How to activate the Wi-Fi adapter?
In the event that all your attempts to find a wireless network failed, we can assume that the Wi-Fi adapter is simply turned off on your laptop. Accordingly, the following actions will activate it.
Activating the adapter using the keyboard
As a rule, most functions on a laptop can be activated using the keyboard. If you pay attention to the layout of F1-F12, you will see a set of icons, each of which relates itself to a particular function. So, for example, most often the Wi-Fi adapter icon is located on the F2 key, and it looks like this:
Most likely, in your case to turn on the Wi-Fi adapter, you will need to hold down the special Fn key, and then press F2, after which the screen will display a message that the adapter has been activated or, on the contrary, turned off.
Activating the adapter using the Windows menu
In the event that you have not managed to find the key responsible for activating the Wi-Fi adapter on the keyboard, you can try activating it through the Windows menu.
To do this, click on the icon in the lower right corner of the screen. network connection. A small window will appear on the screen, in which you need to click once on the item "Wi-Fi" so that he had status "Enabled".
Wi-Fi adapter does not work after reinstalling Windows
In the event that you reinstall Windows, and then the Wi-Fi adapter stopped working, with high probability you can say that the computer does not have the necessary drivers, which ensure the normal functioning of the equipment.
1. First of all, to check it, open the menu "Control Panel"and then go to section "System".
2. In the left pane, select "Device Manager".
3. In the popup window, expand the tab "Network adapters". As a rule, network adapters of two manufacturers are installed in laptops: Atheros and Broadcom. If in the expanded list you do not see the names of one of these manufacturers or the list of network adapters is “Unknown Device”, then the case is really in the drivers, the problem with which you need to be fixed.
4. You can download the necessary drivers from the official website of the manufacturer of your laptop. To do this, go to the site and, using the built-in search, find the section dedicated to your laptop model.
5. On the desired page, you will definitely find a section with drivers and utilities. As a rule, the driver for the adapter is hidden under the item "Wireless" (do not forget to take into account the version and bitness of the operating system).
6. After downloading the necessary drivers, you will need to unpack the archive, and then run the distribution and install the drivers. As soon as the installation comes to an end, you will need to restart the computer.
Actually, if, after rebooting the computer, you again look in the “Device Manager”, you will see in the list of network adapters the name of the device for which we installed the driver. As a rule, after these manipulations, the problem with the inoperability of the Wi-Fi adapter disappears. If in your case it remains relevant, try returning to the activation methods described in the article above.
