Why does the laptop not see the wifi network. The laptop does not see WiFi. Solution. Technical reasons for the lack of Wi-Fi due to the laptop

Unfortunately, many of us have faced the problem when the laptop stops finding the wireless network, which creates a noticeable inconvenience. Considering that the laptop can be used outside the home, the user may be left without the Internet at all. There can be a lot of reasons for this little pleasant moment. But, as a rule, the problem is technical, or in the wrong work. software... To understand how to cope with the problem, let's look at it in more detail.

In order to understand the causes of the problem and understand why the laptop does not find WiFi router or home WiFi network, you need to know what WiFi is and understand how this system wireless communication arranged.

WiFi is the same the local network, only without the need for a cable. The connection to the network occurs through a signal that is transmitted through radio waves. This system has gained popularity not so long ago. A dozen years ago, no one knew about it, and the signal distance was much less. To be precise, the signal can be sent over a distance of 100 km.

In addition, WiFi is a registered trademark that is actively developing. In 2014, the data transfer rate over WiFi should increase to several Gbps.

Simply put, now this way network connectivity is very popular. Almost every laptop has a built-in sensor that allows you to use a wireless network. At bus stops, cafes or any other public places, the owners install free access points, which increases the level of comfort of the establishment or public place.

As mentioned above, the main reasons can be roughly divided into technical and software. In the case of technical ones, the owner of a laptop will most likely have to contact a service center and spend money on repairing it. V best case, deal with the reason for the poor operation of the router.

WiFi on laptop and router

It's worth starting with the very basics, which can be forgotten due to haste or inattention.

Make sure the receiving antenna is turned on. If the WiFi button does not work, then the problem is obvious. Not all laptop models have this switch, but some do. Most often it looks like a latch rather than a button. In other words, it depends on the manufacturer. With a switch, there can be a signature or a picture of the antenna, which stands for WiFi.

If there is no such button on the laptop model, then you need to pay attention to the lower panel of the operating system, to the icon next to the time. The image should show if the wireless connection is active at the moment.

It is possible that this icon is not on the panel next to the time.

To check activity without using this icon, you need to:

Checking available networks

The next thing to do is check the available networks. Perhaps the router simply does not reach the laptop's antenna and for this reason it is impossible to connect to the network.

This requires:

click on the network icon in the lower right corner, on the bottom panel, next to the time.
Select the "Connect to the network" item and select the desired access point. Most likely, there will be more than one access point, since you can see neighboring or some other routers. But, in most cases, a password is put on the access point, thus protecting it from unauthorized users.

The laptop does not see the WiFi network: the main reasons

Why can't my laptop see WiFi network? Perhaps the solution to the problem is right in front of you and only takes five seconds. But there are also more severe cases. Let's consider the most common options.

Router

It is worth making sure that the router is turned on. Its operation can be easily identified by the indicator lights. After connecting, look at the corresponding icons in the instructions for the router and determine if the wireless connection is active.

If the router does not respond at all, then the problem is purely technical. In this situation, you should look for a problem in the wires, power supply, or carry the router for repair. As a rule, it is easier to replace a router with a new one than to give it to service centers for inspection.

Drivers

As you know, any hardware requires software that guarantees stable operation. If the laptop does not detect WiFi, then it is worth checking the drivers. Even if they are installed, it is recommended to update them.

You can check the drivers through the control panel. In the section "Device Manager" there is a line "network adapters", which should contain the name of the router, if the problem is in the drivers. Click on right click mouse on it and see the driver version. Compare it with the current version, which can be found on the Internet.

If the version is outdated, then download the new one and install. It is best to download from official sources. Hardware drivers are distributed by developers for free, and you shouldn't risk the health of your operating system in vain.

Signal distance

If, after searching for a network, the answer appears: “No available connections"- think about the signal. In apartments, this option is not very relevant, since modern routers have a strong signal and spread it far enough. But in private homes or other places where the distance can be quite large, the signal may simply not reach the laptop. Therefore, do not be surprised if the Internet suddenly disappeared when you were walking around the house or yard.

Mac address

There are situations when it was possible to connect, but the router does not see the Internet through my WiFi or has stopped seeing. When using the services of some providers, the user cannot just change the network adapter, as the Mac address changes.

The Mac address is written on each router and the user only needs to call the operator to new address bind to replace the old one. You may be asked to dictate it in full, or to clarify only the last few values of the entire number.

Antivirus or third-party programs

Third party programs installed on a laptop may conflict with drivers or interfere with the correct establishment of an Internet connection, which often happens when the device sees wifi but does not connect. In addition, sometimes antivirus software interferes with creating a connection. If possible, it is better to try first to connect the Internet without a router. If all is well, then the programs are not to blame.

In addition to the above, there can be a lot of reasons. Basically, a variety of reasons are due to malfunctions in the operating system. Therefore, if all else fails, try reinstalling your operating system. Perhaps all the problems come from here.

Laptop does not see WIFI network on windows7 / on windows 8 / on windowsXP

For those who are wondering why the laptop does not see wifi windows 7, first of all, you need to try manually turning on the wireless network.

This requires:

In windows 8, activity is checked through the "PC Settings" item. Next, you need to select the line "wireless" and move the slider on the right side of the menu to the "On" state.

When using Windows XP, the wireless network does not require manual activation and, as a rule, is connected like windows 7. It is enough to activate it via the control panel or via the wireless icon via the bottom panel of the system.

How to set up a wireless network

For a comfortable use of the network, some users resort to settings. Usually enough standard settings, but if you wish, you can delve into your personal account. It is through Personal Area the parameters are changed.

The login and password are indicated by the manufacturers of the router, and you can find these data in the instructions. The address is also indicated there, which will lead you to your personal account. It is best to replace the standard data so that no one can use it.

All other settings are made on the laptop itself, and they are installed using the Network Control Center.

WiFi without internet due to windows

There are rare cases when the operating system itself does not want to detect a wireless connection and shows that there is no external network at all. This option can be used when using non-licensed operating systems. Some people prefer to use amateur assemblies, which do not load the system so much and allow you to squeeze more out of iron.

Another reason could be "blockage" of the system. System folders, over time, clogged unnecessary files and if you do not defragment, then the processor will be loaded more and more. Antiviruses also cannot keep a laptop clean forever.

In any case, all problems with the OS are solved by a simple reinstallation. After reinstalling windows, everything should work. Thus, the solution to the problem lies only in the operability of the router, WiFi enabled on the laptop, or in the presence of the necessary software. Subject to these points, WiFi will not present difficulties and will delight the user stable work.

The computer does not see the Wi-Fi network

WiFi wireless technology is widely used all over the world. Everyone knows about it, and there are practically no people left who do not use it. Connecting to an access point is extremely simple and does not require any knowledge. However, everything is not always so smooth. Quite often, there are cases when the computer does not see available WiFi connections.

But before proceeding directly to troubleshooting, you should delve a little deeper into the principle of operation of this technology. The fact is that to connect to a WiFi network, you need a router that acts as an access point. This means that if there is no signal, the first thing to check is the access point.

Why does my computer not see available WiFi networks?

If the router is turned on and working, but the computer still does not see the Wi-Fi network, then you should go to the system settings. There can be many reasons for this error:

Drivers are not installed for network equipment.
Hardware error.
Disabled wireless network connection.
Defective WiFi module.

In addition, there are other problems. However, it is simply impossible to describe everything. Therefore, we will analyze the most common connection problems.

Checking the driver for network equipment

What if the computer does not see the WiFi network?

The first thing to look out for is the driver. This is special software that controls the operation of a particular equipment. Thus, if the driver for the network adapter is missing or does not work correctly, then, accordingly, the WiFi module itself will not be able to work normally.

You can check this in the device manager. Click on the "My Computer" shortcut (you can find it in the file manager or in the "Start" menu) with the right mouse button and select "Properties". In the window that appears in the left menu, you need to find and open the item "Device Manager". Here we see all the devices that are connected to the laptop. Among them you need to find network equipment. How to set up correctly wireless WiFi read the adapter here.

Open the branch with network adapters. The absence of such a branch indicates that the drivers for the WiFi adapter are not installed on the computer at all. If the device manager displays network devices, then you should check if the Exclamation point on any of them. If there is such an icon, then this also indicates the absence or incorrect operation of the driver.

In any case, this is solved by a simple reinstallation of the software, which can be downloaded from the manufacturer's official website. Or, if a disc was included with the laptop, then everything that is needed can be installed from it. The WiFi adapter in Device Manager is usually named Wireless Network Adapter. The driver is main reason over which the computer does not see the wireless WiFi network. If the drivers are in order, but the problem is not fixed, then go ahead.

Checking Wireless Status

The next reason why the computer does not see wireless networks WiFi is a disconnected connection. How can I check this? First, you need to open the Network Control Center. On different operating systems ah it is done in different ways. For example, on windows8, you can simply right-click on the network icon in the tray and select "Network Control Center."

You can also open the service as follows. Press the key combination Win + R and write control panel in the window that appears. Presses "Enter". Thus, we launched the control panel. Now we follow this path - Network and Internet general access... It should be noted that this service launch option is suitable for everyone windows versions... In the window that appears, we are interested in the item "Change adapter parameters". It's in the left menu.

In the window that appears, we see all the connections available on the computer. We find "Wireless network" (if windows7 is used, then "Wireless network connection"). If the label is gray, it means that the connection is disabled. To enable it, click on it with the right mouse button and select “Enable”.

After that, the system will turn on the connection and start searching for available networks. In some cases, if the computer still does not see the Wi-Fi network, then after the procedure done, you will need to turn on the module on the keyboard using the Fn key combination + the adapter power button.

Performing diagnostics

If you have followed all the above options, but the computer still does not see the Wi-Fi network, then you can resort to system diagnostics. To do this, open the Network Control Center and go to the "Change adapter settings" item.

Here we find the shortcut for the wireless connection and click on it with the right mouse button. In the window that appears, select "Diagnostics". After that, the computer will start troubleshooting and fixing them on its own. After that, he will display a message about the detection of problems (if any) or tell you what to do next.

Hardware error

What does a hardware error mean? This is a problem directly in the board itself (network card). In other words, if the computer does not see the wireless WiFi adapter, then this indicates that it is not working. This can happen for two reasons:

The laptop does not see the wifi network: what to do? | Your setevok

The problem of incorrect display or complete absence of available wifi networks is quite common and affects not only laptops, but also stationary computers, tablets, smartphones, etc.

Possible reasons there is a lot of the fact that the Internet on a laptop via wif does not work well. In order to choose the right option for solving this problem, you need to evaluate which "scenario" your situation refers to: the laptop has stopped seeing wifi networks altogether (ie, a complete "ignore" of wireless connections), or the laptop does not see wifi from any one point access, easily identifying other sources of the Wi-Fi signal.

Why doesn't wifi work on my laptop?

To begin with, it is worth analyzing the most common scenario - complete "ignoring" by the computer of all wireless networks. Those. Are you sure that:

- the router normally distributes a signal and the access point is "open" for connection;
- there are other available wifi networks nearby;
- other devices (for example, cellular telephone) detect active sources of wireless signal without any problems.

But at the same time, your laptop does not find a single wifi network and does not connect to the Internet - i.e. Wi-fi on the laptop stopped working altogether.

1. To solve this problem, first of all, it is worth checking if the "wireless network adapter" is enabled at all. For this:

- open the "Device Manager", in the "device tree" select " Network adapters»;
- in the list that opens, there should be an adapter for your wireless network (the name of which depends on the model of the device and you can clarify this parameter in the documentation for the laptop);

- there should not be a triangular yellow icon with an exclamation mark next to the adapter name - it means that the wireless network adapter is disabled, or the network driver installed and used by the laptop does not work correctly;
- to turn on the Wi-Fi adapter on the laptop, right-click on it and click "Enable / Connect";
- if the driver does not work correctly - download and install current version programs for your laptop. Or remove the device through the "Device Manager" (pre-download required driver- for safety reasons) and restart the PC - the adapter should appear automatically.

In addition, you can check the adapter through the "Control Panel" - "Network and Sharing Center": if the adapter is enabled, then there should be a section either "Wireless network adapter" or "Wireless adapter".

2. Perhaps the laptop does not see the Wi-Fi due to the fact that the network is disabled by a keyboard shortcut or a special switch on the case: for laptop owners given reason most relevant.

It is worth paying attention to the combination of keys "FN + F2" / "FN + F3" / "FN + F9" / "FN + F12" (depending on the laptop model) - this combination enables / disables the network and is intended mainly for those who often flies (accordingly, this mode is called "On the plane" - a similar function is available for most modern smartphones and tablets).

3. If the laptop stopped seeing wifi after the device was disassembled (to clean the upgrade from dust), then it may have been physically disconnected during the parsing wireless module or the integrity of the connection wires is broken. In this case, the solution to the problem, accordingly, will be to connect the adapter (and in the event of a physical malfunction, replace it with a working module).

Why does the laptop not see wifi, but other devices see the router?

Now let's consider the situation when the laptop selectively does not see the "wifi" network. It is worth noting that most of the problems with wireless networks can be resolved by updating your network drivers.

So, there is a certain network that works and is displayed on other devices, but the laptop with great persistence does not want to see it. You can do the following:

First of all, try changing the encryption method in the wifi security settings

and modify with the parameter "Channel";

Try to change the name of the network - try to avoid complex symbols in the name.

Also, the reason that the laptop does not see the wifi network on windows 7 / windows 10 may be the infection of the computer with viruses and problems with the hardware.

This applies directly to the computer, however, the culprit for the fact that the laptop does not see the Wi-Fi router may be the source of the wireless signal itself.

- check the relevance of the installed firmware on the router: if the firmware is outdated, then, accordingly, update it to the most recent version;
- reset the router configuration to the default value (factory settings) and reconfigure the router;
- in some cases, installing more old version firmware, with network configuration and subsequent firmware update.

Thus, the most relevant and effective solution The problem "the laptop is not looking for Wi-Fi" is to check the functionality of the wifi module and install the latest drivers.

To avoid this problem, you should regularly update your computer software (manually or using special programs).

The computer does not detect a wireless Wi-Fi network

There are times when Wi-Fi stops being available on the computer. Why this happens and what to do in each specific case will be discussed in this article.

The problem can be of two types: the computer does not see at all Wi-Fi networks or only your access point is not in the list of available neighbor networks. In the first case, the problem is most likely in the wi-fi device, in the second - in the computer on which the network disappeared.

First steps

What should be done first? You can reboot the router or computer on which the network has gone missing. Make sure to enter the correct password and not enable Caps Lock. If the passphrase is correct, but the computer does not connect, then you need to look for other reasons.

If the computer does not see any access points at all and / or has stopped seeing them: you need to check if the Wi-Fi adapter is active. You need to do this: on the computer keyboard, press the key combination "Fn + F3" (depending on the model and manufacturer, there may be a combination of "Fn + F2" or "Fn + F5"). The keyboard drivers must be installed for the keyboard shortcuts to work. On older models, the ability to see Wi-Fi is sometimes turned on with a separate button.

Network problems

If you have installed the drivers for the keyboard, turned on the Wi-Fi module, but there is still no Internet, then open the "Control Panel". Select "Internet Networks" and in "Sharing Control" select "Changes to adapter settings." Here you will see a list of all adapters. Click on the "Wireless network" item. If the gray icon and the inscription "Disabled", then there is no Wi-Fi icon in the system tray, which is why nothing works. In this case, you need to enable: call with the right button context menu and make the choice "Enable". The wireless network becomes active. In case of an error, the launch of "Diagnostics windows networking". The system itself can find and fix errors.

If after that the computer does not detect an available network, then reinstall the drivers for the wireless network adapter. Open "Device Manager", click on "Network adapters", find desired device... You need to uninstall and reinstall the driver. Drivers can be taken on the official page of your computer manufacturer or found a CD with a working driver bundled with your computer. After installing the driver, you need to turn on the Wi-Fi module and see the work - if everything was activated, we figured out why the network disappeared.

Sometimes it happens that the laptop does not see the wireless network after being repaired or after cleaning. The masters can turn off the antennas. Then you need to disassemble the laptop case and connect them or seek help from specialists.

Router problems

If the problem is that the computer does not see only your router, but sees others, then you need to do the following steps. Find router settings and check Wi-Fi operation adapter. To do this, open a browser and enter http://192.168.1.1 or http://192.168.0.1 in the address bar. If it did not work out, the data on the ip-address and authorization in order to enter the page can be taken from the sticker attached to back side the case of the router or on the manufacturer's website. On the router page, you need to find "Advanced settings", the "Wi-Fi" tab and network settings". You need to set the "Enable wireless connection" flag. If the flag is on, but the problem remains for some reason, then last way- this is a change of the channel on which the router is running. In order not to change the channel blindly, you can use the program "inSSIDer for Home", which analyzes the frequency range of the channel. From 1 to 11 channels - the American standard for Wi-Fi operation, most devices can do work on these channels. Available from 11 to 13. When changing the settings, do not forget to click "Save".

You can try to remove encryption, the setting is called "Authentication Method", change to "Open System". The problem might be the length of the key ("WPA Preshared Key"). If it is more than 20 characters, then the router will stop working with such a long key. Most likely, the key can be no more than 12-13 characters. You can also update the firmware right there: "Administration" section, "Update firmware" tab.

Software

Why are there still difficulties? The problem might be in the software. If "System Restore" is enabled in your windows, then restore points will be shown in the log when installing programs. You can return the operating system to the day the network was up and let it see connections again. You need to select a state, click "Next", follow the instructions. Wi-Fi network can often disappear when updating the OS, so sometimes you have to reinstall programs after updating, including for a wireless connection, and then the computer again sees what it needs.

Adapter malfunction

If all else fails and the computer still does not see the available networks, then there is a possibility that the Wi-Fi adapter could fail: it may burn out during operation, it needs good cooling. If it burns out, it will not be displayed in the "Device Manager", this problem will be displayed in the "Windows Diagnostics". It will need to be repaired or changed.

So, we have considered the most basic sources of problems when a computer fails with wi-fi. Remember that any problem can be fixed if you know its causes.

InstComputer.ru

The computer does not see the desired wi-fi point.

So, a couple of months ago I ran into one common household problem. A laptop (windows 7) sees many different wi-fi points, but does not see the desired wi-fi point (the one to which it needs to connect), and all other computers have perfectly established a connection and have been downloading porn from the Internet for a long time.

Googling on the Internet, I found a very trivial solution: I changed the channel of the Wi-fi point (in the settings of the access point).

I assume this is because in recent times wifi hotspot is in almost every apartment, and many of them have a self-determination of the range. It works as follows: the point turns on and scans everything around, determines the occupied channels and chooses the one that is not busy, but due to the fact that your computer is far from it, it may well catch the signal that your point did not catch. You turn on your computer, it also scans everything around and is the first to pick up a signal from the point that your point overlooked. And as a result, the computer does not see the desired point - it works with another on one channel.

Quite recently I again encountered this problem, but this time I did not have access to the point, but I wanted to go to the Internet very much (from the entertainment at home there was only persimmon and the book "Western Philosophy from the Beginnings to the Present Day"). So I decided to try setting up wi-fi from the computer side.

In the adapter settings, I changed the "Scan the allowable interval to the minimum value" parameter and everything worked (control panel → Network and Sharing Center → Network and Sharing Management → Wireless Network Management → Adapter Properties → Configure → Advanced).

This parameter is responsible for the interval of scanning the air to search for new wi-fi connections... In my case, up to this point, the connection to the point has already been established, the "Connect automatically if the network is within range" checkbox is selected in the settings (control panel → Network and Sharing Center → Network and Sharing Management → Wireless Networks Management (Properties right-click on the connection you need)). Accordingly, scanning the air every 20 seconds gives more chances that the computer will see the desired point and immediately establish a connection with it. This is what happened.

And a little about other options:

Transmit buffer, Receive buffer. Meaning this parameter allows you to specify the size of the buffer that stores data packets received from the network. On the Internet, in various forums, it is advised to set these values to the maximum, unless of course you have weak computer(in this case, I would advise you to buy a new one).

Preamble 802.11b (Preamble 802.11b). A sequence of binary bits that help synchronize receivers and prepare the reception of transmitted data. I am connecting to an access point with an 802.11n radio type, so I set this value to LongOnly. If you have any problems in this mode, then set the default value.

Network address(Networkadress). The MAC address of the configured software interface. Manufacturers themselves set this value unique, but if you are hiding from someone, you can change it.

And further. On the "Power Management" tab, I unchecked "Allow this device to be turned off to save energy", anyway, the battery on the laptop has long since died.

Surely everyone has come across a situation where the laptop does not connect to the WiFi network. What to do in this case? The first step is to identify the root of the problem. Reasons why it doesn't work WiFi connection on a laptop, set. Let's consider the most common of them and offer a solution for each.

If there is no WiFi adapter in the device manager, but in network connections there is no wireless connection, then this indicates that the network is simply not configured. To fix this, you first need to test the adapter's functionality. Make sure it is functional and has drivers installed:

The device does not see the network

One of the most common problems when connecting to a home network is that the laptop cannot see WiFi. The reason why the computer does not see the network is that the module on the PC is turned off, which is responsible for wireless connections... To fix the problem, you just need to turn on wi-fi on your device. To do this, click on the "Network" icon, which is pinned to the taskbar. After that, click on the Wi-Fi button.

If there is no such icon on the taskbar, then you will have to activate Wi-Fi through the "Options" menu. Use the Win + I keyset. This will launch the Options window. After that, select the item called "Network and Internet". In the WiFi tab, move the switch to the active position.

If the above method did not help, and the wireless network is still deactivated, then try turning on the wi-fi using the hardware method. The fact is that almost every laptop has a special "tool" that allows you to turn wireless connections on and off. It can be a special key combination or a separate switch directly on the body.

First, take a close look at your laptop. Find the switch. It looks like this.

If your device does not have a switch for wireless networks, then you need to use a special keyboard shortcut. The combination depends on the laptop model. Here are laptop keyboard shortcuts from the most popular manufacturers:

ASUS, Dell and Gigabyte - Fn + F2
Acer - Fn + F3
HP - Fn + F12
Fujitsu - Fn + F5

If the above combinations are not suitable for your laptop model, then try experimenting. Use different combinations of Fn + key from F1 to F12.

If your laptop sees other networks, but at the same time home connection it still does not find it, you need to restart your laptop and router. Then try changing the router channel. This can be done in the settings of the router. If your router still fails, then this indicates a hardware failure. Try taking your device to a service center.

Can't connect network

The list of the most common problems also includes the error when the laptop sees Wi-Fi, but it cannot connect to this network. There are several solutions to this problem. Let's consider them in more detail:

No Internet

The laptop is connected to the network, but there is still no Internet, and there is a yellow sign next to the "Network" icon? Or a notification appears on the PC when unidentified network without internet access? There are many reasons why the Internet does not work. Therefore, if you are faced with the above situation, then try to use the methods below one by one:

Reboot your laptop and router.
If WiFi disappeared on a laptop, and you are connected to the Internet via a cable, then check it. Perhaps he moved away or was damaged. If possible, replace the cable.
Check if the internet is paid. Perhaps you just forgot to pay for the provider's services.
Try changing the channel in your router settings (this solution can also help if WiFi on your laptop is intermittently disconnected).

If none of the above methods helped, then try setting static IP and DNS. For this you need:

Other errors

There are several more mistakes that confuse inexperienced users. For example, "Security key mismatch." This problem occurs if you entered an incorrect password. Try "Forget" the network, and then reconnect to wi-fi again. The router will ask for a password. Enter the key again (to make sure that the entered cipher is correct, uncheck the "Hide characters" checkbox).

Sometimes the computer swears that the connection settings that were saved on the PC do not meet the network requirements. Then just remove the Wi-Fi network and then reconnect to the router.

If the Internet catches, but it is slow, then you need to get closer to the router. The signal may be too weak due to the distance between you and the router. A bad connection can occur if two routers are working nearby. The solution to the problem is to disconnect one of the routers. If the signal is jammed by a neighbor's router, whose operation, for obvious reasons, cannot be influenced, then simply change the channel of your Wi-Fi.

Wi-fi - very convenient way internet connection. But there are situations when the laptop does not see the home network and there are no available connections. This is due to a number of unrelated issues. Why does my laptop not see the wifi network? Let's take a closer look at this issue.

Checking the operation of the router

What to do if the laptop does not see wifi? Before proceeding with troubleshooting the device, let's check the home network for operability. This is necessary to understand the cause of the malfunction.

Let's talk about a router. Sometimes, network problems are caused by this hardware freezing. If you see that the lights on it are blinking in a non-standard mode, then you need to fix it. To do this, unplug the router from the outlet, wait a few minutes and restart it. If there were no serious problems or breakdowns, then this will solve the problem. The laptop will then be able to connect to the network.

If the router hangs, this does not mean that it is not working.

This is the most incomprehensible problem of all existing in it. In any case, if there is no connection, it must be rebooted.

If you live in an area with unstable power lines, the router may also be affected. Its settings may be reset due to a constant voltage change, and it will stop distributing wi-fi. In such cases, you need to go to the device's web interface. To do this, launch the browser and enter into address bar ip, which is listed on the back of the router. The password and login are indicated there.

Checking the laptop's performance

If checking the router did not show any malfunctions, then you need to check the laptop itself. First of all, we will investigate the operation of network equipment. All modern laptop models have light bulbs that are located below the keyboard. We need to find the one that has an antenna sign or something else related to the wireless network. If such a light is off, then press the "fn" button (available in every laptop) + f8 or another key that suits your model. If it is on, then nothing needs to be done.

We also check the connection settings themselves. The name of the network, if it is not available for all devices, and the password for it must be correctly spelled out.

Before you panic, you just need to restart your laptop. In some cases, this will help.

More reasons why the laptop does not see wifi

If laptop does not see wifi network, then, among others, there are obvious points that we forget about. So, your device may not see the wifi network for simple reasons. Let's consider them and answer the question of what to do with them:

Disabled router. We turn it on and the problem should be solved.
If you are far from the router, then you need to come closer to it or set up a wifi repeater.
If the router hangs, then just reboot it.
The wifi adapter on the laptop is turned off. We turn it on, and a special light should light up.

All these problems are solved very quickly and practically do not require special knowledge... Now let's move on to more complex reasons why the laptop does not see the Wi-Fi network:

Unconfigured router. Exists optimal settings for each of the models of this device. If you can't set it up yourself, then you should contact your provider, who will do it with a guarantee and as efficiently as possible.
If the wifi network does not find every device. What to do? In such cases, you need to go into the settings of the router and change the "visibility" item.
Broken wifi receiver. A laptop is a technically complex device that cannot be disassembled by yourself. If your home wifi receiver breaks down, then you cannot do without the help of professionals. Replacing the receiver can cost you a lot.
Lack of drivers. This usually happens after reinstalling the operating system. To solve this problem, you need to go to the website of your device manufacturer, where you will find all the necessary drivers. You can also download driver packs that will update ALL drivers for your laptop. If this is not the reason, then such updates will never damage your device.
Viruses and other malicious software. They can block wifi networks and other ways of connecting to the Internet. You can get rid of them with the help antivirus software such as Kaspersky Anti-Virus, avira or microsoft security essentials. In some cases the best option- reinstalling the operating system, because from a large number of viruses that have accumulated long time, it is very difficult to get rid of.
Windows related issues. They arise mainly due to pirated copies and incomprehensible assemblies found on the Internet. You must use licensed software.
Invalid MAC address. It is unique to each device and is located on the back of the router. But some internet providers change it. If you don't know new MAC address, then call your ISP. He will tell you how to use it to normalize access to Wi-Fi.

What to do about the above problems? There is a small solution for each of them, but if you are not sure in your abilities to make them, then it is better to contact a professional.

Hello dear friends. As you probably already understood from the title, today I decided to touch on a very serious and painful topic, and try to figure out what to do when Wi-Fi does not work on a laptop or netbook and how to connect a laptop to a Wi-Fi router. By the way, it can be not only a laptop, or a netbook, it can also be an ordinary one stationary computer with Wi-Fi receiver. There have been a lot of similar questions lately, mainly to the article.

Now we will try to figure out step by step what and why problems may appear when connecting a laptop to wireless wifi networks. We will also try to find a solution to this very popular and unpleasant problem with connecting to Wi-Fi, or rather a failed connection.

Most often, problems arise when it is not possible to turn on the Wi-Fi module itself on a laptop. And when Wi-Fi is turned on, the laptop finds all available networks, but when it tries to connect, it writes. We need to check whether the drivers are installed on the Wi-Fi adapter, whether Wi-Fi is enabled on the laptop, etc. Now we are going to do this.

I noticed that most often problems with connecting to Wi-Fi are found in Windows 7. It is on this OS that the network without access to the Internet error very often appears, I wrote how to solve this problem in the article, the link to which is above. In fact, as practice shows, there can be a lot of reasons for this problem. And if there are many reasons, then there are many ways in which you can force a laptop to connect to a Wi-Fi router.

But it is not always the laptop, netbook, etc. that are to blame. There may be a problem in the access point, that is, in the Wi-Fi router. And the first thing we need to do when there is a problem with connecting to Wi-Fi is to determine what is the reason, in a laptop, or in a Wi-Fi router. Now I will consider the problem with connecting to my own router. Because if you are unable to establish a connection with someone else's Wi-Fi, then all claims to your neighbor, it is most likely that he has a problem :).

Who is to blame, laptop or Wi-Fi router?

As I wrote above, you first need to find the culprit. Before making any settings on a laptop, or a Wi-Fi router, you need to understand what the problem is, which is why it is impossible to connect the laptop to Wi-Fi. You can just set it up so that you have to do it and set everything up again. Most The best way to determine in which device the problem is hiding, it is to try to connect another device to the router, for example, another laptop, tablet, or phone. And a laptop that has problems connecting to Wi-Fi, you need to try connecting to a different wireless network.

I think that you understand my idea. If other devices are connected to your router (best with a similar operating system) will connect without problems, then the problem is in the laptop. Read this article further, now we will try to solve it.

Well, if problems when connecting to your network arise on other devices, and the “problem” laptop connects to other networks without problems, then the problem is in the setup. Wi-Fi router... See the article on, it might come in handy.

I will show on the example of a laptop that runs on Windows 7. This is by far the most popular operating system.

I advise you to immediately pay attention to the icon that displays the status of the Internet connection. It's in the notification bar.

If your internet connection status looks like this:

Then you need to first check if the drivers are installed on Wi-Fi and if the Wi-Fi adapter is enabled.

Right click on "My computer" and select "Properties". On the left select "Device Manager".

In a new window open the tab "Network adapters" and see if there is a device like Wireless Network Adapter (you may call it differently)... If you have such a device, then right-click on it and select “Properties”. Another window will open, make sure it says "The device is working properly."

If everything is about the same as mine above in the screenshot, then everything is fine, the driver is installed. And if there is no Wireless Network Adapter and you have unidentified devices, go to the website of your laptop manufacturer, download and install the driver for the Wireless Network Adapter for your model.

For more information on installing and updating the driver for your wireless adapter -.

We figured out the drivers.

Check if Wi-Fi is enabled on the laptop

If the driver is installed, but the Wi-Fi module is disabled, then the connection status will be the same:

Usually the wireless adapter on the laptop is turned on, but it doesn't hurt to check. Wi-Fi on laptops (netbooks) is usually turned on and off by a keyboard shortcut. On my ASUS K56cm, these are the keys FN + F2... But although when I press these keys, I get a message that the wireless adapters are enabled / disabled, but nothing happens. Look for the key on your laptop. FN and the key with a picture of a wireless network... Press them at the same time.

Some laptops may have a dedicated switch on the case that can be used to enable or disable Wi-Fi. For example on Toshiba Satellite L300 it looks like this:

Turn on or off the Wi-Fi wireless adapter in Windows 7

But the best way to check whether the wireless adapter is working or not is to go to the Network Control Center and see.

So on the notification panel, right-click on the Internet connection status icon and select "Network and Sharing Center".

Then select on the left.

Among the connections we are looking for "Wireless network connection"... If everything is fine and the Wi-Fi adapter is turned on, then it should look like this:

If the adapter is disabled then it will look like the screenshot below. Right click on it and select “Enable”.

Using the methods described above, we must make it so that the status of the Internet connection on the notification panel is like this:

This status means "No connection - There are connections available"- this means that the Wi-Fi adapter is turned on and there are available wireless networks for connection.

If the connection status is like this:

This means that Wi-Fi is on, but the laptop simply does not see the networks available for connection.

Error "Windows could not connect to ..."

We figured out the problem when the wireless network module is disabled or does not work at all. Now let's consider the case when the laptop finds available Wi-Fi networks, but when trying to connect to Wi-Fi it writes: "Windows could not connect to ...", where instead of dots the name of the network to which you want to connect.

If you have a network connection status such as in the screenshot above (through one, network with a yellow icon), then click on it, and you will see a list of networks available for connection.

Select the required network, click on it, then click the “Connect” button.

If the set is password protected, then Windows will ask you for the password. Write down the password for the network and click "OK".

And if everything is fine, then your laptop should connect to the Internet via wireless connection... And the status of the Internet connection should look like this:

But exactly at the moment of connection, the error “Windows could not connect to ...” very often appears. It looks like this:

Sorry friends, there is no definite solution to this problem. But I can download that very often the problem with such an error appears due to the settings of the Wi-Fi router. Maybe through the type of security and encryption that is installed on the Wi-Fi router, read more about this in the article. There may also be a problem with the distribution of IP addresses.

If you noticed, then in the window with the error “Windows could not connect to ...” there is an opportunity to run Troubleshooting, it is a sin not to use it. Try to run it, I heard somewhere that there are cases in which it helps :). But seriously, sometimes it really helps. Windows will check the readiness of the wireless adapter, check the settings, etc. And if it can, it will fix the problem that prevents you from connecting to Wi-Fi.

Just restart your router and then your laptop. It often helps.

Update

I noticed that in Windows this error appears when the settings that are saved on the computer for your network do not match the current network settings. I'll explain now.

For example, your laptop was connected to Wi-Fi, it automatically connected to the network. But you took and changed the password, or the type of network encryption. Now the laptop is trying to connect to the network, but the parameters do not match anymore, that's the error.

Enough, just delete the network on the computer and re-establish the connection. I wrote about this in the article

Conclusion

It's a great article, and I hope it's useful. I wrote it for half a day, with interruptions, of course, there were still problems with adding screenshots to the site, but I seem to have solved it.

I tried to collect all the necessary information that should help you solve the problem that occurs when connecting a laptop or netbook to Wi-Fi. If I forgot to write something, then I will definitely supplement the article in the future, I will also be very grateful if you share information in the comments that helped you solve the problem with connecting to a wireless network.

If you have any questions, then ask them in the comments, we will try to figure it out. Good luck!

Hey! Your laptop can't see Wi-Fi? It's OK! The owner of a cool laptop himself, and this also happens. Today I will tell you why this happens, and how everything can be quickly fixed. Nothing difficult will be!

But if suddenly you did not solve your problem, or something remained unclear, describe your situation in great detail in the comments to this article, and I will try to quickly help.

Let's go over the main reasons already and see the ways to fix the error.

Causes

Honestly, there can be a lot of reasons. It is very difficult to identify the exact reason remotely, so if you write your case in the comments, write in great detail. Try to find something close to your case in the text below and try to fix it - it certainly won't be worse.

Universal advice! If you don't know what to do, restart your router and laptop immediately. In 99% of all cases, the problem will be successfully fixed.

And here is my list of TOP problems:

Something has malfunctioned somewhere - cannot be diagnosed. It is treated by the aforementioned reboot.
There is no network itself.
The adapter is turned off.
Airplane mode.
The driver crashed or was not installed.
Problems on the router.
Breaking

With the first point, we seem to have figured out everything, proceed to the nuances for each next one. If this does not suit you, feel free to skip it.

No wireless network

In the literal sense, he does not see, because she simply does not exist. How to quickly check - look on other devices (from the phone). Is there this Wi-Fi there? If there are no other devices at hand - can you see other networks?

If other devices see everything, but there are no networks on your laptop, and you are in the same room with an access point, then most likely this is not the case. But often the network is overestimated for capacity, and it simply does not finish.

Disabled Wi-Fi adapter

Did you know that Wi-Fi on a laptop can simply be turned off. Well, turn it on accordingly. First, let's see what's in your tray!

Examples are given forWindows 10. OnWindows 7 and other models will be pretty much the same.

If you have it like this - and says "No available connections" - then most likely Wi-Fi is simply turned off. You can enable it in several ways - through the buttons and through the settings. Let's briefly analyze each method.

Power buttons

Previously, separate switches, or even buttons, were allocated to turn on Wi-Fi on a laptop. Now all this is usually turned on by the Fn + F keyboard shortcut. See example below:

On my ASUS laptop it is turned on by pressing Fn + F2 as in the picture above. Take a closer look at your function keys, find the icon for your model and try to turn it on. Inclusion is not the topic of this article, I will cut a lot. If you have any questions - in the comments.

Enabling in the quick bar

Especially for the top ten. Users of other operating systems can skip. For this status:

Click on notifications and select Network:

Turning on the adapter

Another option. The adapter will work, but is simply not enabled at the moment. Universal way for all systems. We do it in steps:

Right-click on our network connection and select "Network and Sharing Center" (Windows 7) or "Network and Internet Settings" (Windows 10):

Next, go to the adapter settings (on the seven in the left column - Change adapter settings)

In the window that opens, we find our wireless adapter(there may be wired adapters that we do not need, but if you want, you can turn them on), right-click on it and select "Enable":

Everything should work!

Autodiagnostics

Cool thing if you don't know how to figure it out, but not suitable for all cases. You can have the computer try to fix the problem on its own. As in the previous section, we get into "Network and Internet settings", and there we select "Troubleshooting":

The operating system will think something, try to offer you tips ... and Wi-Fi will work!

Well, or it won't work) For me, it's easier to turn everything on with your hands. But to diagnose the cause, it is quite possible to use it. The same is on Windows 7.

Airplane mode

Also an innovation. It happens that you turn it on by accident and you don’t understand what’s the matter. In the tray, it looks like this:

And it turns off by a similar click on this blue button (the panel is called up by clicking with the left mouse).

Driver

Often there is no driver in the system either - either it was not there before, or it flew off from some action, or maybe it's just a new card. First you need to check its condition, and therefore install it - so as not to do unnecessary things.

Right-click on the Start button and select "Device Manager":

We are looking for the "Network adapters" tab, and there we are trying to find our wireless adapter. As a rule, it contains the word Wireless in its name:

In my case, everything is fine with him. But it happens that instead of a beautiful blue icon there is some kind of exclamation mark, or even worse - there is no adapter at all in the devices. In general, if there is a problem, it is easier to change the driver. I will not refer you to the manufacturer's website, as some other publications do, the easiest way to use Driver program Pack Solution:

drp.su- go and download

The program itself will find problems in the hardware, outdated drivers and try to fix everything. Now, as for me, this is the best free solution for small problems like installing a driver on Wi-Fi.

Problems on the router

It is not possible to analyze all possible problems that may affect the visibility of the network - there are a lot of router models. I don't see any point in poking around in attempts to show something in between. I will list the main thoughts about the problems on the router in the topic of our article, and if you really need to configure something, use the search on our website, find your router model and do everything as written.

I give screenshots from my model fromTP-Link. In other models, everything is about the same.

Channel

The channel must be in the Auto position. Experts can set something else, but there is an option to get into the wrong channel, and the network will not be visible.

SSID and visibility

Sometimes the laptop just doesn't like the SSID of the network - that's its name. It is enough to change and everything will work as it should. Another option - someone made it invisible to everyone (and this is possible) - here it is enough to set visibility for everyone.

Breaking

If none of the above helps, then there is an option that our adapter has died. If you do not understand yourself, it is better to contact the specialists who will make the final diagnosis. It's easy to check - connect an external Wi-Fi adapter or internal card... What's cool - on laptops, Wi-Fi is easily replaced, which means that repairs will not cost a lot as in the case of a processor or video card breakdown. And it happens that it is even easier - for example, the loop is sealed off. This can be easily fixed in a day.

That's all! Hope I helped you solve the problem and get your laptop to look for the wireless networks of all its neighbors. If you suddenly have questions, feel free to write in the comments. We will decide on an individual basis! Have a nice day, everyone.
