Initially, the existence of wi-fi was achieved by installing routers. Although with their help it is not always possible to achieve a positive result and create an excellent quality of wireless connection in the desired area. Here comes to the rescue powerful wifi A repeater capable of significantly improving the transmitted signal.
After setting wireless network in some parts of the apartment or office is observed weak signal the internet. In these cases it is necessary to acquire powerful wifi repeater. Often considered the device is considered a signal amplifier from the Internet, but in fact this compact device serves as an extension cord. In other words, a powerful wi-fi repeater repeats some of the impulses emitted by the router and sends them on.
There are two types of devices on the market for related electronic products. The first is called single-band because it only works with 2.4 GHz frequencies. Another powerful wi-fi repeater accepts frequencies of 5 GHz, being not only a repeater, but also unloads a busy communication channel in two directions.
Setup of any repeater is carried out in the usual manner. The device is connected to the mains, then connected to the router. This can be done via wi-fi, although it is better to use a wired connection. Because then a powerful wi-fi repeater will not be affected by wireless network problems.
Then, using the wizard quick setup, scan and select the desired network. Access password is also indicated.
Instrument testing
Powerful wi-fi repeater must cope with the task that is not under the power of the router. For example, to create a good wireless Internet connection where there are serious obstacles.
Some amplifying devices have special signal strength indicators. So, the blue color of the light bulb will indicate a fairly good reception. When the red indicator should move the repitor closer to the router.
Special program iPerf3
The special iPerf3 program will help determine the resulting maximum speed. local networknot dependent on the provider. Then use speedtest.net to find out pure traffic. The results obtained should indicate the smooth operation of the device.
The powerful wi-fi repeater is dual-band, since only then its high performance will be outlined.
At the same time, a small frequency characterizing the router will not be important. It is recommended to consider the size of a good repeater, which will affect the location of all devices.
Features of using the device
It is not always necessary to use a repeater to amplify the wi-fi signal. Sometimes it is enough to put a router in the center of a building so that the distance to potential consumers is approximately the same. After all, the most common mistake is to install a router where it is easiest to get a cable.
To block the router is also not worth the various bulk items. The directivity of the antennas of the router can significantly affect the reception of the signal, which will exclude the purchase of a repeater.
The program wi-fi Analyzer will help to best place the router.
Program wi-fi Analyzer
Reception of a signal from a wireless connection is weak due to channel congestion. This will help flashing the router or replacing it with an improved version.
The increasing distribution of wireless access to the network using WiFi technology, imposes the need to use additional hardware to enhance and expand the radio signal. Such a wireless network can easily connect from any laptop, smartphone, tablet or other mobile device. In order to extend the signal to a considerable distance from the access point, a wi fi signal amplifier is used. With it, you can expand the access area from one room where the access point is located, to the borders of the whole house and the adjacent area. This allows you to organize an extended access point. Many educational institutions, shopping centers, cafes, libraries and train stations are equipped with such free access points to the World Wide Web.

The main purpose and principle of operation of the wifi network amplifier
Repeater or wifi amplifier The signal is designed to amplify the signal transmitted by the router and expand its radius to an area of more than twenty meters. A repeater or repeater signal will significantly expand your home or corporate network, which can be accessed by a large number of users. The network amplifier is powered from an ordinary household outlet, with a nominal voltage of 220 V. Externally, it is a small device, in form and design similar to a charger for mobile phone. The amplifier is practical and easy to use. It should be installed at a distance of half the distance from the router to the fixed access point.
How to enhance the signal wi fi?
Installing and connecting the repeater to the computer and the outlet, you must make the appropriate software settings. Go to the "Control Panel" and select "Network and Internet." Next, select "Network Control Center and shared"And click on" Change adapter settings. " Now selecting the “local area connection” item, right-click on it and select context menu item "Properties". If you have already created a wireless home network, which was configured in the automatic mode, it is necessary to make changes to the settings by selecting "Repeater Settings". Having made all the appropriate settings and saving them, you should move to the browser. In order for the wifi amplifier to have its IP address, as well as to assign it a gateway, do the following. Type 192.168.10.1 in the address bar. Having come to this address, log in under a standard name and password: admin. If your home network is password protected, then you need to configure an encryption type similar to a router.
After all network settings and access settings are completed, you can disconnect the wifi signal amplifier from the computer. Now he is fully ready for work and will be able to provide access to the Internet for all users in the house and in the adjacent territory (only those who have a password to access the network). Using a wireless network amplifier, you can guarantee the presence of a signal anywhere in your home.
However, the practicality of this device for domestic purposes is questionable. More often, wireless amplifiers are found in public places. An access point that is equipped with such an amplifier must have good bandwidth, both for incoming and outgoing traffic, in order to provide all visitors with “fast” Internet. Thus, the interest of potential customers to this institution will increase significantly.
What is a Wi-Fi repeater and how to use it to enhance the signal of a wireless network?
The repeater is used to extend the coverage of Wi-Fi. It helps to improve the reception quality of the wireless network when the signal is unstable.
This is true for large premises, houses and apartments. Walls, partitions and furniture impair strength Wi-Fi signal. At the same time, the Wi-Fi may not catch at all or the Internet speed will drop sharply.
Wi-Fi repeater duplicates the signal coming from the router and distributes it. If you have an extra access point lying around or Wi-Fi router, they can also be used as a signal amplifier.
Another way is a wireless amplifier or a more powerful antenna. Looks modern Wi-Fi amplifier as a power supply plug into a power outlet.
It is best to use a regular router with multiple antennas. In this case, it turns out to achieve a significant signal amplification, expansion of the coverage area and improvement of reception quality.
At the best wi-Fi reception, increases and the speed of the Internet.
Gain with repeater
Of the most interesting ready-made solutions - Tp-link repeater TL-WA850RE (Wi-Fi Range Extender). This device can operate at speeds up to 300 megabits per second, has two built-in antennas and 1 rj-45 port (Ethernet) for connecting a network cable.
It is enough to plug it into any free outlet in the room or part of the room where the reception level is low. After that, you need to configure the device in one of several ways.
- automatic connection to the router via WPS
- via phone, tablet or laptop
- by network cableby connecting with a computer or laptop
Now there is no need to be a specialist in electronics in order to independently enhance the WiFi signal. You just need to buy a special device that allows you to improve the reception of a wireless signal, or such an amplifier can be assembled with your own hands, of course with the instruction. Below is detailed information about the types of such devices and specific recommendations for their selection.
Types
Devices to increase power wifi reception are divided into the following 2 types:
- Active type signal amplifiers - repeaters (repeaters);
- Passive type signal amplifiers - antennas of special design.
Active-type Wi-Fi amplifiers
There are several types of devices with an active principle of operation:
1. Repeaters
Specialists call them differently: “Access points”. These devices are widely represented by manufacturers and significantly differ in their power characteristics and their dimensions. They are also differently staffed and have the support of different types of standards. The following companies are leaders in this market:
- D-Link;
- ASUS;
- TP-Link.
They have, as well as budget types of equipment intended for individuals, as well as very powerful devices for large companies and firms.
2. Repeaters for personal use at home
The TP LINK TL WA850RE repeater was deservedly especially popular among individuals. The device has 1 specific purpose, which improves the user's reception of a wireless signal, which it successfully performs.
Another important advantage of this device is the absence of the need to configure it. It is only necessary to activate the WPS file in the Wi-Fi router, and on the repeater to press 1 key.
Devices of a similar type are now on the market a huge amount. They differ in the following characteristics:
Passive type signal amplifiers
Or they are called Wi-Fi antenna special design. They are equipped with the routers themselves or are connected directly to the receiver's Wi-Fi signal.
Passive amplifiers differ in the following parameters:
- On the main parameter, which is called "Gain". Basically, its value in devices varies in the range of 8–15 dB, which corresponds to a radius of about 0.5 km, provided that there are no obstacles in the path of the signal;
- By focus. If the antenna is of the omnidirectional type, it means that it operates at 360 C. In the case of the directional type, the signal is received or transmitted only to one specific side to which the device is directed.
- On the supported frequency. For example, 802.11AC (5 GHz) or 802.11N (2.4 GHz). It is imperative to purchase an antenna, the standard of which corresponds to the router or device to which it will be connected.
Homemade device
In the absence of the possibility of buying an amplifier, you can make it manually.
Required list of materials:
- Coaxial cable;
- Wire - preferably copper;
- A small plastic box, such as a food container;
- Foil (aluminum).
The assembly procedure will take approximately one quarter of an hour.
Algorithm of actions:
The developer of this device, Danilo Laritsza, claims that the antenna is effective within a radius of 0.4 kilometers.
