Today we will try to analyze a pressing issue - the loss of a 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.

Why can't I connect to the Internet via Wi-Fi?

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

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

Different devices display fault statuses differently. On a laptop, an exclamation mark may appear in the Wi-Fi network status bar, indicating a connection problem.

On Android devices, the Wi-Fi icon changes 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 Windows OS, the connection is a little easier:

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

Sometimes there is a situation in which the Wi-Fi icon is missing. 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 click on it right click mice.

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 the 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 absolutely refuses to work, try connecting to another network. For example, with friends, or distribute a connection with 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 “Changing 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. new version firmware. You can call the manufacturer's technical support. They will be happy to help you update your gadget.

If the update does not help, then you should contact the 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 set the correct compatibility algorithm for various devices. There may be no connection on the PC, but the mobile phone will 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 computer adapter drivers can create many connection problems. You can update drivers in several ways:

Using a helper program. Driver Pack Online is a 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:

Limited number of drivers;
The search takes a lot of time;
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 on an ongoing basis due to incompatibility with the device and lack of updates. 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 instructions

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

Wi-Fi technology is very widely used in the life of a modern person, as it allows you to easily and quickly solve the problem of connecting to the Internet without using conventional wires. This is especially true when using laptops, which can be used to access the Internet in any convenient place thanks to the presence of a built-in Wi-Fi adapter.

That is why the situation when Wi-Fi does not work on a laptop leads to significant inconvenience and even some problems. There are many reasons why Wi-Fi may not work on a laptop computer. It is simply unrealistic to solve the most serious of them on your own without the help of specialists, but there are quite a lot of them that can be eliminated on your own. Let's look at them.

Is the problem with your laptop or router?

A fairly common problem that a laptop has stopped connecting to the WiFi network is not a problem with the laptop itself, but with the settings of the router that 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 rule out 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, etc.

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

Hardware enable adapter

Based on such diagnostics, you can accurately determine that this problem arose precisely because 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 adapter is turned on wireless connection on a laptop. Almost all modern models have light indicators for the operation of the WiFi module and there are special key combinations to enable it in hardware.

Typically, a lit indicator indicates that the module is turned on. If the indicator does not light up at all or lights up in red, then Wi-Fi is not working precisely because of the wireless network adapter. It must 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 body or near the touchpad.

To enable the module of such a network, press the key combination Fn and one of the system keys F1-F12. The specific 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 Wi-Fi you should try pressing 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 corresponding keys, we check whether the wireless connection module operation indicator lights up or whether it stops glowing red. After this, you should try to connect to the network again. If this does not help, move on to the next step.

Software enablement

When Wi-Fi stops working and turning it on in hardware does not give positive results, you also need to turn it on in software, which is done directly from operating system, under which the laptop runs.

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

1. On the notification panel, which is located near the clock, select the network connection status icon;

2. From the list that opens, select “Network and Sharing Center” or “Network Settings” depending on the version of the operating system;

3. The next step is “Changing adapter parameters.”

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

In this case, the wireless network adapter turns on, all you have to do is find the one you need in the list of available wireless networks and connect to it.

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

Driver installation and update

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

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 device manufacturer should be indicated: Realtek, Atheros, Qualcomm or something else.

Having found the desired item and right-clicking on it, select “Properties” from the context menu. In the window that opens, there should be an item “Device is working normally.” But even if there is a mark indicating the normal operation of the device, this is far from a guarantee that the correct driver version 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 “Development date” and “Supplier” items.

If the supplier is Microsoft or the program development date 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 there is no wireless adapter among the list of installed devices.

If the wireless communication module is present in the list of devices, but is 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, opening the device properties window, you need to click the “Engage” button.

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

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

External obstacles to the signal

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

As is known, the signal quality is personal computer is displayed in the form of several marks - the more there are, the higher the quality of the signal. If the wireless connection level is displayed as 1 or 2 marks, then you don’t have to try to use WiFi - in this case it will not work properly.

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, but often effective solution: restart both the computer and 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 problem diagnostic function found in the Windows operating system helps solve problems with a wireless network.

Thus, most of the above have been listed existing solutions problems related to the fact that Wi-Fi stopped working on the laptop. Almost all such methods and recommendations can be used by anyone who is faced with a similar problem, since this does not require any special skills.
If nothing helps, and the wireless network does not start working, there is only one option left - go for help to a quality service center, where they can solve any problems with the laptop.

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

There are many reasons why your phone won't connect to wifi. Mobile phones are able to provide us with access to the Internet, no matter where we are.

However, sometimes it turns out that the phone has stopped connecting to a non-wifi network.

In most cases, the smartphone tells us what the problem is by displaying characteristic notifications on the screen.

Sometimes, when the connection indicator shows that the phone is connected to Wi-Fi, you still cannot access the Internet and pages do not load.

In this case, it makes sense to look for the “ ” notification in the network settings, which often appears in such cases.

In this case, you can try to solve the problem in two ways. Often this problem occurs due to the fault of the router.

Most likely, no matter what device you tried to connect to this network from at that moment, from a laptop or tablet, the result would be the same.

The simplest solution is to try turning the router off and on again. Let it cool down for about 10 minutes and try to connect again. It is likely that the problem will be fixed.
In addition, this notification may appear if Internet access is not paid for at home. This problem is also completely solvable.
If the Internet is paid for, the wifi router has been turned off and on again, but you still cannot access the Internet, then the problem is most likely on the operator’s side, and therefore you should call customer support.
Sometimes you will have to do the same if you cannot access the Internet only from your phone, although you can do this from other devices.

Important! Regardless of what connection problem and what method you solve, after taking action, you need to turn off the connection on the device. Then turn it on again to check its functionality.

Obtaining an IP address...

Another common problem arises during the process of connecting your phone to a wifi router. The connection process stops when the phone attempts to obtain an IP address.

The notification “Obtaining an IP address...” may remain next to the network name for hours. Naturally, you cannot go online, since your phone is not connected to it.

The problem is not solved as easily as the previous one. However, the first step is the same - turn off and turn on the router again after 10 minutes. If you still cannot connect after this, proceed to the second step.
Not the most convenient way is to register a static IP address on the device. You actually specify the parameters of the network to which you connect at home.
However, when using this method, problems will arise with accessing the Internet through other networks. In order to do this, you will have to erase the IP address and change its type.

You can register a static address as follows:

When you click on the title wifi networks, in the window that opens, an item called “Advanced settings” will appear, “ Additional options"or similar;
Check the box next to this item;
After that, in the “IP Options” or “IP Settings” section, change the type network protocol(DHCP) to static and register the IP.

Before you try to connect to the Internet through another network, change the protocol type again from static to automatic.

Authentication Error

A common reason why you cannot connect to the Internet.

This notification that your phone displays after trying to connect to your home's wifi network actually means that the network has not recognized your device as suitable for wifi reception.

The most common reason why this happens is an incorrect network password. Check it carefully and try to go online again. If you are sure that the password is correct, proceed to the next step.

This is already familiar advice. Try turning your router off and on again after a few minutes. This is a universal recommendation that is given even by customer support operators.
More the hard way– try making changes to the router settings. To do this, you need to go to its settings page through a browser.

Select the following data in the router settings. Version WPA-PSK, encryption – AES. Enter the password.

On most routers these should only be numbers, no more than 8 pieces. Set the security mode to WPA\WPA 2 personal.

These options make connecting to wifi as easy as possible. However, such actions are necessary only when nothing else has helped.

And, in addition, there is reason to believe that there are compatibility problems, for example, with the type of encryption used by the router and phone.

Saved, WPA\WPA2 protection

This problem is one of the most common reasons why the phone does not connect to wifi. You should start with a traditional router reboot. However, in this case it rarely helps.

You need to make changes to the router settings. To do this, open the settings page in any browser.

Make sure the region you set is correct or change it if necessary. If the problem is with encryption, then you need to repeat the same steps as if there was an authentication error.

Set the parameters that will make the process of connecting to the network as easy as possible.

Some problems with connecting to wifi can be resolved by simply deleting the old connection and finding this network on a new one.

In addition, you can try restarting the phone, since connection problems are often caused by a minor glitch in the device’s internal settings.

This is especially true if the phone suddenly stops connecting.

Often the 3G network interferes with the connection to the router.

All steps described in this article should only be performed if you are an experienced user.

Otherwise, it is better to contact the operator’s customer service for help, since your mistake can cause more serious problems in the system.

HOW TO CONNECT ANDROID TO WIFI / WHY DOESN’T YOUR PHONE CONNECT TO THE NETWORK?

Main problems: Why the phone does not connect to WiFi

Before you begin to find out why Wi-Fi or the Internet does not work, you should know (especially for those who have just purchased a Wi-Fi router) that it is not enough to just connect the provider’s cable to the router, you also need to configure it (set up the Internet and Wi-Fi network ). All of the methods described below are valid if Wi-Fi and the Internet were working for you before, and then suddenly stopped or you cannot connect a new device to Wi-Fi. For convenience, I divided the article into two parts, the first is devoted to the inability to connect to a wireless network, the second part will answer your questions if you have connected to a Wi-Fi network but there is no Internet.

Cannot connect to Wi-Fi network.

Reboot the router.

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

Enabling the Wi-Fi module on the laptop.

Check if Wi-Fi is turned on on your laptop, I won’t bother, I described all the ways to turn on Wi-Fi in the article How to turn on Wi-Fi on a laptop .

Change the wireless network mode.

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

Removing a duplicate network SSID.

One of possible problems Inability to connect to Wi-Fi is a duplication of the Wi-Fi network (SSID). Suppose you come to your friends, their Wi-Fi network is called “Home”, you successfully connected to it. Time passed and you came across the same network name with other friends or at home. The laptop (this also applies to tablets and smartphones) tries to connect to the network using the previously saved password, but it fails because a new password is used for this name. To solve this problem, you need to remove from the list of saved Wi-Fi networks matching network.

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

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

No Internet via Wi-Fi.

Internet payment check.

The simplest thing that can happen when the Internet is not working is that it’s time to pay for it or the provider is working on it. To clarify the situation, call your provider and find out if you have a debt for the Internet and whether work is being done on the line.

Static IP address.

One of the problems with the Internet not working may be that the registered static address does not have the network settings that are necessary. In this case, I recommend using automatic network settings retrieval. To do this, you need to go to the Network and Sharing Center. One way to do this is to right-click on network icon in the lower right corner of the screen and select "Network and Sharing Center".

Another way is to use hotkeys + , enter the command ncpa.cpl and press Enter.

It doesn’t matter which method you used, the result will be the same - a window will appear on the monitor Network connections. Next you need to wireless connection press with two mouse clicks, In the status window that opens, select "Properties" in the properties window "Internet Protocol version 4 (TCP/IPv4)"

Problem with the router.

The Internet may not work due to a router failure; the simplest thing you can do is reboot it. There are situations when the router resets the Internet settings, in which case you need to connect to it via the web interface and re-enter the Internet settings, in order to experience fewer problems with the router in the future, I recommend updating its firmware.

Conclusion

In this article, I described all the ways I know to solve problems with Wi-Fi and the Internet. If these methods do not help you, you can describe the problem in detail in the comments and I, together with the readers of this site, will try to help you.
