Do not connect WiFi on the laptop - nothing terrible happened!

A fairly common problem to date is that WiFi is not connected to the laptop. Usually, the lack of data transfer via the wireless interface is due to incorrect software configuration. The first item on this list is the accidental disconnection of the adapter on the keyboard or with a special toggle switch on the case. Next, you need to check the driver (the program that manages the adapter) and, if necessary, reinstall it. At the last stage we check the network settings. Phased The performance of all these items in most cases allows to eliminate such a problem when WiFi is not connected to the laptop.

Turn on the adapter

The keyboard of most modern mobile PCs has an expanded functional keyboard. It can be activated by pressing a special key - "Fn". In this case, the standard character set stops working, and you can only use the additional one. It includes a key with an antenna and waves that move to the sides. On most models, it is in the functional set "F1" ... "F12". If you press "Fn" immediately and do not release its key with the antenna and the outgoing waves, an inversion of the current state of the adapter will occur. If it was turned on, it will turn off. To restore it to its original state, you need to press the previously mentioned key combination. It is important to pay attention to the LED indicator WiFi. If it is off, it will need to turn on, then the adapter will be on, and data transmission will be possible.

The second possibility of turning off the wireless network card is with the help of the toggle switch. The principle of operation is similar to the previously mentioned one, with the same combination on the keyboard. When you transfer it from one position to another, the picture will be similar - no WiFi is connected to the laptop and the corresponding indicator is not lit. To turn on the adapter, it must be reset. Depending on the model Mobile PC, can be used as the first or the second way of shutdown. In premium models, their combination is possible.

Checking the driver

Next, you need to check the correctness of the network adapter driver installation. Its failure can lead to the fact that the laptop does not connect to WiFi. First you need to find the disk that comes with the device. If it is not, then download the installer from the official manufacturer's website on the Internet. Then go to the address Start \ Control Panel \ Device Manager. Then open the item "Network adapters" and look at the wireless card. If there are no icons opposite it, then we proceed to the next stage. Select our wireless adapter with the left mouse click and press "Del". This removes the existing driver. Then run the installation of new ones from the disk or the downloaded file. After that it is recommended to reboot the system. If this did not solve the problem, we proceed to the next stage.

Verifying network settings

At the final stage, we check the connection settings. To do this, we open
Double-click the left mouse button "Current connections" (a shortcut with increasing chopsticks on the right side of the taskbar). In the opened list, select the properties of the required network connection. Next, you need to check the type of encryption (it should be the same as on the router) and the password for access. If the password is accidentally changed, then you need to check the PC for viruses. After all three stages, such a problem, when WiFi is not connected to the laptop, is solved in most cases.

Conclusion

If all the operations outlined in the article are completed and the result is not reached, then it makes sense to seek the help of a qualified specialist. As practice shows, in most cases, the proposed manipulations allow to solve such a problem, in which the laptop has stopped connecting to WiFi, and transmission over the wireless network is restored.
