I decided to make a short entry in which to answer one interesting question: what is the LAN connector on the TV for? Whether it's Samsung, LG, Toshiba, Sony, or some other manufacturer. Indeed, now in almost every TV you can find a regular, network Ethernet (LAN) connector. Everyone is used to the fact that the Internet is connected through this connector on the computer.
If a TV with Smart TV function, then, in principle, it is clear why you need a LAN connector - to connect the TV to the Internet. If, for example, there is no built-in Wi-Fi, whatever, and you need to buy an external Wi-Fi receiver. And as practice shows, the cable is always more reliable. If the router is not far from the TV, then you can also connect via cable.
But, if there is no Smart TV, what is the LAN connector for then? Which looks something like this:
And you need it mainly for work. You can look at the characteristics of your model, most likely, DLNA support is indicated there. Perhaps an Ethernet connection is required for some other function, or for a software update. It all depends on the manufacturer.
But mainly, it is watching movies, photos and listening to music via DLNA. You can read more about this technology at the link above. How it works: you have a router to which a computer is connected, or a laptop. You also connect a TV to the router (via network cable), and after a simple setup on the TV screen, you can watch movies and photos that are on your computer. You can also connect the computer to the TV directly, without a router.
And you can connect. It's even more interesting this way. If only a movie can be launched via DLNA, or a photo can be opened, then absolutely everything will be displayed on the TV via HDMI: desktop, folders, etc. Just like on a monitor.
Hello everyone! Perhaps the question in the title of the article seemed somewhat strange to you, but still there is a semantic load in it. Surprisingly, such questions bothered some of my readers and met me several times in various forums. Progress and competition in information technology a few years ago laid the foundation for the production of smart TVs. Many modern models (depending on the line) have a LAN connector on their board, but some consumers after buying a TV do not get what they expected from this network connector. So why is the LAN connector on the TV?
Recently, manufacturers have built a network Ethernet port into TVs not only with support for the Smart TV function, but also in those models where this function is not at all. If you do not know what Smart TV is, then watch this short video.
With TVs where the Smart TV function is provided, everything is clear, but the LAN connector on board for models where this function is not sometimes confuses consumers ...
Having delivered their cherished dream home from the store, they try to connect it to the Internet and are surprised to find that there are no applications and no browser in it. Hmm, but it also has a network LAN input, which means there is an Internet connection.
However, in this situation they are partly right ... There is indeed an Internet connection, but for completely different purposes, but first things first.
Having grounded in certain knowledge, you have a much higher chance of buying exactly what you want, and not what others will advise you.
Secondly, if you have already become the owner Smart TV TV, then in this case you have access to the Internet via the LAN input and various "goodies". You can connect the TV directly (using the provider's cable) or via, and if there is a built-in Wi-Fi module, then via wireless network... If in the Wi-Fi line you see the inscription: "Optional", then there is no built-in wireless module, but you can connect an external Wi-Fi adapter from the manufacturer.
The TV does not have a Smart TV function, but there is a LAN port.
On one of the forums, a person wrote that his TV does not connect to the Internet, and after he indicated the model, it turned out that there is an Ethernet port in the model, but there is no built-in browser ... After a while, a similar discussion appeared on the site in one of the discussions about connecting a TV. Both on the forum and in the comments on the site, it turned out that this port can only be used for flashing the TV and, at the same time, there may not be any smart options in it.
I do not know how much it is advisable to update the firmware over the network, although it is of course convenient, but I have heard more than once from experts as recommendations that it is better to update the TV software not via the Internet, but USB stick(and). The point is that the update software over the network can lead to its incorrect installation, and the previously downloaded update to the drive from the official website during installation has a minimal chance of failure. But the last word belongs to the manufacturer. Is not it?
On my own I will add that it is quite possible that the presence of a LAN connector in the TV can be used not only for updating the firmware, but also for DLNA technology. Look at the characteristics of the TV and if you see support for this technology there, then you can connect the TV to a computer and transmit media streams. That is, you can either through the Ethernet port and media content on the TV (photos, videos).

There is a LAN port, but there is nothing to expect from it - some glitches from updates.

Actually, the Ethernet port is for network connection and through it you can connect your soundbar to your home network, and through it ... P.S. And what prevents to repair?

Zhadaev Andrey, I don’t understand who offers people to create a server for transmission, the question is why ???? If you can connect via hdmi and use the TV as a monitor! There is one way to find the firmware that fits with the browser, flash the TV and try, if there is an input, then there must be an output!

I am very sorry that in society there are still "specialists" from your words, who cannot personally determine the presence of certain functions from the technique. Trust that a flash drive and a media server are different things and provide different conveniences. Since the appearance of such a TV in the house, I completely forgot about flash drives and use them only outside the house. It is very convenient. Typically, modern TVs have browsers, but budget models can be limited by hardware or software. Until!

So I am concerned with such a question. Two TVs, both have a LAN port, but how to use it is not written. The master came - connected the Internet and included television. And he doesn't know. He suggested that the TV should have a browser and advised him to contact the manufacturer. But it turned out that you can create a media server on your computer and broadcast the data to the TV. Somehow not practical. It turns out that you have to pull a line to the TV, have the TV and the computer on in order to watch the video. Isn't it easier to dump it on a USB flash drive and watch it on TV? No wires needed?
Several times I have met questions about Internet connectors on modern TVs. They say why is there a LAN connector on the TV, or why an Internet connector, if there is no Smart TV. So I decided to write a small note in which to clarify the situation a little, and tell what's what.
Yes, now almost all modern TVs have a LAN connector. And on those TVs that support the Smart TV function, and those where this function is not. If with TVs that have Smart TVs, everything is clear, the network connector is there for connecting to the Internet, then with those where Smart TVs are absent, everything is not so clear.
And very often, having bought a regular TV without Smart TV, people try to connect it to the Internet, look for this very button to open the browser, etc. When you answer such comments that there is no Smart TV on such and such a model, they immediately write to you : “Why then LAN connector? So everything is there, but you don't know how to set it up. "
So look if your TV has Smart TV technology, and you can find out about this by looking at the characteristics of your TV (and preferably on the official website) then the network jack is actually used to connect the TV to the internet. You can connect, or directly from the provider. But, in this case, problems may arise. If you connect the cable directly from the provider, then see the article. There I wrote about possible problems. 
Also, I advise you to look in the specifications to see if your TV has a built-in Wi-Fi receiver. If there is one, you can also connect to the Internet via Wi-Fi. According to the instructions. If there is no Wi-Fi, then only by cable. And if it says something like “optional”, it means that you can buy and connect a branded, external Wi-Fi receiver.
And if there is no Smart TV, why then a LAN connector?
Most likely it is there to use DLNA technology. Here's a look at the characteristics of your TV model. Most likely, DLNA support will be indicated there. In a few words, then DLNA technology allows you to network your TV, computer, and other mobile devices. So that you can watch movies, photos, or listen to music, which is, for example, on your computer's hard drive. This is not an Internet connection, this is a local technology.
For more details on DLNA, and how to configure this technology, you can see in separate articles:
Well, we figured out what the network connector on the TV is for, which arouses such great interest among users.
Most modern TVs have ceased to be just repeaters of analog or digital television, they have such features as Smart TV, Skype communication and much more. But most of the new functions that have appeared are based on one paramount - access to the Internet from the TV. It is thanks to Internet access that you can fully use Smart TV, watch movies from the Internet, chat on Skype, add and use other TV functions. How to set up the Internet on your TV, the primary task that arises immediately after purchasing it. In this article, I will show in detail how to connect a TV (suitable for any TV - LG, Philips, Samsung, Sony, etc.) to the Internet using a LAN cable.
Almost all modern TVs have functionality that allows them to access the Internet. It remains only to connect and configure it. There are two ways to connect your TV to the Internet:
1 With a network cable;
2 Using wireless connection Wi-Fi.
Connecting a cable to a TV is not as simple as it might seem the first time, because you need to understand where this cable comes from, where one of its ends is connected. And here there are two options:
1 The network cable is connected to the router;
2 The network cable comes from the entrance (provider's cable).
Let's take a closer look at each of the options.
Connecting the TV to the Internet with a network cable from the provider.
This method does not require any additional devices and at first it may seem that everything is simple, but this is not entirely true. The thing is that providers use various connection technologies, for example PPPoE, L2TP, Dynamic IP, Static IP. The settings that need to be made on the TV in order for the Internet to work there depend on what technology your provider uses. You can find out what technology your provider uses by looking at the agreement with the provider or by calling technical support. Next, I propose to disassemble each of the connection technologies:
Dynamic IP... If your ISP uses a Dynamic IP, a minimum of effort is required from you:
1 Connect the network cable of the provider to the TV;
2 Make sure your TV is using Automatic search network settings.
For example, I will describe how to do this on LG TVs with webOS.
Press the "Settings" button on a regular remote control.
If you have a remote magic, press the "Input" button.
Select the gear icon.
Then select "Network" - "Wired Ethernet". There you should see the inscription "Connected to the Internet", if so, then congratulations, you have configured the Internet on your TV.
If you see the inscription "No connection to the Internet via Ethernet", select this connection and make sure that it is set to automatically receive network settings.
Static IP... With this method of connection, you need to find out from the contract with the provider your network settings and register them in the TV settings. We do everything in steps:
1 Connect the network cable of the provider to the LAN port of the TV.
2 Go to the TV settings and register the network settings of the provider.
For example, on LG TVs, click the "Settings" button, select from the menu - "Network" - "Wired Ethernet",
Uncheck the "Automatic" box and write down the IP address, mask, gateway, DNS, issued by the provider.
PPPoE, L2TP... Unfortunately, very few TVs allow you to configure the Internet if your ISP provides the Internet using PPPoE, L2TP technologies. And for most, the way out of this situation is to use a router to connect the TV to the Internet.
Setting up the Internet on the TV when connected via a router.
For this method, it is necessary that the Internet has already been configured on the router (you can find how to configure the router in other articles on our website). Connect one end of the cable to any LAN port of the router.
The other end of the cable is into the TV.
Go to the TV settings. On LG TVs, for this, on the usual remote control, press the "Settings" button
or the "Input" button on the remote magic remotes
and select the gear icon.
Go to the menu "Network" - "Wired Ethernet" and make sure that below this inscription says "Connected to the Internet".
If this is not the case, check that the TV would receive the network settings automatically by choosing an Ethernet connection. Click the "Change" button.
And check the "Automatic" checkbox.
Thus, without much effort, using a LAN cable, you can set up the Internet on any TV (LG, Philips, Samsung, Sony, etc.).
Video connecting the TV to the Internet using LAN, Wi-Fi.
Good day.
In this article, we will analyze what is the local network, why it is needed, how it is organized and what types it is. Such a network can be useful to you, so do not pass by.
Definition
A local network is one that unites several computers in a small area. This concept, translated into English, looks like a Local Area Network, therefore it is often abbreviated as LAN.
The network can be located within one apartment, office, computer class, small organization or its department. By this I want to say that usually it does not include many computers and they are not at a great distance from each other.
Let's say you can organize a home network if you have a stationary computer, laptop, printer, a couple of mobile gadgets, a smart TV, etc. This option is also convenient, for example, for an enterprise where there are 10-20 computers located on different floors. ... Or for example / private house.
Why do you need a local area network?
LAN may be needed for:
- Data transfer between devices without the participation of external storage devices (flash drives, disks, etc.);
- Opening access to the Internet for all network participants if it is connected to only one computer;
- Management portable devices from different computers. For example, within the office from any hardware, you can print on one printer;
- Organization of voice and video conferencing;
- Network games.
Types of local networks
There are only two of them:
- Peer-to-peer network. All participants have equal rights, that is, they independently decide which files to open access to, and which not. It is used in cases of combining a small number of PCs.
- Server based. Actual option when there are more than 10 computers. Increases network performance. The bottom line is that for storing general information, connecting peripheral devices (scanners, printers, etc.), determining routes for sending information and centralized management of the entire network, one machine is allocated - a server - and all the rest are fed to it.
There are also two ways to build a network: with or without wires. Let's consider each separately.
Wired connection
A twisted pair or optical cable is used, which is connected to the PC. Such devices are found in any hardware that is no more than 10-15 years old - they are integrated into the motherboard.
The wired connection provides the most stable and fastest data transfer. In modern versions throughput is 100 Mbps and above through twisted pair. From 10 Gbps over fiber. For such a connection, Ethernet technology is most often used.
When the set of computers is large or it is necessary to distribute the Internet from one server, hubs (switches) can be used. They have several connectors for connecting wires. Their functions include relaying the signal entering one port over other interfaces.
Network structure
There are several topologies for connecting computers over wires:
- Linear bus is a serial connection of a PC from one to another.
- Star type - all network members are powered from one server.
- Ring - the structure of the connection is clear from the name. In this case, server resources are also distributed among all machines, but if one fails, the others will not work.
- Snowflake is the most flexible topology, because it allows you to connect equipment according to the most convenient principle, usually taking into account its functionality.
Wireless way
This refers to the association by radio waves. The most common option now is this. However, it is also possible to connect via Bluetooth and GPRS. In any case, the speed will be lower than with a wire connection. On average, for Wi-Fi it is 10 Mbps and higher.
To create a mesh without the use of wires, you need a special module in the computers. In modern laptops, it is usually built-in, but for a PC you can buy an external device. You also need a single network gateway (router) to which the wired Internet will be connected. And the network participants will receive it via radio waves.
How is data transferred?
To organize a local network, it is not enough just to physically connect the machines, you still need to perform the configuration. Their work is controlled by programs. In order for computers to understand each other, a single and understandable language is used - the network protocol.
It can be of different types, but packet protocols are the most widely used. What does it mean? The transmitted data is divided into blocks, which are placed in the packet. It also contains recipient and recipient information. Each computer connects to the network with a certain frequency and checks the passing packets: it picks up those that are intended for it.
How does the hardware know that this or that packet is addressed to it? Each machine has an IP address that is unique within the same network. It is set in the process Windows settings or whatever system you are using.
