After reinstalling windows no. The Internet does not work after reinstalling Windows. Setting up the Internet on Windows

Often after reinstallation operating system Users are faced with a situation where the Internet does not work on their computer. Let's find out how to fix the indicated problem on a Windows 7 PC.

The reason for this problem is quite trivial: after reinstalling the system, all settings are lost, including Internet settings, and the network drivers. The algorithm for getting out of this unpleasant situation depends on the specific method of connecting to the World Wide Web. Below we will look at the procedure for troubleshooting this problem when using Wi-Fi and standard cable connection via connector network card 8P8C.

Method 1: Wi-Fi

First, let's look at the algorithm of actions when using a Wi-Fi connection. The main reason for failure to exit in world wide web After reinstalling the OS, there is a lack of a corresponding driver for the adapter through which communication via Wi-Fi occurs.

Click "Start" and go to "Control Panel".

Next, go to the section "System and Security".

In the window that opens in the block "System" find the subsection "Device Manager" and click on it.

The interface will open "Device Manager". Click on the section name « Network adapters» .

If in the list that opens you do not find the network adapter with which you connect to Wi-Fi at all, or if there is an exclamation mark next to its name, this means that required driver missing or incorrectly installed.

Try reinstalling it. To do this, select top panel "Action" and click on the item "Update configuration...".

After this, the configuration update procedure will be performed and there is a possibility that your network adapter will be displayed, and, therefore, the Internet will work.

But an outcome is also possible in which everything remains as before. In this case, only installing the “native” drivers of this device will help you. They can be installed from the disk that came with the adapter. If for some reason you do not have such a medium, then necessary component can be downloaded from the manufacturer's official website. After installing the driver and displaying the device in "Dispatcher", perform a search available networks and connect to the one you have access to by entering the password as you would normally do.

Method 2: Internet via cable

If you have regular cable Internet, then even in this case, after reinstalling the operating system, there may not be a connection to the World Wide Web. The likelihood of this is even higher than in the previous case, since interaction with many providers requires special settings, which naturally got lost during the OS reinstallation process.

Left-click on the network connections shortcut in the notification area. In the list that appears, go to "Control Center...".

In the window that opens, navigate by position “Setting up a new connection...”.

Then select "Internet Connection" and press "Next".

Choose one of two connection options provided by the provider:
- High speed;
- Switched.
With a high degree of probability, you will need to choose the first option, since a dial-up connection, due to its low speed, is currently quite rarely used.

A window will open for you to enter information about your service provider. To connect to your provider, enter your username and password into the appropriate fields, which the service provider must give you in advance. In the field "Connection name" you can enter an arbitrary name by which you will recognize the connection being created among other objects on the computer. If you do not want to repeat the authorization procedure every time you log into the network, then in this case, check the checkbox "Remember this password". After all the above settings have been entered, click "Connect".

After this, the procedure for connecting to the Internet will be carried out.

But there are times when you have entered all the settings correctly, but you still cannot connect to the World Wide Web. In such a situation, open "Device Manager" in section "Network devices", as in the situation with Wi-Fi. This time, a signal of trouble should be the absence of a computer’s built-in network card in the list. Next, do all the manipulations, including updating the configuration and, if necessary, installing drivers that have already been described above.

After this, the built-in network card should appear in the list, and the Internet should work.
But this does not always help, and if after performing these steps the problem does not disappear, you need to check the network settings. This is relevant if your provider does not support working with automatic settings. But first you need to contact your service provider to find out exactly what data needs to be entered. In particular, the IP address and DNS server address. Next, go to "Control Panel" and choose "Network and Internet".

Then open the next section "Control Center...".

After that, move on to the position "Changing parameters...".

In the window that opens, find the name of the connection through which you want to activate communication with world wide web. Right-click on it and select a position "Properties".

In the displayed shell, in the list of components, find the name "Internet Protocol (TCP/IP4)". Select it and click "Properties".

It is in the window that opens that you should enter the settings provided by the provider. But in order to be able to enter data, move the radio buttons to the position "Use…". After that, enter information in the active fields and click "OK".

The network connection should appear.

After reinstalling the operating system, the Internet may disappear due to the lack of necessary drivers or loss of installed settings. The algorithm of actions to resolve this problem depends on the type of connection to the World Wide Web.

On the computer, after each reinstallation of OS Windows 7, you have to reinstall all programs, drivers and connect peripherals. But in the age unlimited internet, a person cannot imagine his existence without it. Therefore, the problem of connecting to the global network after reinstalling the operating system always remains relevant.

Connecting to the Internet via routers

Owners of routers (routers) are luckier, since all settings are stored directly on separate device, so reinstallation is not scary, and you just need to make sure correct setting network between PC and router. On Windows 7, you can check this in the Network Sharing Center and shared access (Start - Control Panel - Network and Internet - Network and Sharing Center). Next, in the left menu, follow the link “Change adapter settings”

and check that the “connection via local network", for the main network adapter:

You can check the name of the main network card in Device Manager. The easiest way to find it is to hold down the WIN+Pause key combination (the combination is supported in all versions of the OS, including Windows 7, Windows 8 and Windows 8.1).

and in the device tree you need to find the “Network adapters” sub-item. Here a list of all network cards (including virtual ones) installed in the computer will appear.

Another question is when there is not a single network card here, but there are unknown devices - install drivers for your network equipment.

If this does not help, check that you are setting the appropriate software. In the worst case, the network card does not work and needs to be replaced.

When network connection will be established with the router - the Internet connection will be activated automatically.

Direct Internet connection using Windows 7 as an example

If you do not look at the fact that now most providers provide Internet services without using a login and password (binding by MAC address and you just need to insert the cable into the PC), let's take a closer look at how to set up and connect your computer to the Internet using a login and password (PPPoE protocol).

First you need to check how the network card works (checking the network connection). Next, go to: “Start - Control Panel - Network and Sharing Center.”

Here we select the item according to the picture:

In the next step, select “High-speed (with PPPoE)”:

After selecting the connection type, a window will appear with fields that need to be filled in accordingly and click the “Connect” button:

After filling in all the fields, the computer will attempt to connect using the previously entered data:

If no mistakes were made at the setup stage, you will be able to connect your Windows 7 computer to the global network right away. If, after all the steps, the Internet does not work, you need to delete the created connection and repeat the process again.

Another way to set up a direct connection on Windows 7

Some providers work using another parameter called “Service Name” to distribute the load between servers. It improves connection stability, but adds hassle to ordinary users.

If you have after reinstalling Windows the Internet does not work, then in most cases there can be 2 reasons:

When reinstalling, the drivers were removed (most often).
Providers themselves block the Internet, thinking that it is unauthorized access to the network from another computer under your login.

In the second case, you need to contact the provider by phone, and technical support will solve everything in 1 minute. In the first case, you need to read our article.

The reasons for missing drivers may be the following:

The disk was formatted, a new OS was installed, and drivers for your hardware are not included in the standard Windows set.
Has been installed Windows assembly, in which someone specifically disabled what he thought were “unnecessary” standard drivers.

Eliminate hardware problems

After re Windows installations Internet not working? First, check the hardware, look at the network card on the back system unit:
The network card indicators are on, everything is OK.

If the light is on, it means everything is OK with the hardware.
If it is not lit, the network card is not working or the cable is damaged.

How to check Wi-Fi wireless hardware:

Make sure that the communication module is active: the Wi-Fi LED on the laptop keyboard or the network indicator in the tray (for Windows watches).
The operation of the 3G modem is also determined by a flashing LED.

The simplest solution

Use the driver disk. You should still have it after purchasing a PC, most often it is a disk from motherboard, which has a built-in network. Just install drivers for your network card or Wi-Fi software.
Search for drivers on the Internet from another computer. 1) if it’s a laptop, then enter its name into the search, for example, “ Lenovo laptop M3070 driver"; 2) if it’s a desktop PC, enter the name of the motherboard into the search and look for drivers for the network card.

From the Internet it is better to download the diver and other system software from the manufacturers’ websites, it is sure to be there.

How to set up Internet on Windows 7

Before setting up the Internet, it is advisable to make sure that all drivers are installed on network devices(modem, network card). If you don’t understand this and don’t want to bother yourself, then you can try it right away, maybe it will work. A method for those who do not have a router (connect directly via cable from the provider).

Go to the control panel.

Select Category view.

Next, “Network and Sharing Center.”

Then the link “Set up a new connection or network.”

Options for connecting to the Internet appear. If you have an ADSL connection, then select the first item: “Internet Connection”. In the case of 3G, “Setting up a telephone connection.” Most often, the first option, we will consider it further.

Another window appears, click on “High-speed (with PPPoE)”. When setting up 3G, there will be a modem selection here.

Enter your Internet login and password. There will be an additional feature for 3G users. “Dial number” field. After entering the data, click “Connect”.

If all drivers are installed, the devices are working and the login is correct, then “The Internet connection is ready for use” will appear.

After this, you can create a shortcut on your desktop to connect to the Internet. In Control Panel, find “Network and Sharing Center”, then “Change adapter settings”. Right-click on the newly created connection, select “Create shortcut”.

For router owners

Those who have Internet access through a router do not need to configure anything. Most often, immediately after reinstalling the OS, the Internet connects itself, because all the settings are stored in the router itself. If there is no network, your task is to find drivers for the network. cards or Wi-Fi.

If you have a USB modem

The USB modem is connected to the computer in hot mode. This means that you turn on the computer, wait full load OS, and only then insert the USB modem.
Wait a little. The operating system notification about new hardware should appear.
After this, a window will pop up with the opportunity to install a program for working with a USB modem.

Usually operators mobile internet provide a service with auto-configuration and dynamic IP. You don't need to do anything, but there are times when you need to manually configure the connection. Then refer to the documentation, and if it is not there, then contact technical support provider.

Preparing to reinstall Windows

Video on how to use the program:

In addition, we recommend checking in advance that you have driver disks on hand. Also read, namely the section about saving data. You'll learn how to save a list of programs used on your old OS so you can easily find exactly what you need.

Good day.

When installing new Windows, as a rule, the system automatically configures many parameters (will put universal drivers, will set the optimal firewall configuration, etc.).

But it just so happens that some things are not automatically configured when reinstalling Windows. And many who reinstalled the OS for the first time are faced with one unpleasant thing - the Internet not working.

In this article I want to look at the main reasons why this happens and what to do about it. (especially since there are always a lot of questions regarding this topic)...

The most common reason why there is no Internet (note after installing a new Windows OS)- this is the absence of a network card driver in the system. Those. the reason is that the network card simply doesn't work...

In this case, a vicious circle results: There is no internet, because... there is no driver, and the driver cannot be downloaded - because... no internet! If you don’t have a phone with Internet access (or another PC), then most likely you won’t be able to do without the help of a good neighbor (friend)...

Usually, if the problem is related to the driver, then you will see something like the following picture: a red cross will light up above the network icon, and an inscription something similar to this: "Not connected: no connections available"...

In the control center - on the right there will be a tab "Changing adapter settings" - this is what you need to open.

IN network connections you will see your adapters with drivers installed. As you can see in the screenshot below, my laptop does not have a driver for Wi-Fi adapter A (there is only an Ethernet adapter, and even that is disabled).

By the way, check, it’s possible that you have the driver installed, but the adapter itself is simply turned off (as in the screenshot below - it will just be gray and it will say “Disabled”). In this case, simply enable it by right-clicking on it and selecting the appropriate menu in the context menu that pops up.

Network connections

I also recommend looking into the device manager: there you can see in detail which equipment has drivers and which do not. Also, if there is a problem with the driver (for example, it does not work correctly), then the device manager marks such equipment with yellow exclamation marks...

To open it, do the following:

Windows 7 - in the Run line (in the START menu), paste devmgmt.msc and press ENTER.
Windows 8, 10 - press the WIN+R button combination, paste devmgmt.msc and press ENTER (screenshot below).

In Device Manager, open the Network Adapters tab. If your equipment is not in the list, it means the drivers are in Windows system- no, which means that the equipment will not work...

How to solve the driver issue?

Option #1 - try updating the hardware configuration (in device manager: just right-click on the network adapters header and select the desired option. Screenshot below).
Option No. 2 - if the previous option did not help, you can use special utility 3DP Net (It weighs about 30-50 MB, which means it can be downloaded even using your phone. Moreover, it works without an Internet connection);
Option number 3 - download on the computer of a comrade, neighbor, friend, etc. special driver package - ISO image by ~10-14 GB, and then run it on your PC. There are a lot of such packages floating around the Internet, I personally recommend Driver Pack Solutions ;
Option No. 4 - if none of the previous ones worked and did not give results, I recommend looking for the driver by VID and PID.

And this is what the tab will look like when the driver for the Wi-Fi adapter is found (screen below).

If you can't connect to the network after updating the driver...

In my case, for example, Windows refused to search for available networks and after installing and updating the drivers, it still showed an error and an icon with a red cross.

Next, the troubleshooter will automatically begin to fix problems related to network inaccessibility and advise you on each step. After the button has been pressed "Show list of available networks"- the troubleshooting wizard configured the network accordingly and that’s it available Wi-Fi networks became visible.

Actually, I stayed finishing touch- select your network (or the network for which you have a password to access) and connect to it. That's what was done...

Entering data to connect to the network... (clickable)

2. Network adapter is disconnected / Network cable is not connected

One more common cause lack of Internet is a disabled network adapter (if installed driver). To check this, you need to open the network connections tab (where all network adapters that are installed in the PC and for which there are drivers in the OS will be shown).

The easiest way to open network connections is to press the WIN+R buttons together and enter ncpa.cpl (then press ENTER. In Windows 7, the run line is located in START"e).

Opening the Network Connections tab in Windows 10

In the network connections tab that opens - pay attention to the adapters that are displayed gray (i.e. colorless). Next to them there will also be an inscription: “Disabled”.

Important! If there is nothing at all in the list of adapters (or there is no adapter that you are looking for) - most likely you simply do not have it in your system the required driver(the first part of this article is devoted to this).

To enable such an adapter, simply right-click on it and context menu select "Enable" (screenshot below).

After the adapter is turned on, pay attention to whether there are any red crosses on it. As a rule, the reason will even be indicated next to the cross, for example, in the screenshot below “The network cable is not connected.”

If you have similar error- you need to check the network cable: perhaps it was chewed by pets, hit by furniture when it was moved, the connector was poorly crimped, etc.

3. Incorrect settings: IP, default gateway, DNS, etc.

Some Internet providers require you to manually set certain settings TCP/IP (this applies to those who do not have a router into which these settings have been entered once, and then you can reinstall Windows at least 100 times).

You can find out whether this is so in the documents that your Internet provider gave you when concluding the contract. Usually, they always indicate all the settings for Internet access (as a last resort, you can call and check with support).

Everything is set up quite simply. In network connections (how to access this tab is described above, in the previous step of the article), select your adapter and go to its properties.

Ethernet Network Adapter Properties

The problem when the Internet does not work after reinstalling Windows can arise not only in Windows 7, but also in Windows 8 and Windows 10. I will later try to prepare a separate article about solving this problem on the “top ten”. Besides, I already wrote. Just follow a few tips from the article, and the Internet on your computer will work again.

And in this article, we will look at solutions to the problem when you (or someone else) installed on your computer, or Windows laptop 7, everything worked out and everything works, but there is no Internet connection. There could be a lot different nuances. Because there are many ways to connect to the internet. Therefore, the solutions will also be different. Looking ahead, I will say that most likely you will just need to install the necessary drivers, or set up an Internet connection (or both). Because, immediately after installation, Windows 7 almost never installs a driver for the Wi-Fi adapter. This means that Wi-Fi will not work after installing Windows 7. Well, if you had an Internet connection configured, then of course you need to configure it again.

It all depends on the connection method, and in some cases on the Internet provider. We will consider the following options:

Wi-Fi does not work after installing Windows. In almost all cases, simply installing the wireless adapter driver is enough. Windows 10 already installs the driver for Wi-Fi (in most cases), but Windows 7 lags behind in this regard.
If the Internet does not work via cable from the router. Again, it all depends on the symptom. It may also be that the system was unable to install the network card driver. You need to check and, if necessary, install it.
If you previously configured a connection to your provider (high speed), but after reinstalling Windows 7 it is not there. This is quite normal. It is advisable to first check if there are any problems with the network card driver, then simply create a connection to the provider.
And if you have Internet via a 3G USB modem, then you must install the modem driver, and again, set up a connection to the provider.

Now we will look into everything in more detail and solve problems with connecting to the Internet after installing or reinstalling the operating system.

Why doesn't Wi-Fi work after installing Windows 7?

And so, we installed Windows, we look at the Internet connection icon, but it is not the same as it was before. No connection available Wi-Fi networks, and we cannot connect to the Internet via Wi-Fi. Most likely, the connection status will be like this (if the network cable is not connected):

The fact is that there is no Wi-Fi at all. There are no networks available, and chances are you won't even see a wireless adapter. And all because Windows 7 simply could not install the driver on the wireless adapter that is installed in your laptop, and which is responsible for Wi-Fi work. How many times have I reinstalled Windows 7 on different laptops, and the Wireless adapter driver always had to be installed manually.

It's very easy to check. Just go to the device manager and take a look. You can open it in different ways. The simplest one: open Start, paste it into the search bar mmc devmgmt.msc, press Enter. Or via "Run". You can also go through “Computer” - “Properties” - “Device Manager”.

In the manager we look for the tab Network adapters. And there should be an adapter with “Wireless” or “Wi-Fi” in its name. Like this:

If you do not have such an adapter, or you do have one, but with a yellow one exclamation point and the status “The device is not working correctly”, this means that you just need to install the necessary driver, and everything will work. In this case, in the device manager there must be at least one " unknown device". This is our Wireless adapter.

The main thing is to install the driver for your laptop model (adapter), and for Windows 7 (in our case). I won't write about this in detail here. Already have detailed instructions about . After installation, you will be able to networks.

Internet via cable does not work after reinstalling Windows 7

If you have an Internet connection via network cable from the router, or directly from the Internet provider, but without any settings, when there is no need to create a connection, then first of all we check the network card driver. It also happens that Windows 7 cannot install it either. This is the case when the computer does not respond to cable connection (the icon does not change). And if he sees the connection, but it is “Without access to the Internet,” then look. But this is unlikely.

And so, go to the device manager (how to log in, I wrote above), and on the same “Network adapters” tab we should have a network card. I have this "Realtek PCIe GBE Family Controller". Your name may be different. It all depends on the manufacturer.

If you do not see a network card adapter there, then as is the case with wireless adapter, you need to install the driver. If you have a laptop, then look for the model on the manufacturer’s website and install the driver for the LAN adapter. You can search by the name of the adapter itself. Also, the driver is on the disk that may have come with your computer.

Well, check all the cables, maybe you are connecting something incorrectly.

Lost high-speed connection to ISP on laptop after reinstalling Windows 7

In this case, you just need to create this connection again. Connect the cable from your provider to your computer's network card (it's most likely already connected). If your computer does not respond to the cable, or you are unable to create high speed connection, then check if everything is ok with the network card driver. I wrote about this above.

To create a connection to your provider, click on the Internet connection icon and select “Network and Sharing Center.” Next, click on “Set up a new connection or network.”

Select "Connect to the Internet" and click "Next".

Select "High Speed (with PPPoE)".

Enter the username, password, if desired, check the “Remember this password” checkbox, you can change the name of the connection, and click on the “Connect” button.

Connection information: username and password, issued by the provider. If you also need to register IP and DNS addresses, you can do this using , in the properties of the adapter “Local Area Network Connection”.

Internet does not work via 3G USB modem after installing Windows

As with other connections, you need to install the necessary driver for the modem and set up a telephone connection to the operator. It’s difficult to give specific advice here, since everyone has different modems, and different operators. You can see the instructions for setting up a connection via a 3G modem.

Installing the 3G/4G modem driver

Everything is simple here. The driver may be on a disk that you may have been given when you connected to the Internet. There are many modems on which the driver is built into the modem itself. To check, connect the modem to your computer and go to "My Computer" (just "Computer" in Windows 7). There may be a drive or disk drive that appears after connecting the modem. We tear it off and start installing the driver. Sometimes, a prompt to install software appears immediately after connecting the modem.

If these methods do not work, then look at the modem model and look for a driver on the Internet. Your operator's website should also have the necessary drivers.

Setting up a telephone connection

Once you understand the drivers, you need to create a connection. I don’t know how it is with all the operators (Beeline, Yota, MegaFon, etc.), but with Intertelcom, you need to create a regular telephone connection with a number, username and password.

To create it, go to "Network and Sharing Center" and select "Set up a new connection or network" (see screenshots above). Next, select “Set up a telephone connection.”

Specify the necessary parameters provided by the provider (number, username, password). The computer will be connected to the Internet and a connection will be created. If an error appears that “Windows cannot detect the modem,” then check the modem driver. Or, to start, just restart your computer.
