The Internet does not connect to the laptop via cable. Connecting a laptop to the Internet via cable. No connections available

Often, many problems arise when you need to connect your computer via wireless network to the router or router. And if a network cable is used for this process, then there are usually no obstacles. Please note that this connection requires an active Internet connection.

At the same time, it should be understood that even in such simple manipulations, some difficulties and errors may arise, which will result in the fact that even when connecting cable Internet via a LAN cable, the device will not gain access to the World Wide Web.

In this article we will look at how you can connect the Internet via cable to your computer or laptop. All manipulations are discussed using an example operating system Windows 7, but they will also be valid for later versions.

How to connect cable internet to a computer

In order to do this, we will need:

A Wi-Fi router that has at least one unoccupied LAN cable connector (its color is yellow).
Network cable. This cable, which has a minimum length, is included with the router you purchased. But if you need a longer cable, you can purchase it at one of the computer stores.
PC with network card or connector.

Next, we need to take a network cable, and then connect one end of it to the LAN connector yellow color, located on the back of the router. It does not matter which of the several connectors the cable will be connected to. The other end must be connected to the corresponding connector on the device.

Now check if the indicator lights up indicating that a computer has been connected to the LAN connector. If yes, then next you need to look at the computer display. In the notification panel, in the lower right corner, the connection status should be displayed without error marks. If so, then the device is connected to the Internet.

Connecting the Internet without a router

To ensure a direct connection from the ISP to your PC's network card, you need to connect the cable directly to a port called Ethernet. It is located on the back of the computer.

After this, you should set up a new connection.

Step-by-step setup networks in Windows 7:

Using the Start menu:
Go to "Control Panel".
When the window with the panel opens, you need to go to the “Network Center”.
In the left column, click on “Change adapter settings.”
Then, in the folder where all existing connections are located, you should right-click on the Ethernet connection, and then in context menu to the “Properties” inscription.
After this, you will need to select the TCP/IPv4 protocol and go to its “Properties” again.
That's almost all. If you need the connection to be provided via a static IP, you should check with your provider about the field settings in the window that opens.
If you require a dynamic IP, then you do not need to change anything in the protocol properties window. Any settings and field values will be "dictated" by your system in automatic mode. Just press the “Ok” button, and the Internet is connected to your device via a cable.

We connect the Internet via cable to a new PC

In a situation where you need to connect the network to a new device, the algorithm will be slightly different. In such a situation, you will need to create and configure a connection from scratch. Initially, you will need to insert the cable directly into the computer's network card.

Now we do the following:

Go back to the Control Panel.
And we go to the network control center.
Here we will need to select setting up a new connection (it can be different types– via modem, VPN or wireless).
In the window that appears, select the option called “Connect to the Internet.” Click the “Next” button.
Here you need to select the “High Speed” option.
In the next window you need to fill in the fields. The provider has given you a login and password to connect to the network; they must be entered in the appropriate windows. Check the boxes next to displaying the entered characters and remembering the entered password.

If the manipulations are performed correctly, then in the lower right part of your computer or laptop you will see a symbol indicating the newly created connection.

Why doesn't the Internet work? Problem solving

The reasons can be varied, and to eliminate each of them you will need to perform certain actions.

Checking whether the internet cable is connected. You should make sure that the cable is actually connected and that it is connected to the correct connector.
The cable or network card is faulty, or the LAN port on the computer does not work. If there are no problems connecting the cable, then you should make sure that the computer really connects to the network. Pay attention to the indicator on the router or near the connector in the PC. Also, at the bottom of the taskbar, the connection icon will be covered with a red cross. In this situation, it is necessary to repair the network card or troubleshoot the cable.
The network is not working although the indicator is blinking. In such a situation, you must first install/reinstall the network driver.
Driver installation is complete, but there is no connection? Go to the control panel, and then to the network and control center. If the word “Disabled” is greyed out next to your Ethernet connection, right-click on the connection and then click on “Enable”.
The connection must be configured. You can find how to do this above in the article.
The router is faulty. If the cable is not connected to the computer directly, but through a router, then the malfunction may be caused by incorrect router settings. Check this by connecting the network cable directly to the device.
The period paid to the provider has ended. Contact your provider's technical support and check your balance status.
The connection was blocked by viruses. It is necessary to check the entire system using an antivirus.

The reasons for the lack of connection to the network can be both software and physical. First, you should carry out diagnostics, which consists of three main stages: checking the integrity of the wires, setting up the router and computer.

Problems on the provider side

It may not be your fault that you are not connected to the Internet. If the system worked properly, additional software was not installed, the settings were not changed, then the provider is probably to blame. Call the customer service center and find out if they have problems with the network. Additionally, you can recruit friends who use the services of a similar company.

If you have mobile Internet, go to the provider’s official group or website. Users react quickly to outages, so they often write their complaints in the group or on the provider’s page. They will be an indicator to you that shutdown is widespread. There is only one solution - wait for corrections.

Checking the physical connection

As a rule, if there is no Internet connection, you will see a red circle with a cross on the tray icon (on the right). This is a clear sign that there is a break somewhere. A rare situation is damage to the network cable or connector. Carefully inspect the entire length of the wire throughout the apartment, looking for cracks or other defects. Check the connection to the site where the hub is being installed for several apartments. It is impossible to determine any further breaks (the cable is underground). This is the job of the provider's specialists. If the plug is damaged, you will have to change it, and this is difficult to do without special tools and skill.

Problems with the router and their solutions

Up to 80% of all problems are related to incorrect work router. If the Internet does not connect when connected directly, skip this section.

Troubleshooting is possible through a simple reboot. If you have to do this regularly to restore operation, take the device to a service center to diagnose and identify the cause. Restarting the router is done in the following ways:

Turn off the power supply. Wait 10 seconds and then turn it back on;
press the Power/On/Off button (if equipped) to turn off. Then activate the device.

At the same time, restart your PC. Do not press the Reset button on the modem (this is full reset to factory settings as a last resort).

Settings in the router web interface

All changes to router parameters are made in the system menu - web interface. We will tell you how to get into it and what changes should be made.

Login to the web interface

To enter you need:

IP address for accessing the modem;
login and password for the device.

The information is located on a label attached to the case. Look for the Default Settings or “Username/Password” block. Write these values down on a piece of paper or remember them.

Open a browser on the computer/laptop that is physically connected to the modem. Enter the factory IP, which is copied from the label.
In the window, enter Login and password. Typically this is English word admin.

The main menu of the router will open.

Setting up an internal network

The LAN item is responsible for setting the local network parameters (“ The local network"). At the user's discretion, the range of working IP addresses is set here. It must correspond to one of three ranges allocated for private networks:

Check the device's default gateway. Through it, exchanges occur with other devices. Typically the default is 192.168.0.1 or 192.168.1.1 (if you are using that range).

Setting up an Internet connection

The second important step is to correctly configure the connection type. Providers can use:

If there is no internet connection, make sure you set the correct type. Call the supplier and find out necessary information. Some modems have a “detect” button in the interface. With its help, the connection type is set correctly automatically.

Changing the router's IP address

For the network to work, it is often necessary to set the correct router address. This is done as follows:

go to the menu and select the LAN section;
enter the required parameters in the IP-address field;
Click the “Save” button.

The address must be within the local network range.

MAC address cloning

Some providers provide Internet access to a specific Mac address, for example, a computer. There is a need to change this parameter for the router. Most manufacturers include a Mac address cloning feature. It is activated as follows:

If you can't find the function, read the technical manual.

MTU setting

MTU determines the maximum level of information transfer. This parameter controls the number of bits with useful information, placed in the package. Everything is forwarded without fragmentation, so you can increase the transfer speed. As a rule, the MTU is set automatically by the device, but not always correctly. A correctly adjusted level will allow you to:

expand the channel;
minimize unnecessary load on the channel, which will increase speed;
remove or minimize packet transmission errors.

Use the command Ping www.google.com –f –l 1500. Start with exactly 1500. Next, decrease the parameter by 5 units, and then check how many packets are lost. If 100% of the data is successfully transferred, change this parameter in the router settings (in the connection type selection menu). Please note that the limit values depend directly on the protocol.

Problems with your PC or laptop

If all else fails and the “no Internet connection” error remains, check your PC.

Reinstalling the network card driver

There is special software for each PC/laptop component. Windows usually installs drivers on its own from its database, but this procedure does not always help. It is recommended to install everything yourself.

The best method is to download the required software from the official website of the network card manufacturer. Find the “Drivers” or “Support” item in the menu, indicate the model and version of the OS you are using. Download the installer and then run the installation.

The second option is Windows tools:

right-click on the “My Computer” icon and select the “Properties” line;
select "Device Manager";
click on network card RMB, and then on the line “Update drivers”.

The driver may be missing for some reason. Then specialized utilities, for example, Driver Genius, will come in handy. Download it from the developers site and then update everything outdated drivers. The utility database is regularly updated, so it is always up to date.

Replacing the MAC address of a network card

Users can change the MAC of the network card itself in two ways. The first includes the following steps:

Remember the MAC address includes exactly 12 digits in hexadecimal s/s only. After making changes, be sure to check the success of the operation via console command ipconfig /all.

The second method involves entering the address through the registry. Go to the path shown in the image and in the DriverDesc parameter change the NetworkAdress line.

Enabling the network card in BIOS

In some situations, it is necessary to enable “networking” in the BIOS. We will look at the procedure using the example of a classic BIOS (not UEFI). To do this, enter the BIOS and follow these steps:

Now let's look at how to perform a similar process on UEFI BIOS versions (example for Asus motherboards):

open the “Advanced” tab;
select OnBoard Devices Configuration;
set LanController to Enabled state.

Diagnosing Internet connection problems

We recommend using standard means Windows OS to troubleshoot Internet problems. Often this procedure saves you from connection errors, which eliminates the need to study the system menu and BIOS. To start you need:

Additionally activate checks for network adapter And home group. Download and run the FixWin utility on the flash drive. FixWin is a powerful tool for troubleshooting operating systems from Microsoft.

IP Receiving Settings

Using a direct connection without a modem, set automatic receipt of addresses. These are necessary settings for the OS. They are installed quickly and easily:

After this, restart your computer and check the network is working.

Firewall check

The Windows system has its own protection against viruses and potentially dangerous resources. A “firewall” (or “fire wall”) can block access to specific or all sites. Luckily, it's easy enough to turn it off:

Remember that without installed antivirus your computer will be absolutely defenseless against malware from the global web.

Clearing the DNS cache and resetting TCP/IP protocol settings

Crashes in TCP protocol or DNS cache may cause connection loss. Users can reset the cache on their own:

These steps won't hurt system files, so perform them without fear for the safety of the operating system.

Enabling FIPS Compliance Mode

Try turning on federal compatibility mode. This current solution for residents of Russia. Its activation is carried out as follows:

The proxy server is not configured correctly

Often it is impossible to connect to sites due to incorrect proxy server settings. There is an option to change the proxy in the OS interface. Go to Internet Properties and then open the Connections tab. Click on the “Network Settings” button. Next, check the box to use a proxy. Enter the correct IP and port. You can obtain this information from your network administrator (service provider).

Internet does not work on your phone or tablet

If you can’t log into the network through mobile gadgets, for example, the Internet does not work on your tablet, then the most common reasons are:

compatibility frequency ranges router and smartphone;
activation of a wireless access point;
hidden network or not;
whether the DHCP server is activated on the modem;
Wi-Fi module damage;
Airplane mode is activated on the phone;
The smartphone does not support the WPA2-PSK encryption standard

If another device connects without problems, then the problem is in a specific device.

Diagnostics of Internet connection in Windows 10

If the Internet is connected to your computer or laptop but does not work and you are sure that the reason lies in incorrect settings, then you should perform a few simple operations. Let's start by pinging some popular site. To do this, press the Win+R key combination to display the “Run” window:

In the “Open” line we type the command cmd. Click on the “OK” button to open the window command line. We type the command:

ping yandex.ru

If you don’t like Yandex, you can use Google instead. Press the “Enter” key and look at the result. If everything is in order, then you will receive something like this response from the server:

If you receive a response like this:

Then we type another command:

Ping 77.88.8.8

This is the IP address of the public DNS server from Yandex, which is always available. Alternatively, you can ping the server from Google - 8.8.8.8. If the PC has access to an external network, then the response should be like this:

If a node pings via IP, but the sites do not open, then this usually means that the Internet is connected but does not work due to the fact that the DNS server address is not specified (or incorrectly specified) in the network card settings. I will tell you how to do this below.

If you see this answer:

Then it’s worth checking whether the router is accessible. To do this, it also needs to be pinged. You can see what IP address is used on it on a sticker, usually located at the bottom of the case. It's usually either or. I have a D-Link router and it uses the second option:

If the router pings, but the node is not on the Internet, then the reason is most likely again in the router or in its settings.
But if the router is unavailable, this is a reason to delve into the settings of the network adapter on the computer. But before that, try disabling your antivirus and firewall, since very often they are the cause of most network problems.

It didn’t help and the Internet is still connected but not working?! Well, then press the Win+R key combination again so that the “Run” window appears and enter the command ncpa.cpl.
If everything was done correctly, a network window should appear. Windows connections 10:

Right-click on the connection icon and select “Properties” from the menu. In the window that appears, double-click on the line “IP version 4 (TCP/IPv4)” to get to the protocol parameters:

Here we try to set automatic receipt of addresses and again check the access to the global web.
Still not working? Then check the box “Use the following addresses”:

You need to register an IP address from the subnet of your router. If its IP is 192.168.0.1, then set the computer to 192.168.0.2. If the router uses 192.168.1.1, then the PC will have 192.168.1.2. Mask 255.255.255.0. You must specify the router address as the gateway. Register it as your preferred DNS server. Alternative DNS can be specified as a server from Yandex 77.88.8.8 or from Google - 8.8.8.8.

As a rule, after this Internet access appears. If none of the tips helped you, then I’m afraid that you need to call a professional specialist who can determine the cause of the problem and can eliminate it. Good luck to all!

Often the user encounters yellow triangle on the "network" icon. It means that Internet does not connect, or there is no connection at all. An unexpected “surprise” occurs when a user surfs the Internet.

No internet, yellow signal

Why can't I connect to the Internet via cable?? Let's figure out what to do in this situation:

Now the Internet should work.

But there are providers that use static network settings and dedicated IP addresses. In this situation, the World Wide Web Setup Wizard notifies the user about this.

If this is your case, and The Internet does not connect to the computer via cable, go to the Internet IPv4 protocol, and manually write the required IP addresses. You should find out the gateway and mask from your provider by calling.

Well, the most common problem: The problem may be with the network provider itself. Call the technical support operator and ask whether the equipment works in your home and whether there is access to the global web.

There is a cable, no internet, red cross

And if Does your computer not connect to the Internet via cable? Let's look at the case when the network icon with a red cross through it is visible on the screen, and a message pops up stating that the network cable is not connected, which means Internet does not connect via cable.

Other actions

What else needs to be done:

Resetting the router

Rebooting the router does not always help. If you are sure that this is the problem, reset the settings. Manipulation is performed in two ways:

Conclusion

Using these tips, you can easily diagnose your PC yourself when internet doesn't connect, and identify network problems.

Correct them in time and continue using the Internet. Many users immediately call a technician, spending a lot of money to fix a simple problem. But you just need to experiment with the cable and settings for half an hour, and only if the problem persists, trust a professional.

If you do not want to pay for the services of the provider’s specialists, you can configure the Internet yourself. All you need to do is connect the cables correctly and install software settings. We will tell you how to connect a computer or laptop to the Internet, and look at setting up several types of connections in your router.

Types of wired Internet connection

Active development of technology has led to the emergence of several types of cable connection of local or global network. Each provider can offer clients one or more types wired connection. You may find:

To connect yourself wired Internet, you need to make settings in the OS and the router itself (if used).

Connecting the cable to the computer

Once the provider's specialists have laid the cable, the question arises where and how to insert its end. There are two options for connecting cable Internet, each of which will be discussed separately.

Directly

You can connect your computer directly to the Internet only through an Ethernet connection. ADSL requires a special modem, and if using fiber only, you will need a media converter, SFP module or optical terminal. Take the end of the LAN cable from your ISP and then plug it into the port on your network (motherboard) card. The port should light up orange. After this, software configuration is carried out.

Via router

Users are often interested in how to connect to the Internet via a modem. The procedure is not difficult and consists of several simple steps:

Connect the Internet cable to the WAN port. As a rule, a router has one, but it differs in color from all the others.
Connect one of the LAN outputs to the input on the network card of your PC or laptop.
Don't forget to plug your router into a power outlet.

Thanks to the router, you can connect several devices to home network, limited only by the number of LAN ports.

Setting up different types of network connections

The user must perform all other manipulations to connect to the Internet in the operating system settings and the router web interface. We will tell you how to configure static and dynamic IP, L2TP and PPPoE connections.

Dynamic IP

According to the technology, dynamic distribution involves issuing different IPs for each connection, while the address remains unchanged during the session. To configure, follow the steps below:

The data will be received from the provider automatically. Now you know how easy it is to set up a dynamic IP.

Static IP

Your address always remains the same, even when you restart network equipment and PC. In this case, the user needs to request the following data from the provider: IP address, network mask, default gateway and DNS server. Then, in the Network section, select Static IP and fill out the fields. Don’t forget to save your changes after entering so that everything is connected correctly.

PPPoE connection

Connecting to the Internet via PPPoE can be done via Windows interface. Please ask your provider in advance or look in the documentation for login information (login and password). Setup on Windows 7 OS contains the following steps:

You can also create a connection in the router by selecting the appropriate type in the “Network” tab.

L2TP setup

This is a relatively new type of Internet connection that is actively offered mobile operators and other providers. As in the previous case, you can create a connection using the operating system.
