What if the Wi-Fi adapter does not connect to the network? Why does not work Wi-Fi on a laptop (netbook)? How to connect a laptop to a Wi-Fi router? The error "Windows failed to connect to ..." does not want to connect to WiFi

If Android does not connect to WiFi, then most often the user sees the message "Get IP Address" or Notification "Authentication Error". Another common connection error - Android writes "Saved, WPA / WPA2 protection", but it does not enter the Internet.

This article is suitable for all brands producing phones on Android 10/9/8/7: Samsung, HTC, Lenovo, LG, Sony, Zte, Huawei, Meizu, Fly, Alcatel, Xiaomi, Nokia and others. We are not responsible for your actions.

Attention! You can ask your question by a specialist at the end of the article.

Possible causes of failure

If Android cannot connect to Wi-Fi - for example, instead of an active Waifa icon you see a gray button and an exclamation mark icon - then the reason for this may be:

1. Wrong from Wi-Fi.
2. Installing an unsupported type of protection or wireless standard in the router settings.
3. Problems with Android firmware.

First of all, it is necessary to understand what device problems arise. If only your phone is connected to the point, the reason should be signed in its settings and firmware. If a wireless network does not find any device, then check the router settings.

Message "Getting IP Address"

If when you try to connect the connection, a message appears with the text "", but the connection is not installed, then the reason for this may be disabling the DHCP server in the router settings or problems in Android. Help can a simple reboot of the router.

If a failure occurred in the DHCP server, the restart of the device will eliminate it. When saving an error:

1. Open the router settings.
2. Make sure the DHCP server is turned on.

Increase

Depending on the router model, the inclusion / disconnecting DHCP may vary, so you need to look for instructions for your device.

Authentication error

If the authentication is connected when the error ends, then, most likely, the cause of the problem is the wrong Wi-Fi password entry. To resolve the error:

1. Forget the wireless point on your phone / tablet.
2. Restart the router.

Increase

1. Change the password using only Latin letters and numbers.
2. Make sure that the WPA2-PSK standard is selected for network authentication.

Increase

If the phone does not support the WPA2-PSK standard, then select another mode - WPA, WPA2. It is clear that in the subway or the mall you can not do it, so it remains only to accept. But at home or at the hotel you can access the router and check the parameters of the wireless network.

Saved, WPAWPA2 protection

If the connection is carried out without a password, then the authentication errors can not be. Nevertheless, the other situation happens - the network is preserved, but. It usually helps the reboot of the router, but sometimes it has to be closed in the settings deep enough.

Increase

In addition, look at the number of allowed devices. If it is "0", it means there are no restrictions.

Network Detection Problems

If, then it also helps the change in the region and the channel. If Russia is selected in the settings, the router is automatically connected to the channels from 1 to 13. However, some devices do not support channels more than 10 - an error appears. To eliminate it:

1. Put the US region - it has only 10 channels.
2. Change the channel to one of the row 1-10.

If it does not help, make sure the network see other devices. Perhaps the cause of the problem should be sought in the work of the Wi-Fi module on Android.

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.

A fairly common problem today is that WiFi does not connect on a laptop. Usually the lack of data transmission over a wireless interface is due to incorrect software configuration. The first item in this list is random disabling the adapter on the keyboard or using a special bedlight on the housing. Next, you need to check the driver (a program that manages the work of the adapter) and, if necessary, reinstall it. At the last stage, check the network settings. Phaood

the execution of all these items in most cases allows you to eliminate such a problem when WiFi does not connect on a laptop.

Turn on adapter

On the keyboard of most modern mobile PCs, there is an extended function keyboard. It can be used by pressing the special key - "Fn". In this case, the standard set of characters stops working, and you can only enjoy additional. It includes a key with an antenna and extending waves. On most models, it is located in the functional set "F1" ... "F12". If you press the "Fn" immediately and without releasing its key with an antenna and extending waves, then there will be inversion of the current state of the adapter. If it is turned on, it will turn off. To return it to the original state, you need to click on the previously presented key combination. It is important to pay attention to the WiFi LED indicator. If it is turned off, then it will have to turn on, then the adapter will be in the on state, and will be possible.

The second possibility of turning off the wireless network card - using a toggle. The principle of operation is similar to the previously reduced, with the same combination on the keyboard. When transferring it from one position to another picture will be similar - WiFi does not connect on a laptop and the corresponding indicator does not light. To turn on the adapter, it must be returned to its original state. Depending on the model

mobile PC, can be used both the first and second way of disconnection. In premium models, their combination is possible.

Check Driver

Next you need to check the correctness of the installation of the network adapter driver. Its failure can lead to the fact that the laptop does not connect to WiFi. First you need to find a disc that comes complete with the device. If it is not, then you download the installer from the site of the official manufacturer on the Internet. Then go to the Start address \\ panel here we reveal the "Network Adapters" item and look at the wireless card. If there are no icons in front of it - it means that it is proceeding for the next stage. We highlight our wireless adapter with the left mouse click and click "Del". This deletes existing drivers. Then we launch the installation of new from the disk or downloaded file. After that, it is recommended to restart the system. If it did not solve the problem, go to the next stage.

Check network settings

At the final stage, check the connection settings. To do this, open

double-click the left button "Current connections" (label with increasing chopsticks On the right side in the list that opens, select the properties of the required Next, you need to check the type of encryption (it should be the same as on the router) and password for access. If the password accidentally changed, It is necessary to check the PC for the presence of viruses. After all three stages are such a problem, when WiFi does not connect on a laptop, in most cases it is solved.

Conclusion

If all the operations set forth in the article are fulfilled, and the result is not achieved, that is, it makes sense to seek help from a qualified specialist. As practice shows, in most cases the proposed manipulations allow you to solve such a problem at which the laptop has stopped connecting to WiFi, and the transfer of a wireless network is restored.

Laptops have an advantage over personal computers in the face of the built-in Wi-Fi adapter, with which users can connect to Wi-Fi wireless networks. However, PC owners easily can acquire an external Wi-Fi adapter and just enjoy the benefits of wireless technologies.

Nevertheless, some PC users notify that, sometimes, their external Wi-Fi adapters for some reason cannot connect to the network, distributed by their router. The root of the problem can be in a lot of: failed driver, problems with the router, operating system settings, etc..

In this article we will tell you what can be done if your Wi-Fi adapter can connect to the distributed network.

Check the Wi-Fi Wi-Fi

Let's first think about what: And did you think about what, perhaps, the problem with connecting to the network is not a Wi-Fi adapter, but in the router that simply does not distribute the wireless network? Check it is quite simple: take another device that is capable of connecting to the Wi-Fi network, and try to connect with it to your router.

In the absence of other devices, you need to go to the settings of your router and make sure it is activated for distributing the wireless network. There are cases when settings in such devices for some reason are knocked down by themselves. All you need to do is enter the interface and activate the option Wi-Fi distribution.

Disable the "aircraft" mode

As we all know, in Windows 10 there is a pretty convenient "aircraft" mode, with which you can disable all wireless modules that are in your system. Of course, after activating this mode, your external Wi-Fi adapter is deactivated.

The mode "on the plane" is extremely useful on mobile devices and laptops, but it is absolutely not needed on stationary computers. Nevertheless, you could accidentally turn it on, for example, digging in settings or using a special combination. There is also an opinion that the "airplane" mode may include third-party software.

Deactivate the "plane" mode is incredibly simple: click on the notification center icon and click on the button of the same mode. That's all that is required of you. If you did not find this option in the notification center, you can contact the system parameters and turn it off there.

Restart Wi-Fi router

Realizing that the distribution of the wireless network is activated and your Wi-Fi adapter is not blocked by the system settings of the computer - try to restart your router. There is a chance that it began to work with failures, as a result of which you cannot connect to the network using third-party Wi-Fi adapter devices. Restart is extremely simple: Disconnect the power router for about ten-fifteen seconds, and then turn it on again to the network. It is worth saying that routers can often climb, which leads to a number of unpleasant problems: reducing the speed of the network connection, blocking certain connections or all access to the Internet.

Application Tools troubleshooting

A fairly simple way to solve a network connection problem is to use a network troubleshooting tool. You do not have to go anywhere for him, download or spend search on the network, since this tool is a system utility, access to which is incredibly easy. To do this, you will need to do the following:

• go to the parameters;
• go to "Update and Security";
• go to the Troubleshooting tab;
• click on "Internet connection";
• click on the "Run troubleshooting tool" button;
• follow the instructions on the screen.

It should be said that this system tool, unfortunately, almost never solves any problems that have arisen in any element of the system. However, sometimes the stars sometimes agree on the sky - and a miracle happens. Try to use this troubleshooting agent, then check whether you will connect the Wi-Fi adapter to the wireless network.

Updating Wi-Fi Drivers Adapter

You may not normally use your Wi-Fi adapter simply due to the fact that its drivers are outdated. By updating the driver, you can get rid of the problems encountered. You can run the drivers through the Device Manager:

• click Windows + X;
• select Device Manager;
• find and open the "Network Adapters" section;
• right-click on the Wi-Fi adapter and select "Update Driver ...";
• select an automatic driver search on the Internet;

By updating the driver for a Wi-Fi adapter, try to connect to your router wireless network. In most cases, users who have a similar problem, allow it to update the driver for the device.

Roll back to the previous version of the driver

Nevertheless, even a new version of the driver can cause problems when using a Wi-Fi adapter, however, it all depends on the manufacturer of the device. Perhaps the latest version of the Wi-Fi adapter driver is extremely unstable or it is incompatible with your computer. In this case, you can try to roll back the installed driver before the previous version.

Make it can also be accurately using the device manager:

• get to your Wi-Fi adapter in the list of network devices;
• double click on the left mouse button on the Wi-Fi adapter;
• go to the "Driver" tab;
• click on the "Rollback" button;

Running to the previous version of the driver for the Wi-Fi adapter, try using it and connect to the Wi-Fi router network. If it really was in the driver, then you will immediately understand this.

Temporarily turn off the firewall

If nothing of the above helped you solve the problem, then it is possible to connect to a wireless network prevents your Windows Firewall, which for some reason blocks the network connection. One way or another, you can check it elementary: you just just take and turn off the firewall system for a while.

This can be done as follows:

• click Windows + S;
• enter and select the Windows Defender Security Center request;
• go to the "Firewall and Network Security" tab;
• deactivate the firewall for the domain network, frequent network and public network;

Try to use the Wi-Fi adapter and connect to the wireless network driven by your router. We hope that you finally did everything, and your adapter still earned.

Found a typo? Highlight the text and press Ctrl + Enter

Before you begin to find out why Wi-Fi or Internet does not work, you should know (especially for those who only purchased a Wi-Fi router), which is just enough to connect the provider cable to the router, it still needs to be configured (configure Internet and Wi-Fi network ). All the following methods are valid if you have worked Wi-Fi and the Internet before you, and then suddenly stopped or you cannot connect a new device to Wi-Fi. For convenience, I divided the article into two parts, the first is dedicated to the impossibility to connect to the wireless network, the second part will respond to your questions if you connected to the Wi-Fi network, and there is no Internet.

Cannot connect to Wi-Fi network.

Reloading the router.

The first thing you need to do when problems with connecting to a Wi-Fi network is to restart the router. To do this, simply disconnect the power supply from the router and later connect again. After 1-2 minutes. The device will boot, then try connecting again to the wireless network. To further avoid such situations, I recommend to update the router firmware (perhaps the manufacturer knows about the problem and corrected it in the new firmware).

Enabling Wi-Fi module on a laptop.

Check whether Wi-Fi is enabled on a laptop, I will not turn on, I described all Wi-Fi in the article How to enable wi-fi on a laptop .

Changing the wireless network mode.

If you are trying to connect the device (laptop, smartphone) to which more than 5-7 years, it is necessary to consider that it may not support the modern Wi-Fi mode - n.. Therefore, you need to switch the router to operation mode, which is supported by the device or enable mixed mode b / g / n. More information about Wi-Fi modes is described. In order to switch the wireless network mode, you need to go to the web interface of the router, go to Wi-Fi settings and select the appropriate mode.

Deleting the SSID refined network name.

One of the possible problems is not able to connect to Wi-Fi - it is a duplication of the Wi-Fi network (SSID). Suppose you came to your acquaintances, they have a Wi-Fi network called "home", you have successfully connected to it. Time passed and already from other acquaintances or at home you met the same network name. Laptop (this also applies to tablets, smartphones) Attempts to connect to the network using a saved earlier password, but it cannot succeed because a new password is used for this name. To solve this problem, it is necessary to remove the coinciding network from the list of saved Wi-Fi networks.

To do this, right-click on network icon In the lower right corner of the screen and select "Network and Shared Access Center".

After that you will see a list of saved wireless networks. If you see that the network to which you are trying to connect is in this list, you must delete it from this list. Select the network and click the Delete button. After that, to connect a wireless network, you will need to enter a password.

No Internet via Wi-Fi.

Checking the payment of the Internet.

The simplest thing that may be with a non-working Internet - it's time to pay for it or work from the provider. To find out the situation, call the provider and check if you have a debt for the Internet and are not working on the line.

Static IP address.

One of the problems not to work the Internet may be a prescribed static address not with the network settings that are necessary. In this case, I recommend using automatic receiving network settings. To do this, you need to get into the Network Management Center and Common Access. One way to do this is the right mouse button on network icon In the lower right corner of the screen and select "Network Management Center and Common Access".

Another method is to use hot keys + , Enter the command NCPA.cpl And press ENTER.

It does not matter how much way you used the result will be one - the network connections window will appear on the monitor. Next, you need to click on the wireless connection with two mouse clicks, in the state window that opens, select "Properties" in the Properties window "Internet version 4 (TCP / IPv4)"

Problem with router.

The Internet may not work because of the router failure, the simplest thing that can be done is to restart it. Situations occur when the router resets the Internet settings, then it is necessary to connect to it on a web interface and re-enter the Internet settings, to further experience less problems with the router, I recommend updating its firmware.

Conclusion

In this article I described all methods for solving problems with Wi-Fi and Internet. If the specified methods did not help you, you can describe in detail the problem in the comments and, along with the readers of this site, will try to help you.
