Today it is difficult to imagine operating a laptop or any other portable device without Internet access. Most often, the connection to the World Wide Web is carried out wirelessly - using the Wi-Fi network of the router. However, it is not uncommon for a user to have various kinds of problems when trying to get to the coveted Internet. One of them may be that the laptop does not see the Wi-Fi network. Let's consider the probable causes of such malfunctions. At the same time, we will leave out of brackets very similar cases when a laptop finds a Wi-Fi, but cannot connect to it, or it connects, but the Internet still does not work.
Most of the situations in which the problem we are concerned with 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 does my laptop 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 is 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 has "On" and "Off" modes. So, you need to make sure that the Wi-Fi module is currently active on your laptop. 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 activated. Usually a combination of a special key is used for this. Fn and one of the range function buttons F1-F12... Which of the system keys is responsible for turning on the wireless module, you can find out by the corresponding icon printed on it.
On laptops of some manufacturers, the Wi-Fi module is turned on / off 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 on, proceed to the next step.
What is the status of the wireless connection in Windows
At this stage, you need to check the connection status in the operating system itself. To do this, go to Control Panel - Network and Sharing Center - Change adapter settings.
We find a wireless connection here 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 the "Enable" item in the menu that appears.
After that, the icon in the system tray (notification area) should change.
Are the drivers for the Wi-Fi module of the laptop installed?
To check for the presence and correctness of the installation of the 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 adapter name and selecting the "Properties" line. On the "General" tab, the "Device Status" field should read "The device is operating normally."
The "Driver" tab allows you to perform various manipulations with drivers - update, rollback or delete. If you don't have the software you need, you can find it 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, 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 common reason for this metamorphosis is that your laptop is too far from the desired Wi-Fi signal source. Despite the fact that modern routers have a fairly large coverage area, reception may be unstable in some corners 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 site.
And yet, in most cases, problems with detecting the 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 signal quality. Let's take as an example. Let's go to its admin panel and select the section Wireless - Wireless Settings.
Immediately make sure that there are check marks next to the items "Enable wireless broadcasting" and "Enable SSID broadcasting" (the indicator on the router itself will signal the working state of the Wi-Fi network).
Now let's pay attention to the most important parameter - the Wi-Fi network channel. In Russia, 13 channels are used, but only a few of them may be optimal (least loaded) for you. It all depends on what channels nearby routers use. Try setting a static value (except 12 and 13) or Auto mode.
Restart your router and check if the laptop can now see the target Wi-Fi network.
If that doesn't help, try experimenting with the wi-fi parameters - change the channels, network name, adjust the filter by MAC addresses. As a last resort, you can reset the router to factory settings.
This is a very common problem considering that many internet users still use desktop computers. Naturally, most often, after a Wi-Fi router appears in the house, they try to connect a desktop stationary computer to a router. network cable(aka network cable, ethernet). Fortunately, most modern Wi-Fi routers have two or more LAN ports, usually marked in yellow. Actually, they are designed to connect devices to the Internet via cable. With such a connection, unexpected problems may arise, especially if the user tampered with the network settings of the computer. Also, if everything works over Wi-Fi, then it makes no sense to sin on the settings of the router. The reasons that a computer does not see the router on the cable, not so much. How to solve this problem, read below.The computer does not see the router via the cable, but everything works via Wi-Fi
We list the most likely causes through which a desktop stationary computer does not see the Internet via a cable through a router.Physical problems:
- Router port not working
- Network cable does not work
- Computer port not working
Software problems:
- Network card disabled by software
- Incorrect operation of the computer network card driver
- Antivirus blocking the connection
- Incorrect wireless settings
Physical problems
If the devices connected via Wi-Fi also do not work, then obviously the reason must be looked for either on the side of the Internet provider, or in the router itself. First of all, you should call the technical support service of the company that provides you with the Internet. After making sure that there are no problems on the provider's side, you can proceed to further verification. Pay attention to the indicator lights on your Wi-Fi router. A non-working router may be indicated by both the absence of indication at all, and the glow of only the power indication lamp (Power).If more than one indicator light is on on the router, then you can continue the test. Each indicator light is marked with an icon that indicates its purpose. For example, the "Power" icon is known to everyone and is used everywhere, as well as the Wi-Fi icon is generally understood. The numbers indicate the operation indicators of the LAN ports, these ports are used to connect the router with computers, smart TVs, etc. If there is electrical activity in the network cable connected to the LAN port of the router, the corresponding indicator will give light signals.
The lack of physical connection may indicate if you connected to the router with a network cable, and the indicator lamp of the corresponding port on the router is off. Try switching the cable to a different LAN port of the router. It happens that one LAN router port is not working(burned out), but the overall performance of the router is preserved. If, and this did not change the situation, then the reason is not in the burnt out connector.
The next step is to check the LAN cable itself (network cable). Plug both ends of the cable into the LAN connectors of the router for a few seconds. You will not be able to check the quality of the cable connection, but the indicators will not light up if network cable does not work... By the way, this method of connecting the cable should only be used to test its operability, as this leads to the router freezing as a result of "loopback".
If, having “looped” the cable, we saw that the indicators of the corresponding ports of the router finally lit up, then the suspicion falls on your computer itself.
First of all, on the computer, you should check if the local network connection is disabled ( software disabled network card). Take Windows XP, 7, 8, 10 for example.
XP path
Start - Control Panel - Network Connections - Local Area Connection.
Path for Windows 7, 8, 10
Start (Settings for Windows 8) - Control Panel - Network and Sharing Center - Change adapter settings - Local Area Connection.
The local area network connection can turn off by itself if there is no Internet connection, if this option is selected in the management of power settings. Moreover, you may not find a local network connection at all in the specified location, this indicates the need to install drivers on the network card.
If a red cross is drawn on the LAN connection, then computer port not working given the previous checks.
Software problems
If the indicator lights are on, according to the included LAN cables, then there is a physical connection, and the problem should be looked for in the computer settings or incorrect operation of the software.In order to exclude incorrect operation of the network card driver, go to device manager and see how the network card works. It is possible that there are errors in her work. In this case, you can update the driver of the network card.
In order to exclude blocking the connection by antivirus turn it off for a while and try to go online.
The last and one of the most important checks is to check the automatic receipt of the IP address in order to exclude incorrect wireless settings.
For Windows XP, click "Start", "Control Panel", "Network Connections", find the "Local Area Connection" icon ("Wireless Network Connection"), right-click on the icon, select "Properties" in the drop-down menu , in the window that opens, select "Internet Protocol TCP / IP" in the list so that the line is highlighted in color, and click the "Properties" button below the list. In the window that opens, make sure that "Obtain an IP address automatically" and "Obtain a DNS server address automatically" are selected, if not, select.
For Windows 7,8,10 click "Start" (or gear "Settings" for 8), "Control Panel", "Network and Internet", "Network and Sharing Center", "Change adapter settings" find the icon "Local network connection" ("Wireless network connection"), right-click on the icon, in the drop-down menu, select "Properties", in the window that opens, select "Internet Protocol version 4 (TCP / IPv4)" in the list so that the line is highlighted in color, and press the "Properties" button below the list. In the window that opens, make sure that "Obtain an IP address automatically" and "Obtain a DNS server address automatically" are selected, if not, select.
At least one of the listed recipes should solve your problem. If the problem persists, contact a specialist. As a rule, this is done by the same service centers that repair computers. Still, I hope that you were able to solve your problems, with little blood, with the help of this article.
A fairly common problem for owners of laptops with Windows 7 or Windows 8 (8.1) - at one point in the notification area, instead of the usual wireless Wi-Fi connection icon, a red cross is displayed, and when you hover over it, a message stating that no is displayed.
At the same time, in most cases, this happens on a completely working laptop - yesterday, perhaps you successfully connected to an access point on it at home, and today this is the situation. The reasons for this behavior may be different, but in general terms - the operating system believes that the Wi-Fi adapter is turned off, and therefore reports that there are no available connections. And now about the ways to fix it.
If the wireless network was working and now there are no available connections
If everything worked recently and now you have a problem, try the methods below in order. And if these options have already been tested, go to the seventh point, from which we will begin to describe in detail (because everything is not so simple there for novice computer users).
7. Remove the wireless Wi-Fi adapter from the device manager, reinstall it
In order to launch the dispatcher, 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, note if there is an "Enable" item (if there is, turn it on and do not do everything else that is described here, the inscription no available connections should disappear) and if not, select "Delete".
After the device is removed from the system, select "Action" - "Update hardware configuration" in the device manager menu. The wireless adapter will be found again, the drivers will be installed on it and, possibly, everything will work.
8. Check if the "WLAN Auto Config" service is enabled in Windows
In order to do this, go to the Windows control panel, select the "Administrative Tools" - "Services" item, find "WLAN Autoconfiguration" in the list of services and, if you see "Disabled" in its parameters, double-click on it and in the field Set the "Startup type" 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.
Hopefully, one of these methods will help you solve the problem when Windows says there are no Wi-Fi connections available.
The misunderstanding, which we will touch upon in our article, is increasingly troubling users of laptops connected to a wireless network. This misunderstanding is of a technical nature - the essence of the problem is the unexpected failure of the built-in or external router to receive and transmit data.
In this case, the network icon in the tray takes on a characteristic form - a ladder crossed out with a red cross - and when you hover over this cross, a message appears stating that there are supposedly no available connections in the Windows 7 system. This network behavior is a complete surprise to the user. We will teach you how to deal with this problem, but for now, drawing your attention to the fact that it often appears immediately after reinstalling the operating system. It may very well be that the reason for the network failure is the incorrect installation of drivers or the installation of drivers that are not quite suitable for your adapter model.
In this case, find out the model of your adapter and download the latest drivers for it. To do this, go to the laptop manufacturer's website - there they will probably be found. Download and install everything that will be offered to you. The fact is that in addition to the drivers necessary to ensure the operation of the network, drivers may also be required to support the function keys.
Many laptops use the "Fn" type function keys to control the adapter. If you do not use these keys, then managing the adapter turns into a hassle. The so-called flight mode is also activated by the keys. Without installing the appropriate programs, you lose most of the functionality. No wonder the WiFi module starts to behave strangely.
First attempts to fix the problem
To begin with, you can suggest trying the following actions:
- Restarting the router sometimes helps. To reset, simply unplug the power cord and plug it back in.
- Call the standard Windows diagnostic tool from the context menu of the connection icon.
- Sometimes the hardware WiFi switch on the laptop panel turns off. Check its condition.
- For this, you can try to run the service utility supplied by some computer manufacturers along with the drivers.
- Go to the "Network Connections" section of the control panel. Check if the wireless icon is active. If not, activate it from the context menu.
- Check the drivers again.
These activities are supposed to liven up your grid. However, this may not happen. In this case, follow our further recommendations.
Device Manager - Help
Like any device on a computer, the wireless adapter is registered in a Windows snap-in called Device Manager. You can access the dispatcher in different ways:
- Right-click on the My Computer icon. In the context menu, select the "Properties" item. In the window that opens, select the "Hardware" tab and click on the "Device Manager" button.
- And you can do otherwise. Without further ado, call the Run command window and enter devmgmt.msc in the command field - this is the name of the snap-in. The "Run" window itself is called either with the mouse from the "Start" menu, or with a group of keys "Win" + "R".
As a result, a dispatcher window will open, something like the one in the figure:
- Go to the node "network adapters".
- Expand this node.
- Find a device in its list whose name includes the word "Wireless" - this is a wireless adapter.
- Then right-click on its name and select "Delete".
- Then go to the main menu of the dispatcher window.
- And in the item "Actions" click on the item "Update hardware configuration".
If the network is still unavailable after that, try digging around in the system services settings.
Automatic WLAN Configuration Service
The service in question may also be responsible for the problem. It is located in the same place as all other Windows services, at "Control Panel" => "Administrative Tools" => "Services". Look for the "WLAN autoconfiguration" service in the list and find out if it is running. To do this, right-click on the service name and select properties in the context menu that opens. A window similar to the one shown below will open:
Make sure the Startup Type is set to Automatic. If this is not the case, then set this parameter, and then restart the service by first clicking on the "Stop" button, and then on the "Start" button. Save the changes made by closing the window by clicking the "Ok" button.
If everything is done correctly, then the wireless network should become active. If this is not the case, then it is worth looking for other reasons for its inoperability - it may be the matter in the equipment itself.
Technique, especially computer technology, can sometimes behave extremely capriciously and present various surprises. Yesterday you could use your laptop without any problems, go online using your home wireless connection, receive and send hundreds of files and photos, use social networks. And today there is no Internet connection, and in a place where yesterday there was not a single error in the system tray, a mysterious message is glowing: "No available connections." And what to do in such a situation is not entirely clear. We will try to analyze the causes of such a problem in as much detail as possible and talk about the most effective ways to solve it.
First, we turn to those who have encountered a similar problem after buying a brand new laptop or have just reinstalled Windows. If in one of these situations on your laptop you see the message: "No available connections", then most likely there is a problem with the network driver, which may easily be missing from the system after reinstalling Windows. Another reason in laptops of various models may be a mechanically disabled Wi-Fi adapter. How to understand which of the two situations became the primary source of the problem in your case, you will learn from the instructions below.
If a Windows laptop reported connection problems extremely unexpectedly, and everything was fine yesterday, there may be several more problems, and we will tell you about each of them today.
Any device can experience difficulties in work and even freeze, like Windows sometimes freezes. Since a router that distributes a Wi-Fi signal is, in fact, the same computer with an operating system and a processor, it can stop working, or it can freeze too. At the same time, a working indication on its body can mislead the user and create the appearance of normal operation of the device, but no signal comes from it at this moment.
The display on the device does not always indicate network problems
In order to return the router to its normal operating state, you need to unplug it from the outlet, wait a few seconds (7-10) and turn it back on. After giving the device a minute to turn on and start all systems, try again to check for available networks on your laptop.
If you receive a Wi-Fi signal directly from your provider, contact support and describe the situation, mentioning that you have no available connections. The operator will be able to remotely reboot their equipment.
Problem with a disabled network adapter
Please note that many models of modern Windows laptops include a mechanical activation and deactivation of the Wi-Fi function. This saves battery power. Find the toggle switch on the ends of your laptop that is responsible for turning on the wireless adapter, and turn it on. If such a toggle switch is not provided, then a special key at the top of the keyboard with the image of a wireless signal can help you. In the event that there is no such button on the keyboard, then, probably, the manufacturer has provided a certain key combination. Most often, this is the Fn function key and the F2 or F3 buttons. Please refer to the specific model manual for this information.
After turning on the wireless adapter in this way, try searching for available connections again.
Problem in software disabled network adapter
Also, the Wi-Fi adapter in your laptop can be deactivated in Windows itself programmatically. To enable it and repeat attempts to find available networks, you need to launch the Windows Control Panel, go to the Network and Sharing Center, and then in the column located on the left side of the open window, click on the link "Change adapter settings".
You will see information about all the network adapters and connections contained in your laptop. Find "Wireless Connection" and enable it using the right-click menu.
After that, also try to find available Wi-Fi networks using the system tray icon. Perhaps the problem you are facing has been resolved and then you will see the available network. But it may well happen that the adapter refuses to turn on, the items in the context menu after pressing the right mouse button will turn out to be inactive, or the adapter turned on, but still does not see available Wi-Fi networks. In this case, proceed to the next paragraphs of our instructions.
The problem is the incorrect operation of the driver or its absence
A specialized program is responsible for the operation of each function of the Windows operating system. And a system program called a driver is responsible for the operation of each component in your laptop. It is she who corrects the operation of devices, gives them system commands and monitors the correct execution of these very commands. If the system does not have a driver or a version of it is installed that does not quite match this network adapter, you may also experience difficulties finding networks, connecting them and transferring data.
There may be situations in which the driver was installed, configured, and the system worked quite correctly, but after another simple reboot, you saw the message "No available connections", and you cannot go online. Probably, your operating system has a program that is responsible for automatically updating and installing drivers for various devices, and after a reboot, a driver version that does not match the network adapter model was installed, or a test assembly that does not work as expected.
To update and install drivers for various components of your laptop, we always recommend using the two most reliable sources - the website of the manufacturer of the computer itself or the website of the manufacturers of its individual components.
Go to the manufacturer's website, download the latest version of the software for the network adapter, making sure that it is designed for the same version of Windows that is installed in your laptop. After that, complete the installation and restart your PC. To avoid problems when installing a new driver, we recommend that you first uninstall the existing one by finding your network adapter in the Windows Device Manager, right-clicking on its name and going to Properties> Driver> Uninstall.
After installing the latest driver and restarting the PC, re-search for available networks to make sure all systems are working correctly and to connect to the network.
The problem is incorrect system configuration or violation of registry settings
When all the previous methods have been tried, but none of them gave the desired result, you can resort to really serious and deep troubleshooting and system malfunctions. This is especially recommended for those users who are sure that until the moment of failure, the network adapter performed its functions correctly and you did not interfere with its operation. In this case, the reason could be third-party programs and applications, their installation or removal, reconfiguration of certain parts of the system. Any of these actions might not have the best effect on the network operation in your laptop, and then it is worth resorting to the following actions.
If you have a backup of your system created using specialized software, try restoring the system to the state in which it was at the time of the last checkpoint. This procedure will undo all the latest changes in the system and return it exactly to the state in which your network adapter performed all its functions correctly. Please note that restoring a copy that is too old can deprive you of a large number of settings, programs and parameters that have appeared in the system recently.
If you do not have such a backup, refer to the built-in Windows recovery system, which creates checkpoints during some key procedures performed with the computer. To do this, open the "Properties of your computer" by right-clicking on the "My Computer" icon on the desktop, and then find the "System Protection" item in the column located on the left in the window that opens. Press the "Restore" button and select the system state point that should be restored on your PC.
If system protection was disabled and checkpoints were not created, we recommend that you resort to a full OS scan and check the integrity of Windows files. For this, there is a special service that can be started using the command line.
Open a command prompt, manually enter the sfc / scannow command in it and press Enter on the keyboard. If the system contains corrupted files or some parts of the registry are not working in the most correct way, the scan service will try to detect them and restore them to their original state. This procedure can take quite a long time, and upon completion, a mandatory system reboot will be required.
As a rule, troubleshooting when there are no available connections does not require serious skills and is rarely a reason to contact a service center. You can restore the wireless adapter to work using one of the methods provided here. If the desired result cannot be achieved using one of the instructions, it may be necessary to combine several methods at the same time. It depends directly on the specific laptop model, its configuration and system parameters.
Quite often, for many users of computers running the seventh and eighth versions of Windows, it may happen that a cross appears instead of the usual wireless connection icon, indicating that there are no available connections.
And this happens mainly on a fully working computer. At the same time, up to
At this point everything worked fine and it was possible to connect to the Internet, but now this is not possible. This problem can occur for various reasons, however, it all comes down to the fact that the operating system does not see the Wi-Fi module and considers it turned off, as a result of which it displays a message about the absence of connections. But you can fix this problem. There are several methods for this.
If Wi-Fi was not previously used on this laptop, or Windows was reinstalled
If a wireless connection has never been used on a laptop, and now a Wi-Fi router appears and you need to connect to it, but this problem arises, then you need to search the Internet for tips on why Wi-Fi does not work on a laptop.
The main thing that needs to be done in this case is to install all the necessary drivers that need to be downloaded from the manufacturer's official resource, but not the driver-pack. At the same time, it is necessary to download drivers not only for the Wi-Fi module, but also to maintain the performance of the laptop keys, which are designed to turn on the wireless adapter.
If the wireless network was working and now there are no connections available
If everything worked fine up to this point, and then this problem suddenly appeared, then it is necessary to check in turn all the methods described below. You can try to disconnect the router from the electrical network, and then turn it back on. In addition, you should try using the "Troubleshooting" section that appears when you click on the Wi-Fi connection icon with a cross.
In addition, you need to check whether Wi-Fi is turned on on the laptop, if any, and also whether it turned out to be turned on using the function keys. It is also worth visiting the proprietary Wi-Fi network management program, if available. In addition, you need to make sure that the wireless connection is in the list of connections.
In the "eight", in addition to all the described methods, you should go to the "Control Panel" and select "Options". In this section, you need to click on "Change PC settings", and then select "Network" or "Wireless", depending on the version. Here you need to check that all modules are active. In 8.1 you need to check if
whether the "Airplane mode" item is enabled.
In addition, you should visit the official resource of the laptop manufacturer and download the drivers for the Wi-Fi module from it and install them. It is worth doing, even if such drivers are already available, it is still worth trying.
If after doing all this, nothing has changed, then you can try another method. It is not the easiest one, so it will not be so easy for inexperienced users to complete it.
Remove the wireless Wi-Fi module from the device manager, reinstall it
To open the device manager, you need to press Win + R and register the devmgmt.msc command, after which you need to click OK. Then in it you need to go to "Network adapters". Here you need to right-click on the Wi-Fi module. It is worth checking that there is no "Enable" item in the context menu. If there is one, then you need to use it and not follow the steps described below. If this is not the case, then you need to select "Delete".
After removing the device from the operating system, in the device manager, select "Action" and click "Update hardware configuration". This will start the search for a Wi-Fi module, after which all the necessary drivers will be installed on it. Maybe after that everything will start working.
See if WLAN Auto Config is activated in Windows
To perform this method, you need to go to the "Control Panel". In this section, you need to select "Administration". After that you need to click on "Services". In this section, you need to find the "WLAN auto-configuration" service. If it says "Disabled", then you need to double-click on it and set "Automatic" in the "Startup type" line. After that, you need to click "Run".
Hello everyone! For many years the life of a modern person has been inextricably linked with the worldwide Internet. And with the increase in production and the introduction of small wearable electronics into life, wireless data transmission technologies have become widespread. A person, simply put, loses touch with the world when his laptop cannot connect to an access point. Therefore, today we will try to figure out why the laptop does not see the wifi network and what to do in such cases?
Typical causes and their elimination
Let's see for ourselves the possible reasons, after which we will find a solution to the problems with connecting to wi fi.
Hardware problem
Before looking for a software problem, it is worth checking if there are any physical malfunctions, otherwise there are cases when the laptop has purely mechanical damage or shortcomings. Therefore, if they write to you that there are no available connections, then first of all look at:
- whether the desired access point can be seen by any other device, for example, your smartphone (an inscription on a sign, a sticker or a friend's story does not yet guarantee that the equipment that provides data transfer via Wi-Fi is turned on and functioning);
- whether the required module is installed in the laptop (this is more related to purchased second-hand PCs, where the seller's dishonesty is possible), usually this is a small board that can be accessed from the back cover. In the same place, you should check whether the two output wires are fixed to the antenna;
- whether the wireless module is physically enabled (on many older laptop models this mode is activated by a special switch on the case), for this you need to carefully examine the case for buttons and switches.
- The problem with the wifi router. If the laptop sees all networks except yours, then check if the router is connected to the network, and if the main wire from the provider is included in it. Sometimes it happens that it is only half turned on. But in any case, check if all the required lights are on on the router. But the truth is this is purely about your network. And if he does not see anyone at all, then that is another question.
Software problems
Having satisfied that the devices are present and functioning in the laptop and the access point, check if Wi-Fi is enabled by the operating system. In the newest versions of Windows, there is an item called "Airplane mode", the activation of which blocks all connections. Therefore, we disable it. Usually this item is located at the right edge of the Quick Launch bar.
Almost all models use the FN key combination and the antenna image on the keyboard. Often, an additional LED is installed on such a button, which indicates the activity of the wireless module. Sometimes, for this combination to function, you need to install special software. You can find it on the manufacturer's website or on the included CD.
If the problem persists, look further. In "", tab " Network and Network Connections", We find the item" Change adapter settings»And look for an active or inactive wireless connection there (they differ from a wired connection by their name and icon).
After that, it will be easy to turn on the icon in the operating mode. If there is an inscription "Disabled", select it with the right mouse button, in the menu that appears, select "Connect". If there is no such item, then move on.
Also inside " Control panels"Find" Device Manager"And look in the branch" Network adapters»Items containing the word Wireless or wireless (but not Bluetooth). The presence of icons next to them (a cross or an exclamation mark) may indicate problems with the driver, the program that controls the wireless module. Try to click on it with the right mouse button, then poke on "Enable". If it doesn't work, then move on.
Installing (reinstalling) a device driver
Sometimes, your adapter just can't route correctly, so download the wifi driver and install it.
Software for the correct functioning of all parts of the laptop are present on the CD-ROM included in the kit, in a separate folder on the hard disk (DRIVERS). If there is no disc, then they can be downloaded from the manufacturer's website. After starting which, the process of installing the necessary files into the system will take place, upon completion, you should restart the computer.
It is worth noting that often installing only the required driver may not solve the problem, so you should install the entire software package. This is due to the interconnection of different hardware in the laptop.
We fight viruses
As strange as it may sound, but one of the reasons why the laptop does not see the available networks, these are viruses. Therefore, it will make sense to go through some kind of antivirus, either like Dr Web Cureit or Kasperskiy Removal tools.
Wi-Fi signal blocking
The very last and most incredible item. The technique that blocks wireless signals quickly got from fantasy to stores, and thanks to the "Chinese manufacturer" it became available to anyone. Both security services and just a disgruntled neighbor can temporarily block all Wi-Fi signals. You can determine this option simply by moving the PC to another location.
Theoretically, such blocking can be used by fraudsters to intercept data, credentials of computers on a Wi-Fi network. In practice, this type of lack of communication is very rare at the moment.
In conclusion, I must say. If none of the above actions helped, then most likely there is a breakdown of the personal computer, the correction of which is better to entrust to professionals.
But if you really contact someone, then only through friends and acquaintances, as well as in specialized services. They already know in person how to fix and configure everything correctly. But just never contact the masters for ads like "I live nearby, I will come quickly." I wrote more about this in. Read it. I am sure you will like it.
Well, this is where I end my article. I really hope she helped you. If this is true, then be sure to subscribe to my blog updates, and also share information with your friends on social networks. Good luck to you. Bye Bye!

Hello everyone! As I said, I work with sis. as an administrator in an Internet cafe, and of course I deal with computer equipment and local networks.
So, recently my Aunt called me and asked to come and set up the D-link wi fi router, which she just bought in the store. I come, set it up, everything is in order Aunt is happy Surfing the Internet on a netbook on Wi-Fi
But it was not there! The next day it calls and says the phone does not see wi fi and the laptop does not see wi fi! It only finds some kind of neighboring access points and that's it, well, I come, I think let me check the router at home, take it and take it home, connect everything okay everything works! I'm in shock =) I come back to Aunt and connect it again does not work ... So I went to see a friend, he also worked ... Then I started rummaging through the settings of the router, but I could not find anything.
Then my Uncle comes into the room and says that the security company from below can their equipment be blocking? I think for sure! the problem is in him, you won't see Aunt wifa And I'm leaving ...
But a few days later I got a call from another 1 person with an anthological problem! And for a long time I found a solution to this problem! In this article, I will now explain everything step by step how to solve such a problem!
Nowadays, a Wi-fi router has appeared in almost every apartment, and when you turn on the router in a neighboring apartment, you may lose Wi-fi Internet (everything will work fine through the cable in the computer).
Solution
I'll show you the example of a wi fi router router D-link DIR 300
The problem was that when configuring the Wireles router, the channel is automatically selected by default (auto), shown in the screenshot:
We need to go to the router (web interface), if you did not change the local IP address when setting up the router, then you have it by default 192.168.0.1 , we write this IP in the browser and go to the Web interface of the router.
We go to the item as in the screenshot and change the channel, set a number different from the one set automatically (I always hit the first time and everything started working).
Now the wi fi network finds any of your devices!
Here is such a simple solution to this problem.
If you have questions, maybe you have a different router firmware and you cannot find this setting, write in the comments, I will help you.
