help to make the wi-fi signal stronger. Take a can of beer, set it as a reflector, directing the waves from the amplifier in your direction. This simple solution is considered one of the workable ones. Installing the screen will not affect the radiation of the device. The energy will be directed into a limited space and create a Wi-Fi router signal amplifier.
Homemade screen from a jar for a router
Channel change. When neighbors share the same connection, the radio waves of the routers are able to overlap each other. The speed drops noticeably. You can increase the wi-fi signal by changing the data transfer channel. Change settings on your computer. When there is a "power saving mode", Wi-Fi does not accept 100%. Switch the power mode. Find "signal strength", set to maximum, save this parameter.
Setting signal strength
As you can see, there are many tips for strengthening Wi-Fi with your own hands. What exactly each user chooses depends on the operation of his network, capabilities, desires.
Hardware amplification
The wi-fi network depends directly on the distribution power, and on the propagation conditions. The presence of barriers with a screen effect between the router and the receiving device can negate the positive characteristics of the first. The reverse is also true. Therefore, increased range and improved quality are achieved in different ways.
Using a repeater to amplify the wi-fi signal
Powerful wifi antenna
How to enhance the distribution of a wi-fi router using additional devices:
- organize a system of repeaters or repeaters;
- connect the antenna through a cable to move to the most advantageous place for signal propagation;
- use an amplified antenna for a wi-fi router;
- buy a powerful router. This method is more expensive than others, but effective and simpler. There is one catch - routers over 100 mW cannot be sold as household appliances.
Devices such as a repeater and an antenna to amplify the signal of a wi-fi router will help expand the coverage area when a convenient location is not available. A replaceable antenna for amplifying the wi-fi signal will change the shape of the coverage area, make it wider, but smaller in height. The gain will be several meters in range, not suitable for providing the Internet at different levels.
DIY antenna
How to strengthen the antenna of a wi-fi router? The simplest trick is to install the screen on the side opposite to the location of the receiver devices. This will improve signal propagation in the desired direction.
You can make a do-it-yourself wi-fi signal repeater from a second router if it has the WDS function. Special repeaters are powered from the mains and in operation are not much different from a router.
The advantage of this method is that a router with a wi-fi signal amplifier makes it possible to bypass obstacles that create an impenetrable screen. In a large house, installing repeaters will provide coverage in the most remote places.
Reinforcement with an adapter
To get a satisfactory Internet experience through wi-fi, there is special equipment - a wi-fi adapter. The device picks up a wireless connection, and connects via a USB connector or a PCI slot.
To solve the problem with the quality of communication, it is easiest to initially purchase a powerful adapter. The size of the antenna is directly proportional to the quality of information reception, so when buying, you don’t even have to study the characteristics. Sometimes the device is already available, but the power of action is not enough. There are two options here: connect via cable to a computer and amplify the wi-fi signal on the modem.
In the first case, the cable will allow you to place the adapter in the zone of the best distribution of the network. The only limitation is the length of the wire, which is difficult to find more than three meters.
To amplify the signal of the wi-fi adapter with your own hands, another antenna is purchased. But it will help if it was originally provided on the original device.
Most modern equipment has a built-in modem, for which these methods will not work. But there is a device for amplifying the wi-fi signal, which is connected via USB to computers and laptops.
Depending on the relative position of the router and gadgets, certain methods are applicable. It is important to determine the causes of a poor signal before choosing a specific type of amplification. A variety of equipment will allow you to choose the best solution for each specific case.
Gain without antenna
Ways to amplify the signal. This problem can be solved using a number of tools that enhance the signal. They are simple, do not require any additional effort to make your router work better.
How to amplify the signal of a wi-fi router without an antenna? Here you need to know that the operation of the router is affected by various interference from other devices: a cell phone, a microwave oven, a computer. These factors must be taken into account, but it is possible to increase the signal by applying some methods.
Signal amplification without antenna
How to amplify the signal of a wi-fi router Rostelecom without an antenna:
- put the router in the highest place in the house (for example, on a closet);
- do not allow the router to stand next to metal structures - refrigerators, safes, cabinets, etc.;
- if the computer or laptop does not have a very powerful wi-fi card, it must be replaced with a USB adapter;
- put a repeater between the router and the computer;
- change the signal transmission channel, for this, select a more suitable signal in the router configuration;
- eliminate radio interference as much as possible.
The listed methods are the main and most common. In addition to these methods, it is recommended to update the drivers.
How to replace the antenna on the router? On routers, the antennas are designed so that they transmit a signal in all directions at once. In such cases, part of the signal will disappear, the power of the router will work by half. Then you need to replace the antenna with an increased signal factor. To create a parabolic surface that directs the signal in the right direction, you can take an aluminum can as a material.
It will be possible to amplify the signal from the Rostelecom router if you correctly install the router in the apartment, directing its antennas at 45 ° angles and setting the 802.11 B / G mixed mode. An effective means of amplifying the signal is to install an access point in any part of the house.
A weak WiFi signal is an actual problem for residents of apartments, country houses and office workers. Dead zones in the WiFi network are characteristic of both large rooms and small apartments, the area of \u200b\u200bwhich is theoretically capable of covering even a budget access point.
The range of a WiFi router is a characteristic that manufacturers cannot unequivocally indicate on the box: many factors affect the WiFi range, which depend not only on the technical specifications of the device.
This article provides 10 practical tips to help eliminate the physical causes of poor coverage and optimize the range of a WiFi router, it's easy to do it yourself.
The radiation of an access point in space is not a sphere, but a toroidal field resembling a donut in shape. In order for WiFi coverage within one floor to be optimal, radio waves must propagate in a horizontal plane - parallel to the floor. For this, the possibility of tilting the antennas is provided.
Antenna - the axis of the "donut". The angle of signal propagation depends on its slope.
When the antenna is tilted relative to the horizon, part of the radiation is directed outdoors: dead zones form under the “donut” plane.
A vertically mounted antenna radiates in a horizontal plane: indoors, maximum coverage is achieved.
On practice: Mounting the antenna vertically is the easiest way to optimize indoor WiFi coverage.
Place the router closer to the center of the room
Another reason for the appearance of dead zones is the poor location of the access point. An antenna radiates radio waves in all directions. In this case, the radiation intensity is maximum near the router and decreases as you approach the edge of the coverage area. If you install an access point in the center of the house, then the signal will be distributed across the rooms more efficiently.
The router, installed in the corner, gives some of the power outside the house, and the far rooms are on the edge of the coverage area.
Installation in the center of the house allows you to achieve a uniform distribution of the signal in all rooms and minimize dead zones.
In practice: Installing an access point in the “center” of the house is far from always feasible due to the complex layout, the lack of outlets in the right place, or the need to lay a cable.
Provide line of sight between router and clients
WiFi signal frequency - 2.4 GHz. These are decimeter radio waves that do not go around obstacles well and have low penetrating power. Therefore, the range and stability of the signal directly depend on the number and structure of obstacles between the access point and clients.
Passing through a wall or ceiling, an electromagnetic wave loses some of its energy.
The amount of signal attenuation depends on the material that the radio waves pass through.
* Effective distance is a value that determines how the radius of a wireless network changes in comparison with open space when a wave passes through an obstacle.
Calculation example : WiFi 802.11n signal extends in line of sight to 400 meters. After overcoming a non-permanent wall between rooms, the signal strength decreases to a value of 400 m * 15% = 60 m. The second wall will make the signal even weaker: 60 m * 15% = 9 m. The third wall makes signal reception almost impossible: 9 m * 15 % = 1.35 m.
Such calculations will help to calculate the dead zones that occur due to the absorption of radio waves by walls.
The next problem in the path of radio waves: mirrors and metal structures. Unlike walls, they do not weaken, but reflect the signal, scattering it in arbitrary directions.
Mirrors and metal structures reflect and scatter the signal, forming dead zones behind them.
If you move interior elements that reflect the signal, you can eliminate dead zones.
In practice: It is extremely rare to achieve ideal conditions when all gadgets are in direct line of sight with the router. Therefore, in a real home, each dead zone will have to be eliminated separately:
- find out what interferes with the signal (absorption or reflection);
- think about where to move the router (or piece of furniture).
Place the router away from sources of interference
The 2.4 GHz band does not require a license and is therefore used for the operation of household radio standards: WiFi and Bluetooth. Despite the low bandwidth, Bluetooth is still able to interfere with the router.
Green areas - stream from WiFi router. Red dots are Bluetooth data. The proximity of two radio standards in the same range causes interference that reduces the range of the wireless network.
The microwave oven magnetron emits in the same frequency range. The intensity of the radiation of this device is so high that even through the protective screen of the furnace, the radiation of the magnetron is able to “illuminate” the radio beam of the WiFi router.
The radiation of the magnetron of the microwave oven causes interference interference on almost all WiFi channels.
On practice :
- When using Bluetooth accessories near the router, enable the AFH parameter in the latest settings.
- The microwave is a powerful source of interference, but it is not used as often. Therefore, if it is not possible to move the router, then just while preparing breakfast, you will not be able to make a Skype call.
Disable support for 802.11 b/g modes
In the 2.4 GHz band, WiFi devices of three specifications work: 802.11 b / g / n. N is the newest standard and provides more speed and range than B and G.
The 802.11n (2.4 GHz) specification provides longer range than the legacy B and G standards.
802.11n routers support previous WiFi standards, but the mechanics of backwards compatibility is such that when a B/G device, such as an old phone or a neighbor's router, appears in the coverage area of an N-router, the entire network is switched to B/G mode. Physically, there is a change in the modulation algorithm, which leads to a drop in the speed and range of the router.
In practice: Switching the router to “pure 802.11n” mode will definitely have a positive effect on the quality of coverage and bandwidth of the wireless network.
However, B/G devices will not be able to connect via WiFi. If it is a laptop or TV, they can be easily connected to a router via Ethernet.
Choose the optimal WiFi channel in the settings
Almost every apartment today has a WiFi router, so the density of networks in the city is very high. The signals of neighboring access points overlap each other, taking energy from the radio path and greatly reducing its efficiency.
Neighboring networks operating on the same frequency create mutual interference interference, like circles on the water.
Wireless networks operate within range on different channels. There are 13 such channels (in Russia) and the router switches between them automatically.
To minimize interference, you need to understand which channels neighboring networks operate on and switch to a less loaded one.
Detailed instructions for setting up the channel are presented.
In practice: Choosing the least loaded channel is an effective way to expand the coverage area that is relevant for residents of an apartment building.
But in some cases, there are so many networks on the air that not a single channel gives a tangible increase in WiFi speed and range. Then it makes sense to turn to method number 2 and place the router away from the walls bordering neighboring apartments. If this does not bring results, then you should think about switching to the 5 GHz band (method No. 10).
Adjust the transmitter power of the router
The transmitter power determines the energy of the radio path and directly affects the range of the access point: the more powerful the beam, the farther it hits. But this principle is useless in the case of omnidirectional antennas of household routers: in wireless transmission, data is exchanged two-way and not only clients must “hear” the router, but vice versa.
Asymmetry: the router “reaches out” to the mobile device in the back room, but does not receive a response from it due to the low power of the smartphone’s WiFi module. The connection is not established.
In practice: The recommended transmitter power is 75%. It should be increased only in extreme cases: the power turned out by 100% not only does not improve the signal quality in distant rooms, but even worsens the reception stability near the router, because its powerful radio stream "clogs" the weak response signal from the smartphone.
Replace the standard antenna with a more powerful one
Most routers are equipped with standard antennas with a gain of 2 - 3 dBi. The antenna is a passive element of the radio system and is not capable of increasing the power of the stream. However, increasing the gain allows you to refocus the radio signal by changing the radiation pattern.
The higher the antenna gain, the farther the radio signal travels. At the same time, a narrower flow becomes not like a “donut”, but like a flat disk.
There is a large selection of antennas for routers with a universal SMA connector on the market.
In practice: Using a high-gain antenna is an effective way to expand the coverage area, because along with signal amplification, the antenna sensitivity increases, which means that the router begins to “hear” remote devices. But due to the narrowing of the radio beam from the antenna, dead zones appear near the floor and ceiling.
Use signal repeaters
In rooms with a complex layout and multi-storey buildings, it is effective to use repeaters - devices that repeat the signal of the main router.
The simplest solution is to use an old router as a repeater. The downside of this scheme is that the throughput of the child network is halved, since, along with client data, the WDS access point aggregates the upstream from the upstream router.
Detailed instructions for setting up a WDS bridge are presented.
Dedicated repeaters are free from the problem of bandwidth cuts and are equipped with additional functionality. For example, some Asus repeater models support roaming.
In practice: No matter how complex the layout is, repeaters will help deploy a WiFi network. But any repeater is a source of interference interference. With free air, repeaters do their job well, but with a high density of neighboring networks, the use of relay equipment in the 2.4 GHz band is impractical.
Use the 5 GHz band
Budget WiFi devices operate at 2.4 GHz, so the 5 GHz band is relatively free and has little interference.
5 GHz is a promising range. Works with gigabit streams and has an increased capacity compared to 2.4 GHz.
In practice: “Moving” to a new frequency is a radical option that requires the purchase of an expensive dual-band router and imposes restrictions on client devices: only the latest gadget models work in the 5 GHz band.
The problem with WiFi signal quality is not always related to the actual range of the access point, and its solution generally comes down to two scenarios:
- In a country house, it is most often required in free air conditions to cover an area that exceeds the effective range of the router.
- For a city apartment, the range of a router is usually sufficient, and the main difficulty is to eliminate dead zones and interference.
The methods presented in this material will help to identify the causes of poor reception and optimize the wireless network without resorting to replacing the router or the services of paid specialists.

Let's make a final digression. One of our customers, having familiarized himself with our device, was very surprised by its possible application and wrote to us - you have made equipment for WiFi theft!
Of course, an attacker can use "WiFi Agent" for illegal purposes. But, with the same success, one can blame the sellers of axes that the new "Raskolnikov" will buy an ax and attack the old pawnbroker. And the sellers of dishes are generally accomplices of criminals. Here and knives, and rolling pins, and a terrible tool - a cast-iron frying pan.
In light of the latest laws being passed, it should be noted that our device does not contain any cryptographic encryption tools and is not a WiFi router. USB WiFi adapter with directional antenna "WiFi Agent" does not use any means to hack other people's networks and does not make the process of "theft" one iota easier than a standard laptop WiFi adapter.
We believe that the issue of using any devices within the law is the direct responsibility of the consumer. Therefore, of course, when performing any action, it is always necessary to remember the legal side of the issue.
We recommend using "WiFi Agent" in situations where the regular WiFi adapter of your laptop or PC receives a WiFi network signal with a low level, as well as in cases where you need to use your WiFi network while being at a great distance from the router.

WiFi technology is gaining momentum and becoming even more popular. Therefore, modern appliances are already immediately produced with a built-in Wi-Fi module, for example: refrigerators, kettles, TVs. Manufacturers are trying to make a person's life more comfortable and carefree. Going into any cafe, shop, club, you can easily connect your phone or tablet to the World Wide Web, all thanks to Wi Fi wireless technology. Also, you probably have many devices at home that support Wi-Fi. So that you do not have to drag a bunch of wires with you, it is enough to buy a router that will distribute the Internet.
But many are faced with a problem - a weak WiFi signal, as a result, an underestimated Internet speed. Therefore, we decided in this article to help you and tell you in detail how to strengthen the wifi signal using various methods.
Choosing the location of the router
When you decide to install a router in your home, pay special attention to the question, where is the best place to place it?
- Try to keep your router as close to the center of the house as possible. So that radio waves propagate evenly throughout the house.
- The router is best placed near doorways or windows. Then the wireless signal will be less attenuated.
- Do not place the router in the kitchen near the microwave oven. Wi-Fi operates at a frequency of 2.4 GHz, and the oven also operates at the same frequency. Therefore, they interfere with each other. When you turn on the microwave oven, the router may even hang.
- Do not install the router in iron boxes or boxes. The signal passes through metal barriers the worst.
- It is undesirable to place the router in the children's room or bedroom. There is still no consensus on how harmful radiation from a router is for a person. Therefore, away from sin, it is better to put it in the corridor.
- Do not place two routers in the same room. If there is no other option, then at least spread them across different channels. For example: put one channel 1, and put the second channel 12.
Using programs, we strengthen the Wi-Fi signal
Usually, after buying any equipment, people do not really like to look at the instructions that come with the device. The router is no exception, few people pay due attention to setting it up. Usually, the entire setup ends after entering the password for the Wi-Fi network and SSID, all other settings are left by default. Therefore, in the process of using wireless Internet, all sorts of problems arise, such as: a weak signal,. Let's figure out why this happens and how you can strengthen the WiFi signal
Choosing a WiFi radio channel
Having put the router in the apartment, many did not think that the neighbors below, above, on the side, also installed a router. Why is that bad, you ask? And the fact that there is a high probability that the channels in which the routers will work can intersect. Many routers default to channel 6. Just imagine, all the neighbors, like you broadcast on channel 6, the result of such work is a decrease in the signal level and a drop in bandwidth.
InSSIDer utility
Therefore, during the setup process, do not be lazy and download a utility that will help you decide on the choice of a channel for broadcasting. For example, let's take a program that is easy to use and popular - InSSIDer. This utility is able to scan the air well and give out a large amount of useful data, thanks to which you will decide which channel is most suitable for you.
Acrylic WiFi App
Also less popular acrylic wifi. There is a free version and a paid version that adds advanced features. The application can scan channels in all modes in the 2.4 and 5 GHz bands, competently analyzes the distribution of channels.
Low transmitter power
The ability to adjust the power of the Wi-Fi transmitter is not provided on every router. In this case, another firmware can help you. To search for it, you will have to spend a little time, and no one guarantees 100% success after installation. So it's up to you to decide.
Models that have this function can increase the power to improve the signal, now we'll tell you how to do it. Often the default is low power, so go to the router settings, in the menu you need to find the item " Transmit Power". We select the maximum one hundred percent or the value " High (Nigh)." After that, your Wi-Fi signal will be amplified.
Choose Wi-Fi Standard IEEE 802.11n
There are few standards for Wi-Fi. To date, this is 802.11-a-b-g-n-ac, the last AC is not in every router. It is believed that the fastest standard is 802.11n, it has more than all the other coverage radius that it covers. But we must not forget that not all Wi-Fi devices support this standard. Whether your device supports the 802.11n standard is easy to find out. On the router, you need to configure this standard in the settings. We take a phone or tablet and scan the radio. You will see if you can see your network or not.
To configure, go to the main menu of the router. Find the " Wi-Fi" tab, then select " basic settings”, you will see the line “ Wireless mode» next to it, you can select the operating mode. Don't forget to save your settings and reboot.
Using the more advanced 5 GHz band
Using the 5 GHz band, you will be able to pump the speed much more than with the 2.4 GHz band. This is due to the fact that a large number of devices operate at a frequency of 2.4 GHz, while, of course, the radio air is heavily clogged and interfere with one another. But the frequencies of 5 GHz are used much less often, there is less noise, the bandwidth is greater. The only plus on 2.4 GHz is that the wifi signal amplification is stronger and breaks through any obstacles better. So you choose which range to use.
Increasing the signal with changes in Windows
This section is more suitable for users who have Wi-Fi on a laptop. Often, manufacturers by default set laptops in the power consumption section to the “ Energy saving". Because of this, the Wi-Fi adapter in the computer reduces performance. To fix this, you need to change the mode to " Balanced or High. With this mode, you can catch a signal from a greater distance.
How to remove power limits in the router
In most countries, routers have introduced power limits up to 100 mW. There are only a few countries in which there are no restrictions, one of them is Bolivia, thanks to this there is a loophole with which you can increase the transmitter power.
- Install Kali Linux or just Linux.
- In the terminal, enter the commands:
ifconfig wlan0 down
macchanger -r wlan0
iw reg set BO
iwconfig wlan0 txpower 400mW
ifconfig wlan0 up
A value of 400 mW means power, you can start with 200 mW so as not to burn the transmitter.
You can also try the second way to increase power. To do this, you need to write the wl -i wlan0 txpower 100 command, where 100 is the power you set, and wlan0 is your adapter.
Increasing the signal by improving the Wi-Fi antenna
If there is an opportunity and finances, then you can simply replace the antenna on the router with a more powerful one. For example, a standard antenna usually has a gain of 4-5 dBi, in which case it will not be difficult to find an antenna in stores to amplify the signal with a large dBi coefficient.
But when there is little money or just want to save money, a beer can will come to the rescue! It didn't seem to you, you read everything correctly, a beer can. This is the easiest and most proven way to slightly increase the signal at home.
To create a Wi-Fi signal reflector, you need to cut off the entire bottom and do almost the same with the top of the can, unlike the bottom, we don’t cut it a little from the top. Then we cut the jar lengthwise, we get a sail, which we put on the antenna. You're done, you've learned how easy it is to improve your signal.
Boost your WiFi signal with a repeater
The repeater will help to amplify the signal. You can buy both in the online store and in a regular store, it all depends on your desire. Their variety is large, so look at the characteristics and choose the right one. After purchase, you need to connect it to your wireless network in order for the repeater to increase its range.
Replacement laptop WiFi adapter
Changing the Wi-Fi module on a laptop is not difficult, especially there are models that have a cover on the bottom. When you open it you will see this module. You can buy another adapter that will connect via USB. Often, these adapters have an external antenna that amplifies wifi on laptops, which you can replace with a more powerful one in the future.
The question of how to strengthen the signal of a Wi-Fi router is asked today by many users.
First of all, this is due to the low quality of equipment distributed free of charge by providers, subject to ordering a certain package of services from them.
Such routers provide acceptable signal quality only in the line of sight at a relatively short distance.
It should be noted that in most cases this is quite enough, especially if distribution is planned in a wooden or brick house.
In addition to purely technical problems with the distribution radius of a Wi-Fi router, there is also a legislative limit on the maximum radiation power of such devices.
Ways to increase the coverage radius of a WI-FI network
- Installing a second router for distribution in an area not covered by the main emitter. Often this option allows you to solve the problem with minimal cost. The figure explains the principle of distribution using a repeater:
- You can purchase a high-quality router, for which three or four floors in a panel house are a normal service area. This is the most reliable, but also the most expensive option;
- You can significantly increase the service area by replacing the standard antenna of the router with a more powerful one. As a rule, large antennas have higher gain;
- Good results can be achieved by installing a simple signal reflector near the antenna (the design of one of the options is discussed below);
- If it is not possible to amplify the signal of the router, then you can try to find a place in the apartment from where the distribution will be carried out with minimal losses. This is a simple but very effective method.
Practical options for amplifying the signal of a wifi router
The old truth that the antenna is the best high-frequency amplifier has not been canceled.
Here is an example of a simple but very effective Wi-Fi band antenna providing 2x to 4x signal amplification:
If the manufacture of this antenna is difficult or there are no necessary skills, then a reflective screen can be installed near the standard antenna:
Despite the elementary nature of the design, the effect of its use is simply amazing, it is not in vain that they say that simple solutions are the most efficient.
In fact, the installation of the screen does not affect the radiation power of the WI-FI router.
But by directing all the energy into a limited space for the user, this is tantamount to doubling the radiated power.
A similar effect is achieved in a flashlight or table lamp due to a reflector that directs light in a given direction.
Good advice: remember the cost of your device / devices for which you are going to distribute Wi-Fi in the apartment, and think about whether it is worth saving on a good router.
Hidden reserves of equipment
Many users are in a hurry to connect a brand new Wi-Fi router and do not pay enough attention to studying the instruction manual.
As a rule, at the factory, the router parameters are set to medium or minimum values.
This is quite justified from the point of view of noise immunity, especially in a residential apartment building or office center oversaturated with similar devices.
Carefully inspect the router and study the instructions, because it is quite possible that to increase the power, it is enough to select the value of the software switch or rearrange the chip on the case.
It is possible to specify the installed power as a percentage or fixed: maximum/medium/low (High/Medium/Low).
The propagation of a microwave signal significantly depends not only on the location of the router relative to the walls of the room, but also on the position of its antenna.
It is worth experimenting with different placement of equipment in the room, as well as changing the angle of the antenna of the router or the device using Wi-Fi several times.
For the normal use of the WI-FI network, the parameters of not only the router are important, but also the equipment receiving the signal.
When working with a laptop, we must not forget that in order to save battery power, voltage limitation on the network module is practiced, which significantly reduces the range.
Be sure to check the power settings for a weak signal and adjust them if necessary.
