A fairly common problem today is that WiFi is not connected on the laptop. Typically, the lack of data transfer via a wireless interface is due to incorrect software settings. The first item on this list is the random disconnection of the adapter on the keyboard or using a special toggle switch on the case. Next, you need to check the driver (the program that controls the adapter) and reinstall it if necessary. At the last stage, we check the network settings. Phased
the implementation of all these points in most cases eliminates such a problem when WiFi is not connected on the laptop.
Turn on the adapter
The keyboard of most modern mobile PCs has an extended functional keyboard. It can be activated by pressing a special key - βFnβ. In this case, the standard character set stops working, but you can only use the additional one. It includes a key with an antenna and waves extending to the sides. On most models, it is in the functional set "F1" ... "F12". If you press βFnβ right away and without releasing its key with the antenna and the waves extending to the sides, then the current state of the adapter will be inverted. If it was turned on, it will turn off. To return it to its original state, you must once again press the key combination given earlier. It is important to pay attention to the WiFi LED. If it is turned off, then it will have to turn on, then the adapter will be in the on state, and data transmission will be possible.
The second option to turn off the wireless network card is with the toggle switch. The principle of operation is similar to the previous one, with the same combination on the keyboard. When transferring it from one position to another, the picture will be similar - WiFi is not connected on the laptop and the corresponding indicator does not light. To enable the adapter, you need to return it to its original state. Model dependent
mobile PC, both the first and second shutdown method can be used. In premium models, a combination is possible.
Checking the driver
Next, you need to check the correct installation of the network adapter driver. 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 site of the official manufacturer on the Internet. Then go to Start \ Control Panel \ Device Manager. Here we open the item "Network Adapters" and look at the wireless card. If there are no icons in front of her, then we are proceeding to the next step. Select our wireless adapter with the left mouse click and press βDelβ. This removes existing drivers. Then we start 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, go to the next step.
Check network settings
At the final stage, we check the connection settings. To do this, open
double-click the left mouse button "Current Connections" (shortcut with increasing sticks on the right side of
the taskbar). In the list that opens, 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 has accidentally changed, then you need to check the PC for viruses. After carrying out all three stages, such a problem when WiFi is not connected on the laptop is solved in most cases.
Conclusion
If all the operations described in the article are completed and the result is not achieved, then it makes sense to seek help from a qualified specialist. As practice shows, in most cases, the proposed manipulations can solve such a problem in which the laptop stopped connecting to WiFi, and transmission over the wireless network is restored.
