How to set up the Internet through an Internet router: tips and tricks. Setting up a router: detailed instructions for dummies Connecting the router to the network

Many articles have already been written on the topic of connecting to the Internet via a wireless network. Instructions for connecting, solving various problems, errors, etc. And in this article we will look at connecting a router to a computer using network cable, which usually comes with the router. With a cable connection, everything is much simpler than with Wi-Fi. But despite this, sometimes problems arise with connecting to the router using a network cable (LAN).

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

All we need is the network cable itself, which we will use to connect the computer to the router. This is normal twisted pair, with RJ-45 connectors on both sides. This cable should be included with your router. True, it's short there (depending on the router manufacturer). If you need a long cable, a computer store can make one for you. You can do it yourself, but you need a special tool. There are plenty of instructions on the Internet.

As a rule, you can connect 4 devices to the router via a network cable. You will most likely find 4 LAN connectors on your router. In some cases, the LAN connector can be 1 or 8. It doesn’t matter which Windows version installed on your computer. The instructions are suitable for Windows 7, Windows 8, and Windows 10. In Windows XP, everything is connected in exactly the same way, but the IP settings will be slightly different.

Connecting to a router using a network cable (LAN)

Everything is very simple. We take a network cable, connect one end to the router into one of the LAN connectors (they are signed LAN, or Home Network). And we connect the second end of the cable to the computer’s network card. It looks like this:

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

That's all the connection is. If the router is turned on, the computer should immediately respond to connecting to the router. The connection status in the tray will change (bottom right corner).

If the Internet is connected to the router and it is already configured, then most likely the connection icon will look like this:

This means that everything is fine and the Internet is already working.

And if the router is not yet configured (you're just about to set it up), or there are some problems in the computer settings, then the connection status will be yellow exclamation point. And without internet access. The 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 we need to check the IP and DNS settings for connecting via the local network.

Without access to the Internet when connected via cable

It may be that after connecting the Internet will not work. The connection will be “without Internet access”, or “Limited” (in Windows 8 and Windows 10). If the problem is not with the router (he distributes the Internet), then you need to check the settings on the computer itself.

Click right click mouse on the connection icon and select Network Control Center and shared access . In the new window select Change adapter settings.

And we set everything up as in the screenshot below. You need to set automatic acquisition of IP and DNS addresses.

After that, restart your computer, everything should work.

What to do if the computer does not respond to connecting the network cable?

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:

Connect the network cable on the router to another LAN connector.
If possible, replace the network cable. It is possible that the problem is in the cable.
Install or update the network card driver.
Go to adapter management and check if the Local Area Connection adapter is enabled. Right-click on it and select enable.
If the Internet via cable does not work on a computer with Windows 10, then see this article.

As practice shows, everything works via cable immediately after connection. Without any problems or settings. If you are unable to connect your computer to the router, then describe the problem in the comments. I will definitely answer and help with advice.

As a rule, most problems arise when connecting to the router via a wireless network. Connecting via a network cable should not cause any difficulties. But, I have already encountered similar questions several times, and I decided to write a short instruction with a photo, in which I will tell you how to use LAN cable connect your computer (or laptop) to the router.

And what exactly is there to write about here? We took the cable, connected it to the router, then to the computer, and everything was ready. But still, it might be useful to someone. As a rule, modern routers have 4 LAN connectors. This means that you can connect 4 devices using a network cable. And they will all receive the Internet from the router, or work on the local network. By the way, read the article on setting up a local network.

We will need:

Router with a free LAN connector (yellow).
Network cable. A small cable is included with the router. But, if you need a longer cable, you can make it yourself. I wrote how to do this in the article. Or just go to a computer store and ask to crimp the network cable to the length you need.
Computer with network card (usually it is integrated into the motherboard). Well, or a laptop, netbook with an RJ-45 network connector.

Let's get started :)

Take our network cable, it looks like this (yours may be slightly different, I will enter a different length):

We connect one end of the cable to the yellow connector (LAN) of our router.

It doesn't matter which of the four connectors you connect the cable to.

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

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

After connecting the network cable, one of the four indicators on the router should light up, indicating a connection to the LAN connector.

Now look at the computer screen. If in the notification panel (bottom, right) you see this connection status (as in the screenshot below), then everything is fine. The Internet is already working.

But, in this way, it would seem in a simple way, problems may also arise. Now we will look at some of the most popular ones.

Problems connecting your computer to the router via a network cable

After connecting, the status on the notification panel may not change; you will see the computer crossed out with a red cross.

In this case, first of all you need to check the cable with which you connected the computer to the router. How to do it? You can, for example, take another cable, or a cable that carries the Internet directly to your computer. If this connection status changes (even if a yellow triangle appears), then the problem is in the cable. Perhaps something has come loose there. Just change it.

It's possible that LAN card just disabled. Let's check. Go to and find there LAN connection. If there is a status next to it Disabled, then right-click on this connection and select Turn on.

If such a connection as There is no local network connection at all, then most likely the driver is simply not installed on your network card. Download and install the driver. If there was a disc included with your computer (laptop), then most likely it has this driver.

Connected the cable, but the connection does not have access to the Internet

And this can happen. The problem looks like this:

First, you need to determine what the problem is. This may occur due to problems on the router side. See the article on this issue.

But I'll tell you in a simple way. If other devices work normally from this router, and there is Internet on them, then most likely the problem is on the computer itself. It's clear:).

And as a rule, there is only one problem.

Go to again Control Panel\Network and Internet\Network Connections and right-click on Local Area Connection. Select properties. Then highlight "Internet Protocol Version 4 (TCP/IPv4)" and press the button again Properties.

Set to receive IP and DNS automatically and click OK.

This should help.

But, we must not forget that, for example, there may be technical problems with the network card (maybe it just burned out) and other various reasons why a variety of problems may arise.

Here are the instructions, everything seems simple, but it turned out to be not very small. I hope it is useful to someone.

The moment another computer or laptop appears in the house, the question arises of how to organize Internet access for all devices. The way out of this situation is simple - (or as it is also called, a router). But due to ignorance of the basics of building local networks, connecting a router can be far from the easiest task. In this article we will talk about how to quickly and easily connect a router to a computer or laptop.

In order not to create unnecessary problems, you need to clearly understand what tasks it performs. The router creates an internal home local network and connects it to the Internet. Once you have installed and connected the router, it becomes an access point, DNS and DHCP server. Simply put, it becomes the center of your home local network, and now all connections to the Internet occur exclusively through it.

The picture shows rear end modern router. Let's look at all the elements that are placed there in order.

Power connector. You need to connect the power cable to this connector.
Reset button. This button resets all router settings to default. This can be useful when reconfiguring the router or if you have lost your access password.
Connector for USB devices. Connect here:
1. Printers;
2. Hard disks;
3. Flash drives;
4. Other devices compatible with the router;
Network connector for connecting to the Internet. You need to connect a cable from your Internet provider to this connector. Depending on the model of your router, this connector may look different. But he always:
1. highlighted in a different color than other network connectors;
2. located at a distance from other network connectors;
3. signed as “WAN” or “Internet”;
Network connectors for connecting other devices to the router. As a rule, these connectors are highlighted in one color and grouped into a separate group. Home routers use four of these network connectors. Using these connectors you can connect:
1. Desktop computers;
2. Laptops;
3. Media players;
4. TVs;
5. Switches (switch);
Antenna for . The number of antennas may vary, depending on in this case there are three of them. WITH using Wi-Fi connections you can give access to the Internet to such devices as:
1. Smartphones;
2. Cell phones;
3. Laptops;
4. Desktop computers;
5. Media players;
6. Any other Wi-Fi enabled devices;

Practical part

So, now that we have understood the main functions and connectors of the router, we can begin connecting it. In order to connect you need to do the following:

Connect the router to power.
Connect the network cable from the Internet to the “WAN” connector, which is located on the back of the router.
Connect the router to your computer or laptop using a network cable. For this you will need a small one. As a rule, such a cable comes with the router. Plug this cable into the network connector on your computer, as well as into one of the ports on the back of the router.

All after these simple steps the local network must earn. In order for the Internet to work on your computer, you may need to make some adjustments to your router. For example, copy from a computer. To access , open your browser and enter the address "http://192.168.0.1" (or "http://192.168.1.1" if the first option does not work). This address will open the router’s web interface, where you can configure all its parameters.

Today, perhaps, you will no longer meet a person who does not use a computer or does not have a PC at home. Besides, everything more services, programs necessary for work and leisure, work when connected to the internet.

Also, recently the situation has become increasingly popular when an apartment, house or office has not one device, but several (PCs, tablets, communicators, smartphones, etc.), each of which requires its own separate connection to the network.

The ability to connect several devices to the internet, while having one input signal point from the provider, is currently achieved using a router or router.

The router itself is network device, the purpose of which is to transmit packet data between devices paired with it and the access point - the service provider. In addition, more expensive routers are equipped with a number of additional functions, among which:

the ability to set restrictions on access to sites that are potentially dangerous for software;
ability to connect a firewall;
the ability to encrypt network access and traffic distribution;
ordered distribution of traffic across access points, etc.

A standard router, which can often be found both in a private home and in a company office, public places, is a small-sized equipment consisting of a hardware unit, an antenna for transmitting a Wi-Fi signal, a power supply for connecting to the mains, patch cords (patch cords).

Photo – Equipment and connection of the router

A standard router is capable of organizing a network by connecting 4 PCs via wired communication, as well as 5-10 devices for which channels will be allocated Wi-Fi signals. However, experts do not recommend completely loading the router, especially if it is not an expensive model of this device. Otherwise, the router may freeze and cannot withstand heavy loads.

Some router models may be equipped with USB ports to connect a flash drive to them or hard drive. This feature will allow you to use the equipment as file server, print server, etc. In addition, some models also boast support for 3G modems.

What you should pay attention to

When choosing a router, you should consider the following features and operating parameters of this equipment:

for organization home connection or a network for a small office, a regular (non-professional) router from the mid-price range will be sufficient;
device support for IEEE 802.11g and IEEE 802.11n standards is required will provide data transfer speeds via Wi-Fi up to 600 Mbit/s;
installation must support PPTP or L2TP, which will provide access to Internet communications from almost any provider.

How a wireless Wi-Fi router works

The principle of operation of the equipment is based on receiving and converting the recipient's address, which is “written” in the header of the information packet for its transmission, then the path along which the information is addressed is determined using the routing table. If the routing table does not provide any address, the information is not accepted and discarded.

Photo - Example of a user network working with a router

In practice, there are some other systems for transmitting data to devices paired with the router. For example, the use of the sender address or upper-level header protocols. There are also cases when the router’s operation is based on the transmission of addresses of both the sender and the recipient, as well as filtering the transit stream of transmitted data.

How to install a Wi-Fi router: step-by-step instructions

In order to connect and configure the router yourself, you need to do the following:

The first thing they do to install the equipment is to connect all communications from the router to the PC and to the Internet signal transmission unit from the provider. To do this, insert an Internet cable into the connector called WAN, and insert the cable that comes with the router into one of the remaining ports; its other end is intended for the Ethernet connector on the back panel of the PC. After this, turn on the power to the device.
Next move on to configuration software router. The equipment setup is not standard and may differ depending on the router model and connection settings from the provider. Configuration can be done through any browser installed on your computer ( Google Chrome,Opera, Internet Explorer, etc.). To do this, you need to log into the administrative interface of the device by entering address bar Browser combination of numbers: 192.168.1.1. After pressing the Enter key, the equipment administration window should pop up. If this does not happen, then you should check the cable connection, make sure that the connection is running, and then try again.
The next step is directly Wi-Fi setup connections. If the router is equipped with a function quick setup, then you need to start the “Quick Setup” service and follow the prompts of the installation wizard. Among the setup steps there will be a selection of the following parameters: - type of preferred connection;
— type of Internet connection;
Next, you need to connect the Wi-Fi module itself directly. To do this, the installation wizard offers the following menu.

After these steps, the Internet connection should already be working. However, if the Internet speed is low or constant signal loss occurs, experts recommend choosing a specific channel (from 1 to 13), saving the settings. It is also worth taking care of the access password to the signal of the connected router. Otherwise, unauthorized connections are possible, which will also reduce traffic and make the router work slower.

After the router is connected and configured, all that remains is to connect the network card to your PC or laptop and use the device’s internet connection. On a laptop, you need to make sure that a special key is pressed that turns on Wi-Fi mode. If this operation is completed, you must connect the device to the network.

To do this, right-click on the network icon on the desktop toolbar and select the name from the menu that opens. established network, click the “Connect” button.

The connection is made in a similar way for Windows 8; for other systems, the device is put into operation according to a similar scheme.

How much does a router for a computer cost?

Today, the electronics and computer equipment market offers its customers a wide selection of routers, which differ from each other both in the manufacturer and in some of the functional features of the device. These could be routers for home network with a few connected devices or industrial equipment to provide access to the Internet for public places and large offices. Accordingly, considering functionality device, the cost of devices will vary significantly. By visiting a store or online store of electrical goods, the client can choose the appropriate equipment that will meet the requirements for it. At the same time, he will need to deposit an amount of money ranging from 1 thousand rubles. for a standard model up to more than 25 thousand rubles. for professional multifunctional devices.

Almost all modern gadgets can be connected to wifi networks. This makes it possible to use the convenience of the Internet at high speed almost everywhere. There is an opinion that this only applies small devices, such as a tablet, phone or laptop (printer, camera, etc.). Many users are interested in the question of how to connect a computer to wifi, is it difficult, and what devices may be needed for this.

A stationary computer is called stationary because it means connecting all communications to it through various wires to a “permanent place of residence.” The PC can be moved in the future to another location, but this requires a major revision of cable routes, location of sockets, etc.

A novelty in recent years has been the appearance wireless networks, thanks to which even a PC can be connected to the Internet via wifi technologies.

Below we will figure out what is needed for this, and in what order it is recommended to connect desktop computer to the Internet “wirelessly”.

The outline of the article will be like this:

Necessary equipment:

External wifi receivers;
Internal;
Router.

Installing devices on a computer and setting them up:

External receiver;
Interior;
Router.

Necessary equipment

Since a PC in most cases is deprived of the ability to find and connect to wireless networks, you must first take care of purchasing equipment that will give it such privileges. Let us consider in detail how it happens.

External wifi receivers

Such devices look very similar to a large flash drive: they are small gadgets with a USB plug at one end (see Fig. 1). In addition, they may have a small antenna to increase the “collected” signal.

Fig.1 External adapter (network card) Wifi from Tp-Link.

This device for connecting a PC to a wireless network is quite inexpensive (can be purchased for 10-20 USD). After purchasing, all you have to do is connect it to your computer via USB, install it from the included driver disk, make the simplest settings and connect to wifi. We will consider all these operations in detail after we get acquainted with another type of wireless network adapters.

Internal (built-in) wifi receivers

Their name comes from the fact that they are built inside system unit PC. To connect to the motherboard, they use the PCI interface, through which they are connected to a special connector.

rice. 2 Internal wifi receiver (adapter).

These devices differ little in price from external ones, and installing them on a computer also does not take much time and should not cause any particular difficulties.

So which type of adapter should you choose? External or internal?

The external one can be quickly disconnected and connected to another PC;
The internal receiver will not take up free place on the table; in addition, it is less susceptible to damage, since it cannot be touched by the user.

The choice is yours.

Router (router)

A wifi receiver can connect a computer to the network only if it can “reach” it. In other words, the signal source - the router - must be within range.

Fig.3 Router TP-LINK AC1750

It receives a signal from the provider via an Ethernet cable, passes it through itself and “distributes” it to wireless devices (including a computer). Routers are more versatile and easier to use than access points. They allow you to simultaneously connect several gadgets (laptop, tablet, smartphone, PC...) to one network.

Connecting equipment

We move on to the promised description of the process of installing a Wi-Fi receiver for a desktop computer.

External wireless network adapter - installation and configuration

As an example, let’s take the TP-LINK TL-WN721N receiver model, which has proven itself to be a reliable receiver. It can be purchased for 13-18 USD, and it is ideal for Windows 7. In addition, it supports all types of data encryption, and it is possible to quickly create a connection. The maximum signal reception speed is 150 Mbit/sec.

rice. 4 External wifi network card TP-LINK TL-WN721N.

Step 1

We take the device out of the box and carefully examine the package, which should include:

The receiver itself;
USB cable (can be connected through it and used as an extension cord when searching for a better signal);
Instructions in several languages;
Driver disk.

Step 2

We connect the adapter to the PC directly, or through an extension cord (it can strengthen the signal, acting as an additional antenna) to a USB port. Next, ignore any messages about the successful installation of device drivers. You need to install them yourself from a special disk that we found in the receiver box.

Step 3

Insert the driver disk into the computer, and then launch the installation wizard. In the program that opens, select our model and click “Install driver and utility” (see Fig. 5)

Fig.6 Dialog window of the installer program.

During the installation process, the following messages may appear (Fig. 7 and Fig. 8):

rice. 7 Notification on a 32-bit system that the utility cannot be installed. This is not scary, so feel free to click “Yes”.

rice. 8 System Windows security 7 may warn about an unknown driver manufacturer. This is also not critical, click “Install anyway...”

After a minute or two, the process will end, and you will find such an icon on the taskbar (see Fig. 9). It signals that the receiver is ready to connect the computer to wifi.

rice. 9 Icon indicating the presence of wireless networks within the range of the receiver.

Step 4

Now that the adapter is ready to connect the Internet to your computer, all you have to do is click on that icon and select the appropriate wifi network.

Fig.10 Selecting the desired network from the list of available connections.

And then enter the password (security key) and click OK.

All. Your computer is now connected to the network via an external wifi receiver. You can start using the Internet.

Now let's move on to the next chapter of the article.
