I reinstalled the system and the internet does not work. Installing a driver for a wireless network. Incorrect settings: IP, default gateway, DNS, etc.

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

When reinstalling, the drivers were removed (most often).
Providers themselves block the Internet, thinking that this 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.
A Windows build was installed in which someone specifically disabled what he considered to be “unnecessary” standard drivers.

Eliminate hardware problems

Internet not working after reinstalling Windows? First, check the hardware, look at the network card on the back of the 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 wireless Wi-Fi 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 keep it after purchasing a PC; most often it is a disk from the motherboard, which has a built-in network card. 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 M3070 laptop drivers”; 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 for network devices (modem, network card) are installed. 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”.

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 for the OS to fully load, 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.

Typically, mobile Internet operators 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, contact the provider’s technical support.

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.

Often, after installing a new version of the Windows operating system or reinstalling an old one, the problem of lack of Internet connection via the Wi-Fi module may arise. That is, your netbook or laptop does not interact with the Wi-Fi router. What to do in such a situation, and what are its reasons? Try going to " Sharing Center", there you will find the icon " Wireless network connection" This is where the fun begins, because in most cases it is missing. This is a consequence of the fact that the necessary driver is not installed on the computer. Of course, after you reinstall the Windows operating system, all drivers from your laptop are lost and must be reinstalled again. Therefore, the fact that the wireless connection driver also disappeared is not surprising. To prevent this from happening in the future, before installing Windows, check whether you have all the necessary drivers on your disk or flash drive. If not, use the Internet to find them. Typically, such drivers come with your computer or other device.

How to connect Wi-Fi and fix internet connection problem?

To make your wireless Internet connection work again, reinstall the required driver. This is very easy if you still have your original disk with specific settings (as a rule, it is included in the kit). If it is impossible to install the driver this way, then simply download the necessary program on the Internet. They may be on the manufacturer's website. There are different drivers, this must be remembered. What is created for one is not quite suitable for another. Therefore, try to download software designed specifically for your model. After completing the installation and entering new parameters, you can safely connect the router. As a rule, in such cases the Internet connects automatically.

Many users of the World Wide Web from time to time encounter a situation where the Internet does not work after reinstalling Windows, although everything was done according to the description, as on the website, or in the provider’s instructions. Below are tips that should help the user identify the source of the problem and solve it.

In general, for the Internet to work on a computer, you needfunctional and configured equipment for the Internet. To connect to the Internet, modems can be used (telephone modem, USB modem of a mobile operator, modem of a mobile phone or smartphone, ADSL modems), wired and wireless (Wi-Fi) network cards, satellite Internet cards .

Network connection to the Internet.

The most common Internet connection is via a network card to a high-speed ADSL modem or computer network with Internet access.

First, check whether the green light on the network card is on or not. It is located right next to the connector into which the cable is inserted, on the back wall of the computer case (where all the other wires are). If the light is on, then there is a physical connection between you and the equipment of the Internet service provider, but if it is not on, then try disconnecting and inserting the cable. If this does not produce results, then the problem is purely physical, and you need to call the provider’s technical support to call the technicians.

So, if the light does not light, there is no connection with the equipment: either the equipment is faulty, or the network card, or the cable.

Wireless Internet connection.

When using a Wi-Fi connection, make sure that the equipment is turned on: by the LED on the laptop keyboard or the network indicator in the area near the clock.

The 3G modem will also indicate its functionality with a blinking LED.

Telephone modem connection.

Make sure there is a dial tone on the telephone line. Find out how else you can connect to the Internet.

Modem connection of a mobile device.

Check the battery charge. Use a cable to connect instead of Bluetooth.

Network equipment drivers.

The light is on, but the Internet still does not work. Then you need to launch the “Device Manager” by opening the “Control Panel”, clicking “System and Security” and selecting the appropriate sub-item from the “System” item. Carefully examine the list of devices that appears on the screen for missing drivers (they will be highlighted from the general list).

Install drivers on all devices on your system without exception., using the installation disk included with the motherboard (if the network card is external, the disk will go to it separately). To do this, right-click on the device (for example, on a network card) and click “Update drivers...”, then in the window click “Search for drivers on this computer” (not automatically) and select your DVD drive as the installation path, click "Further". The process of searching for the required driver and installing it into the system will occur. If any errors occur, check the compatibility of your equipment with your operating system. When installing drivers, you may need a disk with the operating system.

More details about installing and searching for drivers Usually, after reinstalling the operating system, in addition to drivers, you need to install the latest versions of DirectX (graphics), codecs (watching movies) and Microsoft NET.Framework (networking).

Windows operating system network services should be running!

By default, all necessary services are launched automatically, however, when using assemblies or tweaks, some network services may be disabled.

If the drivers are successfully installed, but the connection still cannot be established, or the pages do not load, then launch the “Control Panel” (via “Start” - “Control Panel”), and then select “System and Security”. From the list that appears next, select “Administration” and then “Services”. Make sure the services are enabled and running: "DHCP client", "DNS client", "Remote Access Connection Manager", "Computer Browser", "Network connections", "SSTP Service", "Network Saving Interface Service", "Connected Network Information Service", "Network List Service", "Telephony". If these services work, then all types of wired Internet should function, so you can safely set their launch mode to “Auto” (right-click on the service and “Properties”) and, after restarting the computer, they will start on their own. If some of them do not start after the restart, you may have an incorrect build of Windows.

If the Internet connection is configured and connected, but the browser reports an error opening the page:

Use the instructions to create a connection from your provider, enter your login and password correctly, set all the necessary settings (your IP address, IPproxy and DNS server addresses).

If all of the above did not lead to the desired outcome - there is still no Internet - then perhaps your account is blocked by the provider due to a negative account balance, or your IP is blocked for security reasons (sometimes this happens due to the fact that the newly reinstalled system is perceived on the provider’s side, as an attempt to connect to the network using someone else’s login and password). Also in the modem settings and in the provider’s equipment, it is possible to bind to the MAC address of your network equipment. Perhaps you have a new network card, and, accordingly, a different MAC address. In any of these cases you need to call the company's technical support that provides you with Internet services.

Watch the video on YouTube: “After reinstalling Windows, the Internet does not work”.

The Internet may not work after reinstalling Windows 7 for a number of reasons:

During the reinstallation process, software for the network equipment was removed;
The provider mistakenly blocks the connection, believing that unauthorized access is being carried out from someone else's computer using your credentials.

Check if the provider's services have been paid for!!!

The first may be caused by the fact that the hard drive was formatted during the installation process. The basic software package may not be suitable for the network equipment you use. Often, certain builds of Windows 7 do not include the drivers required for working on the Internet.

In the second scenario, in order to restore the connection and stabilize the Internet after reinstalling Windows, you will need to contact the service provider by phone number. The provider's technical support should resolve the problem as soon as possible.

So, after reinstalling Windows 7, the Internet does not work. Before starting to study the software part, we will rule out possible problems with the technical part. For this purpose, it is recommended to check the functioning of the network card:

If the special indicator light in the card slot is on, then the card is OK;
When the indicator is silent, it is recommended to check for a breakdown in the cable or check the card itself - it may be faulty.

If after installing a new version of the OS there is no Internet, then it is important to check the wifi module - router or modem (if access to network resources is provided through it):

Equipment activity can also be examined by checking indicator lights. If the special diode on the laptop keyboard is active or the system clock indicator in the lower right corner is OK, then the router is functioning stably;
For modems the situation is similar.

What to do if the hardware is faulty?

Important!!! Check the Ethernet controller driver

To connect to the Internet, which disappeared after a clean installation of the OS, you can choose two ways:

Use a disk containing basic software for network equipment. Such a disk must be available after purchasing the computer;
You can also install software downloaded by using another computer or laptop. If you plan to set up a laptop, then enter its name and model into the search engine. To find drivers on a PC, you only need the model and manufacturer of the motherboard.

The best option is to visit the website of the manufacturer of the laptop or motherboard or the Ethernet controller (network card) itself.

By selecting drivers you can

Regarding the settings

After installing all the necessary driver packages and checking for serviceability or malfunction of the network equipment, the urgent question becomes how to set up the Internet.

If the connection is made directly: a cable is plugged into the corresponding socket on the back wall of the PC, then it is recommended to follow the instructions:

Through “Start” we access the “Control Panel”;
Now, through the “Network and Sharing Center”, go to “Set up a new connection”;
A window will appear on the monitor with options and types of connections. When making an ADSL connection, you will need to select “Internet Connection”. When you plan to connect via 3G, the choice should be made in favor of “Telephone connection settings”.

For the first case, after selecting “Internet Connection”, we turn to the “High-Speed” type. Enter all the required values. If the equipment is in good working order and the software elements are installed correctly, the connection will acquire the “ready for use” status.

Next, for convenience, it is recommended to create a shortcut and place it in a convenient place for access. Through the “Control Panel”, go to the “Network and Sharing Center”, then to “Change adapter settings”. Having selected the recently configured connection and accessed its properties, we create the required shortcut.

Setting up the router

If access to Internet resources is carried out via Wi-Fi, and a computer with reinstalled Windows for certain reasons does not see an active connection, then the main and main task of the PC user is to find software for the network card or the module itself that distributes the signal. We talked about how best to do this at the beginning of the article.

If you do not have experience working with the settings of routers of various models and suppliers, it is recommended to first study the relevant materials or enlist the support of a wizard: there are often situations when, after reinstalling the OS, for one reason or another, the settings of the wi-fi module are lost.

More detailed information about self-configuring routers of various models

Modem users

Brief instructions on how to connect a USB modem:

USB devices must be connected to a computer or laptop strictly after turning it on and waiting for it to fully boot;
After some waiting, the system will issue an interactive notification about the detection of new equipment;
Next, the computer will prompt the user to install an environment that allows unhindered work with the modem.

Modern models are created by service providers in such a way that all the necessary services - automatic configuration and dynamic IP address - are already implemented in the device. This means that the user will not need to perform additional manipulations. However, a situation may arise when the network does not appear on a working computer after connecting a USB modem. In this case, it is recommended that you review the accompanying documentation or contact the service provider's technical support directly.

Summing up

In this article, we examined the most common scenarios for the behavior of network equipment after a clean installation of Windows 7. It is worth noting: often many users easily connect to Internet resources, while others encounter difficulties, the solution to which is described in the article.

In conclusion, we recommend that users download, save and update Driver Pack Solution in advance. Its peculiarity is that it is capable of searching for and installing drivers that are missing on the PC. An alternative is to store on removable media the most necessary and current versions of software not only for network equipment, but also for all other components of your personal computer or laptop.

When using a computer for a long time, any user sooner or later becomes puzzled by the fact that the system is cluttered, residual files do not want to be deleted voluntarily, and the laptop boots up at the speed of a wounded snail. Also, some viruses, although treatable at first glance, still leave their tiny traces. Subsequently, it grows exponentially and affects the entire system completely. Therefore, the user begins to ask the pressing question: “How to reinstall Windows 7?”

Of course, to solve these problems, you can use the services of plugins or start using a new antivirus, but such a solution will be temporary, and in a few weeks the situation will not only repeat itself, but will also worsen. In addition, sometimes the computer simply leaves no choice, threateningly greeting you with a “blue screen of death” with farewell instructions.

Reinstalling the operating system in a specialized salon costs a lot, so today we will save a couple of thousand and learn how to reinstall the OS ourselves. But before you reinstall Windows 7, there are several steps you should take.

Preparing and saving data

How to properly reinstall Windows 7? In order to protect yourself from losing important files after reinstalling the system, it is worth spending a little time and saving on a flash drive or disk those documents that may be needed in the future.

For example, not everyone wants to lose their achieved results in their favorite game. You just need to find and save one small file, which is located in the AppData folder of the user. If a folder with this name is not displayed, you need to go to “Computer” - “Local Disk” - “Users” - “your name” and there click on “Arrange”, then select folder and search options in the drop-down menu.

And put the checkbox on “Show hidden folders and files”.

How to save favorites and links from the browser

For the Mozilla Firefox browser, you will need to go to “Local Disk” - “Users” - “Username” - “Favorites” and save the entire folder.
To save Google Chrome data, go to “Local Disk” - “Users” - “User Name” - “AppData” - “Local” - “Google” - “Chrome” and save the User Data folder.
For Internet Explorer, it is enough to save the “Favorites” folder located in “Local Disk” - “Users” - “User Name”.
When working with Opera, we go to the well-known path to the AppData folder and then Opera, you only need to save the bookmarks.adr file.

Saving torrent files

To save torrent files, go to AppData, find the uTorrent folder there and copy it completely. After reinstalling the system, the saved folder must be placed in the same location. This also applies to saved games and bookmarks in browsers.

When all the necessary data, photographs and other necessities have been successfully saved, we begin reinstalling the OS to the beat of the drums.

How to properly reinstall Windows 7

If you have a disk with an operating system, then insert it into the drive, after which the automatic reinstallation of the OS should begin, although in 60% of cases this does not happen. What to do in such a situation to understand how to reinstall Windows 7? “BIOS” is a mystical word, upon hearing which many begin to get nervous. In fact, there is nothing wrong with the BIOS if you don’t touch anything unnecessary (and even in this case, all parameters can be restored). In order to get to your destination, you need:

restart the computer;
Press the del key 2-3 times until the Windows splash screen appears. If the transition to the BIOS does not occur, simply repeat the procedure again.

So, if everything is done correctly, the following image should appear before your eyes:

Next, find First Boot Device and set the value to CD-ROM. This means that when your computer starts, it will automatically load data from the disk first. It is very important after installing the software not to forget to return everything as it was, or the computer will continue to install the system forever (if you also forgot to remove the disk).

Press f10 to save changes. If all conditions have been met, the system will begin reinstalling.

The next window prompts us to select the language, date and set the time. We set some simple parameters, and feel free to click “next”, “install” and accept the license agreement.

type of instalation

Upgrade - suitable only if the system is reinstalled for minor reasons. If the decision was made in connection with the “screen of death” or if malware is clearly installed on the computer, we definitely choose a full installation.
Full installation (custom) - reinstalls the OS literally from scratch, mercilessly destroying everything that can harm it.

Disk configuration

Here you have to choose which disk will appear as local, i.e. the one on which the software will be installed.

Logically speaking, the volume of the system disk should be within 35 GB, but not less. It’s worth considering that many of us like to save files using the “throw it on the desktop for now so as not to forget” principle. All documents, pictures, etc. that are located on the desktop are stored on the system drive, as well as files from the “Downloads” folder. Thus, when calculating local disk space, it is worth being more generous.

Click “Next” and go have a snack, we have at least 45 minutes. During installation, the computer will reboot several times, which will kindly warn you. You shouldn’t interfere with this; if no unforeseen situations occur during the process, in 45-50 minutes the new Windows 7 will be installed safely.

The next step is the username and computer name. If at some point you need to change these settings, this can be done simply: “Start” - right-click on “Computer” - “Properties”. Find “Computer name, domain name and workgroup settings” and click “Change settings”.

It is not necessary to set a password, so you can skip this step by clicking “Next”.

You will also need to enter your product key. You can find it on the bottom of the laptop or on a special sticker on the system unit (if you purchased the equipment along with a licensed disk).

If the software was installed from another disk, then the key should be indicated on the box. Well, if the system was installed illegally, you can skip this point and forget about this issue for about a month. After 30 days, the beautiful picture on your desktop will be replaced by a black screen, and some functions and devices may be disabled. If this doesn’t bother you, then you can safely work with the system further or be puzzled by searching for a suitable key on the Internet.

When choosing the type of update installation, it is best to use the recommended settings. If the system is not automatically updated, then sooner or later minor problems may arise in working with the most frequently used programs. The update eliminates minor bugs and optimizes the operation of the OS.

How to reinstall Windows 7 without a disk or from a flash drive

Sometimes it happens that there is no disk with Windows, or the CD-ROM is blind and categorically refuses to cooperate. Don't despair, there are no hopeless situations. There are several ways to install the system using other media. For example, you can reinstall Windows 7 from a flash drive.

Reinstalling the system using a flash drive

First, download the OS image to your computer. After this, install the Ultra Iso program or you can use Daemon Tools, the algorithm is approximately the same.

Next, take a flash drive or memory card, but it’s worth noting right away that the BIOS will not see any of the drives installed via the USB-3 connector, so be careful and use USB-2. Externally, the connectors do not differ; in some devices, USB-3 is marked in blue. If there is no identification mark, then everything is simple. We find in any search engine information about the characteristics of a laptop or computer and then information about which side the connectors we need are installed on.

In order to prepare a flash drive for further work, it must be formatted, even if there is nothing on it. Next we perform the following steps:

In UltraIso, open the Windows 7 image that we have already downloaded (“File” - “Open” - select the program image).
Find “Self-upload” in the top menu and select “Burn hard disk image.”
In the window that opens, indicate the formatted flash drive.
We confirm the check, and set the recording method to USB-HDD+.
Click “Record”.
We agree with the fact that all files will be erased from the flash drive (even though we formatted it, we still set it to “Yes”).
Voila! If we see “Recording complete”, then the job is done and you can start reinstalling.
We go to the BIOS in the known way described above, and in First Boot Device we select the recorded flash drive.

Reinstalling Windows 7 using an image recorded on a DVD disc

Another method will tell you how to reinstall Windows 7 via CD-ROM without a license disc.

Why DVD? Everything is elementary, a regular CD will not work for one simple reason - there is not enough space, and the OS image “weighs” about 3 GB.

If for these purposes you decide to use a DVD that already has something on it, then, as in the situation with a flash drive, you need to resort to formatting.

Now open the already well-known UltraIso program, go to “File” - “Open” and find the downloaded Windows image.

Next, go to the “Tools” menu and click “Burn CD image”, in the window that appears, check the “Check” box, humbly accept the fact that everything on the disk will be destroyed and click “Burn”.

That's all, after the message “Recording complete” appears, our disk is ready. We think everyone has already guessed what to do next. That's right: go to the BIOS and select the recorded disk as First Boot Device.

How to go back from Windows 7 to XP

Sometimes it is difficult for users to master a new system, so for some it is easier to reinstall Windows 7 on XP. The installation procedure is not much different from that described earlier, with the exception of a few points:

After proceeding to the installation, the system prompts you to select which partition (that is, which disk) the OS will be installed on. In order to completely destroy a previously installed Windows 7, you need to select the appropriate partition. After this, there will be 4 formatting options to choose from, the only correct one of which is “Format partition in NTFS system”. After this, the computer usually restarts and begins installing the system.
If there is a strong desire to install two operating systems on one computer or laptop at once, then, on the contrary, select the partition that is not occupied by system files. This is usually drive D.

Reinstalling Windows 8 to 7

Despite the fact that the majority of users positively assessed the seventh version of the software from Microsoft, the “eight” received rather contradictory responses. Since the newest version is fundamentally different from all previous ones, sometimes there is a desire to replace the OS.

In order to reinstall Windows 8 to 7, you will need to go into the BIOS and set the primary priority to the CD-ROM (how to do this was described earlier).

After this, save the changes and proceed to boot from disk or other media. The installation type when changing Windows 8 to 7 can only be “New installation”, since the OS is different, there is no need to talk about any updates.

It is also necessary to delete all partitions, including hidden ones. After that, without thinking any more about how to reinstall a Windows 7 computer, we do the rest:

indicate the time, date and keyboard layout;
agree to the terms, indicate the user name and computer name;
enter the key, etc.

After installation (drivers)

As a rule, reinstalling Windows 7 on a laptop or computer is quite easy, but after the process of replacing the OS, many users have a number of questions. For example:

“Why did the image quality deteriorate after installing the new system?”
“Why doesn’t my computer or laptop see the flash drive?”
“Why has the sound gotten worse?” etc.

All this happens most often when the reinstallation was carried out by downloading the OS or purchasing a disc from someone else (you don’t have to think about how to reinstall a Windows 7 computer, but some “jambs” still pop up). In order to solve a number of similar problems, it is enough to download drivers from the manufacturer’s official website. Or pay attention to the drivers before reinstalling the system.

Let's look at it with an example. Let's say that before reinstalling Asus Windows 7, the user was not puzzled by the issue of saving data from his laptop, or he simply did not have the opportunity to do this. What should I do?

It’s simple, just type in the search engine the model (the manufacturer’s company is enough) of the device and add the treasured phrase “Download drivers from the official website.” Then go to the link of the manufacturer’s website and indicate the full model of the laptop in the appropriate form. Next, you need to download all the presented drivers one by one and install them on the laptop one by one. There are no installation tricks, since the drivers install themselves where they should.

If for one reason or another the drivers have gone wild and are installed in the wrong place, you can go to the device manager and force them to update.

In order to get into the remote control, you can simply type “Device Manager” in the search bar that pops up when you click “Start”. Next, right-click on the driver that is marked with an exclamation mark. And select “Update drivers”, in the new window all that remains is to indicate that the required files must be searched on the computer itself and indicate the location where they were installed.

If all drivers are installed normally in the device manager, the image will improve and the screen resolution will increase to the required level.

Finally

The computer can “fly” at any moment, so you should think about organizing backup storage for high-value files before reinstalling Windows 7. This way you can save a lot of time after installing the system, because it is quite possible that even the most basic programs ( Word, etc.) will have to be searched and installed again.

Reinstalling Windows 7 on a laptop or computer is not difficult; even a novice user can cope with this task. The main thing is to approach the issue responsibly and spend an hour saving all useful information from the computer before reinstalling the OS.
