Why is there no Wi-Fi connection? The laptop is connected to Wi-Fi, but the Internet is not available - solution. Reconnecting to the network

If devices connect to the Wi-Fi network, but the Internet does not work, you need to determine the reason. The problem may be in the Internet connection itself, in the router or laptop (or other connected gadget).

First you should check if the Internet is working at all. To do this, the network cable is connected directly to the computer. If the Internet connection does not appear, you should contact your provider. Otherwise, check the settings of the router and devices connected to the wireless network.

To understand that the problem is not in a specific laptop or other connected gadget of the user, you need to connect other devices to the router, such as a phone, tablet, etc. If other devices find Wi-Fi, but after connecting the network without access to the Internet (this is indicated on a laptop), sites do not load, then the problem lies in incorrect router settings. If the connection is successful on other gadgets and the sites load, then the problem is in the connection of a specific device.

How to solve a problem with a laptop, smartphone, tablet.

If only one device says “Unidentified network, without Internet access“, you need to double-check the settings wireless connection to the network. When setting up the router, the user could accidentally change the connection data. You can check that the settings on your laptop or computer are correct as follows:

1. You need to connect to Wi-Fi networks.

2. Go to the Network and Sharing Center.

3. B open window In the right panel, click “Change adapter settings.”

4. In the open window, right-click “Wireless Network Connection” and select “Properties”.

5. In a new window, select “Internet Protocol version 4 (TCP/IPv4)” from the list and click “Properties”.

6. In a new window, see if the “Obtain an IP address automatically” and “Obtain DNS servers automatically” items are selected. If necessary, mark them and click OK.

7. Reboot the OS. After rebooting, the Internet connection should appear. If the network, as before, does not have access to the Internet, the connection may be blocked by antivirus programs or firewalls. Then you should turn them off.

How to solve a problem with a router.

Before setting up your router, you must first return to factory settings. To do this, press the button on the back panel of the router and hold it for 10 seconds. After this you need to go to the admin panel. To do this, enter the following address in any Internet browser: http:// or http:// (TP-link, Dlink). In the window that appears, enter your username and password to log in, usually admin and admin. To fix the router, you will need the WAN tab. Here you set up an Internet connection that connects to the router. SND providers use Dynamic IP, Static IP, L2TP, PPPoE, PPTP connections.

For example, Kyivstar uses Dynamic IP; the corresponding settings are set in the WAN section of this provider. If the provider uses a different connection, for example, Static IP, then the setting with Dynamic IP will not work; the router will not connect to the Internet in this case. To put correct settings, you need to find out exactly what connection technology the provider uses. This information can be checked with the provider itself or viewed on the Internet.

Sometimes providers create a binding to the MAC address, which can also affect the operation of the router. In this case, you need to connect the router via cable to a computer whose MAC address is registered with the provider, find the MAC Clone tab, click Clone MAC Address, and then Save.Update.

There are also situations of the following nature. The user decided to change the Windows 8 OS to the Windows 7 OS. Before the reinstallation, everything worked fine, but then problems began with connecting to the wireless network, the message “Unidentified network” appeared, that is, the Internet stopped working. To solve this problem, you need to go to the Network and Sharing Center, select Manage wireless networks.

Right-click on the network that you cannot connect to and select Properties. In the Security tab, click on the Advanced settings section. In the menu, check the Enable compatibility mode for this network Federal standard information processing (FIPS). This update should help resolve the connection issue.

Transferring data without using cables literally not so long ago seemed like something out of science fiction, but today wireless network WiFi at home, at work or in the nearest cafe no longer surprises anyone. But even with such a connection, some problems may occur. Connection error is a phenomenon that occurs quite often. Let's look at the most common problems and the simplest methods for eliminating them.

Wireless network connection: no connection. What is the reason?

As for the most common reasons, they can be divided into two main types: hardware problems (non-working hardware) and software errors.

In the first case, as is already clear, you need to carry out a full diagnosis of the equipment, and then make a decision on repairing or replacing it (this applies to network cards, routers, mobile devices, and external or internal Wi-Fi modules). In the second case, there are several situations where there is no wireless network connection (no connection). Among the main ones are the following:

  • disabled module or ;
  • incorrectly entered password;
  • router problems;
  • incorrect connection settings;
  • missing, incorrectly installed or outdated network device drivers;
  • lack of an established network;
  • exposure to viruses.

Problems with viruses, for obvious reasons, will not be considered, since any user must take care of protecting their system on their own. We will partially touch on the absence of a network, if for some reason it was installed in the system, but then disappeared (this, unfortunately, also happens). Finally, we will not dwell on the fact that the user may have forgotten or entered the WiFi network password incorrectly, and problems on the part of providers. These situations are not so significant in our case.

Wireless network connection: no connection. What to do in the simplest case?

First, let's look at the simplest situation. Let's say that at some point the wireless network connection is lost. The reason may be a short-term software glitch. What do most users usually do in such cases? They simply reboot the system (after all, everything worked before).

If this does not help, and the time of signal loss is known at least approximately, one of the options for solving the problem that a connection error appears when trying to connect to an existing network can be to simply roll back the system to its previous state through the corresponding section of the “Control Panel”. But, as practice shows, the problem is usually much deeper.

Diagnostics of connection using the system

If for some reason the Wi-Fi wireless network connection disappears, you can find out the reason using Windows tools. If you call up the menu by right-clicking on the network icon in the system tray, you can use the troubleshooting tool in it.

The system will independently carry out the analysis and then produce the appropriate result. Please note: this tool does not fix anything, but only helps determine the essence of the problem.

Checking Wi-Fi module activity

Many experts cite user inattention or negligence as one of the most common reasons for lack of communication.

For the most part, this applies to owners of laptops that do not have a special switch to activate the built-in Wi-Fi module, and turning it on or off is done by using a combination of a key with a special Fn button. It is clear that even when typing using the so-called hot keys, it was possible to easily and completely accidentally turn off the adapter. Therefore, first you need to make sure that it is in active mode.

Resetting your router

Sometimes the reason that there is no wireless network connection (no connection) can be a short-term malfunction of the router. This situation is most often observed with inexpensive routers of the TP-Link series.

And in this case, it is recommended to use the simplest reset method. You can do two things: either completely turn off the power for about 10 seconds, or press the special reset button on the back of the device and hold it for 30 seconds.

Identifying Network Settings

Now, if it is not detected, let's look at the basic network settings. To view them, you should enter the network and sharing management section from the “Control Panel” or from the click menu on the network connection icon and use the section for changing parameters

Here you need to find the TCP/IPv4 protocol (if IPv6 is not used) and click the properties button. As a rule, most providers provide services for automatically determining parameters, which should be recorded in the settings. It is worth paying attention to the fact that the use of a proxy server for local addresses must be deactivated (unless otherwise provided). Otherwise, you just need to enter all the parameter values ​​in accordance with the settings provided by the provider when connecting.

Correcting connection parameters on the router

If after this the connection problem remains, it may be due to the settings of the router itself.

Just in case, it’s worth entering the router settings menu through any web browser by entering the appropriate address (192.168.0.1 or 1.1), then in the section wireless connection(usually Wireless) make sure it is Enabled.

Troubleshooting driver problems

Another network problem may be that the network card drivers are missing, incorrectly installed, or outdated in the system. You can make sure that the device is not working in the “Device Manager”, which can be called either from the “Control Panel”, or from the computer administration section, or from the “Run” menu using the devmgmt.msc command.

A non-working device will be marked with a yellow marker. This is a direct indication that something is wrong with the driver. But it also happens that it is not displayed among problem devices. This is only due to the fact that the system installs the most suitable driver for it, considering it optimal.

In any case, it will have to be reinstalled or updated. This can be done directly from several menus. It is recommended that you first completely remove the old driver, and only then install a new one, but do not choose from what the system offers, but find the latest software for it in advance. of this device in the Internet.

To avoid doing such things, it is better to install a program like Driver Booster, which will find and install the latest drivers for absolutely all devices. It is clear that to do this, you will have to go with your laptop to the same cafe where there is a connection, and there use the WiFi password to enter the network (after all, there is no connection at home). The update process will take a maximum of 10-15 minutes, after which a reboot will follow.

Reset settings from the command line

If the network is still detected, you can still try the following steps. Calling command line with admin rights (cmd in the “Run” console), after which we enter the command proxycfg -d, and after pressing the enter key, two more - net stop wuauserv and net start wuauserv (after each - also “Enter”). These simple steps can also help.

If the network is not detected at all...

Finally, the last problem, when it is absent It is quite possible that due to some reasons, including the impact of viruses, the previously created network was simply deleted.

In this case, you need to go to the section for managing shared networks and make sure that the wireless network appears in the list available connections. If there is none, you will have to create it again by selecting the appropriate item. It will take a minimum of time.

If there is a network, but all the above methods for fixing the problem do not help, you can simply try to delete it entirely, then create it again and make the appropriate TCP/IP protocol settings.

Conclusion

In conclusion, it remains to add that these are only the main, most common problems and methods for solving them, which any user can use to resolve failures. Various types of commands that allow for complete testing of IP connections or assigned MAC addresses, pinging, etc., were not specifically considered here, since they may seem quite complicated for ordinary users to understand. In other cases, even the simplest remedies will help. However, this in no way applies to cases where the equipment fails. No software methods will help here, no matter how hard you try.

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. This "No Internet access" when, after connecting to a Wi-Fi network, the Internet does not work, and a yellow triangle with exclamation point. And if you hover your cursor over this icon, the message “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 becomes 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 can appear when connecting to the Internet via a network cable or Wi-Fi, in this article we will deal with connection via wireless wifi networks. As for problems with accessing the Internet via cable, I will also write in a separate article so that the instructions are simpler and clearer, and you don’t get confused.

This means that if you have a Windows 7 laptop, you are connected to your Wi-Fi router, and you have a connection without access to the Internet, then you have come to the right 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 reason?

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 that 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 the laptop, router, or Internet provider. Then you can do something to solve the problem.

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

  • Many people have this The problem appears during the router setup process. If you are setting up your router, it seems like you have already set it up, you 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 router settings. Most likely, you have incorrectly configured the router to work with the provider, take a look. Find instructions on how to set up your routea on our website, or write in the comments, I’ll try to tell you where to look for these settings. Connect other devices to the Internet (if possible), check if they work.
  • If you have such a problem with Wi-Fi suddenly, the Internet was working and suddenly stopped, or after turning it off/on, then first of all, restart your computer (laptop) and router. Then, connect again. Perhaps this will solve the problem.
  • Check Is the cable from the provider to the router connected correctly? whether it is inserted well into the WAN connector. I had a case when the Internet did not work for relatives - “Without access to the Internet.” Everyone was without the Internet for a week. 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 worked.
  • Make sure that your internet is paid for. Perhaps your provider simply turned off your Internet for non-payment.
  • Determine what the problem is: in a laptop, router, or Internet provider. It's not difficult to do this. 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 connecting the Internet directly to the computer into the network connector. Bypassing the router. If the Internet works, then the problem is most likely in the router. You can also call your provider and ask if they have problems in your area. I will write again 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.

Now that we have sorted out the most important points, we can move on 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 works on other devices, but not on your computer, then most likely the problem lies there. It would be nice to immediately try connecting it to other networks and see how it works. If the problem with the Internet via Wi-Fi on Windows 7 suddenly appeared, then try to remember, maybe 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 automatic receipt these parameters if you have static data specified. I already wrote about this in an article. Let's try.

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

Right click on the adapter Wireless network connection and choose Properties. In the new window, highlight the line "Internet Protocol Version 4 (TCP/IPv4)" and press the button Properties. If you have automatic IP and DNS acquisition set there, then set static parameters, as I have in the screenshot below. Your IP and Default Gateway may be different. It depends on the IP address of your router (you can see it on the sticker on the router itself). Maybe IP 192.168.0.50 (50 - this number can be set to another, for example, 100). We set DNS: 8.8.8.8 And 8.8.4.4 .

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

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

Another solution: enabling Federal Standards Compliance (FIPS) mode

Click on the Internet connection icon in the notification bar, then right-click on your Wi-Fi network that you are connected to (and with which there are problems), and select Properties. In the new window, go to the masonry Safety, click on the button Extra options, and check the box next to Enable Federal Information Processing Standards (FIPS) compliance mode for this network.

Click Ok, and restart your laptop.

How else can I try to fix this error in Windows 7? You can also disable your antivirus, firewall, and other programs that may block the connection. If all else fails, you can also update the driver for your laptop’s Wi-Fi adapter; there is some information about this.

How to fix if the problem is in the router or Internet 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 is wrong with the equipment, they are doing some work, etc. Or you just forgot to pay off 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, and it turned out that this was a problem with the provider.

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

Check everything thoroughly, reboot the router.

If this does not help, and especially if the problem arose during the process of setting up the router, then you need to check the WAN settings. Simply put, Internet settings. Most often, the “No Internet access” error appears when the router cannot connect to the provider, which is why there is actually no Internet access. But it cannot connect to the provider, most likely because the connection parameters in the router settings are incorrectly set.

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

I think you can find instructions for your router manufacturer.

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 were able to remove this error and the Internet is working on your laptop. You can ask your questions. Describe the problem, attach screenshots, I will try to answer quickly and help with advice.

There are several reasons why there is Wi-FI without Internet access. Often the problems lie in routers and access points, but there are also cases when the fault is caused by services installed in the operating system.

Read on to find out the cause of the problem.

Problem Determination

First you need to find out at what stage of the connection the problem arose. To make sure that the problem lies in the router settings, you need to try connecting 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 know what needs to be done Wi-Fi setup adapter in the laptop itself.

In the event that access to the network was not obtained from any device, you will need to look for problems with the router, access point, modem or Internet provider.

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

If you have access to the Internet via cable, then you should change the settings of the router or access point itself; if not, the problem is with the modem (if available) or the provider.

Disabling network access on the provider side

Sometimes, due to malfunctions or technical work, you can see a yellow triangle, which notifies the user of a limited Internet connection.

In the case where the equipment settings were not made, but access was nevertheless 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 written in the contract, and call and ask about the reasons for the malfunction.

Advice! But don’t immediately rush to dial your provider’s operator; first reboot the router, since technical support will suggest doing just that first.

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

In the event that the site does not work, you should call the operator technical support.

Operating system settings

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

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, you need to disable the antivirus and Windows firewall, which, if configured incorrectly or malfunctioning, can cause a similar problem.

The best option for checking the functionality of the Internet would be to boot the system on the laptop in safe mode with support network drivers.

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

After this, the “system configuration” window will open. In it you need to go to the “boot” tab, where you will need to check “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 installed parameters, and then, one by one, disable applications that affect the operation of the network. Most likely, these may be recently installed or updated programs.

You also need to scan your computer for viruses. The best option for this would be the Dr.WebCureIt! For Windows, since it does not require installation, it is free and always contains an up-to-date database.

Setting up the router

If Internet access is not available on several devices, the problem is in the settings of the router, which is distributing the connection incorrectly. This may occur when resetting the settings for the current provider.

To restore them, you will need to open the setup description 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.

If the router was purchased independently of the provider, the instructions for it most likely will not be present on the website. You will need to find it on the equipment manufacturer's website. Also, documentation is always present in the box with the router.

Sequence of actions for making settings on D-Link router DIR-600:

  • open parameters by entering its IP in the address bar Windows browser or other OS;
  • enter your login and password (the default value is admin);
  • in the wireless network wizard, configure the name and password of the Wi-FI connection;

Wi-Fi network name

  • 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, enter and save the settings that are indicated on the manufacturer’s website.

Also, for this router model, a simpler setup option is available by clicking Click’n’Connect in the main menu. However, it may not work correctly with some providers.

Restricting access on public routers

When you come to some coffee shops and connect your laptop to Wi-FI, you should not run programs to download torrents, since the network automatically turns off and is no longer restored even after rebooting the router, and access will re-open only after a day.

This limitation is set to ensure that visitors do not overload the already poor quality Internet access.

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

Since we do not have access to the coffee shop equipment, the only option left is to replace the mac address on our equipment.

Changing mac addresses Windows

On most equipment with operating system Microsoft Windows, the best option for changing the Mac address is to edit the registry. Despite the visual complexity, it does not require much time.

Creating a new registry setting

  • create a string parameter named NetworkAddress in this folder;
  • by double-clicking on it, add the value of the new mac address, represented by 12 hexadecimal digits (for example, “406186E53DE1”);
  • Restart Windows to apply the settings.

After this, the adapter will no longer be on the black list, and therefore you will be able to successfully connect to the Internet.
conclusions

There are many problems and solutions for them. Having found out which equipment malfunctioned, you can find the best way to fix the problem.

Considering the significant amount of material on the site on the topic “,” various types of problems that arise when a user encounters a wireless router are a frequent topic in the comments to the instructions. And one of the most common is that a smartphone, tablet or laptop sees the router, connects via Wi-Fi, but the network does not have access to the Internet. What's wrong, what to do, what could be the reason? I will try to answer these questions here.

Before we start, and assuming that literally half an hour ago everything was working, and now the connection is limited (if not, then this is not your case), try the simplest option - reboot the router (just unplug it and plug it back in), and also restart the device , which refuses to connect - very often this solves the problem.

Next, again, for those whose wireless network has recently worked and the previous method did not help - check whether the Internet works directly, via a cable (bypassing the router, via the provider's cable)? Problems on the ISP side are the most common reason“connections without Internet access,” at least in my province.

Which device is to blame for the fact that there is no access to the Internet - a router, laptop or computer?

First, if you have already checked the Internet by connecting the computer directly with a wire and everything works, but when connecting through a wireless router it does not, even after rebooting the router, then possible options usually two:

  • Incorrect wireless connection settings on your computer.
  • Problem with drivers for the Wi-Fi wireless module (a common situation with laptops that replaced standard Windows).
  • Something is wrong in the router (in its settings, or in something else)

If other devices, for example, a tablet connects to Wi-Fi and opens pages, then the problem needs to be looked for in a laptop or computer. Possible here too various options: if you have never used wireless Internet on this laptop, then:
