Wi-Fi data transfer. One of the benefits of all portable devices. Data is transmitted at high speed, no wires or additional devices are needed, the connection is very simple: just find the access point, and the computer will do everything by itself. However, even brand new devices may need to set up Wifi. On a Lenovo laptop, this can be done by the user, because, as a rule, it is not a technical malfunction, but the operating system settings.
What to do if Wifi does not work on a Lenovo laptop? Specialists from this company love to equip laptops with various additional buttons, be it NovoButton. button to enter BIOS, or wireless network activity switch. This sometimes causes difficulties for users. Perhaps soon the manufacturer will supply the devices with reference literature, but while it is not there, the owners are looking for information on their own.
How to enable Wifi on a Lenovo laptop? The first way. Use the FnF5 keyboard shortcut. However, some laptops from this company are equipped with additional buttons, the location of which varies depending on the model, but, as a rule, the switch is located either next to the microphone input and headphones, or next to the power button. Third location option. next to the power connector.
If the Wifi power button on the Lenovo laptop is located on the side, it will most likely be in the form of a slider with the ability to switch left and right, but if it is next to the power, it looks like a regular button with a green computer icon. In this case, next to it will be the so-called NovoButton, which is responsible for entering the BIOS and resetting the device to the factory settings. No, clicking it will not immediately restart and return the computer to its original state, so nothing will happen if the user clicks on it accidentally.
However, for example, the Lenovo G580 and some other models do not have such a switch, and users often have questions about turning on wireless networks, because pressing the FnF5 hotkeys does not work either: the mode turns on "In airplane". On some laptops from this company, the FnF2 combination may work, however, if the operating system was reinstalled, the combinations could change. In this case, the easiest way is to see the list of hot keys in the control panel.
How to enable Wifi on a Lenovo laptop if this method does not work? The user must check for the appropriate drivers. The fact is that if you reinstalled the operating system, and the wizard (or the owner himself) was not worried about installing branded drivers, but used the standard ones that came with the package from Windows itself, these hot keys may simply not work. To find out if there is such a problem, you need to make sure that the other F and Fn hotkeys are functional and if there is a Wifi button among them.
The program for the laptop, which is responsible for the operation of the functional buttons, may require a separate download from the official website of the manufacturer.
Enabling Wireless Transmission
If you’ve followed the instructions but Wi-Fi doesn’t work on your Lenovo laptop anyway, check if the mode is turned on "In airplane". In the case of its activation, all connections are disconnected, and often such a simple thing can be the solution to the whole problem. If the mode is not turned on, you need to make sure that the wireless adapter is turned on in the operating system itself. Should press menu "Start" and go into "Control Panel"typing it in the search (in versions of Windows 8 and older, you can use the WinX keyboard shortcut), then go to "device Manager". Expand tab in it. "Network adapters". Depending on the model, the name of the device you are looking for may vary (for example: Broadcom 802.11g Network Adapter, you should look for a similar one).

After the desired device is found, the user must make sure that it is involved: right-click and select "Enable". If it is active, you can turn it off and on again, sometimes it also helps to solve the problem. After reinstalling the drivers or turning on / off the adapter, the device should be rebooted.
Are there any other options on how to enable Wifi on a Lenovo laptop? Yes. uninstall the adapter. In the same menu, right-click on the adapter, but instead "Enable" select "Delete". This does not mean that the computer permanently loses the function of connecting to wireless networks, but it will be necessary to download and install the latest drivers specifically for this operating system and laptop model from the manufacturer’s website.
Most often, this method solves the problem with wireless networks on a Lenovo G580 laptop.
If before Wi-Fi worked
All the previous methods on how to enable Wifi on a Lenovo laptop should cope with the problem if the computer is new and has never before been connected wirelessly. However, if until recently everything was in order, and the laptop detected a network, and now the network icon with a red X is hanging in the tray, and the operating system reports that there are no available connections, the situation may be different. Of course, first you will need to try all the previous methods of solving the problem, and if they do not help, read the instructions below.
This problem is quite common among laptop owners on Windows 7 and later. First, the user must make sure that the router is working, and other devices successfully connect to the wireless network. If everything works, then the operating system of this laptop believes that the Wi-Fi adapter is turned off.
The first step should be to check the activity of the wireless connection in the list of network connections (first you need to go to the Network and Sharing Center, go to the tab "Network and Internet", and from it to the menu "Network connections")
In Windows 8 and older, in the right pane you should find the item "Parameters", Further. "Change computer settings", and in the window that appears, select the menu "Network", but on version 8 of the OS. "Wireless connection". There you need to verify the active state of the wireless modules.
Also, disabling necessary services may be a common problem. Often, users deactivate many components of the operating system to speed up the computer, and this can really help. The fact is that Windows can perform many different tasks, and for each of them certain tools are needed, but the system cannot know which of them at the next moment the user may need, so it keeps most of them turned on. This leads to a slowdown, especially if a small amount of RAM is installed on the computer.
For example, why do you need to keep the printer and fax services turned on if the owner does not need such devices and will not use them? Also, the computer master (or the user himself) can turn off services related to the operation of networks if an Internet connection is not expected, and this significantly speeds up the work.
List of services
Below is a list of the main services without which the Internet connection will not be made or will not work correctly.
- DHCP client: the service is used when connecting. Power on should be selected automatically, but not manually.
- DNS client: must also be installed "Power on automatically".
- Network connections: as the name implies, is responsible for these functions. Can put "Manually"even if the internet is used.
