Many users encounter a problem when the Internet and network stop working on their computer. Although the modem or router shows that the Internet is working. Therefore, Microsoft has added the ability to perform a self-service adapter reset in the Windows operating system.

This article will tell you how to reset Windows 10 network settings using updated system settings and how to reset network settings via the command line. In any of the cases, the netsh winsock reset command is used, which actually resets the network settings.

Before moving on to resetting network settings, you must first figure out whether it will help in a particular situation. The first symptoms of problems with the system’s network settings can be different, among them it is worth noting the most common:

  • File download speed is very slow.
  • After turning on the computer, literally within a few minutes the Internet disappears (although it works as expected for several minutes).
  • The computer does not automatically obtain an IP address.

All current situations are described in the case of full operation of the Internet from the provider. Resetting network settings is only needed if there is a problem with your operating system.

How to reset network settings in Windows 10

This action will remove and then reinstall all network adapters and return other network components to their original settings. You may then need to reinstall other network software (such as VPN client software or virtual switches).

After confirming the network settings reset, your computer will restart. When you turn on your computer for the first time after resetting the settings, the user will be asked to select the network on which your computer will be serviced.

Before it was possible to reset the adapter's network settings in the updated Windows 10 settings, resetting the network settings was done in a different way. The current method using the command line is also suitable for users of previous versions of the Windows operating system.


If the user receives messages, for example, the DNS server does not respond or the DNS server address cannot be found, then before executing the command netsh winsock reset You can try to reset the DNS cache. To do this you need to run the command ipconfig /flushdns in the command line running as administrator.

conclusions

A complete reset of the operating system's network settings is an excellent solution to many problems. Therefore, we looked at how to reset Windows 10 network settings using system settings or through the command line. If you need to reset network settings on previous operating systems, you can use the command netsh winsock reset, which actually helps to reset network parameters.

Are you having problems connecting to the Internet on your computer or smartphone? Often the situation can be simply resolved by resetting the network settings. We will tell you how to do this on popular platforms - versions of Windows and Android - later in the material.

Why do you need a reset?

Why, in fact, reset network settings? This manipulation is vital for situations when network settings are incorrectly changed, as a result of which accessing the Internet from a computer or smartphone becomes impossible. What is the reason? Settings can be changed by malicious applications and viruses, as well as by the user himself.

In this case, problems with IP or DNS appear. Consequence: the Internet is slow, some sites do not open at all, a connection to the router or provider cannot be established, and Wi-Fi cannot be distributed from the device.

Even experienced users believe that resetting network settings can in most cases cope with many Internet problems. The essence of the procedure is that it will reset the settings to factory settings, and also clear all parameters that were changed by the system, programs or the user himself.

Nuances of the procedure

Resetting network settings is a fairly simple manipulation that even an inexperienced user can handle. But before we get started, let us introduce the reader to two important nuances:

  • You should not perform a reset yourself on a work or school computer or other corporate device that does not personally belong to you. It is better to seek help from the organization’s system administrator. In this case, the specialist manually sets certain TCP/IP protocol settings.
  • It is possible that after this manipulation you will need to re-configure your computer’s network settings to connect it to the Internet. For example, in some cases this is required by the provider.

Now let's look at specific instructions for different versions of popular operating systems.

Windows Vista: reset options

Resetting the network adapter settings is available here in two variations. Let's look at them.

The first option is to use the special Microsoft Fix it utility. The program will help the user reset TCP/IP settings to factory settings. You can download it on the official Microsoft website. There is no need to perform any complicated actions: just run the utility on your computer, and the program will handle the problem itself. Once the task is completed, remember to restart your PC for the solutions to take effect.

The second option is to manually change the settings. Let's look at this procedure step by step:

  1. Click on the "Start" menu.
  2. In the search bar you need to enter the text cmd. Click on "Enter".
  3. "Command Prompt" will appear in front of you.
  4. Click on the inscription with the right mouse button.
  5. Select "Run as administrator" from the context menu list.
  6. Write (or copy from the article) the following into the line: netsh int ip reset logfile.txt.
  7. Execute the command (press "Enter"). As a result, the TCP/IP settings will be reset to factory settings, and the changes made will be written to the log file of the current directory from where it was launched.
  8. For the settings changes to take effect, all you have to do is restart your PC. That's all!

"Windows 7": via command line

First of all, let's look at resetting network settings using the command line. We begin the procedure as follows:

  1. Launch a command prompt on your computer as its administrator.
  2. The easiest way: go to the "Start" section, then enter cmd in the search bar.
  3. You will see "Command Prompt" in the results. Click on the inscription with the right mouse button.
  4. Select "Run as administrator" from the context menu.
  5. Run this command: netsh winsock reset. You can type it yourself or copy and paste from the text of this article.
  6. To execute the command, do not forget to press the "Enter" button.
  7. After the command is executed by the system, restart your computer.
  8. Check your internet access. As a rule, in most cases these simple steps are enough to completely solve the problem.

"Windows 7": if the command line didn't help...

However, sometimes resetting network settings via the command line does not work. What to do in this case? Go back to the command line:

  1. Repeat steps 1-4 from the previous instructions.
  2. Give your computer a new command: "netsh int ip reset c:\resetlog.txt". It can be reprinted or also copied from this text.
  3. Run the command and restart your computer. The problem should disappear after these steps.

Some experts advise, to be sure, to execute the commands from the previous and this subheading one after another, and then also reboot your device. As a result of these manipulations, the network settings on your computer will be reset to factory settings.

"Windows 7": DNS cache reset

You now know how to reset network settings on Windows 7 (manipulation, by the way, is also suitable for later versions of the OS) via the command line. However, you may encounter a similar, but slightly different problem: “The DNS server is not responding,” “The DNS server address cannot be found.”

What to do in this case? All you need to do is reset the DNS. In this case, we turn to the command line again:

  1. From the Start menu, go to the command line.
  2. Enter or copy the following command from the text: ipconfig /flushdns.
  3. Check your internet connection.
  4. If the problem is not solved, we recommend that you refer to the two previous instructions.

"Windows 7": using the Microsoft Easy Fix utility

Resetting Windows network settings is also possible through a special utility. You can download a program called Microsoft Easy Fix for free on the official Microsoft website.

How to use it? We offer an algorithm of simple actions:

  1. Launch the utility on your computer.
  2. Once the window opens, click on "Next".
  3. Then the program will independently introduce the necessary changes to the system’s network settings.
  4. When finished, the utility will prompt you to restart your computer.
  5. To do this, close the program and select reboot the system from the PC menu.

After this, the problem should disappear, and you will have access to the Internet on your computer again. And we will further analyze how to cope with it in the later tenth version.

"Windows 10": reset option

If you yourself have been “too clever” with the network settings or your device for no apparent reason stubbornly refuses to connect to the Internet, then we also suggest resetting it. On Windows 10 OS it is produced using a slightly different algorithm:

  1. Go to the settings menu. It can be found either through “Start” or by using the hotkey combination: Win + I.
  2. Go to the "Network and Internet" section.
  3. At this point you need a subsection called “Status”.
  4. Now scroll down to the very bottom of the page. There you will see what you need - “Network reset”.
  5. Click on the inscription. You will see a system warning: performing the action will remove and reinstall all existing network drivers, and also restore the factory (original, original) network settings. Note that you may have to reinstall your network software afterwards. For example, a VPN client.
  6. Click on "Reset Now". That's the whole procedure for resetting network settings in Windows 10.

As a result of these actions, the network settings will return to their original settings. The solution is quite drastic, so it is worth turning to it in cases where other methods of coping with the problem have proven powerless. Perhaps the situation can be saved by contacting a specialist.

Before resetting your settings, you should make sure that the problem is specific to your computer. Try connecting another device to the network. If there is also a lack of Internet access on it, then the problem is most likely with the provider or router.

Performing a reset on a smartphone

In conclusion, let's imagine resetting network settings on Android. Your smartphone may also experience problems with the Internet, which can only be solved in such a drastic way. We suggest you follow the instructions:

  1. Go to "Settings".
  2. Scroll through the menu and find the "Reset and Activation" item.
  3. Find the "Reset network settings" section.
  4. Here you just need to tap on the “Reset settings” button. In some smartphone models, the selected action must be confirmed.

If this manipulation does not help, then the solution is radical: completely reset the device to factory settings. But before that, you should copy important data from your smartphone.

Now you know how to reset network settings on various versions of Windows and phones on the Android platform. This solution allows you to cope with the situation when it is impossible to access the Internet from your device, when you accidentally changed the settings to incorrect ones. Available both through the settings menu, command line, and through a special utility.

Sometimes, it happens that the Internet connection settings go wrong or simply does not want to connect to the network (does not receive an IP address via DHCP). Similar problems can occur as a result of the operation of certain malicious programs (viruses). You can torture those for a long time. support from your provider or call a specialist at home. You can try to fix the problem yourself.
There is a special program to reset TCP/IP in Windows NT (2000/XP/Seven) operating systems netsh.exe.

netsh.exe— (Network Shell) allows you to configure network parameters.

Some nasty viruses get into WinSock and cause mischief.
Symptoms:

  • The speed of downloading files via TCP is very low (while downloading via UDP can be fast);
  • When you turn on the computer for a while, a couple of minutes, the Internet works fine, but then it disappears completely (the speed drops to 0);
  • The Internet works and the download speed is normal, but the downloaded file turns out to be broken because it is not downloaded completely (most likely the virus intercepts some of the packets during transmission, but sends a notification to the source that all packages have been successfully received).

In addition to viruses, you can also “break” your Internet connection yourself (or it “got wrong”)

Some examples:

  • The computer does not receive an IP address automatically (via DHCP);
  • IP addresses are pinged but not names;
  • The computer receives an IP address of the following type: 169.254.*.*;

If you have cleared yourself of viruses, you can begin recovery. ATTENTION! The following procedures will reset your network settings. I strongly recommend rewriting the settings.
To reset Winsock:

If the first command did not help solve the problem, you can reset the TCP/IP stack to factory settings:
There in the command line, enter the command:

netsh int ip reset c:\resetlog.txt

In this case, the reset log will be saved in the root of the C:\ drive; if you omit the c:\ prefix, the log will be saved in the current directory. After this, you should restart your computer.

After using this command, the following registry branches will be reset to factory settings:

SYSTEM\CurrentControlSet\Services\Tcpip\Parameters\
SYSTEM\CurrentControlSet\Services\DHCP\Parameters\

You can use these commands together one after the other. By the way, they also reset the DNS cache.
About DNS cache problems: For example, the site moved to another hosting, as a result its IP address changed. And since you have some not quite fresh data in your cache, when you enter the site name, you will be taken to the old IP address, where the site no longer exists.

To avoid resetting all settings, try the command ipconfig /flushdns If it doesn't help, use netsh int ip reset resetlog.txt- this is guaranteed to help and reset everything related to network connections. 😉

Sometimes you need to reset the adapter. To carry out this task, you must enter the network connections section. This is done in the following order: you need to go to the control panel from the Start menu. Using the search system, find the adapter, then in the section for managing sharing and networks, select “Show network connections.” Right-click on the adapter icon and select “Disable” before resetting the wireless network settings. If you are required to enter or confirm an administrator password, you must provide the password or confirm.

By right-clicking on the network adapter icon, select the enable command. If you are prompted for an administrator password or need confirmation, you must enter the password (confirm). The network adapter is now returned to its default settings. You can read about how to connect the DVR to the network in the corresponding section of this site. Now that the settings have been changed, you should try connecting to the network again. You can also use a network troubleshooter to verify that the adapter is working correctly.

The sequence of actions is as follows: you need to open the troubleshooter. To do this, right-click the mouse to select the network icon located in the notifications and click the troubleshooting command. Information on how to send a message over the Internet and other useful tips are available to visitors to this site. If, after performing the steps to reset the network adapter, as well as updating the drivers, the network troubleshooter still indicates that there are problems with the adapter, you still need to replace the adapter.

You can purchase a network adapter in specialized stores. Its installation is easy. On special websites you can find information on how to install the adapter, how to set up a VPN network and much more. The device also comes with instructions with which you can install the network adapter yourself. If problems arise, you should seek the help of a specialist. If you decide that the adapter should not be used, then you must either remove it from the system or simply turn it off. Many users are interested in how to log into social networks. By clicking on the link or using the search system, you can get the necessary information.

When you disconnect the adapter, it will become inactive, i.e., it will not be used. The sequence of actions is as follows: from the “Network Connections” component (opens by clicking on “Start” and going to the section for managing networks and sharing), through the search system you need to find the adapter (type “adapter” in the search window) and click on the “Show” item Network Connections" in the Network Control Center. All that remains is to click on the “disable” command. If a password or confirmation is required, you must enter the password (confirmation).
