Unidentified network on home windows 7. Local area connection: unidentified network

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 the lack of correct network settings.

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.

The Internet may also be unavailable due to a debt on a 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?

The computer “sees” the network and connects to it, but does not gain access to the Internet

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 the 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 upper right corner of the 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 a new network" and click "Next".
   The selected item will be highlighted with a bright blue background
4. Click on the "High Speed" option.
   It may take several minutes to wait while searching for available connections
5. If an error appears, select “Create the connection anyway.”
   This error appears quite often, but the 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 is a set of network protocols responsible for data transfer. You can reset it as follows:

Checking drivers

The reason for the lack of access may be outdated drivers (usually this problem is associated with a recent update of the operating system). 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.

After removing the drivers and restarting the computer, the system will automatically install the appropriate drivers

If there is an exclamation mark next to the driver icon, 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”.

By right-clicking on the icon you can open the “Network and Sharing Center”

If you receive a message about the gateway being unavailable after performing a system diagnostic, 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 the 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 the 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 in an “.exe” file format, so to install, you 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 is rare, but it happens that users create a new high-speed connection while the provider is using 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 the operating system file to disk from the Windows website (or purchase the disk in the store) and run it on your 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.

The WAN or INTERNET port is used to connect a network cable to the router, and the LAN ports are used to route cables to computers

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.

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.

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

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

1. WiFi network without Internet access

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

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

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

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

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

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

The Internet is capturing more and more users around the world. The network can be accessed through computers, tablets, smartphones if there is a Wi-Fi network or a direct connection cable. However, when operating computers and laptops, an error such as “Unidentified network without Internet access” or “Restricted” (depending on the version of Windows) may occur. It's easy to fix, but first you need to understand the cause of the problem.

What does the error with the text “Unidentified network without Internet access” mean?

An error like “Unidentified network without Internet access” or “Restricted” (for later operating systems Windows 8, 8.1, 10) means that the computer sees a connection to the network, but for some reason this network does not have access to the Internet. There are not many reasons, since the error indicates that everything is fine with the computer’s hardware, the network card and cord are not damaged, and the problem lies directly in the connection.

“Unidentified network without Internet access” indicates the impossibility of connecting the network to the global web

The reasons can be divided into three categories:

• problems on the part of the provider - the service provider carries out technical work on its servers or closes the flow of traffic to the address if the funds on the personal balance have run out;
• error with the router - the settings have gone wrong or the device has simply overheated;
• software errors in the computer:
  • IP address settings are lost;
  • DNS cache is dirty;
  • Internet protocol settings were violated;
  • There were minor problems with Windows services.

How to find and fix the cause of the error in Windows XP, 7 or 10

Restart your computer before troubleshooting. It is quite possible that one of the services that is responsible for network protocols has failed, and you can restart all services by simply rebooting the PC. And if this procedure did not help, we begin to delve into the reasons in more detail.

If the error occurs on the provider side

We follow the chain of connection to the Internet. The first link is the provider. You need to call the service provider's support line, give your address and report that there has been no access to the Internet for some time. Provider employees are required to:

If the problem is with the Wi-Fi router

The router can also cause the lack of Internet. To make sure of this, you need to try connecting another computer, laptop or smartphone to the network. If you cannot open a website or instant messenger on all connected devices, then the problem is clearly in the router.

Unfortunately, fixing technical problems with your router is extremely difficult. You must contact the service center or directly to the provider if the device was provided by them. But if a failure occurs in the software part, there are two main methods for returning the router to working condition at home:

1. Disconnect the device from power for a while. Some experts say that 30 seconds is enough, others advise increasing the period to 15 minutes. In any case, it is important that the router is not exposed to static electricity for some time. Afterwards it can be returned to working condition.
2. Reset settings to factory defaults. There is a special button on the device body for this procedure. It may be called Reset or WPS. You must press this button and do not release it for 10–15 seconds. After this, all changes in the web admin will be returned to their original state, the router will literally be “as good as new.”

If the problem is in the computer software

The last link is the computer itself. For each sphere to work, several services, protocols, and correct settings are always required (the user has access to many, so sometimes we ourselves don’t know what we are disabling). Incorrect intervention or an accidental failure can lead to a chain reaction and access to the Internet will simply be cut off. Therefore, when you make changes to certain system parameters, always remember what exactly you changed and in what place, so that you can correct what you have done.

Correcting the situation with the error “Unidentified network without Internet access” on your computer involves making changes to the IPv4 protocol or resetting the settings and cache of all system Internet protocols.

Setting an automatic IP address and DNS server

First of all, you need to check whether your computer has automatic IP address and DNS server settings.

1. On the keyboard, simultaneously press the Win and R keys. In the utility that opens, enter the command control.exe /name Microsoft.NetworkandSharingCenter and click “OK”.

   Through the execution utility, open the “Network and Sharing Center”

2. In the interface that opens, we find a connection that does not have access to the Internet and click the link opposite. In the “Status” window of the network, click the “Properties” button.

   Open the “Status” of the problematic network

3. In the “Properties” window of the network, select the line called “IPv4 Protocol” and press the “Properties” button again.
4. We move the toggle switches to the automatic position and save the changes using the “OK” button in all interfaces.

   In the network properties, set automatic parameters for the IP address and DNS server

5. Reboot the PC.

The DNS server fields can be filled as 8.8.8.8 and 8.8.4.4 in the corresponding fields.

Resetting Internet Protocols

Often network problems arise due to network protocols in Windows. Some may change under the influence of the user or viruses, others may become cluttered (for example, the DNS cache). All this can lead to problems with your Internet connection. A possible solution may be to reset all protocols, DNS cache, and proxy settings.

Video: how to reset network settings

Fixing the “Unidentified network without Internet access” error is simple; you just need to try troubleshooting methods one by one, or just wait if the problem is on the provider’s side.

When, during the next attempt to connect to the Internet, the computer writes “unidentified network” and refuses to let the user into the vastness of the virtual world, many “users” experience a “creative crisis”. Naturally, many “thorny” questions immediately arise: what kind of unidentified network is this, why the ethernet connection is limited and what, exactly, to do in such a situation - which we will try to answer in this article.

So, why does the “unidentified network without internet access” error occur?

Unidentified network windows 7: causes of the problem

It should be noted right away that an unidentified Windows network can arise either as a result of incorrect router settings or an “internal” failure of the operating system.

So, among the most “popular” causes of the problem, highlight:

• - Settings failure on network equipment.

• - Damage to the network cable.

Of course, if the signal from the router does not reach the computer, then the latter will be without access to the Internet. Carefully check the integrity of the cable along the entire “path” of the signal: perhaps the twisted pair was accidentally “broken” by an interior door or crushed under a sofa.

• - Problems on the part of the provider.

However, before calling technical support, it is worth eliminating all “internal” causes of the problem.

Separately, it is worth mentioning the “unidentified network” message from the Rostelecom operator. So, with a direct connection to the Internet (when the cable provided by the provider is connected directly to the computer’s network card) - this is the norm. At the same time, the subscriber does not have any restrictions on access to the Internet, and he receives in full his megabits paid according to the tariff plan.

• - Incorrect network adapter settings.

We talked about network card settings in detail in articles and.

Here we note only one important nuance: check that automatic data reception is set in the properties of the network adapter.

• - Internal protocol errors.

You can assume such a reason when, after a restart, the computer displays an unidentified network.

To “defeat” this problem, you need to go to the command line (start - all programs - standard - command line) and write netsh int ip reset resetlog.txt there.

After entering the “magic” combination, press the “Enter” key and patiently wait until the computer restarts.

• - Network card malfunction.

If an unidentified Windows 10 (7 or XP) network appears after reinstalling the system, it is likely that the cause of the problem is a “crookedly” installed network driver. Uninstall the program through the “Control Panel” and install the “fresh” version of the software from the official website of the network card developer.

How to remove an unidentified network in Windows XP?

In general, the procedure for “deleting” an unknown network here is similar to Windows 7, 8 and Windows 10.

However, here special attention should be paid to setting up Realtack Controllera (you can go to this section through the menu - control panel - network connections).

It is important to set the network address property correctly here.

If none of the listed options solved the “unknown network” problem, you should still call the provider’s technical support: there may be problems “on the line” or this service is blocked for you.

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

Microsoft operating systems, starting with Windows 7, constantly monitor network connections, and as soon as the global network is unavailable, they immediately report it. 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 the 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 happens to you for no apparent reason, 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 there will also be a cable running to the wireless router. Check the integrity of all wiring - are there any strong kinks anywhere, are all plugs firmly inserted into the sockets and are they inserted where they really need to be. Provided that no problem is found here, we move on to the next step.

Connecting via local network Windows 7 without access to the Internet

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

Checking your computer settings

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

Setting up a local network connection in Windows 7

Finding out the router address

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

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 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 on the installation disk will do. 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 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.

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 indicated 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 of the previous version of the protocol, IPv4, has come to an end, and the global network is growing every day. Since your efforts have been wasted, and your network still hasn’t started working, then there is only one piece of advice - call a specialist. It is quite possible that the problem that has arisen is non-standard or that equipment replacement/repair is required to solve it.

There is Internet access, but the error remains

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