Why use a wired connection?

The need for a wired connection to the router occurs in the following cases:

  • There is no Wi-Fi module in the PC;
  • Network adapter is broken;
  • When configuring the router;
  • When updating the firmware;
  • When the speed of the Wi-Fi connection is insufficient.

The speed of work may not be enough, for example, if is being processed over a local network, working with files from a network attached storage. A Wi-Fi network can be loaded with a wireless surveillance system. If the PC or laptop is not far from the router, and other devices or users are actively using the Wi-Fi network, then a wired connection will be a good solution.


If you don’t feel like reading, watch the following:

To connect a laptop or PC, connect one end of the network cable to the LAN port on the router. Usually there are four such connectors, but there can be one, there can be more than four. It depends on the router model. You can connect to any free port, not necessarily the first.

Connect the other end of the patch cord to the network connector on your computer or laptop. If in laptops the network connector is usually integrated on the motherboard, then not all modern computers have it. If there is no connector, you will have to purchase a special adapter that connects via USB.

Actually, this is where the physical Internet connection through the router ends. If the wire for connecting the computer to the router is not damaged, the LED corresponding to the connected port will blink on the last one. If the provider cable is connected to the WAN port of the router, and the router itself is correctly configured, the computer will automatically gain access to the Internet. This will be signaled by the corresponding icon on the taskbar in the lower right corner of the screen.

Problems that may occur when connecting

When wired to the router, there may be two types of problems. The lack of a physical connection and incorrect hardware settings. Let’s consider in more detail how to overcome possible difficulties.

There is no connection between the computer and the router

If the red cross appears on the network connection icon in the panel in the lower right corner of the screen, and after connecting the patch cord from the router to the computer, it does not disappear, this means that the physical connection could not be established.

First of all, you need to make sure that the connectors at the ends of the cord are fully inserted into the connectors on the router and the computer. You need to insert the connectors until they click easily. So they are tightly fixed in the connectors. You can try plugging the cable into another LAN connector on the router or another network connector on the PC, if you have one.

If the connectors are firmly inserted into the connectors, but there is still no connection, you need to check if the cable is working properly. It can be bent or pinched, which entails a rupture of the conductor under the shell. Possibly crimped connectors.

If all else fails and there is no connection, check whether the network adapter is connected to the PC operating system. In the Device Manager in Windows you need to find “Network Adapters” and make sure that the device is working properly. If there are any problems, then a menu is called up by right-clicking. There you should select the desired item. Or just turn on the adapter if it is disabled, or reinstall the driver.

Connection without internet access

Watch a with instructions that will help you access the Internet through a router:

The most common problem is the lack of a computer connecting to the Internet through a router. This is indicated by an exclamation mark in a yellow triangle on the network connection icon in the lower right corner of the screen. The reasons for this may be a lot. From incorrect router settings to a banal disconnection of the Internet for non-payment.

To localize the problem, you need to check whether the Internet works on other devices connected to this router via Wi-Fi, for example, a smartphone. If everything is in order with the router, then the problem is in the computer settings. Very often IP addresses are spelled incorrectly.

In order to adjust the settings in the “Control Panel”, you should find the “Network and Internet” section, there in the “Network Connections” call the context menu by right-clicking on the “Local Area Connection” item. Then you should go to the “Properties” submenu, select “Internet Protocol Version 4” there and select “Properties” again. Here you need to select the option to automatically obtain IP and DNS addresses.

Connecting a computer or laptop to the router is easy. If problems arise, they can be overcome independently if the correct recommendations are clearly followed.

Good day to all!

As a rule, when you connect and configure your home Internet, you need to go to the router settings at least once by connecting to it with a network cable (via a LAN port). At least in order to set up a Wi-Fi network.

In general, usually, problems arise more with Wi-Fi setup than directly with connecting to the router’s LAN port. However, in some cases, interesting “incidents”: when I connected the computer and the router with a cable, but the network icon in Windows for some reason says that there is no connection. The cable is not connected (and a red X is lit on the icon).

In general, in this article I will consider in sequence all the steps for connecting a PC / laptop to the router’s LAN port. I think this article will be useful to all novice users who are trying to set up a home network.

Connecting to a router with a network LAN cable

I’ll start right off the bat.

1) The first thing we need (except for the router and PC, of ​​course). This is a network cable. In general, usually, such a cable is bundled with a router (in 99% of cases). Most often, the length of such a LAN cable [from the set] is no more than 1 ÷ 2 m. This length is quite enough [in most cases] to connect and configure the router.

Network cable (1-2 m cable is included with all routers)

2) Next, connect the power adapter to the router and turn it on. Then connect to the jack “Internet” cable of your Internet service provider. One of the blue (often they are yellow) ports (LAN) must be connected to the network LAN port of the laptop / PC.

How to Connect a Computer to a Router Through Cable

Typical type of router (D-Link)

With computers, as a rule, there are no problems. Most models have at least a built-in mat. The board is a network card, and its port is easy to find on the back of the system unit.

With laptops. It may be a little different. The fact is that modern laptops usually connect to the Internet using a wireless network, and not all devices have a LAN port. If you do not have a LAN port. You need to purchase specials. Adapter adapter to USB.

There are a lot of adapters: there are ports suitable for both classic USB 2.0 / USB 3.0, and there are more universal (with LAN, HDMI, USB support) for USB Type-C. See the screenshot below.

Various options for laptop network adapters (for connecting to a router via a LAN port)

3) If both the computer and the router are turned on, everything is in order with the cable. Then on the router case you should see how several LEDs light up (blink): those responsible for power, LAN port, Internet (if the connection is established).

The LEDs on the router light up (including the LED responsible for the LAN port)

4) Ideally, you should see the network icon of the network in the tray without any warning (signaling that the connection to the router is established, the Internet is there).

Network Icon (Windows 10). Everything is OK!

But, unfortunately, in some cases, it is far from always that the router automatically starts working immediately (sometimes without manual configuration. No way).

Why after connecting to the network network icon “burns” exclamation mark (no internet access)

Perhaps this is the most popular option (especially when connecting and configuring the router for the first time, for example, after changing equipment).

In this case, the first thing I recommend to open network connections and check if everything is okay there. To do this, press a combination of buttons Winr and use the command ncpa.Cpl (see screen below).

How to open network connections || ncpa.Cpl and WinR command

In the network connection window, you must open the properties your connection (usually called “Ethernet” (as in my case) or “LAN connection”)

Next, find the line “IP version 4” and discover its properties. After putting the sliders in mode:

  • Obtain an IP address automatically;
  • Obtain the DNS server address automatically (in some cases, it is recommended that instead of the auto-option, specify DNS This is DNS from Google. About this here).

Save the settings and check the network.

IPv4 Properties. Get IP address automatically

The second important point. This is checking the settings of the router. If you have not previously configured it. Then, in principle, in most cases, the Internet will not exist until connection parameters are specified. Different providers have different requirements: as a rule, you can find the necessary logins and passwords, IP addresses, etc. Parameters [which you need to enter in the router settings] in the agreement with the provider, which you entered into when connecting to the Internet.

In this regard, I will recommend another article (about setting up and connecting a router with “scratch”) You can draw everything from it “omitted” moments. https://ocomp.Info/nastroyka-routera-tenda-fh456.html

Why after connecting to the network network icon “burns” red cross

The network cable is not connected. Red cross (Windows 10 tray)

Such an icon means that you do not have a connection between the router and the computer (laptop). This can happen for various reasons. Below are the most common ones.

1) Check cable condition.

Is everything okay with him, aren’t they bent. It often happens that, externally, the cable may seem intact, but it was bent several times, and inside the copper veins were broken. Therefore, I would recommend trying a different cable.

The cable is kinked (twisted)

2) See if the cable is firmly inserted into the LAN port.

Often due to small manufacturing deviations (as well as rubber pads, which are often placed on them, roughness, etc.) RJ-45 connectors and LAN ports. Not always and not every connector is fully inserted into each port. Ideally, after the connector has been inserted. You should hear a slight click (and on the network card of the PC / laptop. The LED should light up that the cable is connected (the same as on the router)). If the PC has several LAN ports. Try another one.

3) Check if your network adapter is turned on.

On Windows, it may happen that the network adapter is turned off. To check if this is not the case, go to network connections (for this call the window “Run” WinR combination, and use the ncpa.Cpl command). Next, pay attention to which icon: the device is turned off, it is black and white (as in the screenshot below).

Turn on the adapter / network connections

I also recommend going to the device manager (combination of WinR, and the devmgmt.Msc command) , and find your adapter in the tab “Network adapters”. Next, try turning it off / on (just click on it with the right mouse button). An example is shown below.

Disable-enable device (device manager)

To help!

If this does not help, I recommend that you read one of my past articles, which understands why the Internet may not work on the network cable from the router. https://ocomp.Info/ne-rab-internet-po-set-kabelu.html

That’s all, all a successful and fast connection!

How to connect a Wi-Fi router to a computer? This question is “tormented” by most novice users who first brought home the treasured box with a new (or not quite new) modern router and now have no idea how to use the miracle of the modern network industry.

However, those who want to “quickly” connect the Internet to a computer via a wifi router and plunge headlong into the vast expanses of the global virtual network will have to be a little disappointed: in addition to directly connecting, you will also need a special configure the router via the web interface devices.

At the same time, each model has its own “subtleties”, therefore, we considered this issue separately in the Networking section ”, which provides instructions for most modern routers.

In addition, you can use the site search to view information on other models of routers or Ask a Question in the section specially designated for this.

However, despite the functional differences and features of the web interface, most models directly connect a Wi-Fi router to a computer in the same way, and in this article we will examine in detail how to connect a router to a computer via a network cable.

How to connect a computer to a router through a cable?

To connect a wifi router to a computer (or laptop) over a twisted pair cable, you will need:

  • – network card with Ethernet RJ-45 socket. For most computers and laptops, the Ethernet module is built into the motherboard;

Before connecting a Wi-Fi router to a computer, you must disconnect the Internet cable from the PC (if it is connected, and only one Ethernet adapter is installed in the computer).

Next, to independently properly connect the router to the computer, follow this instruction:

  1. Step 1. Connect the power supply to the 220 V power supply network and to the router in the corresponding socket (usually it is designated as DC, Power or 9V). You can “power up” models with a micro-USB power connector using the computer’s USB port.
  1. Step 2. Connect the patch cord to the “LANx” jack (where x. 1, 2, 3.) of the router.
  2. Step 3. Connect the other end of the cable to the PC (Ethernet port).
  3. Step 4. At this stage, the operating system should determine the connection. Your router is successfully connected to the PC. Next, you need to install the correct network card settings forWindows XP or Windows 7/8.

If in addition to the computer you plan to connect peripheral network devices to the router, read the instructions how to connect the printer to a Wi-Fi router.

What should I do if the connection to the router is not detected by the OS?

  1. 1. The patch cord is not correctly connected to the router. Make sure that it is connected to the LAN port. A distinctive click should be heard when connecting.
  2. 2. The Ethernet adapter is disabled in the operating system, or there are no drivers for this component. Make sure the network card is not turned off and correctly detected.
