The Internet is connected, but does not work. Installing a discrete network card. Ways to solve problems connecting to a Wi-Fi network (Internet)

In this article we will try to figure out why and why the browser stops loading pages and accessing different sites. Despite the fact that the Internet continues to work normally, judging by the connection status on the notification panel. In this case, it doesn’t matter at all whether you have a PC or a laptop. It has Windows 10, Windows 8, or Windows 7 installed on it. And it doesn’t even matter how you connect to the Internet: via cable directly, or via a Wi-Fi router.

If there is some kind of red cross or yellow exclamation mark next to the icon, then the browser does not load the pages due to lack of Internet connection. And this problem needs to be solved. First of all, reboot the computer and router (if you have a connection through it). You may also find these articles useful:

When the Internet connected and working, then the icon should be like this:

Usually, when there is Internet but sites do not load, then programs such as Skype do not lose the Internet connection. Pay attention to this. And if your Internet works (connection status as in the screenshot above), but does not access sites through different browsers, then try using the recommendations that I will write about later in this article. And further:

• If you are connected through a router, check whether the sites load on other devices. If not, then reboot your router. You can also connect the Internet directly to your computer and try to access a website. Perhaps this problem was caused by the provider.
• If the problem is only on one computer, then it is important to remember when and after what it appeared. For example, after installing some program.
• Restart your computer and run Windows Network Diagnostics. You need to right-click on the connection icon and select “Diagnostics problems”. You can write about the results in the comments.
• Try visiting different pages. Perhaps the problem is in one specific site. Also try different browsers.

The problem is clear, let's move on to solutions.

If the browser does not load pages, the first step is to change the DNS

This is the most popular and most working solution to this problem. Almost always, it is because of problems with DNS that sites do not load when the Internet is working. And in such cases, I recommend registering DNS from Google. This is not at all difficult to do.

You need to go to network connections. Do it in a way that is convenient for you. You can press a keyboard shortcut Win+R, enter the command ncpa.cpl and click Ok.

Right-click on the connection through which you are connected to the Internet and select "Properties".

In the new window, highlight “IP version 4 (TCP/IPv4)” and click on the “Properties” button.

As in the screenshot below.

Everything should work right away. If not, then try restarting your computer.

More information on this topic in the article:.

ipconfig/flushdns – flush DNS cache

Start a command prompt as an administrator and run the command ipconfig/flushdns. The DNS cache will be reset and the problem may be resolved.

It should look something like this:

After this, it is advisable to reboot.

How proxy settings can affect how pages load in your browser

If there is some program, perhaps even malicious, or we ourselves change the proxy server settings, then this may cause this problem. You need to check that there are no unnecessary settings in the proxy server settings.

In Control Panel, find and open "Educator Properties". If you have Windows 10 installed, this item will be called “Browser Options”. You can type this phrase in the search, it will be faster.

On the "Connections" tab, click on the "Network Settings" button. Check that the settings are like mine in the screenshot below.

If everything is fine there, then move on to the next solution.

Resetting network settings

In Windows 7, Windows 8 (and even in Windows 10), you can reset network settings using separate commands, which must be executed one by one in the command line running as administrator.

ipconfig /flushdns

ipconfig /registerdns

ipconfig /release

We execute the commands one by one.

Don't forget to restart your computer.

Avast installed?

If Avast antivirus is installed on your computer, then there is a high probability that the browser cannot load sites precisely because of it. There are reviews in the comments that reinstalling the antivirus solves this problem.

Try uninstalling Avast first. If the Internet works, you can install it back.

Nothing helped, are there any other options?

Check your computer for viruses. There are many good, free antivirus utilities. If you have an antivirus installed, then run a computer scan.

You can also try temporarily disabling your antivirus. Maybe he changed some network settings, and the pages in the browser stopped opening.

Think, maybe the problem appeared after installing or uninstalling some program. Or change some parameters. This way you can find out at least an approximate cause of these problems.

If I remember anything else, or learn something new about this problem, I will definitely update the article. You also share your experience in the comments, write about working solutions. You can leave your questions.

Internet is connected but not working

The title of the post is strange, but it looks exactly like this:

• The computer is connected to the router, but the Internet does not work on the computer;
• When the cable is connected to the network card, the connection indicators on the board do not light up;
• The Internet is guaranteed to work. If you connect another computer or laptop to the same cable, you can access the Internet without any problems.

Such symptoms indicate that the integrated network card in the computer has failed.

Let's look at the problem and its solution using a specific example. We connect the network cable to the computer, but the Internet does not work, the computer does not signal in any way that the cable is connected. Let's see if the computer “sees” the network card (network card, network adapter, “network card”). To do this, you need to look at the list of devices in Device Manager.

Step 1. Go to the main menu by clicking on the Start button > then right-clicking on Computer > in the context menu select Properties.

Step 2. In the window Properties of the system go to the Hardware tab and click on the button device Manager.

Launch the device manager

Device Manager has launched. As expected, the network card is not listed.

To make sure once again that the problem is in the hardware and not in the software, the operating system was loaded on the computer from a CD-ROM. After booting Ubuntu, the network cards were also not detected.

Conclusion: The integrated network card has failed. The elements of the integrated network card are located on the motherboard, i.e. the integrated network card cannot be replaced without changing the motherboard. However, we can install a discrete (external) network card.

Installing a discrete network card

After you open the system unit, it is advisable to clean it of dust (). After this, you can safely begin installing the network card.

I didn’t have to choose a network card; the owner of the computer bought it himself. The choice fell on the D-Link DFE-520TX. Network card contents:

• Network card;
• Driver disk;
• Instructions.

The network card can be installed in any free PCI slot. Budget motherboards may only have one PCI slot. In this particular case, there are three slots and the network card will be installed in the top PCI slot.

The network card will be installed in the top PCI slot

Step 1.

Step 2.

Step 3. We fix the bracket with a screw. If you don't have spare screws, you can borrow one screw from the case cover or from the power supply.

Close the system unit case, connect all the necessary cables and turn on the computer's power.

Installing network card drivers

If the computer is running the Windows 7 operating system, the drivers will be installed automatically. In this particular case, the Windows XP operating system was installed on the computer, so installing drivers was required.

This post originally appeared . Let me explain that an Ethernet controller is a network card.

Network card detected

The Found New Hardware Wizard starts automatically. By default, the installation option is offered "Automatic installation (recommended)"— we leave this option.

Leave the option “Automatic installation (recommended)”

Insert the driver disk into the CD drive. After this, the driver installation will begin. If it does not start automatically, click on the Next button.

The Found New Hardware Wizard easily detected the installed network card. At this step, simply click the Next button.

We don't change anything. Just click the “Next” button

During the process of installing network card drivers, you do not need to do anything.

After installing the drivers, all that remains is to click on the Finish button.

The master has completed his work. All you have to do is click on the “Done” button

If the driver installation process proceeds without failure, a message should appear .

Network card drivers installed successfully

If we now look at Device Manager, we will see that the network card has appeared in the list.

Discrete network card appears in the list of devices

The Internet works, i.e. mission accomplished. If you look at the network card, you will see that the green indicator is blinking, which indicates that data is being transferred.

That's all. If you have questions, comments, suggestions, leave them in the comments.

It's a scary moment when your computer connects to Wi-Fi, but the Internet doesn't work. Unfortunately, there is no single solution to this problem, since the error may be related to the operating system settings or the router.

We've put together a step-by-step guide to help you fix the problem.

Where to look?

If you are facing the "no internet access" problem, then you need to look at:

• Router
• The device that is experiencing the problem

If the Internet does not work on all devices connected to the Wi-Fi network, then most likely there is a problem with your router/modem. You can also look at the Ethernet cable to make sure it is not broken or twisted.

If the Internet does not work only on the computer, while other devices connect perfectly to the wireless Wi-Fi network, then the problem is with the Wi-Fi adapter on the computer or again with the router that cannot connect to the computer.

To fix the “no internet access” problem, you can follow these nine steps. So, let's begin.

1. Restart your computer and router

Yes, I know it sounds stupid, but most problems are solved with a simple reboot.

A good reboot is the solution to many software and network connection problems. Turn off your router and wait 30 seconds before turning it back on. Additionally, you should restart your computer to ensure that it is also working properly. Once all devices have rebooted, try connecting again.

2. Check the signal indicators on the router

It's possible that the problem is with your Internet connection and not with your computer. To confirm, you need to check the indicator on the router and make sure it is lit.

Ideally, the lights on the router should be green and the Wi-FI indicator should be blinking. If you are unsure, contact your ISP customer support.

3. Use the built-in troubleshooting tool

If the ISP claims that the Internet is working properly, then there is most likely a problem with the WiFi adapter on your device. This can be easily fixed using the built-in troubleshooter that is available by default on Windows.

The built-in network troubleshooter on Windows can resolve, or at least report, most network problems. Right-click the network icon on the taskbar and select " Troubleshooting" Windows will begin searching for the problem and how to fix it. If the system cannot fix them, it will let you know what the problem is. After that, you can find a solution on the Internet, or ask in the comments below, we will try to help you.

4. Clear DNS

Sometimes an error in the DNS cache can cause problems accessing websites and you may think that the Internet is down. In this case, you need to clear the DNS.

Click on menu " Start" and enter " cmd" Next, open a command prompt as an administrator.

A command prompt window will open where you have to type “ ipconfig/flushdns» and press the enter key ( Enter). This command will clear the DNS cache.

5. Change the wireless mode on your router

If your computer can access the Internet when you connect the Ethernet cable directly, while the Internet does not work via Wi-Fi, then the problem may be with the wireless mode.

Routers support multiple wireless modes. For example, you may have encountered symbols such as 802.11b or 802.11 b/g or 802.11 b/g/n etc. So, b, g, n and ac are different wireless communication standards. B is the oldest WiFi standard that covers a smaller area and provides lower data transfer speeds, while AC is the latest WiFi standard with wider coverage and 1Gbps network speed.

Generally, most people use wireless mode 802.11 b/g/n/. But sometimes old devices (especially old smartphones) do not work with this mode, so they connect to Wi-Fi, but there is no Internet.

One way to fix this problem is to log into the router's control panel through a computer, then find the section Wireless mode. Usually it is in settings wireless network (Wireless), where you set the name and password for the Wi-FI network. Next to Wireless Mode you will see a drop down menu, click on it, select 802.11b and save the changes. Now restart Wi-Fi on the devices that were unable to connect to the Internet and check if the problem has been resolved. If the Internet still doesn't work, try 802.11g wireless mode. If you are still unlucky, then look further for a solution to your problem.

6. Automatically obtain IP and DNS

If your smartphone or computer connects to another Wi-Fi network but does not work with your wireless network, there is a possibility of a DNS or IP address conflict. You can check this by ping your router via cmd prompt. If you get a time out response, then there is most likely an IP address conflict.

Ideally, you should configure your network settings to automatically obtain the IP address and DNS provided by your ISP. This ensures the least amount of conflicts. However, sometimes assigning a static IP address or changing the DNS server can help resolve Internet access problems. Conversely, if you are using a static IP address, then it would be wise to obtain an IP address automatically. In short, try changing the settings and see if you can fix the problem with Internet access.

To obtain an IP address automatically in Windows, press the keys Windows + R and enter " ncpa.cpl" in the Run dialog box that opens. When you press " OK", all your network connections will open. Right click on your network and select " Properties» in the context menu.

Now select " IPversion 4", and press " Properties"underneath it. In the next dialog box, select the option: " Obtain an IP address automatically" And " Obtain DNS server address automatically" Restart your computer and check your Internet access.

7. Problems with the network driver

Sometimes the problem with accessing the Internet is an old network driver. To update the network driver on your computer, press the keys Window+R and enter " devmgmt.msc" You will open the window " device Manager».

In the menu on the left, expand the section " Network adapters" and right-click on your network. Now select the option " Update drivers", and you will get two options to update the driver: manually and automatically (online).

Try connecting your computer to your router using an Ethernet cable to access the Internet. If the connection is established, click " Automatically search for updated drivers", and Windows will automatically find and install the required driver.

In case you are unable to connect to the Internet via an Ethernet cable, you will have to manually download the latest driver from the manufacturer's website from another device and then transfer it to a computer without Internet access. Next, select the option “ Search for drivers on your computer" to manually install the latest drivers.

8. Reset the router to factory settings

This is a pretty tough option, but in most cases it solves all problems associated with the router. You can reset your router to factory settings. This allows you to fix the problem with Internet access. This also means that you will have to re-set the basic settings, password and other network settings.

You can reset the router to factory settings by pressing the reset button on the router itself. Usually the reset button is hidden inside a tiny hole, so you'll need a ballpoint pen or toothpick. Press the button and hold it for 5-15 seconds until all indicators start flashing.

9. Call your Internet Service Provider

If none of the methods solved your Internet access problem, then you should let your Internet service provider do it. They will conduct a consultation over the phone, and if necessary, they will send a specialist to your home.

Summarizing

As I said before, there is no one way to solve the Internet access problem. The above tips should help you fix most software related issues. However, if the problem with accessing the Internet is related to the computer hardware - for example, the network card or router is broken - then you will have to turn to experienced specialists.

Let's look at a problematic situation when the phone connects to Wi-Fi, but there is no Internet. It looks like this: next to the name of the wireless network it says “Connected”, but when you try to open any site in the browser an error is displayed Web-page is unavailable or 404 Not found. Chrome still writes in such cases. The same applies to other software - all kinds of programs that use the Internet connection for their work or at least check for updates when starting will also display an error connecting to their web server.

In this article, we will talk in detail about how to solve the Internet problem on your computer, phone or tablet. Read carefully, follow all the steps and you will definitely find the reason why you do not have an Internet connection when your Wi-Fi connection is working.

Collecting information about the problem

Before making any changes to the Wi-Fi settings of your router, computer, or phone, check the following points. This may make it easier to find the reason for the lack of Internet or narrow down your search:

• Is the Internet paid for and are the funds in the account running out?
• Is there access to the Internet via wire from a desktop computer?
• Is it possible to access the Internet via Wi-Fi from other devices that use the same Wi-Fi router?
• does the Internet connection problem persist when connected to another Wi-Fi network?

Depending on the answers to these questions, it may already become more or less clear to you what the problem most likely is. Eg:

• if there is no Internet at all - neither via wires nor via Wi-Fi, then the reason may be either access blocking on the provider’s side or a malfunction of the router. Next, we check with the provider whether everything is in order with the line and the account, and then we check the functionality of the router.
• if the Internet is available on the PC via wire, but not on any device via Wi-Fi, then the problem most likely lies in the wireless network settings of the router. The same conclusion can be drawn if the Internet appears and works without problems as soon as you connect to another Wi-Fi network from the same device
• and if it turns out that all devices are in order, and only one does not have an Internet connection, then the problem is obviously in this “client”.

Wi-Fi is connected, but the Internet does not work. What to do?

So, if your Wi-Fi is truly “connected”, but there is no Internet (websites do not load, Skype and Viber do not connect, a yellow network icon is displayed on the laptop with the notification “No Internet access”), follow these steps to resolve the problem. The steps are listed taking into account the probability factor.

1. Reboot your router

Sometimes the inexplicable happens router failure . At the same time, the local network and Wi-Fi work normally, but there is no access to the Internet. This can happen when the router operates for a very long time without reboots and when there are changes in the provider’s network. Just in case: it is written how to reboot D-Link remotely.

2. Reboot the device where there is no Internet connection (phone, laptop)

Sometimes on a smartphone (tablet, laptop) a certain failure (glitch), which can cause a similar problem. Visually, everything seems to be fine, but there is no Internet for no apparent reason. To eliminate such a failure, reboot the device.

3. Reconnect to the Wi-Fi network

This step is very important, despite its simplicity and obviousness at first glance. You need to forget the Wi-Fi network, and then connect to it again by entering the password (security key). This may resolve the issue and restore your internet connection, for example if network settings have been changed user or virus.

4. Set the correct date on your Android device

Invalid date may be causing an internet problem. In this case, the sites will open, but Antiviruses, Google Play Market, etc. may not work. .

5. Disable the proxy server

If a proxy server is enabled on your computer or Android device, you may also experience a situation where Wi-Fi is connected but there is no Internet. This problem usually occurs on Android.

6. Check the Internet connection settings on the router

Go to the WAN or Internet settings on the router. (). Check that you have specified correct connection parameters , such as:

• type of connection with the provider (look in the contract or on the provider’s website);
• login and password, if required (see the contract);
• is the MAC address specified correctly (check in the contract. If you reset the router, you may have to go to the Internet provider’s office with your passport and contract and ask to register a new MAC address for the router’s WAN port).

If your provider uses a PPTP connection, and the settings on your router have gone wrong and now IPoE (dynamic IP) is selected instead of PPTP, then naturally the router will not be able to connect to the Internet. In this case, the sites will not open on any device.

7. Change the wireless channel

Wireless equipment that is located nearby and operates on adjacent channels can create interference to your router. Try changing the Wi-Fi channel.

It would be even better to first check which channels are freer. This can be done using the Android app or InSSIDer for Windows.

8. Install WPA2-PSK + AES encryption for your Wi-Fi network

The WPA2-PSK encryption algorithm is the most secure. And AES encryption provides high speed and security. Most devices, even not new ones, work successfully in WPA2-PSK mode with the AES algorithm.

Wi-Fi is connected, but the Internet does not work: other causes of the problem

If the distance from the client device to the router is too great, the following problem may also occur: the device has received an IP address, but there is no Internet. Therefore, you first need to check whether the Internet appears when approaching the router (if it is possible to get close). Then - if the problem is the distance - somehow try to reduce it. If the router is yours, place it in the middle of the house.

Some organizations provide free Wi-Fi, but in order to be allowed on the Internet, you need to launch a browser, enter a password, or go through some other authorization procedure. For example, indicate a phone number and enter a code from an SMS. It is better not to contact such networks and not to enter any information about yourself in order to avoid problems. It is much easier to find another access point without such nuances.

If you've done everything and you still can't connect to the Internet through an active Wi-Fi connection, there's another option: set up a static IP address. This method is not a solution in the full sense of the word, but in some cases it helps to bypass the problem and gain access to the Internet. To do this, on your smartphone, call up the properties of the connection to the Wi-Fi network, check the box Show advanced options and select Static IP:

I hope this guide helped you identify and fix your Internet connection problem and now all your devices are connected to the network, both wired and wireless. Please write questions and additions to the article in the comments.
