What does router mean? Router and router are the same thing. ADSL modem routers

Our company offers the service connecting the router, as well as diagnostics, repair, configuration and connection of a router (router) of a wired and wireless home computer network. The work is carried out on-site to the customer.

First of all, router in translation means router. This is the same device, sometimes called this, and sometimes that.
transfer data between different devices connected to one network, create routes and the order of this transfer and carry out their simultaneous operation in the global network. IN home network necessary connect router
to connect computers, laptops, smartphones, TVs and other devices to the communication channel of the Internet provider.

and its connection to a printer or disk storage. Using this port, there is no need to constantly keep the desktop on to print any documents or save data. The entire procedure is controlled by the connected router. From any device connected to your home network, you can save data to paper or electronic media. Reception and transmission of data from the global network can be carried out in several ways: via mobile communications, via telephone wire, via twisted pair cable, via antenna cable, via an electrical network, via a communications satellite. Accordingly, various devices are produced and it is necessary to understand how to connect a router

for a specific type of use of the global network. Mobile networks 3G and 4G - LTE, standard for data transmission technology through operators. 3G Internet is present almost throughout the Moscow region. 4G high-speed Internet All of Moscow and the immediate Moscow region are covered. In the router mobile network There is a built-in antenna for receiving signals from a cellular operator; in areas of poor reception, it is possible to use a special 3G antenna for the router, aimed at a cell tower. This significantly improves the quality of the Internet connection. A special socket on the case allows you to connect the router via an RF cable to the antenna.

Via wired telephone lines using the ADSL technology standard. This technology allows you to connect the router to the Internet through a regular telephone jack. There are varieties of ADSL2 and ADSL2+ technology that significantly increase data transfer speeds. The router is connected through a special splitter that separates audio transmission channels from information transmission channels. Each telephone connected in parallel is connected to telephone socket through a special ADSL microfilter, which ensures the preservation of the quality of telephone communication when transmitting information data packets.

Using a cable specially installed in the apartment twisted pair ETHERNET technology, which is installed in the apartment and allows you to connect the router to the provider’s equipment. This cable consists of 4 pairs of copper wires in common insulation, equally twisted together. This design has good noise immunity and allows data transmission at speeds of up to 100 Mbit/s. As a rule, it is these cables that connect various home network devices when connected to a router’s LAN socket by wire.

Via television antenna cable - EoC technology. In this case, the antenna cable already laid throughout the apartment is used to watch television programs. Through the splitter, the television signal and digital data are separated, the image and sound signals are supplied to the antenna input of the TV, and information signal via a coaxial cable must be connected to the router, to a specially designed input for this purpose. The convenience of this technology is that there is no need to install a special wire, since a television antenna is present in almost every home.

Via fiber optic cable - GPON technology. A special fiber optic cable is brought into the apartment, and by connecting a router, it connects various devices to the home network at speeds of up to 1 Gbit/sec. Actually, the abbreviation GPON is translated like this: gigabit passive optical network. Through this router connection, you can easily connect all home devices to the Internet and ensure high-quality channel reception digital television.

Via an electrical outlet - PLC technology. In this case, the role of a home computer network is played by the electrical wiring in the house. Use the instructions included with the adapter to find out how to connect the router. Data is transmitted through 220V electrical sockets and wires located in the apartment using special adapters.

Using a satellite antenna - two-way, when both the reception and transmission of information occurs through a communication satellite, or one-way (asymmetric) - when a satellite channel is used for data reception, and available terrestrial channels, usually mobile communication networks, are used for transmission.

According to the method of data transmission within the home network, that is, according to the method of connecting various devices and connecting them to the router, routers are divided into: wired - all devices on the network are connected only by special cables connected in LAN connector router, wireless - when all devices connect to each other and to the router via Wi-Fi wireless technology, and mixed, when the router has at least one LAN output and the ability wireless Wi-Fi connections.

The spread of the Internet encourages ordinary users to actively participate in the use of latest technologies without the help of specialist intermediaries. As practice has shown, it is not easy to find a true specialist in the field of IT technologies, and their services are not cheap. Another thing is the abundance of amateur consultants. And although they maintain prices for their services at a high level, the quality and volume of work they carry out is quite within the capabilities of an ordinary user.

Problems of organizing a local network arise not only for system administrators of enterprises and offices. Abundance digital devices, used by an ordinary average family, involuntarily requires not only the division of traffic, but also their inclusion in the general network. The most the best option The solution to this problem is to use a router (router).

What is a router? In the words of a specialist, this is a device that works as the main link of a local network. A router is a high-tech switch that, based on information about the network topology and certain rules, makes decisions about forwarding packets between the elements that make up the network.

The operating principle of the router is based on the use of the recipient address contained directly in the data packet, which is determined by the device and selects the data transmission path. If there is no route to describe the address, the packet is discarded.

Other methods for determining packet forwarding routes can use the source address; for this, upper-level protocols and other information contained in packet headers of a specific network layer are taken into account. Often, routers take on the function of translating the addresses of both the recipient and the sender of transit data, based on certain rules to limit access.

For regular user The question of what a router is has a much simpler answer. In fact, this is a compact device located at the input of the local network. Depending on its type, it can transmit data both via wires and via wireless communication technologies.

Dynamic routing allows the router to network a large number of elements and even several local contours. What is a router in in this case? This is a device that goes beyond the usual connecting link. It not only makes your work easier system administrator, but also provides the opportunity to organize a full-fledged local network by an ordinary user.

We no longer have to bother with specific concepts and jargon of specialists; there is no need to delve into the classification of protocols. It is enough to go through all the requirements of the instructions point by point, and as a result of a few minutes of work, the local network with wide possibilities at our service.

The process of setting up a router is so simple that even a schoolchild can handle it. Some inconsistencies may occur when determining the network address of the router itself, but they are resolved either automatically or manually (depending on the type of devices used).

If initially the definition of a router looked very confusing due to the use of specific terms, now anyone who has encountered its configuration and installation can answer the question of what a router is. A simple and affordable device that facilitates the process of organizing a network finds a place in the office and at home. The interface for working with it is simple and intuitive. The merit of the developers of modern routers is to simplify the process of setting them up, which makes them very common and accessible among a wide category of modern users.

Gone are the days when there was only one personal computer in the house. The average family, in addition to a PC/laptop, has a couple of smartphones, a tablet, and a smart TV. How to connect all this equipment to the Internet if the Internet provider cable can only be designed for one device? A specialized computer - a wireless router - comes to the rescue.

What is a Wi-Fi router and what is it for?

Any home user sooner or later he comes to the idea of ​​​​combining all his devices into a local network. This will allow you to organize network storage for music and movies, provide shared access to a printer or scanner, and even build a home video surveillance system. Although the main task will remain to ensure shared access of devices to the provider’s Internet channel.

Sooner or later, every user comes to the idea of ​​​​combining all their devices into a local network

To create a home local network and provide shared access to the Internet, the industry has long been producing specialized single board computers- routers or routers. They are able to receive data from the Internet provider and distribute traffic across all available devices. Routers equipped with ports for connecting wired clients and a wireless module Wi-Fi connection, will easily connect all your gadgets into a single network, and after the initial setup they will be able to work for months without turning off.

How a wireless router works

The principle of operation of a wireless router is to receive traffic from an Internet provider and distribute it to home network clients. The router software distributes traffic evenly to avoid speed dips for each connected user. Using the settings, you can limit the access of any connected client to certain Internet resources (black list) or allow access to the network strictly certain time(relevant for child users). All router settings are made through a graphical add-on to the software - the web interface. It opens in any internet browser like a regular website.

Appearance of the router, purpose of connectors and ports

A router is an autonomous device in a closed case with external or internal (hidden in the case) antennas. Most of the service connectors are located on the back panel of the router:

Also on the rear panel there may be power buttons and factory reset buttons. The button for creating a secure wireless connection is usually located on the front or side panel of the case and is equipped with LED indicator activity.

For clarity and ease of operation, the WPS button can be located on the side or front panel of the router

Types of routers

Currently, an Internet provider can provide an incoming channel using a wide variety of equipment. This could be traditional twisted pair UTP-8, copper telephone line noodles, coaxial television cable, or modern fiber optics. There may not be a cable at all if your provider is a mobile operator. Depending on type incoming channel are used different kinds routers.

ADSL modem routers

Among cable networks, telephone networks confidently lead in popularity, because There are wired telephones in the most remote and remote corners of the country. It would be unwise for Internet providers to ignore such an extensive cable structure. As a result of this, the world was born ADSL technology, allowing transmission at high speed over a pair of copper wires not only sound signal telephone line, but also data. The data channel is asynchronous - the reception speed (about 20–30 Mbit/s) is almost an order of magnitude higher than the transmission speed (about 3–5 Mbit/s).

DLINK DSL-2650 shows speeds of up to 30 Mbit/s over a telephone line, has two USB ports and excellent Internet sharing via Wi-Fi

Routers designed to work with such lines have a built-in ADSL modem and a corresponding port for connecting a telephone line. These can be either very simple and cheap devices that are not equipped with a wireless communication module, or mid-range 2-antenna devices that allow you to connect to a wireless network at speeds of up to 300 Mbit/s. ADSL routers are not represented in the premium segment, since the communication channel itself is very average in terms of speed characteristics, and a high-performance router will work “idle”.

Routers with twisted pair connections (Ethernet)

The largest family of routers are routers operating with a twisted pair connection (Ethernet). The ability to transmit data at speeds of up to 1 Gbit/s, the low cost of cable and the ease of installation make twisted pair networks the most common. Therefore, you can choose a router for such a connection to suit every taste and budget.

The most inexpensive models are equipped with one non-removable antenna and provide wireless network speeds of up to 150 Mbit/s, allowing you to connect up to 10 clients (in theory) and 2-4 computers over the air using twisted pair cables at speeds of up to 100 Mbit/s.

TP-LINK TL-WR740ND is equipped with one non-removable antenna and provides wireless network speeds of up to 150 Mbps

Advanced routers are equipped with three or four high-gain antennas, and support for 802.11 b/g/n and ac data transfer protocols allows you to achieve maximum wireless transmission data up to 900 Mbit/s. The ports for connecting using twisted pair cables on such devices are gigabit, both for connecting clients and for connecting to the provider. An integral attribute of such routers are one or more USB 2.0 ports for external hard drives, 3G modems and other peripherals.

TP-LINK TL-WR1043ND is a powerful three-antenna router with speeds up to 450 Mbps

3G/4G routers

In places where there are no Internet providers providing cable services, the only way to connect to the network is mobile Internet from one of the cellular operators - MTS, Beeline or Megafon. To work with 3G Internet, manufacturers produce specialized routers into which you can install a SIM card and distribute the Internet via Wi-Fi to several clients. Since such routers are often used on business trips or far from civilization, most of them have autonomous power supply from built-in battery, allowing you to work for several hours without recharging.

The 3G router fits easily into a trouser pocket and can run for several hours on the built-in battery.

Connecting to 3G Internet can also be done using a combination of a 3G modem and a wireless router with USB port. This hardware solution will allow you to combine the performance of a stationary router and the benefits mobile internet and is perfect for a summer residence, country house or field camp.

Routers with GPON interface

Despite the fact that most “last mile” cable routes (the wiring from the client to the Internet provider switch) are implemented using 8-core twisted pair Ethernet, more and more new routes are being laid by providers using fiber optic cables. Optics are cheaper, practically unaffected by moisture and corrosion, and most importantly, insensitive to electrical interference.

It’s no secret that during a thunderstorm, electrical noise in the cable network can damage not only the provider’s equipment, but also computers in the whole house.

Fiber optic cable is resistant to electrical interference, is not subject to corrosion and has enormous bandwidth To connect to a fiber optic Internet channel, you can use it as a media converter to which you connect regular router

, and a router equipped with a GPON port - an interface for connecting optics. Setting up such a router is no different from setting up a classic router with a twisted pair connection. The whole difference lies in the physical interface of the incoming channel.

Video: what types of routers exist

How to choose the right router for home, office or travel Before buying a router, you should outline the scope of its use. This will avoid extra costs

and situations where the device cannot solve problems due to its low performance.

Router for home When choosing a router for an apartment in a multi-storey building, it is worth considering several points. IN many other routers work, because the neighbors also have Internet. To minimize the impact of other devices on your router's signal, you should give preference to a device with internal antennas of sufficient power.

They will provide coverage inside the apartment without receiving signals from other people's routers. The ideal option would be to purchase a 5 GHz router. This signal fades faster, and the standard provides more free channels than the 2.4 GHz standard. The absence of external antennas will make the router less vulnerable when interacting with children and pets.

The 720th TP-LINK has a small size and good characteristics

Router for office For a router used in an office, performance and power are paramount wireless interface

. It would also be useful to have USB ports to provide shared access to the printer. To ensure a stable wireless connection and the speed does not drop, choose tri-band models equipped with high-gain antennas. The ASUS RT-N66U router will provide stable wireless communication

anywhere in your office

Travel Router For field work and business trips, you will need a 3G router with the ability to operate autonomously from the built-in battery. The router model is secondary here, because the speed of the mobile communication channel can “digest” any mobile router

, released in 2017–2018. In order not to overpay, it makes sense to take the router for which the mobile operator will have the maximum discount when concluding a contract. Sign a contract with Beeline (or other mobile operator

) and receive a 4G router as a gift

5 GHz routers and their advantages over 2.4 GHz routers

Squeezing 300 Mbps out of a 2.4 GHz router if it is operated in an apartment building or office building with a large amount of wireless equipment is an almost impossible task. Routers interfere with each other's work, the data transfer speed drops by 2 and 4 times (from the theoretically possible). The electronics industry has proposed a solution in the form of a new data transfer standard, 802.11 AC. Equipment of this standard operates at a higher (twice) frequency - 5 GHz. This provides large quantity

Increasing the broadcast frequency causes the signal to attenuate faster and pass through walls less well. Such a signal spreads freely throughout the area of ​​your apartment/office, but does not reach your neighbor’s “possessions”.

Before buying an 802.11 AC router, be sure to make sure that all your other equipment (smartphones, tablets, laptop) can also work in this frequency range. Otherwise, the router will operate in compatibility mode at the 2.4 GHz frequency and all its advantages will remain only on the paper of the advertising brochure.

Popular Wi-Fi router manufacturers and reviews

The three largest manufacturers of home routers include Asus, Zyxel, TP-Link. Each manufacturer has devices to suit every taste and budget, and even junior models will be equipped with branded features that make the brand recognizable.

Zyxel

The company has been producing communications and network equipment for decades. In the 90s, Zyxel was famous for its excellent characteristics and uncompromising quality of telephone lines. On this moment the company is not giving up its positions.

The company's product range includes ADSL routers, repeaters, access points, managed switches. But the subject of special pride is wireless routers Keenetic series.

For inexperienced users Routers are produced with low requirements Keenetic Start- single-band routers with a maximum wireless network speed of 150 Mbit/s. The number of wired ports is 4 or 2 (depending on the generation of the router). The use of a processor with low speed characteristics has a pleasant side effect - the router practically does not heat up during operation, so it can be safely used in hot summers or in rooms with difficult climatic conditions.

Keenetic Start is an entry-level router, but has a number of advantages that older models cannot boast of

Buyers who want to provide Internet access to a small office or a multi-level private home, it makes sense to choose the model Zyxel Keenetic II. External antennas with a gain of 5 dB, a wireless network speed of up to 300 Mbps, as well as two USB ports will provide users with high-speed Internet and allow them to share network storage, printers and scanners.

Keenetic II provides high-speed Internet and will allow you to share network storage, printers and scanners

The premium segment is presented powerful router Keenetic Giga. The dual-band, four-antenna router is capable of reaching wireless network speeds of up to 900 Mbps and connecting computers over twisted pair cables at 1 Gbps. High-performance dual-core processor and 128 megabytes random access memory allow you to simultaneously serve a large number of connected users without reducing speed.

Keenetic Giga allows you to simultaneously serve a large number of connected users without reducing speed

Wi-Fi router Zyxel Keenetic - great idea and software, but crappy hardware. ADVANTAGES: programmers and firmware, website and technical support, unparalleled capabilities of the Kinetic series router. DISADVANTAGES: IRON. Where do you buy such filthy microcircuits? A little over a week later, the Wi-Fi module died (my netbook can see the ZyXEL access point, but cannot get an IP address from Kinetic). Everything is fine with the other router, the netbook is 100% working. Resetting, flashing and all sorts of Wi-Fi settings did not help. True, the rest of the router (via twisted pair cable) works like a charm, but I still took it and returned the device for warranty (despite the fact that another 2 weeks had not passed, Svyaznoy refused to return the money). I think it's just an annoying hardware defect. Everything is good with ZyXEL: programmers and firmware, website and technical support, unparalleled capabilities of the Kinetic series router... BUT HARDWARE. Where do you buy such filthy microcircuits? Sad to the end! Now we have to wait a month or so for a replacement...

Wi-Fi router Zyxel Keenetic Giga III is a productive router with support for IEEE 802.11ac. ADVANTAGES: productive, reliable, simple and convenient settings, wide functionality, powerful signal. DISADVANTAGES: prohibitive price. The Zyxel Keenetic Giga III router has a lot functionality. And what’s even better is that you don’t have to load your device with unused tools. The firmware is modular, that is, after enabling the required feature, its support is loaded and control settings appear. Comfortable. All three buttons can be programmed at your discretion. More than covers all my needs (dual band, port forwarding, DMZ, strong signal, MAC address filtering, FTP, DLNA, USB3 for external HDD). About the bad - the price is steep, but I got it practically for free (I accumulated bonuses from a network retailer).

ASUS

ASUS Corporation produces a wide range of electronic and computer equipment. And although routers are not at the top of this list, the line of routers includes worthy models that are not inferior and even in some ways superior to competitors’ products. True, this applies to most premium segment models.

The budget segment is presented ASUS models RT-N10 and ASUS RT-N10LX. By today's standards, these are extremely low-performance devices with little RAM and a slow processor. Their older brother ASUS RT-N12 differs only in the presence of a second antenna, providing wireless network speeds of up to 300 Mbps. Routers are very “hot”; their operation in the hot summer without additional cooling is fraught with interruptions in operation, and even failure of devices.

ASUS RT-N12 features a second antenna that provides wireless network speeds of up to 300 Mbps

A classic representative of the middle segment is the ASUS RT-N14U router. A router with an attractive design. It will fit perfectly into both the interior of an apartment and an office. Two internal antennas allow you to reach wireless network speeds of up to 300 Mbps, and a USB 2.0 port allows you to connect external hard disks, printers and 3G modems. The AsusWRT firmware is unified with the older line of routers and allows you to flexibly configure the router to suit your needs. Disadvantages include increased power consumption (a 12 V power supply with a current of 1.5 A is used) and high heat generation. When installing the router, find a place for it away from direct sunlight and with air flow, otherwise interruptions in operation may occur.

ASUS RT-N14U has nice design and good characteristics

Premium ASUS devices are at the peak of progress: large volume RAM, 4 antennas for two bands and an active cooling system allow such routers to operate 24 hours a day for months, providing the Internet and local network to a medium-sized office. Such devices would also be useful at home for avid gamers, web developers, coders and all those who need a fast and stable Internet channel. Users who want to purchase a top-end router and save money should take a closer look at the ASUS RT-N66U. Despite its venerable age by modern standards, this three-antenna dual-band unit can still satisfy 99% of the needs of a sophisticated Internet user.

https://otzovik.com/review_1985797.html

WiFi Asus router RT-N66U is a high-speed router for a home network. ADVANTAGES: brand, quality, power, signal strength, good software, a lot additional features. DISADVANTAGES: price, heating of the case. This is the second router that appeared at my home to replace the broken one, also from Asus. The fact is that the first one had a rather low data transfer speed, and my husband and I decided that there was no point in repairing it, it was better to take a high-speed one. So, based on reviews, we settled on the Asus RT-N66U router. The Internet really was flying, for almost six months. And the router is quite sophisticated in many respects. How one fine day the Internet began to fail. I started looking for the reason in the provider, they like to turn off our Internet. But this time the reason turned out to be in the router. We tested the router from both sides together with the network configurer and it turned out that the Internet was slowing down the router. He turned it on for two seconds and cut it off. Fortunately, we had a guarantee, we took the router to be repaired. I don’t know what happened to it, but they returned me a completely new, sealed router, which I’m glad about. It's better than having it repaired. I hope that the new Asus RT-N66U router will last me more than six months :)

TP-LINK

TP-LINK company entering the market of countries former CIS, set itself the task of offering customers routers at a price lower than competitors, but with similar technical characteristics. This was partially successful, especially in the budget segment, where the user counts every ruble. In the mid-price niche, the gap is no longer so obvious, and some functions are added rather for show. As an example, we can cite the TL-WR842N router. It is equipped with a USB port, but the standard software allows you to connect only a printer to it. However, TP-LINK routers are reliable and unpretentious. It’s no wonder that Internet providers buy thousands of them for installation to their clients.

The budget segment is represented by a “classic of the genre” - the TP-LINK TL-WR741N router. This is a simple single-band device equipped with a 150 Mbps wireless module and four twisted pair ports. The amount of memory and processor speed allow you to distribute the Internet to 4–5 clients without reducing speed, so this router they buy not only for home, but also for small offices. For users who will not connect more than two devices to the router (computer + smartphone), a simplified version of the router has been released - TL-WR720. It has only two wired ports, and the antenna is internal.

TL-WR741N is bought not only for homes, but also for small offices

The middle price category includes routers of the eighth and ninth series (841N, 842N, 941N, 942N). All devices are dual-band. The eighth series is equipped with two antennas (access speed up to 300 Mbit/s), and the ninth - three (its speed is one and a half times higher). The best model in the segment is the TL-WR942N router. The increased amount of RAM and expanded software allow you to flexibly use the built-in USB port both for network storage and for creating a backup Internet channel in conjunction with a 3G modem.

TL-WR942N is a balanced solution for home and small office

The line of premium routers is represented by TP-LINK Archer. The routers will provide you with high-speed Internet (1 Gbit/s) and allow you to work with wireless networks in the 2.4 and 5 GHz range, and also create a backup channel using a 3G modem. Depending on the model, routers can be equipped with three, four or even six highly efficient antennas, which will allow the wireless network to operate stably even in the littered air of an office center or apartment building. And the use of energy-efficient processors from Mediatek as the “heart” of the router allows the router to remain cool even in hot summers, operating steadily and without failures.

Archer C3200 is a collection of advanced technical solutions and futuristic appearance

Wi-Fi router TP-Link Archer C1200 - reliable access on the Internet and more. ADVANTAGES: reliable operation, multifunctionality, upgradability, price. DISADVANTAGES: minor when operating at 5 GHz. A router is a very important home device; Internet access, which is necessary for all home devices, depends on its performance. If the router does not work or malfunctions, then every member of your family will notice. Therefore, choosing a router should be approached as carefully and carefully as possible. The device must be reliable, functional and, if possible, inexpensive. Many of the features of professional home routers are unnecessary and have a negative impact on the price. We have been adherents of D-Link technology for many years, but despite its high functionality and its inherent bells and whistles, it is very sensitive to comfortable working conditions. Previous D-Link router In winter, when the central heating was on, it very often went into reboot, so it was decided, along with replacing the desktop computer, to also change the router. And this time they chose another one TP-Link, and for more than two months daily work he performed excellently. I have never restarted, even after replacing the computer with a more powerful one, which also heats up more intensely. The TP-Link Archer C1200 router itself also has a non-critical warm case temperature, not causing problems with performance in the sense of freezes and unauthorized reboots. What was particularly missing from the previous D-Link router were power on and off buttons. When it froze, I had to pull out the power connector, but this is wrong. There is a special convenient button, but restarts are not needed on this reliable equipment. And if you are going to do this for some reason, then on a normally working device it is better to do it through a program. The router provides good support DDNS. When changing a dynamic IP address, it is always possible to contact and find your personal computer or any other device on your home network on the vast expanses of the Internet using a standard Internet link. I often use this to transfer photos from my smartphone to my Intel NUC BOXNUC 7i7BNH. TP-Link Archer provides parental controls. It allows you to restrict Internet access to any device on your home network by a specified time and day of the week. For example, you don’t want your child to play on the Internet in your absence instead of doing homework on weekdays when you’re away; to do this, set the restriction parameters and sit quietly at work. You can connect a wireless modem in case it suddenly disconnects wired Internet or it doesn’t exist at all. But the manufacturer does not guarantee stable operation with all wireless modems. If you obviously need a wireless Internet connection, then it is better to immediately take another device that is 100% suitable for this type of connection, containing a built-in modem that only needs to insert a SIM card. A flash card inserted into the TP-Link C1200 router becomes available for viewing from any home device and serves as a so-called media center. But we don’t really need this, because our network has a more advanced device, namely the D-Link network storage with greater capabilities and volumes of stored information. You can connect a printer to the router, which makes it possible to print from any home device, but here you need to separately check the compatibility of devices in the list on the manufacturer’s website. Supports two bands at once WI-FI networks 2.4 GHz and 5 GHz. Of these, more new network 5 GHz and it is good because its channel is not occupied due to the fact that it has not come into widespread use; few people still use it. However, it is sensitive to obstacles - this is both a plus and a minus at the same time.

Review: Wi-Fi router TP-Link TL-WR720N - lightweight router - easy internet. ADVANTAGES: price, weight, simplicity. DISADVANTAGES: short LAN cable. If you don’t want problems with the Internet, buy a router. Now there are so many different models to suit every taste and budget. I chose the cheapest one, I confess. Besides, additional advantage What struck me was the lack of antenna horns on this model. The internal antenna does the job quite well. The box with the router contains almost all the information about the product. By turning it in all directions, you will learn everything about the model. In addition, there is a guide for quickly connecting the router and an installation disk with a Quick Setup Wizard. The Russian language is presented in the manual (as well as on the disk). Quick connection- not a common word in the manual. The whole process took me literally a couple of minutes. The step-by-step instructions do not allow you to turn anywhere. Here it is, my router, working at full speed, cheerfully winking with LEDs and shoveling megabits and gigabits of information. Rear connection ports: one WAN port, two LAN ports. Some may think that this is not enough. I have enough for one laptop (there are no two here at the same time). And the tablet uses Wi-Fi. There is also a power socket and a reset button, surprisingly, not recessed, but tight. You won't reset it by accident. The lower part contains only information about the model and loops for mounting the router on the wall. But they haven’t gotten around to it yet. Let's summarize. An absolutely gorgeous router model for such a price, even though it was made in the Middle Kingdom. Fast, easy and convenient. The only negative is the short LAN cable, but this can easily be fixed by switching the laptop to Wi-Fi.

Connecting and setting up a Wi-Fi router

Thanks to the user-friendly software of most routers, setting them up is simple and accessible even to an untrained user. Let's look at connecting a router using the example of TP-LINK devices:

1. Configure your computer's network card to automatic receipt network address and DNS addresses. The easiest way to do this is by entering the command “netsh interface ip set address” in the “Command Line” Local Area Connection"dhcp".
2. Connect the provider cable to the socket marked WAN or Internet, and connect the laptop or computer using a patch cable to any free socket marked LAN.

   For initial setup, the provider cable must be inserted into the socket marked WAN or Internet, and the PC/laptop must be connected to the socket marked LAN

3. By entering 192.168.1.1 in the address bar of your browser, open the router’s web interface. From the list of sections on the left side of the window, select “Quick Setup”. On the first screen, simply click the "Next" button.

   The Quick Setup Wizard will the best option connections for an inexperienced user

4. On the next screen, select your country, city, ISP name, and WAN connection type from the drop-down lists. If your provider is not in the list, check the “I did not find suitable settings” checkbox and click the “Next” button.

   The type of connection to the provider can be selected from the list

5. Enter the username and password from the agreement with the Internet provider. If your tariff plan includes a digital television service, additionally select the type of secondary connection: static address or dynamic. Click "Next".

   The login and password for accessing the Internet can be found in the agreement with your provider

6. If your ISP provides a MAC-based connection network card, clone the address of the computer’s network card into the WAN interface of the router.

   Be sure to clone the MAC address if your provider requires it

7. For routers equipped with a USB port, you can select a 3G modem as a backup channel. The router will switch to it if the main WAN interface is unavailable. Select your mobile service provider and fill in all fields in the dialog box.

   Mark the ranges in which the router will be allowed to operate

8. Enter the name of the wireless network and its password, then click the “Next” button. If the router is dual-band, a similar settings window will open for the 5 GHz band.
9. Within two to three minutes, the router will apply the settings, connect to the provider’s channel and be ready for use.

The correct formulation of the question contains 90% of the answer. Having found out in advance the requirements of the Internet provider for client equipment, having decided where the router will work and what devices will connect to it, you can choose a router with balanced characteristics without spending a lot of money and ensuring your home network with stable and uninterrupted operation.

, /ˈɹaʊtɚ/) or router(reading the word in English. router as transliterated)) is a specialized network computer that has at least two network interfaces and forwards data packets between different network segments, making forwarding decisions based on information about the network topology and certain rules specified by the administrator.

Routers are divided into software and hardware. A router operates at a higher "network" layer 3 of the OSI network model than a switch and network bridge, which operate at layer 2 and layer 1 of the OSI model, respectively.

Principle of operation

Typically, a router uses the destination address specified in the packet data and determines from the routing table the path along which the data should be sent. If there is no described route in the routing table for an address, the packet is discarded.

There are other ways to determine the forwarding route of packets, such as using the source address, the upper layer protocols used, and other information contained in the network layer packet headers. Often, routers can translate the addresses of the sender and recipient, filter the transit data stream based on certain rules to limit access, encrypt/decrypt the transmitted data, etc.

Routing table

Application

Routers help reduce network congestion by dividing it into collision domains or broadcast domains, as well as by filtering packets. They are mainly used to combine networks of different types, often incompatible in architecture and protocols, for example, to combine Ethernet local networks and WAN connections using xDSL, PPP, ATM, Frame relay, etc. protocols. A router is often used to provide access from local network to the global Internet, performing the functions of address translation and firewall.

A router can be either a specialized (hardware) device or a regular computer that performs the functions of a router. There are several packages software(based on Linux kernel, based on BSD operating systems) with which you can turn your PC into a high-performance and feature-rich router, such as Quagga, IPFW or an easy-to-use router.

Data collection and transmission devices (DCD) in AIIS KUE

The router is the main network device of the AIIS KUE network. The main function of the router is the transit of digital information flows between executive devices (for example, meters) in the energy consumption network and the center. It is intended for configuring communication channels, agreeing on protocols and ensuring the exchange of data from energy meters, concentrators, repeaters and other components of automated information-measuring systems for commercial and technical accounting of energy resources. A distinctive feature is the ability to use several data transmission channels simultaneously (GSM / GPRS, PLC, Radio channel, Ethernet, RS-232, etc.)
