• Reasons why the laptop may not see the wi-fi network
• Ways to Fix No Wi-Fi
• Conclusion

Welcome friends. In this note, we will consider why the laptop may not see the wi-fi network. To begin with, it’s worth figuring out (albeit briefly) what wi-fi is, what its principle of operation is and what it usually requires for this.

So, to put it in layman's terms, wi-fi is nothing more than a wireless way to connect digital devices. It is important to understand that with it you can not necessarily go directly to the Internet, it's just a way to build wireless networks (like bluetooth, for example).

In order to access the Internet, this wi-fi network must be connected to a router (special modem), which, in turn, provides access to the global web (via telephone, network cable or in any other way).

It follows from this that if your device (laptop, phone, tablet) has a Wi-Fi connection, then this does not mean that it will immediately connect to the Internet (maybe this will seem obvious to someone, but some users may think that way ).

2 main situations when you can not connect to wi-fi

1. The reason is in your device
2. The problem is in the wi-fi network (that is, in the modem on which this network was created)

In order to eliminate problems in your laptop, you need to connect to an existing wi-fi network from another device, for example, from your friend's phone. To do this, as usual, take a smartphone (tablet, beech) from him, search for available Wi-Fi networks and connect to the one you need.

As a result, if your router is configured correctly, your friend’s smartphone connected immediately and without problems, then you should look for the reason in your device (more on this below).

In the second case, you are sitting alone (or with a company) and cannot connect to a wi-fi network, for example, in a public place. It is correct, maybe they just turned it off or restricted access (for example, by the number of simultaneously connected devices). In such a situation, you need to contact the administrator. Or, if there are problems with the modem (your, not your neighbor), then you need to either reboot it or reconfigure it.

That is, the first step is to decide where the malfunction is, and then delve into its solution.

Reasons why the laptop may not see Wi-Fi

Now let's take a closer look at the main points why there is no connection to the Wi-Fi network:

• To begin with, it is worth noting whether Wi-Fi is enabled in the "beech". This is easy to check, at the bottom near the clock, click the corresponding icon. If no available networks appear there, then most likely it is disabled.
• Connection failed. This can be most often due to modem errors. You can simply reboot or reconfigure it. To do this, just look at your modem and find the wi-fi indicator - it should be on.
• Is the driver installed and what is its version on the laptop. Very often, if the "beech" is new or the operating system was reinstalled on it, then installation is required the correct driver on wifi. If this is not done, then you will not be able to enter the network.
• Wifi stopped working on laptop. The reason may be a breakdown of the corresponding adapter inside the device. Here only repair with its replacement.
• Run out of money on the internet. In such a situation, by itself, you won’t be able to access the Internet via Wi-Fi. You just need to put money into the account and the problem will be solved.

Conclusion

As you can see, there can be quite a lot of reasons, we have considered only the simplest and most popular ones. No need to take it lightly simple ways solutions such as checking the funds on the account or restarting the laptop, very often they help to solve the current problem.

It is worth starting with the information presented above, and then moving on to deeper and more individual solutions to your issue. This concludes the solution of the question why the laptop may not see the wi-fi network, what to do in the first place in such a situation. Thank you for your attention, if you have any questions, then write them in the comments.

Developing wireless networks, developers came up with the wifi standard. This is when one or more computers connect to wireless hotspot access and through it go to the Internet. Or through a router. Before finding out the reasons why the laptop does not see wifi, we think it would be logical to know something about this technology.

How should the term be understood?

When we ask ourselves why the laptop does not see wifi, we mean the absence of the Internet. To tell the truth, this is not entirely true. It's just that wifi is, and if a device is equipped with it, then it is certified to work in these networks, that is, it is a guarantee of normal functioning for its intended purposes. Just like there are Xerox copiers, and there are other suppliers. However, out of habit, people call any paper multiplier a “copier”.

wifi equipment

Among most devices for wireless access, two categories of equipment can be distinguished: "access point" and There is also an extended access point - a multifunctional wifi device.

The hardware part of the equipment is similar, it differs in software firmware and, as a result, in the quality of work. If you have problems with the network, and you think that the laptop does not see the wi-fi router, then the problem is not always in the machine itself. May be underdeveloped software firmware router that causes unstable communication with the access point.

Optimal choice equipment with high-quality software should include:

• Prominence of the manufacturer (branded models are less likely to "buggy").
• Careful study of even top-class models. It is recommended to do a review with a specialist.

How to connect to wifi. Connection setup

One way is to use the services of cable network providers, and then install wifi equipment on a wired connection.

The next option is to connect through the appropriate access point in the local network of the provider, if such a service is provided to them.

The access point is a hardware amplifier of radio waves with the function of receiving and transmitting content. From the PC, a wifi standard radio signal is received, which is received by it. The signal is unified for equipment from different manufacturers, which allows you not to develop thoughts like “the laptop does not see wifi, probably this is due to the incompatibility of my equipment with the access center.”

Connecting wifi in windows xp via laptop

Step by step setup discussed below.

1. Turn on with a hardware button or a key combination (depending on the model). In this case, as a rule, the indicator light should light up - a light bulb signaling that the receiver is turned on.
2. For some laptop models, enabling the wi-fi module is provided by a special instruction that regulates the procedure. If necessary, check if this is the case in the relevant documentation.
3. If your receiver uses Wimax technology, you can configure this mode of operation using special software.
4. Enable the wireless access service (right click on the icon My Computer - management - services and applications - services - wireless settings - start if the service is not running).

If the laptop does not see the wifi router, and the system reports this, then most likely a special driver utility from the manufacturer is responsible for managing the wireless connection wifi equipment. Open "Network Neighborhood" - "view available wireless networks".

If the operating system should take over the wifi management functions, you need to click on the phrase "Change advanced settings". On the "wireless networks" tab, check the "Use Windows to configure the network" checkbox.

When you are in a free access zone, for example, in an Internet cafe, all that remains is to connect to the nearest access point found and enjoy Internet access.

Connecting wirelessly to the Internet using a laptop can be difficult for a number of reasons, often unrelated. To find the reason for the lack of a signal, it’s worth starting with, by checking the router and Wi-Fi adapter, you can identify and solve the communication problem with 99%.

Checking the access point

First of all, check the status of the router, often the equipment just freezes and needs to be restarted. Therefore, having found an atypical indication of the router, turn it off for a couple of minutes and start it again.
If it was an internal hang, then re-enabling should resolve the issue and the laptop will detect again available Wi-Fi net. If these actions did not lead to the expected result, it is worth checking the configuration of the access point.

Often, power surges and internal conflicts of the router lead to a reset, from which the device loses not only wireless access, but also the connection to the Internet. This problem is solved by authorization on the web interface of the router at the following addresses:
192.168.1.1
192.168.0.1
Depending on the equipment model, a different address is assigned, and entry is made from any Internet browser. After the configuration page opens, check the settings, and the volume.

If the check showed that the settings were reset to factory settings, you should configure the router (on your own or resort to the help of specialists). Usually, after the reboot that follows the end of the configuration, the laptop will find a new available Wi-Fi network. If these measures were insufficient, and the problem remains relevant, we check the laptop.

Checking mobile computer

Our diagnostics of the problem reached a dead end at the stage of checking the access point, so it is worth looking for a solution in the computer itself. And first, let's see if the network equipment is active. Some laptop models have function key, used in combination with the "Fn" key, it then controls the state WiFi adapter, which can be displayed on the laptop case.

At the beginning, find the LEDs on the case, they are marked with graphic values ​​​​(we are interested in "antenna" or the inscription "wi-fi"). If an indication is found and it is lit, then the adapter wireless communication included in this moment works. If the indication is absent or does not light up, then you can try to turn on the adapter. Find the "F1-12" key with the antenna icon in the top row, and press it while holding "Fn".

In addition, there is a possibility that the connection is disabled programmatically - by means of the operating system. To check, go to the "Control Panel" section, which is responsible for network settings (for Windows XP - ""; for Windows 7 - the item "Change adapter settings"). Make sure " Wireless network connection" is active, if it is disabled - click right click mouse and the corresponding item from the context menu.

It may turn out that the network element is not in the connection lists at all. This means that the hardware is not installed or is not used in Windows. To check the performance of the network adapter, you should open the "Device Manager", and expanding the item " Network adapters" find wireless device(Wireless). If you need to enable it, then by clicking the "Enable" context item, you may need to restart the computer.
If the device is marked with an attention sign, then most likely the drivers are not installed correctly or are completely missing. Use the disc that came with your laptop and install the drivers before. They can also be found on the official website of the manufacturer by the model number of your computer.

P.S.

The above problems are only a part of the possible, the most common among ordinary users. Therefore, when looking for a cause, and its further solution, it is worth starting from the individual characteristics of the situation.

Unfortunately, many of us have encountered a problem when the laptop stops finding a wireless network, which creates tangible inconvenience. Given that the laptop can be used outside the home, the user may be left without the Internet at all. There can be many reasons for this little pleasant moment. But, as a rule, the problem is technical, or in the wrong operation of the software. To understand how to deal with the problem, we will analyze 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 connection is set up.

WiFi is the same local network, only without the need for cabling. Connection to the network occurs through a signal that is transmitted via radio waves. Such a system has gained popularity not so long ago. Even a dozen years ago, no one knew about it, and the signal distance was much less. To be precise, the signal can be sent to a distance equal to 100 km.

In addition, WiFi is a registered trademark that is being developed very actively. In 2014, data transfer rates over WiFi should increase to several Gbps.

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

The main reasons for the lack of WiFi

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

WiFi on laptop and router

It’s worth starting with the very basics that can be forgotten due to haste or inattention.

Make sure the receiving antenna is on. If the WiFi button does not work, then the problem is obvious. Not all laptop models have this switch, but some do. It looks, most often, not in the form of a button, but in the form of a latch. In other words, it depends on the manufacturer. With the switch, there may be a signature or an image 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 bottom panel of the operating system, to the icon next to the time. The image should show whether the wireless connection is currently active.

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

To check the activity without the help of this icon, you need to:

Checking available networks

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

For this you need:

1. click on the network icon in the lower right corner, on the bottom panel, next to the time.
2. Select "Connect to a network" 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 does the laptop not see the WiFi network? Perhaps the solution to the problem is right in front of you and takes only five seconds of your time. But there are also more severe cases. Consider the most common options.

router

Make sure 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 it is active.

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

Drivers

As you know, any equipment 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 "device manager" section there is a line "network adapters", which should contain the name of the router, if the problem is in the drivers. Right click on it and see the driver version. Compare it with the real version, which can be found on the Internet.

If the version is outdated, then download the new one and install it. It is best to download from official sources. Drivers for equipment are distributed by developers for free, and it is not worth risking the "health" of your operating system in vain.

signal distance

In case, after searching for a network, the answer appears: "No connections available" - 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 simply may 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 stopped seeing it. 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 just 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 correctly with establishing an Internet connection, which often happens when the device sees wifi but does not connect. In addition, sometimes antiviruses interfere with creating a connection. If possible, it is better to try to connect the Internet without a router first. If everything is fine, 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. So if all else fails, try reinstalling your operating system. Perhaps all the problems come from here.

The laptop does not see the 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.

For this you need:

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.

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

How to set up a wireless network

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

The login and password are specified by the manufacturers of the router, and you can find this data in the instructions. There is also an address that will take you to Personal Area. 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 set using the network control center.

WiFi without internet due to Windows

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

Another reason may be a "blockage" of the system. System folders, over time, are clogged with unnecessary files and if you do not defragment, 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 on the laptop, or the availability of the necessary software. Subject to these points, WiFi will not present difficulties, and will delight the user with stable operation.

A fairly common problem for owners of laptops with Windows 10, Windows 7 or 8 (8.1) - at one point in the notification area, instead of the usual icon for a wireless Wi-Fi connection, a red cross is displayed, and when you hover over it, a message stating that there are no available connections.

At the same time, in most cases, this happens on a completely working laptop - yesterday, you may have successfully connected to an access point at home on it, and today this is the situation. The reasons for this behavior may be different, but in general terms - the operating system considers that the Wi-Fi adapter is turned off, and therefore reports that there are no available connections. And now for ways to fix it.

If Wi-Fi has not been previously used on this laptop, or if you have reinstalled Windows

If on this device If you have never used wireless capabilities before, and now you have installed a Wi-Fi router and want to connect and you have this problem, then I recommend that you read the article first.

If the wireless network was working, but now there are no available connections

If everything was working recently, and now there is a problem, try the methods listed below in order. If you do not know how to complete steps 2-6, everything is described in great detail (opens in a new tab). And if these options have already been tested, go to the seventh point, from which I will begin to describe in detail (because everything is not so simple there for novice computer users).

Remove the wireless Wi-Fi adapter from the device manager, install it again

To start the dispatcher Windows devices, press the Win + R keys on the laptop keyboard and enter the command devmgmt.msc, and then press Ok or Enter.

In the device manager, open the "Network Adapters" section, right-click on the Wi-Fi adapter, pay attention to whether there is an "Enable" item (if there is, turn it on and do not do everything else that is described here, the inscription should not be available connections disappear) and if it is not there, select "Delete".

After the device is removed from the system, in the Device Manager menu, select "Action" - "Update hardware configuration". The wireless adapter will be found again, drivers will be installed on it and, perhaps, everything will work.

See if the "WLAN AutoConfig" service is enabled in Windows

In order to do this, go to the Windows control panel, select "Administrative Tools" - "Services", find "WLAN Autoconfiguration" in the list of services and, if you see "Disabled" in its parameters, double-click on it and in the field "Startup type" set to "Automatic", and also click the "Start" button.

Just in case, go through the list and if you find additional services that have Wi-Fi or Wireless in their name, turn them on too. And then, preferably, restart your computer.

I hope one of these methods will help you solve the problem when Windows says there are no Wi-Fi connections available.

The laptop does not connect to a wireless access point or refuses to see the local network - an extremely unpleasant situation that confuses users.

Troubleshooting is often complicated by the fact that there is no way to go online and see how to fix the problem. To protect yourself from falling into a stalemate, it is recommended that you carefully read the possible causes of problems with your wireless or local connection as well as ways to solve the problem.

Possible reasons:

• Wi-Fi turned off.
• The wireless network is disabled.
• Drivers installed incorrectly.
• Incorrect router settings.

As for problems with detecting a local network when a cable is connected, here often the reason lies in mechanical damage to the wire or network card.

No access to Wi-Fi network

If the laptop does not see the wireless network, then the first step is to check if the adapter is enabled on the laptop. Take a look at the row of keys F1-F12: one of the keys should have the designation of the antenna receiving the signal. Find this key and press it in combination with the Fn button - for example, Fn and F2.

On some laptop models, instead of hot keys, a hardware switch is used, which is located in the front of the case. After pressing a keyboard shortcut or using a hardware switch, a message should appear indicating that Wi+Fi is on/off. You, of course, need to make it active.

But that's not all: sometimes the wireless connection in the system is turned off, while the adapter itself is working. To fix this issue:

1. Open the Network Sharing Center.
2. Go to the "Change settings" section.
3. Find your wireless network and make sure it works.

If the adapter is turned on, the wireless network is active, but you still cannot access the Internet, then it makes sense to check Wi-Fi drivers. This is especially true if connection problems started after reinstalling Windows.

1. Right-click on the "Computer" icon.
2. Open the Manage tool.
3. Go to "Device Manager".
4. Find the module among the network adapters wireless connection.

Even if it is written that the equipment is working correctly, do not be too lazy to go to the official website of the laptop and download the drivers for the Wi-Fi module of your particular laptop model.

Checking your router settings

If the laptop does not catch the wireless network, but you see that everything is fine in the system, then you should pay close attention to the router. Make sure the signaling device is working properly. Go to its web interface and see wifi settings.

1. Enter the address of the router in the browser (192.168.0.0 or whatever is specified on the router).
2. Open advanced settings and make sure Wi-Fi is turned on.
3. Save the correct configuration and close the router interface.

After application new configuration try connecting to the wireless connection again. To make it appear in the list of available networks, turn off and then turn on the Wi-Fi adapter on the laptop.

LAN problems

We figured out the wireless connection, now let's look at a more complicated situation - the device does not see local network, although you have connected an internet cable to the network card. What to do in this case?

First check if the wire is damaged. Often it is the faulty condition of the cable that leads to the fact that the laptop cannot detect the local network. If the wire is broken or cut, it must be replaced.

The second step is to check the connector network board into which the Internet cable is inserted. If you carelessly removed the cable or dropped the laptop, the connector could be damaged. The problem is solved in service center, where you will be replaced with a broken port. Another unpleasant situation of this kind is a burnt network board. It is also better to entrust the operation of replacing it to specialists: after all, a laptop is not a computer where modules can be changed at home.

But before you go to the service, be sure to check the network card drivers: they may have crashed. This can be done through the "Device Manager", the launch order of which we described above. The principle is the same - download the drivers for the network card from the official website of the laptop manufacturer and install them, and then check again if the local network is detected.

Today it is difficult to imagine the operation of a laptop or any other portable device without internet access. The most common way to connect to the World Wide Web is through wirelessly- by using WiFi networks router. However, often the user, when trying to get to the desired Internet, has various kinds of problems. One of them may be that the laptop does not see the Wi-Fi network. Consider probable causes occurrence of such faults. At the same time, let's leave aside very similar cases when a laptop finds Wi-Fi, but cannot connect to it, or connects, but the Internet still does not work.

Most of the situations in which the problem we have touched upon can be divided into two categories:

• The laptop does not see any Wi-Fi networks at all, although they definitely exist and are detected by other devices;
• The laptop does not specifically find your wireless network, but it sees the surrounding Wi-Fi networks.

Based on this gradation, we will identify the cause of the problem.

Why the laptop does not see any Wi-Fi networks

Such a malfunction is almost 100% related to the client device itself and its settings. Let's try step by step to check a few key points that can affect the visibility of wireless networks.

Is Wi-Fi enabled on your laptop

Any laptop equipped with a wireless adapter that provides the ability to search for Wi-Fi networks and establish a connection with them. Typically, such a module provides "On" and "Off" modes. So, you need to make sure that on your portable computer Wi-Fi the module is currently active. This will be indicated by the corresponding indicator light, the location of which depends on the laptop model.

If the module is disabled, it must be enabled. This is usually done in combination special key fn and one of the range function buttons F1-F12. You can find out which of the system keys is responsible for turning on the wireless communication module by the corresponding icon printed on it.

On laptops from some manufacturers, turning on / off the Wi-Fi module is carried out by a two-position toggle switch or a separate button.

If the laptop still does not detect wireless networks when the Wi-Fi adapter is enabled, proceed to the next step.

What is the status of the wireless connection in Windows

On this stage you need to check the connection status in the operating system itself. For this we go to Control Panel - Network and Control Center public access- Change adapter settings.

We find here a wireless connection and check its activity. If the icon is highlighted, then the connection is enabled, otherwise it must be enabled.

Right-click on the icon and select "Enable" from the menu that appears.

After that, the icon in the system tray (notification area) should change.

Are the drivers for the laptop's Wi-Fi module installed?

To check for the presence and correct installation of network adapter drivers, go sequentially along the path Control Panel - System - Device Manager. In the list we find the item "Network adapters" and expand it.

If there are no exclamation marks next to the device, then most likely the drivers are installed correctly. We will verify this by right-clicking on the name of the adapter and selecting the "Properties" line. On the "General" tab, the "Device Status" field should read "The device is working properly."

The "Driver" tab allows you to perform various manipulations with drivers - update, rollback or delete. If the required software is not available, it can be found on the Internet.

In theory, if there are no questions on all of the above points, then the laptop should easily see nearby Wi-Fi networks. If this does not happen, then there may be a problem with the laptop adapter itself.

The laptop does not detect my router's network, but it sees others

The most banal reason for such a metamorphosis is that your laptop is located too far from the desired Wi-Fi signal source. Despite the fact that modern routers have a fairly extensive coverage area, reception may be unstable in some parts of your house or apartment. In such a situation, it is necessary to correctly place the router so that all consumers are within reach. About that, you can find out on the pages of our website.

And yet, in most cases, problems with detecting the wireless network of one particular router are due to its incorrect configuration. Let's try to figure out which Wi-Fi settings can significantly affect signal quality. For example, let's take . Let's go into it administrative panel and choose a section Wireless mode– Wireless settings.

Immediately make sure that there are checkboxes next to the items “Enable wireless broadcasting” and “Enable SSID broadcasting” (the indicator on the router itself will signal the working status of the Wi-Fi network).

Now let's pay attention to the most important parameter - the channel of the Wi-Fi network. In Russia, 13 channels are used, but only a few of them can be optimal (least loaded) for you. It all depends on which channels nearby routers use. Try setting it to a static value (except 12 and 13) or Auto mode.

Reboot the router and check if the laptop now sees the target Wi-Fi network.

If it doesn't help, try experimenting with Wi-Fi settings - change channels, network name, adjust the MAC address filter. IN last resort, you can reset the router to factory settings.

There are times when Wi-Fi is no longer available on the computer. Why this happens and what to do in each case will be discussed in this article.

The problem can be of two types: the computer does not see the Wi-Fi network at all, 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 was lost.

What needs to be done first? You can restart the router or computer on which the network has disappeared. Make sure that the password is entered correctly and that Caps Lock is not turned on. 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"). For keyboard shortcuts to work, drivers must be installed on the keyboard. 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 on the keyboard, turned on the Wi-Fi module, but there is still no Internet, then open the "Control Panel". Select "Internet Networks" and in "Manage Sharing" select "Change adapter settings". Here you will see a list of all adapters. Click on "Wireless Network". 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: right-click context menu and choose "Enable". The wireless network becomes active. In case of an error, running "Diagnostics" helps Windows networks". The system itself can find and correct errors.

If after that the computer does not detect an available network, then reinstall the drivers on 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 found on the official website of your computer manufacturer or you can find a CD with a working driver that came with your computer. After installing the driver, you need to turn on the Wi-Fi module and see the work - if everything is 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. Masters can turn off the antennas. Then you need to disassemble the laptop case and connect them or seek help from specialists.

Problems with the router

If the problem is that the computer does not see only your router, but sees others, then you need to take the following steps. Find router settings and check wifi work 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 didn’t work out, the data on the ip-address and authorization in order to enter the page can be taken from the sticker attached on the back of the router case or on the manufacturer’s website. On the router page, you need to find "Advanced settings", the tab "Wi-Fi and network settings". You need to set the "Enable wireless connection" flag. If the flag is set, but the problem remains for some reason, then last way- this is a change in the channel on which the router operates. In order not to blindly change the channel, you can use the "inSSIDer for Home" program, which analyzes the frequency range of the channel. Channels 1 to 11 are US standard, most devices can do the job on these channels. Free can be 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 it to "Open System". The problem could 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 here: the "Administration" section, the "Update Firmware" tab.

Software

Why are there still difficulties? The problem may be in software. If you have System Restore enabled in Windows, then restore points will be shown in the log when you install 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. A 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 sees what it needs again.

Adapter failure

If nothing helped and the computer still does not see available networks, then there is a possibility that the Wi-Fi adapter could fail: it can burn out during operation, it needs good cooling. If it burned out, it will not be displayed in the "Device Manager", this problem will be issued during "Windows Diagnostics". It will need to be repaired or replaced.

So, we examined the most basic sources of problems when a computer crashes with Wi-Fi. Remember that any problem can be fixed if you know its causes.

Sooner or later, we all face a problem when our device (computer, tablet, laptop, smartphone) for some reason does not see the wifi network. It seems that they connected correctly, and everything was set up, but there are no available connections. Let's look at possible solutions to this situation.

Why laptop ⁄ computer does not see the WiFi network

I note that there may be several reasons, and we will start with the primary one: the work of the router itself. It is he who performs the main functions of an access point and provides us with a good connection signal. If there is a problem with the router, try rebooting it. If it is turned on and functioning normally, check its distance from the computer ⁄ laptop. Maybe it is because of the range that your device does not work.

Check if Wi-Fi is enabled on your laptop. On the working panel at the bottom, near the language switch, there is a corresponding icon (if networks are not displayed when you click on it, then Wi-Fi is still turned off).
If this is not the reason, we will have to check the operation of some systems of our laptop ⁄ computer (suitable for Windows XP, Windows 7, Windows 8 and Windows 10).

Let's analyze possible reasons no network:

1. your device simply does not see any of the Wi-Fi networks (they are not displayed as available) - let's call it error 1;
2. your device sees neighboring Wi-Fi networks, namely yours does not find - error 2.

• A hardware error pops up (i.e. network board error). In this case, your device does not see the wireless wifi adapter because it is either broken or there is a problem with its drivers.
• Driver not installed network equipment(we check the driver in the Device Manager tab, in the Properties folder). If necessary, install the driver or reinstall the software (from the disk or from the manufacturer's website).
• The wireless connection is turned off (we check in the network control center in the Wireless network tab or the Wireless tab network connection).
• The Wi-Fi module does not work (in case of a malfunction, the module must be replaced).
• Software failure or other problems (the help of a specialist may already be required here).

If you find out that your error 2, to eliminate it, use the change of the channel of the Wi-Fi network.
It is quite simple to do this through the Settings item on the Wireless tab (Wireless mode). You can select a channel number from 1-9, or you can check the Auto box. After saving the settings, you will need to reboot the router.

System Diagnostics

In case you have tried all the possible and impossible options, and nothing has helped you, you can use such a feature as system diagnostics. Go to the network control center, the item "Change adapter settings". Find the wireless connection shortcut, right-click on it, select the "Diagnostics" line. After that, your laptop (computer) itself will try to find malfunctions in operation and tell you how to fix them.

Why Android - smartphone does not see the WiFi network

Both in the case of a laptop and in the case of an Android-based smartphone, there may be several reasons for the lack of visible Wi-Fi networks:

• You are out of range of the router (sometimes just moving around the room is enough to find the network).
• Wrong access password entered, network authentication (the problem is solved by entering the correct password in a case-sensitive way or by rebooting the smartphone).
• Router freezing (the problem is solved by rebooting the router).
• Lack of support for router standards by a smartphone (see instructions for the router).
• A large number of connected devices (in the router settings you need to find the number of devices with which it can work, remove unnecessary ones).
• Installing new applications (this situation is typical for some Android devices, try deleting the last saved programs).
• Wrong setting router ( precise settings entered in the router menu).
• Broken router or smartphone.

Regular connection failures may indicate that the problem lies in the phone settings themselves. The output can be full reset settings to factory settings. This will usually require you to go to Settings and open the Security tab. After rebooting the phone, try to find the Wi-Fi network on a new one.

As you can see, there can be quite a few reasons for the lack of a Wi-Fi network, but the ones mentioned above are the most common and, in principle, should help.
