Wifi sees but the Internet. Why Wi-Fi may not work on a laptop and how to fix it

WiFi is a unique wireless technology that is incredibly popular all over the world. Now there are very few people who prefer the usual wired Internet. Connecting and setting up Wi-Fi is not difficult. But even in such a perfect system, sometimes errors occur due to which the Wi-Fi stops working. The most common is a problem with connecting a Wi-Fi router.

Some people are faced with a situation where the router is connected to the network and works, but does not distribute: the computer cannot “see” available network. Why is it so? There may be several reasons for the occurrence:

lack of installed network drivers;

hardware type errors;

arbitrary shutdown of the connection to the computer - it is obvious why in this case the device does not work as it should;

malfunction of the wi-fi module;

WiFi router failure.

There are other problems, but the ones listed above are the most common reasons why the device does not work. Therefore, we will focus on them.

Problem with network device drivers

Testing the WiFi module driver is carried out in the "Device Manager". This section is located in the Start menu. You can also get to the section through the "My Computer" shortcut by pressing the right mouse button.

In the "Dispatcher" you can see all the devices connected to the computer. We will be interested in network equipment. You need to go to the branch with network drivers. If the branch is missing, it means that the drivers for the wifi adapter have not been installed on the computer.

If there is a branch, one of the network devices may have a “!” sign. This means either the absence or incorrect functioning of one of the drivers. Each of the problems is easily solved with a simple reinstallation of the software. Usually, the software is located on a disk attached to the computer. The wifi adapter for device manager might be called Wireless Network Adapter. Also, everything you need can be downloaded from the Internet using a mobile connection (if another is not available at the moment).

How to check the status of a wireless connection

If everything is in order with the drivers, then the next step is to check the wireless connection. It can simply be disabled. Testing is carried out differently on different operating systems. But it all comes down to one thing: you need to get into the "Network Control Center".

Exists universal way. You need to press Win + R, after which a window with a line will appear. In the line you need to type the command control panel and press Enter. This will open the Control Panel. Here we go to "Network and Internet", then to the "Network and Sharing Center". In the "Center" we will be interested in the section "Change adapter settings", located on the left. Clicking there will allow you to see the status of all connections that are available on the computer.

"Wireless connection" - that's what will be important to us. If the label is not colored, but gray, this means that there is no signal. You can start the connection by double-clicking the left mouse button. After starting, the computer starts searching for all available connections.

If they do not appear, then you can try to perform system diagnostics. It is carried out through the "Network Control Center" and the item "Change adapter settings". On the label " Wireless connection” must be right-clicked. In the window that opens, click the "Diagnostics" field. The computer conducts the test itself. Based on the result of the check, the user receives advice on what to do next.

What to do if a hardware error occurs

A hardware error would indicate a problem directly within the network card. In a word, if the computer does not see the adapter for connecting to Wi-Fi, it means that this Wi-Fi device is not functioning. There are two main reasons:

the device is broken;

there was a problem with wifi drivers.

The second option has already been described by us. However, if Wi-Fi drivers are available, and the computer continues to not see the adapter, this means a breakdown. One of the most common causes of failure is the combustion of the device.

The cause of combustion may be overheating if the computer has been operating at its maximum capacity for a long time. If we are dealing with a laptop, then this happens even more often here, since many users forget the device on a soft surface that blocks access to the hole through which cooling air enters. This problem is solved by simply replacing components with similar ones.

It should be borne in mind that the lack of experience in independent manipulations with computers can lead to even more harmful effects. This is especially true for laptops that have more complex structure. the best way out from the situation there will be an appeal to the service center, they will accurately determine the reason why the device does not work.
Hardware-type connection errors also include a disconnected antenna. Most often, this problem occurs in laptops or desktop computers that have been cleaned or repaired in some way. The specialist who carried out the procedure could simply forget to connect the device, or he connected it incorrectly. This makes it impossible for the adapter to function normally, which does not work normally and cannot normally catch the signal distributed by the router, even when it is near the source.

A rather rare case is the clogging of the antenna terminals with dust. This breaks the internal contact. The solution to the problem is cleaning.

Why Wi-Fi router does not distribute the Internet

The connection problems described above refer to malfunctions in the computers themselves. But often there are problems that are related to how the router works (or rather does not work) and does not distribute the Internet.

There are two main problems:

inability to establish a wireless connection;

no access when connected.

These failures can be easily solved on your own, without resorting to the services of specialists.

How to solve a problem with connecting to a wireless connection

Testing how the router works begins with checking the status of the indicators that are located on the external panel of the router. During normal operation, the LED next to the antenna pattern will be either solid or flashing. If there is no glow at all, it means that the wireless module is not running on the router. On certain models, there is a separate button that one of the family members can accidentally turn off.

The lack of a button makes it a little more difficult to solve the problem. You need to go to the "Wireless Network" section located in the web interface of the router. In the English menu, this section is called "Wireless". There is a checkmark next to the "Enable" box (in English - "Enable"). A mouse click may solve the problem.

It is possible that when the device does not distribute the Internet, the malfunction is related to the radio channel used. Most router models have an automatic configuration function. If it is missing, you can try to install the 1st or 6th channel. They should be suitable for our country.

It happens that it becomes impossible to connect to wireless network, as the network issues a message about the incorrectly typed password. It is worth checking the security settings in the web interface. The set encryption type must be AES. The general security standard is WPA2-PSK.

How to solve the problem if there is no access while connected

Quite often it happens that the connection starts, but the process itself takes a long time. The status shows the message "Obtaining IP". After a while, the connection is dropped.

This means that network clients cannot obtain an address due to a disabled DHCP server. You can check this through the settings on the local network. You will need a LAN section, where there should be a checkmark next to the DCHP parameter.

Access problems may occur due to incorrect operation of DNS servers. Incorrectly assigning them to network clients or not assigning them at all, as well as unstable servers, are the three main reasons.

The solution to the elimination problem is as follows. You need to use public DNS. They are provided by Yandex and Google. In the first case, you need to set 77.88.8.8 in the settings, and for Google this value is 8.8.8.8. Data is entered on the computer in the properties of the Internet protocol of any version of TCP/IP.

Conclusion

All of the above are troubles that you can get rid of on your own. In any other situations, it would be better to contact the provider's technical support or professional craftsmen.

Everything is fine, the laptop connects to Wi-Fi, but it says that without access to the Internet or the network is not recognized in Windows 10, 8 and Windows 7? A common problem and now we will analyze in detail possible options solutions. It should be noted here that the main reasons for the appearance of this situation are errors when setting up the router, a router that is not configured at all, something is wrong with the Internet provider, problems on the connected computer, laptop or other device. All this in order and consider.

The very first thing to do, even before checking all the options below, is to go to the router's web interface and see if your provider's connection is connected. If yes - most likely, something is wrong with the connected device. If not, there is a problem with the router, wire, Internet. This is not necessarily the case, but it is better to start with this.

Option 1. The Internet does not work at the provider or the router needs to be rebooted

You should pay attention to this option if before that you have the same WiFi router everything worked. To get started, try simply unplugging the router from the outlet and plugging it back in - there is a high probability that everything will work. A wireless router is also a kind of computer, and therefore it can freeze and behave not quite normally.

If rebooting the router did not help, go to the router settings (how to do this is described in each instruction for setting up the router on this site, open any one that matches your device model) and check the connection status. It is possible that the problem with the Internet is with the provider itself and you just need to wait until everything is fixed. It may also be that for some reason the router settings have been reset (this also happens), in which case it will have to be configured again.

Option 2. You haven't configured your router

Often you have to deal with the fact that a novice user has connected the wires to the router (connected correctly), launched the Internet on a desktop PC - everything works. And it connects from the phone and tablet - the sites do not open, on the laptop it says that without access to the Internet.

I explain: the fact is that the router must be initially configured, and the fact that the Internet is connected on the computer does not mean anything (after setting up the router on the computer, you do not need to start it at all, as this can lead to the problem described in this article). And the phone and laptop will connect to Wi-Fi in any case - for this you can simply plug the router into a power outlet without connecting wires, that is, this also does not mean anything.

So, if you did not set up the router or set it up according to the instructions in the box, then find the instructions for your provider and model on the Internet (for example, on this site) and set it up. If you set it up, do not start the Internet connection on the PC (if you previously launched a separate icon for Beeline, Rostelecom, Dom.ru, the Aist program or something like that).

Option 3. There is no Internet on a laptop when connected via Wi-Fi

And now about laptops. It happens that everything works on other devices, but not on a laptop. The status of the router says that the provider's connection is connected. In this case, first check the wireless connection settings on your laptop, for this use, only do all the steps for your Wi-Fi connection.

After that, especially if you have an unidentified network without access to the Internet via Wi-Fi in Windows 10, try to remove the existing Wi-Fi drivers on the laptop (those that Windows 10 most likely installed itself) and manually install the Wi-Fi driver from the laptop manufacturer's website for your model (and not through the "Update driver" in the device manager). In general, the same method is suitable for Windows 7 and 8 (8.1) - if you installed some “assemblies” and now the Internet via Wi-Fi either works, then it doesn’t, or it doesn’t work all the time.

Every user of the global network sooner or later faces the problem of accessing the network. There are many reasons, both software and hardware, for which network access suddenly stops. In the article, we will consider such a common error specific to Windows as - "Unidentified network without access to the Internet."

Any difficulty regarding the Internet and any network in general can arise for one of two main reasons - through the fault of network equipment or through the fault of software. An error like "Unidentified network without access to the Internet" is usually the result of malfunctions in the software part of the computer or communication devices. This includes the actions of malware that block the network, incorrect settings for the network services of the operating system, PC network equipment or external communication devices (wired or Wi-Fi router, modem, or even provider equipment).
A similar message means that at the moment the computer has a connection to some network, but does not have access to the World Wide Web. An existing network is a connection, for example, through a wired router or another computer, WiFi networks, as well as to the provider's equipment (if the computer or laptop is connected to the Internet via a cable that comes into the room).
We will try to figure out why this happens, and also give solutions on what to do in a similar situation.

ISP related issues

If the PC is connected via a network cable that comes into the room from the outside, then access to the global network is most likely blocked due to the fault of the provider. The reason may be a situation with equipment malfunctions on the provider's side - a short-term malfunction, incorrect hub settings, lack of equipment connection with the provider's server (possibly due to a broken cable connection). But in such cases, there is nothing left to do, except how to wait for troubleshooting from the provider's side.

A similar problem can occur due to the blocking of Internet access by the provider due to the expiration of the subscription fee or the deliberate termination of the provision of services (this happens, for example, in the case of DDoS attacks on the server from the client’s computer). The last case of disconnection is, of course, very rare, but still possible.

In the last two cases, the laptop will also be connected to the network (provider equipment), but also without access to the World Wide Web. That is why Windows writes to the user "Unidentified network without access to the Internet."

Network settings

If there is accurate information about the performance of the provider's equipment and the absence of blocking on its part, then the problem most likely lies in communication devices (for example, a Wi-Fi router), local network settings or in the settings of the OS itself. All this can be checked directly from the computer.

If in your case a wired or WiFi router is used as a communication device, the problem may be hidden in the incorrect settings of the ipv4 protocol. You can fix them as follows (further actions are recommended in any case, especially if Internet access is via a local network through a router):

Now your laptop or computer should display information about the successful connection to the network. If the Internet is available, Windows will write in the "Network Control Center ..." section in the "Access Type" item - "Internet".

But what if Windows continues to write about the lack of connection? Open the IPv4 protocol properties window again, and change the value of "0" in all fields to "1", as here:

The last step must be done for cases where the standard factory address of a wired or Wi-Fi router is different from "192.168.0.1". If this address was changed by you or other users on your own, we recommend that you find it and add the necessary data to the IPv4 properties.

For example, if your Wi-Fi router, which connects to a PC via a local network, has an IP address of "192.168.1.55", then in the IPv4 settings in the "IP address" section you must specify, for example, 192.168.1.10, and in "Default Gateway" and "Preferred DNS Server" change the last two digits to 1 and 55, respectively.

Does the laptop still say "No network access"? Then the Internet disappeared, most likely due to the settings of a wired or Wi-Fi router. But here, too, there is a possibility that your laptop is having difficulty connecting due to a failure in the network settings of the system. It can be fixed.

Reset network settings

If the PC writes a message about the lack of Internet due to a network settings failure, then they can be returned to their original state by performing a few simple steps:

Windows also writes a message about the lack of access to the World Wide Web if the wired or Wi-Fi router has incorrect settings. There is a similar problem in the case when the laptop is connected to the Internet directly via a cable. If you have suspicions about this, then there is nothing left to do except call a specialist to set up your computer (but most likely you will have to set up a Wi-Fi router).

The complexity of describing this problem within the framework of one article lies in the fact that the provider can provide access to the network using one of several communication technologies - for example, ADSL or VPN. To connect a laptop or computer to the Internet, you need to ask the provider for the data for the settings, which, in most cases, are individual for each user and case. But to describe them all is time consuming, so in such situations it is better to turn to specialists.

In contact with

There are several reasons why there is Wi-FI without access to the Internet.

Often problems lie in routers and access points, but there are also cases when services installed in the operating system are to blame for the malfunction.

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

Determining the problem

First you need to find out at what stage of the connection the problem arose.

In order to make sure that the problem is with the router settings, you must try to connect to the Wi-FI network through another Windows laptop or smartphone.

If the error disappears and the Internet connection is present on another device, the user will find out that it is necessary to configure the Wi-FI adapter in the laptop itself.

In the event that access to the network was not obtained from any device, it will be necessary to look for problems in the router, access point, modem or Internet provider.

It is also worth trying to connect the network using a network cable, bypassing routers. This will allow you to identify problems more specifically.

If there is access to the Internet via cable, then it is worth changing the settings of the router or access point itself, if not, the problem is in the modem (if any) or provider.

Disabling network access on the provider side

Sometimes, for reasons of malfunction or maintenance, a yellow triangle can be observed, which notifies the user of a limited Internet connection.

In the case when the equipment settings were not performed, but access, nevertheless, was lost, most likely the problem is on the provider's side.

In this case, you need to find the company's phone number, which is usually recorded in the contract, and, by calling, inquire about the causes of the malfunction.

Advice! But do not immediately rush to dial the operator of your provider, first reboot the router, since technical support will offer to do this in the first place.

If the resource has loaded and access to Personal Area received, this will mean that the Internet connection is limited by the provider intentionally, possibly for non-payment.

In the event that the site does not work, it is worth going to a call to the technical support operator.

Operating system settings

If access points are visible in the system on a laptop, you will not need to reinstall the driver.

When the Wi-Fi adapter is successfully connected to the network, but there is a yellow triangle in the system tray, indicating a limited Internet connection, it is necessary, which, if configured incorrectly or if they fail to work, can cause a similar problem.

The best option for checking the health of the Internet is to boot the system on a laptop in safe mode with support for network drivers.

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

This will open the System Configuration window. In it, you need to go to the "boot" tab, where you need to mark "safe mode" with the "network" parameter.

If with this option you have access to the Internet, you need to start the laptop in normal mode, removing the previously set parameters, and then turn off applications that affect the network one by one.

Most likely, these may be recently installed or updated programs.

The best option for this is Dr.WebCureIt! For Windows, since it does not require installation, it is free and always contains an up-to-date database.

Setting up a router

If Internet access is not available on several devices, the problem is in the settings of the router, which distributes the connection incorrectly.

It can occur when resetting the settings for the current provider.

To restore them, you will need to open the description for setting up on the website of the company that provides the Internet.

Also, all the necessary parameters for entering into the router are often attached to the contract concluded when connecting services.

In the event that the router was purchased independently of the provider, the instructions for it, most likely, will not be present on the site.

It will need to be found on the resource of the equipment manufacturer. Also, the documentation is always present in the box with the router.

The sequence of actions for making settings on the D-Link DIR-600 router:

• open the parameters by entering its IP into the address bar of a Windows browser or other OS;

• enter your username and password (the default value is admin);
• in the wireless network wizard, configure the name and password of the Wi-FI connection;

Name WiFi networks

• by going to the tab in the lower horizontal menu "Advanced settings", click on the WAN item, located in the network section;
• if there is a connection profile, double-click on it to make settings; if it is missing, add a new one.

• in the window that opens, make and save the settings that are specified on the manufacturer's website.

Also, for this router model, a simpler configuration option is available by clicking the Click’n’Connect item in the main menu.

However, it may not work correctly with some providers.

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

Microsoft operating systems, starting with Windows 7, constantly monitor network connections, and as soon as the global network is unavailable, they immediately report it. There are many reasons why a computer may not be connected to the Internet. These may be problems with the provider, incorrect configuration of the equipment by the user, or failures in the operation of network protocols. Today, the new IPv6 protocol is becoming more widespread, but its percentage is still quite small, especially in home networks, so the focus will be on the old version - IPv4.

Connecting through a router via a network cable without access to the Internet

Provider problems

Yesterday everything worked, and today this warning appeared. If this happened to you for no apparent reason, then in most cases the problem is with the provider. Therefore, before doing anything yourself, call technical support. Most often, data transmission lines are damaged, some technical work is being carried out, or you simply forgot to replenish your account on time.

Perhaps you will hear in response that everything is working well for the provider, then you need to check your network and, if necessary, configure it. The support service will certainly offer the services of its own master, but, firstly, its services are not free, and secondly, while the master gets to you, you can manage to solve the problem yourself.

Physical connection problem

It is not so rare that the cause is a partially broken network cable or a loose connection in the connector. And if you have pets or children, then the likelihood of this development increases. Even Wi-Fi users should not forget that a cable is also stretched to the wireless router. Check the integrity of all wiring - if there are any strong kinks anywhere, if all the plugs are firmly inserted into the sockets and if they are inserted where they really need to be. Provided that the problem is not found here, we proceed to the next step.

Windows 7 LAN connection without internet access

It happens that the installed router hangs corny. In this case, it helps. To do this, just turn off the power to it and reconnect it after a few seconds. It does not hurt to restart the computer at the same time. If it happens that these router freezes occur with annoying regularity, consider buying a new device. It is also necessary to try to connect the Internet cable directly to the PC or laptop. If there is no result, first we will deal with the computer.

Checking computer settings

It is possible that the problem arose “out of the blue”, then there should not be any questions with the settings on the computer, much more often the problem occurs during the initial configuration or making any changes to an already working network. First of all, you need to check the correctness of the IP address of the computer, for which press Win + R on the 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 the case of using Wi-Fi). Right-click on the desired connection and go to properties, where the list will contain lines with IPv4 and IPv6 entries. Check the box next to IPv6, and double-click on IPv4. Check the boxes for automatically getting settings and save the changes. If access to the Internet does not appear, go ahead.

Setting up a LAN connection in Windows 7

Finding out the address of the router

Perhaps, nothing had to be done 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 only 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 IP of the router from the documentation for it, or it is indicated on the device case, and most often it is 192.168.0.1 or 192.168.1.1. Open your browser and enter the set IP in the address bar, and if it is correct, you will be prompted to enter login and password.

"Internet Protocol Version 4 (TCP/IPv4)" Properties

Setting up an internal network on the router

After entering the credentials correctly, you will be taken to the router control panel, and further actions depend on the device model and its firmware. You need to find a DHCP server management that is responsible for automatically obtaining IP addresses and other parameters necessary for the network to function properly for devices. Look for blocks whose names say DHCP settings, DHCP server, or the like. The block will contain a radio button with values ​​Enable or Disable. Most often, these settings are located in the LAN (Network) section. Enable the DHCP server, save changes and reboot the router. After this, the computer will be connected to the Internet.

Check your ISP connection settings

Do not jump to conclusions if the previous steps did not help you set up a connection. Since the network is still not working properly, we check the connection with the provider, for which go to the appropriate section in the router control panel. Almost all manufacturers call these options WAN or Internet. There are quite a few options in this section. Which are intended for you, you can find out from the contract or in the technical support of your service provider.

Reinstalling network card drivers and checking firewall

It makes sense to do this when you are sure that all the 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 driver from the manufacturer's website, for which it looks like you have to go to a friend or neighbor. In the absence of such an opportunity, the driver that is included on the installation disk is quite suitable. Be sure to restart your computer after reinstallation. It should also be noted here driver failures that occur due to installed software that changes the operation of network protocols on a computer. The most common representatives are antiviruses and firewalls. Make sure that such programs are not installed, and if they are, then disable or remove them during the check, 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 excluding it. On your computer, go to Device Manager by pressing the Win+R keys, typing devmgmt.msc and clicking OK. The device manager will start, where you need to find the "Network adapters" section, expand it and select the network card with which the PC is connected. After double-clicking on it, in a new window, on the Advanced tab, select the Network address option and enter any twelve digits in the empty field on the right. After that, we 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 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 the entry by pressing Enter. After working out each command, restart the 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 they will have to be configured again!

Flushing the DNS Cache Using the Command Line

You have a direct connection to an ISP

The option when your computer is connected directly to the provider, bypassing the router, is now becoming less common, as the number of network devices is steadily growing. But what if you have just such a connection? Eliminate possible problems with the drivers as described above, and check that the connection settings are correct. Regarding settings, the best option will contact technical support, since there are a lot of variations.

Nothing helped at all.

Maybe you are lucky and your ISP provides access using the new IPv6 protocol, the configuration of which requires some knowledge of the 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 the efforts were spent, and your network did not work, then there is only one advice - call the wizard. It is quite possible that the problem that has arisen is non-standard or the replacement / repair of equipment is required to solve it.

There is Internet access, but the error remains

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

Conclusion

This article collects the most common problems associated with the "Network without Internet access" error and suggests ways to solve it. We hope that the material was interesting for you and helped you to overcome the difficulties that have arisen on your own.
