How to set up wired Internet. How to independently connect cable Internet to a computer or laptop

Today, connecting via Ethernet can be called the only technology that is potentially ready for the fairly rapid development of any type of service or application. Of course, the best is the enemy of the good, but people are so keen on making their Internet connection more reliable, faster and cheaper that sometimes it seems that this is not the case. Thus, recently it has appeared and began to become widespread new technology- More and more people prefer to use an Ethernet connection instead of traditional connection options.

Everything new is long forgotten old

It is worth noting that this technology has been quite actively used before, but only recently have experts begun to consider it as a full-fledged analogue of existing connection options - initially as equivalent, and over time as the most promising among all existing approaches to access network design. According to experts Cisco Systems, whose equipment is actively used today by almost all leading Internet service providers, the main advantage of this technology is that it is used not only to provide access to the Internet, but also to provide a number of other services, including voice transmission, building corporate networks and many others. At the same time, the cost of this solution, if we consider it from an operational point of view, in the vast majority of cases turns out to be lower compared to the use of traditional technologies, such as ATM/FR or SDH.

Introduction

In parallel with the growing competition between alternative and traditional operators in the field of local communication lines, these same operators are beginning to optimize own networks in order to provide more favorable price providing its services to the end user. In the vast majority of cases, a single package is used, which includes the transmission of data, voice, multimedia, as well as providing full Internet access.

Ethernet providers can also attract new customers with future-proof solutions using different network architectures that can accommodate the rapid growth of bandwidth-intensive applications, including IP video surveillance, as well as a variety of multimedia applications. .

DSL and its fall

This year, a real breakthrough in the field of broadband access began to occur in Europe, and many operators began to actively offer their DSL services, and some of them completely demonopolized their subscriber channels in order to provide access to many other alternative operators. Modern operators cable television began rolling out to provide combined Internet and cable TV services to their customers, and governments almost immediately began auctioning licenses to provide broadband FWA.

Ethernet - a universal solution

As the euphoria surrounding DSL technology, as well as the use of cable modems to provide broadband access, gradually faded, attention turned to the operational, technical, organizational and legal problems related to these services. In order to meet the ever-increasing demand for higher and higher bandwidth, both ISPs and equipment suppliers have increasingly begun to consider alternative option broadband access - connection via Ethernet using fiber optic cable.

What is Ethernet?

The solution to the problem is to broadcast speech, images and various data over an extremely simple, but at the same time relatively inexpensive Ethernet network. The unique advantage of this solution is that its use with fiber optic as a broadcast medium allows you to achieve gigabit access through the network directly from the premises of the clients themselves.

How are such networks connected?

In modern megacities there is large number buildings that are extremely attractive to network service providers are commercial business parks, office complexes, apartment buildings, universities and many other similar objects. To provide a new Internet connection through a router using Ethernet, network service providers use specialized dark fiber optics. Among the main advantages that distinguish this technology, it is worth highlighting the maximum possible speed and network distance - up to 100 km without the use of any intermediate amplifiers or regeneration. It should be noted that such an Internet connection via a router using Ethernet implies potentially unlimited bandwidth, and this is already very, very tempting for providers.

What are its advantages?

Gigabit Ethernet is very, very relevant, because it is an almost ideal performance-to-price ratio, representing an almost ideal choice for backbone applications not only in some individual corporate networks, but also for building full-fledged operator networks. A fairly good solution for wiring inside a certain building is multimode or single-mode optical fiber, which also belongs to the fifth category. Originally designed to provide Ethernet connectivity to local computers, it has ultimately become one of the most cost-effective networks available while still delivering extremely high throughput, especially when compared to DSL and various wireless and cable modems. .

The typical architecture that is used in the networks of modern providers is the implementation at the first stage of 10-megabit or 100-megabit Ethernet channels, which are carried out to separate rooms or apartments of a certain building, and are connected to the serving building using a specialized switch from Cisco Catalyst. In order to provide a connection to USB via Ethernet or the MAN city network, a full gigabit or even multi-gigabit Ethernet connection is formed. Aggregation of the schedule of various ring metropolitan networks is carried out using a third-level switch.

A service provider that is committed to providing broadband access may provide Internet connections to its customers, either directly to individual users or to entire small businesses. By providing Internet provider services within the city, the company can also offer new comprehensive services having added value. In order to ensure maximum efficient use ETTN network, the service provider must ensure that subscribers spend the maximum possible amount of time and money on the internal network instead of consuming resources to access global resources.

How to connect?

In order to provide an Internet connection via a cable using Ethernet technology, you need to have a specialized network card, a cable, as well as the network itself to which the connection will be made. It is worth noting that different networks can be configured to different speeds, so you should make sure that your network card is compatible with the network you will be connecting to.

Instructions

It’s worth noting right away that no one connects to the Internet via a phone using Ethernet technology. The connection itself is carried out as follows:

1. Go to the "Devices" tab.
2. Click the “Create” button, which is located on the toolbar.
3. We select “Ethernet Connection” from the options available to us (the options are located in the “Connection Type” list), and then click the “Forward” button.
4. If your card is already in the equipment list, then you need to select it from the list under the “Ethernet Card” heading. If she is not in this list, then in this case you need to select the “Other Ethernet card” item in order to use the equipment available to you. It is immediately worth noting the fact that the installation utility completely independently determines whether the Ethernet devices it supports are connected, and therefore offers you to configure them. If the configuration was carried out by you during the installation process, then the devices will be shown in the list in the “Equipment” tab.
5. If the “Other Ethernet card” option was selected, then a window with the contents “Select an adapter” will appear. In this window, you will need to select the manufacturer, as well as the model of your board and the name of the device itself. If you are installing the first such board in your computer, then you can select eth0 as the name, and then simply change the number with each new board. In addition, the Network Setup program will also allow you to carefully adjust the resources of your network card. After completing all procedures, click “Forward”.
6. In the “network” window, you will need to choose between a static IP address and DHCP. If your device receives different IP addresses, you do not need to specify the host name each time you connect to the network. Click “Forward” again.
7. Now click “Apply” and use the Internet.

Note

Now you can add various functions, such as connecting to a computer via the Internet or any others that you need. After you add a device, you can independently change the settings for its operation - just select the device from the resulting list, and then click “Change” on it. For example, after adding a device, it will completely automatically start working at boot time, but if you want to change this behavior of your equipment, you will need to go to its settings and change the value in the “Activate device when computer starts” section. You can also configure the printer connection via Ethernet.

It is worth noting that after adding the device does not turn on, to activate it, you will need to select it from the list, and then press the “Activate” button. If your system is designed to automatically turn on when the computer starts, then you should not repeat this step.

How to set up internet on windows 7

Today, the Windows 7 operating system is used by more and more users. Compared to Windows XP, the seven is not much different and, in principle, if you know XP well, you can work in the new Windows 7 without any problems. But still, despite the fact that this OS is very similar to Windows XP, there are still some differences in it. In today's article we will look at setting up an Internet connection in Windows 7 and using an example with screenshots we will learn how to set up the Internet on this system.

Instructions for setting up the Internet in the Windows 7 operating system

Before you start setting up an Internet connection, you need to install drivers for your modem, network card or other device with which you access the Internet. And only after the drivers necessary equipment will be installed, you can proceed directly to setting up your Internet connection. First you need to launch the Control Panel, to do this you need to click the Start button and select Control Panel:

You will see the Computer Settings window, in which you need to switch the view by category:

After that, in the list that appears, select “Network and Sharing Center”:

In the “Network and Sharing Center” you need to select the “Set up a new connection or network” item:

On next stage installation you need to be careful! Here the operating system prompts us to select an Internet connection option. In case you use ADSL connection, then you need to select the first item: “Connect to the Internet.” If you use, for example, 3G Internet, then you need to select the item “Set up a telephone connection.” Select the option you need and click “Next.” I chose the first option:

In the next window we just need to click on “High-speed (with PPPoE)” (If you are setting up 3G Internet, then at this stage you will see a modem selection window):

After this, you need to enter information from your Internet service provider. Here we write the username and password. If you are setting up 3G Internet, then you will have another additional field “Dialed number”. After the data has been entered, click the connect button:

If everything is configured correctly, you will see the message: “The Internet connection is ready to use”:

The next step internet settings on windows 7 will create a connection shortcut on the desktop. To do this, again go to the control panel -> Network and Sharing Center and click on the item “Change adapter settings”:

In the window that appears, right-click on the created connection and select “Create shortcut”:

Now click on the “Yes” button, thereby confirming the placement of the shortcut on the desktop:

How to change network card settings in Windows 7

As you all know, an Internet cable today is most often connected to a network card. The fact is that sometimes in order to properly configure the connection, it is necessary not only to install drivers but also to correctly configure the network card itself. To do this, you need to click on the “Change adapter settings” item in the “Network and Sharing Center” and in the window that opens, find “Local Area Connection.” On this connection, right-click to open the menu and select “Properties”, you have The following window will open:

Here you need to highlight Internet Protocol version 4 (TCP/IPv4) and click the properties button. A window will open in which you can enter the IP address, subnet mask, default gateway and other settings.

Possible problems when setting up the Internet on the Windows 7 operating system

If you did everything correctly but for some reason the Internet does not work on Windows 7, then you should check the following:

• Hardware drivers. Once again, you need to check that the installed hardware drivers are correct.
• Firewall settings (often included with antivirus programs). The fact is that when you create a new Internet connection, the firewall installed on your computer recognizes it as a new network and can block it. Therefore, you need to check your firewall settings and change them if necessary.
• It is also a good idea to check your computer for viruses. The most effective way would be to check your PC using 2-3 of the most popular anti-virus programs.
• If none of the above points gave positive result, then you can repeat all the steps of setting up the Internet again.
• Check the functionality of the equipment (modem, network card) on another computer or another operating system.
• You can study the article on how to set up the Internet on Windows XP. This article is located

A laptop is often used as a home computer, resulting in the problem of accessing inexpensive Internet, which in addition has high speed, is relevant for him. These qualities today are more closely matched by an Ethernet connection, so below we will tell you how to make correct settings Internet on a laptop.

Ways to connect a laptop to the Internet

There are several ways to connect your laptop to wired Internet:

• via a USB modem, which is convenient, for example, in the country, but such a connection often does not provide sufficient speed and usually costs more;
• using Wi-Fi if there is an access point, for example, when a Wi-Fi router can be connected to a desktop computer with the Internet;
• This can be done via a wired Ethernet network, which provides the highest speed, connection to which will be discussed later.

Cable Internet for a laptop is the fastest, but also the most inconvenient, since in fact it can make mobile computer stationary. At the dacha, for example, it is better to turn on a simple USB modem. A Wi-Fi router is very useful for use in an apartment.

Preparing for cable internet connection

To set up an Ethernet connection, first connect the network cable to your laptop. You can also connect a router to it, which, after configuration, will be able to distribute Wi-Fi to any other devices, providing fairly decent speed.

The twisted pair wire is laid from the switch in the entrance to the place where you plan to make an access point to the Network. Using a special tool, a plug with an RJ-45 connector is mounted on the cable, which must be plugged into the corresponding socket on the panel on the side of your laptop.

Connecting to the Network will not be possible without the necessary drivers for the network card. To check that they are installed correctly, do the following:

1. Windows XP. Go to the control panel by clicking “Start”, select the network connections section.
2. For Windows 7 and older versions. Go from the control window to the network settings section and public access, then select the option to change settings for the adapter.

If the window that opens is empty, the driver is probably not installed.

General rules for connecting high-speed Internet

The data required for connection is specified in a special agreement. If you want to turn on the router, you will need to make other settings described in the specifications for the device. If automatic network detection does not occur, you will have to configure the TCP/IP protocol yourself.

In Windows 7 and 8, the connection is made in the following order:

In Windows 10, the connection is made as follows:

1. From the Settings section of the Start menu, go to Network and Internet.
2. Next, you will need to open the adapter settings settings.
3. Next, follow all steps, starting from 3, described for Windows 7 and 8 systems.

No further actions are required - the connection should work at full speed automatically. If you connect via a router, the procedure may vary for different providers, so to set up the Internet, first find out the full information on the corporate website of the provider providing this service.

Alternative Internet for a summer residence

Please note that in a dacha where it is not possible to connect to the Internet via cable, optimal choice will use a USB modem. As a rule, there are no problems with its connection:

1. Insert a SIM card into the modem, then connect the device to the laptop;
2. The system will detect a new device and offer to install a program that allows you to use a modem on your device;
3. You may then have to enter the PIN code indicated on the card, after which the modem will automatically connect the laptop to the Internet.

In a word, you can connect to the Internet, which would have high speed even in the country, through a cable or router, and the procedure for setting up the connection can sometimes differ slightly.
