When operating system reinstalled, the user may encounter the problem of a missing network driver. Without this driver, neither wireless nor wired network can run. If you have a disk, there are no problems, just install the program. And in its absence, you need to find, for example, a mobile phone / tablet with a connected network in order to download the driver. To avoid such problems, when reinstalling the operating system, you must follow the correct algorithm of actions.

The driver is the link between the operating system and the internal components of the computer, that is, this program connects the OS to the motherboard, video and network cards, office equipment. These programs are developed by the same companies that produce PC hardware and electronic office equipment that the personal computer interacts with. When buying a computer, the user does not think about various drivers, since they are already pre-installed in the system. But, for example, after the first reinstallation of the OS or the purchase of a new computer, the user will be faced with their absence.

If there is no driver for the network on the computer, there is no way to go online and download from official sites that will automatically scan the operating system and install all missing drivers. When can you run into a problem installing a network device driver? In these three cases:

1. Even on a new, just from the store, computer, the operating system may be missing, and as a result, the driver.
2. When the operating system is installed/reinstalled.
3. When a system failure occurs and the driver stops working.

The first case is the easiest. In the box with the purchase should be discs with drivers. The network device driver is located on the software disk for the motherboard.

Because in Lately As users increasingly assemble computers themselves (choose internal components), a DVD drive may be missing, and as a result, it is not possible to install any driver from a disk.

In this regard, we can advise you to keep the full set of drivers in a separate folder on your PC or download them to a flash card. In this case, you don't have to search mobile device to go to the official pages of manufacturers' websites and from there download a program that will automatically install the missing drivers.

Installing the network driver

Before installing the driver, you must identify your computer. All brands and models of internal computer hardware are encoded with special "ciphers". This is done so that during installation the driver can identify the computer model and its manufacturer. The network device driver code looks like this: PCI/TECH_xxxx&DEV_xxxx&SUBSYS_xxxxxx. TECH means that the hardware for the computer was made by A4Tech, and DEV is the device ID.

Step 1. Hardware identification

In order to find out the code, click Start, enter device manager in the search field. Next, a menu will open with which you can identify the equipment. Press " Network adapters» and select the name of the controller.

Once you do this, the Details section will open. Find their "Properties" and select "Model ID". The first line contains complete information about the device model.

Step 2: Install/Update Network Adapter Driver

This will be the identifier of your equipment. Now you need to find it on the Internet by entering the name in any search engine, for example.
The search engine will give the official driver page, and you need to download it to your PC. Then comes the installation process itself. If you need to update a network device driver, you do exactly the same: find the ID, enter it in the search, download and install.

To install a missing or latest version of the driver, use the "Device Manager". Do the same for the last step Update drivers».

Select "Search for driver software on this computer".

Go to the folder where you saved the necessary drivers downloaded on the official website of the manufacturer, and install them using the "Next" button.

Many users, before installing new versions of drivers, remove the old ones in order to avoid conflict and inoperability, because even if you did everything correctly, the Internet may not appear on the computer. In this case, you still need to take the advice of users and remove the old versions.

How to do it! In Device Manager, you can uninstall old version network driver. Agree with the choice, and the system will remove the network device driver that was previously installed on your computer.

There are two steps left and your computer will work fully. Step one - reboot and open Device Manager. In place of the removed driver will appear " network controller" In chapter " Other devices».

At the final stage, follow the steps from (updating/installing network device drivers).
