The laptop does not see one network. The computer does not detect a wireless Wi-Fi network

Sometimes laptop users are faced with the fact that the equipment stops seeing the Wi-Fi network. This problem can have several causes. They lie either in the device itself or in the router.

Find out if there are problems with the router

First of all, you need to check if there is a problem in the router. To do this, you need an additional device, such as a smartphone. Try to find a network with it. If the equipment connects to Wi-Fi and accesses the Internet without problems, then the problem is exclusively in the computer. If other devices also do not see the network, you need to fix the router. There are several ways.

Reboot

Turn the router off and on using the button, usually located on the back of the case. This will restart all processes running by it. After it boots up again, try to find the network.

By pressing the button located on the back of the case, you can reboot the router

Reset options

Perhaps the router settings have gone wrong for some reason. The easiest way to restore them is to reset the options to their default values. To do this, on the back of the router, hold down the Reset button for 10-15 seconds. When the icons start flashing, the router will reboot. The button can be released - the settings are reset. Check again if the network is working.

Pressing the Reset button will reset the router settings

Reconfiguration

After resetting the settings, all parameters must be set again:

Also try connecting a LAN cable or modem directly to your computer to see if it works or not. Maybe the Internet is not paid or there are problems on the operator's side. If so, then the problem should not be solved with a computer or a router.

Channel change

If there are several devices connected to a Wi-Fi network at home, it is quite possible that their frequencies intersect with each other. Therefore, it is worth trying to change the settings. Go to the Wireless Setting section and set a new value for the Channel parameter.

Set a different value for the Channel parameter so that there is no conflict in the network

Troubleshooting a laptop

If the problem with the network occurs exclusively on a laptop, then you need to check if the Wi-Fi adapter is activated and if the necessary drivers are installed.

Please note if you do not have a section WiFi settings, this may indicate that this module is not included in the package of your laptop and it is not capable of receiving wireless signal. In this case, you will have to purchase an external receiving device separately.

Module activation

It is possible that the adapter responsible for working with Wi-Fi is deactivated. There are several ways to enable it. See if there is a special button with a signal icon on the laptop case. Just click on it to activate the module. Also inspect the F1-F12 keys, one of them should enable and disable the adapter. Often the default combination is Fn + F5.

To turn on the Wi-Fi adapter, try pressing the combination Fn + F5 The button to turn on the Wi-Fi adapter can be located on the laptop keyboard You can turn on the Wi-Fi module on some laptops using the button on the case

Activating the module using Windows

Also, the module can be enabled through the system settings:

After that, try to connect to the network again.

Checking Drivers

For correct operation computer components need drivers. Initially, they are installed automatically, but over time they may no longer be relevant, so you should install them manually again:

1. Expand Device Manager. You can find it using the system search bar.

   

   You can find device manager using the search bar

2. A list of all devices connected to the computer will be displayed. Locate your wireless adapter (if there is more than one, follow the steps below for each), select it, and proceed to update drivers.

   

   Select the adapter and click the "Update Drivers" button

3. Find the name of the adapter on the Internet latest version drivers for it. It is recommended to download drivers only from the official website of the manufacturer.

   

   Drivers are safest to download from the router manufacturer's website.

4. After downloading the drivers to your computer's memory, return to the installation procedure and select manual search.

   

   Select the option "Search for drivers on this computer"

5. Specify the path to the previously downloaded file and wait until the installation is completed. Then restart your computer for the changes to take effect and check if Wi-Fi is working.

What to do if nothing helped

If you have completed all the steps described above, but Internet access has not appeared, there is only one option left - the Wi-Fi module is broken. You won’t be able to fix it yourself, you will have to contact the service center so that specialists can do it. If the warranty period has not yet expired, assistance will be provided free of charge.

Thus, the laptop may not connect to the network for two reasons: the router is not functioning correctly or the Wi-Fi module is not working. To fix the router, you need to reboot or reset its settings. To make the module work, you need to enable it and install the drivers.

Today's Internet technologies are at a very high level. This manifests itself in the spread of wireless connections to the Web using Wi-Fi. However, there are situations when a device designed to receive such a connection (laptop, tablet, smartphone) does not want to work in normal mode. Lack of access to the World Wide Web modern people- this is worse than the "plague", the dependence is so strong. What is the cause of the malfunction, and how can it be fixed?

Top Causes of Wireless Network Failure

Actually, in order to start repairing, you need to determine the root cause why the laptop does not see wifi.

Here it is worth highlighting the main categories of faults:

• global problems;
• not working router (router);
• malfunction of the wireless network module on the device;
• lack of network card drivers;
• software settings wireless internet in OS.

Almost all the reasons when not visible wifi network on a laptop, can be fixed at home. But this must be done with extreme caution so as not to aggravate the problem.

Global Wi-Fi malfunctions

Common problems include the complete absence of the Internet on the line due to the provider (for example, preventive shutdown of the Internet everywhere), the limited operation of the router, as a result of which there may be no signal (all transmitting devices have a limited range), as well as external factor, for example, a power outage at the central control panel of the provider company.

What can be done if there is no wireless Internet due to remoteness from the router? You can move to a closer room so that the signal appears. The fewer obstacles (walls, rooms, household appliances) will be between the router and the laptop, the stronger and more stable the signal.

Problems with the router

And here given type problems are already somewhat more serious, although it can be corrected independently. First of all, you need to make sure that the router is working normally. To do this, you should try to connect another device via Wi-Fi. If the signal is detected, then the problem is exclusively in the device receiving the signal. If not, then somewhere there is a breakdown in the router itself.

The first step is to try simple measures- just turn off the power from the router, wait 10-20 seconds, then turn it on again. It happens that the router simply “freezes”, and rebooting it restores functionality. If this does not help and the laptop still does not see wifi from the router, you need to move on to the second option.

It is necessary to check whether the incoming network cable. It happens that due to a slight deformation, movement, the cable may move away, and as a result, the connection will not be established.

Another option, how to find out why the laptop does not see wifi, is to directly check the incoming connection. To do this, you need to connect the main Internet cable to the device. If access appears, then the problem is somewhere inside the router or its settings.

Important! Sometimes, Wi-Fi interference can be caused by household appliances, such as a microwave, oven. But this is more the exception than the rule.

Laptop malfunctions

Here the range of troubleshooting is very wide, from technical reasons to software that can block the work on the Web. As with a router, almost everything can be fixed by yourself, but you need to know where and what to look for. By the way, if it is not clear what to do if the laptop does not see wifi, then it is better to immediately take the equipment to a service center, where specialists will quickly fix the problem.

Technical reasons for the lack of Wi-Fi due to the fault of the laptop

There are several options here. The most common is to disable the wireless connection button on the laptop keyboard. It is located near the F4-F5 keys. Press again to turn on Wi-Fi.

Another option is to turn off the toggle switch on the front of the device. In a similar way, you need to move the slider to the right position, and wireless Internet should appear. As you can see, these problems are easily solved in a few seconds. But sometimes the reasons why the laptop does not see wifi are more serious.

For example, the failure of the network card of the laptop. No skill and knowledge will help here if this component has burned out or does not work for another reason. Only purchase will help new board, and some time will have to stay without the Internet.

Software problems with Wi-Fi connection

IN this case There are a lot of malfunction options, but most of them are eliminated very easily:

1. Conflict with antivirus program installed on a laptop. It is likely that this software simply blocks access to the Network. Therefore, you should temporarily disable it and check access. If there are difficulties, how to connect a laptop to wifi with the antivirus turned off, then you need to immediately configure the antivirus, or install some other software.
2. Firewall. The standard Windows Network Defender can also add problems, so you need to open its settings and make sure that the specified wireless Internet channel is not in the list of dangerous connections. If present, then the laptop does not see wifi. You need to completely disable the firewall or remove this channel from its blacklist.
3. Technical failure of network resources in the operating system. In this case, figuring out what to do if the laptop does not see wifi can be problematic. Sometimes it happens that the installation of any programs entails changes in the network settings. This problem is especially relevant when installing working programs, cryptographers, modules that require work with secure connections, and so on. If given fact takes place, then you need to identify the source of the problem, and try to do a system restore. But more on that later.
4. Installing third party software. It is likely that the program is installed for wifi distribution from a laptop. If its settings are incorrect, the device simply turns into a distributing element, and there will be no connection on it. But this is a very rare error.
5. But the failure of network drivers is the most common situation for laptop owners. "Crooked" installation, non-original assembly - there can be a lot of reasons for incorrect operation of network drivers. But the result is sad - the laptop does not see wifi, and even there is no wired connection. And there is only one solution - removing the old ones and installing the official packages, which can be found on the official website of the laptop manufacturer.

Operating system recovery

This is, of course, the most radical decision, and may entail a variety of consequences. Although usually System Restore simply rolls Windows back to an earlier restore point. If such, of course, was made. When this operation is performed, the Wi-Fi connection will also be rolled back to the last working state.

By the way, the occurrence of difficulties, how to connect a laptop to wifi, is also associated with the clogging of the operating system with all kinds of garbage, temporary files. As a result, all processes start to run very slowly, conflicts arise, including in the network.

As the most difficult option for solving the problem with accessing the Internet via Wi-Fi - a complete reinstallation of Windows. This is the very last instance, when all means have been tried, but none has brought the desired result.

Additional ways to connect Wi-Fi to a laptop

There are several more ways to check the wireless network on your device.

The same program for distributing wifi from a laptop (to use this method, you need a second laptop with such software installed on it) will help determine the source of the malfunction. If the laptop sees the distributed Wi-Fi, the reason lies in the router. If not, in the device itself. This is very good way check on which side the disconnect occurred.

Alternatively, you can simply go to the Network and Control Center and public access, go to the "Change adapter settings" menu. All installed adapters, including wireless ones, should appear in the window that appears. It is likely that it just needs to be turned on. Or install.

Afterword

Of course, many of those users who have computer equipment at home are quite savvy in terms of finding faults and fixing them. However, Wi-Fi is a special case as it requires programming skills. Therefore, it is better not to go deep, but to turn to specialist repairmen.

You can identify the source of the signal interruption, and then repair either the laptop or the router.

Many users sooner or later face this problem. The reasons why Wi-Fi does not work on a laptop may be different. You may have recently installed a new operating system, bought a new router or reflashed the old one and others.

In general, if you are also in this situation, and you are unable to connect your laptop to a Wi-Fi network, then in this article we will look at several ways that should help you connect your laptop to Wi-Fi.

Let's start with the simplest - reboot the router. To do this, unplug the power supply from the outlet, wait 10 seconds and plug it back in. Then reboot your operating system.

Network Diagnostics

Do network diagnostics. Although many will be rather skeptical about this advice, sometimes it can also help. Right-click on the wireless network icon in the tray and select "Problem Diagnosis". Windows will check, and if it finds a problem, it will suggest ways to solve it.

If after that, the laptop still does not see Wi-Fi, check Is the Wi-Fi enabled on the laptop?.

Find the wireless network icon on one of the F1-F12 buttons, I have it F2. Also on the button itself, near the power button or touchpad, there should be a light indicator that indicates that Wi-Fi is on. Specifically, in my case, if Wi-Fi is disabled, the indicator light is on. To turn it on, press the combination Fn + F2.

You also need to check that the network card is enabled. To do this, right-click on the wireless network icon in the tray and select "Network and Sharing Center".

In the next window, click "Change adapter settings".

If you have "Wireless Network Connection" grayed out, right-click on it and select "Enable".

After that, the icon should become colored. This indicates that the network adapter is enabled and the laptop can connect to the Wi-Fi network.

Checking Drivers

Check network adapter drivers. Click "Start" and write in the search bar "Device Manager" and follow the link you found.

Expanding the List "Network adapters". The desired adapter will be called something like: model name and "Wireless Network Adapter" (may be written Wi-Fi).

First you need to make sure it's enabled. Therefore, right-click on it, and if there is an item in the menu "Engage", click on it.

Now pay attention that there is no yellow exclamation mark or red cross near the adapter. If you have the same as in the figure below, then everything is fine with the installed drivers. If you have one of the mentioned signs (in the figure I indicated with an arrow how it might look), you need to install or update the drivers.

If your laptop came with a disk with drivers for installed devices, use it and reinstall the driver. If this does not help, and the laptop still cannot connect to Wi-Fi, go to the official website of your laptop manufacturer, download the drivers for the network adapter from there and install them.

You can read about installing drivers in the article:.

Also, to update or install missing drivers, you can use the free program Driver Pack Solution.

Checking the WLAN AutoConfig Service

This service is responsible for wireless network adapters, and if it is not running, then the adapters will be unavailable, respectively, the laptop will not be able to connect to Wi-Fi.

We go to the "Start" menu and write in the search bar "Services". Let's move on to the relevant section.

Then in the list we look for "WLAN AutoConfig Service", right-click on it and, if it is disabled, click "Run".

Checking your router settings

Router settings can go astray, and not always through the fault of the user. Perhaps the password for accessing the network was simply changed.

If your wireless network icon is muted, and there is a yellow star next to it, click on it with the mouse, select the network and try to connect to it, having previously found out if the access password has changed. The reason may be this.

Now let's go to the router settings. There is already a detailed article on this topic on the site, by clicking on the link, you can read it.

If, for some reason, they have gone astray, you need to adjust them. In my case, you need to follow the link "Wireless Network Setup Wizard". You may have slightly different menu items, it all depends on the model of the router, but you need to do the same.

Make sure you check the box "Enable Wireless".

Also pay attention to the section network information (LAN). You may need to change the settings here according to the provider.

I hope at least one of the tips helped you solve the question: why the laptop does not connect to Wi-Fi, and now your device is successfully connected to the network.

I tried everything to connect to the network, after the children stumbled something on the computer ... And this article ....... not even an article but a picture helped solve the problem for such a kettle like me .. All you had to do was press two buttons to connect to the F5 / Fn router and it all worked ....

Answer

hello, the user's comment helped me, attach it to the article because I'm probably not the only one like that, that's what he writes
SALEX 12/03/2017 at 00:00 I tried everything: there is firewood, and Wi-Fi is turned on, and everything is in order in the device manager, but the network is gone. As a result, I found a way out: “You enter the control panel, you find equipment and sound , it has the name "Setting default mobility settings", you go there, the window "Windows Mobility Center" appears, in the column Wireless network you need to activate the button "Connect wireless network"And immediately a connection with the router will appear. After connecting, you will forget the password and enjoy. Good luck."

• 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 if you say in plain language, That 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 public place. It is correct, perhaps it was simply turned off or access was limited (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 the installation of the necessary driver for Wi-Fi is required. 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.

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 the context menu and select "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 to reverse side router case or on the manufacturer's website. On the router page, you need to find "Advanced settings", the "Wi-Fi and network settings" tab. You need to set the "Enable wireless connection" flag. If the flag is on, but for some reason the problem remains, then the last way is to change the channel on which the router is running. 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.
