The network is there but without access to the Internet. The Internet does not work via a network cable from the router. Unidentified network when connected via Wi-Fi

At least once in his life, every computer or laptop user has faced the problem of connecting and configuring the Internet on his device. One of these cases is when, when you connect an Ethernet cable (network cable) to a PC or connect to a WiFi network, instead of accessing the computer to the Internet, you receive the inscription "Unidentified network", and appears on the network connection icon located in the panel near the clock yellow triangle with exclamation mark.

This can happen both when you first connect to the network, and after restarting a laptop or PC, and even on computers with just installed system Windows.

The reasons for the appearance of the problem are different and further we will consider ways to solve them.

Invalid network card settings - IP address problem

Occurs if the network card has been manually assigned an IP address and when connected to new network she cannot get another. To check this, follow these steps:

Step 1 Open the START menu and select Control Panel

Step 2 Find a program Network Control Center and general access and run it

Step 3 In the window that opens, in the left pane, select Change adapter settings

Step 4 Now select network connection through which you are trying to access the Internet, click on it with the right mouse button and in context menu select Properties

Step 5 In the connection properties window, select Internet Protocol Version 4 (TCP / IPv4) and click on the Properties button, which is located just below

Step 6 Check the specified parameters in the window that opens:

• if you are connecting to a WiFi network or using an Ethernet cable from a router, then check the boxes for automatic receipt so that the computer can get a new address

• if you connected the Internet cable directly to the computer, bypassing WiFi router, and your provider provides access to the Internet with a binding by IP address - check the specified parameters (IP address, gateway and DNS server addresses), you can see them in the agreement or contact the technical support of the provider

Problems with TCP / IP

Occurs when internal TCP / IP errors occur, which requires a protocol reset.

Step 1 Run the program Command line (cmd.exe) as administrator

Step 2 Enter the command: netsh int ip reset resetlog.txt and press Enter

Step 3 Restart your computer

Network card driver

Occurs when after Windows installations the drivers for the network card are automatically installed by the OS itself or you are using the Driver Pack. Often this problem appears on laptops and to fix it, you need to install drivers from the official website of the laptop manufacturer or the computer's network card.

DHCP issues

Most often occurs when you connect an Internet cable or cable for the first time local network to a laptop or computer. To check this, open a command prompt and enter the command: ipconfig

If in the line IP-address or default gateway you see an address with the following content: 169.254.x.x- it means that the system could not get an IP address automatically and the problem lies precisely in DHCP.

In this case, follow these steps:

Step 1 Open Dispatcher Windows devices ... To do this, press the Win + R key combination on the keyboard and in the window that appears, enter the command: devmgmt.msc

Step 2 Find the network adapter through which you are trying to connect to the Internet, click on it right click mouse and select Properties

Step 3 In the window that opens, go to the Advanced tab

Step 4 Select an option Network address(Network Address) and in the field Meaning write in 12 characters (use numbers from 0 to 9 and letters from A to F), then press the OK button

Step 5 Go back to the program Command line and enter the following values:

ipconfig / release
ipconfig / renew

Step 6 Restart your computer and check if the error is resolved. Launch type from the drop-down menu select Disabled, and in the section State click the Stop button

Step 5 Now click OK and restart your computer

We hope that at least one of the presented tips will help you fix the problem with an unrecognized network on your computer or laptop.

The Internet is an integral part of our life - it is an excellent assistant in work, an indispensable tool in learning, moreover, it is a means of communication and recreation. Connectivity issues are common among users. Let's look at the most common error in this article - IPv4 without Internet access and how to fix it? If Windows has given you this alert, then you should use the method of exclusion to enumerate all the options in order to find out what caused the occurrence.

Ipv4 is the Internet Protocol, I think it does not need translation, and the protocol version is the fourth. You probably noticed the presence of the IPv6 protocol in the settings - this is also the Internet protocol, but already the sixth version, only a few providers use it. The most widespread and mainstream today is IPv4. The main task of the IPv4 protocol is to ensure the functioning of the computer and networks according to the established rules for the exchange of data packets. So, the interaction takes place between the communication node and the IP address of the machine, IPv4 is a low-level protocol.

If the terminology causes you difficulties, then we additionally recommend that you familiarize yourself with our other article,

In order to correct the access problem accurately and as quickly as possible, we will consider the cause and the method of its elimination.

Reboot: reboot will fix the error

It is not for nothing that the well-known proverb in the circles of IT specialists has taken a new form and sounds like: "Seven troubles - one reset". In our case, reset is a last resort to fix the error. Terms:

• reset - or rollback to the last successful version;
• reboot - reboot, in other words, complete unloading and loading of the operating system;
• restart - restart.

Let's start correcting the situation.

1. Restart your computer (do not turn off and on!). This is sometimes a very effective method to fix the problem.
2. 99% of users use routers and routers, since there is more than one device with Internet access in the house - restart the router / router.
3. Try to suspend or completely disable the antivirus, for various reasons, blocking occurs because of it. If everything works, reinstall the antivirus and you may need to update the program module.
4. Analyze what changes were made to the system before the IPv4 error occurred without network access. Try to roll back the installation / configuration of the program / utility, etc., if this corrected the situation, then the reason is precisely in the changes made earlier.

Small experiments ...

Did the above steps fail to fix it? Going further, it is necessary to exclude the possibility of a problem on the side of the provider, namely, to check whether the Internet works on other devices.

1. Check the other device for network access. If everything is working on that device, and there is no IPv4 error without network access, then the problem is with the computer. This can be either a software error or a physical malfunction. We will consider the software error in more detail below, and the physical error can be from a detached network cable (patchcourt) to a breakdown of the network card.
2. If the machine is directly connected without the participation of a router, and an IPv4 error occurs without access to the network, try connecting another computer / laptop instead. Again, depending on whether it works or not, we check the physical condition and then move on to software solutions.
3. If the network does not work on any of the devices connected by any of the methods, call technical support your ISP for explanations and do not forget to voice that Windows displays the message "IPv4 without Internet access". They should help fix it.
4. Probably, this will sound trite and even a little funny, but if our smaller brothers live at home, check the integrity of the cables, damage is possible, which was the above error - IPv4 without access to the network.

Behold at the root ...

After eliminating a number of simple reasons, in order to fix the problem, let's move on to the most important ones. The world wide web does not work, but operating system gives an error: IPv4 without Internet access. So let's start in order.

Internet settings: provider and router

Of course, the simplest thing is to call the provider and clarify everything with him, having previously said about the error - IPv4 without access to the Internet. Perhaps a specialist will advise how to fix it. First, you need to look into the settings of your router and check whether the data has been entered correctly. Let's see what the IPv4 error without internet access looks like. Regardless of the connection made via Wi-Fi or using a network cable - a yellow exclamation mark will appear.


I would like to make a reservation that the fix for the problem with the IPv4 name without network access is the same for different connections, and Windows versions from 7 to 10. To fix, you must first find out the cause of the IPv4 error without Internet access.
Go to the "Network and Sharing Center" - using any of the 2 methods:

1 way

 right-click (hereinafter RMB) click on the connection sign with a yellow exclamation mark → select "Network and Sharing Center" → note that the "Access type" says "No Internet access" → select "Change adapter settings" → find your connection;

2 way

Once you get to the right directory:

• will launch "Diagnostics Windows networks"- wait for the completion and as a result - the detection of problems, as well as advice on how to fix them.
  
  
• diagnostics determined that this is main reason IPv4 errors without Internet access;
  
  
• to fix it, go to the window "Status - Ethernet" or "Status - Wireless network connection" - in the above way;
• select "Properties" → select "Internet Protocol Version 4 (TCP / IPv4)" → "Properties".
  
  
  In the window that opens, you must specify the type of IP address and DNS. Let's describe all the possible options for how to fix the IPv4 problem without Internet access.
  
  

Static IP and DNS

Is it configured home network in such a way that each device has its own and access is carried out with the indication of DNS? To accurately specify the settings and fix the IPv4 error without access to the Internet, go to your router, we show it using the Asus router as an example.

• the address of the settings page is available at the address "192.168.1.1" - we enter without quotes in the address bar of the browser → → authentication is required, as a rule the login and password are "Admin", you can also log in without specifying a password;
  
  
• go to the section "LAN" → "IP - LAN address" → the specified IP - address is the main gateway;
  
  
• then go to the section "DHCP - server" - here you can see the initial and final pool of addresses, as well as a list of those already assigned by the MAC - address of the device. MAC - address is unique serial number network card. Find desired device and remember / write it down.
  Dynamic IP address

  It so happens that everything is configured correctly, but a DNS server error occurs and the system issues a message - IPv4 without access to the network. This is due to an overload or an error in the operation of the DNS servers on the provider's side. Moreover, in the router you can see that the Internet reaches you. In this case, alternative DNS from Google that are public. So:

  
  

  With such a simple method, you can fix the arising IPv4 connection error.

  Stable connection!

One of the most common problems that users encounter when connecting to the World Wide Web is a failure, characterized by two notifications: the lack of access to the Internet and the presence of an unidentified network. The first of them is displayed when you hover the cursor over the network icon in the tray, and the second when you go to "Control center"... Let's find out how to fix the indicated problem while working with Windows 7.

There are several possible reasons occurrence of the above situation:

• Operator side malfunctions;
• Incorrect router configuration;
• Hardware breakdowns;
• Problems inside the OS.

In case of problems on the side of the operator, as a rule, you just need to wait until he restores the network's operability, or even better, call and clarify the cause of the malfunction and the timing of its elimination.

If the hardware parts fail: a router, a modem, a cable, a network card, a Wi-Fi adapter, you need to return the faulty components for repair or simply replace them.

Separate articles are devoted to the problems of configuring routers.

In this article, we will focus on eliminating the error "Unidentified network", which arose due to incorrect settings or failures inside the Windows 7 OS.

Method 1: adapter settings

One of the reasons the specified error are incorrectly entered parameters inside adapter settings.

1. Click "Start" and go to "Control Panel".



2. Open up "Network and Internet".



3. Move to "Control center…".



4. In the opened shell in the left area, click "Change settings…".



5. A window with a list of connections is activated. Please select active connection that works with the above error, right click on it ( PKM) and in the list that appears, select "Properties".



6. In the window that opens, in the block with the list of elements, select the Internet protocol of the fourth version and click on the button "Properties".



7. The window of protocol parameters will open. Move both radio buttons to position "Receive…" and press "OK"... This will allow automatic assignment of the IP address and DNS server address.

   

   Unfortunately, even now, not all providers support automatic settings... Therefore, if the above option did not work, you need to contact your ISP and find out the current IP and DNS address settings. After that, set both radio buttons to the position "Use…" and fill in the fields that have become active with the data provided by the Internet operator. Having done this, press "OK".



8. After performing one of the two options indicated in the previous step, you will return to the main window of the connection properties. Here, be sure to click on the button "OK", otherwise the previously introduced changes will not take effect.



9. After that, the connection will be identified and thus the problem with the unrecognized network will be resolved.

Method 2: Installing Drivers

The problem analyzed in this article may also be caused by incorrect installation of drivers or installation of drivers not from the manufacturer of the network card or adapter. In this case, you need to reinstall them, without fail using only those that are officially provided by the device developer. Next, we will consider several options for action to achieve this goal. Let's start with a simple reinstallation.

1. Go to "Control Panel" using the same steps as in the previous method. Go to the section "System and safety".



2. Click on the name of the tool "Device Manager" in the block "System".



3. The interface will open "Device Manager"... Click on the block name "Network adapters".



4. A list of network adapters connected to this PC will open. Find in it the name of the adapter or network card through which you are trying to access the world wide web. Click on this item PKM and in the drop-down list select "Delete".



5. After that, a window will open where you need to click "OK" to confirm the action.



6. A procedure will start during which the device will be removed.



7. Now you need to reconnect it, thereby reinstalling the driver, which is required. To do this, press "Action" and select "Update configuration ...".



8. The hardware configuration will be updated, the network card or adapter will be reconnected, the driver will be reinstalled, which in the end is likely to help fix the problem with the unrecognized network.

There are times when there are problems with the drivers, when the above algorithm of actions does not help. Then you need to remove the current drivers and install an analog from the manufacturer of the network card. But before uninstalling, be sure to make sure you have the correct drivers. They should be stored on installation disk that came with the network card or adapter. If you do not have such a disk, the necessary software can be downloaded from the manufacturer's official website.

Attention! If you are going to download drivers from the manufacturer's official website, you need to do this before starting the procedure for removing the current ones. This is due to the fact that after uninstalling you will not be able to access the World Wide Web, and therefore download the necessary objects.

There are several options for actions in case of an error with an unrecognized network in Windows 7 when trying to connect to the Internet. The solution to a problem depends on its specific root cause. If the problem was caused by some kind of malfunction or incorrect system settings, then in most cases it is solved either by configuring the adapter through the OS interface, or by reinstalling the drivers.

In this article, we will deal with probably the most popular problem that occurs on computers with Windows 7, when connecting to the Internet via Wi-Fi. it "Without internet access", when, after connecting to a Wi-Fi network, the Internet does not work, and a yellow triangle with an exclamation mark appears next to the connection icon on the notification panel. And if you move the cursor over this icon, the inscription "Without Internet access" will appear.

And in the network control center, there may still be an inscription "Unidentified network". I myself have encountered this problem more than once, the solutions are very different. Now we will try to figure out what to do if your connection has become without access to the Internet. On this page we will solve the problem For example Windows systems 7 , since in Windows 8, 8.1 and 10, there are a number of other reasons and solutions, therefore, there will be a separate article on them. Since this error may appear when connecting to the Internet via network cable, or via Wi-Fi, then in this article we will deal with wireless Wi-Fi network connection... And with the problems of accessing the Internet via cable, I will also write in a separate article, so that the instructions are simpler and more understandable, and you do not get confused.

This means that if you have a laptop on Windows 7, you are connected to your Wi-Fi router, and you have a connection without access to the Internet, then you went to the address, now we will try to solve the problem that has arisen.

Windows 7: "No Internet Access". What to do and how to find the cause?

I looked at articles on solving this problem on other sites, and almost everyone immediately writes about some actions that need to be performed on laptops. Check IP settings, etc. But, as practice shows, the reason why the Internet does not work in Windows 7 when connected via Wi-Fi is the router itself, its settings, or the Internet provider.

The main thing is to determine what the problem is, in a laptop, a router, or an Internet provider. Then you can already do something to solve the problem.

Now I will explain everything, and I will tell you, what to do first:

• Many have such the problem appears in the process of configuring the router... If you are setting up your router, it seems that you have already configured it, connected a laptop to it, and the connection status is "Without access to the Internet", sites do not open, then you need to look for the problem in the settings of the router. Most likely, you have incorrectly configured the router to work with the provider, take a look. Find instructions on how to configure your route on our website, or write in the comments, I will try to tell you where to look at these settings. Connect other devices to the internet (if possible) check if they work.
• If you have such a problem with Wi-Fi appeared unexpectedly, the Internet worked and suddenly stopped, or after turning off / on, then first of all, restart your computer (laptop) and router... Then, reconnect. Perhaps this will fix the problem.
• Check if Is the cable from the provider to the router connected correctly? whether it is well inserted into the WAN connector. I had a case when the Internet did not work for my relatives - "Without access to the Internet." For a week, everyone sat without the Internet. I looked, and it turned out that they connected the cable from the provider to the wrong connector on the router (connected to LAN, disconnected during a thunderstorm):). I just changed the connector and the internet started working.
• Make sure to you paid for the internet... Perhaps the provider simply cut off the Internet for you for non-payment.
• Determine what the problem is: in a laptop, router, or Internet service provider. This is not difficult to do. For example: try connecting another device to this router. If the Internet works on it, then the problem is in your computer. If the Internet does not work, then the problem is either in the router itself or in the Internet provider. To check who is to blame, the router, or the provider, you need to try to connect the Internet directly to the computer to the network connector. Bypassing the router. If the Internet is working, then the problem is most likely in the router. You can also call the provider and ask if they have any problems in your area. Once again I will write that it is very important to determine what the problem is.
  You can also connect your laptop to the router not via Wi-Fi, but via a network cable. Perhaps this is how the Internet will work.

With the most important points sorted out, you can proceed to solving this error. I think you found the reason.

Solving the error "No Internet access" if the problem is in the laptop

If, for example, the Internet is working on other devices, but not on your computer, then most likely the problem is in it. It would be nice to immediately try to connect it to other networks, see how it will work. If the problem with the Internet via Wi-Fi on Windows 7 appeared suddenly, then try to remember whether you installed something or changed some settings.

The most popular solution in Windows 7, which everyone advises, is to register static IP and DNS, or vice versa, try to set the automatic receipt of these parameters if you have static data. I already wrote about this in the article. Let's try.

Right click on the internet connection icon (which we should have with a yellow badge) and select Network and Sharing Center.

Right click on the adapter Wireless network connection and choose Properties... In the new window, select the line Internet Protocol Version 4 (TCP / IPv4) and press the button Properties... If you have set up automatic obtaining of IP and DNS there, then set the static parameters, as I have in the screenshot below. Your IP and Default gateway may differ. It depends on the IP address of your router. (can be seen on the sticker, on the router itself)... Maybe IP 192.168.0.50 (50 is a number you can set another, for example, 100)... DNS set: 8.8.8.8 and 8.8.4.4 .

If you just opened the parameters, and you already have some settings, static addresses, then set automatic obtaining IP and DNS... You should try with static addresses too (set manually), and with automatic receipt.

Save your settings and restart your laptop. Perhaps changing these settings will solve the problem with Internet access.

Another solution: enable Federal Standard Compliance (FIPS) mode

Click on the internet connection icon in the notification bar, then right-click on your Wi-Fi network to which you are connected (and with which problems are observed), and select Properties... In the new window go to the masonry Security, click on the button Extra options , and check the box next to Enable Federal Information Processing Standard (FIPS) Compliance Mode for this network.

Click on Ok, and restart your laptop.

How can you still try to fix this error in Windows 7? You can also disable antivirus, firewall, and other programs that can block the connection. If all else fails, then you can still update the driver for the Wi-Fi adapter of your laptop, there is a little information about this.

How to fix if the problem is with the router or Internet service provider?

Well, I think everything is clear with the provider. If the Internet does not work when connected directly, then the problem is with the provider. Something with equipment, doing some work, etc. Or you just forgot to pay back the Internet. In such cases, we call support and clarify everything. Personally, I have had such cases more than once. I immediately started checking the settings, but it turned out that this was a problem with the provider.

If the router is guilty of everything (in this case, the Internet will not work on any device, on mobile devices sites just do not open) then you need to check the settings and cable. As I wrote above, check if the internet is connected correctly. It should be something like this:

Check everything well, reboot the router.

If this did not help, and especially if the problem arose during the process of configuring the router, then you need to check the WAN settings. Simply put, Internet settings. Most often, the "Without Internet access" error appears when the router cannot connect to the ISP, therefore, there is actually no Internet access. And he cannot connect to the provider, most likely because the parameters for the connection are incorrectly set in the router settings.

In the settings of the router, on the WAN or Internet tab (it is called differently by different manufacturers), you need to correctly specify the type of connection that your Internet provider uses. And set all the parameters that you may need.

I think you will find instructions for the manufacturer of your router.

That's all, I will update the article and add new solutions here. If you know something new about this problem, maybe you solved it somehow differently, then share interesting information in the comments, I think it will be useful to many.

I hope you managed to remove this error, and the Internet on your laptop worked. Feel free to ask your questions. Describe the problem, attach screenshots, I will try to answer quickly, and help with advice.

⭐️⭐️⭐️⭐️⭐️ Now I will tell you what to do when on Android phone no internet via WiFi. Those. the connection to the network itself is there, the wifi icon is active, but it is impossible to access the Internet and messengers (Telegram, Viber, Skype) and other applications (Instagram, VKontakte, etc.) are not connected.

This article is suitable for all brands that produce phones on Android 10/9/8/7: Samsung, HTC, Lenovo, LG, Sony, ZTE, Huawei, Meizu, Fly, Alcatel, Xiaomi, Nokia and others. We are not responsible for your actions.

Attention! You can ask your question to a specialist at the end of the article.

I will notice! If you are using public WiFi network or private corporate, then there is a high probability that they block some social networks and messengers. This is often practiced and you have to come to terms with the situation.

In most cases, restarting the smartphone or router that distributes the wireless network helps. Another reason could be a software error in the phone and wrong setting router.

No internet due to a failure in Android itself on the phone

Reboot your phone. If a minor system failure was the cause of the problem, restarting the system will fix it.

After restarting when saving the error, you will need to "Forget the network" and then reconnect to it.

Forgetting the network and reconnecting helps eliminate the Wi-Fi mismatch between your phone and router.

If removing the network did not help, check the status of the proxy server on your phone. It should be off:

1. Go to the "Wi-Fi" section of the settings and select a network to connect.
2. Check the item "Advanced" ("Advanced settings").
3. Make sure the Proxy Server field is None.

Increase

Another reason that the phone does not go online may be the wrong date. To check and change it:

1. Open the settings.
2. Select the "Date and Time" section.
3. Set the time and date manually, or check the boxes "Network date and time" and "Network time zone".

Increase

After setting the correct date, connect to Wi-Fi. If the wireless network really works, you can go online.

Checking for Internet access

Before using your smartphone or router, make sure that everything is in order with the Internet. What could be wrong with him:

• You did not pay, so the provider has suspended Internet access. Make sure there is network access through the wire.
• In the settings of the router, there are restrictions on visiting certain sites or a limit on traffic (a common practice for open networks in public places).
• Problems arose on the provider's side.

After eliminating these factors, proceed to diagnostics to understand which device is hiding the cause of the problem.

The easiest way is to connect to wireless network from another phone / tablet / laptop. If another device goes online, then the problem is in the phone, which cannot establish a correct connection.

Checking and configuring the router

If, as a result of a kind of diagnostics, you found out what occurs on all devices that connect to the same wireless network, then look for the cause of the error in the router settings.

Restart your router first. Unplug it from the mains for 10-20 seconds, then turn it on. Make sure the device is close enough to the wireless network source that nothing is interfering with the signal.

Take a look at the settings and try changing them a little:

When connecting to an open public network, check if you have passed the web login. Usually, when trying to connect to Wi-Fi in a shopping center, a browser is launched with a page for entering a phone number. If you don't, you will be connected to Wi-Fi without internet access.
