Reinstalled Windows no wifi. Turn on Wi-Fi using keys and a hardware switch

The Internet after reinstalling windows 7 may not work for a number of reasons:

• Removed during reinstallation software for network equipment;
• The provider erroneously blocks the connection, believing that access is being denied from someone else's computer under your credentials.

Check if the services of the provider are paid!!!

The first can be caused by the fact of formatting hard drive during installation. The base software package may not be suitable for the network equipment you are using. Often, certain builds of windows 7 do not include the drivers required to work on the Internet.

In the second scenario, in order to restore the connection and stabilize the Internet after Windows installation, you will need to contact the contact phone number of the service provider. The technical support of the provider should solve the problem as soon as possible.

So after reinstalling windows 7 internet not working. Before starting the study of the software part, we will exclude the probable malfunctions of the technical part. To this end, it is recommended to check the operation network card:

• If the special indicator light in the card slot is on, then the card is OK;
• When the indicator is "silent", it is recommended to check for a cable breakdown or check the card itself - it may be faulty.

If after installation new version The OS does not have Internet, then it is important to check the wifi module - a router or a modem (if access to network resources is carried out through it):

• Equipment activity can also be examined by checking the indicator lights. If a special diode on the laptop keyboard is active or the system clock indicator in the lower right corner is in order, then the router is functioning stably;
• For modems, the situation is similar.

Important!!! Check Ethernet controller driver

To connect the Internet, missing after clean install OS, you can choose two ways:

• Use the disk containing the basic software for network equipment. Such a disk must be available after the purchase of the computer;
• You can also install software downloaded by using another computer or laptop. If you plan to set up a laptop, then its name and model are driven into the search engine. To find drivers on a PC, you only need the model and company that released the motherboard.

The best option is to visit the website of the laptop manufacturer or motherboard or the Ethernet controller itself (network card).

By selecting drivers, you can

Regarding the setting

After installing all the necessary driver packages and checking for serviceability or malfunction of network equipment, the question of how to set up the Internet becomes urgent.

If the connection is made directly: a cable is plugged into the corresponding socket on the back of the PC, then it is recommended to follow the instructions:

• Through me, "Start" refers to the "Control Panel";
• Now through the "Network and Sharing Center" we turn to "Setting up a new connection";
• A window will appear on the monitor with options and types of connections. When an ADSL connection is made, you will need to select "Connect to the Internet". When you plan to connect via 3G, the choice should be made in favor of "Telephone connection settings".

For the first case, after selecting "Internet Connections", we turn to the "High-speed" type. Enter all required values. If the hardware is working properly and the software elements are installed correctly, then the connection will acquire the “ready to use” status.

Further, for convenience, it is recommended to create a shortcut and place it in a place convenient for access. Through the "Control Panel" we turn to the "Network and Sharing Center", then to "Change adapter settings". By selecting a newly configured connection and referring to its properties, we create the required shortcut.

The images show how to enter the "Device Manager"

enter the command devmgmt.msc >>> Enter

Setting up a router

If Internet resources are accessed via Wi-Fi, and a computer with reinstalled windows for some reason does not see an active connection, then the main and main task of the PC user is to find the software for the network card or directly the module that distributes the signal. We talked about how to do this better at the beginning of the article.

If you have no experience with router settings various models and suppliers, it is recommended to first study the relevant materials or enlist the support of the wizard: there are often situations when, after reinstalling the OS, for one reason or another, the wi-fi module settings are lost.

More detailed information about self setting routers of various models

Modem users

Brief instructions on how to connect a USB modem:

• USB devices must be connected to a computer or laptop strictly after turning on and waiting for a full boot;
• After some waiting, the system will issue an interactive notification about the discovery of new equipment;
• Next, the computer will prompt the user to install an environment that allows unhindered work with the modem.

Modern models are created by service providers in such a way that all the necessary services - auto tuning and dynamic IP address are already embedded in the device. This means that the user does not need to perform additional manipulations. However, a situation may arise when the network does not appear on a working computer after connecting the USB modem. In this case, it is recommended to study the accompanying documentation or contact the service directly. technical support service provider.

Summing up

In this article, we examined the most common scenarios for the behavior of network equipment after a clean installation of Windows 7. It is worth noting: often many users can freely connect to Internet resources, while others encounter difficulties, the solution of which is described by us in the material of the article.

In conclusion, we recommend users to download in advance, save and update regularly Driver program Pack solution. Its peculiarity lies in the fact that it is able to search for and install drivers that are missing on the PC. An alternative to action is storage removable media most needed and current versions Software not only for network equipment, but also for all other nodes of your personal computer or laptop.

Good day.

When installing new Windows, as a rule, the system automatically adjusts many parameters (will put universal drivers, will set the optimal firewall configuration, etc.) .

But it just so happened that some moments when reinstalling Windows are not automatically configured. And, many who reinstalled the OS for the first time are faced with one unpleasant thing - the Internet is not working.

In this article I want to analyze the main reasons why this happens, and what to do about it. (especially since there are always a lot of questions regarding this topic) …

The most common reason for no internet (note after installing a new Windows OS) - this is the absence of a network card driver in the system. Those. the reason is that the network card just doesn't work...

In this case, a vicious circle is obtained: there is no internet, because there is no driver, but you can’t download the driver - because no Internet ! If you do not have a phone with Internet access (or another PC), then most likely you cannot do without the help of a good neighbor (friend) ...

Usually, if the problem is with the driver- then you will see something like the following picture: a red cross will light up above the network icon, and an inscription something similar to this: "Not Connected: No connections available"…

In this case, I also recommend going to panel Windows controls , then open the section Network and Internet, then Network and Sharing Center.

In the control center - on the right there will be a tab " Change adapter settings"- it must be opened.

In network connections, you will see your adapters that have drivers installed. As you can see in the screenshot below, my laptop does not have a driver for wifi adapter a (there is only ethernet adapter, and that one is disabled).

By the way, check if you have the driver installed, but the adapter itself is simply turned off (as in the screenshot below - it will just be gray and it will say: “Disabled”). In this case, just turn it on by right-clicking on it and selecting the appropriate one from the pop-up context menu.

Network connections

I also recommend taking a look at device Manager: there you can see in detail which equipment has drivers, and which ones do not. Also, if there is a problem with the driver (for example, it does not work correctly), then the device manager marks such equipment with yellow exclamation marks ...

To open it, do the following:

• Windows 7 - in the run line (in the START menu), paste devmgmt.msc and press ENTER.
• Windows 8, 10 - press the WIN + R key combination, paste devmgmt.msc and press ENTER (screenshot below).

In Device Manager, open the " Network adapters ". If your equipment is not in the list, then there are no drivers in the Windows system, which means that the equipment will not work ...

How to solve the problem with the driver?

1. Option number 1- try updating the hardware configuration (in device manager: just right click on the title network adapters and in the pop-up context menu, select the desired option. screenshot below).
2. Option number 2- if the previous option did not help, you can use the special utility 3DP Net (It weighs about 30-50 MB, which means it can be downloaded even using a phone. In addition, it works without an Internet connection. I talked about it in more detail here :);
3. Option number 3 - download on the computer of a friend, neighbor, friend, etc. special driver package - iso image to ~10-14 GB, and then run it on your PC. There are a lot of such packages on the net, I personally recommend Driver Pack Solutions (link to it here: );
4. Option number 4 - if nothing from the previous one worked out and did not give results, I recommend looking for a driver by VID and PID. In order not to paint everything in detail here, I will give a link to my article:

And this is how the tab will look like when the driver for the Wi-Fi adapter is found (screenshot below).

If you can't connect to the network after updating the driver...

In my case, for example, Windows refused to search for available networks, and after installing and updating the drivers, the error and the icon with a red cross were still given.

The Troubleshooter will then automatically begin troubleshooting network unavailability issues and advise you every step of the way. After the button has been pressed "Show list of available networks" - the troubleshooting wizard configured the network accordingly and all available WiFi networks became visible.

Actually, the last touch remains - select your network (or the network from which you have a password to access :)), and connect to it. Which is what was done...

Entering data to connect to the network ... (clickable)

2. Network adapter disconnected / Network cable not connected

Another common reason for the lack of Internet is a disabled network adapter (with a driver installed). To check this, you need to open the tab (which will show all network adapters that are installed in the PC and which have drivers in the OS) .

The easiest way to open is to press the buttons together WIN+R and enter ncpa.cpl (then press ENTER. In Windows 7 - the run line is located in START) .

Opening the Network Connections tab in Windows 10

In the opened tab network connections- pay attention to the adapters that are displayed in gray (i.e. colorless). Next to them will also show off the inscription: "Disabled".

Important ! If there is nothing at all in the list of adapters (or there is no adapter that you are looking for) - most likely you simply do not have the necessary driver in your system (the first part of this article is devoted to this).

To enable such an adapter - just right-click on it and in context menu select "Enable" (screenshot below).

After the adapter is turned on, pay attention if there are any red crosses on it. As a rule, the reason will even be indicated next to the cross, for example, in the screenshot below “Network cable is not connected”.

3. Wrong settings: IP, default gateway, DNS, etc.

Some ISPs require you to manually set certain TCP/IP settings (this applies to those who do not have, in which they brought these settings once, and then you can reinstall Windows at least 100 times :)) .

You can find out if this is so in the documents that the Internet provider gave you when concluding the contract. Usually, they always indicate all the settings for accessing the Internet. (In extreme cases, you can call and clarify in support).

Everything is set up quite simply. AT network connections (how to enter this tab is described above, in the previous step of the article) , select your adapter and go to its properties.

Ethernet network adapter properties

In the properties, you need to specify the data that the Internet provider provides you, for example:

• IP address;
• Subnet mask;
• main gateway;
• DNS server.

If the provider does not specify these data, and you have some unfamiliar IP addresses set in your properties and the Internet does not work, then I recommend that you simply set the receipt of the IP address and DNS automatically (screenshot above).

4. PPPOE connection not created (as an example)

Most ISPs organize Internet access using the PPPOE protocol. And, say, if you do not have a router, then after reinstalling windows- your old configured connection to connect to the PPPOE network will be deleted. Those. need to recreate it...

To do this, go to windows control panel at the following address: Control Panel\Network and Internet\Network and Sharing Center

Then select the first masonry " Connecting to the Internet (Setting Up a Broadband or Dial-Up Internet Connection)” and click next.

Then choose " High Speed ​​(with PPPOE) (Connection via DSL or cable requiring username and password)"(screenshot below).

Then you need to enter your login and password to access the Internet (this data must be in the contract with the Internet provider) . By the way, please note that in this step you can immediately allow other users to use the Internet by ticking just one checkbox.

Actually, you just have to wait until Windows establishes a connection and use the Internet.

PS

Let me give you one last piece of advice. If you are reinstalling Windows (especially not yourself) - do backup files and drivers - . At the very least, you will be insured against cases when there is not even an Internet connection to download or look for other drivers (you must admit that the situation is not pleasant).

For additions on the topic - a separate merci. That's all for now, good luck to everyone!

Wifi not working on laptop? Then you have come to the right place.

There are quite a few reasons why a laptop cannot connect to a Wi-Fi network. This article will provide an algorithm for solving this problem, taking into account the frequency of possible causes.

Step 1: Diagnose the source of the problem

In case of unsuccessful connection to wireless network, the problem may not be in the client device at all (, netbook, ultrabook, etc.), but in the settings of the router.

To do this, you need to try to connect to a wireless network using any other device equipped with a Wi-Fi module - another laptop, netbook, tablet, smartphone, etc.

If you were able to connect to the wireless network, the problem is with your computer. If the connection fails, the problem is in the .

Step 2. Hardware enable laptop Wi-Fi module

So, based on the diagnostics that we ran in the previous step, it was determined that the connection problem occurred on one of the client devices of the wireless network.

As a rule, all laptops are equipped with indicator lights. wireless module and have a specific key combination to turn it on.

Note! A glowing indicator indicates that the adapter is on. The absence of backlight indicates that the Wi-Fi adapter is turned off.

Most manufacturers place indicator lights on the front or one of the sides of the computer.

Less common is the location of indicators near the touchpad or on the monitor case.

On some HP models, the module status indicator light may be built into the power button on the keyboard.

To enable WiFi module key combination is used, which consists of special key Fn and one of the system keys F1 to F12 .

Look carefully at the system (functional) keys and find the Wi-Fi connection icon on one of them.

On some older models, in particular, from the company, you can find a solution for turning on the Wi-Fi module in the form of a two-position switch.

Such a switch, as a rule, is located on one of the sides of the laptop or on its front side.

Below is a list of keys that you can use to enable / disable the Wi-Fi module on the most popular brands of laptops.

Acer: Fn+F3

ASUS: Fn+F2

Dell: Fn + F2

Fujitsu: Fn + F5

Gigabyte: Fn + F2

HP: Fn+F12

After hardware enable adapter, connect to the wireless network. If the connection fails, go to the next step.

Step 3. Programmatically enable the laptop's Wi-Fi module

In addition to the hardware enablement of the wireless adapter, which we dealt with in previous paragraph, there is also a software inclusion that runs directly in the operating system installed on the laptop.

To enable the wireless connection adapter in Windows 7, you must perform the following steps: on the notification panel (near the clock), select the Internet connection status icon "Network and Sharing Center".

In the left column, select "Change adapter settings".

In the list of connections, you need to pay attention to the indication of the item "Wireless network connection". If the adapter is disabled, it will not be highlighted.

To enable, right-click on the icon and select enable.

The color of the icon should change.

Now you need to pay attention to the notification bar area. In the first case, the laptop's Wi-Fi adapter is turned on, but there is no network to connect to (usually this is a router problem).

In the second option, the adapter is turned on and you need to find your network in the list of connections and connect.

After enabling the adapter programmatically, we try to connect to the . If the connection fails, go to the next step.

Step 4. Installing/reinstalling drivers for the Wi-Fi module

To check if the driver is installed, right-click on the "My Computer" shortcut, which can be found either in the "Start" menu or on the Desktop, select "Properties" in the context menu, select the "Manager" menu in the left column of the window that opens. devices."

In the window that opens, you need to find the "Network Adapters" menu and find the name of the wireless adapter, which contains part of the name "... Wireless Network Adapter" or "Wireless Network Adapter ...", where instead of "..." should be the name of your wireless adapter, for example, Atheros , Realtek, Qualcomm.

In our case, this is the Atheros Wireless Network Adapter. Right-click on it, select "Properties". In the menu that opens, you need to make sure that "The device is working properly."

Important! If you did not find the name in the "Network Adapters" menu, you need to install drivers. Drivers can be found on the disk that came with the laptop, or by searching the Internet.

Step 5: Troubleshoot connection problems in the router

In the first step of our article, we looked at how to determine with a high degree of probability possible cause which makes it impossible to establish a Wi-Fi connection.

Since there are quite a lot of routers, and even more firmware for them, in this paragraph, general recommendations will be given on how to fix the problem.

1. Try to reduce the distance between and the router. Try to ensure that there is a direct line of sight between devices and as little interference as possible (walls, partitions, ceilings, microwave ovens, radiotelephone bases, etc.).

What to do if Wi-Fi does not work on a laptop

Why is Wi-Fi not working on my laptop? You can find out by running system diagnostics. You will learn how to do this in the video below.

The problem when the Internet does not work after reinstalling Windows can occur not only in Windows 7, but also in Windows 8 and Windows 10. I will try to prepare a separate article about solving this problem on the "top ten". In addition, I already wrote how to set up the Internet in Windows 10. It is enough to follow a few tips from the article, and the Internet on your computer will work again.

And in this article, we will look at solutions to the problem when you (or someone else) installed on a computer, or windows laptop 7, everything turned out and everything works, but there is no internet connection. There can be a lot of different nuances. Since there are many ways to connect to the internet. Therefore, the solutions will also be different. Looking ahead, I’ll say that most likely you just need to install the necessary drivers, or set up an Internet connection (or both). Because, right after installation, Windows 7 almost never installs a driver for a Wi-Fi adapter. This means that Wi-Fi will not work after installing Windows 7. Well, if you have set up an Internet connection, then of course you need to set it up again.

It all depends on the connection method, and in some cases on the Internet provider. We will consider the following options:

• Wi-Fi not working after installing Windows. In almost all cases, simply installing the wireless adapter driver is sufficient. Windows 10 already installs the Wi-Fi driver on its own (In most cases), but Windows 7 lags behind in this regard.
• If the Internet does not work via cable from the router. Again, it all depends on the symptom. It may also be that the system was unable to install the network card driver. You need to check, and if necessary, then install it.
• If a connection to the provider was previously configured (high speed) and after reinstalling Windows 7 it is gone. It's quite normal. It is advisable to first check if there are any problems with the network card driver, then simply create a connection to the provider.
• And if you have Internet via a 3G USB modem, then you must definitely install the modem driver, and again, set up a connection to the provider.

Now we will understand everything in more detail, and solve problems with connecting to the Internet after installing or reinstalling the operating system.

Why doesn't Wi-Fi work after installing Windows 7?

And so, we installed Windows, we look at the Internet connection icon, but it is not the same as it was before. There are no Wi-Fi networks available for connection, and we cannot connect to the Internet via Wi-Fi. Most likely, the connection status will be like this (when network cable is not connected):

The problem is that there is no Wi-Fi at all. There are no networks available, and most likely you won't even see a wireless adapter. And all because Windows 7 simply could not install the driver on the wireless adapter that is installed in your laptop, and which is responsible for Wi-Fi. How many times have I reinstalled Windows 7 to different laptops, and the Wireless adapter driver always had to be installed manually.

It is very easy to check this. Just go to device manager and see. You can open it different ways. The simplest: open the start, insert into the search bar mmc devmgmt.msc, press Enter. Or through "Run". You can still through the "Computer" - "Properties" - "Device Manager".

In the manager, we are looking for a tab Network adapters. And there should be an adapter, in the name of which there is "Wireless", or "Wi-Fi". Like this:

If you don't have such an adapter, or you have one, but with a yellow exclamation mark and the status "The device is not working properly", then this means that you just need to install the necessary driver, and everything will work. In this case, in the device manager, there must be at least one " unknown device". This is our Wireless adapter.

The main thing is to install the driver for your laptop model (adapter), and for Windows 7 (in our case). I will not write about it in detail here. Has already detailed instructions about how to install drivers for a Wi-Fi adapter in Windows 7. After installation, you will be able to connect to Wi-Fi networks.

Cable internet not working after reinstalling Windows 7

If you have an internet connection with network cable from a router, or directly from an Internet provider, but without any settings, when you do not need to create a connection, then first of all we check the network card driver. It also happens that Windows 7 cannot install it either. This is the case when the computer does not respond to the cable connection (icon does not change). And if he sees the connection, but it is "Without access to the Internet", then see this article. But this is unlikely.

And so, go to the device manager (how to enter, wrote above), and on the same "Network adapters" tab we should have a network card. I have this "Realtek PCIe GBE Family Controller". Your name may be different. It all depends on the manufacturer.

If you do not see a network card adapter there, then as in the case of wireless adapter you need to install the driver. If you have a laptop, then by model we search on the manufacturer's website and install the driver for the LAN adapter. You can search by the name of the adapter itself. Also, the driver is on the disk that may have been bundled with your computer.

Well, check all the cables, maybe you are connecting something incorrectly.

Lost high-speed connection to the provider on the laptop after reinstalling Windows 7

In this case, you just need to create this connection again. Connect the cable from the provider to the network card of the computer (it is most likely already connected). If the computer does not respond to the cable, or you cannot create a high-speed connection, then check if everything is in order with the network card driver. Wrote about it above.

To create a connection to an ISP, click on the Internet connection icon, and select "Network and Sharing Center". Then click on "Set up a new connection or network".

Select "Connect to the Internet" and click "Next".

Select "High Speed ​​(with PPPoE)".

Enter the username, password, optionally check the box "Remember this password", you can change the name of the connection, and click on the "Connect" button.

Connection data: username and password, issued by the provider. If you still need to register IP and DNS addresses, then you can do this by following this instruction, in the properties of the "Local Area Connection" adapter.

Internet does not work via 3G USB modem after installing Windows

As in the case of other connections, you need to install the necessary driver for the modem, and configure telephone connection to the operator. It is already difficult to give specific advice here, since everyone has different modems, and different operators. You can see the instructions for setting up a connection via a 3G modem using the example of an Intertelecom provider.

Installing the 3G/4G modem driver

Everything is simple here. The driver may be on a disk that you may have been given when you connected to the Internet. There are many modems where the driver is built into the modem itself. To check, connect the modem to the computer, and go to "My Computer" (just "Computer" in Windows 7). There may be a drive, or a disk drive that appears after connecting the modem. Tear it off and run the driver installation. Sometimes, the offer to install the software appears immediately after connecting the modem.

If these methods do not fit, then we look at the modem model, and look for a driver on the Internet. On the website of your operator, there should also be the necessary drivers.

Setting up a telephone connection

As you deal with the drivers, you need to create a connection. I don’t know how it is with all operators (Beeline, Yota, MegaFon, etc.), but with Intertelcom, you need to create a regular telephone connection with a number, username and password.

To create it, go to "Network and Sharing Center", and select "Set up a new connection or network" (see screenshots above). Next, select "Setting up a telephone connection."

Specify the required parameters provided by the provider (number, username, password). The computer will be connected to the Internet and a connection will be created. If an error appears that "Windows cannot detect the modem", then check the modem driver. Or, for starters, just restart your computer.

This guide details why a Wi-Fi connection may not work on a laptop in Windows 10, 8, and Windows 7. The following step-by-step describes the most common scenarios related to the health of a wireless network and how to solve them.

Most often problems with WiFi connection, expressed in the absence of available networks or access to the Internet after connecting, occur after updating or installing (reinstalling) the system on a laptop, updating drivers, installing third party programs(especially antiviruses or firewalls). However, there are other situations that also lead to these problems.

The material will consider the following main options for the “Wi-Fi does not work” situation in Windows:

1. I can't turn on Wi-Fi on my laptop (red cross on the connection, message that there are no connections available)
2. The laptop does not see the Wi-Fi network of your router, while it sees other networks
3. The laptop sees the network, but does not connect to it
4. The laptop connects to a Wi-Fi network, but pages and sites do not open

In my opinion, I have indicated all the most likely problems that may arise when connecting a laptop to a wireless network, let's start solving these problems.

How to turn on Wi-Fi on a laptop

Far from all laptops, the wireless network module is enabled by default: in some cases, you need to perform certain actions in order for it to work. It is worth noting here that everything described in this section is fully applicable only if you did not reinstall Windows, replacing the one that was installed by the manufacturer. If you did this, then some of what will be written about now may not work, in this case - read the article further, I will try to take into account all the options.

Turn on Wi-Fi using keys and a hardware switch

On many laptops, in order to enable the ability to connect to wireless wifi networks, you need to press a combination of keys, a single key, or use a hardware switch.

In the first case, to turn on Wi-Fi, either just a function key on the laptop is used, or a two-key combination - Fn + Wi-Fi enable button (may have an image of the Wi-Fi emblem, radio antenna, airplane).

In the second one, there is just an “On” - “Off” switch, which can be located in different places on the computer and look different (you can see an example of such a switch in the photo below).

Concerning function keys on a laptop to enable a wireless network, it is important to understand one nuance: if you reinstalled Windows on a laptop (or updated it, reset it) and didn’t bother installing all official drivers from the manufacturer’s website (but used a driver pack or Windows build, which supposedly installs all the drivers), these keys will most likely not work, which may lead to the inability to turn on Wi-Fi.

To find out if this is the case, try using other actions provided by the top keys on your laptop (just keep in mind that volume and brightness can work without drivers in Windows 10 and 8). If they also do not work, apparently, the reason is just the function keys.

Usually not even drivers are required, but special utilities, available on the official website of the laptop manufacturer and responsible for the operation of specific hardware (which includes function keys), for example, HP Software Framework and HP UEFI Support Environment for Pavilion, ATKACPI driver and hotkey-related utilities for Asus laptops, function key utility and Enaergy Management for Lenovo and others. If you don't know what specific utility or driver is required, search the Internet for information about this in relation to your laptop model (or tell the model in the comments, I will try to answer).

Enable wireless networking in Windows 10, 8, and Windows 7 operating systems

In addition to turning on the Wi-Fi adapter with the laptop keys, you may need to turn it on in the operating system. Let's see how the wireless network is turned on in Windows latest versions.

In Windows 10, click the network connection icon in the notification area and make sure the Wi-Fi button is on and the Airplane mode button is off.

In addition, in latest version OS turning the wireless network on and off is available in Settings - Network and Internet - Wi-Fi.

In Windows 7 (however, this can also be done in Windows 10), go to the network and sharing center, select "Change adapter settings" on the left (you can also press the Win + R keys and enter the ncpa.cpl command to get into the list of connections ) and pay attention to the wireless network icon (if it is not there, you can skip this section of the instructions and proceed to the next one, about installing drivers). If the wireless network is in the Disabled (Grey) state, right-click the icon and click Enable.

In Windows 8, it's best to do the following and do two things (because two settings, according to observations, can work independently of each other - on in one place, off in the other):

1. In the right panel, select "Settings" - "Change PC settings", then select "Wireless Network" and make sure it is turned on.
2. Perform all the steps that are described for Windows 7, ie. make sure the wireless connection is enabled in the list of connections.

Another action that may be needed for laptops with pre-installed Windows OS (regardless of version): run the program for managing wireless networks from the laptop manufacturer. Almost every laptop with pre-installed operating system there is also a program that contains Wireless or Wi-Fi in the name. In it, you can also switch the state of the adapter. This program can be found in the Start menu or All Programs, and it can also add a shortcut to the Windows Control Panel.

The last scenario - you reinstalled Windows, but did not install the drivers from the official site. Even if the driversWi-Fi installed automatically during installation Windows, or you installed them using a driver pack, and in the device manager it shows “The device is working fine” - go to the official website and get the drivers from there - in most cases this solves the problem.

Wi-Fi is on, but the laptop does not see or connect to the network

In almost 80% of cases (from personal experience), the reason for this behavior is the lack of the necessary drivers for Wi-Fi, which is a consequence of reinstalling Windows on a laptop.

After you have reinstalled Windows, there are five options for events and your actions:

• Everything was determined automatically, you are working on a laptop.
• You install individual drivers that are undecided from the official site.
• Are you using the driver pack for automatic installation drivers.
• Something from the devices was not defined, well, okay.
• Without exception, all drivers are taken from the official website of the manufacturer.

In the first four cases, the Wi-Fi adapter may not work as it should, even if the device manager shows that it is working properly. In the fourth case, it is possible that wireless device does not exist in the system at all (i.e. Windows does not know about it, although it physically exists). In all these cases, the solution is to install drivers from the manufacturer's website (link - addresses where you can download official drivers for popular brands)

How to find out which Wi-Fi driver is on your computer

At any Windows versions, press the Win + R keys on your keyboard and enter the command devmgmt.msc, then click OK. The Windows Device Manager opens.

Open the "Network adapters" item and find your Wi-Fi adapter in the list. Usually, it has the words Wireless or Wi-Fi in the name. Right-click on it and select "Properties".

In the window that opens, open the "Driver" tab. Pay attention to the items "Driver Provider" and "Date of Development". If the supplier is Microsoft, and the date is several years away from today, go ahead to the official website of the laptop. How to download the driver from there is described at the link I gave above.

Update 2016: In Windows 10, the reverse is possible - you install the right drivers, and the system itself “updates” them to less efficient ones. In this case, you can roll back the Wi-Fi driver in the device manager (or by downloading it from the official website of the laptop manufacturer), and then disable automatic update this driver.

After installing the drivers, you may need to enable the wireless network, as described in the first part of the instructions.

Additional reasons why the laptop may not connect to Wi-Fi or see the network

In addition to the options described above, there may be other reasons for problems with the Wi-Fi network. Very often - the problem is that the wireless network settings have changed, less often - that it is not possible to use a certain channel or wireless network standard. Some of these problems have already been described on the site earlier.

In addition to the situations described in these articles, others are possible, it is worth trying in the router settings:

• Change channel from "auto" to specific, try different channels.
• Change the type and frequency of the wireless network.
• Make sure that Cyrillic characters are not used for the password and SSID name.
• Change the network region from Russia to the USA.

That's about all I can offer on this subject. I'll remember something else, I'll add instructions.

The laptop connects via Wi-Fi but the sites do not open

If a laptop (as well as a tablet and a phone) connects to Wi-Fi but the pages do not open, there are two options:

• You have not configured the router (at the same time, everything can work on a stationary computer, since, in fact, the router is not involved, despite the fact that the wires are connected through it), in this case, you only need to configure the router.

That, perhaps, is all, I think among all this information you will be able to extract for yourself exactly what is right for your situation.
