The netbook does not connect to the wifi router. Why won't my laptop connect to WiFi?! Complete lack of wifi

“I can’t connect to my WiFi” - topics with a similar name appear on various computer forums almost every day. And this is not at all accidental, because problems with wireless connections occur quite often. What could be the problem and how to solve it in this or that situation?

Check your internet connection

Before taking any action, make sure that the cable transmits the Internet. To do this, connect your computer to the modem or router directly using a wire. There is always a possibility that the problem comes from the provider (for example, by conducting engineering works, they typically cut off network access for users for several hours).

Checking if all devices are connected

Before asking the experts “what should I do if I can’t connect to my WiFi”, make sure that network hardware is in an active state. First, the Wi-Fi indicator on the router itself should be lit. If the network is not enabled, you should enter the IP number (192.168.1.1 or 192.168.0.1) into the browser and connect it. You should also make sure that the appropriate adapter is enabled on the computer or laptop itself. This can be done through the Network and Sharing Center. Access" Windows (go to the tab responsible for the adapter settings and find the one that supports wireless connections). On some models laptop wifi turns on by pressing a certain button. You can try restarting your computer and trying to turn on the adapter again. If this does not help, you will most likely need to. If even reinstalling the driver did not help, you may need to reinstall the operating system.

If the computer “sees” Wi-Fi, but gives an error when trying to connect

“I did everything above, but I still can’t connect to my WiFi.” If your computer displays information about available networks, but an error message appears on the screen when you try to connect, the problem may be related to wrong mode router operation. Let's move on to its settings (you already know how to do this from previous paragraph) and change the mode from standard to mixed (Mixed), B/G/N or B/G.

Network without Internet access

This is perhaps one of the most common problems why WiFi won’t connect. Windows 8, by the way, is much more susceptible to this than previous versions OS. This happens because the computer receives an incorrect IP address or address DNS servers. First you need to find out what exactly is wrong. To do this, open the list available networks, click right click mouse on the one to which we want to connect, and select the “Status” item. If an IP address was not received or an incorrect one was received, next to the “IPv4 connection” line there will be a message stating that there is no access to the network. You can check this by opening “Change adapter settings” in the Network and Sharing Center. Having found your wireless connection, right-click on it and open properties, and then look at the IPv4 protocol. If any addresses are specified in the settings, write them down on a separate sheet (they may still be needed), and then change the options so that the IP address and DNS server address are obtained automatically. Confirm the changes made and check your Internet access. If this does not help, restore the default addresses used by the router.

Problems associated with incorrect addresses DNS servers also cause the Internet to not connect via WiFi. As in the previous case, they are displayed in the status window wireless network. In this case, next to the “IPv4 connection” line you will see the inscription “Without Internet access”. This can be corrected, again, in the protocol settings. Try installing automatic receipt required addresses or enter “8.8.8.8” in the preferred DNS server column, and “77.88.8.8” in the alternative DNS server column (public addresses of Yandex and Google DNS servers).

We hope this article helped you, and the need to write to specialists with the question “why can’t connect to my WiFi” is no longer necessary for you!

Today we will try to figure it out actual question– loss of Wi-Fi network. Almost everyone has encountered this situation and asked themselves the question of why the laptop does not connect to the Internet via a wireless connection.

There may be several reasons for the failure, as well as solutions to this situation.

We will discuss different solutions to this problem in detail in this article.

Let's say Wi-Fi is connected to the laptop, but there is no Internet. There may be several reasons for this problem:

1. Problems with the access point (the router is out of order, the provider is performing technical work);
2. Problems with the device (Wi-Fi on the device is faulty, the drivers have crashed).

Different devices display fault statuses differently. On a laptop, the Wi-Fi network status bar may display Exclamation point, which indicates a connection failure.

On Android devices wifi icon changes its color from blue to gray.

Regardless of the type of warning, you should check the functionality of your Internet connection using a browser. If there is no Internet, an error will appear.

How to connect the Internet to a laptop via Wi-Fi

Connecting a PC occurs in several stages:

Now go to the browser to check:

Everything works, which means the connection was successful.

Operating system Windows 10

On computers with OS Windows connection it's a little easier:

What should I do if there is no network icon on the panel?

Sometimes there is a situation in which wifi icon absent. In this case, you need to do the following:

• Open “Control Panel”;
• Go to “Network and Internet” / “Network and Sharing Center” shared access»;
• Go to “Change adapter settings”.

There will be several connections in the window that appears. You must select “Wireless Network” and right-click on it.

Select “Enable” from the drop-down menu. After this, the icon will appear on the bottom panel.

Lack of drivers

Another reason for the absence of an icon may be driver incompatibility or incorrect installation. This problem is quite rare and can be solved by reinstalling the drivers that come with the laptop. The process is automatic. After starting the disk, the system itself will offer to install necessary drivers.

Error: "Windows could not connect to Wi-Fi"

The most common problem occurred in laptops with Windows version 8 and 10. If your network flatly refuses to work, try connecting to another network. For example, from friends, or share the connection from a mobile device using modem mode. This method will help determine the malfunction.

If the connection is successful, you can diagnose a laptop malfunction. This means that the cause of the problem is in the router itself.

You should check the connection to the router from another device. If you successfully connect another device, you should check the IP addresses of the laptop. To do this, in “Change adapter settings” you need to right-click on “Wireless Network” and select “Properties”.

The correctness of the connection can be determined by the packets sent and received. If one of these areas has a value equal to “0,” then there is an obvious conflict between the IP addresses or the devices themselves.

The solution to this problem is to switch the device to automatically receive IP addresses. In 99% of cases, the problem is resolved after applying the parameter.

But, if there is no connection on all devices, you should blame the router. First, you should try updating your device, if you have one. a new version firmware. You can call technical support manufacturer. They will be happy to help you update your gadget.

If the update does not help, then you should contact service center. The average lifespan of a router is about 5 years. After this period, it is recommended to replace the device.

Device incompatibility

Currently, this phenomenon is extremely rare, but still occurs. The reason for this is the manufacturer, who initially does not specify correct algorithm compatibility for various devices. There may be no connection on the PC, and mobile phone connect easily. The reason is the incompatibility of devices. Updating drivers or installing a patch that will allow you to use the device without problems will help eliminate the lack of Internet.

Drivers

But the problem with drivers is not uncommon. Outdated drivers Computer adapters can create many connection problems. You can update drivers in several ways:

• By using support program. Driver Pack Online – popular program for Windows, designed to solve driver problems. It automatically finds all the necessary drivers, downloads them and installs them at the user's request. The program interface is simple and intuitive. The program is absolutely free.
• With the help of an assistant Windows updates. He helps in automatic mode find and install updates. But it has some disadvantages:

1. Limited number of drivers;
2. Search takes a large number of time;
3. The system is extremely unstable;

Thanks to such assistants, the search process will be reduced to a minimum and will not require unnecessary actions from you.

Conclusion

Most users experience connection errors. For some, this problem occurs once, while others suffer from permanent basis due to incompatibility with the device and lack of update. I hope that with the help of this article you will be able to solve the problem of why the Internet on your laptop disappeared via Wi-Fi.

Video instruction

If you still haven't found a solution to your problem, perhaps this video will be useful to you.

The most popular problem among Internet connections and Wi-Fi networks is when the laptop does not connect to Wi-Fi networks, through the router. We have a lot of questions on our website on this very topic, and they often ask what to do if the laptop doesn’t want to connect to the Internet via Wi-Fi? I decided to write a separate article in which to collect everything possible reasons and their solutions related to connecting to Wi-Fi networks.

We will look at laptops and computers with Wi-Fi adapter ami. Simply put, any computer that can connect to the Internet wirelessly. Also, this article is suitable for Windows 7, Windows 8, and Windows 10. We already have many separate instructions on our website, with different solutions, specific problems with Wi-Fi on both Windows 7 and Windows 10 laptops. As I write this article, I will provide links that you will definitely find useful.

In the very question “what to do if the laptop does not connect to Wi-Fi”, there is no specific information. There can be many reasons why you cannot connect your computer to the router, as well as solutions. And as practice shows, the computer is not always to blame. I'll try to look at everything in order possible problems so that you can fix them yourself without any problems. Of course, everyone different laptops, different routers, settings, problems, errors, etc. This undoubtedly complicates the task, prepare universal instructions, which would help absolutely everyone in a very difficult way.

If you have a laptop with installed Windows, There is Wi-Fi router, which is distributed by the network, and you just can’t connect your laptop to the Internet via a wireless network, you can’t figure out what’s what, then this article should help you.

Before we move on to any settings, be sure to try connecting your laptop to a Wi-Fi network using. If you have Windows 10, then see. Perhaps you will succeed. If the problem remains, Wi-Fi computer connection failed, then see the article further.

I would divide all problems with Internet connection and operation into three categories:

• The laptop does not see the Wi-Fi network at all: wireless adapter turned off, driver not installed.
• The computer sees the Wi-Fi network, but does not connect to it: the password is incorrect, “failed to connect,” endless connection etc.
• The laptop connects to the wireless network, but the Internet does not work: “No Internet access”, “Limited”.

You can go straight to the section you need, depending on what problem you have. Whatever it is, it must definitely fall into one of the categories. It will be much simpler and clearer this way.

What to do if the laptop does not see the Wi-Fi network?

And so, let's start with the problem when your computer does not see wireless networks at all. At the same time, you are absolutely sure that your Wi-Fi network is working, there is neighboring networks, and they appear on other devices. But they are not in the list of available networks in Windows. And there is no list itself. In this case, the connection status (icon on the taskbar), most likely it will look like this:

If in the notification panel you see a wireless network icon with a red cross "no" available connections", then most likely there really is not a single wireless network within the radius. But it is possible that this problem appeared for other reasons. In this case, running "Problem Diagnostics" may help. (you can start by right-clicking on the connection icon). Wrote about this on Windows example 10, in the article.

Most likely, you have the first case. Red cross near the computer. In this case, the driver for the Wi-Fi adapter is not installed. Or, the wireless adapter itself is turned off. Let's first make sure that everything is in order with the driver, since without it nothing will definitely work.

Checking the wireless adapter driver

To do this, we need to go to the device manager. Right-click on “Computer” or “This PC” and select Properties. In a new window, on the left, open device Manager. You can also go to the start menu and start writing “device manager” in the search and open it in the search results.

In Device Manager we need to open the tab Network adapters , and see if there is a driver for our wireless adapter there. You will recognize it by these words in the name: “Wireless” and “Wi-Fi”. This is roughly what it looks like:

If everything is in order there, then read this article further. If the driver for the Wi-Fi adapter is not in the device manager, then you need to install it, and everything will work. If you don’t know how to install the driver, where to download it, etc., then see the article on. On Windows 8 or Windows 10, this process will be virtually no different.

The main thing is to download and install the driver specifically for your laptop model (or the adapter itself if you have a USB/PCI adapter), and for yours operating system. Well, I recommend downloading the driver from the official websites of the manufacturers. If it doesn’t work out at all, then you can try programs for automatic installation drivers. But that's if you can't find it required driver and install manually.

Checking if the wireless adapter is turned on

The adapter itself, through which the laptop connects to Wi-Fi, or rather in our case does not connect, can be turned off. This needs to be checked. Right-click on the Internet connection icon and select "Network and Sharing Center". In the new window, select Change adapter settings.

There must be a wireless adapter network connection, or Wireless network - in Windows 10. If such an adapter is not there at all, then see above where I wrote about installing the driver. If it is, then perhaps it is turned off. Right click on it and select Turn on.

If it is enabled, then you need to check whether the wireless connections on the laptop itself are disabled. On every laptop, there is a keyboard shortcut that can be used to turn off/on wireless connections (activate airplane mode), including Wi-Fi. This, as I already wrote, is either a key combination or some kind of separate switch. For example, on Asus laptops, these are the Fn+F2 keys. You can always find this combination yourself. Key Fn+antenna key, Or something like that. You can view separate instructions By . And if you have Windows 10, then see these instructions

So we’ve sorted out the problems that prevent us from connecting to Wi-Fi. When the list of networks available for connection is not displayed. If you've tried everything, but you can't get your computer to see wireless networks, then it is possible that the adapter itself (hardware) is simply broken or disabled. This, by the way, often happens after disassembling a laptop and cleaning it from dust. You can describe your problem in detail in the comments, I will try to advise something.

Computer won't connect to Wi-Fi

According to plan, second a big problem this is when the laptop sees and displays a list of available networks, your network is there, but it does not connect to it. At the same time, other devices connect to your network (it would be good to check and make sure of this). Let's now look at the most popular problems with connecting to Wi-Fi in Windows 7 and Windows 10. On the eight, everything is the same, there is nothing new there.

First of all, if any error appears, reboot your router and computer. Try connecting again.

Error: "Windows could not connect to..." and "Cannot connect to this network"

A very popular error that may appear when trying to connect a laptop to a Wi-Fi router.

I wrote about solving this error in Windows 10. As for Windows 7, the solutions are the same. To be honest, there are not many solutions there, the error is not very clear, and there is no specific way to get rid of it.

What else can you try to do: check on the laptop, in properties Wireless network connection (protocol version TCP/IPv4) Is it set to automatically obtain an IP address? In the router settings, you can try changing the security type of your network to WPA2-PSK (if you have another one installed). All this can be done in the router settings. We have it on our website detailed instructions to change the password on different routers.

There is a solution to the error “Windows could not connect to...” in Windows 7.

Security key mismatch. Windows does not accept Wi-Fi network password

You select your network from the list, specify the password, and Windows writes that the password is incorrect. Well, of course, the computer does not connect to Wi-Fi.

Try again, maybe you really entered the wrong security key. Check if CapsLock is enabled. If the laptop does not want to accept your password, then there are two options: remember the password by looking at it in the router settings, or change the password for your wireless network. See article: . You can change the password, for example, to some simple number. To check, then set a more complex password.

Read more about this error and its solution.

Another error that often appears in Windows when trying to connect to a wireless network. And it usually appears after changing some settings on the router. Basically, this is the network name and password.

When the error “The network settings saved on this computer do not meet the requirements of this network” appears, deleting the Wi-Fi network on the computer always helps, and reconnection. I gave links to instructions for deleting a network in Windows 7 and Windows 10 (forget the network) a little higher (they are highlighted in blue).

After deleting information about the wireless network, simply reconnect, indicating the key to your network.

There is a Wi-Fi connection, but the Internet does not work

This is a completely different story :)

Therefore, we have separate, large articles on this problem, when a laptop connects to Wi-Fi, but the Internet does not work:

I won’t write here why the “No Internet access” and “Restricted” errors appear. The article was already very large. If, after connecting to a wireless network, you encounter a problem when there is a connection, but the Internet does not work, then feel free to follow the links above. I am sure you will find a solution to these problems there.

I wanted to collect all the possible, or at least the most popular, problems encountered when connecting a computer to Wi-Fi. I think I succeeded. If you still could not solve your problem, then carefully read the article again. If it still doesn’t work out, then describe your case in the comments, and we’ll think about it together.

⭐️⭐️⭐️⭐️⭐️ In this article I will analyze the situation when there is no Internet via WiiFi on Android. Those. The network connection itself is there, the Wi-Fi icon is active, but it’s impossible to access the Internet and instant messengers (Telegram, Viber, Skype) and other applications (Instagram, VKontakte, etc.) do not connect.

In most cases, rebooting the smartphone or router that distributes the wireless network helps. Another reason could be software error in work Android and incorrect setting router.

This article is suitable for all brands that produce phones on Android 9/8/7/6: Samsung, HTC, Lenovo, LG, Sony, ZTE, Huawei, Meizu, Fly, Alcatel, Xiaomi, Nokia and others. We are not responsible for your actions.

I'll notice! If you are using public network WiFi or private corporate, then there is a high probability that they will block some social networks and messengers. This is often practiced and you will have to come to terms with the situation.

Checking Internet access

Before using your smartphone or router, make sure that everything is ok with the Internet. What could be wrong with it:

• You didn't pay, so your provider suspended your Internet access. Make sure there is network access through the wire.
• In the router settings there are restrictions on visiting certain sites or a traffic limit (common practice for open networks V in public places).
• There were problems on the provider's side.

After eliminating these factors, proceed to diagnostics, allowing you to understand in the operation of which device the cause of the problem is hidden.

The easiest way is to connect to the wireless network from another phone/tablet/laptop. If another device connects to the network, then the problem is in the phone, which cannot establish a correct connection.

Android glitches

Reboot mobile device. If the cause of the problem was minor system failure, restarting the system will fix it.

After restarting, if the error persists, forget the network and then reconnect to it.

Forgetting the network and reconnecting helps resolve the inconsistency Wi-Fi settings on your phone and router.

If deleting the network does not help, check the proxy server status on Android. It should be turned off:

1. Go to the “Wi-Fi” section of the settings and select the network to connect to.
2. Check the "Advanced" option.
3. Make sure the Proxy Server field is set to No.

Another reason why the phone does not connect to the Internet may be wrong date. To check and change it:

1. Open settings.
2. Select the "Date and Time" section.
3. Set the time and date manually or check the “Network date and time” and “Network time zone” checkboxes.

After installation correct date connect to Wi-Fi. If the wireless network actually works, you will be able to access the Internet.

Checking and setting up the router

If, as a result of some kind of diagnostics, you find out that they occur on all devices that connect to the same wireless network, then look for the cause of the error in the router settings.

Why doesn't my phone connect to Wi-Fi, although it recognizes the network? There are several types of this error:

• There is an endless and unsuccessful attempt to obtain the router’s IP address;
• The smartphone cannot connect to the network, but the access point remains;
• The phone does not find the network at all wifi;
• The connection occurred, but there is no connection to the Internet.

Let's look at all the ways to solve problems with the router. All types of errors can be resolved using the instructions below. Follow all instructions in order to resolve the error as quickly as possible.

Performance check and problem analysis

In more than 60% of cases, the user cannot connect to wifi due to short-term network failures. Before you learn how to connect your device to your router to troubleshoot a problem, complete all of the following steps:

• Reboot smartphone governed by OS Android and your router. The wifi itself must be kept unplugged from the socket for several minutes;
• After rebooting your Android device, go to wifi settings and delete the previously saved access point;

• Now search again (the phone should be as close to the router as possible during the search).

If you are unable to establish a connection using this method, proceed to the next instructions.

It is also necessary to check the password, since most users may simply enter it incorrectly. Because of this, the connection does not occur and it says “Saved”. To check the entered password, go to Wi-Fi settings. Then go to option view mode desired point access. In the password (or keyword) field, click on the “Show password” checkbox and make sure that it matches the one keyword, which is specified in the router settings.

How to view the password in the router settings? To do this, enter the configuration settings window and go to the “Wireless Security” tab. The password is the value in the PSK Password field. You can also change this value. After changing the password, save the settings and try logging in from your phone again.

Changing the access point name

If all your devices, except those running Android OS, connect to the router, you need to rename the access point. Some Android smartphones and tablets have one common bug - they are unable to recognize a network if its name is in Cyrillic or if the network name contains special characters.

Follow the instructions to change the name:

• Go to the router settings;
• Go to the main tab and in the SSD Name field, change the name of the access point. Remember, it should not contain additional characters and letters in Cyrillic. Use only Latin alphabet and numbers;
• Save the settings and try to detect the network again.

Changing the Beacon interval option value

Almost everything modern models routers have a number of advanced connection features. You can fix the network connection problem by changing the Beacon interval parameter. Why is this interval needed? Its main purpose is to set the period of time after which telephone will try to receive from the router special package, which contains information about the operation of the network.

As a rule, on all routers this value is equal to one second (or 100 ms). You can change this parameter yourself to 45 or 70. For most Android smartphones, this value is suitable.

Follow the instructions:

1. Go to your router's settings;
2. Go to the "Advanced Settings" tab wireless connection" Another name is "Advanced Wireless";
3. In the Bacon Period field, enter the required value and save the settings;
4. Reboot your router;
5. Try connecting to the Internet.

Selecting a connection mode

The cause of the problem may be incompatibility of the communication standard of your smartphone and router. To do this, you need to change the connection mode in the router settings.

Follow the instructions:

• Go to your router's settings and enable the advanced wireless network settings tab;
• Find the Mode field and change its value one by one. After each change in the standard, save the settings and try connecting to the Internet from your smartphone.

Channel changes in router settings

If your Internet connection suddenly goes down (you haven't done any access point setup before), it's possible that the previously used link is no longer suitable for your network and needs to be replaced.

To do this, follow the instructions below:

Notice! This method This solution is only suitable if absolutely all devices are connected to the router, but there is no Internet connection.

• Go to your router settings via your computer using any browser;
• Find the tab with wireless network settings;
• Then in the “Channel” tab, change the value from “Auto” to any other. Save the settings and reboot the router. Now connect to the Internet again. If necessary, try connecting to a different channel.

Using third-party utilities to reorganize the connection

Using some utilities, you can find out how to connect your phone to the router without errors. Also similar applications help resolve the error by scanning the entire system of the smartphone or tablet. Let's look at a few useful programs:

• WiFi Fixer – free utility to diagnose and quickly resolve problems related to connecting to your router. You can download and install the program on your device from official page in the Google store https://play.google.com/store/apps/details?id=org.wahtod.wififixer.
