Quite often, many users of computers running the seventh and eighth Windows versions it may happen that instead of the usual icon wireless connection a cross appears, indicating that there are no connections available.
And this happens, basically, 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 there is no such possibility. 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 lack 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 the laptop has never used a wireless connection, and now a Wi-Fi router has appeared and you need to connect to it, but there is this problem, then you need to search the Internet for tips on why Wi-Fi does not work on a laptop.
The main thing to do in this case is to install all required drivers, which 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 wireless adapter.
If the wireless network was working, but now there are no connections available
If up to this point everything worked fine, and then this problem suddenly appeared, then you need to check all the methods described below in turn. You can try to disconnect the router from the electrical network, and then turn it back on. In addition, it is worth trying to use the "Troubleshooting" section, which appears when you click on the Wi-Fi connection icon with a cross.
In addition, you need to check whether Wi-Fi is enabled on the laptop, if any, and whether it was possible to turn it 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 "Settings". In this section, you need to click on "Change PC settings", and then select "Network" or " Wireless connection”, depending on the version. Here you need to check that all modules are active. In 8.1 you need to check if
whether the item "Airplane Mode" is enabled.
In addition, it is worth visiting official resource laptop manufacturer and download the drivers for the Wi-Fi module from it and install them. It's worth doing, even if such drivers are already available, it's still worth a try.
If after doing all this, nothing has changed, then you can try another way. It is not the easiest, so it will not be so easy for inexperienced users to complete it.
Delete wireless wifi module from device manager, install it again
To open the device manager, you must press Win + R and enter the command devmgmt.msc, after which you need to click OK. Then you need to go to "Network adapters" in it. Here you need to right-click on the Wi-Fi module. It is worth checking that context menu There was no "Enable" option. If there is one, then you need to use it and do not perform the actions described below. If not, then select "Delete".
After removing the device from the operating system, in the device manager, select "Action" and click "Update hardware configuration". This will start searching for the Wi-Fi module, after which all the necessary drivers will be installed on it. Maybe after that everything will work.
See if the WLAN AutoConfig service is enabled 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 AutoConfig 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".
These are all ways to solve Wi-Fi connection problems. Surely one of them can help. All of them are pretty simple. In addition, among them there are those that even novice users can use without harming the computer.
If on a laptop after pen Windows installation or just for no apparent reason, Wi-Fi does not work, writes that there are no available connections and shows a red cross on the connection icon, the material below describes several possible causes this problem and what to do to fix it.

No Wi-Fi connections available when laptop is turned on again
If you previously connected to Wi-Fi wireless networks on the same laptop, and now, without any actions with the drivers, without reinstalling Windows, you suddenly get a message that there are no connections available, this usually means that for some reason Wi-Fi Fi adapter turned off.
Here's what to look out for in order to try and fix the problem:
In general, this is usually possible options, which help fix the problem if it is not missing drivers, a recently reinstalled system, or some kind of hardware problem. If these options do not help, you can try the following solutions.
Just in case, also check if the Wi-Fi adapter was somehow accidentally disabled in Device Manager:
- Press the Win+R keys on your keyboard, type devmgmt.msc and press Enter.
- See if Wi-Fi is present in the "Network adapters" section (May contain the words "Wireless" or "Wi-Fi" in the name. Click on it right click mouse and if there is an item "Enable" in the menu, click it (and if not, then it is already enabled).
Wi-Fi not working on laptop after installing Windows 10, 8 or Windows 7
If the “no connections available” problem occurred to you after installing or reinstalling Windows (or you just never tried to connect to Wi-Fi from this laptop, which is almost the same), then it is almost guaranteed that the problem is in the drivers, moreover, I’m sure if you have already been looking for what to do if Wi-Fi does not work, then you have seen the mention of this reason, but few people mention that the matter may be not only in drivers, not only for Wi-Fi, which will also be discussed.
So, the most important thing you should consider about Wi-Fi drivers:
- Wi-Fi drivers for a laptop should be installed from the official website of the laptop manufacturer (the drivers are located there in the "support" section, as a rule) specifically for your model. If, for example, there are no drivers for Windows 10, you can install for 8 or 7. If they are not installed, try installing in compatibility mode.
- If the device manager for the Wi-Fi adapter says "The device is working properly" and the driver does not need to be updated, this does not mean anything (i.e., in fact, the device may not work normally, but the driver needs to be updated). We still install the official driver.
The most important. And now a subtle nuance concerning wifi work on a laptop after reinstalling the system: if before reinstalling the OS on a laptop (on many models) turn off the wireless network with a key on the keyboard (or Fn + key), then after installation, even with the original wireless adapter drivers, you will see a message that there are no available connections and a red cross on the connection icon - because the adapter is disabled from the point of view of Windows. And sometimes the same thing happens without prior turn off Wi-Fi.
At the same time, just the drivers and utilities for the operation of these keys are what many do not install, and they are not in the driver packs.
It's easy to check if you have it installed - try using any of the function keys from the top row (except for sound and brightness - they can work like that). If they do not work, it is quite possible that the reason for the not working Wi-Fi is this.
The solution is to install all the necessary official utilities for your laptop model so that the function keys in top row earned on the laptop keyboard. And then turn on the adapter with the keys. Moreover, in some cases this is not the only utility, but immediately a set of drivers and utilities from the manufacturer, so the best option is to install all official drivers from the support page of your laptop.
As a rule, such official utilities are named in the spirit: Hotkey Utility (Asus and Acer), Keyboard Driver, Launch Manager (Acer), Hotkey Features Integration (Lenovo) and the like.
which, in turn, may require additional official utilities, such as, for example, HP Unified Extensible Firmware Interface (UEFI) Support Environment and HP Software Framework for HP laptops (plus, some of them may additionally require an HP Wireless Button Driver for turning on Wi-Fi), and for laptops Lenovo drivers these keys are a whole package that includes the System Interface Driver and other software.
So, in order, we install the official drivers until the function keys work (at the same time, the option is that the necessary drivers / utilities are only for previous versions The OS that was originally installed on the laptop is very common, please note and try to install them), and after that we try to turn on Wi-Fi on the laptop.
Equipment, especially computer technology, can sometimes behave extremely capriciously and present various surprises. Just yesterday, you could use your laptop without any problems, surf the Web 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 cryptic message glows: "There are no connections available." And what to do in such a situation is not entirely clear. We will try to analyze in as much detail as possible the causes of such a problem and tell about the most effective ways her decisions.
First, we turn to those who have encountered a similar problem after buying a brand new laptop or just reinstalled Windows. If in one of these situations on your laptop you see a message: “No connections available”, then most likely the problem is with the network driver, which can easily be missing from the system after reinstalling Windows. Another reason in laptops of various models may be a mechanically disabled Wi-Fi adapter. You will learn how to understand which of the two situations became the primary source of the problem in your case from the instructions below.
If a laptop running Windows reported connection problems very unexpectedly, and yesterday everything was in in perfect order, there may be a few more problems, and we will tell you about each of them today.
Any device can experience difficulties in operation and even freeze like Windows sometimes freezes. Since the router distributing wifi signal, is, in fact, the same computer with an operating system and a processor, then it can also stop working or freeze. At the same time, a working indication on its case can mislead the user and create the appearance of normal operation of the device, but no signal comes from it at this moment.
The indication on the device does not always report network problems
To return the router to normal working condition, you need to unplug it, wait a few seconds (7-10) and plug it back in. After giving the device a minute to turn on and start all systems, try again to check for available networks in your laptop.
If you receive a Wi-Fi signal directly from the provider, contact support and describe the situation, mentioning that you do not have available connections. The operator will be able to remotely reboot his equipment.
The problem is the disabled network adapter
Please note that many models of modern laptops running Windows provide for mechanical enabling and disabling of the Wi-Fi connection function. This saves battery power. Find the toggle switch on the ends of your laptop case 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. You can check this information in the manual for specific model.
After such mechanical inclusion wireless network adapter, try searching for available connections again.
The problem is in the software disabled network adapter
Also wifi adapter in your laptop can be deactivated in Windows itself programmatically. To turn it on and try again to find available networks you need to launch Panel Windows controls, go to Network and Sharing Center and public access, and then in the column located in the left part 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 turn it on 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 experiencing 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 clicking the right mouse button 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
For the work of each function of the operating Windows systems responds to any specialized program. And for the operation of each component in your laptop is responsible system program, which is called the driver. It is she who corrects the operation of devices, gives them system commands and monitors the correct execution of these same commands. If your system is missing a driver or has a version installed that does not exactly match this network adapter, you may also experience difficulty finding networks, connecting them, and transferring data.
There are situations in which the driver was installed, configured, and the system worked quite correctly, but after another simple reboot, you saw the message “No connections available”, and you can’t go online. Probably in your operating system there is a program that is responsible for automatic update and installing drivers various devices, and after a reboot, a driver version was installed that does not match the network adapter model, or a test build that does not yet 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, install 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 Dispatcher Windows devices by right-clicking on its name and going to Properties > Driver > Uninstall.
After installing the latest driver and rebooting the PC, search for available networks again to make sure that all systems are working correctly and to connect to the network.
The problem is an incorrect system configuration or registry violation
When all the previous methods have been tried, but none of them have given the desired result, you can resort to really serious and deep troubleshooting and system problems. 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 individual parts of the system. Any of these actions could not have the best effect on the network in your laptop, and then you should resort to the following steps.
If you have a backup copy of your system created using specialized software, try restoring the system to the state it was in at the time the last checkpoint was created. This procedure will cancel all last 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 may deprive you of a large number of settings, programs and options that have appeared on the system recently.
If such backup if you don't, refer to the built-in Windows recovery system, which creates checkpoints during some key procedures performed with the computer. To do this, open “Properties of your computer” by right-clicking on the “My Computer” icon on the desktop, and then look for the item “System Protection” in the column located on the left in the window that opens. Press the "Restore" button and select the system state point that needs to 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 integrity check Windows files. To do this, there is a special service that can be started using the command line.
Open command line, 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 properly, the scanning service will try to detect them and restore them to their original state. This procedure can take quite a long time, and upon its completion, a mandatory reboot of the system will be required.
As a rule, troubleshooting problems with no available connections does not require serious skills and is rarely a reason to contact service center. You can restore the operation of the wireless network adapter using one of the methods given 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.
Home Internet Connection status: "No connections available"
Hello dear subscribers and guests of our blog! Now we will understand why the icon wireless networks Wi-Fi is crossed out with a red cross and writes no connections available when there are definitely available networks. After that, we will try to solve this problem. It all looks like the picture below.
At the same time, the status "No connections available" is displayed. Even if you go to network connections, then the connection for wireless networks will also have a red cross. And next to it will be the status "No connection".
Turning off and on again does not help in this situation. The computer still does not notice available Wi-Fi networks. If you are sure that wireless networks really work (it is better to check with another device), then you need to deal with this situation with a laptop.
What could be the reason?
Similar oddities have been repeatedly observed when turning off wireless networks using keyboard shortcuts along with the function key. If you press Fn + F2 to turn off Wi-Fi (it can be different in different laptops), sometimes nothing can turn off. Although there is a message about disabling wireless networks. But after the next turn on of the computer, we see an already familiar picture with a crossed out icon and the absence of available networks. At the same time, if you try to activate everything through the hot keys (Fn + F2), nothing happens.
You can try to restart your computer, maybe everything will work. But if this does not help, then you can use the "Diagnostics of problems." Oddly enough, but it helps, and the system automatically fixes everything. But first, you should try all the options: hotkeys for activating the wireless adapter, check if the wireless networks really work and then run the diagnostics.
We solve the problem when the connection status: "No connections available"
Right-click on the network connections icon in the notification area. In the context menu that opens, select "Diagnosis of problems." For some time the system will search possible problems. After that, a second window will open, offering to activate the ability to use wireless networks. Just click on the "Apply this fix" button.
Then a report will appear on the correction network problems. From now on, everything should work and the laptop should detect available Wi-Fi networks. Close this window by clicking on the "Close module" button.
Now you can again use the Internet via wireless wifi network. If you have any questions feel free to write them in the comments. See you in the next article!

Internet does not work via cable on a computer and laptop
As part of this article, I want to elaborate on what to do if the Internet does not work via a cable on a computer or laptop. After all, even though in last years users began to massively switch to the use of wireless networks, many still use a wired connection. Firstly, it is more reliable, secondly, the data transfer rate is still higher than that of WiFi, and thirdly, not everyone has a router: someone cannot buy it, but someone is satisfied with connecting the provider's cable " directly", that is, directly to the network card of a PC or laptop. First you need to decide what is happening, because there can be many options for the development of events. I will list the most common cases. By the way, basically, most problems with network access occur after reinstalling Windows. No one bothered to look at and write down the old settings, but on new system no one knows what to set up.
Unidentified network
In Russia, most providers provide Internet access using the PPPoE protocol. That is, in order to access the global web, you need to start a high-speed PPP connection. If the computer is connected to the provider's network directly, without a router, then nothing will initially work through the network connection itself, and therefore it will burn Exclamation point with the comment "Unidentified network" and "no internet access".
There is nothing "criminal" here. You just need to create a high speed connection. An example for Windows 7 can be found here, and for Windows 10, see the video:
There are also a number of providers that provide subscribers with the IPoE connection type according to the Dynamic IP standard. There it is enough just to connect the cable included in the apartment to the network card and you can work. Almost the same picture will be if the computer is connected via a router. But in this case, not always everything goes smoothly. Sometimes it is not possible to connect the Internet via a cable due to incorrect settings of the TCP / IP protocol, namely, because the addresses are registered there statically, and there should be checkboxes for automatically receiving them. To fix this, you need to press the key combination Win + R and enter the command: ncpa.cpl.
Click on the "OK" button. So you get into the network Windows connections 10, where you need to find the network card and right-click on it. In the menu that opens, select "Properties".
No connections available
If you have a red cross on the network icon in the system tray, and in the appearing comment Windows writes “Not connected: no connections available”, then the reasons for this may be the following:
1. Problems with drivers. Firstly, users often simply forget to install them, as a result of which the Internet via cable disappears after the system is reinstalled. Finally the list network connections generally remains empty. Secondly, after the release of Windows 10 on many old and not very laptops, there was a compatibility problem. To date, many manufacturers have already posted new versions of drivers with support for this version of the OS.
2. System failure or playful hands of the user himself. When checking, it turns out that the adapter is disabled in the Device Manager:
On Windows 10, in this case, the network card icon will have a circle with an arrow, and on older versions, a red cross. To enable it again - right-click and select the "Enable" menu item.
3. In my practice, there have been cases when the network disappears due to BIOS glitches or its more modern counterpart - UEFI, as well as in case of incorrect settings. Therefore, if the adapter is integrated, then it makes sense to check this. For this you need to go to Computer BIOS or laptop and go to the section responsible for integrated devices. It is usually called "Integrated Peripherals", or "On-board device configuration".
You need to go into it and find the item responsible for the network card - OnChip LAN Controller, Integrated NIC or OnBoard LAN - and check that it has the Enabled value.
4. It may also happen that your network card on your PC has completely burned out. To check, you need any other device with a LAN port (laptop, modem, etc.). If you are connected through a router, then just try to reconnect to the adjacent connector.
5. Physical damage due to which the Internet does not work via cable. Diode-indicator on network map it does not burn. And if it's a simple patch cord between a computer and a router, that's not so bad. And if this is a provider's cable coming from the entrance, then it's rubbish!
Disconnect the patch cord from the computer, look at the connector - if it is damaged, if one or more wires are broken. Walk along its entire length to the driveway distribution box and carefully inspect for damage to the wire. If it's intact, call technical support and find out if there are any problems with the house switch to which you are connected. During installation, they are often liked to be connected to lighting, which causes the device to periodically lose power.
The network is working but there is no Internet access
Such a scenario usually generally shocks the user. It seems that the network connection is active, it does not give any errors, but there is no Internet. As a rule, the reason lies in the DNS servers: they are either incorrectly specified or not registered at all. For small telecom operators, it also happens that the server itself does not work.
It's easy to check. Press the key combination Win + R to open the Run window and enter the command:
Ping 8.8.8.8 -t
It looks like this:
Here, the IP address 8.8.8.8 is the public Google server, which is always available and the cases when it did not work can be counted on the fingers.
Click on the "OK" button and look at the result. If the response from the IP address is received without loss, then there is Internet access and the reason is clearly in the DNS. We go into the network connections of Windows 10 and open the properties of the IP protocol version 4.
If you need to either set the automatic receipt of the DNS address, or, if this does not work, we write it manually:
Preferred server: 8.8.8.8 Alternate - 77.88.8.8
Click the "OK" button and check access to the global web.
do not forget another possible culprit, due to which Internet access is lost - this is the computer's security system: antivirus, firewall, various security applications. Try deactivating it completely for the duration of the diagnostic. If after that the problem disappears, you need to carefully understand why this is happening.
If the ping does not go through and as a response you receive the message “Query timeout exceeded” or “Unidentified network”, then you need to check the router settings if you are connected through it, or call the provider if the LAN cable included in the apartment is turned on to the PC network card.

No WiFi connections available
An increasing place in our lives is occupied by computer networks even those who have desktop computer, trying to install a Wi-Fi module. But such a solution has negative points in the form of connection problems. The most common of these can be considered a message from your device that there are no WI-Fi connections available, although the router is turned on.
There may be more than enough reasons for this problem - the main ones are:
- Incorrectly configured router or its incorrect operation.
- Lack of drivers for the Wi-Fi module.
- Malfunction of the router or module in the computer / laptop.
- Glitches in the computer system or router firmware.
What to do
The first thing you will need to do, no matter how trite it may sound, is to restart both the dispenser and the computer. The fact is that when loading the system or firmware, a small failure may occur, which will not be displayed on the overall performance, but may well cause a connection problem.
If the situation has not changed after the reboot, then move on.
