Make sure that the Ethernet port on your computer is working properly
Connect an Internet cable directly to your computer without using a router. If Internet access appears, the computer does not see the router due to problems with the router itself. Otherwise, if the Internet access does not appear, the error may be due to a problem with the computer‘s network card. It is recommended to reinstall the network card driver or replace it.
Causes of network blindness of mobile computers
If the laptop does not see any access points, does not search for them, and the mere presence in it of support for Wi-Fi is questionable, the source of the problem in 99% of cases hidden in the laptop. In software or hardware.
- Disabled Wi-Fi in Windows.
- Putting the device into “Airplane mode.
- Absence or improper work of the wireless network driver.
- Stop the WLAN Autosetup service.
- Malfunction in the operating system.
- Disconnection, corruption, absence or operation of Wi-Fi adapter in monitor mode.
Using the network module as a monitor requires a special driver, so it’s almost impossible to activate this mode unknowingly. And those who use this feature usually know when it’s active.
If your computer can’t see only one access point but sees others, the cause is most likely in the router’s settings or in the properties of the transmission medium. Namely:
- The access point is broadcasting on a frequency that is not supported by your laptop adapter.
- The transmitting radio channel is loaded with signals from neighboring devices using the same frequency band.
- The SSID (wireless network identifier or name) broadcast is disabled.
- Wi-Fi signal is too weak.
- Signal is distorted by external interference.
If, however, the laptop finds and catches only unprotected (non-passworded) networks, “cures” of blindness only when disconnecting other devices from the access point or shows other forms of selectivity, then the fault, as a rule, faulty or outdated network driver.
Enabling Wireless Internet on Windows 7
To activate it, you need to follow these steps:
- Click on the icon in the system tray. Go through the menu to the “Network Connection Control Center”.
- On the left side of the screen, select “Change adapter settings”. As a result, the list of connections will open.
The adapter is now in the active state.
The first thing to do is to physically turn on the Wi-Fi adapter. The procedure is slightly different for different models of laptops, but the meaning is the same: you need to find the hardware switch or use the function keys. Let’s look at a few examples:
- Some Lenovo models (e.g., T-61) have a small switch on the front left side of the case.
- On Asus laptops, the wireless module is turned on by the FnF2 shortcut.
- On some HP laptops the switch is located on the back or side panel.
We can go on and on about the options for enabling Wi-Fi, citing methods for MSI, Acer, Samsung and other brands. Even different series of the same manufacturer have different ways to activate the wireless module, so:
- Examine the laptop case for a hardware switch or a Wi-Fi power button.
- Study the keyboard. one of the keys of the row F1-F12 should be marked with a wireless connection icon. If you press it along with the Fn button, the adapter will turn on or off.
If you have a Sony Vaio laptop there may be no hardware key or Fn button on the keyboard. If this is the case, a special VAIO Smart Network utility is required for Wi-Fi connection, which can be found on the manufacturer’s official website.
How to turn on Wi-Fi on your laptop and connect to the network // Windows 11/10
Today, Wi-Fi networks have swarmed all major cities, routers are present in almost every apartment, where there is a computer or laptop. However, not always the connection of the laptop to the Internet is bright and easy (as you have understood, today’s article will be about this ☝).
In general, the first thing a laptop user should do is to check the Wi-Fi adapter, whether it is on, whether it works.
With this many people have all sorts of questions, especially if the power button suddenly does not appear on the body of the device (even worse, if in addition there is no function key on the keyboard).
In this short article I will consider how to check and turn on the Wi-Fi adapter, and then connect your laptop to the network. #x1f44c;
The hardware switches
Now let’s see how to enable the WI-FI adapter hardware. Some Asus models are equipped with a special switch that allows you to fully turn off this adapter. Its location on the laptop can be different, so you need to look at its documentation. The toggle switch should always be set to On. The second important point is a combination of keys, which also allows you to turn it off. It consists of a keyboard layout switch Fn and one of the function keys (it shows the Wi-Fi logo). By pressing them at the same time, you can turn off or on the wireless network card. Indicator of the status of this device is a corresponding LED. If it is on or flashing, then the adapter is active. Otherwise you will need to press the key combination again to activate it. Another important thing to consider is the availability of drivers. This will be described later in this article.
In some cases it is necessary to enable WI-FI on Asus laptop with the help of BIOS. Since this option can be located in completely different sections of the menu, you can not do without the manual here. In it we find this item. Then at boot or reboot your notebook, go to the basic settings. Then find the item you are interested in. It must necessarily be set to Enabled. If this is not available, change it using the appropriate keys.
Turn on WI-FI in Windows 7
Windows 7 WI-FI connection with a functioning module and correctly installed drivers should not cause any problems.
You only need to click on the appropriate icon at the bottom right of the screen, in the tray. Then select the desired access point and write the network security key or use the WPS function to connect to it. But sometimes this simple sequence of actions does not work. First you need to check the network drivers installed in the system. Here is the procedure:
- Open Start menu, then “Control Panel”.
- Launch “Device Manager”.
- Find the line “Network adapters” and expand to find the right one. WI-FI module name must contain the word “Wireless”. If the device is not on the list, you will need to install the appropriate driver. If it is there, but the icon has a yellow exclamation mark, then move on to the next item.
- Right-click on the line and click on “Engage. Also the problem may be that the device is turned off to save energy. To fix this, go to the adapter’s properties and open the “Power management” section. Uncheck the box that says “Turn off adapter to save power”.
If this method does not help you to connect to wireless networks, you can try to change the properties of the wireless connection. The instructions on how to enable Wi-Fi manually on Windows 7 are as follows:
- Launch the Control Panel.
- Click on “Network and Internet” and then select the first item.
- In the menu on the left, click on the marked item.
- Right-click on the current wireless connection and open its properties.
- Uncheck TCP/IPv6 and open TCP/IPv4 properties.
- Set the automatic obtaining of IP and DNS addresses, confirm the current settings.
- Now you can connect to a wireless access point. To do this, click on the WI-FI icon in the tray and select the desired network. If necessary, enter the security key.
After all these steps, you should be able to access the Internet.
Wi-Fi on a laptop doesn‘t work: why it doesn‘t connect to a Wi-Fi network. What it is possible to make?
Perhaps most of the questions I get about laptops are related to the configuration of the Wi-Fi network (or, more precisely, why is the Wi-Fi not working ☝).
This can happen for a variety of reasons, most often associated with the installation of new hardware, reinstalling Windows, changing some settings, etc.д.
In this article I want to touch on all of the most common reasons why a laptop can’t connect or see the Wi-Fi network.
Before you call in a technician to fix the problem (and spend money). I think you should at least try to figure it out on your own. run through the following problems, diagnose the cause, and fix it. #x1f44c;
Wi-Fi is turned on, but the laptop does not see the network or does not connect to it
Almost in 80% of cases (based on my personal experience) the reason for this behavior is the absence of the necessary drivers for Wi-Fi, which is the result of reinstalling Windows on the laptop.
After you have reinstalled Windows, there are five possible events and your actions:
- Everything is detected automatically and you are working on your notebook.
- You install individual drivers that are not detected, from the official site.
- You use driver-pack to automatically install drivers.
- Some devices are not detected, but that’s okay.
- All the drivers are taken from the manufacturer’s official website without exception.
In first four cases, Wi-Fi adapter may not work as it should, even if Device Manager shows it works fine. In the fourth case it is possible that there is no wireless device in the system at all (t.е. Windows doesn‘t know about it, although it is physically there). In all of these cases, the solution is to install drivers from the manufacturer’s website (here are the addresses where you can download official drivers for popular brands)
How to find out which Wi-Fi driver is installed on the computer
On any version of Windows, press the Win R keys on your keyboard and type the devmgmt command.msc, then click “OK”. Windows Device Manager opens.
Open “Network Adapters” and find your Wi-Fi adapter in the list. It usually has the words Wireless or Wi-Fi in its name. Right-click on it and select “Properties.
In the window that opens, open the “Driver” tab. Pay attention to the items “Driver supplier” and “Development date”. If the vendor is Microsoft, and the date is several years off from today. go to the official website of the laptop. How to download drivers from there is described in the link I gave above.
Update 2016: in Windows 10, the reverse is possible. you install the necessary drivers, and the system itself “updates” them to less capable. In this case, you can roll back the Wi-Fi driver in the Device Manager (or by downloading it from the official website of the laptop manufacturer), and then prohibit the automatic update of this driver.
Once drivers are installed, you may need to turn on your wireless network as described in the first part of the guide.
Additional reasons why your laptop may not connect to Wi-Fi or see the network
Besides the options suggested above, there could be other possible reasons for the Wi-Fi network problems. Very often the problem is due to the fact that the wireless network settings have been changed, less often it is due to the fact that you cannot use a certain channel or standard of a wireless network. Some of these problems have already been described on the site before.
In addition to the situations described in the above articles, there may be others worth trying in the router’s settings:
- Change the channel from “auto” to concrete, try different channels.
- Change the type and frequency of your wireless network.
- Make sure that Cyrillic symbols are not used for the password and SSID.
- Change the network region from USA.

Wi-Fi does not turn on after Windows 10 update
Two other options that, judging by reviews, work for some users whose Wi-Fi on their laptop stopped turning on after updating Windows 10, the first one:
- At the command prompt, as an administrator, type the command netcfg.s n
- If the answer you get on the command line is DNI_DNE, enter the following two commands and after they are executed, restart your computer
The second option is if you had some third-party VPN software installed before the upgrade, uninstall it, reboot your computer, check your Wi-Fi, and if it works, you can install the software again.
Perhaps all I can offer on the subject. I’ll think of something else, I’ll complete the instructions.
