Home network without internet access windows 7. Unidentified network: the right way to fix the problem. Finding out the router address

When the Internet suddenly turns off, we, as a rule, begin to climb through the jungle of settings of the Windows operating system in order to somehow try to regain access to the precious information flow. Ultimately, we get into the settings of our Internet connection and see the message “IPv4 without access to the Internet or network.”

It's obvious that this information has something to do with the loss of the Internet, right? That’s right, and in this article we will tell you how to fix the “IPv4 without Internet access” problem. It can be solved in a huge number of different ways and we will consider them all.

However, first we need to specify possible reasons loss of the Internet and the appearance of this alarming message.

• Incorrect Internet connection settings, which could be set by the user himself or due to some changes in the system.
• Problems encountered on the user's provider side.
• Various errors and failures in the operating room Windows system, due to which access to the network may be blocked or connection settings may be reset.
• Malfunctions of the router(router).
• Exposure to any viruses or malware software(very rare cases).

Before we move on to consider the methods that can be used in this situation, there is one more thing to point out. Next to the message “IPv4 without network access” you can see a line that will tell you that IPv6 is also without Internet access.

Let's return to the problem with "IPv4 without network access" and the lack of Internet on your computer. Let's look at what you can try to do in this situation.

Errors and crashes in Windows work This is far from new to all users of this controversial operating system. It is possible that just one of these errors in some strange way was able to block your access to the Internet. To check this probability, simply reboot your system.

If, after rebooting the system, you have access to the Internet, and the line “IPv4 without network access” has changed, then this was just a one-time failure in the system. If the situation has not changed, then let's move on.

Method No. 2 Restart the router

A router is not the most reliable network equipment and sometimes it can easily start to malfunction, block access to the Internet, reduce the speed of the network connection and create other problems. If you suddenly lost internet and found “IPv4 without internet access”, then try resetting your router.

Resetting your router is quite simple: unplug the power from it, wait about thirty seconds, and then plug it back into power. Wait until your system detects the network connection and then check for the problem.

Method #3 Checking connection settings

If you recently changed something in the settings of your Internet connection, then this could be the reason for its disconnection and the “IPv4 without Internet access” status. The problem could have arisen due to some changes in the settings. For example, did you try to set some static addresses for IP or DNS?

Go to your connection settings and set everything to the same values ​​if they were previously changed. If you haven’t changed anything, then still go to the network connection settings( Win+R→ncpa.cpl→Properties→Information) and make sure everything is set correctly.

Method No. 4 Disabling the router

If resetting your router did not fix the "IPv4 without internet access" status and your connection settings are fine, then the problem may be with your router. Try connecting your computer to the network via a wired connection, i.e. without the presence of a router in combination.

So, if you connected a cable from the Internet to your computer and gained access to it, then the situation arose definitely because of the router, in which either the settings changed, which led to the “IPv4 without Internet access” state, or something happened to the router itself. device.

You can try restoring the router to factory settings in its parameters, which are available in most cases at 192.168.1.1 (the address for setting is indicated on the device box or on its body). If you have configured the router yourself, then you understand perfectly well what values ​​should be set there.

Method No. 5 Disabling/removing antivirus

Antivirus software is responsible for protecting your system from various malicious elements that are constantly trying to enter and harm it. Some antiviruses do their job well, but others, so to speak, go too far.

If you have a third-party antivirus installed on your system, try disabling it or even uninstalling it, as it could easily block your network connection. This happens rarely (mostly antiviruses block some files, even system ones, but not the connection), but it still happens.

If disabling/uninstalling the antivirus did not help return the Internet and “IPv4 without Internet access” still remains in place, then you can also try disabling Windows Defender (not relevant for Windows users 7), a system antivirus that should have been activated after removing third-party antivirus software.

Method #6 Disabling Windows Firewall

Another reason that could be behind “IPv4 without internet access” is Windows Firewall. This firewall may be blocking your network connection. Now we will try to disable your Firewall for a while and see what happens:

• Right-click on Start.
• Select "Control Panel".
• Select Windows Firewall.
• Click on "Turn on and off" Windows Firewall" on the left side of the window.
• Check the boxes that will disable the firewall for private and public networks.
• Confirm the changes.

Go to the "Details" window of your network connection, which can be found in the Network and Sharing Center and shared access, and see if protocol version 4 has Internet access. If not, then let's move on.

Method No. 7 Setting the DNS server address from Google

If you suddenly lost access to the Internet, then you can try to perform one specific, so to speak, trick, which sometimes helps to return your computer to the network. So, it consists in setting static addresses for the DNS server.

To do this, do the following:

• Press the key combination Windows+R.
• Write in the blank line ncpa.cpl and press Enter to open the Network Connections window.
• Find your network connection and double-click on it with the left mouse button.
• In the “Status” window, click on the “Properties” button.
• Select the Internet Protocol Version 4 (TCP/IPv4) component, and then click the Properties button.
• Set the following addresses for the DNS server:
  • Preferred DNS Server: 8.8.8.8.
  • Alternative DNS server: 8.8.4.4.
• Confirm the changes and close the window.

Having set static addresses for the DNS server instead of automatic ones, try looking at your Internet connection information again. Well, “IPv4 without network access” is still present. If yes, then we will now try to do something else that may help you regain access to the Internet.

Method No. 8 Setting a static IP address

The last point in our article will be advice on exhibiting static address IP for your connection, which, undoubtedly, also sometimes allows you to resolve the situation with the missing Internet and the problem in the form of “IPv4 without access to the network or the Internet.”

Here's what you need to do to set a static IP for your connection:

• Press the keys Windows+R.
• Write in line ncpa.cpl and press Enter.
• Double click on your Internet connection.
• Select your connection properties.
• Select Internet Protocol Version 4 (TCP/IPv4).

Here you will have to set certain values. First, you need to find out the address of your router (since this step applies to owners of wireless wired connection). For example, the most common address is 192.168.1.1., but it can be different. As mentioned above, it should be written on the router box or on its case. Once you know the address you need, follow these steps:

• In the IP address line you need to enter the router address, but only slightly modified. 192.168.1.1. →192.168.1.10. Add a zero to the end of the address.
• We do not enter anything into the mask line, because it will be set automatically.
• In the default gateway line we enter the already familiar address of your router, for example 192.168.1.1.

Save your Internet connection changes and then check for Internet connectivity and "IPv4 without network access" issues. How's it going? Still nothing. Well, in this case, you can point out a couple more not methods, but tips for this situation:

• It is possible that a virus has entered your system and has somehow managed to block your network connection. Check your system with an antivirus scanner.
• The problem with the lack of Internet and “IPv4 without Internet access” may lie on the side of your provider. Contact your providers and find out if there are any problems on their side.

The Internet is an integral part of our life. Lack of network is a serious problem for the user. You don't always have time to call your provider, but, fortunately, you can troubleshoot problems yourself. Below you will read about common causes of Internet problems and how to fix them.

Possible reasons for the lack of Internet on Windows 7

There are several reasons for the lack of Internet. Some of them relate to computer drivers and its equipment, others affect system errors and lack correct settings networks.

The most common reasons for lack of Internet:

• mechanical damage to the cable or ports;
• lack of a network card or its drivers;
• incorrect connection settings on the computer or router;
• presence of virus software.

Internet may also be absent due to debt on personal account or due to a line failure. Before you try to troubleshoot problems, check to see if these issues are causing them.

How to check network status

Among the problems with the Internet, we can highlight those that are most common and occur periodically for most users. Resolving them can be very simple. The first thing to do is check the network status.

You can do this in two ways:

In both cases, your network status will be described below your network icon.

Unidentified network without internet access

If the computer “sees” the network and connects to it, but does not gain access to the Internet, the network status will be called “Unidentified network. Without access to the Internet." What to do in this case?

Reboot the router

If you have a router installed, the first thing to do is reboot it. It may simply not have time to update the data, and because of this, access to the network will be lost. The reboot is performed in the following order:

1. First, the router is disconnected from the network. It is important to unplug the cord from the outlet, and not to reboot using the button on the equipment - you need to stop the flow of electricity for a while.
2. Then the router should be left turned off for 10–15 seconds.
3. After this, the router is connected back to the network and wait until the indicators on it light up.

After the indication appears on the router, you can check whether Internet access is available. Usually, after a reboot, the Internet appears within 7–10 seconds.

Checking network settings

Network settings are data that allows the computer to connect to the network distributed by the provider. These settings are issued by the company providing Internet access (usually they are specified in the service agreement). Sometimes the settings on your computer go wrong, and because of this, the device cannot connect to the Internet.

In order to check network settings, you need to open “Protocol Properties”. You can do it like this:

1. Go to “Control Panel” through the “Start” menu.
   "Control Panel" is located in the right "Start" menu
2. Select "Network and Internet".
   In order to find the desired section, you should select the “Category” viewing option in the right top corner screen
3. Open the Network and Sharing Center section.
   In the Network Control Center you can check the connection status, create a new network, and carry out almost any action with your Internet connection
4. On the left, find the “Change adapter settings” section.
   Find the section "Change adapter settings"
5. In the list of networks, select the one you need, right-click on it and find “Properties”. Only an administrator can open Properties.
   The desired network will be called “Local Area Connection” or “Ethernet”
6. In the list, find the item “Internet Protocol Version 4”, select it by pressing the left mouse button once. After this, the “Properties” button under the list is activated, you need to click on it.
   Selecting an item is done by clicking the left mouse button once. There is no need to uncheck the box next to the item.

When the window is open, you still need to understand what settings should be entered. There are three options:

Let's figure out what the IPoE and PPPoE protocols are, but we won't go into terminology. It is enough to understand what protocol is used on your communication line. To do this, just look at the network settings issued by the provider (specified in the contract).

The settings can be the following:

• password and login are used on the PPPoE protocol,
• IP address, subnet mask, gateway and DNS are used on IPoE.

If you are using PPPoE and you are connected directly, that is, you are not using a router, after checking the settings through the protocol properties, you need to recreate the network.

1. Return to Network and Sharing Center.
   This way only PPPoE connection is configured. To configure a wired IPoE connection, use the protocol properties
2. Open the “Create and configure a new connection” item.
   Switching items is done by single-clicking the left mouse button
3. Select "Create and Configure" new network" and click "Next".
   The selected item will be highlighted with a bright blue background
4. Click on the "High Speed" option.
   Waiting for search available connections may take a few minutes
5. If an error appears, select “Create the connection anyway.”
   This error appears quite often, but a connection can still be created
6. Next, you will need to enter the network settings, as well as the network name - this is the name of the connection. You can use the name of the provider company or something else.
   The connection name is its name, and the username and password are the network settings. It's worth noting that the password has nothing to do with the Wi-Fi key

After this, the network will be reconfigured, and you will only have to check whether you have access to the network.

Resetting TCP/IP Settings

Sometimes problems can be caused by internal system errors. TCP/IP - set network protocols, responsible for data transfer. You can reset it as follows:

Checking drivers

The reason for lack of access may be outdated drivers(usually this problem is associated with a recent operating system update). Let's check their condition.

In addition, by right-clicking on the driver name, you can select “Uninstall”, and then restart the computer. Then when you turn on the system will automatically install the missing driver.

If next to the driver icon there is Exclamation point, you will need to completely reinstall the drivers and check the functionality of the network card installed in the computer.

The default gateway is not available

Network diagnostics will help you detect the following problem. Right-click on your connection icon and select “Troubleshooting”.

If after system diagnostics a message appears about the gateway being unavailable, the following steps may help.

Prohibit disabling the network adapter to save energy

Sometimes the system turns off the network adapter - the device that allows you to connect to the Internet - to save power. Try disabling this option.

1. Find "Device Manager" through the search bar in the Start menu.
   Opening "Device Manager" through search is not the only way, but it is the most convenient
2. Expand the “Network Adapters” tab, select the one you need, and right-click on it.
   IN context menu click on “Properties”
3. Select "Properties" and open the "Power Management" tab.
   Changing these settings will help solve the problem of the Internet disconnecting after the computer goes into sleep mode
4. Uncheck the box next to “Allow the computer to turn off this device to save power” and save your data.
   After changing the settings, do not forget to save them by clicking on the “OK” button

Updating or reinstalling drivers

You can also update drivers through Device Manager: expand the Network Adapters tab, right-click on network driver and select "Update" or "Uninstall", then restart your computer.

If the action does not help, you can download drivers from their manufacturers' websites and install them yourself. Typically, manufacturers offer to download drivers from file format".exe", so to install you will only need to run the downloaded file and accept the agreement.

When connecting to the Internet through a router, error 651 occurs

This error occurs when trying to connect using the PPPoE protocol. It's rare, but it happens that users create new high speed connection while the provider uses the IPoE protocol. Therefore, first of all, make sure that you are using the PPPoE protocol.

After this, you will need to recreate the connection. The process is described in detail in the “Checking network settings” section (all you need to do is create a new connection through the “Network Control Center”). If this doesn't help, read on.

Disabling antivirus

Sometimes antivirus programs block access to the Internet. Often the solution to the problem is to disable the antivirus. Right-click its icon in the Control Panel and select Disable. Sometimes antiviruses block access to the network even in a “sleep” state, so you can try not only disabling, but also completely removing this software. If this action helps, please report the situation to antivirus technical support.

Problems with the router

The cause of the problems may be several problems related to the router:

• incorrectly connected cable;
• incorrectly entered settings.

First try the following:

1. Disconnect the router from the network.
2. Without connecting the router, unplug the network cable from it and plug it back into the WAN/INTERNET port, making sure that the plastic clip on the plug clicks when connected.
3. If the cable goes from the router to the computer, disconnect it from the LAN connector on the router itself and from the network card connector on the computer, and then connect it back.
4. Connect the router to the network.

If access does not appear, check the network settings entered on the router. In order to log into the router, you will need to enter “192.168.1.1” or “192.168.0.1” in any browser (in the address bar). Sometimes the address at which you can log into the router is different, so if you cannot log in through the specified addresses, check the information in the instructions.

Files cannot be downloaded from the Internet

It may also happen that Internet access is active, but files are not downloaded. This problem is usually associated not with the Internet itself, but with the computer and software.

What you can try:

• try to download a file from another source - perhaps you are unable to download something simply because the resource does not support downloading;
• try downloading through other browsers;
• check your computer for malware using any official antivirus.

Multimedia does not work on the Internet

It happens that the Internet works, but video or audio materials are not played. What to do in this case? First, check if the files downloaded to your computer are playable. Perhaps the cause of the problem lies directly in the computer's sound settings. If files are played from your computer, but not from the Internet, read on.

The first thing you need to do is understand why this problem occurs. It may be a browser error or lack of plugins. To get your computer working properly, do the following:

PPPoE diagnostics

Additionally, in order to find out the causes of errors when using PPPoE, you can use the Troubleshooting Center. Then the system will independently check for errors and offer possible solutions.

PPPoE (Point-to-Point Protocol over Ethernet) is a communication protocol over an Ethernet network that operates on a point-to-point basis and provides the user with a number of capabilities: encryption, authentication and data compression. It is necessary for the user authorization system, which makes it easier to track the time of provision and payment of network services.

Right-click the network connection icon and click the Diagnose Problems button. After this, an analysis will be performed, Windows will try to cope with the difficulties on its own, and then prompt you to perform several actions.

Error 619

Restart your computer and disable all security systems: antiviruses and Windows Firewall. The latter is disabled in the following way:

Error 633

There is only one solution:

1. Restart your computer.
2. Try connecting to the Internet again.
3. Create a new connection.

Error 638

Main causes:

• damage to the network cable;
• malfunction of drivers or network card;
• incorrect connection settings;
• problems with network equipment (router);
• presence of viruses on the computer.

First of all, do two things: check the integrity of the cable and the presence of indications on the router. Never neglect these steps when you have problems with the Internet, so as not to waste time trying to solve a problem caused by mechanical damage.

It is clear that if the cable is damaged, you need to call your provider. But if there is no indication on the router (which indicates that the device is de-energized), you should try reconnecting the router to a different outlet before replacing it.

After checking the functionality of the router and the integrity of the cable, check your computer for viruses with any antivirus program.

If the above does not help, recreate the network connection - check the correctness of the entered settings both on the router through its settings, and on the computer itself through the protocol properties. Both actions are described in detail in the previous paragraphs of the article.

Error 691

The only reason for error 691 to occur is an incorrectly entered password and login (network settings). Therefore, the first thing you need to do is recreate the connection. The process has already been described earlier - you need to go to the “Network Center”, select “Create a new connection” and then enter the correct network settings. After this, restart your computer and check your internet connection.

If the action does not help, report the problem to your provider. There may have been a line failure that caused the error.

Error 720

The easiest way to solve this problem is to reinstall the operating system. To do this, just download from the site Windows file operating system onto a disk (or purchase a disk in a store) and run it on the computer.

You can also try updating the TCP/IP protocol. The action is described above, but you can also perform a deeper operation by completely reinstalling the stack. Reinstalling the stack yourself is dangerous - you will have to work with system files, and their damage will affect the operation of the computer. Therefore, try simply updating the stack, and if the action does not help, contact your provider or professional technician for help.

Network cable not connected

If, when checking the connection status, a message appears that the network cable is not connected, the first thing to do is actually check that it is connected correctly and is not damaged. If possible, try using a different network cable.

Make sure the cable is connected correctly. On the router, the network cable must be connected to the WAN or INTERNET port, and the cable leading from the router to the computer must be connected to the LAN connector. There is usually only one port on a computer, so it will be difficult to make a mistake.

Next, check the status of the router (if you have one). Its indicators should light up as usual. If there is no indication, reconnect the router to another outlet, try resetting the settings on the router (using the “Reset” or “Reset” button) and entering them again. You should reset the settings only if you are confident that you can configure the router yourself.

Also check the status of your network adapter drivers and try updating them.

Video: checking the port on the network card and the WAN port on the router

Additional check of security settings

Security settings can also be to blame for many of these problems. This applies to the case when the PPPoE protocol is used. Therefore, if the proposed operations do not help solve your case, try checking your connection security settings.

1. Open the "Network Connections" section.
2. Right click on your connection.
3. Open the “Security” section and set the use of “Unsecure Password” in the list that opens.

These are the main ways to diagnose connections on Windows 7 and troubleshoot problems. Do not forget that the reason for the lack of Internet may be a simple debt or a breakdown on the line. If the methods described above do not help you, contact your provider so that technical staff can diagnose and solve the problem on their end.

In the PC IP address text field, you need to set the address of the router (router).

In the “Default gateway”, “DNS server” text field, enter the router’s internet protocol address (the same IP address of the router). At the end of everything, we confirm our actions by clicking on the “Ok” button.

Second way.

We need to go to the router settings interface and set the range of IP addresses assigned by the router to automatic mode. Make sure that it does not include the PC IP address that we specified manually.

Type URL – 192.168.1.1 in your browser, log in and the router’s admin panel will open in front of you.

There we need to find “Local Network” and go into the DHPC server settings.

In the “Starting address of the IP address pool” item, enter an arbitrary address that follows the PC address that we set manually (192.168.1.2). Finally, click on the “Apply” button.

I entered the following numbers - 192.168.1.5. Now the router automatically sets addresses for each device, starting with it.

If you do not know the IP address of the router, then take a look at it. As a rule, the manufacturer indicates at the bottom all the data about the device, including the IP address.

Today for many it is already an urgent need. Modern equipment And OS They become more and more intelligent, and the user less and less often has the 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 yellow triangle with an exclamation point.

Operating Microsoft systems, starting with Windows 7, 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 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.

Local connection Windows network 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 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). 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 entering your credentials correctly, 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 installed software that 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 open, where you need to find the “Network adapters” section, expand it and select 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, 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 would be to contact technical support, since there are a lot of variations.

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 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.

It's hard to imagine life without computers now. They help us in everything: in work, in school, teenagers even play games, making it their hobby and passion. But also every computer in our time should have something without which it is difficult to imagine a modern person. Yes, yes, we are talking about the Internet.

When we set up the Internet, questions may arise as to why the network or router is not working. Almost all users who set up the Internet on a router wonder where the error about the network comes from, which is impossible to identify. This is almost always what happens after reinstallation Windows.

Now we will clearly explain the reasons for such breakdowns and possible solutions to the situation.

Why does this problem occur?

Let's first understand how you use the Internet. If you have a cable connected to the computer directly, then this instruction will be for you.

So, the first reason is provider's fault. It happens that when setting up the Internet, the provider gives its data, which allows you to connect to its network from anywhere. But to gain access to such a point, you need to configure the Internet.

It may be configured incorrectly; this is an error on the part of the provider. Because regular users If they don't understand how to set it up, they can call a technician. As you know, half of the cases of Internet loss are associated with problems of the provider, and not the computer. It may already be configured, but the user does not know it.

Of course, if the problem happens specifically with the “Internet provider,” then you need to solve it only with your provider. How to do it? Everything is very simple. You need to dial the number of the service that provides Internet access.

Then, you explain the reason to the provider. Company employee willnoconsult you to help understand this problem. After this, the Internet will work as it should.

The second reason - incorrectly configured local network. It all depends on the IP address that is specified. It clearly acts in the direction specified by the user or the personal computer. IN

we need to configure it correctly local network. Often the IP Address is obtained by the ISP, but each ISP has its own rules. This means that you will have to configure it yourself.

What to do? Initially we go to "Change adapter settings". To find this section, you should open the Control Panel by selecting the “Network and Sharing Center” tab. New page opened, the next step is to select the “Local Area Connection” icon.

You are opening this section. Then right-click and select the “Properties” tab. It contains various data assigned to your connection.

Among all possible data, the goal becomes “Internet Protocol Version 4 TCP/IPv4”. Then, repeat the action with the right mouse button.

There may be different things here. Let's say you are using an IP Address, then you need to choose so that everything becomes the default. For this we choose “Obtain an IP Address automatically”. If this function is already installed, then the network is configured correctly and this is not the problem.

Once done, you need to click “Apply”, and then the “OK” button and exit.

Now let's talk about Wi-FI owners. Both problems that were listed above can also occur on a WI-FI router. However, there are a number of other problems.

The first problem is limited access. Don’t be scared, this is a private problem and it can be solved very quickly. in a simple way, namely by rebooting the router. This happens due to a network reboot.
The second problem is still the same problem, even after a reboot. And now a few reasons.

1. Incorrect network settings.
2. There is a problem with the drivers responsible for the Wi-Fi router.
3. The problem is with the router itself.

If you are a truly inexperienced user, then it is advisable for you to take the router to a specialist, who will be able to identify the cause of the router failure. But remember that this should only be done if you are sure that the problem is in the router. Even if everything is configured correctly and the provider is not at fault in this situation.

The IP address tends to be obtained automatically. In itself, the desired direction is set to obtain an Internet connection. And again we repeat that all providers provide access to the Internet differently. Most “Internet distributors” provide a clear IP Address for your network.

That's all. We hope that the solution to your problem is in the instructions provided to you. Do not rush to immediately call a specialist or cause panic.

Perhaps you have the most common problem that even the simplest user can solve. Follow the instructions and you will solve all problems related to the network on your personal computer. Best wishes to you!
