The Internet does not work via the network cable from the router. How to fix the problem: unidentified network without Internet access? LAN Connection Identification

The error itself "Unidentified network. No Internet access" is well known from previous Windows versions. IN new Windows 10 error “Unidentified network” looks a little different, but the problem itself and solutions remain the same. The appearance of this error indicates that there are problems with your Internet connection. When there is no connection for some reason. In this case, it doesn’t matter at all whether you have a laptop, a desktop computer, or even a tablet.

This error may appear when connecting via Wi-Fi, via a router, or when connecting via network cable (directly from the provider, or through a router). In both cases, there will be a yellow icon next to the Internet connection icon in the notification bar Exclamation point. And in network connections, next to the adapter through which you are connected to the Internet there will be an inscription “Unidentified network”.

Let's see how it all looks in practice.

When connected via cable (Ethernet)

If you encounter this problem when you are connected to the Internet via cable, then there will be an error in the connection status window "Unidentified network. No internet connection". Well, there’s a yellow icon next to the Internet connection icon. And next to the “Ethernet” adapter there will also be a message about an unidentified network.

If connected via Wi-Fi

In this case, the error will be "No internet connection, secure". The wireless adapter will have the status "Unidentified Network". And next to the "Wi-Fi" icon there will be a yellow exclamation mark.

When connection via Wi-Fi router. Including via cable.
And when the Internet is connected directly to the computer via a network cable. From the Internet provider.

It seems to me that this error is most often encountered when connecting via a network cable. Via an Ethernet adapter.

Simple solutions to the "Unidentified network" error in Windows 10

Let's first look at simple and basic solutions. Perhaps these tips will help fix the problem with Internet access. And you won't have to figure out more complex solutions.

Resetting network settings

I thought about it and decided to advise the first thing to do a reset network settings. This method very often helps solve various problems with Internet connection. In Windows 10, doing a network reset is very easy. In the settings, in the "Network and Internet" section there is a separate item. Just click on “Reset network”, then on the “Reset now” button and confirm.

I described this process in more detail in a separate article:.

There is a chance that after restarting the computer the Internet will work.

You can also reset TCP/IP settings via command line by running the following commands:

netsh int ip reset

ipconfig /release

But I don't see much point in this. If you have Windows 10, then it is better to reset the network, as I showed above.

Verifiable TCP/IP settings

The “Unidentified network” error itself indicates that the system was unable to obtain an IP address from the router or ISP equipment. Perhaps the problem is in the IP settings for the IPv4 protocol in the properties of our Internet connection. If some static parameters are already specified there, then it is quite possible that they were set incorrectly. You can try setting automatic IP acquisition. Or register static settings (if the connection is via a router, or your provider issues a static IP).

This error can also be caused by problems with the DHCP server on the router. (whose task is to distribute IP addresses). Therefore, reboot your router.

One more thing: you probably noticed that after disconnecting and reconnecting the cable, or reconnecting to the Wi-Fi network, the connection remains in the “Identification” status for a long time. This is nothing more than an attempt to obtain an IP address to connect.

Open Network and Sharing Center shared access" and "Changing adapter settings."

If the connection is via Wi-Fi, then open the properties of the “Wireless Network” adapter.
If via a network cable, then “Ethernet”.

Near the problematic adapter there will most likely be the inscription “Unidentified network”. Right-click on it and select "Properties".

Highlight "IP Version 4 (TCP/IPv4)" and click the "Properties" button. Another window will open in which you can set the necessary parameters for of this connection. do this:

If this does not help, then it is better to set the automatic receipt of addresses back. Or register the addresses that were originally specified there.

Changing the network address with the error "Unidentified network. There is no Internet connection"

In some cases, changing the MAC address of the adapter through which we connect to the Internet can help.

To do this, you need to go to the device manager. You can find it and run it through the search. Or by specifying the command devmgmt.msc in the Run window that appears after pressing the Win + R key combination.

In the manager, open the "Network Adapters" tab, right-click on the adapter through which you connect to the Internet, and select "Properties".

Go to the "Advanced" tab. Select " Network address" (Network Address). And by setting the switch next to the empty field, we write a new address of 12 characters there. You can only use numbers or letters from A to F. It looks something like this:

Click "Ok" and restart the computer.

Remove the adapter, update the Ethernet and Wi-Fi adapter drivers

Honestly, I have not seen a case where the network adapter driver was to blame for solving such problems with the lack of Internet connection in Windows 10. But anything is possible. Therefore, I would advise you to first try removing the adapter so that it is reinstalled in the system.

To do this, in Device Manager, just right-click on the adapter, when connecting through which the “Unidentified network” error appears, and select “Delete”. If you have problems with Wi-Fi connection, then you need to remove the driver whose name is “Wi-Fi” or “Wireless”. I have the driver shown in the screenshot below network card"Ethernet".

After this, restart your PC or laptop. The system should again detect and install the adapter driver that we removed. I wrote about this in an article. There I also gave other advice on this topic.

You can try reinstalling the network adapter driver that is causing problems. You need to download the driver for your laptop model or adapter from the official website and start installing it.

There is a separate article on this topic:. And separately for the network card driver (LAN): .

I will try to supplement the article with new solutions that can resolve the error with an unidentified Ethernet network or Wi-Fi adapter in Windows 10. If you have any information on this problem, please share it in the comments. There you can leave your questions on the topic of the article.

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.

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 may be problems with the provider, incorrect setting equipment from the user or malfunctions 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 lines are damaged, some technical work is being carried out, 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 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 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 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). Press required connection right-click 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 eliminating 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 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), find the command line in the Start menu 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.

ipconfig /flushdns
netsh winsock reset
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 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 sensing for status indicator” network connection" 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.

IN Lately 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 these 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 LAN LED on the router should be lit.
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. This may not necessarily be a physical malfunction, perhaps just something in the settings is messed up. 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. Automatic detection of network settings may be disabled on the computer, or a specific static IP address may be 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 to settings and enable this feature, or manually enter everything required 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.

Often for many users personal computers You may have a problem with correctly determining the network connection. In this case, the device will notify the owner of any problems that have arisen. There may be 2 notifications: a red cross on the Windows network icon (if there is no link with the device) and an exclamation mark (unknown Windows network without Internet access). This article discusses why problems arise with the second option of alerts and how to resolve them.

Problems on the provider side

If you did not change the system settings or Wi-Fi router, did not replace the motherboard and network card, or reinstalled Windows, it is unlikely that any problems could arise on your side.

It may well be that everything is fine with your computer and router, the network is there and working correctly, but the provider this moment does not provide you with Internet.

Firstly, perhaps you simply did not pay for the service - in this case, a notification “ unidentified network without access to the Internet." Try contacting technical support provider and ask whether the service has been suspended, and whether scheduled or unscheduled maintenance is currently being carried out.
Perhaps there is a simple way to solve the problem and the operator will tell you about it. Otherwise, he will be able to leave a request to check the integrity of your line.

Obtaining an IP Address

Another reason for the “unidentified network without Internet access” error is conflicts in obtaining an IP address. It's often on new ones operating systems Windows or appears after reconfiguring your home router.

Let's look at the main possible reasons why this could be:

The Wi-Fi Router distributes dynamic IP addresses, but a static one is installed on the computer.
The router does not have a DHCP server, so it cannot assign a dynamic address to the computer, and this type of receiving is specified in the system.
The server or router has security systems and they block your IP as unverified. This is a common occurrence when connecting via Wi-Fi in large companies and offices. In this case, you must contact your system administrator.
The IP selected in Windows matches another one already active on the network, or is outside the area supported by the router.

Windows network settings

To resolve network conflicts, you will need to go to Windows settings. To do this, follow the instructions provided:

Depending on the settings of your Wi-Fi router, you will either need to check the boxes next to “Obtain IP automatically” and “Obtain DNS automatically”, or enter the correct static addresses.
The following settings will work for most routers:

IP – “192.168.0.*” or “192.168.1.*”, where “*” is any number from 2 to 254.
Mask – “255.255.255.0”.
The default gateway is the address of your Wi-Fi router. It can be found on a label glued to the device body. This is usually "192.168.1.1" or "192.168.0.1".
DNS – you also need to enter your router in this field.
Alternative DNS – you can leave it blank or enter a popular DNS server from Google– “8.8.8.8”.

After that, return to the local network properties and click on the “Disconnect” button. After that, in the “Adapter Settings”, double-click on the Internet icon to turn it back on. You can also disconnect and connect the patch cord that goes to your computer.

Problems with the DHCP server

If your router distributes addresses automatically via Wi-Fi or a wired connection, there may be some problem with the DCCP server. In this case, resetting and updating the server configuration will help. To do this, open in administrator mode Windows console and enter 2 commands in turn: “ipconfig /release” and “ipconfig /renew”.

It usually occurs when you change your home modem or move to a new place of residence. As they often say in such cases, everything seemed to work and nothing was changed. But nevertheless, there are some nuances here.

Now we will talk only about one of the most common causes of this problem and only one simple solution. After all, this is how the author has always managed to access the Internet.

So let's start from the beginning. And first of all we will look at Wi-Fi. If, when connecting to the modem using this method, you receive this message in the “Network and Sharing Center”:

This means that the first thing you need to do is perform one simple operation. Next, all settings will be shown on Windows example 10, but in older systems everything is done by analogy. The main thing is to understand the general essence.

Right-click on “Start” and select the “Network Connections” section:

Then you need to select the wireless network adapter and right-click on it again. In the menu that opens, select the “Properties” line:

In the next step, we follow the path “IP version 4-Properties”:

And check that the “Obtain an IP address automatically” option is activated in all points:

After this, in theory, the annoying message “Unidentified network without Internet access” should disappear. So let's check if this is actually true. After all, you can only trust your own eyes.

To do this, click on the icon in the system tray wireless connection and select "Network and Sharing Center":

And here you go, not a trace remains of the hateful message:

Now you can safely use the Internet. By the way, the IP address settings of the network card can also be changed through the “Change adapter settings” item. Remember this point, as we will return to it later.

Okay, but let's now talk about a situation where after the above settings the situation has not changed. In this case, we can assume that the DHCP server function is simply disabled in your home modem.

After all, it is she who is responsible for automatically distributing IP addresses to devices connecting to it. And here it must be said that setting it up for each router model will be individual.

Using the article as an example, this case looks like this:

So, dear ladies and gentlemen, enable this option for yourself and you will be happy. Now let's move on to setting up a wired network card. How to configure it correctly if there is no access to the Internet?

The most interesting thing is that in this case you need to do the opposite. That is, the values of IP addresses must be set manually. This is done as follows. Select the wired network adapter and go to its properties:
