How to connect your computer to the router via cable

How to connect a computer to a router with a cable

On the subject of connecting to the Internet via a wireless network have written many articles. Instructions on how to connect, find solutions for various problems, errors, etc. д. And in this article we will look at connecting the router to the computer with a network cable, which usually comes with the router. It’s a lot easier with a cable connection than it is with Wi-Fi. But despite this, sometimes there are issues with the connection to the router with a network cable (LAN).

Basically, of course, using cable to connect to the Internet desktop computers that do not have built-in Wi-Fi receiver. And if you buy a special computer adapter for Wi-Fi, then you can do without wires. I always advise to use a cable to configure the router and of course to upgrade the firmware. There are different cases, maybe Wi-Fi does not work on the laptop, and you need to connect to the Internet, or the speed of the wireless network is low, here we can use the network cable. The cable connection is always more stable than the air.

All we need is the network cable itself, which we will use to connect the computer to the router. This is a normal twisted pair, with RJ-45 connectors on both sides. Such a cable should be included with your router. It is true, it is short (depends on the manufacturer of the router). If you need a long cable, you can have one made at a computer store. You can do it yourself, but it needs a special tool. There are plenty of instructions on the internet.

Generally, you can connect 4 devices to your router with a network cable. It is 4 LAN ports you are likely to find on your router. In some cases, the LAN connector can be 1, or 8. It does not matter what version of Windows you have on your computer. The instructions are suitable for Windows 7, Windows 8, and Windows 10. In Windows XP you connect in exactly the same way but the IP settings will be slightly different.

Connecting to a router with a network cable (LAN)

It is very simple. Take a network cable, one end connect to the router to one of the LAN sockets (they are labeled LAN, or Home Network). And the second end of the cable into the network card on your computer. It looks like this:

If you connect a laptop to the router, then there we do everything exactly the same. One end of the cable to the router and the other end to the laptop network card:

That’s the connection. If the router is on, then the computer must immediately respond to the connection to the router. The connection status in the tray (lower right corner) will change.

If the router is connected to the Internet and is already configured, the connection icon is likely to be like this:

This means that all is well and the Internet is working.

If the router is not configured (you are going to configure it), or if there are some problems in the computer settings, the connection status will be a yellow exclamation mark. And without access to the Internet. Internet on the computer will not work.

If the Internet from this router works fine on other devices, but on the computer that we connected without access to the Internet, then you need to check the IP and DNS settings to connect to the local network.

Without access to the internet when connected via cable

It may be that once connected, the Internet will not work. The connection will be “no internet access,” or “Limited” (in Windows 8 and Windows 10). If the problem is not in the router (it distributes the Internet), then you need to check the settings on the computer itself.

Right-click on the connection icon and select Network and Sharing Center. In the new window, select Change adapter settings.

Next, right-click on the adapter Local Area Connection, or Ethernet, and choose Properties.

And set everything as in the screenshot below. Set it to obtain IP and DNS addresses automatically.

After that, reboot your computer, everything should work.

What to do if your computer doesn’t respond to a network cable connection?

It may be that after connecting the cable to the computer, the connection status will not change, and there will be a computer with a red cross (no connection).

In this case, try the following:

How to Connect to a Wired Network // Learn Windows //

  • Plug the network cable into a different LAN socket on the router.
  • If possible, replace the network cable. It is possible that the problem is in the cable.
  • Install or update the network card driver.
  • Go into adapter management, and make sure the adapter is enabled Local Area Connection. Right click on it, and choose turn it on.

As practice shows, everything works on the cable immediately after connecting. Without any problems and configurations. If you can not connect your computer to the router, then describe the problem in the Комментарии и мнения владельцев. Be sure to answer, and help with advice.

Using a bridge

There is another way to connect one cable to two computers. An example of the same, we have a computer that is already connected to the Internet. It doesn’t matter if you are using a router or if you are using a cable from your ISP directly to your NIC. If this PC has a second network card, it is possible to plug the second computer and distribute the Internet to it.

  • First, we connect the second computer via cable.
  • Next, you need to create a network bridge. to do this, press the “Win” and “R” buttons in Windows. Then type the command:
  • Now you need to see all of your physical and virtual network connections. If you are connected to the internet via a router, then choose that connection. If the cable is connected directly to the computer, then choose the Connect that was created before (PPPoE, VPN, etc).д.). Hold down the “Ctrl” button and select the connection and the second NIC, to which the second computer is connected. Next, right-click and select “Bridge Setup”.

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

  • There is no Wi-Fi module in the PC;
  • The network adapter is broken;
  • when configuring the router;
  • when updating the firmware;
  • When Wi-Fi connection speed is not fast enough.

Speed may be insufficient, for example, if you process video via local network, work with files from network storage. A Wi-Fi network can be loaded with the work of a wireless video surveillance system. If the PC or laptop is close to the router and the Wi-Fi network is actively used by other devices or users, a wired connection will be a good solution.

Before you can connect your computer to the Internet through your router via cable, you will need the following things:

It is worth pointing out that most modern computers already have built-in cards, as well as in laptops, but if the procedure is to be done with an old sample, you will need to buy a new card.

connect, your, computer, router, cable

It is best to take a cord cat5e, which is crimped on both sides. It usually comes with the router and is more than 1.5 meters long. The cable is suitable if the router will be located at the PC. In other situations, you will need to calculate the required length of wire and buy a new cord.

If a network cable comes with your router, the instructions for the explorer may be helpful. You need to act according to it.

How to connect computer to router via network cable (LAN)?

As a rule most of the problems occur when connecting to a router via wireless network. And connecting via network cable shouldn’t cause any problems. But, I already met some similar questions and decided to write a short instruction with photos, in which I will tell about how to connect computer (or notebook) to router via LAN cable.

And what is there actually to write about, took the cable, connect to the router, then to your computer, and you’re ready to go. But maybe someone could use it. As a rule, modern routers have 4 LAN connectors. This means that you can connect up to 4 devices through a network cable. And they will all get internet from the router, or work on the LAN. By the way, to set up a local network read this article.

  • Router with a free LAN socket (it is yellow).
  • Network Cable. A small cable comes with the router. But if you need a longer cable, you can make it yourself. I wrote about how to do this in the article How to make (crimp) a crossover. Or just go to a computer store and ask for a crimped network cable of the length you need.
  • A computer with a network card (this is usually built into the motherboard). Well, or a laptop, netbook with a RJ-45 network connector.

Take our power cable, it looks like this (you might have a slightly different, I mean different length):

Connect computer to router with ethernet cable

Plug one end of the cable into the yellow connector (LAN) of our router.

It does not matter which of the four connectors you plug the cable into.

Now connect the other end of the cable to our computer, or laptop.

This is what the network connector looks like on your computer:

Once the network cable is connected, one of the four lights on the router should light up, indicating that you are connected to the LAN connector.

Now we look at the computer screen. If on the notification panel (bottom, right) you see the following connection status (as in the screenshot below). All is well. Internet is already working.

But in this seemingly simple way, problems can also arise. Now we will take a look at some of the most popular ones.

Setting up static and dynamic connections

There are two options for network card settings: dynamic or static.

Static connection. with this connection your ISP will give you fixed settings. That is, your IP address will never change, it is usually prescribed in the contract. In the World Wide Web, the IP (external) will also be the same all the time.

Dynamic connection. this is the opposite of a static connection. With this method the IP address will be constantly changing after each reconnection to the provider. For example: switch off the router and then switch it on, the IP address will change.

How to configure a static connection

To create this connection, you need to make certain steps.

  • Click on the Network icon and select “Control Center. Then, in the window that appears, click on the “Change adapter parameters” on the left-hand side.
  • This will open a window with available adapters on this computer. Right-click on the icon “Ethernet”, “Properties”.
  • Click once on the section “IP version 4”, after highlighting this item click “Properties”.
  • In the window that appears, put a dot “Use the following IP address”, “Use the following DNS address.
  • Next, take these settings from the provider and enter in the sections. Click on “OK”

That’s all, you have set up a static connection.

How to create a dynamic connection

  • To create this type of connection we also need to log in to the network card. To do this, follow the same steps as for creating a static connection. See points 1, 2, 3.
  • Once you are in the “IP properties version 4 (TCP/IPv4)” section, select the checkboxes “Get IP address automatically”, “Get DNS server address automatically”. Click “OK” to finish installation.

Setting up the OS

To connect the laptop to the computer correctly, it is necessary to do, that these devices have different names, different ip-addresses and one workgroup.

To change the computer and workgroup name, go to “Start” and right-click on “Computer”. From the menu that will be displayed select “Properties”

In the window on the left select “Advanced system settings”. :

In the window that will open in the tab “Computer Name” click on the “Change” :

If necessary, change the computer name and the workgroup:

Now let’s deal with ip-addresses and other network settings. Everything I am going to describe must be done on both a computer and a laptop.

Right-click on the network status icon (near the clock) and select “Network and Sharing Center”.

Next, select “Change Adapter Settings” in the left column of the window that opens :

Find our local network connection and right-click on it, then select “Properties”.

In the list we look for the component “Internet Protocol version 4”. Highlight it and click on the “Properties” button

We put the switch to “Use the following IP address” and enter the IP address. And the subnet mask is This is what we enter for the computer:

connect, your, computer, router, cable

For a laptop just put a slightly different address: The subnet mask remains the same:

Connecting the cable to the laptop

It remains only to connect the second side of the same cable to the laptop, finding the appropriate port on the sidebar. It is not difficult to find it, because it has a different form. When connected, you will also hear a click. If the plug is protected by a blindfold, remove it carefully before making the connection.

A successful connection will be notified by an appropriate LED in the taskbar of the operating system. If the router has already been configured, access to the network will appear immediately, otherwise an Unidentified network or Connected, no access to the network notice will pop up.


You can only connect devices to each other if they are connected to the mains. We won’t talk about connecting to the internet in this article, but the illustration shows which socket to plug the WAN cable into.
