Public network without Internet access. Unidentified network without access to the Internet - What to do? For what reasons an error appears

With a sudden Internet shutdown, we usually begins to climb the Windows operating system settings to at least somehow try to return access to the precious information flow. In the end, we fall with you in setting up your Internet connection and see the message "IPv4 without access to the Internet or network".

Obviously, this information is somehow relates to the disappearance of the Internet, right? All so, and in this article we will tell you how to correct the problem in the form of "IPv4 without access to the Internet". It can be solved with a huge number of all sorts of ways and we will consider them all.

However, for a start, we need to specify the possible causes of the loss of the Internet and the appearance of this alarm.

  • Incorrect Internet connection settings that could be exhibited by the user or due to some changes in the system.
  • The problems arising on the side of the user provider.
  • Various errors and malfunctions in the Windows operating system, due to which network access can be blocked or reset the connection settings.
  • Failures in the router (router).
  • The impact of some viruses or malicious software (very rare cases).

Before we proceed to the consideration of the methods that can be used in this situation, you need to specify something else. Next to the message "IPv4 without network access" you can see a line that will report that IPv6 is also without access to the Internet.

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

Errors and malfunctions in Windows are far from a novelty for all users of this ambiguous operating system. It is possible that just one of such mistakes in some strange way could block you access to the Internet. To check this probability, it is fairly simply to reboot its system.

If, after rebooting the system, you have access to the Internet, and the "IPv4 IPv4" string has changed, it was just a one-time failure in the system. If the situation did not change, then let's move on.

Method number 2 restarting router

The router is not the most reliable networking equipment and sometimes it can easily begin to climb, block the output to the Internet, cut the speed of the network connection and create other problems. If you suddenly disappeared the Internet and you found "IPv4 without access to the Internet", then try reset your router.

Run the router is quite simple: disconnect the power from it, wait the seconds of thirty, and then connect it back to the power. Wait until your system detects a network connection, and then check the problem.

Method number 3 Check connection settings

If you recently changed something in the settings of your Internet connection, it was this that could entail it disabling and the "IPv4 without access to the Internet". The problem could arise due to some changes in the settings. For example, did you try to set some static addresses for IP or DNS?

Go to the settings of your connection and put everything for previous values \u200b\u200bif they have been previously changed. If you have not changed anything, you still go to the network connection settings ( Win + R → NCPA.CPL → Properties → Information) And make sure that everything is exhibited correctly.

Method number 4 Turning off the router

If the router reset could not correct the situation with the state of "IPv4 without Internet access" and with the settings of your connection everything is fine, then perhaps the problem is your router. Try connecting your computer to the network via a wired connection, i.e. Without the presence of a router in a bundle.

So, if you threw a cable from the Internet to the computer and got access to it, the situation occurred definitely due to the router in which the settings were either changed, which led to the state of "IPv4 without access to the Internet", or something happened to himself device.

You can try to restore the factory router settings in its parameters that are available in most cases at the address. 192.168.1.1 (The address for setting is indicated on the device box or on its body). If you yourself conducted a router setting up, you know perfectly well what value there should be exhibited.

METHOD №5 Turning off / removal of antivirus

The duties of antivirus software include protecting your system from various malicious elements that are tirelessly trying to get into it and harm it. Some antiviruses coped perfectly with their duties, but others, so to speak, bend a stick.

If you have a third-party antivirus in the system, then try to disable it or even delete, since he could easily block your network connection. This rarely occurs (mostly antiviruses block some files, even systemic, but not connections), but still happens.

If the disabling / removal of the antivirus did not help return the Internet and "IPv4 without Internet access" still remains in place, you can also try to disable Windows Defender (irrelevant for Windows 7 users), system antivirus, which should have been activated after removal of third-party antivirus BY.

Method number 6 Disable Windows Firewall

Another reason that can stand for "IPv4 without Internet access" is Windows Firewall. This network screen can block your network connection. Now we will try to disconnect your firewall for a while and see what will come of it:

  • Right-click on the start.
  • Select "Control Panel".
  • Select "Windows Firewall".
  • Click on "Enable and disable Windows Firewall" on the left side of the window.
  • Put the ticks opposite the items that turn off the firewall for private and public networks.
  • Confirm the changes.

Go to the "Details" window of your network connection that can be found in the network management center and shared access, and see if there is a version of version 4 access to the Internet. If not, let's move on.

METHOD number 7 Set the address of the DNS server from Google

If you suddenly disappear access to the Internet, you can try to execute one defined, so to speak, a trick that sometimes helps to return your computer into the network. So, it is to set static addresses for the DNS server.

To do this, do the following:

  • Press the key combination Windows + R.
  • Enter an empty string nCPA.cpl And press ENTER to open the Network Connections window.
  • Find your network connection and click on it with the left mouse button twice.
  • In the Status window, click on the "Properties" button.
  • Select the "Internet Protocol version 4 (TCP / IPv4)" component, and then click on the "Properties" button.
  • Set the following addresses for the DNS server:
    • Preferred DNS server: 8.8.8.8.
    • Alternative DNS server: 8.8.4.4.
  • Confirm the changes and close the window.

Having placed static addresses for the DNS server instead of automatic, try again to look back to your Internet connection. Well, how, "IPv4 without access to the network" is still present. If so, we will now try to fulfill something that may help you return access to the Internet.

Method number 8 Static IP Address

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

That's what you need to do in order to set a static IP for your connection:

  • Press keys Windows + R.
  • Enter in the string nCPA.cpl And press ENTER.
  • Double click on your Internet connection.
  • Select your connection properties.
  • Select "Internet Protocol version 4 (TCP / IPv4)".

Here you have to set certain values. First you need to find out the address of your router (since this step is applicable to the owners of the wireless connection). For example, the most common address is 192.168.1.1., But it can be different. As already mentioned above, it should be written on a router box or on its body. Learning the address you need, follow these steps:

  • In the IP address string, you need to enter the address of the router, but only a bit changed. 192.168.1.1. →192.168.1.10. Add to the end of the address zero.
  • In the string of masks do not fit anything, because It will be exhibited automatically.
  • In the line of the main gateway, you enhance the familiar address of your router, for example 192.168.1.1.

Save Internet connection changes, and then check the ability to access the Internet and IPv4 problems without network access. Well, how to succeed? Still nothing. Well, in this case, you can specify a couple more not methods, but tips for this situation:

  • Perhaps the virus hit your system, which somehow could block your network connection. Check your system using an antivirus scanner.
  • The problem with the absence of the Internet and "IPv4 without Internet access" can be consisted on the side of your provider. Contact providers and find out whether there are some problems on his side.

Found a typo? Highlight the text and press Ctrl + Enter

If you encountered designation Network "Without Internet access" means that your network does not receive packages from outside. The question appears, and what to do and how to eliminate this problem? The universal solution does not exist, you will have to try each of the presented methods before finding out the cause and elimination of an unidentified network.

Possible problems of the provider

The first step in such situations is to call a service provider to find out if there is access to the Internet. On the side of the provider, technical works may be conducted or an unexpected breakdown. In order not to climb in vain, find out the involvement of the supplier.

Call the company's call center, look at the official website or page on social networks. As a rule, they write about topical issues. If the information is missing, look at the comments of other users. Perhaps you are not alone collided with the fact that the computer does not connect to the network. I do not solve problems with the provider, so it remains only to expect.

Cable or connector problems

Next, inspect the LAN cable. Make sure that the plugs are good, while do not have physical damage. Inspect the wire isolation and check if there are no beggars. You can try to replace the lan cable connecting the router and computer. If direct connection is used, then exit the partition and to the site by checking the wire along the entire length. If damage is detected, naturally call online managers immediately. They must send the wizard to replace the network cable.

Routher malfunctions

The second most common source of message appearance "without network access" is a router. The list of frequent problems belongs:

  • selection of incorrect connection type;
  • setting the wrong IP address or login password (when using ADSL, L2PT or similar connections);
  • there are any restrictions in the settings;
  • hardware problem (a capacitor sank or burned the board).

In the latter case, you will need only help professionals or buying a new modem. All software flaws can be eliminated independently subject to the fulfillment of correct action.

When there is no Internet access on the computer, restart the router and PC. During the operation of devices, minor failures may occur, which are not critical. Reboot allows you to eliminate these problems. On the computer, it is enough to click a button that is responsible for this function or select the corresponding menu item in the Start section.

With the modem is all easier: press the POWER button to turn off, and then turn on the machine. If there is no such keys, just pull the power supply outlet.

Settings in the web interface

The installation of incorrect parameters in the modem leads to the creation of a network without access to the Internet. The solution is quite simple: go to the web interface and set the correct parameters. Next, we will tell you in detail about these steps.

How to enter the web interface?

Connect to the modem through the lan cable directly. To log in to the system menu, you need to find out the data for authorization (login, password and address to which the transition will be performed). Find this data on the label glued to the device case. Fields are called IP Address, UserName and Password. On some models, they are translated into Russian.

The entrance is performed a couple of steps:

  1. Discover the browser on the PC (Google Chrome, Firefox, Opera or Standard). Write an IP address to the entrance and Clause Enter in the address bar.
  2. On the Authorization page, fill in the fields (the first is the username, and the second password). Click "Login".

You must get to the start page of the router settings.

Internet connection settings check

Most routers allow you to use multiple types of connectivity. For each of them require their own parameters:






Problems on a PC or laptop

Try connecting the router to other devices, such as a laptop. Correct work and the lack of error "No Internet access" speaks about problems in a personal computer / laptop that is used to access the Internet.

Diagnosis of problems

Windows operating systems have standard troubleshooting tools. They are not always able to return access, but often cope with contacts to the local network. To start the procedure, follow the instructions:


If the faults are not detected, run additional items ("Home Group" and "Network Adapter"). The system will analyze other parameters and may find faults there.

Setting up IPv4.

Despite the global transition to IP version 6, the classic IPv4 is used together, so the incorrect address of addresses can lead to access errors. You can configure the protocol via the operating system interface:


Also addresses can be requested from the provider. When using a static connection, you often need to set parameters in the OS itself.

Reinstalling the network card driver

For the correct operation of "iron" in the system, a special driver (specialized software) is used. After installing Windows, through its database, try to find drivers to independently put them, but not always successfully. The versions of the disk complete are usually outdated, so we recommend updating the driver via the Internet.

The first and most reliable method is to download the desired software from the manufacturer's website. Find the "Drivers / Utilities" or "Support" section, select your network card model and OS version. After download the installer, and then simply start it on the computer.

Alternative, but less efficient option - update through standard operating system functions:

  1. Right-click on the "My Computer" icon. Select the "Properties" string.
  2. On the left side of the window, click on "Device Manager".
  3. Find a network adapter. According to it, PCM and "update drivers".

You can also find specialized utilities created to search for topical versions of drivers on any "iron". Popular software is Driver Genius. The user is just enough to run scanning. The utility will find all the components that need update. The functionality allows you to update only the selected system elements. Soft comes in Russian.

Change MAC Address Network Card

Part of Internet providers uses connection with reference to the MAC address. This is a unique identifier that is assigned to any network equipment. At the hardware level, a regular user will not be able to change the mac address, since this requires programmers. However, you can change it at the program level, which is enough to connect to the network.

Change is performed according to the following instructions:


Please note that the MAC address consists of 12 digits in a 16-riche system. To check the correctness of the change in the console, enter the IPConfig / All command.

There is a second method of change through the registry. You need to go through the path of the network card, while changing the value in the NetWorkadress field for the corresponding component.

Check Firevol

The problem is why the Internet is not yet available, maybe in firewall. This is a built-in defender in Windows, which blocks unwanted connections. If there is an antivirus in the system, it can be safely disabled:


Cleaning the DNS cache and reset TCP / IP protocol settings

Errors may occur in files related to TCP or DNS stack. It is recommended to reset the cache for these components:




Enable FIPS Compatibility Mode

In some cases, OS Windows 7 or the newer will have to activate compatibility mode with federal FIPS standards:

  • Go to the "Condition" point of the adapter. Click the Wireless Network Properties button.
  • Next, go to "Advanced Parameters". Put the box next to "Enable Compatibility Mode ...".

If this feature is enabled, try to deactivate it.

If the cable goes to a PC directly (without a router)

With direct Internet connection, all methods are relevant to the computer with the exception of the router setting section due to the lack of the latter. We also recommend re-create a re-connection connection through the "Creating a new connection" item.

There is access to the Internet, but the error does not disappear

The reason for this situation is more often connecting through a proxy server. You need to get to the editor of local group policies. Click Through Starting "Run", and then enter the command specified in the image.

After that, activate the "Disable Active Sensing for the Network Connection" indicator. " In Windows 10, this parameter is called differently ("Disable active network connections performance checks"). At the same time, remember that with actual problems with access, information messages will not appear.

These are all current methods, how to get rid of an unidentified network. If you are new, while you do not have the experience of setting up the router or operating systems, we recommend contacting the specialist. Unprofessional intervention can only incur the situation.

At least once in your life, each computer user or laptop came across the problem of connecting and setting up the Internet on your device. One of such cases when when connecting an Ethernet cable (network cable) to a PC or connection to WiFi network, instead of computer access to the Internet, you get an inscription "Unidentified Network", and on the network connection icon, which is in the panel near the clock appears Yellow triangle with an exclamation mark.

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

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

Invalid network card settings - problem with IP address

It occurs if the network card was assigned an IP address and when connected to a new network, it cannot get another. To check this, follow these steps:

Step 1 Open Start menu and select Control Panel

Step 2 Find the program Network and Shared Access Control Center And launch it

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


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

Step 5 In the Connection Properties window, select Internet Protocol version 4 (TCP / IPv4) and click the Properties button that is located just below.

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

  • if you are connected to a WiFi network or use an Ethernet cable from the router, then check the ticks to automatically get the computer to get a new address
  • if you have connected the Internet cable to a direct computer, bypassing the WiFi router, and your provider provides Internet access to an IP address - Check the specified parameters (IP address, gateway and DNS servers addresses), you can see them in contract or contact the service provider

TCP / IP Problems

It occurs when the internal TCP / IP errors appear, for which the protocol settings are reset.

Step 1 Start the program Command line (cmd.exe) on behalf of the administrator

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


Step 3 Restart the computer

Network card drivers

It occurs when after installing a Windows driver for a network card automatically installs OS itself or you use the driver pack (Driver Pack). Often, this problem appears on laptops and to eliminate it, you need to install drivers from the official website of the laptop manufacturer or computer network card.

Problems with DHCP.

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

If you see the address of such a content in the IP address or master gateway line: 169.254.x.x. - So the system could not get an IP address automatically and the problem lies in DHCP.


In this case, do the following steps:

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


Step 2 Find a network adapter through which you try to connect to the Internet, click on it right-click and select Properties


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

Step 4 Select a parameter Network Address (Network Address) / locally administered address and in the field Value write 12 characters (use numbers from 0 to 9 and letters from a to f), then click OK

Step 5 Return back to the program Command line And enter the following values:

Ipconfig / Release
ipconfig / renew.

Step 6 Restart the computer and check if the error is eliminated in the section Type of launch From the drop-down menu, select Disabled, and in the section condition Click Stop button

Step 5 Now click OK and restart the computer.

We hope that at least one of the submitted tips will help eliminate the problem with an unidentified network on your computer or laptop.

There are several reasons for which Wi-Fi is without access to the Internet. Often the problems are concluded in routers and access points, but there are cases when the fault is the services installed in the operating system.

How to recognize the cause of the problem, read on.

Defining trouble

First you need to find out what kind of connection stage there was a problem. In order to make sure that the problem is to configure the router, you must try to connect to the Wi-Fi network through another Windows laptop or smartphone.

If the error disappears and connecting to the Internet is present on another device, the user learns that you need to configure the Wi-Fi adapter in the laptop itself.

In the case when access to the network was not received from any device, it will be necessary to look for problems in the router, point of access, modem or Internet provider.

You should also try to connect the network by means of a network cable, bypassing routers. This will determine the problems more specifically.

If you have access to the Internet on the cable, it is necessary to change the settings of the router itself or the access point, if not, the problem in the modem (if available) or provider.

Turning off access to the network on the side of the provider

Sometimes for the reasons for malfunctions or technical works, a yellow triangle can be observed, which is noticing the user about a limited Internet connection.

In the case when the equipment settings were not performed, but access, nevertheless, disappeared, most likely, the problem on the side of the provider.

In this case, it is necessary to find the phone number of the company, which is usually recorded in the contract, and by calling, to ask about the causes of malfunction.

Tip! But you should not immediately hurry to dial the operator of your provider, first reboot the router, as the technical support is exactly what will offer to be done first.

If the resource loaded and access to the personal account is obtained, this will mean that the Internet connection is intentionally limited by the provider, perhaps for non-payment.

In the case when the site does not work, it is worth moving to a call to the technical support operator.

Operating system settings

If access points are visible in the system on a laptop, reinstalling the driver will not be required.

When the Wi-Fi adapter is successfully connected to the network, but in the system tray there is a yellow triangle that prompts about a limited Internet connection, you must disable antivirus and Windows Firewall, which, with incorrect setting or failure in their operation, can cause a similar problem.

The optimal option for checking the Internet performance will be to load the system on a laptop in safe mode with network drivers.

To do this, you will need to go to the system settings by pressing the key combination in Windows "Win + R" and execute the msconfig request.

After that, the "System Configuration" window opens. It is necessary to go to the "Load" tab, where you need to note the "Safe Mode" with the "Network" parameter.

If you have access to the Internet with this option, you need to start a laptop in normal mode, removing the parameters installed earlier, and after, it turns off the applications that affect the operation of the network. Most likely, it can be recently installed or updated programs.

You must also scan a computer for viruses. Optimal for this option will be the Dr.Webcureit program! For Windows, as it does not require installation, free and always contains a relevant database.

Setting up router

If access to the Internet is missing on multiple devices, the problem is in the router settings, which incorrectly distributes the connection. It may occur when resetting the parameters installed for the current provider.

To restore them, it will be necessary to open a description of the configuration on the website of the company that provides the Internet. Also, all the necessary parameters for submission to the router are often attached to the contract concluded when connecting services.

In the event that the router was bought regardless of the provider, the instructions for it will most likely be present on the site. It will be necessary to find on the resource of the equipment manufacturer. Also, the documentation is always present in the box with a router.

Sequence of actions for making settings to the D-LINK DIR-600 router:

  • open the parameters by entering its IP to the Windows browser address bar or other OS;
  • enter the username and password (by default they have an ADMIN value);
  • in the Wireless Wizard, configure the name and password of Wi-Fi connections;

Name of network Wi-Fi

  • going to the tab in the lower horizontal menu "Advanced Settings", click on the WAN item located in the Network section;
  • if you have a connection profile, press it twice to make settings if it is missing added new.
  • in the window that opens, make and save the settings that are listed on the manufacturer's website.

Also, for this model of the router, a simpler setup option is available by pressing the Click'n'Connect item in the main menu. Nevertheless with some providers, he can not work correctly.

Access restriction on public routers

Coming into some in the coffee shop and connecting the laptop to Wi-Fi, you should not run programs to load torrents, since the network is automatically turned off and is no longer restored even after rebooting the router, the access will again open only after a day.

This restriction is established to ensure that visitors do not overload and without it is not too high-quality access to the Internet.

The installed traffic filtering system for a while adds the MAC address of your network Wi-Fi adapter on a laptop to a blacklist. But there is still a solution to such a problem.

Since we do not have access to the equipment of the coffee shop, only the option of replacing the MAC addresses on our equipment remains.

Windows MAC Address Change

Most equipment with Microsoft Windows operating system, the optimal version of the MAC address change is the registry editing. Despite visual complexity, it will not require a lot of time.

Creating a new parameter in the registry

  • create a string parameter in this folder named NetworkAddress;
  • by clicking on it twice, add the value of the new MAC address represented by 12 hexadecimal numbers (for example, "406186E53DE1");
  • reload Windows to apply settings.

After that, the adapter will no longer be in the blacklist, and therefore, it will be possible to perform a successful Internet connection.
conclusions

There are many problems and solutions for them. Finding out with what equipment there was a failure in the work, it will be possible to find the optimal way to correct the problem.
