If the laptop after reinstalling Windows or simply without any visible reasons does not work Wi-Fi, it writes that there are no available connections and shows a red cross on the connections icon, the material below describes several possible reasons for this problem and what to fix it.

No available Wi-Fi connections when you turn on the laptop

If you have previously connected to Wi-Fi wireless networks on the same laptop, and now, without any actions with drivers, without reinstalling Windows, you suddenly write you that there are no available connections, this usually means that for some reason Wi- Fi adapter turned out to be turned off.

This is what you should pay attention to trying to correct the problem:

In general, these are usually all possible options that help correct the problem, if it does not consist in missing drivers, a newly reinstalled system or some hardware issues. If these options did not help, you can try the following solutions.

Just in case, also check whether the Wi-Fi adapter in the device manager is accidentally disabled by somehow accidentally disabled:

1. Press the Win + R keys on the keyboard, enter Devmgmt.msc and press ENTER.
2. Look, whether Wi-Fi is present in the "Network Adapters" section (may contain the words "Wireless" or "Wi-Fi" in the title. Click on it right-click and if there is an "Enable" item, press it (and if No - it is already included).

Wi-Fi does not work on a laptop after installing Windows 10, 8 or Windows 7

If the problem "No available connections" appeared after installing or reinstalling Windows (or you just never tried to connect from this laptop to Wi-Fi, which is almost the same), then the problem is almost guaranteed to the drivers, and, I am sure if you have already searched what to do if Wi-Fi does not work, then you have seen the mention of this reason, however, there are little to mention that it may be not only in the drivers not only for Wi-Fi, which will also be said.

So, most importantly, you must take into account the Wi-Fi drivers:

1. The Wi-Fi driver on a laptop should be installed from the official website of the laptop manufacturer (drivers there are in the "Support" section, as a rule) it is for your model. If, for example, there are no drivers for Windows 10, you can install for 8 or 7. If you are not installed - try installation in compatibility mode.
2. If the device manager for Wi-Fi adapter is reported that "the device works fine", and the driver does not need an update - this does not say anything (i.e., in fact, the device can work abnormally, and the driver needs to be updated). All the same set the official driver.

The most important. And now the thin nuance concerning the work of Wi-Fi on the laptop after reinstalling the system: if before reinstalling the OS on the laptop (on many models so), turn off the wireless network with the keyboard key (or Fn + key), then after installation, even with original wireless drivers Adapter, you will see a message that there is no available connections and a red cross on the connection icon - because the adapter from the Windows point of view is disabled. And sometimes the same thing happens and without prior shutdown Wi-Fi.

At the same time, just drivers and utilities for the operation of these keys are what many are not installed, and they are missing in the driver-packs.

Check if you are easily installed - try using any function keys from the top row (except sound and brightness - they can work so). If they do not work, it is possible that the reason that does not work Wi-Fi in this.

Solution - Set all the necessary official utilities for your laptop model so that the function keys in the top row on the laptop keyboard earn. And then enable the adapter keys. At the same time, in some cases, this is not the only utility, but immediately a set of drivers and utilities from the manufacturer, because the optimal option is to set all the official drivers from the support page of your laptop.

As a rule, such official utilities are called in Spirit: Hotkey Utility (Asus and Acer), Keyboard Driver, Launch Manager (Acer), HotKey Features Integration (Lenovo) and the like.

Which, in turn, can require additional official utilities, such as, for example, HP Unified Extensible Firmware Interface (UEFI) Support Environment and HP Software Framework for HP laptops (plus on some of them may additionally need HP Wireless Button Driver for inclusion Wi-Fi), and for Lenovo laptops, these keys drivers are a whole package that includes System Interface Driver and other software.

So, in order, we install official drivers until the function keys earn (at the same time, the option that the necessary drivers / utilities are only for previous versions of the OS, initially installed on the laptop - very often occurring, taking into account and try to install them), And then try to enable Wi-Fi on a laptop.

Data transfer without the use of cables literally not yet so long ago, it seemed something from the fiction area, and today the WiFi WiFi WiFi network is not surprising at work or in the near cafe. But with such a connection, some problems may be observed. Connection error - a phenomenon that occurs quite often. Consider the most characteristic problems and the simplest methods of their elimination.

Wireless Network Connection: No Connection. What is the reason?

As for the most common causes, they can be divided into two main types: problems at the hardware level (non-working equipment) and software errors.

In the first case, as it is already clear, you need to carry out complete diagnostics of the equipment, after which it is necessary to make a decision on its repair or replacement (this also applies to network cards, and routers, mobile devices, and external or internal Wi-Fi modules). In the second case, you can call several situations where there is no wireless network connection (no connection). Among the mains are the following:

• disabled module or;
• incorrectly entered password;
• router problems;
• incorrect connection settings;
• missing, incorrectly installed or outdated network devices drivers;
• lack of installed network;
• impact of viruses.

Problems with viruses will not be considered for obvious reasons, since any user must take care of the protection of its system on their own. Partially affect the absence of the network, if for some reason it was installed in the system, but then it disappeared (this, unfortunately, is also there). Finally, we will not stop on the fact that the user could forget or incorrectly enter a wifi-network password, and problems from providers. These situations in our case are not so significant.

Wireless Network Connection: No Connection. What to do in the most simple case?

To begin with, consider the simplest situation. Suppose, a wireless network connection is lost at a certain point. Perhaps the reason is a short-term programmatic program. What is usually in such cases makes most users? They just reboot the system (after all, before that everything worked).

If this does not help, and the time to lose the signal is known at least approximately one of the options to solve the problem that when you try to connect to an existing network, the connection error pops up may become a regular system rollback to the previous state through the corresponding section "Control Panel". But, as practice shows, the problem is usually much deeper.

Diagnostics Connection by means of the system

If for some reason the Wi-Fi wireless network connection disappears, it is possible to find out the reason using Windows. If you call the menu through the right click on the network icon in the system tray, you can use the troubleshooting tool.

The system will independently analyze, after which it will give the relevant result. Please note: this tool does not fix anything, but only helps to determine the essence of the problem.

Wi-Fi Module Activity Check

One of the most common causes of the lack of communication, many experts call inattention or negligence of users.

For the most part, this refers to the owners of laptops, on which there is no special switch to activate the built-in Wi-Fi module, and its inclusion or shutdown is made by using a combination of some key with a special FN button. It is clear that even when the text set using the so-called hot keys, it was possible to easily turn off the adapter. Therefore, first you need to make sure that it is in active mode.

Reset router settings

Sometimes the reason that there is no wireless network connection (no connection), it may become a short-term failure of the router. Most often, this situation is observed with low-cost routers of the TP-LINK series.

And in the case it is recommended to use the simplest reset technique, you can do a two way: either completely disconnect the power to about 10 seconds, or press a special reset button on the back of the device and hold it for 30 seconds.

Network settings identification

Now, if not defined, look at the main network settings. To view them, enter the network management and shared access control panel or from the Click menu on the network connection icon and use the parameter change section.

Here you need to find TCP / IPv4 protocol (if IPv6 is not used) and press the properties button. As a rule, most providers represent automatic parameter definition services, which must be fixed in the settings. It is worth paying attention to the fact that the use of a proxy server for local addresses should be deactivated (if otherwise provided). Otherwise, you just need to enter all the parameter values \u200b\u200baccording to the settings provided by the provider when connected.

Correction of connection parameters on the router

If, after that, the connection problem remains, perhaps it consists in the settings of the router itself.

Just in case, you should enter the router parameters menu through any web browser by entering the corresponding address (192.168.0.1 or 1.1), after which in the Wireless Connection section (usually Wireless) make sure that it is active (enabled).

Troubleshooting Drivers

Another network problem may be that there are no network card drivers installed or outdated or outdated. Make sure that the device does not work, you can in the Device Manager, which is called at least from the "Control Panel", at least from the Computer Administration section, at least from the "Run" menu by the devmgmt.msc command.

The non-working device will be marked with a yellow marker. This is a direct indication that something is wrong with the driver. But it happens that among problematic devices is not displayed. This is only due to the fact that the system sets the most appropriate driver for it, considering it optimal.

In any case, it will have to reinstall or update. Make it can be directly from several menus. It is recommended that you first completely remove the old driver, but only then install the new, but do not choose from what will offer the system, and in advance to find the most fresher for this device on the Internet.

So as not to engage in such things, it is better to establish a program like a Driver Booster, which will find and install the newest drivers absolutely for all devices. It is clear that for this, with a laptop you have to go to the same cafe, where there is a connection, and there is no WiFi password for entering the network (there is no connection at home). The update process will take a maximum of 10-15 minutes, followed by a reboot.

Reset the settings from the command line

If the network is still determined, you can try to still make the following actions. We call the command line with the admin rights (CMD in the "Run" console), after which we prescribe the proxyCFG -D command, and after pressing the input key, two more - Net Stop Wuauserv and Net Start Wuauserv (after each - also "input"). Such simple actions can also help.

If the network is not determined at all ...

Finally, the last problem when it is absent is quite possible that due to some reasons, among which the influence of viruses is not excluded, the previously created network was simply removed.

In this case, you need to go to the Network Management section with shared access and make sure that the wireless network is displayed in the list of available connections. If there is no one, it will have to be reinstalled by selecting the appropriate item. Time will be required at least.

If the network is, but all of the above solutions of the problem do not help, you can try to simply delete it entirely and completely, after which it is to create a new and make the appropriate TCP / IP protocol settings.

Conclusion

Finally, it remains to add that these are only the main, most common problems and methods for solving them that any user can use to eliminate failures. Here, there were no different kind of teams specially considered, allowing you to fully test IP connections or assigned MAC addresses, pinging, etc., since they may seem sufficiently difficult for understanding by ordinary users. In other cases, even the simplest means will help. However, this in no way concerns the cases when the equipment fails. There are no software methods here, no matter how trying.

Wi-Fi technology is very widely used in the life of a modern person, because it makes it easy and quickly solving the problem with connecting to the Internet without using conventional wires. This is especially true in the case of using laptops, access the Internet with which you can in any convenient place due to the presence of a built-in Wi-Fi adapter.

That is why the situation when Wi Fi does not work on a laptop, leads to significant inconveniences and even some problems. The reasons for which Wi-Fi may not work on a laptop computer, there are quite a lot. The most serious of them to solve themselves without the help of specialists simply unrealistic, but there are quite a lot of things and such that can be eliminated on their own. Consider them.

Problem in a laptop or router?

A sufficiently common problem is that the laptop stopped connecting to the WiFi network, is the problem not with the laptop itself, but with the router settings, which distributes the network. Thus, the laptop can be configured correctly, but Wi-Fi still does not turn on exactly because he has nothing to connect.

To eliminate the likelihood that the problem is related to this, you should try to connect to the network from any other device that is equipped with a Wi-Fi adapter from another laptop, smartphone, tablet, and the like.

If Wi Fi does not work from another gadget, then the problem lies in the Wi-Fi router distributing the Internet. If the connection is successful - the problem is in the laptop and before it will first need to determine - why Wi-Fi stopped working.

Hardware enable adapter

Based on such a diagnosis, it is possible to accurately determine that this problem arose exactly about the fault of the laptop. When wifi does not work on it, you can try to use in several ways.

The first one is to check whether the wireless connection adapter on the laptop is enabled. Almost all modern models have light indicators of the WiFi module and for its hardware power on there are special key combinations.

Usually, the glowing indicator indicates the on-line module. If the indicator does not shine at all or shines in red, it means that Wi-Fi does not work precisely because of the wireless adapter. It must be enabled.

Most often, such indicators are located directly on the keyboard, side or front panel of the device. Sometimes their location is found on the monitor building or near the touchpad.

To enable the module of such a network, click the Fn key combination and one of the system F1-F12. A specific combination depends on the manufacturer of the laptop. Usually the appropriate antenna icon is located on the desired key. If it is not, then to turn on the WiFay, you should try to click the standard for a specific model:
Fn + F3 for Acer;
Fn + F2 for ASUS, Dell or Gigabyte;
Fn + F5 on Fujitsu devices;
Fn + F12 on HP laptops.

After pressing the appropriate keys, check whether the operation indicator of the wireless connection module lit up or stopped burning red. After that, you should try to connect to the network again. If it did not help - go to the next step.

Software inclusion

When the WiFay stopped and the hardware switching on does not give positive results, it is also necessary to implement its software inclusion, which is carried out directly from the operating system, which is running a laptop.

To implement the WiFi software inclusion that stopped working, on Windows 7, 8 or 10, you need to perform such a sequence of actions:

1. On the notifications panel, which is located near the clock, the network connections status icon are selected;

2. From the opened list, the "Network and Shared Access" or "Network parameters" reference point is selected depending on the version of the operating system;

3. The next step is "Changing the Adapter Settings".

Among the list of all existing connections, you need to pay attention to the color of the "Wireless Network Connection" icon. If your WiFi does not work and the wireless adapter is disabled, the connection icon will not be highlighted. In this case, on its icon, click the right mouse button, from the opened context menu, select the "Enable" item. In this case, the color of the connection icons must change.

In this case, the wireless network adapter is turned on, it remains to be found in the list of available wireless networks you need and connect to it.

If, after such actions, Wi-Fi, which stopped working, continues to inactivate, you need to move to the following method of solving the problem.

Installation and Driver Update

Quite often, the Wi-Fi wireless connection is not included due to the lack of driver or in the case when it is strongly outdated. To determine the presence of the installed driver, you must from the context menu of the "My Computer" icon, which is located on the desktop or in the Start menu, select the item "Properties". Next, in the window that opens, the Device Manager command is selected from the left menu.

In the new window that opens with the list of connected devices, you must find the name of the network wireless laptop adapter. Usually its name is the "wireless network adapter" or "Wireless Network Adapter", together with which the device manufacturer should be specified: Realtek, Atheros, Qualcomm or something else.

Finding the desired item and clicking on it with the right mouse button, the "properties" are selected from the context menu. In the window, which will open at the same time, the "Device works is normal" must be present. But even if there is a mark on the normal operation of the device, this is not a guarantee that the correct driver version and Wi-Fi is installed correctly. To check it in the Wireless Properties window, go to the Driver tab and pay attention to the "Development Date" and "Supplier".

In the event that the provider is Microsoft or the program development date lags behind the current for several years - go to the official website of the laptop manufacturer and download the latest official version of the driver.

The same should be done in the event that there was no wireless adapter among the list of installed devices.

If in the list of devices, the wireless module is present, but marked with a yellow exclamation mark, it means that the device is disabled, resulting in the network and stopped working. In such a case, opening the device properties window, you need to click the "Enable" button.

Another reason why WiFay stopped working on a laptop, can be involved in economical energy consumption, which prevents the operation of the wireless connection. To turn it off, you need to do the following:
1. Open the control panel;
2. Select the "Power" icon;

3. In the window that opens, select High Performance or "Balanced" mode.

External Obstacles for Signal

It is also worth noting that the non-working wireless network may also be the result of not only problems with the laptop. The wireless connection signal depends on some external factors that can relax it. Ceiling, walls, gender and the like obstacles significantly worsen the quality of the access point and laptop signal.

As you know, the quality of the signal on a personal computer is displayed as several marks - the more they are, the more qualitative is the signal. If the wireless connection is displayed as 1 or 2 marks, then you can not attempt to use WiFi - in this case it will not work normally.

In this case, you need to transfer the router closer to your workplace, transfer the workplace closer to Wi-Fi Router or buy a new, more powerful router.

Other reasons for problems with Wi-Fi work

The problems described above the problems with the functioning of the wireless network adapter are most common and can be eliminated on their own.

It is worth noting that all this is software ways to solve problems that are solved by installing, reinstalling or updating the device driver, as well as the implementation of some operations with the OS.

But often the problem with the operation of the wireless connection module lies and in hardware errors. What is this mistakes? These are the problems that are associated directly from the board itself, most often its physical damage.

To eliminate such problems, you will need to disassemble the laptop. It is worth noting that it is possible to perform such actions only in the case of certain skills in this area. If there are no such skills - it is better to entrust the work of professionals.

One of the most common physical damage is the unconnected antenna wire to the contactless communication module. Such a problem occurs with laptops, which were repairing or if their owner independently cleaned the cooling system from dust. In such cases, the antenna sometimes just forget, as a result of which the adapter will not be able to establish a connection even near the source of the signal. To eliminate such a problem you just need to connect to the Wi-Fi module its antenna.

Sometimes the reason that Wi-Fi ceases to work is the usual overheating of the network card. Most often it is the result of the fact that the laptop stands on a soft surface. The whole thing is that at the bottom of the device there are holes, through which cold air, cooling all computer boards, falls inside. Broken these holes, the system overheats, which can lead to failure of certain components.

Another often encountered cause of overheating of the device is dust, which can prevent cold air intake into the cooling system.

That is why in order not to face similar problems, it is recommended to clean up the laptop dust at least once for one year: in this case, it will be possible to repair a portable PC as a result of overheating of its nodes.

In the most running cases, the wireless adapter may even burn. In this case, only his replacement for a new one will help. You can define such a problem using the device manager in which the module simply stops displayed. When you try to install the driver for a wireless network, a message appears that the corresponding device is not installed in the system.

If nothing helped

If none of the tips in the above helps, it is possible to use simple, but at the same time an effective solution: restart and computer, and a wireless router. Note, after rebooting the router turns on up to 5-10 minutes before distributing the network. Be patient. Also, despite the opinions of many skeptics, sometimes solve the problems with the wireless network helps the problem of troubleshooting, which is in the Windows operating system.

Thus, most of the existing problems of problems related to the fact that Wi-Fi stopped working on a laptop. Almost all such methods and recommendations can take advantage of anyone who encountered a similar problem, as no special skills need for this.
If nothing helps, and the wireless network did not start working, there is only one way out - to go for help in a high-quality service center, where any problems with the laptop can be solved.

If the article did not help solve your problem and Wi-Fi still does not work Write in the comments, I will try to help.

Do you have a problem with the Wi-Fi icon in Windows 10? Are you sure that the network card works correctly on your computer, but the Wi-Fi icon is not displayed in the system tray, and you cannot choose which wireless network to connect? See how to solve it.

How to restore Wi-Fi network icon for windows 10

The wireless network icon may disappear from the taskbar in Windows 10, which is quite problematic. Even if we automatically connect Wi-Fi network, and this icon seems unnecessary, ultimately the lack of a network icon may irritate. Especially when we want to connect to the new network or get an overview of the connection status. There are various reasons why the invisible icon. Let's see what we can do to fix it.

Option NO 1 - Check if Wi-Fi icon was hidden

Very simple question, but often it happens that we do not notice it. Icons from the Windows 10 notification area can be moved, and it also refers to sound icons and network icons. We could accidentally drag the icon, and now he is hidden.

Click the Arrow icon to deploy a list of all icons in the notification area. If the Wi-Fi icon appears in the new window among other icons in the tray, simply take it and hold the left mouse button, then drag it to your last place next to the clock.

NO 2 option - Check if the icon was completely disabled

The icon can also be completely disabled on the taskbar. To check this, enter the settings ("Start"\u003e "Settings" menu), and then go to the "System\u003e Notifications and Actions" tab.

On the right side you will find fast action icons from the notifications panel. Below you will find a link called "Enable and disable system icons" - click on it. A new window will appear in which we can manage the display of individual icons from the notification area.

Find the item in the list with the name "Network" and make sure that the switch is set to "On". Return to the screen of the previous settings and this time, click the "Select icons displayed on the taskbar". Find the "Network" in the list and make sure it is also enabled.

NO3 option - Make sure the Wi-Fi network card is enabled

The Wi-Fi icon also disappears when our wireless network card is disabled. In this case, the icon is replaced by the local (cable) network icon, which looks completely different. If the Wi-Fi map is disabled, the classic Wi-Fi icon with three bars will not be visible.

Go to the "Start" menu, then find the "Control Panel" and run it. Then go to the "Network and the Internet\u003e Center of Network Management and Sharing" and select "Change Network Card Settings" in the side menu on the left. A list of all network cards (LAN and WLAN) on a computer / laptop will appear. Make sure the Wi-Fi card is turned on. If the gray icon, right-click the tab and select "Enable".

If you have a laptop, also check that the Wi-Fi switch on the laptop lid was not moved to the "off" position. If this happens, switch it to run the Wi-Fi network card.

NO 4 option - Check if the icon was blocked by a local group policy editor (only Windows 10 Pro and Enterprise)

The last way is to check if the icon was completely blocked. To do this, we will use the Local Group Policy Editor. This option works in Windows with the release of Professional and Enterprise.

Press the Windows + R keys combination, and then enter the gpedit.msc command in a new window and confirm its Enter key. The Local Group Policy Editor window opens. Expand folders on the left to the next way:

User Configuration\u003e Administrative Templates\u003e Start menu and Taskbar

Select "Menu" Start "and" Taskbar ", and then find the item on the right side of the search." Delete network icon ".

Double-click it to view this policy details. In a new window, select the "Disable" check box to ensure that the "Delete Network Icon" option is disabled. Confirm the changes to the OK button.

After the release of the new version of Microsoft software, problems are growing like a snowball. And one of them is the lack of the Wi-Fi or settings button, which leads to an error: "Failed to find wireless devices on this computer." So, the topic of the article is to solve the issue with the button, with the settings and turning on the wireless network in Windows 10. If the computer does not turn on the wireless internet (there is no button, no settings, etc.), the problem lies, or in the adapter, or in the driver Wi-Fi.

If the problem with the driver or adapter decided and the Internet is stable, you can turn your laptop, a stationary computer into the router. Create hot-spot (how to implement it, we have already written before) and distribute the Internet to the peripheral devices - PCs, smartphones, tablets, ultrabooks.

Interesting advice received in the comments:

• Open the system disk, for example, "C" and use the search folder "Wireless LAN".
• Go to: C: \\ ESUPPORT \\ EDRIVER \\ Software \\ Wirelesslan \\ Qualcomm Atheros \\ Wirelesslan \\ 10.0.0.342 \\ 2886 \\.
• There are two installation, setup, file. Open both files, and the problem will be solved.
