No network connection. How to Diagnose and Fix Internet Connection Problems

Read troubleshooting guide for various problems network connections on Windows. Five universal ways. You may also want to check out our earlier article, A Guide to Troubleshooting Internet Connection Problems, in which we tried to cover a different range of Internet connection problems.

The essence of the problem

The concept of the Internet today has become very firmly established in our lives, and most people use it fully and everywhere. On the Internet, people are trained and gain knowledge; visit exhibitions and libraries; communicate through social networks and video communicators ( "Skype", "Viber" etc.); develop projects; transmit and receive information, letters and documents; learn and share news; watch movies and listen to music and much more. It is not surprising that the ability to access the Internet is supported by many various devices: personal computers, laptops, smartphones, tablets. All of them provide connection to the Internet in different ways: using a cable, via « Wi-Fi connections» or using mobile access capabilities through the services of mobile operators.

Sometimes devices are combined different ways connection to the Internet, for example, a laptop can be connected directly with a cable and using "Wi-Fi connections", the smartphone has "Wi-Fi" connection and mobile internet. But sometimes there are various connection problems such as no connection, limited connection, inability to access network drives or browse websites, etc. In such a case, you face problems connecting to the Internet or local network V "Windows". Or you receive error notifications containing such error codes. It happens that the connection does not work "Ethernet" or function "Wi-Fi" your laptop, or there was a problem with the connection settings. This situation is very upsetting and you try to find a way out of the situation on your own.

In this article, we will try to tell you about various Internet connection problems and how to resolve them for different types of network and Internet connections in the operating system "Windows". Most of the methods given in this article will work in all versions "Windows", but some of them will only be available for certain operating systems.

We will try to list the main possible solutions to fix network and internet connection related problems in "Windows". You should try these solutions one by one. And one of them may be able to help you troubleshoot problems.

METHOD 1: Run the built-in network troubleshooter

The first thing you should try to fix network connection problems is to activate the built-in troubleshooting tool and network problems V "Windows". This tool automatically diagnoses and finds the cause of the problem, and tries to fix the problem if possible.

To run the troubleshooter, click right click mouse icon "Net" located in the notification area on "Taskbars" and select section from the pop-up menu.

The problem detection process will start, the result of which you will see in the window.

Wait a few seconds, during which time the tool will diagnose networks, perform troubleshooting, check Internet connectivity, find the cause of the problem and show ways to fix it.

In most cases, this built-in problem detection tool will completely fix the problem and restore your Internet connection. As a last resort, he will point out to you the existing malfunction and suggest a solution to it.

METHOD 2: Use the function "Network reset"(Windows 10 only)

Sometimes the built-in troubleshooter (described in Method 1) cannot resolve connection issues. Then you need to manually reset your network connection settings and network adapters.

And if you are using an operating system "Windows 10", you can use the built-in function "Network reset" to automatically reset network adapters and network components. This feature first removes all installed network adapters and then reinstalls them. It also installs other network components in initial settings.

Function "Network reset" was added to "Windows 10" to the update version "Windows 10 Anniversary Update"(version 1607). This feature was designed to help users resolve connection issues after upgrading their operating system to "Windows 10" With previous version "Windows". It can also do a great job of helping users troubleshoot network connection issues they may encounter later in their future use.

To access the function "Network reset", you just need to follow these steps:

METHOD 3: Assign IP address and DNS manually

After updating previous versions "Windows" to the latest operating system "Windows 10", you may have a problem accessing the Internet. Sometimes this may be due to problems with your Internet service provider, and you need to wait a few minutes, or contact the provider's support team. However, if access to the Internet does not resume, then you need to check whether all necessary protocols are enabled in the connection properties. Open a window, this can be achieved in several ways:

Method 1: Right click on the icon "Net", which is located in the notification area on "Taskbars", and select the section from the pop-up menu.

Or press the keyboard shortcut together "Windows + X" and select section.

In the window that opens, in the right pane, move the slider down and click the link.

Method 2: The simplest and most quick way, press the keyboard shortcut together "Windows + R", in the window "Run" enter in the command line field "ncpa.cpl".

A list of connections will open in the window. Right-click on the connection you use to access the Internet and select "Properties".

Pay attention to the section "The marked components are used by this connection". The connection protocol cell should be checked in it "IP version 4 (TCP/IPv4)". IN otherwise you need to enable it by checking the box in the cell. If your protocols are enabled, but Internet access does not appear, then try setting up this protocol manually. Click the button "Properties" and go to the next settings window.

Check the box "Use the following IP address" and fill in the fields "IP addresses" And "DNS servers". You can find out the input parameters by contacting your Internet service provider's support team. Click the button "OK" to save your changes.

The problem with Internet access should now disappear.

METHOD 4: Using Registry Settings

This method is suitable for "Windows 7, 8, 8.1" and only if none of the connection types are displayed in the folder. Remember that the procedure for editing the registry requires you to be careful and accurate. Otherwise, you may make erroneous changes and disrupt the correct operation of the operating system as a whole or its individual applications. Be sure to save its original settings before editing the registry. In the main menu ribbon, click on the tab "File" and select the section in the menu that opens "Export". Name the registry file, select the path to store it and click the button "Save". Now you can always use the saved version of the registry if the need arises.

METHOD 5: Manually reset TCP/IP settings

If you are not using an operating system "Windows 10" then you can manually reset the network adapters and network settings using some built-in commands in the command line and that should fix the problem.

In this article we tried to describe some of the problems that arise when accessing the Internet and ways to overcome them. But this list is far from complete and it will be further supplemented with new methods for correcting errors and problems when connecting to the Internet.

If your desktop computer or the laptop is connected to the Internet, then an unpleasant moment may come when you lose access to the network, and the network connections icon in the notification area will be crossed out with a red cross. When you hover your cursor over it, a message will appear explaining everything. "No connections available". This happens especially often when using a Wi-Fi adapter. Let's find out how to solve a similar problem if you are using a PC with Windows 7.

There are quite a few reasons that can cause the problem we are studying:

• Real absence available networks;
• Damage to the Wi-Fi adapter, router or modem;
• PC hardware failure (for example, network card failure);
• Software glitch;
• Lack of current drivers;
• Damage to the operating system;
• Virus.

We will not talk in detail about such a banal reason as the real lack of accessible networks. This can only be “cured” by returning to the Internet accessibility zone or changing the connection method to one that is valid in the given area. There is also no point in talking too much about hardware faults. They can be eliminated either by a hardware repairman or by replacing a failed part or equipment (Wi-Fi adapter, network card, router, modem, etc.). But we’ll talk in detail about the other reasons and ways to eliminate them.

Method 1: Standard diagnostics

First of all, if you experience the error discussed in this article, follow these simple steps:

• Unplug the Wi-Fi adapter from the computer connector and then connect it again;
• Reboot the router (it is better to do this by completely disconnecting it from the power supply, that is, you need to remove the plug from the socket);
• Make sure you have your Wi-Fi hardware switch turned on if you are using a laptop. It turns on different models laptops in various ways: either using a special switch on the case, or using a specific key combination (for example, Fn+F2).

If none of the above helped, then it makes sense to make standard procedure diagnostics

Unfortunately, this method helps in a fairly limited number of cases. Therefore, if you are unable to resolve the problem when using it, then proceed to the following methods, which are described below.

Method 2: Enable Network Connection

It is likely that the cause of the error may be a disconnected connection in the network connections section "Control Panels". Then you need to activate the corresponding object.

1. Click "Start" and open "Control Panel".



2. Go to section "Network and Internet".



3. Go to "Network Control Center...".



4. In the left part of the window that appears, click on the inscription "Changing adapter settings".



5. The window that appears shows all configured for this computer network connections. Find an item that is relevant to you and look at its status. If set to "Disabled", then you need to activate the connection. Right-click on the object ( RMB) and select "Turn on".



6. After activating the connection, the problem described in this article will most likely be resolved.

Method 3: Removing the adapter from Device Manager

If you connect to the Internet via a Wi-Fi adapter, then one of the ways to solve the problem is to disable it in "Device Manager", and then reactivation.

1. Go to "Control Panel" by the method that was considered in the description Method 2, and then open the section "System and Security".



2. Click on the one posted in the group "System" element "Device Manager".



3. Will start "Device Manager". In the list of equipment types that opens, click on "Network adapters".



4. In the drop-down list, find the name of the equipment that you use to connect to the Internet. Click on it RMB. Carefully examine the context menu that appears. If it contains a clause "Engage", click on it. This will be enough and all further actions described in this method, you won't need to perform. The device was simply turned off, and now you have turned it on.

   

   If there is no specified item, then this means the probability malfunction devices. Therefore, it needs to be temporarily deactivated and then turned on. Click on context menu "Delete".



5. A dialog box will open warning you that the device will now be removed from the system. Confirm your actions by clicking "OK".



6. The procedure for deleting the selected device will be performed.



7. After that in horizontal menu click "Action", and then from the list that opens, click "Update configuration...".



8. A search will be made for devices connected using the technology "Plug and Play". The network adapter will be reconnected, and its drivers will be reinstalled.



9. Next, restart your PC. Perhaps after this the connection availability error will disappear.

Method 4: Reinstalling drivers

One of the reasons for the error we are studying is that incorrect or outdated network adapter drivers are installed in the system. Most often it occurs when connecting the device for the first time or after reinstalling the OS. Then the drivers should be replaced with a current analogue. It is advisable to use exactly those copies that were supplied on a CD or other media along with the device itself. If you do not have such media, you can download the required object from the official website of the adapter manufacturer. Using similar software from other sources does not guarantee a solution to the problem.

1. Go to "Device Manager", using the same algorithm of actions as in the previous method. Open the section again "Network adapters" and click RMB by the name of the desired device. In the list that appears, select "Update drivers...".



2. Next, the shell for selecting the update method is activated. Select an option “Search for drivers...”.



3. In the window that opens, you must specify the media and directory where the drivers will be installed. To do this, click "Review…".



4. The shell opens "Browse folders". Here you need to indicate the folder or media (for example, CD/DVD) where the drivers supplied with the device or pre-downloaded from the official website are located. After selecting a directory, click "OK".



5. After the directory address is displayed in the driver search window, you can proceed to install them by clicking the button "Next", but before doing this, make sure that opposite the parameter "Including subfolders" the checkbox has been checked.



6. The necessary drivers will be installed, and the problem with the lack of Internet connection will probably disappear.

But what to do if for some reason you do not have the driver media that came with the device, and the company’s official website does not work? In this case there is additional features install necessary drivers, although they are recommended to be used only in the most extreme cases, since they do not 100% guarantee interoperability between the OS and the adapter. You can use the following options:

If your Internet does not start at all, then you will have to search and download from another device.

Method 5: Enable the service

If you use Wi-Fi to connect to the Internet, the problem we are investigating may occur due to a service outage "WLAN Auto Configuration". Then it needs to be activated.

1. Go to the section "Control Panels" called "System and Security". This is discussed in the description Method 3. Click on the title "Administration".



2. In the list of system tools that opens, select "Services".

   

   "Service Manager" can be activated in another way. To do this, dial Win+R and enter in the displayed area:

   Then apply button click "OK".



3. "Service Manager" will be open. To quickly find an element "WLAN AutoConfig Service", arrange all services in alphabetical order by clicking on the column title "Name".



4. Find the name of the desired service. If the status is not set opposite its name "Works", then in this case it is necessary to activate. Double-click on her name with the left mouse button.



5. The service properties window opens. If in the field "Startup type" set value "Disabled", then in this case click on it.



6. A drop-down list will open where you need to select "Automatically". Then click "Apply" And "OK".



7. After returning to the main interface "Service Manager" select the name "WLAN AutoConfig Service", and on the left side of the shell click "Run".



8. The service will be activated.



9. After this, the status will be displayed opposite its name "Works" and the problem with lack of connections will be solved.

Method 6: Checking system files

If none of the above methods help, then there is a possibility that the integrity of the system files has been compromised. In this case, it is necessary to perform an appropriate check and then restore if problems are found.

1. Click "Start" and select "All programs".



2. Open the folder "Standard".



3. Find the element with the name "Command line". Click on it RMB. From the list of action options that appears, choose to run as administrator.



4. Opens "Command line". Type into its interface:

   Then click Enter.



5. The procedure for scanning the integrity of system elements will be launched. Information about the dynamics of its passage will be displayed right there in the window. "Command line" in percentage terms. While this process is running, you should not close the current window, but you can minimize it. If violations in the structure are detected, a procedure for restoring missing or damaged files will be automatically performed.



6. If, after completing the scanning procedure, a message appears informing you that recovery is impossible, repeat the entire process again, but this time you will need to start the OS in "Safe Mode" .

Method 7: Eliminate viruses

The cause of the problem of lack of available networks may be a virus infection of the computer. Some malware Internet access is specially disabled so that the user cannot use external assistance to remove them, while others simply arbitrarily “kill” or modify system files, which ultimately leads to the same result.

To remove malicious code, there is no point in using a standard antivirus, since it has already missed the threat, which means it will not react to the virus, and may also be infected by this time. Therefore, we recommend using specialized anti-virus utilities that do not require installation. One of best programs This class is Dr.Web CureIt. It is best to check from another device or when starting from LiveCD/USB. This is the only way to ensure the maximum likelihood of detecting a threat.

If antivirus utility will discover malicious code, then in this case follow the tips that will be displayed in its interface. There is a possibility that the virus has already damaged system files. Then, after eliminating it, it is necessary to carry out the appropriate check discussed in the description Method 6.

As you can see, the source of the problem with the availability of connections, and therefore with the performance of the Internet, can be a lot of different factors. They can be both external (real lack of network) and internal (various failures), caused by both the software and hardware components of the system. Of course, before fixing a problem, it is recommended to establish its exact root cause, but, unfortunately, this is not always possible. In this case, simply use the methods described in this article, checking each time whether the malfunction has been eliminated or not.

It happens that the Internet on the computer does not work due to a banal loose connection of contacts or mixed up wires, so first of all you need to make sure that the internet cable is connected.

• Cable check

In the case where the power cord goes directly to the PC, make sure that on the back of the PC or laptop it fits tightly into the Ethernet port. If the connection is made through a router, check the following inputs: on the PC - Ethernet, on the modem - LAN (the cable must come from the computer) and WAN (actually, the network line itself).

But sometimes the reason that the Internet does not work on a computer via a cable is the cable itself, the router or the PC. First you need to find out the source of the problem. Connect the cable to another PC or laptop. No internet connection? This means that the cause of the problem is in the line.

• Cable problems

When in operating mode, the indicator on the router will light up. Lack of connection is reflected on the monitor with the “Connection Problems” icon.

What is the essence of the problem? Most likely the root of the problem is:

• wire damage;
• RJ-45 connector failure;
• incorrect connection of wires (see paragraph Checking the cable).

If everything works stably, the lack of a signal may be due to repair work or untimely replenishment of the account. You can find out why the Internet is not working on your computer from your provider.

• Problems with the router

If, after checking several devices via the modem, none of them were able to connect to the network, most likely the router is not working properly (if there is no problem with the cable).

• wiring errors;
• damage to the nest;
• device freezing;
• incorrect setting;
• DHCP server is disabled.

What to do if the Internet does not work on your computer? Try to swap cables, select another LAN connector (usually there are 4), reboot (turn off/on) the modem.

• Computer problems

You can often see a triangle or circular arrows (identification) next to the Internet connection icon. If there are no problems with the cable and router, you should check your computer.

Among the common reasons:

• broken/incorrect network card configuration;
• damaged Ethernet socket;
• the need to reinstall the driver;
• lack of IP connection;
• signal blocking by viruses.

One last thing: sometimes just rebooting your laptop is enough.

Problems connecting to the Internet via Wi-Fi

In general, problems with Wi-Fi connections are almost the same as the previous ones. This could be cable damage, the router freezing, or the need to install a driver on the PC. But you also need to take into account a number of nuances related to the nature of the connection itself. For example, signal stability and range. Perhaps you are simply out of Wi-Fi range.

If, when connecting through a router, the Internet does not work on your computer or other devices, the difficulties probably lie in incorrectly configured parameters of your router. Look at the system notifications on the monitor of your computer or laptop: icons on the taskbar, which may be as follows:

• "No network access."

First of all, check if the adapter is working and if the Wi-Fi drivers are installed. The problem may be due to the Wi-Fi function being disabled on the laptop.

• Message "Windows could not connect to..."

Usually the problem is related to blocked access. You are required to enter your Wi-Fi password. Even if you have used the Internet from this PC before, re-enter the data and try again, the connection should work. If unsuccessful, the reason should be sought in the router or IP address assignment.

Frequently Asked Questions

Why does it show a Wi-Fi password error?

You may have changed your keyboard layout or pressed CapsLock. If you have forgotten your password, you can look it up in the router settings. We recommend setting a simple, easy-to-remember password.

Connect to the Internet Wifire: stable connection without interruptions.

Tariffs and services of Net By Net Holding LLC may be changed by the operator. Full up-to-date information about tariffs and services is in the “tariffs” section or by calling the phone number listed on the website.

By default, when using a Wi-Fi connection from a laptop or computer, the Internet and network should connect automatically. The user does not have to think about what and where to turn on, as when working with wired Internet.

Here is one of the main advantages of this connection- this is the ability to turn on from the first second, without waiting.

But it also happens that it was not possible to automatically connect to the proxy server. What does it look like and what should a simple newcomer to the Internet community do in this case? The reason for this problem is hidden in the settings for connecting to the proxy server. You could change them:

• accidentally - by a key combination, or in case of a sudden power outage (in the absence of an uninterruptible power supply), etc.;
• because of a virus - very often settings are lost due to malware not being completely removed( software).

What do connection errors with a proxy server look like?

The complexity of such problems is that when the Internet is connected, it will look like it is turned on in the command line, and even torrents will work and Skype can work, but it will become impossible to start working in any window. It will open, but will not load. Everywhere it will be written that there is no connection to the proxy server.

The signature can be in English or Russian. Only one tab may not open or different browsers. Or maybe this error occurs in all browsers.

There is no connection to the proxy server, which just means that somewhere the automatic connection to the network is broken, which does not require human intervention.

No connection to the server

An important note - Problems with automatic connection have nothing to do with the operating system (OS). Therefore, there can be no problems here. The difference will be small only in correcting such a problem on different operating systems -7, or 8, or 10.

IN in this case, the main thing is not to be hysterical, not to say that repairs will cost a lot of money. And there is no need, in a fit of imbalance and with a hot head, to start with:

1. Reinstalling browser(s);
2. Reinstallation of the entire OS.

Fixing a connection error using the example of the Chrome browser

To fix connection errors with a proxy server in any browser, the first thing the user should find is simple Settings.

After pressing the button, a window with settings opens. But not all of them may be displayed. Therefore, the user needs to look at the window, and if there is nothing with the proxy server signature, click the Change proxy server settings button. Then the user will see on the screen window in which you should already select change Internet settings.

It will automatically open on the connection option (if not, you need to select it) and then press the button - Network settings.

After that, the user in a new window must check the option automatic detection parameters and click ok to fix the connection.

And then the apply button is pressed and you can check the error correction. Mozilla works according to a similar scheme. But the end of the procedure is slightly different. Through Settings, find Advanced, then Networks, and then select Configure. Be sure to select the option WITHOUT PROXIES. It will be better this way.

Fixes via Internet Options

After the user has corrected the network disconnection settings in all browsers, the connection needs to be updated via Windows. To do this, the following sequence of actions is performed:

1. Through Start and Control Panel, browser properties are selected.
2. In the new window that appears, select again automatic connection to the proxy (the window will be one to one, as when correcting it in Google Chrome). And changes are accepted.

Checking your Internet connection

And now you can try to adjust the automatic connection to networks using the tools available in the OS. To do this, select Start, then Control Panel and Network Control Center.

Network Management Center

Then you need to select - change adapter settings. Then there you will need to move the mouse to the “local network connection” shortcut and select properties after right-clicking.

In the connection to the local network, in the Networks tab, you need to check the box or highlight the line Internet Protocol Version 4 (TCP/IPv4). And as always, click OK.

Then you need to make this line with the connection active, stand on it, and click the Properties button, which is just below. A new window will appear. It must automatically select both IP and DNS addresses.

Just in case, you can also run via command line the following phrase is ipconfig /flushdns. But this requires administrator rights.

Fixing virus automatic connection errors

Things will get worse if automatic settings crashed due to a failure, a power outage, or a virus that was not completely removed. Then the computer will have to be “treated”. Settings can be lost due to a virus in two cases:

1. After checking with antivirus;
2. Due to a contracted virus.

You can fix such errors with the same antivirus. But the program should be simpler so that it does not interfere with the settings, for example, this AVZ.

In this program, you should select restore system settings through “File” and check all the boxes, exactly as in the figure below. Then click Perform the marked operations.

After this, you can reload the browser and try to see if Internet pages open.

As for directly antivirus programs, then in this case it is better to use one-time checkers, without permanent installation on the computer. These could be:

• Kaspersky repair tool;
• Dr.web

Cleaning the registry - as an option to fix auto-connection to the network

Another option to fix automatic connection is clean registries.

In the operating line of the OS window, type HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\WindowsNT\CurrentVersion\Windows\

In the window that opens, you need to check the Appinit_DLLs folder or file. There shouldn't be anything in it!

In OS version 10, this file will be named AutoAdminLogan.

All possible options fixes for connecting to the proxy server have been sorted out. If all else fails, then you should call a specialist. This means that something more serious happened to the computer than lost settings.

Error message connection failed - what to do?

Another problem with connecting to networks and working in social networks. Very often, when loading sites on the Internet, an annoying window with the following content appears:

Connection failed error

This same error can very often be referred to on the network as connectionfailure error. Such inaccuracies should be kept in mind when searching. This is just that magical option when you can log in to some sites, but on others you get this error. There is most likely no reason for this to be a virus. In most cases, this problem is caused by:

1. Blocking firewall (denies access to a site or sites);
2. Communication problem (no connection to the site yet);
3. The antivirus automatically blocked this site;
4. The settings of your Internet service provider have changed.

To solve the firewall problem, you will have to turn the firewall on and off. If sites are blocked due to the antivirus being turned on, you will have to disable such blocking on the antivirus. This is what it might look like on Avasta. All you need to do is update your antivirus to remove blocking links.

Updating signatures

And if there is no truth in any of the proposed options, then all that remains is to call the provider and find out if preventive work is being carried out somewhere. Yes, and there is such an option that the wires were cut in the yard or the user did not pay for the services.

Setting up network access and disabling it on Windows 7,8, 10

Connecting to a computer or laptop network can be done in two ways:

• via a wired network;
• through wireless network using Wi-Fi.

But besides these nuances, there is also the type of operating system that needs to be taken into account. And if the seven and eight with modifications are similar to each other, then the ten may have its own difficulties.

How to connect an Internet connection via a wired cable and via a wireless network for Windows 7 is officially published in great detail and easily accessible on the Windows website. Version 8 needs to be connected to the Internet in much the same way.

Thus, the user will not be confused or lost if suddenly the computer starts swearing about inaccessible pages. It will be enough to first try all the above methods on your own, and only then go to the workshop.

Today for many it is already an urgent need. Modern equipment and operating systems 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 a yellow triangle with an exclamation mark.

Microsoft operating systems, starting with Windows 7, constantly monitor network connections, and since global network is unavailable, they report it immediately. There are many reasons why your computer may not have an Internet connection. These 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 transmission lines are damaged, some technical work or you simply forgot to top up your account on time.

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

Physical connection problem

Cases are not so rare when a partially broken network cable or a loose connection in the connector. And if you have pets or children, then the likelihood of such a development of events increases. Even Wi-Fi users should not forget that 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.

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 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). 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 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), 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 will have to be configured again!

Cleaning DNS cache using the command line

You have a direct connection to your provider

The option when your computer is connected directly to the provider, bypassing the router, is now becoming less and less common, since the number network devices is growing steadily. But what to do if you have just such a connection? Eliminate possible problems with drivers as described above, and check that the connection settings are correct. Regarding the settings, the best option 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 editor group policies. In the menu on the left, go through the items: Policy " Local Computer» - Computer Configuration - Administrative Templates - System - Internet Communication Management - Internet Communication Settings. Now, on the right side of the window, find and enable “Disable active probing for network connection status indicator.” In Windows 10, this setting is called "Turn off active network connection health checks." Please note that now, even if there is truly no connection, the message will not appear.
