Wired ethernet connection on a Lenovo laptop. Connecting a laptop to the Internet via cable. Setting up a laptop to connect to the Internet via cable

Currently, a laptop is present in almost every home, because it is the most convenient and practical type personal computers. However, sometimes users need to transfer files from laptop to laptop, and there may not be suitable media at hand. In this case the best solution there will be a connection between two laptops via local network, and in this article we will look at everything possible ways connecting mobile PCs.

So, there are two most common ways to connect and/or exchange information between two personal computers.

How to connect laptop to laptop via wifi?

The easiest way to create such a local network is to connect a laptop to a laptop via wifi. Because everything modern laptops already equipped with built-in wifi module, then you can only get by standard means operating system, and you won't need any additional software or equipment.

To connect 2 laptops wireless communication necessary:

• - on one of the computers (for example, from which data will be transferred), open “Network and Sharing Center” shared access" - "Change adapter settings";
• - on existing network call the menu and select “Properties” from the list presented;
• - then open the properties of “Internet Protocol 4 (TCP/IP)”: the parameters for obtaining the “ip address” should be set to “Automatic”;

Next, on both computers, open “Edit Extra options shared access" and in the drop-down list, make sure that the items indicated in the following figure are active; these parameters open general access to the network).

Additionally, you should disable password protection in the “All networks” section;

Now you need to create: open the “Command Prompt” (Win + P then cmd) and enter the command “ netsh wlan set hostednetwork mode=allow ssid=____ key=____", where "ssid=" is the name the network being created, “key=” is the security key for connecting to the network;

Now all that remains is to start the network: for this we use the same “ Command line"with the command "netsh wlan start hostednetwork";

The network is active, now from the second laptop search for available " wifi networks"and connect to the network created in the previous step by entering the security key;

To connect to the target device, enter address bar“Explorer” - double slash \\ + : it may look like this \\192.168.1.2, the address can be found in the “Network Status” - “Information” section.

How to connect laptop to laptop via network cable?

The second method involves insignificant costs for the purchase of a “LAN cable”, crimped in a crossover method (reverse), and the process of setting up a local network between laptops is much simpler than described above. But you will have to pay for the connection speed with local network mobility. And the settings will really take no more than a couple of minutes:

• - connect the laptops to each other with a “LAN cable”;
• - in the Network and Sharing Center, open Change adapter settings - Internet Protocol 4 (TCP/IP) properties. You can also access network connections using the “ncpa.cpl” command;

• - enter 192.168.0.1 in the “ip address” line, the subnet mask will be determined automatically, and the default gateway can be left blank;

• from the second computer, do the same steps, only in the “ip address” line indicate as for the first laptop, but one more - 192.168.0.2;

The local network between the two laptops is configured. You can connect to a computer using the same principle: \\ip_address or open “My Computer” - “Network” and find the laptop you need in the list.

If required device undecided, check all the checkboxes network discovery you set in the "Change advanced sharing settings" section.

In combination with this method, you can use third party programs for transferring files from laptop to laptop: perfect for this job free program"HFS" (HTTP File Server), which does not require installation.

How to connect laptop to laptop via USB?

If these options are not suitable for you, you can use the “Easy Transfer Cable” adapter to connect laptops to each other, using “ usb ports» laptops.

Price of this cable small: for a decent proven option you will have to pay about 500 rubles (for example, “ Windows Easy Transfer Cable" from "ST Lab").

So, to connect a laptop to a laptop via USB, connect the computers with an “Easy Transfer Cable” adapter and run the “Total Comander” program on both PCs. Next, on each computer, open the “Network” submenu and select “Establish a connection via LPT/USB port.”

Now you need to choose which laptop will act as a “Server” and which one will act as a “Client” (a kind of flash drive).

But this method not ideal, there are also some disadvantages:

• - the computer that will receive the file may be unavailable until the transfer is completed;
• - errors may occur when transferring between different-bit operating systems (between 64-bit and 32-bit or vice versa);
• - errors when transferring files between OSes with different languages.

Of all the above methods, the best option creating a local network laptop - laptop is a wireless connection option. It is more portable because it does not require any wires and does not have a significant impact on the performance of laptops. In addition, when connecting a laptop to a laptop via wifi, you can connect an unlimited number of devices with enough high speed data transmission.

In this article we will take a detailed look at the process of connecting a laptop or Windows 7 computer to the Internet via Wi-Fi. I think the article will be useful to many, since many questions always arise when connecting to Wi-Fi for the first time. As a rule, they are associated with installing the necessary drivers, enabling wireless adapter on a laptop, etc. More on this a little later.

The laptop is generally a great thing. I don’t really understand people who are buying desktop computers now. Only for serious games. Well, you must admit, it’s much more convenient with a laptop. If you want to big screen, then you can connect it to a monitor or TV. It makes no noise and you can take it with you if necessary. And also, all modern (and not so modern) laptops have a built-in Wi-Fi module. A receiver that allows you to connect your laptop to the Internet via wireless wifi networks. In the case of a desktop computer, you will need to buy .

All you need is to buy and install (if you don't have it yet), it will distribute Wi-Fi to which you connect your laptop. You can connect your computer to free Wi-Fi networks in cafes, shops, etc. Or, to unsecured network your neighbor :) This is much more convenient than laying a network cable. If for normal desktop computer This is still normal, but for a laptop this is no longer the case. And it’s not convenient to move around the house with this wire all the time.

Connecting a laptop to the Internet is not difficult, provided that the Wi-Fi driver is installed. Many people have a lot of problems because of the driver. If you simply haven't installed the driver on your Wi-Fi receiver, or you installed Windows yourself and did not install it, then you will not be able to connect to Wi-Fi. But perhaps you already have everything installed and configured, so let’s first look at the process normal connection To wireless network. If you don't learn from you, there won't be wireless connection etc., then read the article to the end, we will look at possible problems.

Connecting the laptop to Wi-Fi

Let's first look at the connection process without any settings or checks. Why complicate everything, perhaps you already have everything set up. If everything is fine, your laptop sees the wireless network and is ready to connect, then the Internet connection icon in the notification panel will look like this:

Connection status, which looks like network level with an asterisk (like the picture above) says that the laptop sees available networks and is ready to connect to them. Click on this icon, then select the Wi-Fi network to which we need to connect and click the button Connection. In Windows 10, the process of connecting to Wi-Fi is slightly different. If it is needed, detailed instructions.

If the network is password protected, a window will appear in which you need to enter a password and confirm the connection by pressing the button Ok.

That's all, your laptop should connect to Wi-Fi networks. The connection status will be like this:

You can use the Internet.

If you see the connection status, it looks like this:

This means that most likely everything is configured on your laptop, but the laptop simply does not see the networks available for connection. Perhaps there is simply no coverage in this place. If you are connecting to your network, check that the router is turned on. If enabled, then .

This is exactly how the connection will go when you have the driver installed on Wi-Fi adapter and the adapter itself is included. But very often the adapter on the laptop is turned off, or no one installed the driver for it at all. In such cases, many questions arise. Now we will examine in detail both cases, due to which you may have problems connecting your laptop to a wireless network.

Enable "Wireless network connection" on the laptop

If your wireless connection is disabled, or the Wi-Fi driver is not installed, the connection status will look like this:

This means that there is no way to connect to the Internet via Wi-Fi, and there is no connection via a network cable. As I wrote above, this happens due to the adapter being turned off, or due to the lack of a driver. Let's first check if you have "Wireless" turned off. network connection". This is of course unlikely, unless you turned it off yourself, but you need to check.

Click on the internet connection icon and select Network and Sharing Center.

Then select Change adapter settings.

Looking at the adapter "Wireless network connection", if it is disabled, then click on it right click mouse and select Turn on.

After this, the connection status should appear "Yes" available connections" (if there is a Wi-Fi network within the radius).

We enable wireless connections using the buttons on the laptop

It seems to me that now manufacturers no longer install individual buttons For turn on Wi-Fi adapter. But, if you are having problems connecting to Wi-Fi, then please check if there is special button to disable/enable wireless connections on your laptop. I know for sure that Toshiba loved making such switches.

Nowadays, on laptops, a keyboard shortcut is used to disable/enable the wireless network. As a rule, different manufacturers, the keys are different. But usually it's Fn+F2. So on Asus laptops. You can look at yourself, there should be a network icon on the key that is pressed in conjunction with Fn. Something like this:

True, for me the combination of these buttons is responsible for turning off Bluetooth. It doesn't seem to respond to Wi-Fi at all. But yours may be different. It's definitely worth checking out.

If in the adapter management window there is no “Wireless network connection” adapter at all, but there is definitely Wi-Fi on your computer/laptop, then this means that The driver for the Wi-Fi adapter is not installed.

Now we will check everything and try to solve this problem.

Check and install the driver for Wi-Fi

I have not yet seen a case where after Windows installations 7, the system itself installed the driver for the Wi-Fi adapter. This is much better in Windows 8. Windows 10 often installs itself necessary drivers. So, after installing Windows, in order to use Wi-Fi, you need to install a driver specifically for your laptop or adapter (very often, adapters from different manufacturers are installed in one laptop model. It is because of this that you can see several drivers for Wi-Fi on the manufacturer’s website).

We go to the device manager.

In Device Manager, open the tab Network adapters , and looking for a driver for Wi-Fi. I have it called Atheros AR9485WB-EG Wireless Network Adapter, it's installed. You should also have something like a Wireless Network Adapter.

If you don’t have a wireless connection, then most likely you won’t find an adapter either. You need to install the driver, then Wi-Fi will work. And yet, if the driver for the Wireless Network Adapter is not installed, then in the device manager there will be at least one unknown device with yellow exclamation point. It looks something like this:

This is most likely the same Wireless adapter that the laptop does not know how to work with.

Driver installation

All you need to do is download required driver and install it. It is best to download the driver from the official website of the manufacturer of your laptop/adapter, and for your laptop (or adapter) model. It’s best to find the official website of your laptop, for example Asus, through Google, then use the site search on the site, indicating the model of your laptop. Most likely your computer's page will be found, open it and look for downloads of utilities and drivers there. Find the Wireless driver and download it for the operating system you need.

Most likely, the driver will be in the archive. To install, run the .exe file from the archive. For example, an archive with a driver for my laptop:

After installing the driver, restart the laptop and try to connect to the wireless network, according to the instructions. I wrote in more detail about installing the driver in the article about .

If some points from the article remain unclear to you, or you were unable to connect your computer to Wi-Fi, then write about it in the comments, we will try to solve your problem.

In this article we will look in detail at how to connect the Internet to a laptop via a wireless network or using a twisted pair, consider the features of each type of connection, settings different versions OS and installed components.

Cable Internet technology options

Conventionally, all options for connecting to the Internet via cable can be divided into several main types.

• Dial-up connection. This is an Internet connection via cable, analog modem or the same telephone line. Used given access and in digital connection using ISDN technology, when installing the appropriate adapter.
• Dedicated communication channel. It involves the use of a separate line laid from a PC/laptop to equipment owned and maintained by the provider. There are two types of connection: with speeds up to 1.5 Mbit/s and up to 45 Mbit/s. It is considered most effective for large enterprises.
• DSL (Digital Subscriber Line) is one of the broadband access options with which you can connect wired Internet to a laptop. Provides data transfer speeds up to 50 Mbit/s. This is a digital connection using analog telephone lines.

How to connect the cable to a laptop

Connecting a laptop to wired internet In any case, it happens in this order:

• Dial-Up, connection is being configured telephone line to the modem, after that there is a cable connection from the modem to the laptop,
• a dedicated communication channel comes to your apartment via a twisted-pair connection, it can be connected either immediately after entering the apartment or after the router, this does not matter,
• DSL Internet also comes to the apartment via telephone cable, so it turns on only after connecting the modem.

Settings in the operating system (we will consider for different OS versions - XP-10)

In almost all operating systems Microsoft menu are almost the same, so the menu transitions are identical for all versions of Windows.

1. Go to the “Start” menu> “Control Panel”.

1. Find “Internet Connection”.

1. Paragraph " Network connection”, create a new connection.
2. Following the instructions of the New Connection Wizard, enter the login and password provided by your Internet provider.
3. We find the properties of the TCP/IP protocol in the network tab and check that obtaining an IP address and DNS server is turned on in automatic mode.

PPPoE

One of the DSL connection options (Point-to-point protocol over Ethernet) stands out from others due to its frequency of use (the majority of connected, modern access points occur via the PPPoE protocol). The connection takes place using an individual login and password.

Static or dynamic ip

A dynamic IP address is given free of charge by your ISP to connect to the Internet and can be assigned to another computer when you re-enter the network. The static version of IP (Internet Protocol) is purchased for additional money and provides more options, and is entered manually when connecting to the Internet.

VPN over L2TP/PPTP

VPN ( Virtual Private Network) – the ability to create virtual network on top of the physical.

• PPTP. Connection protocol supported any VPN network initially (the first protocol introduced by Microsoft). Is the fastest on this moment connection protocol.
• L2TP. Tunneled layer 2 protocol, almost all devices currently support it. Simple setup, but lack of encryption and data protection makes it dependent on the additional IPSec protocol.

Wireless connection via Wi-Fi (from router)

Turning on the Internet on a laptop provided that the Wi-Fi network from the router is configured is very simple task. There are several conditions necessary for this.

• Availability of the network name and password for it.
• A laptop with a working Wi-Fi module.

The connection occurs according to the following scenario.

1. We turn on the router to the network and wait wifi downloads protocol.
2. We turn on wireless networks on the laptop.
3. We open the overview of wireless networks and find the one we need.

1. In the menu that opens, enter the password and click the connect button.

Checking for an adapter

The presence of a wireless adapter can be verified by the presence of a picture on the laptop box. If you bought a laptop second-hand without a box, then there will definitely be a duplicate mark on the case about the wireless adapter.

Driver installation

Installing network card drivers on your computer is an important part of connecting to the Internet. Without network driver the laptop won't detect it WiFi adapter. The drivers are installed from the disk that comes with the laptop; insert it into the CD drive and follow the instructions of the installation assistant.

Necessary system settings for connection

To set up the Internet, you need to check automatic receipt IP addresses and DNS servers. These settings are located along the path Start>Control Panel>Network and Sharing Management>Connection Properties>Internet Protocol Version 4 Properties.

Connection via mobile internet

It is also possible to connect a laptop to the Internet via a mobile phone.

1. We set up an Internet access point on the smartphone.
2. We connect the phone to the laptop via USB or Wi-Fi.
3. Install drivers (depending on the phone brand) and connect to the Internet.

3G and 4G modems and routers

Connecting to the Internet is very easy using 3 and 4G modems, just install the drivers and connect to the Internet.

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 connect a computer (or laptop) to a router using a LAN cable.

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, maybe it will 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 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 connection 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 through which Internet is coming connect 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 is possible that the network card is simply 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.
