Installing the Windows 7 operating system takes a little time. After reinstalling it on a computer, each user is faced with the fact that they need to download all programs, restore settings, connect devices such as a printer, router, etc. But, despite all the connections, a situation often arises when the Internet does not work after installing Windows 7.
Why the Internet does not work after reinstallation
This can happen with any operating system, but in most cases, after installing Windows 7, it almost never installs a driver on a Wi-Fi router, and therefore it will not work because of this. Also, the reasons may be due to problems with the equipment or because of the Internet provider.
No adapter driver
Usually after the device should be connected automatically, but the driver from the adapter manufacturer will create the best conditions for its operation.
The most common reason that the Internet does not work is an incompatible or incorrectly installed driver. And in order to understand if your computer has this problem, you should:
- Log in to the control panel.
- Open network connections.
- Now we check the presence of a connection on the local network, if there is one, then we go to the "Device Manager" and check the activity of the driver for the equipment. If it is not active, then there will be an exclamation mark next to the router icon.
In the case when in "Network connections", then the device is not connected, and if it is not in the "Device Manager", it means that it is not working or the system simply did not detect it.
Missing settings or connection
Often, in order to enter the Internet, they use a local network and the providers from which you buy the Internet require network card settings. Therefore, you need to see if you have entered the connection settings. To do this, go to "Network Connections" and select connections over the local network, then click "Details". There we look to fill in such fields as IP address, mask, gateway. If any line is empty, then you need to fill it in manually.
We do it like this:
- go to the "Control Panel", then "Network Connections";
- left-click the activation of "Local Area Connections" and "Properties";
- then we find the protocol "TCP / IP" and click on "Properties";
- enter provider settings.
If the Internet does not work for you after reinstalling Windows, then in most cases there may be 2 reasons:
- When reinstalling, the drivers were deleted (most often).
- Providers themselves block the Internet, thinking that this is unauthorized access to the network from another computer under your login.
- The disk was formatted, a new OS was installed, and the drivers for your hardware are not included in the standard Windows set.
- An assembly of Windows was installed in which someone specifically disabled the “extra” standard drivers, in his opinion.
- If the light is on, then everything is OK with the iron.
- If it is not lit, the network card is not working or the cable is damaged.
- Look for the communication module to be active: the Wi-Fi LED on the laptop keyboard or the network indicator in the tray (for Windows clock).
- The operation of the 3G modem is also determined by the flashing LED.
- Use the driver disk. It should remain with you after buying a PC, most often it is a disk from the motherboard in which the network is built. Just install drivers for a network card or Wi-Fi software.
- Search for drivers on the Internet from another computer. 1) if a laptop, then enter its name in the search, for example, “Laptop Lenovo M3070 drivers”; 2) if a desktop PC, enter the name of the motherboard in the search, and look for drivers for the network card.
- 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 boot, and only then insert the USB modem.
- Wait a little. An operating system notification about new hardware should appear.
- After that, a window will pop up with the ability to install a program to work with a USB modem.
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 the "disappearance" of drivers may be the following:

Sometimes, due to certain life circumstances, it is necessary to install an operating system. Quite often, users find that the sound has disappeared after reinstalling the system.
The likelihood of the situation that after installing Windows 7 the sound disappeared, alas, is far from uncommon. Fortunately, it is solved quite simply, if you know exactly the cause.
Possible reasons
There may be several reasons for the sound to disappear. The main ones are hardware errors, that is, a violation in the sound card. In this case, specialized assistance is indispensable. Or problems in the software part, and specifically, in the absence of drivers for the sound card.
If the problems are with hardware, then you are unlikely to be able to solve the problem without special equipment and skills. Solving the problems of the software part is much simpler and does not require special knowledge and skills. To do this, you just need to confidently use a computer and not be afraid of it.
Solution options
So, if after installing Windows 7 there is no sound, then the first thing to do is to check the connection of the audio system to the computer, and also that the audio system that you are using is selected in the settings. The check is as follows:
In the event that the audio system is turned on and used, but there is still no sound, then the most likely reason why the sound may disappear is that after reinstalling the seventh Windows, the drivers for the sound card or audio device were not installed. This problem is not so terrible and quite easily solved.
Finding and installing drivers
There are several ways to return sound after reinstalling Windows, the easiest way is to install control software distributions from the media that came with the device, it has all the necessary drivers. But if it so happened that there is no disk, you can install the drivers using standard Windows tools.
So, in order to convince the OS to reinstall the drivers, follow the path indicated in the address bar of the explorer: " Control Panel» → « system and safety» → «». And select " device Manager».
After completing these steps, the following window will appear:
In the window that appears, select " Sound, video and gaming devices” and from the list that opens, select the desired system by double-clicking on the name. A properties window will appear, in which you need to select the " Driver».
In this window, you need to select the button Refresh ..., and in the window that appears, click on the item " Automatic search for updated drivers". After that, Windows will start searching for the program on the Internet and update or install it, if such a need exists.
Manual installation
If the built-in Windows service told you something like “The installed software for this device does not need to be updated”, then this does not mean that you really have it installed and do not need to be updated.
If you just installed the system, then there are no audio drivers there. And the system just crashed. Also, quite often the automatic update service cannot find the required software, in this case the direct path is to manually search for and install the necessary programs.
To do this, the first step is to decide which sound card you have installed. If your card is integrated into the motherboard, then most likely it is from Realtek, which means that you need to go to the manufacturer's website and download the necessary software there. The device manager defines built-in maps as High Definition Audio Device.
But since you may have another audio card, it's better to find out in advance which one. For this, we follow Start, we find " Run"and write in the search bar" dxdiag"and click OK.
In the window that appears, go to the tab " sound" (sound).
Line " Name» (name) will tell you which card you have installed. After that, we already boldly go to the manufacturer's website and download the latest version of the software for our card.
After installing the software, restart the computer and check for sound.
Using driverpacks
If you have already tried everything, but after reinstalling Windows 7, the sound still does not work, then you have two ways. The first is to take the computer to a service center or use specialized software to install drivers, for example,. It is better to download it from the official site.
After starting, the program will diagnose the system and indicate those drivers that need to be updated. It will also select the recommended software for installation. Among other things, it will Avast And Yandex browser if you don't need this happiness for nothing, find the button at the bottom of the window Switch to expert mode and manually configure what should be installed.
Feel free to install the recommended drivers, but the software and programs that DRP offers to delete, it is better to review and change the settings to those that suit you. The program can remove something you need.
Problems with the Windows 7 Sound Service
Sometimes the drivers are really in order, and the problems arise because the audio service does not start. First, try changing the system sound a couple of times:
Hardware problems
If all the previous methods did not bring the desired result, then most likely there are violations in the operation of the hardware. An audio card may fail due to the failure of some individual elements, and not the entire board as a whole. But this will not calm the owners of integrated cards at all. Built-in cards are not repairable, so if it fails, you will have to buy a discrete sound card.
Discrete cards are usually repairable, but you should not try to fix this device yourself without the appropriate skills and equipment, most likely, you will only aggravate the situation and spend much more money than if you gave the card to professionals.
Reasons for rejection:
- overheat;
- burnout;
- raw contacts;
- breakage of conductors;
- broken plugs;
- departed soldering;
- developer error or manufacturing defect.
To prolong the life of your computer, clean it several times a year. This will allow the cooling system to perform its function most efficiently and problems such as overheating and wet contacts will most likely not affect you.
However, the lack of sound is not always the result of a failed audio card. The first step is to check the performance of the audio system, for this, simply connect other speakers to the computer.
Cords can also fail, the replacement of which is not difficult, especially for headphones.
It is not always possible to determine whether the audio card is really out of order or there are problems with another device at home without equipment. Therefore, do not immediately panic, it is best to diagnose at the service center, as well as update the computer software.
