In many residential buildings and commercial organizations, the wireless method of data transmission via Wi-Fi networks is widely used. However, we periodically have to face situations in which the signal weakens, disappears, and the quality of communication deteriorates. Such cases occur for many reasons, among them: the limited range of the router, load-bearing walls, reinforced concrete, glass structures, etc. Such an autonomous device as a repeater is an effective and affordable means of solving this problem.
The algorithm of its work consists in the fact that the device first captures the main access point, duplicates it and then transmits it to a further distance, you can read more about the process at https://mobilebooster.ru/post/154/usiliteli-signala-sotovoy-svyazi-raznovidnosti-opisanie-rekomendatsii/. At the same time, a working local network, i.e. IP addresses and other parameters do not change. It should be understood that the repeater does not amplify the power of the existing signal, does not increase the speed of Internet work. It is designed exclusively for the expansion of the coverage area.
Externally, it resembles a regular router with one or two antennas, Ethernet and USB switches for connecting individual data carriers. It can also be in the form of a compact power supply unit with an electric plug, LED indicators, and control buttons.
Recommendations for selection
For a two-story house, cottage, office, a device with several external transceivers is suitable, in small apartments, an option with built-in dipoles is appropriate.
Before buying, the following criteria are taken into account:
• technical characteristics;
• area, layout and type of premises;
• number of users and end devices;
• manufacturers.
The equipment can work in two bands - 2,4 and 5 GHz. Most routers operate at the 2400 MHz frequency, so it is crowded, and interference often occurs. The frequency of 5000 MHz is more free, has many channels, a good high-speed result, but a smaller working area. The scheme is considered rational when the repeater is synchronized with the Wi-Fi router, and they are manufactured by the same company.
Models from the companies TP-link (RE350, TL-WA850RE, RE200), Xiaomi, D-link are now popular.
Standard routers can work as repeaters. This function is supported by Asus and ZyXel products.
Setting
First, it is necessary to choose the most suitable location, where there is still stable but weakening signal reception, in direct line of sight from the WiFi router, near the outlet.
Connection is carried out in two ways:
• by pressing the WPS key, the amplifier automatically finds the desired network and broadcasts it;
• manually through the web interface, using a patch cord to connect to a PC or laptop.
At the final stage, we check the result. To do this, we measure the speed of the Internet connection using a special service.
