The Internet does not work via the network cable from the router. Update or reinstall drivers. If all user attempts are unsuccessful

This problem exists, and many users have suffered from it. Its essence is as follows: a Wi-Fi router is purchased, it is connected and configured, but the Internet is still missing and the Internet is not distributed to remote devices. A network without Internet access is a situation that has various causes:

• The router may be faulty, which is quite rare, but it does happen.
• The router may not be configured correctly.
• WAN use may be limited by your provider. For example, if you are late in paying for services.
• The problem may be with your computer or laptop.

And some others. A network without Internet access can be tested on different devices. If the Internet is not available when different subscribers are connected to the router, this means that the problem should be looked for in the router or find out whether the network is limited by the provider.

The latter is especially easy to do - you just need to call the operator. But most often, a network without Internet access is caused by incorrect router settings. Next we will consider just such a situation.

What does the picture look like in practice?

Below is a picture that shows a typical grid without Internet access:

All this is completely independent of the router model, but is only a consequence of incorrect settings. To begin with, such settings need to be “reset” - that is, the router must be transferred to the state in which it was immediately after leaving the assembly line. Each such device has a button marked “Reset”. It can be located either on the side of the device body or on its back wall.

As a rule, the button is small in size. This is done to prevent it from being pressed accidentally. Other protective measure– the need to hold the button pressed for some time (usually about 10 seconds). This is the only way to make it work. So, take an object with a sharp tip and press it on the button, holding it for a while. A signal that the settings have been reset will be multiple blinking of the front panel lights.

Beginners may find the following figure helpful:

It shows the correct connection of the ISP cables, interconnect cable and power supply cord. Check if your router connection matches what is shown in this picture.

Is the connection type specified correctly?

Among the router's software settings, there is one parameter that is critical for the normal functioning of Wi-Fi. This is a type of Internet connection. If you specify the connection type incorrectly, access to the Internet becomes impossible. If, when physically correctly connecting the router to the computer, when setting up the router, Windows writes “without access to the Internet,” first check the connection type. this parameter can take the following values:

• PPPoE.
• L2TP.
• PPTP.
• Static IP.
• Dynamic IP.

Each connection type requires its own settings. You should ask your provider what type of connection it uses to connect subscribers. The most basic way to connect to a network is to use a dynamically assigned address.

In this case, you will not need to specify any additional parameters, such as IP address, gateway addresses, etc. PPTP, PPPoE and L2TP usually require you to specify a login and password assigned to you by your provider. This data is usually specified in the connection agreement. Static IP will require you to specify the IP address, gateway address and DNS addresses in the router settings. They must match those of the computer connected to the device. It’s easy to find out all these parameters by typing the command in the Windows console: ipconfig /all.

Binding by MAC address

This is a common technology for identifying users by the provider. Each network device is assigned a unique identifier - the so-called MAC address. When connecting, the provider can control this parameter and, if it does not comply with what is stated in the contract and the provider’s internal database, reset the connection. Many people have encountered this situation when reconnecting the provider cable to another computer or laptop. In this situation, you have to manually enter the MAC address in the Internet connection settings.

About the same thing has to be done when connecting to a router network. To do this, there is a special interface in its settings, usually equipped with a button with an inscription like “Clone MAC Address” or something like that. If you have correctly specified the type and parameters of your network connection, but you still cannot connect to the Internet, try cloning the MAC address. Or call your provider asking for advice on this matter. Detailed information may also be available on your Internet service provider's website.

How to find out the MAC address of your computer? Using the above command: ipconfig /all. Its output list also contains such information.

Other possible causes of the problem

Be sure to check the network on a computer with a directly connected provider cable (that is, without using a router). You may have configured the network settings on the computer itself incorrectly.

If the network is lost or there is no access to the Internet, this may be the result of a broken cable from the service provider or a malfunction of the home equipment responsible for distributing the network to apartments. In both cases, the router has nothing to do with it, but you need to check all the options.

If you are using a configuration of an ADSL modem and router, then in the settings of the latter, enter a dynamic IP address, regardless of the provider’s technology. All necessary parameters must be specified in the ADSL modem settings.

Check that the Internet settings on the devices connected to the router are correct. Incorrect settings may also cause the “connected but not able to access the Internet” message.

The network signal may disappear for other reasons. For example, you may find that wireless connection missing, and when connecting devices via cable, the problem disappears. This can also be caused by various reasons. The simplest of them is that the signal does not reach the subscriber due to the presence of obstacles in its path. Another option is that the signal can be suppressed by external devices operating at the same frequency as the router.

A loose connection between the provider cable and the router connector can also cause devices to operate without access to the Internet. On the body of any good router there is a special light that indicates that the contact is not strong enough.

Another one possible reason network failures – problems with Windows or another operating system installed on the subscriber device. This should also be kept in mind when the error we are considering appears. To detect such failures and fix them, you can try using the built-in Windows tool: “Diagnostic Center”:

Remember, you need to configure everything carefully and, if possible, with knowledge of the matter. If our information about what to do when working without access to the Internet was useful to you and the Internet is available, then we can consider our task completed. But it may turn out differently: I connect, but it says that the network works without the Internet - try writing to us about this, providing detailed information- we will tell you how to fix it.

This instruction contains step-by-step information on what to do if the Internet does not work on a computer with Windows 10, 8 and Windows 7 in various scenarios: the Internet disappeared and stopped connecting for no reason via the provider’s cable or via a router, the Internet only stopped working in the browser or certain programs, works on the old one, but does not work on the new computer and in other situations.

Note: In my experience, about 5 percent of the time (and that's not a small number) the reason the Internet suddenly stops working is with the message "Not connected. There are no connections available" in the notification area and "Network cable is not connected" in the list of connections indicates that the LAN cable is really not connected: check and reconnect (even if visually it seems that there are no problems) the cable both on the side of the computer's network card connector, and from the LAN connector on the router, if the connection is made through it.

The Internet is not only in the browser

I'll start with one of the most common cases: the Internet does not work in the browser, but Skype and other instant messengers, a torrent client continue to connect to the Internet, Windows can check for updates.

Usually in such a situation, the connection icon in the notification area indicates that there is Internet access, although in fact this is not the case.

The reasons in this case may be unwanted programs on the computer, changed network connection settings, problems with DNS servers, sometimes an incorrectly removed antivirus or a Windows update (“major update” in Windows 10 terminology) with an antivirus installed.

I discussed this situation in detail in a separate guide: it describes in detail how to fix the problem.

Checking the network connection via local network (Ethernet)

If the first option does not suit your situation, then I recommend following these steps to check your Internet connection:

Let's stop at point 6 - connection via local network shows that everything is fine (on, there is a network name), but there is no Internet (this may be accompanied by the message “No Internet access” and yellow Exclamation point next to the connection icon in the notification area).

LAN connection is active, but there is no Internet (no Internet access)

In a situation where the cable connection works, but there is no Internet, there are several common causes of the problem:

1. If the connection is made through a router: there is something wrong with the cable in the WAN (Internet) port on the router. Check all cable connections.
2. Also, for the situation with the router: the Internet connection settings on the router have gone wrong, check (see). Even if the settings are correct, check the connection status in the router’s web interface (if it’s not active, then for some reason the connection cannot be established, perhaps the 3rd point is to blame).
3. Temporary lack of Internet access on the part of the provider - this does not happen often, but it does happen. In this case, the Internet will not be available on other devices via the same network (check if possible), the problem is usually fixed within a day.
4. Problems with parameters network connection(DNS access, proxy server parameters, TCP/IP parameters). Solutions for this case are described in the article mentioned above and in a separate material.

For the 4th point of those actions that you can try first:

If these two methods do not help, try more sophisticated methods of solving the problem from the separate instructions given above in paragraph 4.

Note: if you have just installed a router, connected it to your computer with a cable, and there is no Internet on the computer, then most likely you simply have not configured your router correctly yet. Once this is done, the Internet should appear.

Computer network card drivers and disabling LAN in BIOS

If the problem with the Internet appeared after reinstalling Windows 10, 8 or Windows 7, or in cases where the local network connection is not listed in the list of network connections, the problem is most likely caused by the fact that the necessary network card drivers are not installed. Less often - because the Ethernet adapter is disabled in the BIOS (UEFI) of the computer.

In this case, you should follow these steps:

Perhaps in this context it will be useful: (if there are unknown devices in the list in the task manager).

Network card parameters in BIOS (UEFI)

Sometimes it may turn out that the network adapter is disabled in the BIOS. In this case, you definitely won’t see network cards in the device manager, and local network connections in the list of connections.

The parameters of the computer's built-in network card can be located in different sections of the BIOS; the task is to find and enable it (set to Enabled). This might help: (also relevant for other systems).

Typical BIOS sections where the required item may be located:

• Advanced - Hardware
• Integrated Peripherals
• On-board device configuration

If the adapter is disabled in one of these or similar sections of the LAN (may be called Ethernet, NIC), try turning it on, saving the settings and restarting the computer.

Additional Information

If by now you have been able to figure out why the Internet is not working, as well as making it work, the following information may be useful:

• In Windows, Control Panel - Troubleshooting has a tool to automatically fix Internet connection problems. If it does not fix the situation, but provides a description of the problem, try searching the Internet for the text of the problem. One of the common cases: .
• If you have Windows 10, look at the following two materials, they may work: , .
• If you have a new computer or motherboard, and your ISP restricts Internet access by MAC address, you should tell them the new MAC address.

I hope that one of the options for solving the problem with the Internet on a computer via cable was suitable for your case. If not, describe the situation in the comments, I will try to help.

Today for many it is already an urgent need. Modern hardware and operating systems are becoming more and more intelligent, and the user is less and less likely to need to do anything to configure. However, occasionally such a need arises. Today we will tell you how to solve the problem if your computer reports that you are connected to a network without access to the Internet, and next to the connections icon you see a yellow triangle with an exclamation mark.

Microsoft operating systems, starting with Windows 7, constantly monitor network connections, and since global network is unavailable, they report it immediately. There are many reasons why your computer may not have an Internet connection. These could be problems with the provider, incorrect equipment configuration on the part of the user, or failures in the operation of network protocols. Today it is becoming more widespread new protocol IPv6, but its percentage is still very small, especially in home networks, so the main attention will be paid old version- IPv4.

Connecting via a router via a network cable without access to the Internet

Problems with the provider

Yesterday everything worked, but today this warning appeared. If this happened to you without visible reasons, then in most cases the problem is with the provider. Therefore, before doing anything yourself, call technical support. Most often, data transmission lines are damaged, some engineering works or you simply forgot to top up your account on time.

You may hear in response that everything is working well with the provider, then you need to check your network and, if necessary, configure it. The support service will probably offer the services of its technician, but, firstly, his services are not free, and secondly, by the time the technician gets to you, you may have time to solve the problem yourself.

Physical connection problem

It is not so rare that the culprit is a partially broken network cable or a loose connection in the connector. And if you have pets or children, then the likelihood of such a development of events increases. Even Wi-Fi users should not forget that there will also be a cable running to the wireless router. Check the integrity of all wiring - are there any strong kinks anywhere, are all plugs firmly inserted into the sockets and are they inserted where they really need to be. Provided that no problem is found here, we move on to the next step.

Connecting via local network Windows 7 without access to the Internet

It happens that the installed router simply freezes. In this case it helps. To do this, just turn off its power and connect it again after a few seconds. It won't hurt to restart your computer at the same time. If your router freezes like this with annoying regularity, consider buying a new device. You should also try connecting the Internet cable directly to your PC or laptop. If there is no result, let’s first deal with the computer.

Checking your computer settings

It is possible that the problem arose “out of the blue”, then problems with the settings on the computer should not arise; much more often the problem arises during the initial configuration or making any changes to an already working network. First of all, you need to check that the IP address of your computer is correct by pressing Win+R on your keyboard at the same time. The Run window will open. In its line, enter ncpa.cpl and click OK. The network connections window will appear. It may happen that there are several of them, but the required one will not be crossed out with a red cross and its name is similar to “Local Area Connection” or “Wireless Connection” (in the case of using Wi-Fi). Right-click on the desired connection and go to properties, where the list will contain lines with IPv4 and IPv6 entries. Check the box next to IPv6, and double-click on IPv4. Check the boxes to automatically receive settings and save the changes. If access to the Internet does not appear, move on.

Setting up a local network connection in Windows 7

Finding out the router address

Perhaps you didn’t have to do anything in the previous window, the settings for obtaining IPv4 and IPv6 protocol addresses are automatic and everything was initially as it should be. Then you just need to configure the router, for which you need to know its address. Right-click on the connection again and select “Status” and then click “Details”. There will be several lines in the window that appears; we are interested in “IPv4 Address”. If you see an entry like 192.168.x.x, remember or write down what is indicated opposite “IPv4 DHCP server” - this will be its address. It may be that the computer is not able to receive the settings automatically, then the entry will look like 169.254.x.x. You can find out the router’s IP from its documentation, or it is indicated on the device’s case, and most often it is 192.168.0.1 or 192.168.1.1. Open your browser and enter the established IP in the address bar, and if it is correct, you will be prompted to enter your login and password.

Internet Protocol Version 4 (TCP/IPv4) Properties

Setting up an internal network on the router

After correctly entering your credentials, you will be taken to the router control panel, and further actions depend on the device model and its firmware. You need to find a DHCP server control, which is responsible for automatically obtaining IP addresses and other parameters necessary for the network to function properly. Look for blocks whose names include DHCP settings, DHCP server, or similar. The block will contain a switch with the values ​​Enable or Disable. Most often, these settings are located in the LAN section. Enable the DHCP server, save the changes and reboot the router. Once this is done, an Internet connection will appear on your computer.

Check your connection settings to your provider

You should not jump to hasty conclusions if the previous steps did not help set up the connection. Since the network is still not working normally, we check the connection with the provider, for which in the router control panel, go to the appropriate section. Almost all manufacturers call these options WAN or Internet. There are quite a lot of settings options in this section. Which ones are intended for you, you can find out from the contract or from the technical support of your service provider.

Reinstalling network card drivers and checking the firewall

It makes sense to do this when you are sure that all previous settings are correct, the connection with the provider is established, but the network cannot be configured normally. The best option would be to download the most recent version of the driver from the manufacturer's website, which, it seems, will require going to a friend or neighbor. If this is not possible, the driver included with the installation disk. After reinstalling, be sure to restart your computer. Here it is also necessary to note driver failures that occur due to the installed software, which makes changes to the operation of network protocols on the computer. The most common representatives are antiviruses and firewalls. Make sure that such programs are not installed, and if they are, disable or remove them during the test, as they may block the connection.

Replacing the MAC address of a network card

Problems with MAC addresses sometimes arise in cases where the network is very large, but it is still worth eliminating it. On your computer, go to the device manager, press the Win+R keys, enter devmgmt.msc and click OK. The device manager will launch, where you need to find the “Network adapters” section, expand it and select the network card with which the PC is connected. After double-clicking on it, in a new window, on the “Advanced” tab, select the Network address option and enter any twelve digits in the empty field on the right. After that, reboot and look at the result.

Clear DNS cache and reset TCP/IP settings

The following steps will reset all network settings for IPv6 and v4, so you must follow them. If you are ready for this, and you have information about all the settings (written down somewhere, for example), look in the “Start” menu command line and run it with administrator rights. Enter the following commands in the window that appears, confirming your entry by pressing Enter. After running each command, restart your computer and check the result.

1. ipconfig /flushdns
2. netsh winsock reset
3. netsh int ip reset c:\resetlog.txt - this command will completely reset all connections and you will have to configure them again!

Clearing the DNS cache using the command line

You have a direct connection to your provider

The option when your computer is connected directly to the provider, bypassing the router, is now becoming less and less common, as the number of network devices is steadily growing. But what to do if you have just such a connection? Eliminate possible problems with drivers as described above, and check that the connection settings are correct. Regarding the settings, the best option will contact technical support, since there are a lot of variations here.

Nothing helped at all

Maybe you're lucky and your ISP provides access using the new IPv6 protocol, the configuration of which requires knowledge of some subtleties. It should be noted that the expansion of the use of IPv6 is inevitable, since the address space of the previous version of the protocol, IPv4, has come to an end, and the global network is growing every day. Since your efforts have been wasted, and your network still hasn’t started working, then there is only one piece of advice - call a specialist. It is quite possible that the problem that has arisen is non-standard or that equipment replacement/repair is required to solve it.

There is Internet access, but the error remains

This situation may well exist. The reasons may be different - most often when connecting through a proxy server. However, there is only one solution. Press Win+R, enter gpedit.msc - this will take you to the local group policy editor. In the menu on the left, go through the following items: “Local Computer” Policy - Computer Configuration - Administrative Templates - System - Internet Communication Management - Internet Communication Settings. Now, on the right side of the window, find and enable “Disable active probing for network connection status indicator.” In Windows 10, this setting is called "Turn off active network connection health checks." Please note that now, even if there is truly no connection, the message will not appear.

Conclusion

This article collects the most common problems associated with the “Network without Internet access” error and suggests ways to solve it. We hope that the material was interesting to you and helped you overcome the difficulties you encountered.

Today I will look at a situation that users very often encounter operating systems Windows 7 And Windows 8. The essence of the problem is this: there is a connection to the network, but Network and Sharing Center writes that the Network without access to the Internet, there is about a clock next to the network icon in the tray Exclamation point. In fact, the Internet may even be accessible. There may be several reasons with different scenarios. Let's take a closer look at each of them.

But first things first, if you are connected via a modem, router or optical ONT terminal- I would advise reboot it. If, after rebooting the device, Internet access resumes, the problem is clearly in the router itself, its settings, or the provider’s network (this also happens). In this case, we reset the router with the reset button, configure it again and check. If still after some time a message appears that Network without Internet access- try another router to check.

1. WiFi network without Internet access

This is the most common situation. The reason for this problem is most often the following. The vast majority of users are not aware at all what is an IP address and believes that For Wi-Fi connections You just need to enter the network security key. In most cases, this may indeed be enough, but not always. If on WiFi router protocol disabled DHCP, then you can easily connect to the network, but here IP address your wireless adapter it will not work on a laptop, tablet or smartphone. Accordingly, you will not have access to the Internet, although the network is actually connected, but only partially.
By the way, this is also possible with a wired connection - the cable was plugged in, but the address was not received.
What to do? Register the IP address manually. To register IP in Windows 7 or Windows 8 you need to do the following:
Let's go to Control Panel and click on the icon Network and Sharing Center:

In the window that opens, click on the link Change adapter settings. A list of network adapters will open. Right-click on the network adapter through which we connect to the router and select the menu item Properties:

The network card properties window will open. Select an item Internet Protocol Version 4 (TCP/IPv4) and double-click on it with the left mouse button. This is where you need it register IP address, netmask, gateway and DNS address:

For most routers (except D-Link) the following should be suitable:
IP address — 192.168.1.2
mask — 255.255.255.0
Gateway — 192.168.1.1
primary DNS — 192.168.1.1
secondary DNS — 8.8.8.8
For D-Link routers:
IP address — 192.168.0.2
mask — 255.255.255.0
Gateway — 192.168.0.1
primary DNS — 192.168.0.1
secondary DNS — 8.8.8.8

2. There is Internet access, but it still says Network without Internet access

This problem is most often occurs when a computer connects to the Internet via a proxy server . That is, there is access to the Internet, but it is not direct, but through a server.
In this case, you can do the following:
Press the button Start select an item Execute(or press the key combination Win+R ) and in the window that opens we write:
gpedit.msc
it will be revealed to you Local Group Policy Editor.
Local Computer Policy → Computer configuration → Administrative Templates → System → Internet Communication Management → Internet communication settings and enable the parameter:
« Disable active probing for the network connection status indicator «

By this you disable active sensing . After this, the system will not check Windows network connection states to see if the computer is connected to the Internet or to a restricted network.

Many have encountered such a problem as the lack of Internet on a computer, laptop or other devices. In this case, the browser displays the message: “Web page is unavailable” or a similar message. Frequent culprits for this are: a failure on the provider's line, a malfunction of home equipment (router, network card, etc.) or incorrect settings. All this can be described in two words – “no Internet.” What should those who have a connection work, but web pages do not open?

This article talks about such situations and ways to solve this problem. In the last article I discussed the situation when .

The first step is to make sure that Internet access is really present and working correctly. As a rule, other programs that use the network work in this situation (Skype, ICQ, etc. are available).

But there are cases when they are not there, and it is not possible to install these applications. In this case, you can check the network operation using the command line. To do this, press the key combination Window + R and enter cmd in the window that appears. A terminal should appear in front of the user, where they enter the ping command (then you can try to enter the address of the Yandex website, for example, you will get - ping www.yandex.ru). If the described problem occurs, this command will display a message indicating that it is impossible to connect to the resource. But if you enter ping 8.8.8.8, a message about the successful status will appear.

The reasons for the problem when sites do not open can be different. This may be related:

• problems with the DNS service;
• influence of viruses and malware;
• incorrect proxy server settings;
• incorrect host file configuration ().

DNS Service Issues

A common culprit in situations where the browser does not open sites, but access to the Internet is not blocked, is the operation of the DNS server. This problem can be determined in the way described above, when it was necessary to open the command line and ping the address of any resource by domain name and ip.

Each site has its own location identification number, called an IP address. There are many different resources on the global web and they all have a unique address. In order not to torment a person’s memory, it was invented to create a service that, when entering the name of a site (for example, Yandex), could determine its IP address.

Sometimes situations happen when the provider's DNS server does not work or the network settings in the router or computer are lost. The reason why website pages do not open has been clarified; it remains to explain how to solve this problem.

There are two possible solutions. If the network settings are lost, then here you need to correct them to the correct ones and, if necessary, reboot the equipment. In the event of a DNS failure, you can change the settings on the network adapter. To do this, click “Start” - “Control Panel” - “Network and Internet” - “Network and Sharing Center” - “Change network adapter settings.” Here, on the “Connected to a local network” icon, right-click and select the “Property” option. Then select the TCP version 4 item and in the window that appears, select the “Use the following DNS addresses.” Below in the window enter 8.8.8.8 ( public Google DNS server) or 77.88.8.8 (Yandex public DNS). Then click the “Save” or “Apply” button.

To check the operation, you can open the command line (Window + R – cmd), then you need to check the connection (for example, with Yandex). Enter the command ping www.ya.ru. If you do the right thing, you will be able to see information about the server response time below.

Impact of viruses and malware

Also, the problem when sites do not open in the browser, but there is Internet access and DNS is working, may be associated with the influence of viruses and malware. In this case, it will help to solve the question “Why don’t pages open in the browser?” checking the system with specialized programs: AdwCleaner, Malwarebytes Anti-Malware Free, Zemana AntiMalware, etc. These utilities allow you to find malware that is causing problems with opening pages on the Internet.

Incorrect proxy server settings

Another reason why sites are not displayed in the browser may be changes or input of data about incorrect proxy server. At the same time, the computer is connected to the Internet and the connection works in all respects.
To correct this situation you need to go to your browser settings. To do this, go to the control panel, where you select the browser (or browser) properties item.

In the menu that opens, select the “Connections” tab and click on the “Network Settings” button.

Here, in the window that appears, they check all the parameters, and if they are not needed, simply erase all the information and select the automatic detection option.

After this, sites should display their pages in browsers.

Incorrect host file configuration

Also, the reason why pages of Internet resources may not open may be an incorrect configuration of the host file. This situation is unlikely, but still worth checking. The host file is designed to record domain names of sites and their IP addresses, but as a rule it is empty and sends all requests to the DNS server. Sometimes situations arise when a malicious program records some parameters and the browser becomes inoperable.

To check the file configuration, you need to go to the Windows system folder on drive C. Next System32\drivers\etc and open host with Notepad. As a rule, it has standard content as shown in the figure:

If, after the description of localhost (127.0.0.1), there are lines with information about any sites and their domain names, and the slash is not next to this data, then most likely the browser does not work properly because of them. To fix this situation, you just need to remove these lines and save the changes to the file. Then you need to restart your computer and try browsing the web again.

The situation when a computer is connected to a network, but sites are inaccessible to the user, occurs frequently. In the first place, this is a problem caused by failures on the ISP side when the DNS servers do not work. The second most common problem when Internet resource sites are unavailable is the impact of malware. In this case, it is recommended to have good anti-virus software and carry out preventive maintenance to detect viruses more often.

In contact with
