Why doesn't my laptop see the wi-fi network? The laptop does not see wi-fi

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

Common Causes of Wireless Network Failure

Actually, in order to begin repairs, 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 drivers network card;
• software settings wireless internet in the OS.

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

Global Wi-Fi faults

TO common problems applies complete absence Internet on the line due to the provider (for example, preventive shutdown of the Internet everywhere), limited action router, which is why there may be no signal (all transmitting devices have a limited range), as well as an 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 distance from the router? You can move to a closer room for the signal to appear. 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

But this type The problems are already somewhat more serious, although you can fix it yourself. First of all, you need to make sure that the router is working normally. To do this, try connecting another device via Wi-Fi. If a signal is detected, then the problem is solely in the device receiving the signal. If not, then it means there is a problem somewhere in the router itself.

The first step is to try simple measures- just turn off the power from the router, wait 10-20 seconds, and then turn it on again. It happens that the router simply freezes, and rebooting it restores its 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 slight deformation or movement, the cable may move away, and as a result the connection will not be established.

Another option for finding 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 there is interference in Wi-Fi work can be caused by working home appliances, for example, a microwave oven, an oven. But this is rather the exception than the rule.

Laptop problems

Here the range of troubleshooting is very wide, starting from technical reasons and ending software, which can block work on the Internet. As with the router, you can fix almost everything 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 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 in the area of ​​the F4-F5 keys. Pressing it again turns on Wi-Fi.

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

For example, failure of the laptop’s network card. No skill or knowledge will help here if this component burns out or does not work for another reason. Only purchasing will help new board, and you will have to be without the Internet for some time.

Software problems with Wi-Fi connection

IN in this case There are a lot of possible faults, but most they can be 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 you have difficulty connecting a laptop to wifi with the antivirus turned off, then you need to immediately set up the antivirus or install some other software.
2. Firewall. Standard network windows defender can also add problems, so you need to open its settings and make sure that this channel wireless Internet is not on 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 glitch 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 some programs entails changes in network settings. This problem is especially relevant when installing working programs, cryptographers, modules that require working with secure connections, etc. If this fact occurs, then you need to identify the source of the problem and try to restore the system. But more on that later.
4. Installation of third-party software. It is likely that a 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 itself. But this is a very rare malfunction.
5. But there's a glitch network drivers- This is the most common situation among laptop owners. “Crooked” installation, non-original assembly - reasons incorrect operation There can be a lot of network drivers. But the result is sad - the laptop does not see wifi, and there is not even a wired connection. And there is only one solution - removing the old ones and installing official packages, which can be found on the official website of the laptop manufacturer.

Restoring the operating system

This, of course, is the most radical solution, and can entail a variety of consequences. Although usually System Restore simply rolls back Windows to an earlier restore point. If one, of course, was done. When performing this operation WiFi connection will also roll back to the last working state.

By the way, difficulties arising in how to connect a laptop to wifi are also associated with the operating system being clogged with all kinds of garbage and temporary files. As a result, all processes begin to run very slowly, and conflicts arise, including on the network.

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

Additional ways to connect Wi-Fi to a laptop

There are several other ways you can check the functionality of 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 this software installed on it) will help determine the source of the problem. If the laptop sees the Wi-Fi being distributed, the reason lies in the router. If not, it’s in the device itself. This is very good way check on which side the disconnect occurred.

Alternatively, you can simply go to Network Sharing Center and shared access, go to the “Change adapter settings” menu. All of them should appear in the window that appears. installed adapters, including wireless. It is likely that you just need to turn it on. Or install it.

Afterword

Of course, many of those users who have homes computer equipment, are quite savvy in terms of finding faults and eliminating them. However, Wi-Fi is a special case as it requires programming skills. Therefore, it is better not to go deeper, but to contact repair specialists.

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

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

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

Most often, problems arise when it is not possible to turn on the Wi-Fi module itself on the laptop. And when Wi-Fi turns on, everything available networks The laptop finds it, but when I try to connect it says . You need to check whether the drivers are installed on the Wi-Fi adapter, whether Wi-Fi is turned on on the laptop, etc. Now we will do this.

I noticed that most often problems with connecting to Wi-Fi occur in Windows 7. It is on this OS that the network without Internet access error very often appears; I wrote how to solve this problem in the article linked above. In fact, as practice shows, there can be many 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’s not always the laptop, netbook, etc. that is to blame. There may also be a problem with the access point, that is, with the Wi-Fi router. And the first thing we need to do when a problem arises with connecting to Wi-Fi is to determine what the reason is, in the laptop or in the Wi-Fi router. Now I will consider the problem with connecting to your own router. Because if you are unable to establish a connection with someone else's Wi-Fi, then all the complaints are to the neighbor, it’s most likely his problem :).

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

As I wrote above, you first need to find the culprit. Before you make any settings on your laptop or Wi-Fi router, you need to understand what the problem is, which is why you can’t connect your laptop to Wi-Fi. You can just set it up in such a way that then you have to do it and set everything up again. Most best way To determine which device is hiding the problem, try connecting 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 another wireless network.

I think that you understood my point. If there are other devices 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 let’s try to solve it.

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

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

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

If the Internet connection status looks like this:

First you need to check whether the drivers for Wi-Fi are installed and whether the Wi-Fi adapter is turned on.

Click right click on “My computer” and select “Properties”. On the left select "Device Manager".

Open a tab in a new window “Network adapters” and see if there is a device like Wireless Network Adapter (You may have a different name for it). 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 normally.”

If everything is approximately the same as mine above in the screenshot, then everything is fine, the driver is installed. What if Wireless devices There is no Network Adapter and you have it unidentified devices, go to your laptop manufacturer’s website, download and install the Wireless Network Adapter driver for your model.

Learn more about installing and updating the driver for wireless adapter – .

We sorted out the drivers.

Checking whether Wi-Fi is turned on on the laptop

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

Usually the wireless adapter on your laptop is turned on, but it doesn't hurt to check. Wi-Fi on laptops (netbooks) is usually turned on and off using 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, nothing happens. Look for the key on your laptop FN and a key with a picture of a wireless network. Press them at the same time.

On some laptops it may be special switch on the case, which can be used to enable or disable Wi-Fi. For example on Toshiba Satellite L300 it looks like this:

Enable or disable the Wi-Fi wireless adapter in Windows 7

But the best way to check whether the wireless network adapter is working or not is to go to the network control center and take a look.

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, it will look like the screenshot below. Right-click on it and select “Enable”.

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

This status means “No connection - Yes available connections” - this means that the Wi-Fi adapter is turned on and there are available wireless networks to connect to.

If the connection status is like this:

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

Error “Windows could not connect to...”

We have sorted out the problem when the wireless network module is disabled or does not work at all. Now consider the case when the laptop finds available Wi-Fi network, but when I try to connect to Wi-Fi it says: “Windows was unable to connect to...”, where instead of dots is the name of the network you want to connect to.

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

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

If the set is password protected, Windows will ask you to provide the password. Enter your network password and click “Ok”.

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

But it is at the moment of connection that the error “Windows could not connect to...” very often appears. She looks like this:

Unfortunately, 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. It may be 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 notice that in the window with the error “Windows was unable to connect to...” you can run “Troubleshooting”, it would be a sin not to take advantage. Try running 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 is preventing you from connecting to Wi-Fi.

Just reboot your router and then your laptop. Very often this 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 current settings networks. I'll explain now.

For example, your laptop was connected to Wi-Fi, it automatically connected to the network. But you went and changed the password, or the type of network encryption. Now the laptop is trying to connect to the network, but the parameters no longer match, and that’s the error.

All you need to do is simply delete the network on your computer and re-establish the connection. I wrote about this in an 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 seemed to have solved it.

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

If you have any questions, ask them in the comments, we’ll try to figure it out. Best wishes!

Why doesn't Wi-Fi work on a laptop (netbook)? How to connect a laptop to a Wi-Fi router? Error “Windows could not connect to...” updated: February 7, 2018 by: admin

• Introduction
• 2 main situations when you cannot connect to wi-fi
• Reasons why a laptop may not see the wi-fi network
• Ways to fix lack of Wi-Fi
• Conclusion

Greetings, friends. In this article, we will look at why a laptop may not see the wi-fi network. First, it’s worth understanding (albeit briefly) what wi-fi is, what its operating principle is and what it usually requires for this.

So if you say accessible language, That wifi is nothing more than wireless way communication of digital devices. It’s important to understand that you won’t necessarily be able to get out right away with it. to the Internet, this is just a way to build wireless networks (such as bluetooth).

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

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

2 main situations when you cannot connect to wi-fi

1. The reason is 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 with your laptop, you need to connect to the existing Wi-Fi network from another device, for example, from your friend’s phone. To do this, as usual, take his smartphone ( tablet, "beech"), 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 group) and cannot connect to a wi-fi network, for example, in a public place. This is correct, perhaps it was simply disabled 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 (yours, not your neighbor), then you need to either reboot it or reconfigure it.

That is, the first thing you need to do is decide where the problem is, and then go deeper into solving it.

Reasons why a laptop may not see Wi-Fi

Now let’s take a closer look at the main points why the connection to the Wi-Fi network does not occur:

• To begin with, it is worth noting Is Wi-Fi turned on 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.
• The connection has failed. This can most often be 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 it installed driver and what is its version on the laptop. Very often, if the beech is new or has been reinstalled operating system, then installation is required the required driver on Wi-Fi. If you do not do this, you will not be able to log into the network.
• Wi-Fi stopped working on the laptop. The reason may be a breakdown of the corresponding adapter inside the device. There is only repair and replacement here.
• The money on the Internet has run out. In such a situation, of course, you won’t be able to access the Internet via Wi-Fi. You just need to deposit money into your 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. Don't take it lightly simple ways solutions such as checking the funds in the account or rebooting the laptop, very often they are what help solve the current problem.

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

Very often, laptop users encounter troubles when turning on or setting up Wi-Fi. The procedure itself seems quite simple, but difficulties and snags often arise due to which the laptop does not connect to wi-fi. What to do if the Internet suddenly stops working? To answer this question, here are recommendations on how to deal with troubles when your laptop does not see WiFi.

For turn on wifi, you need to do two simple steps. And these actions will depend on the manufacturer and model of the laptop. First, we present the inclusion options for the most popular manufacturers.

How to enable WiFi on a laptop

• If laptop ASUS does not connect to wifi, you will have to press the key combination FN + F2.
• Same settings on laptop Packard bell And Acer can be called by the keyboard shortcut FN + F3.
• Laptop HP contains a special button with a symbolic antenna on it. But there are models in which wi-fi can be easily turned on by pressing FN + F12. There are also options for HP laptops that provide regular button with a picture of an antenna.
• Chinese manufacturer Lenovo provided an option where the connection is connected using the FN + F5 key combination. But there may also be models that have a special switch for wireless networks.
• Depending on the model on Samsung laptop You can connect to a wireless network using the FN, F9, or F12 keys.

In order for a laptop to connect to wi-fi, each manufacturer came up with their own original ways. To view this procedure in detail, you should use the user manual included with the laptop. Almost everyone modern laptop equipped with an FN button. It allows you to perform the most different functions to connect the device with other devices. If, for some reason, such a button is missing, then instead there is a switch or another special button. All of them are easily recognized by their characteristic antenna pattern.

Reboot the router

Before you start troubleshooting the problem of lack of Internet. Reboot your router by turning it off and on. In this case, all router settings are saved.

Checking and setting up drivers

When making settings on a laptop, you need to check whether the necessary drivers for this are present and their functionality. The purpose of this check is that the drivers must be present and involved in at the moment. To do this, you will have to enter the “Control Panel”, then select “Network and Internet” and here open the “Network and Sharing Center” item, in the left column select “Change adapter settings”

A window will open showing two items, Wi-Fi and Ethernet. In the screenshot below you can see that the laptop is connected to the network via WiFi, but the network cable is not connected.

If the entry is not displayed in the wi-fi adapter, then this is a clear sign of a problem with the drivers. In addition, a sign of driver failure may be yellow icon with an exclamation point.

There are times when there is no entry for the adapter at all. This means that the drivers are not installed and the system does not see the adapter. Drivers can be installed from the disk that came with the laptop or found on the manufacturer's website.

If yellow is displayed exclamation point, click on it with the mouse and select “Engage” in the window that appears.

Also, the reason that wi-fi stopped working may be the power saving mode, which is involved in given time. To disable it you need:

1. enter the “Control Panel”;
2. find the item “Power supply”;
3. select "High performance";

Having dealt with all these simple manipulations, you can put things in order with the wi-fi drivers.

Turn on the wi-fi adapter

To connect the wi-fi adapter we also perform a number of steps. Open the “Control Panel”, then select “Network and Internet” and here open the “Network and Sharing Center” item, in the left column select “Change adapter settings”. There is "Wireless" network connection", which is wi-fi adapter. In order to connect to wi-fi, you need to open the dialog box with the right mouse button and here use the “Enable” item.

Connecting to the access point

All that's left to do is connect to the access point. But first of all, you should make sure that it is active. In the right corner at the bottom of the screen you need to find the wi-fi shortcut on the taskbar. If you click on it, a dialog box for managing networks will appear. To connect, you need to select a network and then click “Connect”.

There are times when the system is password protected and asks you to enter it. The system will not be able to connect to the access point until the password is entered. Subject to availability open point access, the system connects automatically.

The whole process is considered wifi settings on a laptop.

Once you have carried out all these manipulations, you will not have to do them constantly. But there were cases that for some reason wifi reasons won't want to connect. Often solving connection problems comes down to pressing hotkey and enable the desired option. Therefore, if the laptop stops connecting to the Internet, the first thing you need to do is check whether it is turned on.

The laptop uses a lot of energy to maintain an Internet connection. Therefore, it often happens that wi-fi stops working due to the use of economy mode.

External obstacles

It is worth remembering that if the Internet suddenly stops working, the reason may not only be present in the laptop. Wifi depends on external factors, because the radio signal can be weakened by exposure external environment. Walls, ceilings, floors, and other obstacles weaken the access point signal and the client device signal. The system always displays the signal level in the form of bars. How stronger signal- the more sticks. The signal at 1-2 short points is quite weak and often because of this it is not possible to use the Internet. It happens that the system does not see the signal at all.

If the laptop does not see WiFi, do not be upset, the problem is often very minor. By following the above recommendations, you can easily learn how to correct errors. And the laptop will always be reliably connected to the Internet.
