To reset TCP/IP in Windows NT (2000/XP/Seven) operating systems, there is special program netsh.exe.

netsh.exe- (Network Shell) allows configuration 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.*.*;

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. 😉

Reset the TCP/IP and Winsock protocol stack.

Signs:
a) I can’t connect to the Internet or local network, although everything is configured correctly.

b) The connection is established, but the connection status does not display: IP address, default gateway, etc.

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 may change malicious applications and viruses, as well as 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 They 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 - quite simple manipulation, which can even be handled inexperienced user. But before we get started, let us introduce the reader to two important nuances:

• Do not reset yourself at work or educational computer or otherwise corporate device, which does not personally belong to you. It is better to seek help from system administrator organizations. IN given cases a specialist manually sets certain settings TCP/IP protocol.
• It may be necessary after this manipulation re-tuning network settings of the computer to connect it to the Internet. For example, in some cases this is required by the provider.

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

Windows Vista: reset options

Reset network adapter here it is available in two variations. Let's look at them.

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. Type or copy from text next command: 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

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 that you turn to a reset. 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”.

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.

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, 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.
