The wire doesn't work. What should I do if the network cable is not connected even though it is connected? Insert the network cable into another port on the router

Today for many it is already an urgent need. Modern equipment and operating systems are becoming more and more intelligent, and the user is less and less likely to need to do anything to configure them. 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.

Operating Microsoft systems, starting with Windows 7, they constantly monitor network connections, and as soon as 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, the new IPv6 protocol is becoming increasingly widespread, but its percentage is still very small, especially in home networks, so the main attention will be paid to 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 kind of 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

Cases are not so rare when 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 wireless router The cable will also be stretched. 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.

Connection via local network Windows 7 without internet access

It happens that 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 necessary one will not be crossed out with a red cross and its name is similar to “Local Area Connection” or “ Wireless connection"(in case of using Wi-Fi). Click on the desired connection right click mouse 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.

Properties of “Internet Protocol Version 4 (TCP/IPv4)”

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 indicate 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 excluding it. On your computer, go to Device Manager by pressing the Win+R keys, entering devmgmt.msc and clicking 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 ( Network address) 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, since the number network devices is growing steadily. 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 previous version 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 editor group policies. In the menu on the left, go through the items: Policy " Local Computer» - 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 we are all highly dependent on the Internet. And when it doesn’t work, panic immediately sets in, your heart sinks into your heels and life seems meaningless. It may be funny to you, but for some it really is.

The user is especially lost when the Internet is connected, but does not work. Today I will tell you why this happens and what to do if this happens to your network.

Why doesn't the Internet work?

If you are connected to the Internet, but it is not working, the first thing you need to do is find the cause of the problem. To do this, you need to restart all devices that are connected to the Internet. This means a router, a computer, etc. Most often, such a reboot completely solves all problems with the Internet, and it starts working properly. If, after rebooting the router and computer, you do not get the expected result, move on to the next “therapeutic” procedures.

Today, most people connect to the Internet by means of Wi-Fi router A. If you have the same, then you need to check whether the Internet access indicator on the router is on or not. For those users who use TP-Link router, the Internet access signal is marked with a globe icon. On other routers, this signal is most often signed “Internet”.

If the indicator is off, you need to check your router settings. If everything is fine with them, then we call the technical support of our provider and ask why there is no Internet, perhaps just a repair of the highway or network.

But, if the indicator is on, then there is a connection and the provider is not to blame. Check Internet access on other devices. It doesn’t matter what it will be - a phone, a tablet or another laptop. This way you can figure out which direction you should dig next to solve this problem. I’ll say right away that the case when a router is connected to the Internet, which is known to work well, but at the same time it does not distribute it to other devices, is considered a very rare case. The reason for this problem lies in the failure of the router. It's not difficult to fix this. You need to reset all settings to standard and reconfigure it again, remember that after the reset all settings will be lost and the Internet may not work until the router is configured correctly!

Cases often occur when only one device or computer cannot connect to the Internet using a router, but everyone else can easily access it. In this case, you need to look for the cause directly on this device.

If you are connected to mobile Internet via a USB modem or WiFi module connected to a USB port, then try disconnecting it and reconnecting it. If this doesn't help, try using a different port to connect. Perhaps reinstalling the driver will help you solve this problem.

Checking your Internet connection in Windows

In the case when the Internet is connected to your PC or laptop, but does not work, and at the same time you are one hundred percent sure that the reason for this is incorrect settings, then you need to follow a series of procedures that will quickly solve your problem.

You need to start reconfiguring by pinging any popular site. To do this, press the combination “Win ​​+ R”. This will bring up the “Run” window.

In the text input field, you need to enter the following “cmd” and click on “OK”. If you are not a fan of my site, you can write Google. After that, press enter and wait for the result. If everything is fine, the server will send you something like this:

If the response from the server contains the line “The connection check failed to find the nodepec-komp.com. Check the host name and try again,” then you need to type another command, for example “ping .8.8.8.8”. This is the IP address of the public DNS server from Google, which will always be available. If the computer has access to an external network, then the answer will be the same as in the picture above, but with different numbers after “answer from...”.

If a ping passes through an IP address, but does not open in the browser, then most often this indicates that there is an Internet connection, but the network does not work due to incorrect configuration network card, namely, the DNS server address is not written in them or is written incorrectly. I'll tell you how to fix this a little later.

If you observe a different response from the server, then you need to check access to the router. We will also check using ping. You can find out the router's IP address on a sticker that is glued to reverse side his body. Most often, the IP address of routers is “192.168.1.1” or “192.168.0.1”. The first address is registered on my router, so I received this answer:

If the router pings, but the Internet node does not, then most likely the reason lies again in the settings of the router or in the router itself.

But if the router is not available for server requests, then there is a reason to go into the settings of the network adapter on the computer. But, before doing this, disable your antivirus and firewall, if you have one. Sometimes it is these two “comrades” that cause problems with the Internet.

If after this the Internet does not work, although there is also a connection, press the key combination “Win ​​+ R” again, but now in the “open” field we write “ncpa.cpl.”.

If you have entered everything correctly, a network window will open. Windows connections. In it you need to find your active connection and right-click on it, then select “properties”. In the window that opens, look for the line “IP version 4 (TCP/IPv4)” and double-click on it to open the protocol parameters .

Check “Obtain an IP address automatically” and “Obtain a DNS server address automatically”. Click OK and check the result in the browser.

If this does not help, then check the box “Use the following addresses.” You need to register the IP address from the subnet of your router. If it has IP 192.168.0.1, then set the computer to 192.168.0.2. If the router uses 192.168.1.1 , then on the PC it will be 192.168.1.2. Mask 255.255.255.0. You must specify the router address as the gateway. You can also specify the server from Google as the preferred DNS server.

In any case, watch my video on speeding up the Internet, if you apply all the settings, the Internet should work.

Increasing Internet speed to the maximum!

I hope that at least one of the methods will definitely help you regain access to the Internet. If none of the options for solving the problem helped you, then you will have to call a specialist who will determine the true cause and solve the problem. But I’m sure it won’t come to that and you’ll fix everything yourself.

There are often situations when, after connecting a computer or laptop to the Internet using a network cable, the error “Network cable is not connected” appears. This is most likely not even an error, but simply the status of the network adapter, which can be observed in network connections.

It turns out that the computer does not respond to the connection in any way; the network cable is not connected, although it is connected to the computer and inserted into the network card connector. Icon on the notification panel with a red cross. Well, the Internet, of course, doesn’t work. This is what it looks like:

And most importantly, the cable is connected. From a router, modem, or directly from the provider’s equipment. This error can appear on both a PC and a laptop. It also doesn't matter which Windows is installed on your computer. Only in Windows 10 the message “Network cable not connected” will be next to the “Ethernet” adapter, and in Windows 7 – next to “Local Area Connection”. And in Windows XP, a pop-up window with this error still appears if you hover your mouse over the connection icon. The same thing often happens.

The same goes for the connection method. Some people have a network cable coming directly from their provider (for example, Rostelecom), while others use a modem, Wi-Fi router, or terminal.

What could be the problem?

There can be many reasons. We list the main ones:

• The network cable is incorrectly or not fully connected.
• The network cable is damaged. The contacts in the connector may have come loose (into which the network cable itself is crimped).
• Hardware problems with the router, modem, provider equipment. Or the network card itself in your laptop or PC has broken down.
• Problems with the network card settings. Most often, it cannot automatically determine the speed and duplex. I'll tell you about this in more detail.
• There are some problems with the network card driver.
• Viruses, firewalls, some programs. Yes, yes, they can also cause the “Network cable is not connected” error to appear.

How to find out the reason and what to do first?

• First, restart your computer, modem, router (if you have one).
• Disconnect the network cable and connect again. Also check the connection on the router (if the Internet is connected through it). Connect the cable to another LAN port. Pay attention to whether the LAN indicator on the router lights up after connecting the cable. You can see the instructions: .
• If possible, connect via a different cable.
• You can lightly move the network cable where it enters the connector. And at this moment look at the status of the network adapter on the computer. Perhaps the contacts are leaving there, and this way we can find out.
• If you have another PC or laptop, try connecting it. This way we can find out what's going on.
• If the Internet goes through a router, then try connecting the cable from the provider directly to the computer.

I would divide the solutions into software and hardware.

The network cable is not connected, although it is connected: solutions to the problem

1 I would try removing the network card from Device Manager. After a reboot it should recover automatically. Go to Device Manager (the easiest way to find it is through a search, or press the Win + R key combination and run the command devmgmt.msc).

Open the "network adapters" tab and find your network card. Depending on the manufacturer and driver, the name may be different. The name may contain "LAN". For example, on my laptop it is “Realtek PCIe GBE Family Controller”. By the way, pay attention to whether there is a yellow icon next to it. Right-click on it and select “Remove device”.

We confirm the deletion and restart the computer. Perhaps after a reboot everything will work and the computer will see the connected network cable.

2 Check the speed and duplex detection settings. In Device Manager, right-click on the network card (as I showed above) and select "Properties".

Next, go to the “Advanced” tab. In the list, find and select "Spread&Duplex". And in the drop-down menu on the left, set the value to "Auto Negotiation". But if you initially had this option installed there, then try setting a different value. For example: "100 Mbps Full Duplex". You can try different options. Don't forget to click Ok and restart your computer.

It just often happens that the network card cannot automatically detect speed and duplex.

3 Network card driver. You need to try reinstalling it. Download the driver from the website of the manufacturer of the card itself (LAN), laptop, or motherboard your computer and start the installation. You can look at the article on this topic:.

Other reasons why the computer does not respond to the connection of the network cable

1 Network card failure. However, in this case, you most likely will not see it in the device manager. But it happens in different ways. To find out, you need to connect another cable to it. Connect to another router or provider. Or connect other devices to the same cable. 2 Problems with the provider. For example: an employee of the provider was connecting the Internet to another subscriber, and accidentally disconnected your cable from the equipment, or the cable was broken somewhere in the entrance. Or maybe someone cut it on purpose. In such cases, the message “Network cable is not connected” will appear. You need to contact your provider's support. Just before doing this, it would be good to make sure that the problem is not in the network card of your computer. It also often happens that contacts disappear on the connector into which the network cable from the provider is crimped. You just need to do it again and correctly. Or call the experts. 3 Problem with the router. May be. But checking all this is very simple. Disconnect the Internet from the router (only if you don't have ADSL), and connect it directly to your computer. If the computer sees the network cable, then the problem is either in the router or in the cable with which you connect the PC to the router. You can also look at the article: . 4 The network cable is faulty. And this can happen. But, if we have a cable that we connect the computer to the router, then it is easy to check by connecting it to another device, or by connecting the cable from the provider directly to the computer’s network card.

Recently, we have described a lot of solutions to various problems related to connecting to . Now it’s time to pay a little attention to the problems that you may encounter when using a cable Internet connection. Although various errors and difficulties arise here much less often, sometimes you still have to deal with incomprehensible problems.

In today's article we will get acquainted with the main problems and ways to solve them that appear when connecting a computer to the Internet via a router. We will consider the case specifically when connecting through this device. If you are connected via a cable network directly from the provider, then this is a little different and today we are not touching on this topic.

This type of connection is often used if you need to organize Wi-Fi network, but at the same time, there are desktop computers, you need to connect the Internet to them. But such computers usually don’t have wireless adapter. Of course, there is a way out of this situation without unnecessary wiring - you need to purchase a special wifi adapter, connected via USB.

Troubleshooting problems with connecting to the Internet via a network cable from a router

But for now we will take a closer look at the topic of our article. If, after connecting your computer with a cable to the router, the Internet does not appear, then you need to look at the following important questions:

• Try connecting another PC to the same cable. Will it work?
• Connect cable internet to a PC without a router. Will it work now?
• The router should light up led indicator LAN
• You need to look at the local network connection status. What does it show? It may not show any signs of activity at all when the cable is connected. Or it can begin identifying the connection.

Depending on the answers to these questions, we will determine the cause of the problem.

The computer does not see the connected LAN cable

In this case, when connecting the network cable, no messages or activity appears from the latter. The network connections icon is crossed out in red, and if you hover over it, the message “No connection” will appear. Everything looks exactly the same as if the cable was not connected at all.

Here the problem can be hidden in three places: either in the router or computer, or the cause may be a damaged cable. First, let's check the health of the computer itself.

Connect the cable to it without a router, directly. If the network connection status has changed, then apparently the PC has nothing to do with it. Or you can check it the other way around by connecting the cable through the router to another PC.

If the computer continues not to see the cables connected to it, regardless of their sources, then most likely we have problems with the network card. If necessary, you can always purchase and install another one, especially since it is not expensive. But first, make sure that your computer actually has a network card driver. You can check this by going to Device Manager and expanding the list of network adapters. Make sure your card is there. Its name may differ from what is shown in the figure below.

In some cases, the network card may be displayed, but there will be a yellow exclamation mark next to it. This indicates that the network card may not work correctly. You need to try reinstalling the driver for this device. Download it from the manufacturer's official website and install it manually.

Sometimes you may encounter that the connector for connecting the network cable on the router is burnt out or somehow damaged. Routers often have several of these connectors, so try connecting the cable to others. Maybe everything will work.

The problem may also be in the router itself; this can be checked by connecting it to several different computers. If in all cases the connection to the Internet does not appear, then it is obvious that the culprit is the router. It may not necessarily be physical malfunction, maybe something is just wrong in the settings. Reset and restart it, then check again.

In this case, you need to be sure that the cable itself is in good condition. It can also break somewhere or have bad contact. You can look for another one and check it. But the problem may be related to the settings on the computer. In some cases, the local network may be disabled on the PC.

Here you need, through the Control Panel, go to the Networks and Internet section, open Network Connections. If the status “Disabled” appears under the local network connection icon, right-click on it and enable it.

Usually one of these recommendations will definitely help.

The network is constantly being identified, or it is not recognized at all

Now let's see what can be done if the computer notices the connection of the network cable, but still cannot connect to the Internet. For example, we connected the cable and the network status “Identification” appeared. Everything seems to be cool and the network should appear soon! But time passes and nothing changes.

Another case is when the computer does not recognize the network and displays the corresponding status.

Typically, such errors are directly related to obtaining an IP address. May be disabled on your computer automatic detection network settings, or a specific static IP address is recorded instead. For example, it may remain from a previous connection. But for the router it is not correct and you will not be able to establish a connection to the Internet. DHCP may not work on the router itself, which automatically issues addresses to all devices. Again, you need to go into settings and enable this feature, or manually enter all the necessary addresses on your computer.

To enable automatic detection of IP and DNS addresses, you need to go to the Control Panel and open the Networks and Internet section there. Next we go to network connections. There is another way to get there, do it as shown in the picture below.

Next, right-click on Local Network Connection and open its properties. Then follow the steps shown in this figure.

Unplug your network cable from your computer and connect it again. After this, the Internet should start working normally.

By following the same paths, in the same settings, you can manually specify IP addresses. Only in this case, activate Use the following IP. We determine which address needs to be entered using the address at which the router settings are available. For example, the router settings are 192.168.1.1, which means the address should be entered something like 192.168.1.60. We just take the address and change the last number to another, for example 60.

DNS can also be specified manually; they will look like this: 8.8.8.8 and 8.8.4.4.

No internet access (yellow triangle with exclamation point)

Or how it is displayed in the status “Without Internet access”.

This message says that the cable is connected and everything is working successfully, including the router, but there is no access to the Internet. Perhaps the router itself is not connected to the network, or has incorrect settings. In some cases, problems may arise from the provider, so you can contact him and clarify.

One of common mistakes problems that arise when connecting a computer to the Internet is the appearance of an error message that the network cable is not connected and the Internet is not available, although in fact it is connected and may have even worked some time ago. Moreover, there may even be Internet access, but the error remains. What to do in this situation and how to restore communication?

Reasons for the error

There can be many reasons - I propose dividing them into two groups

• Related to problems outside the computer
• Or with the PC itself or Windows settings

The network cable is not connected - what to check first?

Problems with the router

Requires a separate discussion possible errors at setting up wifi router, if the computer is connected to the Internet not directly, but through it. This topic is extensive, we have already touched on it several times on the blog. In particular, the problem when , or . But within the framework of this article I can only give some general advice:

The network cable is not connected or the network is unidentified on the computer

Before you figure it out possible reasons and ways to fix them related to system settings, I note that the error message may also look like “ Unidentified network" or "Without Internet access."

Let's go through the main methods that will 99% correct our situation, if the problem is still due to the connection of the equipment installed on the computer in combination with Windows settings - we will leave out the possible banal failure of the network card.

1. device Manager

   I will show on Windows 10 - first, let’s try to go to “Start (right click) - Device Manager”

   

   Open the “Network adapters” branch and find the line “Realtek PCIe GBE Family Controller”.

   
   

   Right-click on it and select “Remove device” in the new window.

   
   

   Then we reboot the computer - when loading operating system it will show up again in the system.

   If after this the Internet does not work, then we try to go to “Properties” in the same way.

   
   

   Here we go to the “Advanced” tab - before our eyes we will see a long list of different values, among which you need to find “Speed ​​& Duplex”. Here, the right drop-down list should contain the value “Auto Negotiation”.

   

   If this is the case for you, but the Internet does not work, try playing with the selection of other values

   

2. Finally, the last thing that could be causing the “Network cable is not connected” error is a driver malfunction.

   In general, it is recommended to always have latest version drivers for all PC components. Download from the manufacturer’s official website and update the driver for your network card. It’s even easier to use a ready-made kit - I talked about this in detail in this article.

Thank you! Did not help
