A router is a very complex device with many technical characteristics. We will focus on those that are playing important role for the buyer.

WAN port type and connection protocols

The WAN (or Internet) connector is used to connect an Internet cable to the router. This is the first detail you should pay attention to when purchasing a device. The compatibility of the selected model with the provider depends on it.

A typical router has a WAN port in one of two formats:

1. DSL(ADSL, VDSL and other subtypes) - for connecting to the Internet via a telephone line.
2. Ethernet- to connect through a special provider channel.

There are also universal routers, which support several formats, including DSL and Ethernet. But they are much less common.

First, find out what technical requirements your Internet service provider has for your router. Visit the provider's official website or call support.

In addition to the WAN port format, technical requirements may include connection protocols with which the router must be compatible.

If, instead of DSL and Ethernet, the provider uses specific connection technologies, which rarely happens, then it is better to trust the choice of equipment to specialists.

Number and type of LAN ports

Computers, consoles, TVs and other stationary equipment that require stable wired access to the Internet are connected to the router’s LAN ports. This connection always guarantees maximum speed, which does not depend on distance and interference.

And the more such connectors in the router, the more devices can be connected to it via wire. Routers are usually equipped with four LAN ports. But if this is not enough for you, choose a model with additional connectors.

The maximum speed of data exchange between the router and other devices connected to it via a wire depends on the type of LAN ports.

There are two such types:

1. Fast Ethernet provides speeds up to 100 Mbit/s.
2. Gigabit Ethernet- up to 1 Gbit/s.

If your provider offers Internet access at speeds greater than 100 Mbps, choose a router model with Gigabit Ethernet ports. This way you will use your channel to its fullest.

Wi-Fi standards

The maximum possible speed of data exchange between the router and the fleet of devices connected to it depends on the Wi-Fi standard demon wired way. Two standards are relevant:

1. 802.11n- a widespread version that is supported by the vast majority of gadgets. Possible speed is up to 600 Mbit/s.
2. 802.11ac- an increasingly popular standard that provides the most high speed- up to 6.77 Gbit/s.

But don’t let the characteristics confuse you: the indicated values ​​are only theoretically possible within the technology. Real indicators speeds are much lower.

The speed specified by the manufacturer is also most often unattainable in practice. This is only a possible value without taking into account distance and interference.

Thanks to backward compatibility You can connect any gadgets to a router with the 802.11ac standard via Wi-Fi. Even if they only support 802.11n and older versions. But to unlock the full potential of 802.11ac, both your router and all other devices on your wireless network must support this standard.

It’s not at all necessary to chase newness and buy a router that supports 802.11ac. If you use the Internet only for web surfing and office tasks, you can save money and get by with a model with the 802.11n standard.

Number of Wi-Fi bands

Some routers can work simultaneously in different frequency ranges. In this mode, the router is able to support not one, but several independent Wi-Fi networks.

Many popular models are able to distribute data transmission between two ranges. Thus, they create two networks at frequencies of 2.4 GHz and 5 GHz, respectively.

1. Frequency 2.4 GHz ideal for connecting smartphones and office equipment.
2. Frequency 5 GHz provides a more stable and faster connection, and therefore is better suited for multimedia devices that work with video and other heavy content. So, if you don’t want to connect a TV or set-top box via wires, you can use Wi-Fi at a frequency of 5 GHz.

These networks can operate in parallel without limiting each other. But again, their total speed will not exceed the limit set by the Internet provider.

In addition, not all gadgets support a 5 GHz network.

Number and type of antennas

In addition to standard and frequency Wi-Fi work, the speed of the wireless network depends on the number of antennas in the router. The more there are, the faster exchange data between connected devices and the router.

Limit Wi-Fi speed in the 802.11n standard for a model with one antenna is 150 Mbit/s. With two - 300 Mbit/s, with three - 450 Mbit/s. That is, with each antenna the maximum possible speed increases by 150 Mbit/s. And in the 802.11ac standard - at 433 Mbit/s.

Let us remember that we are talking about theoretically possible speeds at ideal conditions. In reality, these figures are much lower. In addition, do not forget that the final speed of Internet access via Wi-Fi cannot exceed the provider’s limit.

Antennas can be built-in or external. As practice shows, in a typical city apartment, the type of antennas is not so important. Contrary to popular myth, the difference is barely noticeable.

But for large rooms it is still worth choosing a router with external antennas so as not to have. Moreover, if external antennas removable, if necessary they can be replaced with more powerful ones.

Availability of USB port

By choosing a router with one or two USB connectors, you can connect to it additional devices. For example, a USB drive will provide remote access To shared storage files via any device in Wi-Fi networks. A wireless USB modem will be yours in a backup way access to the Internet, if cable internet will stop working.

Brief selection instructions

Let's go through it again key points articles. This checklist will help you choose a good router.

1. Find out the provider's requirements for the router: type of WAN connector and connection protocols. Only then choose a model.
2. If the Internet speed is above 100 Mbit/s, buy a device with Gigabit Ethernet LAN ports (1 Gbit/s). If the speed is lower, Fast Ethernet connectors (100 Mbit/s) will suffice.
3. If access to the Internet is needed only for browsing websites and working with documents, you can limit yourself to a router with one antenna and support wireless standard 802.11n.
4. But if you watch streaming videos, play online games, use a lot wireless devices, download often large files and are not used to denying yourself, then choose dual band router with multiple antennas and 802.11ac support.
5. If you wish, you can buy a model with a USB port to connect a storage device or wireless modem to it.

Modern world high technology quite complicated even for a person who regularly uses a computer and the Internet, sends emails, communicates and finds information on the Internet. In this article, we will look at what is the difference between a router and a router? After all, these devices are actively used to create wireless networks and Internet connections, and therefore they are found in almost every home, apartment or office.

In fact, router and router are the names of the same device. This is a kind of mini-computer that provides Internet access to several devices at once. Linguistics also confirms this - the word “router” itself is borrowed from English language(router) and is translated as a router. Therefore, it would be fair to consider these words synonyms.

A router is used to create and manage a local network. The device contains a special built-in software. It includes security elements and settings packages. The secondary functions of the router (router) are to restrict access to specific resources, protect against malware and many more etc.

From a design point of view and appearance the device is a small plastic block with an antenna (or antennas), a power cable and a patch cord (a special patch cord).

Why is there confusion?

Since a router is no different from a router, why do a significant number of people continue to think differently? There are several reasons for this.

Firstly, banal illiteracy in this matter. Users naively think that “router” and “router” mean various devices, because they are called differently. At the same time it gets ridiculous. Some “experts,” for example, say that a router has a lot of advantages over a router, noting the difference in speed and even in the stability of the Internet connection. Naturally, this is absurd.

Secondly, the organizations themselves involved in the sale of such devices also cause confusion. Often in price lists, on price tags or on a sales receipt you can find the same model, which will be called either a router or a router.

Thirdly, many users themselves come up with non-existent differences between these devices:

• Some naively believe that a router differs from a router in the number of ports for connecting various peripherals.
• Others believe that the router has more features and is used as system equipment the provider itself, and the router is something like a home “set-top box”.
• Pseudo-experts also erroneously claim that a router and a router perform similar functions, and their differences are that the latter is not equipped with an antenna.
• Another misconception is that a router has a wireless connection, while a router only provides network access if there are wires.

The truth is that a router and a router are the same device that is used to create and maintain wireless networks. It can be compared to an electric tee or surge protector. Only instead of electricity, the router or router “shares” the Internet with laptops, smartphones, tablets and other devices connected to it.

Could these devices be any different from each other?

Of course, but only at the model level. Like two smartphones from different brands. Does one have any special functions, but in the other they are not. For example, specific model smartphone has powerful processor, allowing you to play top games and work with “heavy” applications, while the other can only barely provide Internet surfing. All this applies to our devices, where all differences appear only within the model range.

Therefore, if you need to purchase such a device, be sure to consider the following parameters:

The Internet world is full of all kinds of abbreviations and terms. Router and router, what's the difference? An ordinary person, concerned about the need to connect all of his “devices” on the global web, sooner or later he will encounter some confusion in the designation of the same device. In one store he will find a router with 4 LAN port Well, in another he will come across a router with WI-FI and for a moment it will seem that the problem has been solved and the difference is obvious. He adds 2 plus 2 and thinks he knows the difference between a router and a router. But the only difference is in the spelling, and the secret is simple. Router is an English word borrowed from Russian and means “router”. Bingo!

There is no difference between the concepts “router” and “router”, since both words refer to exactly the same device.

The essence is simple: the device is designed to distribute network content in a small space, creating a certain information network within, for example, one apartment. The router is doing important function. The very concept of data transmission involves the processing of network segments. At the same time, the load on the network is significantly reduced, which is impossible to do with a simple switch or switch. This device, having one input, divides it into equal output parts, which significantly slows down the network speed.

A router is basically a small computer and redistributes content streams. Even with a heavy load on the local network, it is able to provide normal work users. This is a definite plus in favor of the router.

Hardware looks different

1. You can have a so-called “lace” at the entrance to the apartment if there is a connection to the house fiber optic cable and the brave fellows from Rostelecom, having made one single hole in the wall, connected the required wire to the router, or, speaking in pure Russian, the router. The rest of the Internet distribution consists of entangling the entire apartment with wires; fortunately, 4 LAN outputs are provided for this purpose. This is the most proven and reliable way, in which there are no “jambs” of the following method.
2. You can connect with using WI-FI router that has USB port, a 3G modem is inserted there. Internet distribution is happening combined method, that is, the computer can be connected traditionally, by wire, through network card, but other devices (smart TVs, tablets, phones, etc.) are happy to connect via WI-FI. Some minus this method lies in the limited transmission of content due to a weak transmitting antenna and structural features. Those. The weak WI-FI may not reach the second floor.
3. The next method appeared relatively recently and requires special attention. These are the so-called “pure” 3G - 4G WI-FI routers. The devices have a SIM card slot inside and distribute mobile content. Moreover, you can have a miniature device that fits in your pocket and arrange a distribution via WI-FI for all those who suffer, or you can buy a more solid device, which will also have a familiar LAN port. This is for connecting a computer.

A thinking person who approaches the process of purchasing and installing a router responsibly should be guided by certain principles and rules, the observance of which will lead to the coordinated operation of all devices connected to the Internet.

How to connect and configure a router

You need to find the installation location of the router. It should be equidistant from all potential users so that in the future WIFI signal was able to reach everyone who wanted it.

To enter the router settings, you should open any browser on your computer and type in address bar address of the web interface of your device model.

Setting up the router is very simple and intuitive. But it is still necessary to take some precautions. The first router setup involves entering WEB interface to the address indicated in the manual. Next you need to set passwords for the admin panel and WI-FI network

The next step is the most important for the subsequent work. The maestro provider, about whom not a word has yet been said, appears on stage. The login and password from the provider must be entered in the appropriate fields of the router menu. Information about this procedure is in the setup manual or (most likely) on the Internet.

Setting up the distribution itself, namely DHCP protocol regulating Internet connection. Basically, the router simulates one user who opens several different pages on the Internet.

After the router is configured, you need to remember to connect all the necessary wires to the LAN ports and check the distribution. If everything is done correctly, then LED lighting in WAN and LAN ports this will confirm.

At any stage of the settings, errors are possible and wrong actions, from which no one is safe. If the router is configured incorrectly or not as desired at first, there is always the possibility of rolling back to factory settings. Each model has a small hole on the back panel. You need to insert a thin object into it and lightly press the reset button. The router will return to its original state.

Progress in the field of computer science is off the charts. The emergence of improved models is growing like a snowball. How to navigate, what to pay priority attention to when buying a router, some will help general tips presented below.

To return the router to factory settings, you must press the RESET button.

1. Price. No matter how trivial it sounds, you need to understand main principle, embedded in determining the price category. You can't buy a normal router for ridiculous money. In general, this rule works. What does a "normal" router mean? Here you need to remember that a router is a kind of small computer with its own processor, RAM and firewall. The latest devices already have a dual-core processor. That is, if you buy a simplified model, then accordingly you may miss out on a lot. There will be no USB connector for a flash drive, reduced output gain, no protection from network attacks, but you never know what else will happen. As a result, the Internet connection freezes, breaks and is unstable.
2. Reviews. People won't teach you bad things. As a rule, someone has already been burned by a purchase and has laid out their thoughts for everyone to see.
3. You need to pay attention to the stability of operation: does the device freeze, does the speed slow down, or perhaps does not reboot at all. IN in this case there is a weak “stuffing” of the router that cannot cope with the network load.
4. About WI-FI. The fact is that the speed specified in the router, for example, 150Mb/s, is the upload speed, which does not correspond to the device’s reception speed, especially if there are several of them.

Equally important technical specifications. There are several of them:

1. Random access memory (RAM) - from 128MB and higher, the more the better.
2. Processor frequency – from 240 MHz and higher, for productive work the frequency should be at the same level. The brand of the processor may be different, but it is advisable to also, as they say, by ear.
3. FLASH - memory, not less than 16 MB.

This is the main thing to rely on. In addition, it is advisable to determine how many consumers the router is designed for without loss of upload speed, how many built-in or external antennas it has, which ultimately affects the signal gain.

Well-known, promoted brand. And this is not only for confidence in the purchase, there is also software support from the manufacturer in the form of all kinds alternative firmware and improvements released to the market from time to time. You just have to go to the website of the brand of the same name and you will find a lot of options for how the device works, which makes life easier when the system “falls”. In this case, the non-name router is simply thrown away.

Buy a router in China and count on its adequacy in Russian networks not worth it.

There may be pitfalls here in the form of, for example, an untranslatable menu on Chinese. Or the inability to work in known 802.11 protocols. Either the absence of certain transmission frequencies, or their replacement with “Chinese” frequencies, in a word, you can get into a lot of trouble and it is not a fact that they will be overcome in the end.

https://site/

A few words in conclusion

As is clear, the difference between the devices is only in the name. But remember that the router must be modern, with support for 802.11b/g/n/a, with the ability to connect a 3G modem, with several WI-FI antennas. This should be a well-known model, promoted and tested on the Internet by more than one user, with its own website and the ability to replace firmware. Accordingly, the price for this “device” will not be small, for which you need to be prepared.

Even people far from high technology are familiar with the words “router”, “modem” and “router”. Moreover, if you have accessed the Internet at least once from a computer or laptop, you have used at least one of these devices. But which one exactly? Let's try to figure it out, and at the same time find out what the Internet is delivering in your home.

What is a router and what is it for?

The router, router and modem are designed to transmit Internet signals to users' devices.

They just do it in different ways. Such a network can be local or with Internet access. If we are talking about a household router, then its task is to distribute the incoming signal between several consumers: computers, laptops, tablets and other gadgets. These devices are connected both wired (via an Ethernet cable) and via a radio channel - via Wi-Fi.

How the router works

Where does the router get the signal from? It is provided by the Internet provider with whom you have entered into an agreement. It is the provider who owns the cable that enters the premises from the street and is connected to a special connector on the router (WAN port blue). The router plays the role of an intermediary: it receives an incoming signal from one source and distributes it to several consumers. He does this according to a strictly defined principle, using a routing table.

The routing table is stored in the router's memory and contains a list network addresses and a number of other parameters that are important in the operation of the network (masks, gateway addresses, interfaces, metrics). This table is something like address book– the paths to the devices connected to the router are written there. Addresses are selected in such a way as to provide the shortest path to the device, whose presence on the network is checked at a specified interval. Internet data packages are transmitted only to active consumers. That is, if you turn off your computer or smartphone (as an option, turn off data transmission in them), very soon the router will “find out” about this and stop transmitting data to the address to which this device corresponds.

How devices interact with the router

Wired devices - and most often these are PCs that do not have their own Wi-Fi module - are connected to the router via cable, through LAN ports, which are highlighted in yellow for clarity. Devices that have wireless module, - these are almost all laptops, smartphones, tablets and some TVs - are connected via a radio channel (via Wi-Fi). The number of connections available for one router is limited. However for home use in 90% of cases a simple and inexpensive router model is sufficient. But at wireless connection There is another important limitation - speed. It is determined by the power of the antenna and the supported Wi-Fi standard, but it is also influenced by external factors - for example, the presence of thick walls between the router and the Internet consuming device can reduce the data transfer speed.

What else can a router do?

The router does not only distribute the Internet to several consumer devices. IN modern models there are others, no less useful and interesting features. For example, some routers perform the function of firewalls - “ firewalls" These "screens" check data packets to see if they belong to an existing connection. If the router sees a discrepancy, it means that a virus is breaking into the network, masquerading as a harmless service. On routers famous manufacturers– Asus, D-Link, TP-Link and others – this function is called SPI (Stateful Packet Inspection).

To configure the router, a web interface is used, in which any user with basic knowledge work with a PC, easily set the desired network operating parameters. USB ports on the body of this device are needed to connect a printer or external storage device. In the first case it will be a full-fledged network printer, and in the second - network disk storage. Post on external drive files, and they will be available to all devices on the network, or arrange for downloading files from the network to it (for example, on torrent services).

Router and router are the same thing

Anyone who carefully read the previous text probably noticed the phrase “routing table” there. It was said above that it is the router that builds it. Therefore, it received another name - router. And the router is a transliteration of the name of this device ( routerin English.). Both words are used with approximately equal frequency by technical specialists, and regular users The Internet prefers the word “router”.

What is a modem and how does it differ from a router?

If modem turned out to be another name for a router/router, the article could be finished. But a modem is a different type of device, although it is also a network device. Those users who were born before 1990 have probably heard characteristic sounds, with which ADSL modems signaled a successful connection to the Internet. Such devices were used by everyone for whom cable networks were not available to access the network - at the turn of the 90s and 2000s they were an unheard of luxury. ADSL modems were connected to telephone line then to convert the analog (in this case telephone) signal into a digital one - understandable by a computer or laptop.

Converting a signal from one type to another is the main function of the modem. Unlike a router, it transmits a signal to only one device - for example, a PC or laptop. In this case, the modem is not assigned its own IP address (unlike a router), and a computer is identified on the network by the address of its network card.

If ADSL modems are already worthy of becoming museum exhibits, then mobile (3G and 4G) modems, on the contrary, are in great demand. Instead of a telephone line they use mobile signal mobile operator. And they connect to computers and laptops via USB connectors on the case. Mobile modems are compact and this is a big plus: they can be used not only at home, but also in the park, in transport - wherever there is coverage of the selected cellular operator.

By the way, we come across modems much more often than one might think. Today there are hybrid devices - modems with router functions. They not only distribute the incoming signal between several devices, but also pre-convert it. Also, routers and modems sometimes work in tandem. For example, if there is a USB port on the router case, you can connect to it mobile modem for 3G/4G networks. Since the latter is physically unable to distribute the Internet to several devices simultaneously, this task the router will take over. This is convenient when it is impossible to organize the usual cable connection or there is no desire to get confused in the wires laid around the office or apartment.

What kind of device distributes the Internet at your home?

We are sure that you have already received the answer to this question yourself, but just in case, we will voice it again. If an external cable is connected to this device, it is either a classic router or a modem with router function. If the signal enters the building wirelessly and the Internet connection is used on one device, it is a classic mobile modem for 3G or 4G networks. More precise information about network equipment Your internet service provider will provide it to you. You can also find out which device is suitable for servicing the number of devices you have at home. Often a family of 3-4 people owns the same number of smartphones, a couple of tablets and one laptop or PC. And the TV also needs the Internet, and some smart kitchen gadget is about to need it - for example, Samsung and LG are already releasing smart refrigerators with Wi-Fi! If you are just planning to connect to the Internet, visit the OnLime online store - we have routers, hybrid devices, PLC adapters and other equipment that you will need to organize a home network.

By the way, this article describes common features network devices and ways to identify them. Seeing how technology is developing in digital world, we would not be surprised if in 2-3 years the concept changes, and new hybrid devices will serve Internet consumers.

Important information about routers, routers and modems

• Router and router are two names for one device.
• The router distributes the signal between network participants, and the modem only decrypts it and transmits it to one device.
• The router has its own IP address, but the modem does not.
• Router – multifunctional device which supports fine tuning, the modem performs one function.

Router - what is it and where is it used?

Hello.

Every modern Internet user should know what a router is. After all, with its help you can connect to the Internet most quickly, conveniently and stably. All necessary information You will find information about this device, including its types, operating principle and selection principles, in this article.

A router is...

Through routers, humanity enjoys such a benefit as Wi-Fi. You will say that the connection occurs through a router? Right. So what is the difference between a router and a router? No. It's the same thing, it's just that "router" is a more rooted English word that means "router" in Russian.

In scientific words, it is a specialized device with two or more network interfaces, the task of which is to send data packets between different network segments.

It’s easier to translate this into understandable language using the example of what role it plays when connecting to the Internet. Therefore, read on.

What is it for?

Let's say you wanted to bring Internet to your house. The provider runs one cable into your home. But you use not only a computer, but also a smartphone, tablet, and want to organize wireless communication with a printer. Theoretically, you can connect a cable to each device. However, this will not only be expensive, but also wires will spread throughout the house, which does not look aesthetically pleasing. What to do?

It is necessary to connect the cable to one access point, which will distribute the Internet to all devices. The router plays its role. Thus, its purpose is to distribute the Internet over the air, which it receives through the provider’s cable or mobile network.

In particular, a broadband router allows two or more computers to receive data packets from the Internet under one IP address at once.

The functions of the router are not limited to this. It is also necessary for organizing wireless local network. That is, thanks to it you can exchange data via Wi-Fi between gadgets and control them remotely.

For example, you don't have to use a USB cable to download photos from your phone to your laptop or command the printer to print a document from your computer. All this can be done wirelessly, but provided that each device has a Wi-Fi adapter.
You can also organize a bridge between two access points, but not all models are suitable for this purpose, but only those with support for this option. This is necessary to expand the range of routers.

Operating principle

Do you want to know how exactly the router distributes the Internet? The essence of the work lies in the name of the device. It assigns routes for data flows to connected devices, distributing speed evenly among them.

Technically it happens like this: internal memory The router has a routing table in which the most optimal paths to gadgets are selected. To do this, the router periodically sends test requests to each of them, thereby calculating the time it will take for the data packet to reach the recipient. That's how they work DHCP servers- the most popular dynamic routers.

But there are situations when it is necessary to register paths manually in order to set the exact address for a certain equipment. This helps to avoid errors in table synchronization, and thereby ensure a more stable and secure connection. This way of working is called static routing.

Types of routers

First of all, routers are distinguished by the Wi-Fi connection standard. On at the moment There are 5 of them. The name of each begins with 802.11, but differs in the letter at the end (a, b, g, n, ac). The difference between them is the data transfer speed. This is also influenced by the number of antennas.
For example, the fastest and most modern is the 802.11n standard. If it has 1 antenna, the speed will be 55 Mbit/s, 2 - 110 Mbit/s, 3 - 165 Mbit/s and 4 - 220 Mbit/s.

As for other standards, then:

• “a” is used primarily by providers;
• “b” practically never occurs anymore, since it has a low speed;
• “g” works faster, but by today’s standards is no longer relevant;
• “ac” has just recently begun to be implemented, but it is also still used only by Internet providers.

When purchasing, keep this rule in mind: the speed of the router should not be less than that provided to you by your provider. Otherwise, you will only get the one that your device allows you to work with, and you will pay more.

Other characteristics

Knowing the basic parameters that routers have and, in fact, differ, it will be easy for you to choose the right one for yourself. So:

• Range of data reception and transmission. For home and office use, 2.4 GHz devices are purchased, which are marked with the number 2. Less popular are 5 GHz devices (standards “a” and “ac”). They are often used by providers to supply the Internet when it is impossible to install wires. Such devices are marked with the number 5. There are routers that support both of these bands or others, for example, 3 GHz.

• Data encryption standards. Often, modern routers support standards such as WEP (the most vulnerable to hacking), WPA (includes 128-bit encryption keys), WPA2 (the size of the keys is 2 times larger than the previous version).
• Number of LAN ports. The router can distribute the Internet not only over the air, but also through cables. There are special connectors for them, the number of which varies. Usually connected via wires desktop computers and equipment such as a printer, scanner, etc. Depending on how much you have, choose the number of LAN interfaces.

• Signal strength. If you live in big house and you plan to install the router behind several load-bearing walls from the place where you often spend time on the Internet, you need to take a device with an antenna of at least 5 dBi.
• Network connection type. Are you going to access the Internet via a mobile network? Then you will need a 3G/4G/LTE router. For cable connection ( twisted pair) you need an Ethernet model - this is the most popular option, and the optical fiber is connected through SFP devices. In villages and the private sector, EPON/GEPON/GPON routers are used.
  Less common models are xDSL - works via telephone cable, DOCSIS - through television, and simply Wi-Fi, which connects to the provider wirelessly.

Additional features

Routers can also have advanced functionality, namely:

• Built-in Firewall. Protects your connection from hacking.
• Availability of a USB port. Through it you can external drives, peripheral equipment, mobile modem as an additional access point.

• IPTV support. To watch Internet TV channels.
• Built-in torrent client.
• Traffic Shaper. Sets priorities in the distribution of data channels.
• VPN tunnel support. Thanks to it you can create virtual network with a remote office.

I think now you will not have a problem choosing a router according to your individual needs.
