Why there is Internet, but the router does not distribute the Internet via Wi-Fi: reasons. The router works, but does not distribute Wi-Fi: what to do? What to do when WiFi doesn't work

Tune Wi-Fi router not so difficult, however, after this, despite the fact that in general everything works, a wide variety of problems are possible and the most common of them include loss of Wi-Fi signal, as well as low speed Internet (which is especially noticeable when downloading files) via Wi-Fi. Let's see how to fix this.

I will warn you in advance that this instruction and solution do not apply to situations where, for example, when downloading from a torrent, the Wi-Fi router simply freezes and does not respond to anything until it is rebooted. See also - all articles (solving problems, setting up different models for popular providers, more than 50 instructions)

One of the most common reasons why a Wi-Fi connection drops

First, what exactly does it look like and specific symptoms by which you can determine that the Wi-Fi connection disappears for this very reason:

A phone, tablet or laptop sometimes connects to Wi-Fi and sometimes doesn't, with almost no logic.
The speed over Wi-Fi, even when downloading from local resources, is too low.
The Wi-Fi connection disappears in one place, not far from the wireless router; there are no serious obstacles.

Perhaps I described the most common symptoms. So, the most common reason for their appearance is that your wireless network uses the same channel that is used by other points Wi-Fi access next door. As a result of this, due to interference and “clogging” of the channel, such things appear. The solution is quite obvious: change the channel, because in most cases, users leave the Auto value, which is set in the default router settings.

Of course, you can try these steps at random, trying different channels until you find the most stable one. But you can approach the matter more wisely - determine in advance the most free channels.

How to find an open Wi-Fi channel

If you have an Android phone or tablet, I recommend using different instructions:

First of all, download to your computer free program inSSIDer from the official website http://www.metageek.net/products/inssider/. ( UPD: The program has become paid. But they have free version for Android). This utility will allow you to easily scan all wireless networks in your environment and graphically display information about the distribution of these networks by channels. (See picture below).

Signals from two wireless networks overlap

Let's figure out what is shown on this graph. My access point, the site uses channels 13 and 9 (not all routers can use two channels at once for data transmission). Note that you can see that another wireless network is using the same channels. Accordingly, we can assume that problems with Wi-Fi communication are caused by this factor. But channels 4, 5 and 6, as you can see, are free.

Let's try changing the channel. The general idea is to choose the channel that is as far away from any other sufficiently strong wireless signals as possible. To do this, go to the router settings and go to settings wireless wifi networks() and specify the required channel. After that, apply the changes.

As you can see, the picture has changed to better side. Now, with a high degree of probability, the loss of Wi-Fi speed will not be so significant, and incomprehensible connection breaks will not be so frequent.

It is worth noting that each channel wireless network is separated from the other by 5 MHz, while the channel width can be 20 or 40 MHz. Thus, when choosing, for example, channel 5, the neighboring ones - 2, 3, 6 and 7 - will also be affected.

Just in case: this is not the only reason why the speed through the router may be low or interrupted WiFi connection, although one of the most common. This can also be caused by unstable firmware, problems with the router itself or the receiver device, as well as problems with the power supply (voltage jumps, etc.).

Wi-Fi technology is very widely used in life modern man, because it allows you to easily and quickly solve problems with 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 wireless adapter on your laptop is enabled. 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 the standard combination for a particular model:
Fn+F3 for Acer;
Fn+F2 for Asus, Dell or Gigabyte;
Fn+F5 on Fujitsu devices;
Fn+F12 on HP laptops.

After pressing the 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 the operating system the laptop is running.

To programmatically enable WiFi that has stopped working on Windows 7, 8 or 10, you need to perform the following sequence of 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” shared access"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 Network Connection” icon. If your WiFi does not work and the wireless adapter is disabled, the connection icon will not be highlighted. In this case, right-click on its icon and select “Enable” from the context menu that opens. 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 whether the driver is installed, 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 window with the properties of the wireless device, go to the “Driver” tab and pay attention to the items “Date of development” and “Vendor”.

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 depends on some external factors which may weaken it. Ceilings, walls, floors and similar obstacles significantly degrade the signal quality of the access point and laptop.

As you know, the signal quality on a personal computer is displayed in the form of several marks - the more of them, 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 your computer and your wireless router. Please note that after a reboot, the router turns on for up to 5-10 minutes before it starts distributing the network. Be patient. Also, despite the opinion of many skeptics, sometimes the problem diagnostic function found in the Windows operating system helps solve problems with a wireless network.

Thus, most of the existing solutions to problems related to the fact that Wi-Fi has stopped working on a laptop have been listed above. 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 has not started working, there is only one way out - go for help to a quality service center, where they can solve any problems with your 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.

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 are 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, you must take into account that it may not support the modern Wi-Fi mode - 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 the possible problems of not being able to connect to Wi-Fi is a duplicate Wi-Fi network name (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 - the Network Connections window will appear on the monitor. Next, you need to double-click on the wireless connection. 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 test it in the future less problems With the router, 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.

For users wireless internet From time to time you have to face problems associated with the inability to use the Internet. There may be several reasons why Wi-Fi does not work on the phone: from trivial errors with entering a password to more global ones - incorrect router settings.

You can also often hear complaints from users that the speed of wireless Internet leaves much to be desired. How to deal with each of these situations and fully use the Internet from your gadget? In this article we will talk in detail about why the phone does not work via Wi-Fi and how to fix it possible problems on one's own.

Incorrect connection information provided

One of the most common situations related to the inability to use the Internet is an incorrectly entered password in the gadget settings. In modern mobile devices- tablet PCs and smartphones - there is a wonderful function - saving a password. This will help avoid mistakes when entering complex password combinations.

However, such a measure will not be effective if the password for the access point is changed in the router settings. Why did Wi-Fi stop working on my phone if the connection was correct before and the password was saved in the smartphone settings? Most likely, the problem is that the administrator changed the password and did not warn the user about it.

Viruses have entered the operating system of the gadget

Another answer to the question why Wi-Fi does not work on the phone may be the presence of a virus program. People who use gadgets on the Android platform most often have to deal with this problem. It is for such devices that a large number of malware have been created. Specialized “cleaning” programs can help you cope with the virus; you can download them through the Play Market service.

We also draw the attention of users that in order not to encounter a similar problem and not be tormented by the question of why Wi-Fi on the phone does not work well or does not work at all, you should install applications only through the standard market of the operating system.

Error in date and time settings

Incorrect values in the calendar and on the gadget's watch face also cause the wireless access point to become unavailable. A similar situation occurs for personal computers. All the user needs to do is adjust the data. After this, Internet access will be provided as normal.

Router settings

Many of the users who have a router installed do not even suspect that this equipment has quite a lot of different settings, limited to entering the name of the network and setting the degree of protection.

However, they often have to wonder why Wi-Fi does not work on their phone. In such a situation, the access point will be present in the list, but when you try to connect to it, a notification will be issued. How to fix this?

First of all, you need to go to the router settings menu - for each device model there is a personal combination of characters that must be entered into the browser in order to access it. It is recommended to check the user manual for information regarding your specific model. After the router menu opens on the computer display, you need to check the following parameters in the " Wireless Internet settings":

Channel - auto.
Mode - 11 bgnMixed.
MAC Address Filter - disabled.

After correcting the data, if necessary, you should save the setting and restart the device.

Problems with the gadget software

The answer to the question "Why doesn't Wi-Fi work on my phone?" may also be due to the fact that there are some difficulties in software gadget. Similar failures can occur when tampering with operating system, for example, non-original firmware is installed.

In this case, it makes sense to use the built-in function to return your smartphone or tablet to factory settings. This opportunity is available for all modern models. It is worth considering that a number of data will be deleted from the gadget - applications and files. Therefore, it is recommended to first save important information to third-party storage media.

To conduct a test and check whether the problem is really in the software, it is recommended to try connecting to several wireless Internet points.

Reasons for low wireless Internet speed

Why is Wi-Fi on my phone slow? There can also be several reasons for low speed, here are the most common:

Many people use the Internet at the same time. The load on the network causes the speed to drop, and in some situations the signal may periodically disappear altogether.
There is a hardware level limitation. This can be applied in public places to normalize the load on the network.
Low data link speed. If the speed of the Internet, which is distributed through a router, is low, then via Wi-Fi, accordingly, you will not be able to fully use the Internet.
