Why doesn't my laptop connect to WiFi? Using a separate button that activates the module. Internet no access or limited in Windows

Today we will try to analyze a pressing issue - the loss of a Wi-Fi network. Almost everyone has encountered this situation and asked themselves the question of why the laptop does not connect to the Internet via a wireless connection.

There may be several reasons for the failure, as well as solutions to this situation.

We will discuss different solutions to this problem in detail in this article.

Let's say Wi-Fi is connected to the laptop, but there is no Internet. There may be several reasons for this problem:

Problems with the access point (the router is out of order, the provider is performing technical work);
Problems with the device (Wi-Fi on the device is faulty, the drivers have crashed).

Different devices display fault statuses differently. On a laptop, an exclamation mark may appear in the Wi-Fi network status bar, indicating a connection problem.

On Android devices, the Wi-Fi icon changes color from blue to gray.

Regardless of the type of warning, you should check the functionality of your Internet connection using a browser. If there is no Internet, an error will appear.

How to connect the Internet to a laptop via Wi-Fi

Connecting a PC occurs in several stages:

Now go to the browser to check:

Everything works, which means the connection was successful.

Operating system Windows 10

On computers with Windows OS, the connection is a little easier:

What to do if there is no network icon on the panel?

Sometimes there is a situation in which the Wi-Fi icon is missing. In this case, you need to do the following:

Open “Control Panel”;
Go to “Network and Internet” / “Network and Sharing Center”;
Go to “Change adapter settings”.

There will be several connections in the window that appears. You must select “Wireless Network” and right-click on it.

Select “Enable” from the drop-down menu. After this, the icon will appear on the bottom panel.

Lack of drivers

Another reason for the absence of an icon may be driver incompatibility or incorrect installation. This problem is quite rare and can be solved by reinstalling the drivers that come with the laptop. The process is automatic. After starting the disk, the system itself will offer to install the necessary drivers.

Error: "Windows could not connect to Wi-Fi"

The most common problem is with laptops running Windows 8 and 10. If your network absolutely refuses to work, try connecting to a different network. For example, from friends, or share the connection from a mobile device using modem mode. This method will help determine the malfunction.

If the connection is successful, you can diagnose a laptop malfunction. This means that the cause of the problem is in the router itself.

You should check the connection to the router from another device. If you successfully connect another device, you should check the IP addresses of the laptop. To do this, in “Changing adapter settings” you need to right-click on “Wireless Network” and select “Properties”.

The correctness of the connection can be determined by the packets sent and received. If one of these areas has a value equal to “0,” then there is an obvious conflict between the IP addresses or the devices themselves.

The solution to this problem is to switch the device to automatically receive IP addresses. In 99% of cases, the problem is resolved after applying the parameter.

But, if there is no connection on all devices, you should blame the router. First, you should try updating the device if there is a new firmware version. You can call the manufacturer's technical support. They will be happy to help you update your gadget.

If the update does not help, then you should contact the service center. The average lifespan of a router is about 5 years. After this period, it is recommended to replace the device.

Device incompatibility

Currently, this phenomenon is extremely rare, but still occurs. The reason for this is the manufacturer, who initially does not set the correct compatibility algorithm for various devices. There may be no connection on the PC, but the mobile phone will connect easily. The reason is the incompatibility of devices. Updating drivers or installing a patch that will allow you to use the device without problems will help eliminate the lack of Internet.

Drivers

But the problem with drivers is not uncommon. Outdated computer adapter drivers can create many connection problems. You can update drivers in several ways:

Using a helper program. Driver Pack Online is a popular program for Windows designed to solve driver problems. It automatically finds all the necessary drivers, downloads them and installs them at the user's request. The program interface is simple and intuitive. The program is absolutely free.
Using the Windows Update Assistant. It helps to automatically find and install updates. But it has some disadvantages:

Limited number of drivers;
The search takes a lot of time;
The system is extremely unstable;

Thanks to such assistants, the search process will be reduced to a minimum and will not require unnecessary actions from you.

Conclusion

Most users experience connection errors. For some, this problem occurs once, while others suffer on an ongoing basis due to incompatibility with the device and lack of updates. I hope that with the help of this article you will be able to solve the problem of why the Internet on your laptop disappeared via Wi-Fi.

Video instruction

If you still haven't found a solution to your problem, perhaps this video will be useful to you.

Problems with the Internet are always unpleasant. They can interfere with work or entertainment, or limit other online experiences. If we are talking about a cable connection, there may not be many possible causes for this problem.

The laptop detects an available Wi-Fi network, but does not connect

One fairly common network problem is when your computer sees a network available to connect to, but for one reason or another cannot connect to it. This problem may occur for one of the following reasons:

a problem with the hardware drivers on the laptop - for this reason, the connection may not work or may be interrupted immediately after a successful connection to the network;
communication interference - there should not be too many devices connected to Wi-Fi, and you should also make sure that nothing can create interference between your laptop and the router;
the password for connecting to this network was entered incorrectly - if you entered the security key incorrectly, the connection will not be completed;
network mismatch - if the connection settings on your computer and the network settings do not match, the connection will not succeed;
failure of the operating system - in case of some problems with the operating system, the connection will not be made correctly.

Solutions to problems with connecting to a wi-fi network

Let's look at the solution to each of the problems mentioned above one by one, and also study general recommendations for those who have encountered this problem in their system.

Error “Windows could not connect to Wi-Fi” and how to solve it

When you try to connect, you may see the message “Windows could not connect to the Wi-Fi network.” This error can have several causes. You can determine the source of the problem as follows:

Security key mismatch when connecting to a Wi-Fi network

A security key is a security code for your Wi-Fi network. The user sets it independently so that strangers cannot connect to the network. And if you encounter an error about entering the wrong password, then it is likely that it was indeed entered incorrectly. Do the following to be sure to correct the situation:

You should not tell your security key to strangers - this will lead to additional connections, which in turn will slow down your Internet speed.

Inconsistency between saved network parameters

After creating a new connection, you may often see an error with the text “The network settings saved on this computer do not meet the requirements of this network.” This problem often occurs after setting up the router yourself. To fix this situation, all you have to do is delete the connection and then create it again. This will update all settings and establish a connection again. This is done as follows:

In Windows 10, this problem is solved a little differently:

The problem may arise, for example, due to a careless change in the data in the connection settings.

Other ways that can help you connect

And now let's look at a few general solutions that can help you with various connection problems. In our case, when it is impossible to connect via Wi-Fi, these methods will also help.

Reboot the router

The simplest method, which is recommended by all providers first of all. Of course, this will not help with serious problems, but it can eliminate one-time connection problems. The best way to reboot is as follows:

Checking and installing network drivers

Updating network drivers is no more difficult than updating drivers for any other equipment. You can do this using the automatic driver download system as follows:

Press the Win+X key combination to open the quick access menu and select the “Device Manager” section there. Another way to get to this menu is to right-click on the Start icon.
Select the "Device Manager" section from the quick access menu
In Device Manager, find the Network Adapters section. Expand this tab and you will see your network devices. And then right-click on the available equipment. After the context menu opens, select the “Update drivers...” action. In order to determine whether a device needs to update its drivers, pay attention to its name and the presence or absence of an icon indicating the need to update drivers.
Open the "Network adapters" section and click "Update drivers" on the desired device
You will be asked for an update method. If you have an Internet connection (for example, using a cable, since a Wi-Fi connection is not available), then just click on the “Automatically search for updated drivers” button.
Select "Automatically search for updated drivers" if you have a network connection
Wait until the search, download and installation of drivers is completed.
Wait for the drivers to be searched on the network and installed.
If there is no network access, you must download the driver for your network adapter from another device and select “Browse for drivers on this computer.”
To search for drivers yourself, select “Search for drivers on this computer”
Specify the location of the folder with drivers for further installation.
Specify the location of the drivers on your computer and click on the “Next” button
After the installation is completed in one way or another, restart your computer.
Try connecting to the Wi-Fi network again to see if your problem is resolved.

If a simple update does not help, try completely uninstalling the driver and installing it again using the same method.

Resetting the router

If problems with the Internet do not go away and you still cannot connect to Wi-Fi, you should resort to a more radical way to fix this problem. Namely, reset the router settings and configure it from scratch. You should not do this if you are unsure of your own knowledge and attentiveness - you risk being left without access to the Internet. You can reset the router in the following way:

After performing the reset, the device will return to factory settings. Most likely, you will not have to configure anything manually after this and your Internet problems will already be resolved. But in case you still have to make the settings yourself, this is done as follows:

This will complete the setup of your router. Depending on the equipment model, some items may be named slightly differently, but the setup will occur in the same way.

Video: how to configure a router

If your laptop finds a Wi-Fi network available for connection, then the problem is not so bad. And after studying this article, you will surely be able to establish a stable connection. Use the Internet for work and entertainment, and most importantly, do not panic in case of problems. Because now you know how to fix them at any time.

Wifi is becoming more popular every day. It completely covered apartments, offices and public places. But often various problems arise with it. In this article we will talk about Why doesn't my laptop connect to the wifi network?.

If we talk about Why doesn't my laptop connect to wifi automatically?, then you need to consider the main problems. There are many reasons associated with the lack of connection to a wifi network. We will divide them into several types:

The laptop itself is malfunctioning.
Problems with the router.
Other problems with networks.

So, let's look at each of the points in more detail.

Laptop problems

Lack of network card drivers

To use wifi with a laptop you need special drivers. Usually they are present on the computer, but situations arise when the user decides to reinstall the operating system. In such cases, all drivers have to be downloaded again.

In order to check the driver you need to go to the device manager. If you do not find the “wireless adapter” item there, this means that you need to slightly update the system software. We put the laptop on the back side and look for the model number. Next, go to the manufacturer’s website and enter it. Download the driver wifi and it is automatically installed. But this method is not suitable for ordinary users. Why not fits? There is an easier way. In the address bar of the browser we write “drp” or “driver booster”. These are special driver packs that will automatically update your system. They are downloaded absolutely free from the manufacturer’s website. We install them and launch them. Next, we look for a button to start the update. Click and wait until all drivers are updated.

Don't forget to restart your computer after completing the operations.

The Wi-Fi network adapter is turned off on the laptop

One of the reasons for the lack of wifi connections may be a disabled adapter. It is controlled by a special light bulb that looks like an antenna. You can find it on the front panel of the laptop. If the light is on, then the problem is not there.

If the wireless adapter is turned off, you need to start it. To do this, press the “fn” + “*” keys. Instead of *, you must select the button on which the antenna is drawn. It is different for all devices. After this, the light should light up. If this does not happen, then return to the driver update item.

WLAN automatic configuration service does not work

This problem occurs quite rarely, but we will look at it. First you need to go to “Run”. To do this, press the key combination win+r. A small window appeared. Enter the line “services.msc” into it. After this, the services menu opens. We start the WLAN automatic configuration service. To do this, right-click on it and click on the “run” line.

After this procedure, wifi should work.

Problems related to the router

Wireless connection is turned off

First you need to make sure your router is turned on and working. After this, we check whether the wireless connection is turned on. If it is turned off, then perform the following steps:

Launch the browser.
Enter in address bar ip of your router. You can find it on the back of the device.
When logging in, provide your username and password. The standard ones are admin/admin.
Go to settings and turn on the wireless connection.
If necessary, change the ssid and key for your wifi.

After this, your device should detect Wi-Fi.

Checking the mac address

There are times when all the data is entered correctly and the laptop sees the network, but cannot connect. If you encounter this, then you need to check the MAC address due to which access for some devices limited.

We go into the settings of your router as we did in the previous paragraph. Find the “restriction mode” parameter. It should be disabled by default. It is recommended not to use it on your home network. But if you still need it, then check the list of blocked devices. If the mac address of your device is indicated there, then remove it from the list.

The Internet itself does not work

It is necessary to understand that wi-fi and Internet- different processes. There are times when on a laptop says limited access connections. In such cases, you need to go to your computer and check the Internet on it. If it doesn't work, then you won't be able to distribute it.

Also limited network access may occur immediately when starting the laptop. Don't panic, just wait a little.

Remember that if the Internet connected, that doesn't mean it works.

External barriers

If you connected to the Internet, but it suddenly stopped working, then you should understand that wifi is very dependent on external factors. Walls, furniture, and household appliances can greatly weaken the signal. In such situations, you need to move the laptop closer to the router.

If you do not want to keep the devices at close range, then you need to purchase a repeater. Install and configure. After that connect to him. This way you will greatly increase the coverage area of your wifi signal.

Let's sum it up

Reasons why it doesn't work wifi on laptop a lot of. We have already told you about most of them. But there are times when wifi does not work due to a malfunction of the router or laptop itself. Try rebooting the devices, if this does not help, contact the service center.

A fairly common problem today is that WiFi on a laptop does not connect. Typically, the lack of data transmission via the wireless interface is due to incorrect software settings. The first item on this list is accidentally turning off 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 operation of the adapter) and, if necessary, reinstall it. At the last stage, we check the network settings. Phased

Completing all these steps in most cases allows you to eliminate this problem when WiFi on a laptop does not connect.

Turn on the adapter

Most modern mobile PCs have an enhanced function keyboard on their keyboard. It can be activated by pressing a special key - “Fn”. In this case, the standard set of characters stops working, and you can only use the additional one. It consists of 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 “Fn” immediately and without releasing its key with the antenna and waves extending to the sides, an inversion of the current state of the adapter will occur. If it was turned on, it will turn off. To return it to its original state, you need to press the previously given key combination again. It is important to pay attention to the WiFi LED indicator. If it is turned off, then it will have to turn on, then the adapter will be in the on state, and it will be possible.

The second option to turn off the wireless network card is using the toggle switch. Its operating principle is similar to that previously given, with the same combination on the keyboard. When moving it from one position to another, the picture will be similar - WiFi on the laptop does not connect and the corresponding indicator does not light up. To turn on the adapter, you need to return it to its original state. Depending on model

mobile PC, both the first and second shutdown methods can be used. In premium models, a combination of these is possible.

Checking the driver

Next, you need to check that the network adapter driver is installed correctly. Its failure may result in the laptop not connecting to WiFi. First you need to find the disk that comes with the device. If it is not there, then download the installer from the official manufacturer’s website on the Internet. Then go to Start\Panel. Here we open the “Network adapters” item and look at the wireless card. If there are no icons opposite it, then we proceed to the next stage. Select our wireless adapter by left clicking the mouse and pressing “Del”. This removes existing drivers. Then we start installing new ones from the disk or downloaded file. After this, it is recommended to reboot the system. If this does not solve the problem, move on to the next step.

Checking network settings

At the final stage, we check the connection settings. To do this we open

double-click the left mouse button “Current connections” (shortcut with increasing sticks on the right side. In the list that opens, select the properties of the required one. 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 your PC for viruses. After completing all three stages, this problem when WiFi does not connect on a laptop is solved in most cases.

Conclusion

If all the operations outlined in the article have been completed, but 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 a problem in which the laptop has stopped connecting to WiFi, and wireless transmission is restored.
