How to Connect a Router to a TV Through Cable

How to Connect a Router to a TV Through Cable

Modern smart TVs can be connected to the internet. Various sites, applications, viewing and listening to content online become accessible from the TV screen. In order for the TV to have access to the network, you can simply go to the Wi-Fi home access point, or you can use a wired connection through the router itself or direct connection (Internet cable directly to the TV).

What you need to connect the TV to the Internet via cable

To establish a wired connection, you need:

  • The provider’s cable, which comes from the entrance either from the modem in your apartment, or a LAN cable (if we connect through a router);
  • Smart TV with LAN
  • Router (if a direct connection does not suit you);
  • Internet access availability (paid tariff);
  • Type of network. Ask your provider what protocol it works with: call technical support or look at your contract with the company. Protocol options: PPPoE, L2TP, PPTP, dynamic IP, static IP.

Pros and cons of this connection method

What good can be in cable Internet connection in principle? Why this bunch of wires if you can use Wai-Fay? Yes, you can, but firstly, not all TVs have built-in Wi-Fi modules. If you are a fan of wireless, but the TV does not have a module, you will have to buy it separately.

If you need to use the Internet not only on TV, but also on your PC and phone, connect the TV to the Internet using a cable through a router

Secondly, data is transmitted much faster via a wire than via Wai-Fay. Almost all routers cut speed. Plus, they have to distribute the signal to several devices at once. The signal and speed are divided between participants in the local network.

Thirdly, cable connection is more stable than wired. Failures in data transmission will occur less frequently.

Network cable can be connected directly to PC

The disadvantage of the method, of course, is the number of wires. They do not always fit into the interior. Over, it is inconvenient. If the router and the TV are far from each other. Even more so. You will either have to buy a long cord, or rearrange the router closer to the TV.

If you do not have a router and you do not want to use it, but there is a provider cable, you can insert the cable directly into the TV. You won’t have to buy a router. If the TV is not equipped with a Wi-Fi module, direct cable connection will be the only budget option.

Router or direct connection. What to choose depending on the Internet protocol

The most important criterion that determines the type of cable connection is the protocol. If you have a dynamic or static IP, you can safely connect to the TV directly. At the same time, a cable and router connection will be available.

If you have PPPoE, L2TP or PPTP, only a router is suitable here. The TV does not recognize these types of connections.

Cable TV Connection Diagrams

We will show and tell you how to connect a TV to a router or just to the cable of an Internet provider.

Through the router

If you decide that you need an intermediary in the form of a router, do the following:

Using a special cord, you need to connect the router to the TV


Everything is simpler here: the provider cable is immediately connected to the LAN port on the TV. The cable can go directly from the entrance or from the street, from the splitter (if it is an ADSL telephone connection. The splitter disconnects the signals for the phone and the Internet) or from the modem (it is configured by the provider’s specialists when connected).

TV setup for wired connection directly or via a router

After a physical connection, you need to configure the TV to receive an Internet signal.

How to set up TV with “Dynamic IP”

If you have the Dynamic IP protocol, the Internet on the TV will be configured automatically after connecting the cord. This will be indicated by a message on the screen “Established a connection to a wired network”. If the message does not appear and the Internet does not work, go to manual debugging (for example, Samsung Smart TV):

  1. Go to the device menu. Select the “Network” block.
  2. Open the item with network settings.
  3. For Network Type, specify the cable connection.

Select the Cable menu

Click on “Connect” to establish a connection.

For TVs from other manufacturers, the setting principle is the same, but there will be a different interface. Some sections may be called the same. The most important thing is to find the block with the settings for the network or network connection (usually indicated by a globe). In LG, for example, you must first click on “Configure Connection”, then on “Configure manually.” Then select a wired connection.

Click on the pink button “Configure Connection”

How to set static IP and DNS on the TV

If you connect the Internet directly and use the “Static IP” protocol, after the basic setup of the TV (which was described in the previous section), you need to register the data from the agreement in the TV settings: IP address, DNS addresses. Where to write them:

  1. After the basic configuration of the wired connection, go to the “Connection Status” section (Status).
  2. Next, click on IP Settings / Settings.

Go to IP settings

Enter all data from the contract

How to find out the MAC address of the TV

Direct connection may not work for you if your ISP uses MAC address binding. The provider has a MAC device (its physical number), to which the Internet was previously connected (your router, PC). Now you have decided to change the device, so the provider needs to inform the new MAC. Of your TV, so that the company supplies the Internet now to this device too.

How to find out the MAC address of the TV? This unique code is, of course, in the documentation for the TV. Or you can see the address on the screen of the device itself. If you have Samsung, go to the “Support” section, under “Product Information” there will be a “Model Code”. This is the MAC of your TV.

You can find out the model code through the “Support” block

How to configure a router for IPTV

You have connected the TV to the Internet through a router and now you need to configure the IPTV function to view digital channels via the Internet. How to do it? You need to go into the web interface of the router with the settings at or Further, the procedure will differ depending on the manufacturer of the router. For example, on the new TP-Link firmware, the IPTV (Multicast) function is turned on automatically. No debugging is necessary.

If you have Asus, you need to activate multicast routing in the LAN section.

If you have a Zyxel Keenetic router:

  1. To combine the work of the Internet and IPTV, you need to create a pair of interfaces and bind them to one WAN. For example, IPTV is provided over VLAN 10, and access to the Internet over VLAN 100 (you may have other data. Contact your provider or study the information in the contract).
  2. Create a new IPoE connection with VLAN 10 (port for IPTV). To do this, go to “Internet”. IPoE and add a new interface with a VLAN ID of 10.

Mark two items under the blue connector

Specify VLAN ID

Cable Internet is faster than wireless. This is its main advantage. You can connect the wire directly to the TV or use an intermediary. A configured router. If you have dynamic or static IP as a protocol, you can use a direct connection or a router, and if PPPoE or L2TP with PPTP, you will have to buy a router.

For a long time on the market there are so-called SMART TV. Smart TVs. Their peculiarity is that in addition to broadcasting the usual television, they have Internet access. Connecting to special network resources, such a TV is enriched with additional functionality. Weather forecast, you tube, fitness, zoomby, skype, and a huge number of additional programs. And, of course, a simple Internet browser for ordinary Internet surfing. But after buying a TV, you must configure it to access the network, and since in most cases a home computer is connected to the Internet, this article will teach you how to connect a TV through a router.

Depending on the manufacturer, smart TVs have different connection interfaces, which can be divided into the following categories:

Of course, you can not do without the usual antenna input RF in for cable television. Recently, they began to abandon obsolete SCART ports, CI slots and composite connectors (bells).

  • Connection in a router
  • Ethernet TV connection
  • Wi-Fi TV connection
  • There are three options:
  • Additionally, you can familiarize yourself with the settings on the tutorial:

Connection in a router

So, we have the following diagram. The ADLS channel enters the apartment, the connector of which is connected to some multi-port router, to which the computer is connected to access the Internet. The router is equipped with a Wi-Fi adapter. Our goal is to connect the TV to this router so that both the TV and the computer have access to the network (or several computers, it does not matter).

There are at least two connection options. Via Ethernet port (wired), or via Wi-Fi (wireless). First, consider a wired connection.

Ethernet TV connection

We take the router in our hands and look at the back panel.

We find LAN ports. They are usually signed.

It may happen that there is only one LAN port, and it is already occupied. In this case, we use the hub and switch to “multiply” the port.

Next, take the patch cord, connect one end to the free LAN port of the router, the other end to the Ethernet port of the TV.

Turn on both devices. On the TV remote control, press the “Settings” button. Select the menu item “Network”, then the submenu “Network setup: wired”.

On the remote control, click “OK”, and go to the second step. Setting the network address of the TV.

The IP address can also be configured manually, but this is only necessary in rare cases when the computer network requires it (static address, non-standard subnet mask, etc.). If such requirements are not advanced, then we can safely set the mode to “Auto IP”, and the TV will coordinate its address with the router without your participation.

The same goes for the DNS server. Leave it on auto-tuning. Click OK.

Everything, a wired connection is established, you can access the Internet directly from the TV by running the built-in web browser.

Wi-Fi TV connection

But it’s much more convenient to set up a Wi-Fi wireless network. It is more convenient in many respects. There are no wires spoiling the interior, tuning is performed without getting up off the couch, in some cases the transmission speed is higher (standard “n”). Consider how to connect a TV to a router via Wi-Fi.

First of all, read the instructions for the TV whether it is equipped with a wireless Wi-Fi module. If yes. Lucky, if not. You need to purchase a separate Wi-Fi adapter.

We connect it to any smart TV USB adapter.

Next, go to the TV menu. In the “Network” menu, the item “Network Settings: Wireless” appears. We select it.

The TV will offer several options for further settings.

There are three options:

When you select the second item, a list of available networks appears, select the necessary one.

If the wireless network is password protected, a window appears asking you to enter it.

Click OK. That’s it, the wireless connection is established.

In this section, we consider the possible difficulties of connecting via Wi-Fi.

The first possible nuisance. I can’t set up Wi-Fi. To troubleshoot, we take any wireless device (laptop, smartphone, tablet), and install software on it to directly connect a TV to it. This software is on the TV installation disk, or can be downloaded from the manufacturer’s website. For example, for a Samsung TV, such a program is called AllShare. After installing the software, we try to connect directly to the TV (the third item in the menu). If it works. Wi-Fi is fine, if not. The conclusion suggests itself.

The second reason is that on some TV models the automatic network search function is disabled. Carefully read the instructions and check this parameter.

The third reason is that the network is installed, but there is no Internet access. Check the DHCP server on the router, try disabling it and setting the TV to a manual IP address. IP address, subnet mask, gateway # router address #.

The third reason is to make sure that the purchased Wi-Fi adapter is really compatible with your TV model.

And the last, universal, advice. Try turning the TV and the router off and on again, at times it helps to adequately detect each other.
