Welcome friends. In this note, consider why the laptop may not see the Wi-Fi network. To begin with, it is necessary to understand (albeit shortly), what is Wi-Fi, what is his principle of operation and, that it is usually required for this.
So, if you say an affordable language, then wi-Fi is nothing but a wireless way to communicate digital devices. It is important to understand that with the help of it it is not necessary to go immediately on the Internet, it is just a way to build wireless networks (such as bluetooth).
In order to enter the Internet, you need this Wi-Fi network to be connected to a router (special modem), which is already in turn and exits the global web (via a telephone, network cable or in any other way).
From this it follows - if there is a Wi-Fi-Fi in your device (laptop, telephone, tablet), then it does not mean that it will connect to the Internet now (maybe someone will seem obvious, but some users can think exactly ).
2 Main situations where you can not connect to Wi-Fi
- Cause in your device
- The problem in the Wi-Fi network (that is, in the modem on which this network is created)
In order to exclude malfunctions in your laptop you need to connect to the available Wi-Fi network from another device, for example, from your friend's phone. For this, as usual, take a smartphone from him (tablet, "beech"), search for available Wi-Fi networks and connect to the desired one.
As a result, if your router is configured correctly, the friend's smartphone has connected immediately and without problems, then you should look for the cause in your device (about it just below).
In the second case, you are sitting one (or with the company) and cannot connect to Wi-Fi network, for example, in a public place. It is correct, it may simply just turned 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 (yours, not a neighbor), then you need to restart it or reconfigure it.
That is, the first thing you need to decide where the fault, and then deepen into its solution.
Reasons why a laptop may not see Wi-Fi
Now consider more in-depth the highlights of why the network is not connected to the Wi-Fi:
- To begin with, it is worth noting whether Wi-Fi is enabled in Buckka. It is checked easily, at the bottom of the clock, press the corresponding icon. If no available networks appear there, then, most likely it is disabled.
- Connected connection. It can be most often due to modem errors. You can simply reboot it or reconfigure. To do this, just look at your modem and find the Wi-Fi indicator - it should burn.
- Is the driver installed and what is its version on the laptop. Very often, if the "beech" new or on it was reinstalled by the operating system, after installing the required driver on Wi-Fi. If this is not done, then enter the network will not succeed.
- Wi-Fi stopped working on the "laptop". The reason may be a breakdown of the appropriate adapter inside the device. Here is only repair with its replacement.
- Ended money "On the Internet". In such a situation, it is necessary to go on the Internet on the Internet. You just need to put money on the score and the problem will be solved.
Conclusion
As you can see, the reasons may be quite a lot, we considered only the simplest and most popular. It is not necessary to refer to simple ways of solving the type - checking funds on the account or restarting the laptop, very often they are helping to solve the current problem.
It is worth starting with the information provided above, and then go to a deeper and individual decisions of your question. On this we will finish the decision of the issue, why the laptop may not see the Wi-Fi network, which is primarily in such a situation. Thank you for your attention if questions appeared, then write them in the comments.
Today it is difficult to imagine the operation of a laptop or any other portable device without access to the Internet. Most often, the connection to the World Wide Web is carried out by wireless - using the Wi-Fi network of the router. However, often at the user when you try to get to the lined Internet there are various kinds of problems. One of them can be that the laptop does not see the Wi-Fi network. Consider the probable reasons for the appearance of such faults. At the same time, leave the braces very similar occasion when the laptop finds Wi-Fi, but it cannot connect to it, or connects, but the Internet does not work anyway.
Most situations in which the problem affected by us can be divided into two categories:
- The laptop does not see any Wi-Fi network in any other, although they are definitely and detected by other devices;
- The laptop does not find specifically your wireless network, but sees the surrounding Wi-Fi networks.
Based on this gradation, and we will identify the cause of the problem.
Why the laptop does not see any Wi-Fi network
Such a malfunction is almost 100% connected with the client device itself and its settings. Let's try in step by step mode to check several main points that can affect the visibility of wireless networks.
Wi-Fi module included on your laptop
Any laptop computer is equipped with a wireless adapter, providing the ability to search for Wi-Fi networks and establish connections with them. Typically, this module provides "On" and "Off" modes. So, you need to make sure that the Wi-Fi portable computer is currently active. This will indicate the corresponding light indicator, the location of which depends on the laptop model.
If the module is turned off, it must be activated. Usually for this, a combination of a special key is used. FN. and one of the functional ranges of the range F1-F12.. What exactly which of the system keys is responsible for turning on the wireless module, you can learn from the corresponding icon applied to it.
On laptops of some manufacturers, the Wi-Fi module is switched on / off with a two-position toggle switch or a separate button.
If, when the Wi-Fi enabled, the laptop adapter still does not detect wireless networks, go to the next step.
What is the status of a wireless connection in Windows
At this stage it is necessary to check the connection status in the operating system itself. For this go to Control Panel - Network Management Center and Shared Access - Change Adapter Parameters.
We find a wireless connection here and check its activity. If the icon is highlighted, it means that the connection is turned on, otherwise it must be turned on.
Click right-click on the icon and in the menu that appears, select "Enable".
After that, the icon in the system tray (notification area) should change.
Are drivers for Wi-Fi laptop module
To check the availability and correctness of the installation of the network adapter drivers, go in series along the way Control Panel - System - Device Manager. In the list we find the item "Network Adapters" and deploy it.
If there are no exclamation marks next to the device, then most likely the drivers are installed correctly. Make sure this by clicking the right mouse button by the name of the adapter and selecting the "Properties" string. On the General tab, the "Device Status" field should be written "The device works fine."
The "Driver" tab allows you to produce different manipulations with drivers - update, roll back or delete. In the absence of the necessary software, it can be found on the Internet.
In theory, if there is no questions in all of the above items, the laptop should easily see the nearby Wi-Fi network. If this does not happen, then malfunctions are possible with the adapter of a laptop computer.
The laptop does not detect the network of my router, but sees others
The most banal cause of such a metamorphosis - your laptop is too far from the desired source of Wi-Fi signal. Despite the fact that modern routers have a fairly extensive coverage area, in some corners of your home or apartment a reception may be unstable. In such a situation, it is necessary to properly place the router, so that all consumers were in the reach zone. About, you can find out on the pages of our site.
And yet, in most cases, problems with the detection of a wireless network of one particular router are associated with its incorrect configuration. Let's try to figure out which Wi-Fi settings can significantly affect the quality of the signal. For example, take. Go to his administrative panel and choose the section Wireless Mode - Wireless Settings.
Immediately make sure that the checkboxes are located next to the items "Enable Wireless Broadcasting" and "Enable SSID Broadcast" (the Wi-Fi operating status is displayed on the router itself).
Now pay attention to the most important parameter - the Wi-Fi network channel. Russia uses 13 channels, but only a few of them can be optimal (the least downloaded). It all depends on which channels involve nearby routers. Try setting static value (except 12 and 13) or AUTO mode.
Restart the router and check if the laptop is now the target Wi-Fi network.
If it did not help, try to experiment with the Wi-Fi parameters - change the channels, the network name, adjust the filter by MAC addresses. In extreme cases, you can reset the settings of the router to factory.
Why does the laptop sees Wi-Fi? Access points are almost everywhere. But there is no possibility to connect to the Internet. Because the laptop as if "blind". It seems that everything is done correctly.
Made the necessary settings. And the computer is deaf. Why?
Laptop does not detect wireless Internet: why?
Many faced such a problem. The most offensive thing is that the failure could have been involved on any plot, any link. Popular routers, which people use today to connect, are configured approximately equally. Nute also requires certain actions, almost completely identical to all models.
Causes of non-operating wireless networks:
1) Your router is not configured to receive the signal, it is turned off for some reason, it began to bullure or hung;
2) the reason lies in the computer; The corresponding settings are not made, the hardware slider or the wireless connection button is disabled (it is usually located on the housing);
3) the Internet was not paid or the provider turned off for other reasons;
4) the host of the access point to which you are trying to connect unauthorized (without permission) blocks your connection;
5) Antivirus program blocks world wide web;
6) The IP address was not automatically entered.
There are a lot of reasons. Explain situations where the provider restricts your actions or you are trying to connect to "someone else's" no, we will not. In such cases, questions need to be solved with money or personal charm. And here all instructions are useless.
Search for solutions
Why doesn't the computer sees a flash drive? The reason may be in the computer, and in the flash drive. Also also with wireless Internet.
To solve the task, you need to classify it. In which site, a failure occurs?
1. The router does not receive a signal, not allowing the Internet.
2. The laptop is not connected to the signal transmission device.
3. The signal goes, the computer sees the network, but it is still impossible to enter the Internet. For some reason.
Problem number 1. Router does not work.
The easiest way to make sure its performance is to connect the laptop to it on the network cable. If everything is fine with the router, the Internet connection will happen.
External signs of the inoperability of the device:
a) "silent" the corresponding indicator on the housing;
b) None in the administrative panel in the WAN Internet Connection tab.
What can be done?
1. Turn off and turn on the router again (suddenly it hung).
2. Check if the router and network card are enabled.
3. Check the settings for connecting to the provider. If necessary, make them re-manually.
4. Call the provider and ask if everything is in order with the network.
Problem number 2. The laptop is not connected to the router.
The device receiving signal works. Other computers, smartphones, phones and the like see the router. And the specific computer does not see anything.
1. Check the network connection on the computer (in the Network Connections tab).
2. Check the settings of the router and laptop. Through the "Control Panel" we find the network interface responsible for connecting. The path to it in different versions of the operating system is different. But usually the adapter is signed as a "wireless network connection". We go to the "Properties" and find the Internet version protocol. We go again in "Properties" and check whether the IP address, the main gateway, the subnet mask is specified. Perhaps this data was not introduced at all. Then we introduce them (they are obtained from the router).
3. Check on the device case, is it turned on the corresponding button.
Problem number 3. The laptop sees the network, but the Internet does not work.
1. Re-install the Wi-Fi transmitter drivers (they are on the website of the laptop manufacturer).
2. Check the existence of a car in the "sleep mode". This setting often interferes. Therefore, the automatic transition to sleep mode must be disabled.
3. We make a Wi-Fi safe for a computer network. Perhaps the firewall perceives it as a threat, and therefore it does not allow. The procedure can be made through the "Network and Shared Access Center". Go there and just choose the necessary network.
Try to turn off the antivirus program for the check time. Perhaps the problem is in it. Any of these methods should help.
To date, portable devices are gaining increasingly popular compared to personal computers, and there are a number of reasons for this. Modern laptops, tablets and phones are not just compact in size. They support communication with the Internet via Wi-Fi, and this is important, because the Wi-Fi network today is quite widespread. It is available in cafes, restaurants, libraries, train stations and even public transport. All this is due to the Wi-Fi module exhibiting in portable devices. However, sometimes such a wireless communication is not entirely correct.
A little about Wi-Fi coverage
The Wi-Fi network is wireless and created based on IEEE-802.11. To date, the data transfer rate through this network can reach 600 MB / c. Wi-Fi coverage has a number of positive sides, namely:
- To connect to the phone, laptop or tablet, you do not need a cable. Thus, the amount of cash costs decreases.
- The owner of the phone, tablet or any other portable device is not limited to a certain place. Using the Internet can be anywhere where the user will only wish.
- Wi-Fi coverage without problems can be used by the owners of phones, tablets and smartphones.
- Despite the fact that the Wi-Fi network indoors is one, many users who have a telephone or tablet can simultaneously connect to it.
Causes of Wi-Fi Connections
About such a reason, as too much remoteness of the portable device from the point of connection, that is, the router is not worth mentioning. The main thing is to observe the required distance. However, if the laptop, the phone or tablet is located a few meters from the wireless router and there is no connection, then it has several reasons. So, here are the reasons:
- Old laptop models have a special small button on / off Wi-Fi connection. Therefore, it is worth checking that the connection is simply inclusive. In new models, you can use a combination of keys, for example, Fn and F2 to enable access to Wi-Fi. Additional help will provide device documentation.
- The following reason is damage to the drivers that ensure high-quality Wi-Fi module. The problem is easily solved by reinstalling drivers that can be downloaded using the manufacturer's official website. Other sites can offer low-quality products.
- Sometimes the adapter module does not work at all. This is caused by the lack of a special utility that allows you to control the wireless network. The utility can be found on the manufacturer's website, and install from the disk attached to the laptop kit.
- Sometimes a Wi-Fi connection is completely inaccessible. In view of the cases where all devices recognize the network, and one of the devices is not. In this situation, you first need to turn off the router for 10-30 seconds, and then turn it on again. Sometimes the problem occurs due to the unforeseen router settings fail. All you need is to reinstall it. In the current situation, the provider's support service will provide the highest quality assistance, because each provider has its own type of settings.
- It also happens that the signal is almost impossible, is characterized by a low level. At the same time, some devices recognize a Wi-Fi connection, but the connection is still impossible. This situation may occur if the router is quite far from the laptop, phone or tablet.
- Theoretically cause can be a Wi-Fi module breakdown in a laptop or any other device. At the same time, if the warranty is still valid, you can easily change the purchased goods. With the presence of an old device, the repair can be very expensive. Therefore, many are advised to acquire a Wi-Fi external adapter, which is priced quite accessible.
So it is important to remember that it is not enough to purchase a router, connect the corresponding cable to it and connect to the Wi-Fi network. A setting is required that best trust the master.
Hello, dear friends. As you probably understood from the title, I decided to raise a very serious and painful theme today, and try to figure out what to do when Wi-Fi does not work on a laptop, or a netbook and how to connect a laptop to a Wi-Fi router. By the way, it may not only be a laptop, or a netbook, it can still be an ordinary stationary computer with a Wi-Fi receiver. Large questions recently appear very much, mainly to the article.
Now we will try step by step to figure out what and why problems can appear when connecting a laptop to a wireless Wi-Fi network. We will also try to find a solution to this very popular and unpleasant problem with connecting to Wi-Fi, more precisely unsuccessful connection.
Most often, problems arise when it is not possible to turn on the Wi-Fi itself module on a laptop. And when Wi-Fi turns on, all the available networks laptop finds, but when you try to connect. It is necessary to check whether the driver is installed on the Wi-Fi adapter, whether Wi-Fi is enabled on a laptop, etc. Now we will do it.
I noticed that most often problems with the Wi-Fi connection are found in Windows 7. It is on this OS that a network error is very often appearing without access to the Internet, how to solve this problem I wrote in the article, the link to which is above. In fact, as practice shows, there can be a lot of reasons for this problem. And if there are many reasons, then there are many ways that you can force the laptop to connect to a Wi-Fi router.
But it is not always a laptop, a netbook, etc. It may be a problem at the point of access, that is, in a Wi-Fi router. And the first thing we need to do when you have a problem with connecting to Wi-Fi, it is to determine what cause, in a laptop, or in a Wi-Fi router. Now I will consider the problem with connecting to your own router. Because, if you fail to establish a connection to other Wi-Fi, then all claims to a neighbor, it most likely has problems :).
Who is to blame, laptop, or Wi-Fi router?
As I have already written above, you must first find the culprit. Before you make any settings on a laptop, or a Wi-Fi router, you need to understand what the problem is, because of which it is impossible to connect a laptop to Wi-Fi. You just can be configured that then you have to do and configure everything. The best way to determine in which device is hiding the problem, it is to try to connect another device, such as another laptop, tablet, or telephone to the router. A laptop on which there are problems with connecting to Wi-Fi, you need to try to connect to another wireless network.
I think you understand my thought. If your router other devices (best with a similar operating system) Will be connected without problems, then the problem is in a laptop. Read this article further, now let's try to decide.
Well, if problems with connecting to your network occur on other devices, and the "problem" laptop connects to other networks without any problems, then the problem means to configure the Wi-Fi router. See the article by, perhaps it is useful.
I will show on the example of a laptop that works on Windows 7. This is the most popular operating system on a melon moment.
I advise you to immediately pay attention to the icon that displays the Internet connection status. It is in the notification panel.
If the Internet connection status looks like this:
You need to start checking if the Wi-Fi drivers are installed and the Wi-Fi adapter is enabled.
Click right-click on "My computer" and choose "Properties". Select on the left "Device Manager".
In a new window, open the tab "Network adapters" and see if there is a device type Wireless Network Adapter. (you can be called differently). If this device is present, click on it right-click and select "Properties". Another window will open, make sure that it is written "The device works fine."
If you are all about the same way as I have above in the screenshot, it means everything is fine, the driver is installed. And if there are no Wireless Network Adapter devices and you have unidentified devices, go to the manufacturer's site of your laptop, download and install the driver on Wireless Network Adapter for your model.
More information about installing and updating the driver for a wireless adapter.
With drivers figured out.
Check whether Wi-Fi is enabled on a laptop
If the driver is installed, but the Wi-Fi module is disabled, the connection status will be the same:
Usually, the adapter of wireless networks on a laptop is turned on, but does not prevent check. Wi-Fi on laptops (netbooks) is usually turned on and disconnected by a key combination. On my ASUS K56CM.These are keys Fn + F2.. But although when you click on these keys, I have a message that the wireless adapters are turned on / disabled, but nothing happens. Look at your laptop key FN. and key with the image of a wireless network. Click them at the same time.
On some laptops there may be a special switch on the housing, which can be enabled, or disable Wi-Fi. For example on Toshiba Satellite L300. He looks like this:
Turn on, or turn off Wi-Fi wireless adapter in Windows 7
But the best way to check works, or there is no wireless network adapter, it goes to the network management center and see.
So on the notifications panel, press the right mouse button on the Internet connection status icon and choose "Network and Common Access Control Center".
Then select on the left.
Among connections are looking for "Wireless Network Connection". If everything is fine and Wi-Fi adapter is turned on, then it should look like this:
If the adapter is disabled, then it will look like the screenshot below. Click on it right-click and select "Enable".
The methods described above, we must do so that the status of the Internet connection on the notification panel was this:
This status means "No connection - there are available connections" - This means that the Wi-Fi adapter is enabled and there are available wireless networks for connecting.
If the connection status is this:
This means that Wi-Fi is on, but just a laptop does not see the networks available for connecting networks.
Error "Windows failed to connect to ..."
With a problem when a wireless network module is disabled, or it does not work at all. Now consider the case when the laptop finds available Wi-Fi network, but when you try to connect to Wi-Fi, it writes: "Windows failed to connect to ..."where, instead of points, the name of the network to which you want to connect.
If you have the status of connecting to the network, such as in the screenshot above (through one, network with a yellow icon), then click on it, and you will see a list of networks available for connection.
Select the necessary network, click on it, then click the Connect button.
If the set is password protected, then Windows will ask you to specify the password. Push the password from the network and click "OK".
And if everything is fine, then your laptop should connect to the Internet for a wireless connection. And the status of connecting to the Internet should look like this:
But it is at the time of connection that an error is very often "Windows cannot be connected to ...". 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 Wi-Fi Routher settings. It may be through the type of security and encryption that is installed on a Wi-Fi router, read more about it in the article. There may also be a problem with the distribution of IP addresses.
If you notice, then in the window with an error "Windows failed to connect to ..." It is possible to run "Troubleshooting", sin does not take advantage. Try running, somewhere heard that there are cases in which it helps :). And if seriously, sometimes it really helps. Windows will check the readiness of the wireless adapter, check the settings, etc. And if it can, it will eliminate the problem that prevents you from connecting to Wi-Fi.
Just restart the router, and then the laptop. Very often it helps.
Update
I noticed that in Windows this error appears when the settings that are saved on the computer for your network do not match the current network settings. I'll explain now.
For example, your laptop has been connected to Wi-Fi, it automatically connected to the network. But you took and changed the password, or the type of network encryption. Now the laptop tries to connect to the network, but the parameters do not match, so the error.
Enough, just delete the network on the computer and install the connection again. I wrote about it in the article
Conclusion
A large article turned out, and I hope that useful. For half a day, she wrote her, of course, there were still problems with the addition of screenshots to the site, but it seemed to decide.
I tried to collect all the necessary information that should help you solve the problem that occurs when the laptop is connected, or the netbook to Wi-Fi. If something forgot to write, then in the future I will definitely add an article, I will also be very grateful if you share the information in the comments that helped you solve the problem with connecting to a wireless network.
If you have any questions, ask them in the comments, we will try to figure out. Good luck!
