What is the network connector (LAN) for on the TV? Why do you need a LAN connector on a TV (LG, Samsung, Sony)? Lan exit what.

If you look at a regular router, on the back panel we will see several ports with a LAN signature and one with a WAN signature. Externally, all these ports are identical, but for the functioning of the router, confusion between them is unacceptable.

Definition

WAN— Wide Area Network is a global computer network that covers and connects many computer systems around the world.

LAN— Local Area Network is a local computer network that unites a limited number of computers in a relatively small area.

Comparison

The difference between WAN and LAN lies in the purpose of the networks. WAN is an external network that connects groups of local networks and individual computers, regardless of their location. Network participants can interact with each other, taking into account the limitations of connection technologies (mainly data transfer speeds). The global Internet is the most famous, but not the only WAN network today. LAN is a local network, internal, connecting individual computers, network segments and groups of networks located in close proximity to each other. Interaction with each other is ensured by both wired and wireless technologies.

Thus, on routers, the WAN port is for connecting a cable with an Internet connection, and the LAN ports are for connecting your local devices.

LAN networks can cover up to several kilometers of territory, and communication between network sections is provided by high-quality, high-bandwidth cables (most often twisted pairs). WAN networks do not limit the territory, but their organization also uses telephone lines that do not differ in the quality and speed of data transfer. In addition, WANs can be based on more modern communication networks. When organizing a LAN, a direct topology is used; when organizing a WAN, a mixed hierarchical topology is used.

At the data link level of the OSI model, LAN and WAN networks use different data transfer protocols: for LAN these are Ethernet and 802.11 (as a rule), for WAN - PPP, HDLC, Frame Relay. In LAN networks, the communication channel is used by one client; in WAN networks, the communication channel is shared between network clients.

Difference between WAN and LAN

  1. WAN is an external, global network, LAN is an internal, local network.
  2. WAN is not limited to a territory; LAN cannot be very long.
  3. In routers, the WAN port is for an Internet connection, and the LAN port is for local user devices.
  4. The number of LAN clients is limited.
  5. LAN bandwidth is usually higher; high-quality cables are used to organize it.
  6. LAN uses Ethernet and 802.11 protocols, WAN uses PPP and others.
  7. In a LAN, the communication channel is used by one client, in a WAN - by several.

For inexperienced users, creating a local network at home is quite problematic, but only the right combination of devices will allow you to enjoy all the advantages of WLAN, LAN and Powerline networks, avoiding their disadvantages.

A well-built local home network will allow you to stream a movie from a laptop or PC to a TV, simultaneously use a media player in the next room and use mobile devices by your family members. To achieve this goal, it is necessary to achieve uninterrupted wireless network, stable data transfer speed in a bunch of Powerline adapters, or hide the network cable so that no one remembers about it. Let's get started creating a fast and well-configured home network.

Methods for achieving optimal speed

Creating an ideal home network is accompanied by a combination of 3 technologies: WLAN, LAN And Powerline using the strengths of each. By using modern Wi-Fi equipment on your network, you can get high and stable wireless connection speeds and eliminate the use of wires.

ORGANIZING A HOME NETWORK

Wireless network

The optimal location and configuration of a wi-fi router will increase the speed of all devices. New supported models can be used as fast radio bridges.

Optimal location of the wi-fi router. Place your WLAN-enabled wireless router so that it is clearly in the middle between all the devices you want to connect wirelessly. Now you can test the network coverage in your apartment using the Ekahau Heat Mapper utility installed on your PC or laptop. First, walk around the area you want to measure and figure out how to plot the plan on the Heat Mapper grid. Go to the starting point and start mapping the coverage. After each step, mark your location on the grid. When you've finished creating your map, right-click. On the grid, hover over the router icon to view the WLAN signal distribution. If you see yellow and orange zones, then you will need to strengthen the signal using my recommendations. It is worth following the rule: the higher the router is in the room and the further it is located from the walls, the less interference occurs during signal transmission.

Tall cabinets and shelves are perfect for installation.

Organization of a wired network (LAN) Connecting the switch.

A Gigabit Ethernet network (1000 Mbps) will be the best solution for the home, but 4 ports of a wi-fi router may not be enough. To add ports, use a switch (for example, D-Link DGS-1005D) to relieve the load on the router, but keep in mind that the connection between the router and the switch takes up one port on each device. Devices that need to quickly communicate with each other, such as a computer and a home server, need to be connected to GIGABIT ETHERNET. The uplink connection to the router and the Internet can be made via a Powerline network or a slower but easier to install flat cable.

What is an Uplink connection? It is a connection in a network of computers, from a device or a small local network to a large local network. Local network (LAN) structure.

  • When using two switches there are 2 options:
  • connect both devices directly to the router

To cover long distances, connect one switch to another, since there can be a cable up to 100 meters long between two switches. Connecting an RJ-45 outlet

. To connect the cable, you may need wall sockets with RJ-45 LAN connectors, let's look at the connection method.

  • The pin terminals are labeled with numbers from 1 to 8. Connect them to the color-coded wires as follows:
  • 5 - blue-white, 6 - green, 7 - brown-white, 8 - brown.

The terminals have sharp edges into which it is best to push the cable using a pressing tool until the edges cut through the insulation, make contact, and cut the end of the cable. Check the connection before installing the outlet.

Connecting an HDMI cable

How to extend HDMI? Unlike LAN cables, it is recommended to use HDMI interface wires no longer than 15 meters. The way out of the situation is an extension cord - for example, which transmits an HDMI signal through a LAN cable up to 30 meters long. However, high data transfer rates require two of these cables. Connect the adapter labeled “Sender” to the HDMI port of your source device (such as a laptop or Blu-ray player). Connect the Ethernet connectors “DDC” and “TMDS” of the adapter to the ports of the same name on the “Receiver” adapter and insert it into the required device.

HDMI signal transmission via wireless network. An HDMI extender will help you place your devices (Blu-ray player, TV receiver and game console) near your TV or projector and allow you to place them in a convenient place. This device transmits Full HD images and surround sound via radio to the TV receiver. At the same time, it receives signals from infrared remote controls and sends them to source devices. Audio and video devices can be located up to 30 meters away and even in another room.

Most modern TVs are no longer just repeaters of analogue or digital television; they now have such features as Smart TV, communication using Skype and much more. But most of the new functions that have appeared are based on one primary thing - 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 Internet on TV, the primary task that arises immediately after its purchase. 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. All that remains is to connect it and configure it. There are two ways to connect your TV to the Internet:

1 Using a network cable;

2 Using a wireless Wi-Fi connection.

Connecting a cable to a TV is not as simple as it might seem at first, since you need to understand where this cable comes from and where one of its ends is connected. And here there are two options:

1 Network cable is connected to the router;

2 The network cable comes from the entrance (provider cable).

Let's look at each option in more detail.

Connecting the TV to the Internet using a network cable from your provider.

This method does not require any additional devices and initially 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 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 contract with the provider or calling technical support. Next, I propose to analyze each of the connection technologies:

Dynamic IP. If your provider uses Dynamic IP, it requires minimal effort from you:

1 Connect the network cable from your provider to the TV;

2 Make sure your TV is using Automatic search for network settings.

As an 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 remote control, press the "Input" button.

Select the gear icon.

Then select "Network" - "Wired Ethernet Connection". There you should see “Connected to the Internet”, if so, then congratulations, you have set up the Internet on your TV.

If you see the message “No Internet connection via Ethernet”, select this connection and make sure that it is set to receive network settings automatically.

Static IP. With this connection method, you need to find out your network settings from the contract with the provider and register them in the TV settings. We do everything step by step:

1 Connect the provider’s network cable to the LAN port of the TV.

2 Go to the TV settings and enter the network settings of the provider.

For example, on LG TVs, click the "Settings" button, select from the menu - "Network" - "Wired Ethernet connection",

Uncheck "Automatically" and enter the IP address, mask, gateway, DNS issued by your provider.

PPPoE, L2TP. Unfortunately, not many TVs allow you to set up the Internet if your provider provides the Internet using PPPoE and 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 is already configured on the router (you can find out 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 goes into the TV.

Go to your TV settings. On LG TVs, to do this, on a regular remote control, press the "Settings" button

or the "Input" button on remote magic controls

and select the gear icon.

Go to the menu "Network" - "Wired Ethernet Connection" and make sure that below this inscription it says "Connected to the Internet."

If this is not the case, check that the TV receives network settings automatically by selecting an Ethernet connection. Click the "Edit" button.

And check the "Automatic" checkbox.

Thus, without much effort, using a LAN network cable, you can set up the Internet on any TV (LG, Philips, Samsung, Sony, etc.).

Video of connecting the TV to the Internet using LAN, Wi-Fi.

Hello, dear readers! This article is the first in the “Smart Home” section. The goal of the new section is to describe in simple words the basics of interaction with modern devices in our home.

For example, take modern televisions. Nowadays, it is already quite difficult to find a TV without Smart TV technology, and even more difficult, it is almost impossible to find a TV without a LAN connector or a wi-fi module.

This is where the question arises: why are all these bells and whistles needed? Since you have to spend money on them, maybe it’s worth at the same time learning the benefits of these innovations? The answer is simple: “Of course it’s worth it!”

Obviously, the LAN connector is used so that the TV can be connected to the home network via a network cable. This is done so that network technologies can be used, no matter with or without Internet access.

So, let's briefly talk about the network technologies used in TVs. There are two of them. These are Smart TV and DLNA.

Smart TV technology

This technology allows you to connect your TV to the Internet, for example via a LAN connector, which we talk about in the article. Once connected, the TV can play streaming video from the Internet, and there are also a number of additional features, such as installing applications that will expand the functionality of the TV.

Here's a simple example. Connect your TV to the Internet, install an application to watch movies and TV series. As an option - Amediateka (this is an online cinema). After this, you have access to a huge number of different films and TV series in very decent quality. You can forget about cinemas :)

DLNA technology

If the TV is older and does not support Smart TV technology, it still most likely has a LAN connector. I'll explain why it is needed.

In addition to Internet access, you can also configure access to your home network. Let's say you have a media server at home. I mean a computer on which a lot of multimedia information (movies, music) is stored. By properly setting up the home network, we can make sure that the TV can access the folders with the content of this media server.

This procedure will help us watch movies and music downloaded from the Internet through an intermediary (media server) on TV.

Obviously, to connect the TV to the network we need a LAN connector. That is, even if the TV cannot be connected to the Internet, the presence of a network connector is still justified.

Conclusion

In the following articles we will talk in more detail about Smart TV technology, and about DLNA, and about setting up a home network and media server. Subscribe to site updates so as not to miss new interesting articles.

I also have a small request for you. Please write in the comments whether you would be interested in reading articles about the basics of organizing a smart home system in your home. Perhaps the audience of this site is not so interested in technologies that are at the forefront of progress. Or are they interesting? ;)
