Internet is connected via wire. Types of wired Internet connection. Dynamic and static internet connection

There are two types of internet connection today. The first type is a wired connection that uses a cable called twisted pair to connect. The second type is a Wi-Fi connection that provides an Internet connection using radio waves. Wi-Fi connection has become widespread in our time. However wired Internet has a number of advantages that are relevant in large organizations and offices. At home, it also makes sense to make a wired connection to at least one computer. For a stable Internet connection and efficient operation, you must correctly configure its connection settings.

Benefits of a wired internet connection

Over the past 15 years, the Internet has rapidly penetrated into all spheres of our lives. It is necessary in banking, trade, manufacturing, and is also indispensable for the exchange of information and personal communication. The most common ways to connect to the global network today are a wired connection and a Wi-Fi connection.

For a wired connection, use optical cable or twisted pair. The first type of cable has a significant advantage, as it provides information transfer rates up to 1 GB per second. Over twisted pair, the speed limit reaches 100 MB per second.

The speed at which information is transmitted through a cable depends on its type and on the network card that receives the signal. This affects the operation of desktop computers, game consoles, TVs and other devices connected to the same network. Streaming information does not require constant exchange between devices, which significantly increases the processing speed. Speed in a local connection between workstations is of great importance when working in a corporate network. This is taken into account if there is a need to quickly transfer a large amount of information.

With a Wi-Fi connection, the connection to the Internet is carried out using radio waves operating in a certain range. Therefore, Wi-Fi is more in demand on household level. It is convenient because it allows you to immediately connect to the Internet from a smartphone, tablet or laptop anywhere where there is an access point. However, signal reception is affected by neighbor devices operating in the Wi-Fi connection frequency band and objects in the path of radio waves.

A Wi-Fi connection does not require cabling, but it is highly susceptible to radio interference, and the farther you are from the access point, the worse the signal reception

A wired connection has several advantages over wireless:

the speed of receiving and sending information with a wired connection is about 2 times higher than that of Wi-Fi;
when exchanging files with the server, the delay is minimal, which is important in online games that require maximum speed of actions from the user;
wired connection is more resistant to interference in the network; it is not affected by gadgets operating on the Wi-Fi frequency band or nearby sources of electromagnetic radiation;
the signal strength with a wired connection does not depend on obstacles in the path of passage and the influence of external factors.

Errors that occur when connecting a wired connection can be indicated by codes that indicate the cause of the problem.

How to connect a cable to a computer or laptop

Even an unprepared user can connect an Internet cable to the computer's network adapter connector on their own. For connection, a standard cable (twisted pair) with crimped RJ-45 connectors on both ends of the cable is used.

You can connect the cable as follows:

Prepare a network cable of the required length.
Connect one connector to any LAN port on the router.
First, connect the cable connector to any LAN connector on the router
Connect the other connector of the cable to the laptop or computer connector.
Now you need to connect the second cable connector to the computer's LAN connector
When using an older type of modem, connect the incoming ISP cable to the yellow Internet connector on the modem.
In old-style modems, the provider's cable should be connected to the yellow modem connector
Connect the connecting LAN cable to any Ethernet port of the modem and to the network port of the device.
The connecting cable from the device must be connected to the modem's Ethernet connector
After connecting the computer to the router, the indicator LED on the latter will light up, signaling the establishment of a connection between the devices.
When connected to a computer, the indicator LED on the indicator panel of the router will be lit

Connecting the cable is not a big problem, since all connectors have connectors that fit only into the corresponding sockets on the computer's connector panel. It is extremely difficult to make a mistake in this process even for a novice user.

Dynamic and static internet connection

After connecting the cable connectors and building a connection between network adapter computer and provider equipment, you can debug the Internet connection. First of all, you need to choose a way to connect to the backbone network, based on specific goals. There are 2 connection methods:

dynamic connection is a method in which an individual IP address assigned to a computer is configured automatically and changes when the initial settings are transformed. The equipment of the provider company independently assigns the values of the network address and the default gateway to the computer. When connecting a computer to a trunk line, the connection to the global network occurs immediately, without requiring additional input of identification data from the user. The only inconvenience with such a connection is the possible representation of a remote connection to your address. In this case, you must first connect to the trunk line directly, bypassing the router;
static connection is a connection method when the individual IP address provided to the computer remains constant and is indicated when concluding an agreement with the provider company. During such a connection, the user sets the address manually, and also independently prescribes the values \u200b\u200bof the main gateway and DNS servers. If such information is not in the contract, then you can find it in the technical support department of the provider company. Some ISPs may require you to enter a username and password for online licensing. This information, as a rule, is indicated in contractual documents or is determined by the subscriber independently.

How to create a dynamic connection

For right creation dynamic connection, you must perform a series of sequential steps:

From the Start key menu, navigate to Network Connections
In the "Settings" section that opens, in the "Change network settings" block, select "Configure adapter settings".
In "Options" go to the option "Configure adapter settings"
In the Network Connections console, right-click on an Ethernet connection.
Select "Properties" from the menu that opens.
Select "Properties" from the Ethernet connection drop-down menu
In the connection console, highlight the IP version 4 (TCP/IPv4) component and click Properties.
In the properties panel, select the line IP version 4 (TCP / IPv4), and then open "Properties"
In the TCP/IPv4 Protocol Attribute Console, check the "Obtain an IP address automatically" and "Obtain DNS server address automatically" radio buttons.
In the last step, activate the switches "Obtain an IP address automatically" and "Obtain DNS server address automatically"
Click OK to complete.

The dynamic connection is now ready to use.

How to create a static connection

To create a static connection, you need to follow these steps:

Everything, the static connection is established.

Currently, most home Internet subscribers use a dynamic connection, since the main method is to connect through a router. A static connection is used with a dial-up connection or a direct connection.

When using an ADSL modem connection, only static addresses assigned by the ISP are used.

How to set up an L2TP connection in Windows 10

The L2TP tunnel protocol used to connect to the global network is a symbiosis of the old PPTP protocols from Microsoft and L2F from Cisco. It is easily processed by network devices and has a high speed of information exchange due to reduced processor load. It has great connection stability and high security. Able to create tunnels to work in any networks. The L2TP protocol is usually used in corporate networks, as it allows you to create a network connection over an existing network. This provides a stable connection between the main office of the organization and regional offices.

To set up an L2TP connection, you need to perform a series of sequential steps:

Right-click on the "Start" icon.

The created L2TP connection increases the security level for the subscriber and makes more simple connection with provider equipment.

How to set up a PPPoE connection in Windows 10

The PPPoE Internet network connection protocol is used when connecting to the backbone network using Ethernet technology. This method has a number of advantages, for example, an extended range of additional features, data compression during transmission, and authentication and encryption operations with information packets. Connection requires authorization on the network (entering a username and password). Used for direct connection to the backbone network and provider equipment.

To connect to the Internet using the PPPoE protocol, you need to perform a number of operations:

Open the Network and Sharing Center.
Here select "Create and configure a new connection or network".
In the "Network and Sharing Center" section, click on "Create and configure a new connection or network"
In the "Set up a connection or network" console, select "Connect to the Internet" and click "Next".
Select the first item - "Connect to the Internet" and click "Next" for further settings
Select the High Speed (with PPPoE) tab.
In "Internet connection" select the connection "High speed (with PPPoE)"
Next, enter the login and password received from the provider, and click "Connect".
Enter the login and password received from the provider and click "Connect" to complete the setup

You now have a PPPoE connection established.

Giving permission to other users to use the connection is only worthwhile when installing home Internet, since the number of users is limited.

Ways to troubleshoot wired internet connection problems

When connecting a wired Internet, errors periodically occur due to hardware problems, a break in the backbone network, or incorrect user actions. In most cases, connection problems arise due to the careless actions of the user himself.. To determine and eliminate the cause of the problem, you need to perform simple steps according to the following algorithm:

Launch "Network and Sharing Center".
In the "Network Connections" tab, select "Troubleshooting".
Go to "Network and Sharing Center" and open the "Troubleshooting" section
Select Internet Connections.
For further settings, select the "Internet Connections" option
Next, click on the "Run the troubleshooter" line.
Wait for the problem detection process to complete
After the process is completed, in the window that appears, select the "Troubleshoot Internet Connection" tab.
Select "Troubleshoot Internet Connection" and wait for the diagnostic process to complete
At the end of the troubleshooting process, close the console if no problems are found. If problems are found, follow the further instructions in the pop-up windows.

Run the troubleshooter by clicking on the appropriate line

After the verification process is completed, in the Incoming Connections console, select Find this computer on the network and click Next.
Check the "Locate this computer on the network" box and continue troubleshooting with the "Next" button
The troubleshooter will check if the firewall is blocking this computer from the network.
Wait for the network gateway configuration check to complete
During the troubleshooting process, follow the instructions that appear on the console.
If no problems are found, close the console.
If problems are found, follow the program instructions to fix them.

This completes the check for incoming connections.

The following instructions show the detection of one incoming connection problem. More detailed information about the problem can be found by clicking on the "View additional information" line.

The above method for finding connection errors is a classic and was developed by Microsoft specialists. In reality, everything is much simpler, since the problem with the Internet connection can be caused by other reasons that are eliminated mechanically.

This algorithm helps to fix the problem with no internet connection in most cases:

Restart your computer.
Disconnect the router from the network and wait 10-15 seconds.
Turn on the router.
If the connection is not restored, click on the Reset button to reboot the router.

To avoid problems with your Internet connection, it is recommended to periodically disconnect the router from the network and give it time to recover.

Nowadays, all ISPs prefer to establish a dynamic connection to the backbone network. This is more convenient for the network subscriber and for the provider company, since it does not require reconfiguration of parameters in case of any changes in the network equipment. If you plan to often use remote access to your computer, then, of course, it is better to choose a direct connection, bypassing a router or modem. For home Internet, you can always change the router settings and the type of connection that were originally installed by the provider's specialists. In the future, when the system configuration is changed or a complete reinstallation, the network parameters are set automatically. With a direct connection, the settings will need to be set manually. All this must be taken into account by users when choosing the type of Internet connection.

Connecting a computer to the Internet via a modem, via a local network, via another computer and via a router, how to set up internet connection and setting up a network between computers.

Connecting two computers to the Internet

If you have different operating systems on your computers, Windows XP, 7 or even Windows 8, don't worry, they all work on the same principle over the network.

I tried to describe as lightly as possible how to set up a LAN connection and an Internet connection via a local network, if you are a beginner and have not understood this before, then I know for sure that you were satisfied. However, if you have any questions, please email me. [email protected] I will gladly help you.

8 comments to Connecting a computer to the Internet via a local network

Hello, I have the following problem. Netbook on windows xp is connected via wifi. It is also connected via local network to a computer with Windows 7. The network is configured correctly. I've looked all over the Internet, but I just can't allow a computer on Windows 7 to connect to the Internet via a local network from a netbook. How to do it,

After concluding an agreement with an Internet provider and installing cables, we often have to figure out how to connect to the network from Windows on our own. To an inexperienced user, this seems to be something complicated. In fact, no special knowledge is required. Below we will talk in detail about how to connect a computer running Windows XP to the Internet.

If you find yourself in the situation described above, then most likely in operating system connection parameters are not configured. Many providers provide their own DNS servers, IP addresses and VPN tunnels, the details of which (address, username and password) must be entered in the settings. In addition, connections are not always created automatically, sometimes they have to be created manually.

Step 1: New Connection Wizard

We open "Control Panel" and switch the view to classic.
Next, go to the section "Network connections".
Click on the menu item "File" and choose "New connection".
In the start window of the New Connection Wizard, click "Further".
Here we leave the selected item "Connect to the Internet".
Then choose manual connection. It is this method that allows you to enter data provided by the provider, such as a username and password.
Next, we again make a choice in favor of the connection that requests security data.
Enter the name of the provider. Here you can write whatever you want, there will be no mistakes. If you have multiple connections, it's best to enter something meaningful.
Next, we prescribe the data provided by the service provider.
We create a shortcut for connecting on the desktop for ease of use and click "Ready".

Step 2: DNS setup

By default, the OS is configured to automatically obtain IP and DNS addresses. If the Internet provider accesses the World Wide Web through its servers, then you need to register their data in the network settings. This information (addresses) can be found in the contract or by calling the support service.

Creating a VPN Tunnel

VPN is a virtual private network that works on the principle of "network on top of a network". VPN data is transmitted over an encrypted tunnel. As mentioned above, some providers provide Internet access through their VPN servers. Creating such a connection is a little different from the usual one.

In the Wizard, instead of connecting to the Internet, select the network connection on the desktop.
Next, switch to the parameter "Connecting to a virtual private network".
Then enter the name of the new connection.
Since we are connecting directly to the provider's server, there is no need to dial the number. Select the option shown in the figure.
In the next window, enter the data received from the provider. This can be either an IP address or a site name like "site.com".
As in the case of connecting to the Internet, check the box to create a shortcut, and click "Ready".
We register the username and password, which will also be given by the provider. You can configure saving data and disable their request.
The final setting is to disable mandatory encryption. Let's go to properties.
On the tab "Safety" remove the corresponding checkbox.

Most often, you don’t need to configure anything else, but sometimes you still need to register the DNS server address for this connection. How to do this, we have already said earlier.

Conclusion

As you can see, there is nothing supernatural in setting up an Internet connection on Windows XP. The main thing here is to follow the instructions exactly and not make mistakes when entering data received from the provider. Of course, you first need to figure out how the connection occurs. If this is direct access, then IP and DNS addresses are needed, and if it is a virtual private network, then the address of the host (VPN server) and, of course, in both cases, the username and password.

The article describes how to set up cable Internet on a computer.

A lot of users use Wifi at home to connect to the Internet, which is very convenient, especially if you have several devices (computer, tablet, smartphone). But it also happens that you need to connect your computer to the Internet directly via cable, without using a router. In this case, a direct connection is established between your ISP and the PC network card (Internet speed increases).

In addition, you may simply need to connect wired Internet to a new computer that you want to install at home. We will talk about all this in this review. All computers that are running " Windows» ( 7, 8, 8.1, 10 ) will be configured in the same way, the instructions below are suitable for all these cases.

To begin with, let's note some points. The Internet connection that providers provide to their users is usually divided into static and dynamic. A static connection is when you are given your permanent, unchanging IP address. A dynamic connection, on the other hand, automatically selects an IP for itself, which can change every time.

Many modern companies provide just such options when connecting to the Internet, but there are also providers that use a PPPoE connection that requires a password and login. The provider offers to establish such connections by sending its masters to clients. But this often happens long history, so we will learn how to connect cable Internet to a computer on our own.

Connecting the Internet to a computer via cable using static and dynamic IP

In order to connect an Internet cable to a computer, as you know, you need to plug it into the Ethernet port on the rear panel. This creates a direct connection from the ISP to the computer's network card. Next, you will need to configure the connection in the operating system.

To set up the Internet on your computer in this way, you need to take the following steps:

Through the menu Start" go to " Control Panel»
