The laptop sees the wifi but does not connect. My phone won't connect to Wi-Fi: what should I do in this situation? Enabling WiFi on a laptop

Wi-Fi technology is very widely used in life modern man, because it allows you to easily and quickly solve the problem with connecting to the Internet without using ordinary wires. This is especially true in the case of using laptops, with which you can access the Internet in any convenient place thanks to the 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 why laptop Wi-Fi may not work, there are quite a few. It is simply unrealistic to solve the most serious of them on your own without the help of specialists, but there are quite a few that can be easily eliminated on your own. Let's consider them.

Is there a problem with your laptop or router?

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

To exclude the possibility 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 that distributes the Internet. If the connection is successful, the problem is in the laptop and before solving it, you first need to determine why Wi-Fi stopped working.

Hardware enable adapter

Based on such a diagnosis, it can be accurately determined that this problem arose precisely through the fault of the laptop. When Wi-Fi does not work on it, you can try using several methods.

The first one is to check if the wireless adapter on the laptop is enabled. Almost all modern models have LED indicators of the WiFi module's operation and there are special key combinations for its hardware activation.

A normally lit indicator indicates that the module is turned on. If the indicator does not glow at all or shines red, then the wi-fi is not working precisely because of the wireless network adapter. It needs to be turned on.

Most often, such indicators are located directly on the keyboard, side or front panel of the device case. Sometimes they are located on the monitor case or near the touchpad.

To enable the module of such a network, press the Fn key combination and one of the system F1-F12 keys. The exact combination depends on the laptop manufacturer. Usually, the corresponding antenna icon is located on the desired key. If it is not there, then to turn on the wifi, you should try to press the standard for specific model combination:
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, we check whether the indicator of the wireless module's operation is lit up or whether it has stopped glowing red. After that, you should try again to connect to the network. If that doesn't help, go to the next step.

Software inclusion

When the wifi has stopped working and its hardware activation does not give positive results, it is also necessary to turn it on in software, which is carried out directly from the operating system under which the laptop is running.

To programmatically enable WiFi that has stopped working on Windows 7, 8 or 10, you need to perform the following sequence of steps:

1. On the notification panel, which is located near the clock, the icon for the status of network connections is selected;

2. From the list that opens, select the item "Network Control Center and general access"Or" Network parameters "depending on the version of the operating system;

3. The next step is "Changing adapter parameters".

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

In this case, the wireless network adapter turns on, it remains to find the desired one in the list of available wireless networks and connect to it.

If, after such actions, Wi-Fi, which stopped working, continues to be inactive, you need to move on to the next method for solving the problem.

Installing and Updating the Driver

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

In the new window that opens with a list of connected devices, you need to find the name of the laptop's wireless network adapter. Usually its name is "Wireless Network Adapter" or "Wireless Network Adapter", along with which the manufacturer of the device must be listed: Realtek, Atheros, Qualcomm or something else.

After finding the desired item and clicking on it with the right mouse button, select "Properties" from the context menu. In the window that will open at the same time, the item "Devices is working normally" should be present. But even if there is a mark about the normal operation of the device, this is far from a guarantee that the correct version of the driver is installed and Wi-Fi is turned on correctly. To check it, in the properties window wireless device go to the "Driver" tab and pay attention to the items "Development date" and "Supplier".

In the event that the supplier is Microsoft or the development date of the program is several years behind the current one, go to the official website of the laptop manufacturer and download the latest official version of the driver.

The same should be done if among the list installed devices there was no wireless adapter.

If in the list of devices the module wireless communication present, but marked with a yellow exclamation mark, this means that the device is disabled, as a result of which the network has stopped working. In this case, after opening the device properties window, you need to click the "Activate" button.

Another reason why Wi-Fi stopped working on a laptop may be that the power saving mode is activated, which prevents the wireless connection from working. To disable it, you need to do the following:
1. Open the Control Panel;
2. Select the "Power supply" icon;

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

External signal barriers

It's also worth noting that a broken wireless network can also be the result of more than just laptop problems. The signal of a wireless connection is affected by some external factors, which can weaken it. Ceiling, walls, floor, and similar obstructions significantly degrade the signal quality of the access point and laptop.

As you know, the signal quality on personal computer is displayed in the form of several marks - the more there are, the better the signal is. If the wireless connection level is displayed as 1 or 2 marks, then you do not need to try to use WiFi - in this case, it will not work normally.

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

If all else fails

If none of the tips above helped, you can use a simple yet often effective solution: restart both your computer and your wireless router. Please note that after a reboot, the router turns on for up to 5-10 minutes before it starts distributing the network. Be patient. Also, despite the opinion of many skeptics, sometimes the troubleshooting function, which is in the operating room, helps to solve problems with the wireless network. Windows system.

Thus, most of the above was listed existing solutions problems related to the fact that the laptop has stopped working Wi-Fi. Almost all of these methods and recommendations can be used by anyone who has encountered a similar problem, since this does not require any special skills.
If all else fails, and the wireless network does not start working, there is only one way out - to go for help in a high-quality service center where any laptop problems can be solved.

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

Wireless networks are very widespread these days. This is because no cable connection is required to connect to the access point. This, in turn, allows users to freely navigate to the coverage area. But what if the laptop won't connect to WiFi? This is what will be discussed in this article.

The fact is that the question of why I can't connect to a WiFi network from a laptop is often encountered due to a variety of hardware problems, and not every user is able to solve them on their own. There can be many reasons for a failed connection. We will analyze the most common errors and their solutions.

Why my laptop won't connect to the wireless network

Before moving on to the main topic of the article, you should disassemble,. What you need to create them and how to connect to them. Everything is simple here. To organize a group, an access point is required, to which subscribers will connect. This means that the basic settings are made in the parameters of such access points. Thus, if the laptop does not connect to the Internet, then, first of all, you should check the parameters of the router.

It should be noted that in the overwhelming majority of cases, wireless routers... And, as a rule, connection problems are associated with the settings of such a device.

How a WiFi router works: Video

But, there is nothing difficult here. Absolutely everyone is able to cope with this. So, here we got to the reasons why connection problems may arise:

First of all, you need to check the settings of the router.
Driver problems.
WiFi adapter problems.
Software crashes.

Checking Router Settings

So, straight to the point. First you need to make sure that the router is turned on and working. If at the same time your laptop does not connect to Wi-Fi, then it is quite possible that the wireless connection is disabled on the router. It is very easy to enable it. We will show you how to do this using an example. Wi-Fi router D-LinkDir-615. To do this, connect to it using the cable that comes with the kit.

Next, open your favorite browser and write the IP of the router in the address bar. You can find it out in the instructions for the device, as well as on the device itself (carefully examine it from all sides). If you still cannot find the information you need, then open command line.

There are several ways to open the command prompt. If you are using Windows 8, the easiest way is to press the Windows + X key combination and select "Command Prompt (Administrator)" from the menu that appears. If Windows 7, then simultaneously press Windows + R, in the window that appears, write CMD and click "OK". In the window that opens, write the ipconfig command. Find the line "Default gateway". The values of this parameter are the IP-address we need. Typically, this is 192.168.0.1 or 192.168.1.1. But, this data may differ depending on the model of the router.

How to easily find out the IP address of your WiFi router: Video

So, we register the desired address in the browser and press "Enter". Next, you will be prompted to enter your username and password. We write - admin, admin, respectively. So we got to the router settings menu. Now at the bottom of the screen you need to click "Advanced settings". Several additional windows will appear. We are interested in a window with the name "WiFi". Here we are looking for the subsection "Basic settings". We go into it and the very first is the "Enable wireless connection" item. Here you just need to check the box.

It is worth noting that besides this there may be other problems:

The MAC address of your computer got caught in the filter.
The password was entered incorrectly (if the network requires you to enter the key).
Suspended device.

Checking Wireless Status

So, if the wireless connection is turned on, and the laptop still does not want to connect to the WiFi network, then you should check that the password was entered correctly. If you are, then we connect to the router using a cable and perform all the above steps to enter the settings menu and open the advanced parameters.

Now we are interested in "Security Settings" in the "WiFi" section. Here, the first line is network authentication (encryption type). A little lower in the line "PSK encryption key" you will see the passphrase that is used to connect. You can also change it here.

What to do if you forgot your WiFi password: Video

Checking the MAC address

Why does the Wi-Fi network on the laptop not connect when the password is entered correctly? In this case, it is worth checking the filters of the router. The fact is that to improve security, special services are used that filter out devices, allowing or denying connection to specific subscribers. First of all, we check the MAC filter.

It's in the "WiFi" section. We go into it and look at the item "Restrictions mode". As a rule, it should be disabled. But in some cases it is turned on. When it comes to home network then it's best to turn it off. If you still need it, then go to the second tab "MAC addresses" and check if your address is in the list.

It should be noted that if the MAC filter mode is set to "Allow", then your address must be in the list. If the "Deny" mode is used, then your device should not be in the list. Otherwise, you simply cannot connect your laptop to wi-fi.

The answer to the question why the WiFi network on the laptop does not connect is as follows.

Budget Wi-Fi routers like Asus, D-Link, TP-Link, Zyxel, Linksys and so on tend to freeze. This can be due to the heavy load when connecting a large number of people. Also, freezes can occur after disconnecting the device from the outlet (for example, in the event of a power outage in the house).

There may be other reasons as well. In any case, everything is solved by a simple reboot of the device. In the case of the D-Link router, everything is extremely simple. Connect to the device with a cable and enter the settings menu.

At the very top, you will see the line "System". Hover the cursor over it and select the "Restart" item in the drop-down menu.

In wi-fi TP-Link router you need to enter the section " System settings"(System tools) and select the sub-item" Reboot ". Also, in special cases, you can simply unplug the device from the outlet for at least 7-10 minutes.

Testing the wireless adapter

The router is configured correctly, but still the laptop does not catch Wi-Fi, what should I do? This means that the problem is hidden in the operating system or in the adapter itself. First of all, you should check if it is enabled. But, if you turned it off (or it did not turn on), then the computer will not see available connections at all. It is turned on by pressing the Fn key combination + the wi-fi power button (has a corresponding icon).

So, the adapter is on, but the laptop still won't connect to the WiFi network. In this case, you should check the drivers. It is worth noting that if they are not installed, then the Wi-Fi adapter will not work at all and even turn on. But sometimes, even the established software may not work properly. You can check this in the device manager.

There are several ways to open the required service. The easiest one is to press the Windows + R key combination and in the window that appears, write the command mmc devmgmt.msc. You can also find the My Computer shortcut on the desktop, in the start menu, or in the file manager (Windows Explorer). Click on the shortcut with the right mouse button and select "Properties". In the window that appears, select "Device Manager".

Here we are interested in the "Network adapters" section. We open the branch. All network devices are displayed in the list that appears:

Bluetooth module (if any).
Wi-fi adapter.
Network card and others.

We are interested in the second. As a rule, in addition to the name and model of the module itself, it is indicated by the words "Wireless Network Adapter". If this adapter is highlighted with an exclamation point in a yellow triangle, then this indicates that the software or the device itself is not working properly.

If you double-click on the adapter, a window will open in which you can find out the error code. This will fix it faster. You can also simply delete it by right-clicking and selecting the appropriate item. After that, restart your computer and reinstall the driver again.

The necessary software is contained on the disk that came with the laptop. They can also be downloaded from the official website of the laptop manufacturer.

How to Reinstall WiFi Driver in Windows 8: Video

So, the laptop does not connect to the Internet even after reinstalling the driver, what should I do?

At this stage, we should check the status of the wireless connection. To do this, click on the network icon in the tray (screen area in the lower right corner) with the right mouse button. Select a Network Sharing Center. In the window that opens, enter the "Change adapter settings" menu. Find the shortcut for the wireless network and right-click on it. We select "Properties".

In the window that appears, select the Internet Protocol version 4 (TCPIPv4) and click "Properties". Here, the markers should be set to "Obtain an IP address automatically" and "Obtain DNS server address automatically". After that, click "OK" and try to connect.

Why won't my laptop connect to the Wi-Fi network? We checked all the settings, but the connection is still missing. This indicates that diagnostics should be performed. To do this, right-click on the network icon in the tray and select "Troubleshooting". The system will automatically start searching for errors, you just have to follow the prompts on the screen.

Hello. Please help me figure out the problem. I bought a laptop (lenovo g50-45). Reinstalled the system. now I can not understand why the wi-fi does not work. The driver is standing, access points are displayed, but I cannot connect to them. I tried everything I could and knew, nothing helped. All drivers are installed except (PCI phishing / decryption controller), maybe this is the reason.

Bezprovodoff team 12/18/2015 12:40 PM

Hello. First, check what operating system is installed? Which one was originally on this laptop? What drivers did you install (where did you get them)? Maybe the drivers just don't work with your operating system. Here the reason could be anything. Every little thing can be important. When trying to connect, when a failure occurs, there is a button in the window “Troubleshooting” or “Diagnosing problems”. Have you tried this procedure? To reset all WiFi parameters, you need to run the command line with administrator rights, and run the following commands in it:

route –f.
netsh interface reset all.

netsh winsock reset.
netsh firewall reset.
After each command, press "Enter". After that, you need to restart your computer. But, I recommend that you first start the hardware manager, go to the "Network adapters" folder and remove all network adapters from it, including Wi-Fi. And only after that, launch the command line and execute the above commands. Pre-download required drivers from the official website of the manufacturer of your laptop (drivers must match your OS and its bit depth).

Bezprovodoff team 12/18/2015 12:41 PM

Hello. First, go to the Network and Sharing Center. Go to “Wireless Network Management”. Here delete the network you are trying to connect to (if any). Now, you need to download the necessary drivers (for WiFi for your laptop and your operating system). You should download the drivers from the official website of the laptop manufacturer. After that, open the hardware manager and go to the "Network adapters" folder. Remove all network adapters here (we have already downloaded the drivers for them). Now we launch the command line with administrator rights and execute the following commands in it:
netsh int ip reset (if you fail to register or an error pops up, then write like this "netsh int ip reset c: \ resetlog.txt").
route –f.
netsh interface reset all.
netsh interface ip reset resetlog.txt.
netsh interface ipv4 reset resetlog.txt.
netsh interface ipv6 reset resetlog.txt.
netsh winsock reset.
netsh firewall reset.
After each command, press "Enter". We reboot the computer. Now we are installing new drivers that we have already downloaded. That's all.

Hello. If you are using a router, then the router itself must be connected to the Internet. That is, the provider's cable is connected to the router. Next, go to the router settings and configure the WAN. There can be tons of different customization options here. For example, many people use PPPoE technology for access. In this case, you need to enter your username and password in the WAN settings. But, this may require manual settings network (IP address that your ISP gave you, subnet mask, default gateway, and so on). All this data is known only by your provider and you. Sometimes, when connecting via PPPoE protocol, you need to select Dynamic IP. That is, if your provider issues the network parameters automatically, then you only need to enter your username and password. In addition, there is a version with MAC address binding. In this case, you need to call the provider and ask him to register your router and bind it to the MAC address. Again, network settings can be automatic or manual, and Internet access can be via PPPoE or other protocol versions. Here you already need to call your provider and clarify how exactly the router is configured in your specific network. This is about the settings of the router (the question is individual and you need to take into account a lot of factors). Now for the hardware. It happens that the router itself is buggy. But, this is applicable only for older versions of routers that have been in operation for a long time. If your router is new, then it is unlikely that there are any problems with it. In any case, you must first check on the WAN and network settings, and also contact the provider. And if all the options have already been tried and at the same time it is not possible to access the Internet, then draw conclusions that the router is faulty.

Hello. First, the drivers must be installed. The fact that the system has automatically determined is still nothing to say. The system "understood" which device it is dealing with, but without drivers the device will not work correctly. The second point, if there are two WiFi adapters in the computer, then a conflict may arise between them. Again, you need to install drivers for both adapters. Also check what errors the system generates when trying to connect to the router. What errors appear when you try to go online. Describe everything in detail. The more information, the faster I can help you.

Hello. There is universal method solutions to similar problems. Try this. First, download the drivers for your WiFi adapter and network card (LAN) from the official website of the laptop manufacturer (they should be on your PC, we will come back to them later). Now start the hardware manager and find the "Network adapters" folder. Delete everything from this folder that is there (one by one, without restarting the computer). After that, run the command line with administrator rights and do what is described in this video tutorial in it (this is necessary to reset network cache and network parameters) -. After the reset, restart your computer. Now we install the drivers previously downloaded from the official website. Restart your PC again.

Hello. First, tell me how the WiFi network is organized? Are you using a router? If so, which router? Judging by the symptoms described, the problem is not limited to the computer. But also on other devices. This means that there is a problem with the access point. Accordingly, you need to look for the problem in the router. First of all, you should check if it is configured correctly WAN connection... I will not help you here, because the WAN parameters are set by your ISP (unique parameters for each). Therefore, you need to call your provider and find out how to configure the router for your network. The second step is to check the WiFi settings. There are several important points here. First, go to the basic WiFi settings. Here you need to check which WiFi mode is used. Ideally, it should be set to 802.11b \ g \ n mixed. This mode may slightly slow down the speed, but any type of device will be able to connect to such a network. Now go to settings WiFi security... Here we need to set the encryption type WPA \ WPA2 Personal, and set “Automatic” in the “Version” and “Encryption” lines (set WPA-PSK \ WPA2-PSK mixed on D-Link). If it does not help, then most likely you will have to reflash the router or even buy a new router.

Hello. If the signal is weak (the router is too far from the laptop), then the laptop will not be able to connect to the network normally. On a laptop, sometimes poor signal reception can be due to the lack of official drivers. That is, for Windows installation 8 or 10, the system itself detects all the components of the computer and no drivers are installed. But, those drivers offered by Windows do not always work correctly. In your case, you can try reinstalling the WiFi drivers. First, download the drivers for the network adapters that are on your computer (WiFi, Network Card LAN and so on). Let the drivers be on the computer, they will be needed later. Now, open the device manager and delete everything that you find there from the "Network adapters" folder. After that, open a command prompt with administrator rights ( http://owindows8.com/nastrojka/komandnaya-stroka/komandnaya-stroka-kak-rabotat.html) and execute the following commands in it - https://www.youtube.com/watch?v=T0vOyaSeY3Y... After that, restart your computer. Now install the drivers that you previously downloaded from the official website (for the installed OS, taking into account its version and bitness). Restart your PC again. If the drivers could not be found or there are problems in the search, then here is a program for you automatic installation drivers - https://goo.gl/dkxVUs.

Lenovo z500 laptop with win10 sees the network, but refuses to connect to it. all other laptops from vin7 are connected without problems. drivers on the card are native, new. this laptop connects to other wi-fi networks without problems. what is the problem? Tell me please

Hello. Please clarify. Is the network distributed through a router? What type of encryption are you installing in the router? Try changing the encryption types (encryption method) and trying to connect your tablet. That is, Install WPA-PSK and connect your tablet. If it does, try to select “WPA-PSK \ WPA2-PSK”. In general, try different options. Also try changing the broadcast channel. Try to play from the first and check different channels one by one.

team Bezprovodoff 09/08/2016 13:45

Hello. The fact that different systems are different protocols. You need to distribute the network via the command line. That is, configure the distribution on the command line. Here is an excellent article that describes three ways to share WiFi -. In your case, either setting on the command line or using the program will do Virtual Router Plus,

Hello!
Recently we changed the password to Wi-Fi, after which it was necessary to translate this same password on the laptop (not as if it was connected to the network for the first time, but through the “properties” of the network). Everything is fine with the laptop, it plows. But the parent netbook also stopped connecting, but changing the password did not solve the problem, the connection does not occur. Each time you enter the "properties", the previous password is shown. Rebooting the modem and router also did not give any new results.
I will be glad for your help.

Hello)
Hp laptop, windows 10.
Everything is fine with wi-fi, everything works. I went into the game, which after a while glitched out. Deciding to restart it, I exited and hit the shortcut again to launch it. During the launch, a screen suddenly appeared with a sad smile and a message about Windows error and that a reboot will occur. After the reboot, the wi-fi connection was lost. The wi-fi icon disappeared altogether, wherever possible. I went into the device manager, and the wi-fi adapter was already there and the trace was gone. Clicked "view - show hidden devices". Voila, my wi-fi adapter has appeared in hidden devices. Its properties say that the device is not connected, code 45.
So, the wi-fi adapter burned out like a match?

Hello! I have TOSHIBA laptop, WINDOWS 10. Problem: after “lulling” the laptop, you can connect to Wi-Fi only after I restart the router (I connect manually, it doesn't work automatically). Thanks.

Hello. You need to delete the old network, as a conflict simply arises. If Windows 7 is installed, then open the Network and Sharing Center, in the menu on the left go to the "Manage wireless networks" section, find your network here and delete it (right-click and select delete). After that, just connect to your network and the system will ask you to re-enter the password. If Windows 10 is installed, then go to "Settings" \ "Network and Internet" \ "WiFi". Here under the heading “Wireless network” there will be an inscription “Manage WiFi network settings”. Click on this inscription. Scroll down the page and here you find your old network (to which you need to change the password). Click on it with the left mouse button and select “Forget”. After that, in the usual way, reconnect to your WiFi network, and the system will ask you to enter a password. That's all. If it does not help, then reset the network parameters - https://www.youtube.com/watch?v=T0vOyaSeY3Y.

Bezprovodoff team 11/04/2016 21:52

Hello. Try this. First, remove your WiFi adapter from the computer (if it is hidden, then remove it from there). After that, run the command line with administrator rights and reset the network parameters - https://www.youtube.com/watch?v=T0vOyaSeY3Y... Reboot the computer and install the drivers for the WiFi adapter. But don't automatic update, and go to the official website of the laptop manufacturer (you can download it from another PC or from a phone or tablet, and then transfer the installation files with a flash drive) and download the drivers for your Wi-Fi adapter. After that, install the driver and restart your PC. It should work. If it does not help, then there are two options - either a virus was picked up, which damaged the registry or Host files (in this case, just reinstall the OS), or the adapter burned out. If you have a second laptop, you can try to transfer the Wi-Fi adapter from it and check if it will work. If so, buy a new adapter. If it does not work either, then reinstall the OS.

Good day. I have such a problem, I don’t understand what’s the matter, whether in a laptop or in a router, now I’ll describe the very essence of the problem. I bought an Acer E5 571G-597D laptop (the one on the sticker says) There is a connection to Wi-Fi BUT the Internet often falls into the flesh to disconnection but at the same time the wifi icon is on, the pier is connected, all the energy modes turned off everything set up * (used your site) tried it on another wifi network, so it works on another network without any interference, everywhere I was looking for a solution to this problem and I just can't find the answer, and I also did network diagnostics, nothing helps at all, through the LAN cable from the router works fine and does not want Wi-Fi, but the rest of the house also works fine from Wafai, I'm alone like a fool, I really need your help.

The power mode may need to be adjusted. This article describes how to configure the power supply for the WiFi adapter -.

Bezprovodoff team 11/17/2016 12:35 PM

Hello. Try doing a reset and reinstalling the drivers for your network equipment. that is, download the drivers for the network cards (WiFi and LAN - network card). Let the installation files be on the PC. You will need them later. Next, go to the device manager, find the "Network adapters" folder and delete everything that you find there. After that, reset the network parameters - (the command line must be run with administrator rights). Reboot your PC and install the drivers (which you downloaded beforehand). Restart your PC again. After that, everything should work properly. Remember that drivers (especially if you are using Windows 8 or 10) must be installed independently (do not update the hardware automatically), namely, download drivers for your model on the official website of the laptop manufacturer and install them yourself.

the drivers are ok

Often, after a long-awaited purchase of a brand new laptop, connecting a router for distributing WiFi, or simply completely reinstalling all the device software, the computer, for some unknown reason, cannot connect to the Wi-Fi network. Every second person finds himself in a situation where the laptop does not connect to the Internet via WiFi, and this, to put it mildly, causes discontent. The laptop simply refuses to see all kinds of Internet networks, and the special icon itself, which is located on the bottom notification panel of the device, together with the usual little white stripes, shows an exclamation mark (connection is limited) or, even worse, a red cross (a personal computer does not see networks at all).

Why won't WiFi connect on my laptop?

The reasons for this behavior of your laptop are incredibly many. In most cases, the problem lies in the fact that the special WiFi module cannot be turned on. In this case, the laptop will work and detect all networks, but during connection it will write that the operating system, unfortunately, could not connect to this network. How to solve the problem if the laptop sees WiFi but does not connect? The first step is to make sure that all of the required drivers on the so-called network adapter.

Oddly enough, this happens most often with laptops running on the Windows 7 operating system. As noted earlier, there are many reasons why your laptop cannot connect to the wireless network. Since there are so many reasons, it means there are also many ways to still force a personal computer to connect to the Internet. Is your laptop not connecting to WiFi? Windows may not have to do with it!

The laptop is not always guilty!

The problem may be not only in the PC, but also, as practice shows, in the router itself (in other words, the access point to the network). If the laptop does not connect to the Internet, then first of all, you should determine what the problem is: in the PC or in the router. How to do it? There are several ways to confirm or deny the fact that the problem is with the router, the easiest of which is to help a neighbor. Just visit your neighbor. Ask for a password from the network to check your laptop. If he can connect, then everything is in order with him, and the problem is hidden in the router. If the laptop does not connect to WiFi, writes the same thing as at home, then the problem is in the laptop.

Most likely difficulties

The most common problems with connecting a laptop or netbook to a wireless network are as follows.

WiFi does not turn on on a personal computer. This is one of the easiest problems to solve, so if you find yourself in such a situation, you should not worry - everything will work out!
The device does not detect the network of your personal router, although it sees neighbors and others. This problem is not solved as easily as the first, but still the main thing is what? The main thing is that it is being solved!
The personal computer sees all the networks, but cannot connect to any of them, while it writes: "Failed to connect." It is possible to solve this problem, because it is the most common one. Of course, it's not a fact that you can fix everything yourself, but it's worth a try, especially since there won't be any complicated actions.
The PC quickly connects to WiFi networks, but under no circumstances opens Internet pages in browsers. The problem is also more than common, you can solve it yourself, but, unfortunately, not always. You may need to call a professional technician to fix this.

Enabling WiFi on a laptop

Unfortunately, not all laptop models have default settings, which is why the laptop does not connect to the Internet via WiFi. In some situations, you still have to perform various actions in order for the laptop to connect to a particular wireless network and no longer bother its owner. This method can really help, but only for those users who have not reinstalled the Windows operating system on their computer. If you've done this before, the advice may not help. But it's worth a try!

Key combination, dedicated switch

There are laptop models in which, in order to enable the ability to connect to a wireless network, you need to press the required key combination on the keyboard. In such PCs, the first mandatory button is Fn, and the second is a special hardware key located somewhere from F1 to F12. Most often, these keys are F2, F6 and F10 - it depends on the manufacturer of the personal computer, as well as its model.

If your laptop does not belong to the ones mentioned above, then on your laptop model, the network is turned on using a small switch. The switch can be anywhere on your PC - back, bottom, side. Finding it will not be so easy, but then you just need to move the slider from "Off" to the opposite side of "On". Note: the special keys will not work if you have reinstalled the operating system. However, try it anyway - it was not. On this, your problems about the fact that WiFi does not connect on a laptop can be solved.

Turn the wireless capabilities of the laptop on and off

It is very important to know that after you have turned on the wireless adapter using special keys, you may also need to turn it on "from the inside", that is, in the operating system of the laptop itself. There are only 2 options: Windows 7 and Windows 8.

Enabling WiFi in Windows 7

If for some reason your personal laptop does not connect to WiFi, you will have to try to fix it yourself. First of all, go to the PC control panel, select "Network Management" there, then find the button "Change network adapter parameters".

For faster execution, you need to press the Win + R key, and then enter the simple command ncpa.cpl. Pay your attention to network icon if there is simply no one there, skip this point. If, nevertheless, there is a wireless network icon that is in a disabled state (that is, it has a gray color), right-click on the object, in the drop-down menu select "Enable network" or simply "Enable".

Enabling WiFi in Windows 8

Here everything is a little more complicated. If you don't understand why the laptop won't connect to WiFi, this option is worth trying.

On the right panel, select "Options", then click on "Change ...", after that you need to find the "Wireless network" button. Make sure the button is on, if not, turn it on yourself.

Now we follow all the same steps as in the Windows 7 operating system. Simply put, you must completely make sure that the ad hoc wireless connection on your computer is turned on.

Also, regardless of the OS version, you may have to turn to a program that specializes in wireless networks and WiFi connection. Almost all manufacturing companies have their own programs with the word "Wireless" or "WiFi" in the name.

Drivers

Another reason why the laptop does not connect to WiFi, writes: "Connection limited" or something like that, is the hated PC drivers. This happens especially often after the operating system has been reinstalled on a personal computer. You may have been able to reinstall Windows yourself, but you could not install the drivers from the official website of the company that created your laptop.

There are also situations when the computer automatically installs the necessary drivers after installing a new OS, but the PC itself has never done anything right. Even if you installed the drivers using some program, you still need to go to the official website of the company and download all the necessary drivers there. Only after installing them will you be able to connect to the WiFi network, if that was the case, of course.

Router

It was already mentioned above that the problem may not be in the computer, but in the router itself, which emits a signal. You can check the health of the router in several ways:

Connection limited

Such an inscription quite often pops up on laptop screens, the owners of which do not understand why WiFi is not connected on a laptop. The solution to such a problem will not take much time, but you still have to do everything exactly according to the instructions, otherwise you can "cheat".

When a person finds himself in a similar situation, panic begins: what to do if WiFi on the laptop does not connect, “Limited” is written, and you still don’t understand anything at all? Don't worry, everything can be fixed. Another thing is that not everything is on your own, but this is not such a big problem.

If you select a network in the list of available ones, then enter the password correctly (if there is one, of course), then wait for the connection ... and then a message pops up that everything is connected. But some strange icon appears on the network icon exclamation mark in a yellow triangle. Hover your mouse over this sign and the system will tell you that the connection is limited. No internet resources will work. What to do if the laptop does not connect to WiFi, or rather, it connects, but there is no Internet?

Certain problems with providers. Reinstalling the OS

The situation is that the problem may not be in the router or even in the laptop. If the connection is limited, one of the options for solving the problem is to call the technical support of the provider. Experts will try to solve this problem within a day, perhaps a little more, but after that such problems will not arise.

If in technical support claim that they do not have the problem, but you, which means that it is. In this case, when the laptop does not connect to the WiFi network (or rather, it connects, but does not work), you can repeat some of the tips that are a little higher. However, it will be easiest to call some private specialist who, for 200-300 rubles, will completely reinstall Windows for you on any one you want. He will also install all the necessary drivers for everything to work, well, and if you wish, if you ask, he can install a good antivirus.

Many more find themselves in a situation where, in fact, nothing is broken, but only a small failure occurred in the router. Don't worry, you won't have to reconnect anything, you just need to completely disconnect the router from the cables and wires for 5-10 minutes, so that it "rests" a little. After that, reconnect everything: the Internet cable and power supply. And after a couple of minutes, the laptop will automatically connect to the network (if this does not happen, do it yourself), and everything will work fine without interruption.

There is also a situation when there are no problems with anything, but suddenly WiFi stops working. What to do in this case? Either call support or restart your router. Or the problem may still be in the laptop. There will be nothing complicated in the actions: you just need to first disconnect from the network, and after a couple of minutes reconnect to it by entering the password. Everything should work, there should be no more such complaints. We hope you have received an answer to the question why the laptop does not connect to WiFi.

Wifi is becoming more and more popular every day. It completely encompassed apartments, offices and public spaces. But often different problems arise with it. In this article we will talk about why the laptop does not connect to the wifi network.

Let's consider the main reasons why the laptop does not connect to Wi-Fi

If we talk about something why the laptop doesn't connect to wifi automatically then you need to consider the main problems. There are many reasons for the lack of connection to the wifi network. We will divide them into several types:

Malfunctioning of the laptop itself.
Problems with the router.
Other problems with networks.

So let's take a closer look at each of the points.

Laptop problems

Lack of network card drivers

To use a wifi laptop, you need special drivers. They are usually present on the computer, but there are situations when the user decides to reinstall the operating system. In such cases, all drivers have to be downloaded again.

In order to check the driver, you need to go to the device manager. If you do not find the item "wireless adapter" there, then this means that you need to update the system software a little. We put the laptop on the back side and look for the model number. Next, go to the manufacturer's website and enter it. Downloading the driver wifaya and it is automatically installed. But this method is not suitable for ordinary users. Why not fits? There is an easier way. In the address bar of the browser, write "drp" or "driver booster". These are special driver packs that will automatically update your system. They are downloaded absolutely free from the manufacturer's website. Install them and run them. Next, we are looking for a button to start the update. Press and wait until all drivers are updated.

Do not forget to restart your computer after the performed operations.

The wireless adapter of the Wi-Fi network is turned off on the laptop

One of the reasons for the lack of wifi connections may be a disconnected adapter. A special light bulb is responsible for it, which looks like an antenna. You can find it on the front of your laptop. If the light is on, then the problem is not with it.

If the wireless adapter is turned off, then you need to start it. To do this, press the "fn" + "*" keys. Instead of *, you must select the button on which the antenna is drawn. It is different for all devices. After that, the light should come on. If this does not happen, then return to the item for updating drivers.

Service is not running automatic tuning WLAN

This problem occurs quite rarely, but we will consider it. First you need to go to "execute". To do this, hold down the win + r key combination. A small window appeared. Enter the line "services.msc" into it. This will open the services menu. We start the WLAN automatic configuration service. To do this, click on it with the right mouse button and click on the line "run".

After this procedure, wifi should work.

Router problems

Disabled wireless connection

First you need to make sure your router is turned on and working. After that, we check if the wireless connection is turned on. If it is turned off, then we perform the following actions:

Launch the browser.
Enter the ip of your router into the address bar. You can find it on the back of the device.
At the entrance, we indicate the username and password. The default ones are admin / admin.
Go to settings and turn on the wireless connection.
If necessary, change the ssid and key from your wifi.

After that, your device should detect the Wi-Fi.

Checking the mac address

There are times when all the data is entered correctly and the laptop sees the network, but it fails to connect. If you are faced with this, then you need to check the MAC address due to which access for some devices limited to.

We go into the settings of your router in the same way as we did in the previous paragraph. We find the parameter "mode of restrictions". It should be disabled by default. It is recommended not to use it on a home network. But if you still need it, then we check the list of blocked devices. If the mac address of your device is indicated there, then remove it from the list.

The Internet itself does not work

It is necessary to understand that wi-fi and the Internet- different processes. There are times when on a laptop writes limited access connections. In such cases, you need to go to the computer and check the Internet on it. If it doesn't work, then you won't be able to distribute it.

Also limited network access may occur immediately when starting the laptop. Don't panic, just wait a bit.

Remember that if the internet connected then this does not mean that it works.

External barriers

If you connected to the Internet, but it suddenly stopped working, then you should understand that wifi is very dependent on external factors. Walls, furniture, Appliances can greatly attenuate the signal. In such situations, you need to move the laptop closer to the router.

If you do not want to keep the devices at close range, then you need to purchase a repeater. Install and configure. After that connect to him. Thus, you will greatly increase the coverage area of the wifi signal.

Let's summarize

Reasons why it does not work wifi on laptop many. We have already told you about most of them. But there are times when wifi does not work due to a malfunction of the router or laptop itself. Try rebooting the devices, if this does not help, then contact the service center.

Wi-Fi is wireless technology new generation. Only a little time, and this method of connection to the Internet is used by millions of users around the world. Wi-Fi connection makes it possible to connect compatible devices up to fifty meters from the access point. In this case, the data exchange rate is about 150 mb / s... However, this is not all. Thanks to latest achievements in this area, speed indicators can reach several gigabits.

Every modern laptop, tablet or phone has a Wi-Fi radio module to its credit. Thanks to this, there is a significant saving in expensive operator traffic. mobile communications, and also the radio module opens access to multimedia content High Quality without having to download anything to the device. All you need is to set up a Wi-Fi connection on a portable device, set a security password and then save it to open up broad Internet access. However, sometimes not everything goes as smoothly as it seems.

Sometimes wi-fi won't connect. Why? There are a number of reasons for this, the main of which we will now discuss.

Why do problems arise?

Mostly, failures while connecting the device to a Wi-Fi network occur due to incorrect settings of the wireless router. At the same time, the laptop or tablet does not recognize the Internet connection at all. If this happened at home, you must sequentially perform a series of actions described below:

If you connect a portable device to Wi-Fi networks a popup will appear with a message "Saved, WPA-WPA2 Security", it means that the encryption on the router is incorrectly configured or the password from Wi-Fi coverage... To fix everything, you need to follow these instructions:

Check if the password is entered correctly by opening "Connection" and clicking "Change". Next, you need to select the function of displaying the password and enter it again.
If the password is entered correctly, but there is still no access, then the router settings are problematic.

If the settings are incorrect, you must:

Outcome

So now your laptop, tablet or smartphone should connect to Wi-Fi. In this case, the initial connection of the device with the router will be broken, you need to reconnect. As for encryption issues, in these cases it is also necessary to proceed step by step:

You need to go to the "Settings" of the router, select the item "Network Security" - the sub-item "WEP", "WPA / WPA2", and then enter a password that will help the router to recognize the user. You will understand which item to choose from the error message, or you can experiment yourself.
Next, you need to save the settings using the appropriate function, and then reboot the router.

These are, perhaps, all the main actions that you can do at this stage. In other cases, it is better to contact a specialist for a more accurate setting.
