Is there a wireless router? What is a router? How is a Wi-Fi router different from a router? How a wireless Wi-Fi router works

Nowadays there are a huge number of different Wi-Fi routers from different manufacturers on sale. And that’s good, there’s plenty to choose from. But immediately after purchasing a router, we need to install, connect and configure it. And if the connection process is practically the same depending on the model, then the setup process itself and the page with the router settings can be different even from the same manufacturer.

It is very difficult to give detailed and step-by-step instructions on setting up different models in one article. But I'll try. In this article I will describe in detail and show how to install and configure a Wi-Fi router. Regardless of what manufacturer and model you have. This universal instruction is suitable for both setting up a new router and re-configuring it. You can do everything yourself. And you don’t have to pay specialists for setup.

Login to the router settings. How to log into the web interface?

Each router has its own web interface (website with settings, control panel), which can be accessed through a browser by going to the appropriate address.

Important! To go into the router settings and configure it, your device (PC, laptop, smartphone, tablet) must be connected to the router via cable or Wi-Fi network. At the same time, there may be no access to the Internet on the computer. You don't need internet to log into the control panel!

If you have a high-speed connection on your computer (maybe with your provider's name), then after connecting through the router there is no need to start it!

To enter the settings we need find out the address our router and factory username and password for authorization. This information is located on the body of the device itself. It looks something like this:

On a computer or mobile device that is connected to the router, open a browser (Opera, Chrome, Yandex.Browser, etc.) and go to the address indicated on the case. Or try 192.168.1.1 and 192.168.0.1.

Important! We enter the address in the address bar, and not in the search bar. Many people get confused and instead of a page with settings they end up on a page with the search results of some search engine.

On the login page you need to specify a username and password. The factory settings are indicated on the device body. Most often these are admin and admin. On some models, the default settings are not protected, and immediately after logging into the control panel, you need to set a login and password.

If the settings page has opened, we can continue. If not, then see the article with solutions to this problem at the link above.

How to set up a Wi-Fi router?

In order to use the Internet through a router, you need at least:

Set up an Internet connection.
Set up a Wi-Fi network.

In most cases this is enough. I also recommend changing the password that protects the router’s web interface. There are also settings for IPTV, USB drives, parental controls, etc., but not everyone needs them.

In the control panel of almost every router there is a so-called “Quick Setup Wizard”, also known as “Quick Setup”. On some devices, it opens immediately after logging into the control panel. With its help, you can configure your Wi-Fi router step by step. Internet connection, wireless network, etc. For example, what it looks like at TP-Link:

You can try it, it's very convenient.

Internet setup. The most important step

The main thing is correctly configure the router to connect to the provider. If he cannot connect to the Internet, then all devices will have a “No Internet access” connection. Many users who try to configure everything themselves most often encounter problems at this stage.

Each Internet provider uses a specific type of connection. Dynamic IP (DHCP), Static IP, PPPoE, L2TP, PPTP. This type of connection must be specified in the control panel of the router, and certain parameters provided by the Internet provider must be specified.

Important! You must know exactly what type of connection your provider has. Also all the necessary data for connection (Username: Password), if they are necessary. As a rule, this information is specified in the contract that you received when connecting to the Internet.

Some providers bind by MAC address. It would also be desirable to clarify this.

If your provider uses a “Dynamic IP” (DHCP) connection, then the Internet should work immediately after connecting, since this type of connection is set by default on routers.

If the Internet through the router is already working (and you haven't run any connections on the computer), then you can skip this section and go straight to setting up Wi-Fi.

When the connection type is PPPoE, L2TP, PPTP, or Static IP (which is very rare), then you need to set the necessary parameters. Usually, this is the login and password that your provider gave you. In the control panel, the section with these settings is most often called: “WAN”, “Internet”, “Internet”.

For example, what the PPPoE connection setup looks like on an ASUS router:

Other examples:

Target: so that the Internet through the router works on all devices. Via cable and Wi-Fi. If this does not happen, then there is no point in continuing the setup.

You can always call the provider and clarify what parameters should be specified and where. They help many people over the phone.

I hope everything worked out for you.

Changing Wi-Fi network settings

I highly recommend changing your Wi-Fi network name and password. It is also advisable to set your region. Everything is simple there. This can be done in the section with wireless network settings. It can be called differently: “Wi-Fi”, “Wireless network”, “Wireless”, “Wireless mode”. If you have a dual-band router, then the settings must be set separately for the network at 2.4 GHz and 5 GHz.

In the "Network name" (SSID) field you need to enter a new name. In English letters.
In the "Password" field (wireless network key) create and write down a password. Minimum 8 characters. Security type - WPA2 - Personal.
Well, there should be a “Region” field there. Change it to yours.

If something doesn’t work out for you during the setup process, you can always reset the settings to factory defaults and try setting everything up again. Find the “Reset” or “Reset” button on the case, press it and hold for about 10 seconds. The indicators will tell you when the reset occurred.

You can leave questions in the comments. I just have a small request, describe the problem in detail. Write the router model. Otherwise, it’s very difficult to understand and advise something when you don’t understand the question itself. Best wishes!

In this article we would like to tell you what WiFi technology is and how wireless Internet access is achieved using Wi-Fi routers. Nowadays, almost every person has the Internet at home. The Internet can be connected on a smartphone, tablet, laptop and other devices that a person uses outside the apartment (at work, on the road, etc.).

So, what is WiFi technology? There are quite a few ways to connect to the Internet, but in general, the network can be classified into wired and wireless connection technologies. In the first case, the connection occurs using an optical or network cable (you can find out at the link). In the second case, various wireless data transmission channels are used, for example, GPRS, 3G/4G and Wi-Fi. This article will focus on the process of connecting devices via a Wi-Fi network. We will also describe the operating principle of a Wi-Fi router.

What is a Wi-Fi router and why is it needed?

In simple terms, Wi-Fi is a connection organized through a special radio channel (it is through it that all data is transmitted from one device to another). On many modern laptops and tablets you can see the corresponding sticker. Having noticed it, users think that together with this device they will immediately buy the Internet (they will not have to connect it separately and pay money for it).

In reality, things are a little different. A sticker or “Wi-Fi” icon on a laptop only means that there is a module inside it that can receive the corresponding signal from another device. That device, in turn, must also take this signal from somewhere, for example, from a fixed access point or from a wired channel of an Internet provider. As for stationary Wi-Fi points, they are most often created in crowded places, in some public institutions (thereby attracting people to these institutions). A public hotspot is usually free, meaning it can be used by everyone without exception.

Also, an ordinary Wi-Fi router (or, as it is also called, a router) can be an Internet access point. Outwardly, it looks like a small box with antennas sticking up. To put it simply, the router’s task is to receive a wired signal (wired Internet) and distribute it over several routes. Each route is intended for a separate device, for example, a desktop computer, laptop, smartphone, tablet computer, etc. Any modern Wi-Fi router can encrypt the network using various types of encryption: WEP, TKIP, CKIP, WPA And WPA2. If you are interested in the topic of setting up and connecting WiFi, we recommend reading our following instructions:

— article about setting up WiFi in Windows, it also talks about setting up a router using the example of a router D-Link.
— a detailed article about connecting WiFi in Windows, iPhone/iPad, PSP.
— instructions for connecting a Wi-Fi router using the example of a router Trendnet.
— a second, more extended article about setting up a WiFi router at home.
— everything is clear from the name :), we connect via Wi-Fi to a printer that has this function.
— some laptop users do not know how to turn on the Wi-Fi module on their computer. The article describes in detail possible inclusion options.
— in this manual we describe in detail how you can find out the password for your Wi-Fi network if you have forgotten it or it is not entered.
— detailed instructions on how to get into the router settings.
- instructions using a TV as an example Samsung via Wi-Fi.

As you can see, wireless connectivity options are great and we have a lot of useful instructions for setting up WiFi at home. Let's continue our story about the main culprit - the router. Accordingly, the input connector of the router is the LAN port. This is where the internet cable is inserted. The output connectors are also LAN ports. As a rule, one router has about 4-6 standard LAN ports. Through them, all external wired devices are connected - PC, laptop, game console or something else. In addition, you can use a wireless Wi-Fi connection to connect devices (which is why the Wi-Fi prefix is present in the name of the router).

The total number of devices connected to the “box” can be quite large; for example, you can connect several laptops, smartphones, and tablets at once. When connecting new devices, you need to remember one important thing - on those devices that are already connected, there will be a commensurate decrease. Let's say only one desktop PC is connected to the WiFi router.

In this case, the Internet speed will be maximum (in relation to your tariff plan). If you connect another computer or laptop and use the Internet on it, the speed on both devices will be distributed evenly. If you connect a tablet or laptop, the speed on each device, subject to simultaneous use, will drop even more. That is, a drop in speed will be a significant drawback in the case when several devices are used simultaneously and the overall Internet speed is not too high. In other cases, you can somehow adapt.

When connecting and initially setting up a WiFi router, you may not specify the addresses of specific devices to which the wireless signal will be transmitted. In this case, the router will distribute IP addresses dynamically (based on which specific devices are connected). However, it is best to specify addresses and allow connections only for certain devices, for example, your computer and phone. This can be done by creating a password for the network. It’s not difficult and will take a minimum of time. If you don’t have a password, your network can be used by neighbors above and below, random passers-by on the street, etc. The more “left” devices connect to the network, the slower the Internet speed on your devices will be.

This concludes our story about Wi-Fi wireless technology. We hope that now you understand what WiFi is and why you need a Wi-Fi router. If you have any questions, please ask them in the comments.

Today, the Internet is available in almost every second apartment in our country. The Internet is developing at a tremendous pace, just as its transmission technologies are developing. If at the end of the nineties and until the mid-2000s, Internet speed was measured in kilobytes, at the end of the 2000s - in megabits, now there is a transition in calculating Internet speeds into gigabytes! If previously access to the Internet was carried out only via wires, now data transfer can also occur wirelessly.
Next we will consider the following questions:

Why do you need a Wi-Fi router?

A Wi-Fi router is needed to provide Internet access to several devices at the same time. That is, if you have several devices on which you want to configure Internet access, then you need a router. If some of these devices support data exchange using Wi-Fi technology, then you no longer need a simple router, but a Wi-Fi router.
A Wi-Fi router is a network device to which the Internet is connected in order to distribute it to several devices. Internet distribution is carried out both via LAN and Wi-Fi. Thus, if you have a computer, laptop, tablet, smartphone at home and with the ability to access the Internet, then a Wi-Fi router will help you. In those devices that do not have a Wi-Fi module, they connect to the router via LAN.

How to choose a Wi-Fi router

ManufacturerWi-Router Fi
In principle, the choice of router, first of all, must be made based on its technical characteristics, but the company also plays an important role. Therefore, we advise you to select router parameters, initially narrowing their choice to such companies as: ASUS, D-link, HP, TP-LINK.
Wi-Fi standard
The Wi-Fi network standard has 4 types:

802.11 a – transmits data at speeds up to 54 Mbit/s;

802.11 b – transmits data at speeds up to 11 Mbit/s;

802.11 g – transmits data at speeds up to 54 Mbit/s;

802.11 n – transmits data at speeds up to 600 Mbit/s;

802.11 ac – data transfer reaches speeds of over 1 Gbit/sec.

We recommend purchasing a Wi-Fi router with a network standard no lower than 802.11 n.
Maximum connection speed
Pay attention to such a parameter as the maximum connection speed so that the router does not limit your Internet speed. That is, if your tariff plan is, say, 60 Megabits, and the router’s bandwidth is only 30, then the channel will be cut by half by the router. Try to choose a Wi-Fi router whose actual connection speed will exceed the speed of your tariff plan. In addition to the official data on the speed of the router, there are real ones, which you can find out from user reviews on the Internet.
Router and DHCP server
Router (Router) - provides simultaneous access to all devices connected to it. The DHCP server assigns an internal IP address to each device connected to the router, this allows you to connect several devices using one external IP address.
The router sets up work with the provider, or as they say “raises the connection”, and is a buffer between it and your home network devices.
Wi-Fi range
Wi-Fi network range – a parameter that determines the boundaries of the Wi-Fi network coverage area. This indicator is abstract, since it is calculated from ideal conditions (no walls and partitions, no radio or magnetic interference, etc.). Therefore, if the manufacturer indicates the range of the router to be 100 m, then in real conditions (in an apartment) the range will be approximately 20 m. To ensure stable operation of the Wi-Fi channel, give preference to a router with a wide range. Please note that the better the quality of the Wi-Fi network, the higher the data exchange speed.

Antennas
The data transfer speed depends on the number of antennas in a Wi-Fi router. If the device has one antenna, then it works both for receiving and transmitting data, and when connecting other devices to Wi-Fi, the router will need to reduce the speed to ensure correct operation of data transmission.
Two antennas in the router work as follows - one for transmission, the other for reception, which allows you to separate streams and at the same time maintain maximum speed.
A Wi-Fi router with three antennas works in this way: one antenna for reception, the other two for transmission, and due to this, a stable and high data exchange speed is ensured.
The maximum possible number of antennas in a Wi-Fi router is 6 pieces. Accordingly, the more antennas in the device, the better the Wi-Fi network will work.
When choosing a Wi-Fi router, make sure that the antennas in it are removable, as this will allow you to install more powerful separate antennas instead to increase the coverage area of the Wi-Fi network.
Data encryption method
To ensure that no one can connect to your Wi-Fi network, data encryption is used. Today there are 2 data encryption methods: WEP and WPA. As a rule, the vast majority of routers include both of these encryption methods, but the WPA encryption method is considered the best - it is more reliable.
Availability of USB interface
The USB connector in the Wi-Fi router allows you to connect other devices to it. For example, you can connect an external hard drive or flash drive in order to open access to the files on it for all devices on the network. You can also connect a printer to the USB connector to provide access to other network devices. You can also connect a 3G modem to the USB connector, but for this the router must support this function.
Possibility of connecting a 3G modem
The presence of a USB interface in a Wi-Fi router does not mean that it will work with a 3G modem; a special feature must be implemented for this. If you have this feature, you can share access to 3G Internet across several devices. This is necessary for those who do not have the opportunity to connect to a landline provider, or 3G Internet is a substitute option in case of problems with a landline one.
ADSL support
If you are connected to ADSL Internet, we recommend purchasing a Wi-Fi router with ADSL support. Thanks to this, in addition to routing, your router will also perform the functions of an ADSL modem, and you will not need to use 2 devices: an ADSL modem and a Wi-Fi router - both of these devices will be in one.
Number of switch ports
Another important parameter is the number of switch ports. As a rule, most access points include 4 Ethernet ports, thanks to which you can also build a wired network. For example: you can connect desktop computers, a TV, a receiver to Ethernet ports, and a smartphone, tablet and laptop to Wi-Fi, and all these devices will be on the same network, just connected in different ways.
Remember that the speed of data exchange via Ethernet is better and higher than via Wi-Fi, which is why it is better to connect stationary computer equipment via Ethernet.

Port speed
As we said above, today the data exchange speed is calculated in gigabits. Most providers provide a maximum Internet access speed of up to 100 Mbit/s, but technologies are developing and therefore, very soon, Internet access speeds will be in the hundreds of megabits, and for this you need a Wi-Fi router that will support gigabit networks.
If you are an active Internet user, we recommend choosing a router whose port speed (WAN and LAN) is 1000 Mbit/s; this will allow the router to remain relevant for as long as possible. If you are going to watch HD quality movies on your TV that are on your computer, then your local network connection should also be gigabit. But keep in mind that such routers are much more expensive.
If you do not need high speed, then give preference to a router with a speed of 100 Mbps.
Web interface
Thanks to the presence of a Web interface, you can configure the router through a browser, that is, the settings menu will be in the form of a Web site.
Possibility of flashing
As a rule, all routers have the ability to update software (firmware). In essence, firmware is the operating system of a device that organizes its operation. New firmware versions include corrections of any errors in the operation of the device and expand its functionality. Therefore, choose a router that can be easily flashed and for which new firmware versions are created.

Today, many families have several different types of computer equipment: a computer, a laptop, and others that are often used. All devices need the Internet, and they like it to be a wi-fi connection. And for this you need a Wi-Fi router to provide Internet via Wi-Fi for all equipment.

Let's start with what is a Wi-Fi router?

Wi-Fi router (router) is a device for wirelessly connecting users to the Internet.

Router in English is router. And in Russian this word is translated as router. Therefore, a router and a router are one and the same.

It’s almost impossible to imagine any cafe or any office without wi-fi. In order to combine all these devices, a wi-fi router or router is required. And without it, it will simply be unprofitable or impossible to provide all this equipment with Internet access.

Why do you need a wi-fi router?

A Wi-Fi router, or otherwise called a router, is a device that helps build a common network between individual types of computer equipment (computer, smartphone, printer, etc.) and connect them to the Internet.

New router models are different in that they can restrict access to certain sites with a high probability of danger. They can also encrypt traffic, also to ensure information security.

A home router usually comes with an antenna, a hardware unit, a cord, and a power supply.

The router, by its principle, receives certain signals from the Internet and transmits them to computer equipment, printers, even refrigerators and other “smart” electronic devices.

To put this in simple words, a wireless router (Wi-Fi router) connects a mini-server connected to the Internet with user devices.

All devices individually receive their own IP addresses. Moreover, thanks to the enhanced signal, several connected devices can use the Internet simultaneously. For example, some of the newest router models have the ability to connect up to 100 different devices.

By transmitting information to a computer, wi-fi routers also work in another direction, that is, they send certain information back to the Internet. For security, all signals are encrypted using WPA protection.

What types of routers are there?

There are top, middle and bottom routers, if we consider the scope of their application. The first type includes high-performance models that connect networks of enterprises, firms and organizations.

Each device, designed to work in local (indoors, apartment, home, office) and global networks (connection to the “external” Internet, to an external network through one provider or several providers), can have about 50 ports.

The medium type is suitable for small networks. Such routers can have up to 8 ports for a local network and up to 3 for a global network.

And the lower type of routers is used for home use and the local network of a very small office, which can have up to 2 global network ports, and a local network - up to 4 ports.

As for the connection method, the router can be

like wireless,
and wired.

In our apartments they are still quite often used wired routers.

The wire from such a router is connected separately to each computer. The inconvenience is that the wires must somehow be routed from the router to the location of the computer or several computers. Each computer needs a separate wire from the router.

Wireless wi-fi router can be used

both wirelessly using radio signal transmission,
so with wires, as in a wired router.

Many consumer devices, with the exception of desktop computers, can support two types of connections:

wired via LAN connector and
wireless via wi-fi.

For example, some laptops may support both types of connections. Probably, the wired connection is already fading into oblivion and wireless is confidently coming to the fore.

About the local network

A wi-fi router has great capabilities in connecting many devices into a large network with an Internet connection or even without an Internet connection. You can establish communication between devices or equipment inside an apartment, home or office using a router.

A wireless connection within a local network allows the exchange of information without laying wires, which is often very convenient.

About connecting a Wi-Fi router

As practice has shown, a modern router is a durable and very reliable device. If you buy it and make the correct connection, then after that it can work for a long time without failures. There will be no need to reconfigure it or perform any other actions. As they say, I turned it on once and forgot for a long time!

Setting up the router is not difficult, and this procedure takes about 15-20 minutes. This can be done either by a representative of the provider or by the user himself using a disk that contains detailed instructions, or using the usual paper instructions that may be included with the router.

Some useful instructions for setting up the router and connecting to the router can also be placed directly on the router case in the form of stickers.

Sometimes I get asked something like this: send me step-by-step instructions on how to connect a Wi-Fi router on a laptop with the Windows 10 operating system. In this regard, I would like to draw your attention to a couple of points.

Rebooting the router is easy - you just need to disconnect it from the power supply, wait a few seconds (preferably a few minutes), and turn it on again.

Turning off the Wi-Fi router

Sometimes they ask whether it is worth turning off the router, for example, at night, and in general, how often it should be turned off.

The router does not need to be turned off, it can work constantly, that is, be constantly connected to the 220V network. If you wish, you can turn off the router, for example, at night, if this makes you sleep better, say, if the cute winking lights on the router panel are disturbing you.

To turn off the Wi-Fi router, you just need to disconnect it from the 220V power supply.

Electronics are designed in such a way that they do not like frequent switching on and off, so turning the router off and on often (for example, several times a day) is not very healthy. The router should either not be turned off at all, or turned off rarely.

When leaving for a long time - on vacation, to the country, on a business trip, it is better to always turn off the router. Because a router connected to 220V is seen by your Internet provider as a working device, that is, from the provider’s point of view, you continue to use the Internet. And it follows from this that upon your return you will most likely have to pay for the service according to the provider’s tariffs, although in fact you did not use the Internet.

About choosing a Wi-Fi router

When choosing a router, you need to determine for yourself what purposes it will be intended for and take into account the capabilities of the device. You shouldn’t buy a complex, high-performance device for your home that, say, is designed to serve a large office.

Simple and cheap models are quite suitable for home use. You just need to carefully ensure that the router has both a wired connection (if needed) and a connection via wi-fi (again, if this is needed to connect computers and gadgets to the Internet via wi-fi).

Quite often, providers, when offering you Internet connection services, simultaneously offer certain models of routers, and this is a good offer, consistent with the capabilities of the provider. Providers don’t even always sell such routers, and sometimes they simply rent them out for money or even for free, just so that you become their clients.

You also need to take into account the features of various devices that you plan to connect to the Internet via a router. For example, old PCs or printers only have a single LAN port for a wired connection to the Internet, which means you need a router with a wired connection.

And laptops and tablets can be connected wirelessly using Wi-Fi, which means in this case you can use a router that distributes the Internet via Wi-Fi.

Results

The router does not increase the Internet speed provided by the provider. At best, the router will maintain its previous speed. If a router divides the Internet between several devices, then for each device the speed may be even lower than the speed provided (declared) by the provider.

Modern router models support high Internet speeds, approximately 100 Mbit/s. For many, this speed is more than enough to surf the Internet comfortably and quickly.

There are routers that have enormous speed and functionality. Despite this, they operate more simply than other switches, such as telephone modems.

But if there are many devices (computers, laptops, gadgets) operating on the office network, then constant monitoring by specialists may be required to ensure that the operation of the routers is synchronized. Basically, users who install routers at home do not have such problems.

At the moment, routers are quite common, and therefore a large number of manufacturers are starting to create entry-level devices that will subsequently replace complex routers of the upper classes. And life will become even simpler, the Internet will be more accessible.

Comments: 16 to “What is a wi-fi router, what is it for and how to use it”

The provider said that the speed on my tariff plan is up to 100Mbit/s and they cannot provide more. This prefix “up to” 100Mbit/s is what 50, 60, 99...

Up to 100Mbit - this means from zero to... Much depends on the provider’s equipment, on the routing (signal passage) from the provider to your apartment, on who else is connected “on the route” and how these users use the Internet.
Still, before experimenting with an additional router or with the settings of an existing router, I would swap the TVs to make sure that the second (old) TV lacks the Wi-Fi signal strength. Otherwise, everything else may turn out to be meaningless.
And if the signal strength for the second TV is not enough, then I would first adjust the TV to receive a lower-quality signal. From experience working with video and TV, freezes are eliminated primarily by reducing the quality of the transmitted image.
Manipulating the router is unlikely to yield anything. Although you can try, why not?! The main thing is that if something happens, you can return to the previous settings of the router.
Also, if you go through the router settings, keenetic may offer to update its software. You need to be mentally prepared for this. I agreed to install updates twice (at different times). And everything went well. Although the second time, at some point, at the very end of installing the updates, the router completely disconnected: both from the Internet and from the computer (from which I installed the updates). I had to turn off the router, and then turn it on again after a short pause. Everything worked out this time, and the router started working with the updated software.
Installed keenetic updates do not affect the Internet speed or Wi-Fi signal strength in any way...

Thank you Nadezhda for your answer. Maybe dig into the router settings. For example, increase its signal transmission power to 100% or try to send the signal only through the 5GHz channel. It’s interesting how a long-distance TV receives a signal through this channel.

Good afternoon. That's the problem. I live in a panel apartment building. Purchased a zylex keenetic air WiFi router. Internet provider Wifire. For the New Year, we bought a new Samsung TV and placed it in the room where the router is located. And the LG TV, which previously stood in this place, was moved to another room. The router was left in place, the Internet was connected to it, and the provider’s box was taken to LG. Both TVs are smart and have the Wifire tv app installed on both TVs. Question: On the second LG TV, the picture periodically freezes. What to do. The distance from the router is about 6m through three walls. Speed on LG 26-32 Mb/s.

Hello. 6 meters from the router to the TV is not much. A keenetic router usually “breaks through” a solid wall normally. If there are 2 main walls on the way, I don’t know, I haven’t tried it, there may be a problem with signal transmission.
The problem with the picture freezing most likely does not arise due to the distance from the router to the TV. It’s just that before you bought a new TV, the signal from your router only went to 1 TV, but now it goes to 2 TVs. The signal and its speed are now divided in half. If both TVs are working at the same time, then the Internet speed from the provider may not be enough. More often than not, it will be the TV that is located far away that will react to the lack of speed.
Try not using the new TV and see how the old TV behaves. If the freezing on the old TV stops, then the problem is that there is not enough power of the router or Internet speed from the provider to service 2 TVs at the same time. TV is a serious load on the Internet. And 2 TVs are even more serious. Most likely, it’s still not enough speed from the provider, and not the power of the router; keenetic can’t handle anything like that.
For 2 TVs, it is better if an optical fiber goes from the provider to the apartment, rather than a wire. I don't know how it is with you. If a wire comes from the provider, then, I repeat, there may not be enough speed (power) for 2 TVs. The carrying capacity of the wire is much less than that of optical fiber.
If the problem is the Internet speed from the provider, then you can try changing the tariff to one with higher speed, even on a wire (but it will be more expensive).
Or you can try to adjust the quality on a second TV remote from the router - reduce the picture quality if the TV settings allow this. Then the amount of Internet traffic consumed by the second TV may decrease, and freezes may stop (there will be no need to change the tariff and no need to pay more). At least on a computer, if you watch TV on it, reducing the picture quality helps eliminate freezing of TV programs.
Wired connections are always faster than radio communications. Fiber optic connections are even faster. This has to do with the way signals are transmitted. By radio is one way, by wire is another way, and by fiber optic is a third way. Every time the connection gets faster and faster.
The signal strength of a wireless connection, of course, matters. But not everything depends on signal strength. There may be a strong signal, but at the same time a poor connection, for example, if a lot of users are simultaneously connected to the radio channel and are actively “downloading” information, for example, watching videos. Or the signal is strong, but at the other end the provider, say, has problems with the server for connecting to the Internet, and here again a strong signal will not help much.
