WiFi is wireless technology new generation. Just a little time, and this method of connecting to the Internet is used by millions of users around the world. Wi-Fi communication makes it possible to connect compatible devices located at a distance of up to fifty meters from the access point. The data exchange rate is about 150 mb/s. However, that's not all. Thanks to recent advances in this area, speeds can reach several gigabits.

Every modern laptop, tablet or phone has a Wi-Fi radio module. This results in significant savings in expensive operator traffic. mobile communications, and the radio module also provides access to high-quality multimedia content, without the need to download anything to the device. All you need to do is set up a Wi-Fi connection on your portable device, ask security password and then save it so that broad access to the Internet opens. However, sometimes not everything goes as smoothly as it seems.

Sometimes Wi-Fi doesn't connect. Why? There are a number of reasons for this, the main ones of which we will now discuss.

Why do problems arise?

Mostly failures occur while connecting the device to Wi-Fi networks arise due to incorrect settings wireless router. In this case, the laptop or tablet does not recognize the Internet connection at all. If this happens at home, you need to sequentially perform a series of actions described below:

If a pop-up message appears when you connect your portable device to a Wi-Fi network “Saved, WPA-WPA2 protection”, this means that the encryption on the router is incorrectly configured or the password for the Wi-Fi coverage is entered incorrectly. To fix everything, you need to follow these instructions:

  • Check if the password is entered correctly by opening “Connection” and clicking “Change”. Next, you need to select the password display function and enter it again.
  • If the password is entered correctly, but there is still no access, it means that the router settings are problematic.

If the settings are incorrect, you must:


Bottom line

So now your laptop, tablet or smartphone should be able to connect to Wi-Fi. In this case, the initial connection between the device and the router will be broken, you need to connect again. Regarding encryption issues, in these cases you also need to proceed step by step:

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

These are, perhaps, all the main actions that you can do at this stage. In other cases, it is better to contact specialists for more precise settings.

The phone does not connect to the WiFi access point - this is an error that occurs quite often these days. The fact is that smartphones with a built-in Wi-Fi adapter have already become a part of people’s lives, and almost everyone already has such a device. Smartphones have become so widespread due to their undeniable qualities. After all, they allow you to use the Internet and solve problems no worse than a computer, but at the same time they are mobile and compact.

Unfortunately, although in most cases connecting to a WiFi network occurs without problems by pressing just one button, sometimes various errors still occur that not every user can solve on their own. That is why in this article we will look at why the phone does not connect to the home WiFi network, as well as how to fix this error.

Reasons why your phone does not connect to the WiFi network

In fact, there are many such reasons. Moreover, there may be problems that require an individual approach. This is explained by the fact that the domestic market has a huge amount of wireless equipment that has individual characteristics and unique solutions. Therefore, it is impossible to sort out absolutely all the errors, just as it is impossible to find a universal solution, a panacea.

We will look at the problems that occur most often and also look at how to solve them. Their list includes the following:

  • Incorrectly entered security key.
  • Incorrect Wi-Fi router settings.
  • The router malfunctions (freezes).
  • Failure of the Android platform (rare, but still occurs).

So let's look at all these errors in more detail.

Why the smartphone does not see the Wi-Fi network: Video

Incorrectly entered security password

Very often, the phone does not connect to a wireless home WiFi connection due to an incorrectly entered key. Try entering it again, but this time check the box next to “Display characters” (or “Show password”). Pay close attention to where capital characters are used, and also pay attention to the language in which the key is entered.

At the bottom of the screen, click “Advanced settings”. Now in the window called “WiFi” we find the “Security Settings” section. The first line “Network Authentication” is the type of data encryption. The second line “PSK encryption key” is the password for our network. This is what you need to enter when connecting your phone.

Checking your router settings

An error in connecting your phone to a WiFi wireless network often occurs due to incorrect router settings. The fact is that modern Wi-Fi routers support DHCP technology. This means that all data about the router connection is automatically sent to the phone. This is exactly what smartphones and tablets are aimed at. If you disable this function, the phone will not be able to obtain an IP address and, accordingly, connect to the network.

The solution to the problem is to enable this feature if it is disabled. To do this, you should return to the router settings and open advanced settings. Now we are interested in the window called “Network”. In it we go to the “LAN” section. These are the local network settings.

This is where you can enable or disable DHCP. It is worth noting that to enable the function in the “Mode” line you should set “Allow”. Below is a range of IP addresses, you can also change it. After enabling the DHCP feature, apply the settings and save the changes. It is also recommended to reboot the router. After this, try connecting your phone again.

WiFi router malfunctions

Another reason why the phone sees WiFi network, but does not connect to it, the reason is that the device is simply frozen. In this case, for example, a laptop can work normally and access the Internet. The fact is that when talking about freezing, one should understand failures and stoppages of some functions. For example, due to overload or power failure, DHCP may stop working. In this case, devices that were connected to the access point before have already received an IP address and can work normally. Other functions of the Wi-Fi router may also stop working.

The solution to this problem is to simply reboot the device. And you don’t even need to go into the settings to do this. It is enough to unplug the router's power supply from the outlet for 7-10 minutes. After that, turn it on and wait for it to load. Try connecting again from your phone. Such freezes can occur not only on budget router models. The only difference is the frequency of such errors.

If you have completed all the above steps, but the Wi-Fi network connection error on your phone remains, then it is quite possible that the failure occurred in the smartphone itself. The fact is that mobile devices use regular wireless adapters, which can also freeze or work with errors. But, unlike a computer, there are no advanced settings on the Android platform. On such platforms, all parameters are entered initially, and there is no way to change them. This means that this problem can be solved in the same way as in the previous case - just reboot the device.

For two years he worked as the head of a service center specializing in connecting subscribers to the Internet and computer assistance.

A smartphone without the ability to connect to Wi-Fi is not a smartphone, but just a dialer, because the Internet is via a network mobile operator It is quite expensive, and the quality of such communication often leaves much to be desired. Meanwhile, problems with connecting to Wi-Fi are a very common phenomenon and in most cases easily solvable. Let's talk why mobile phone does not connect to Wi-Fi and how to fix this problem on your own.

How to determine where the problem is

The culprit for a failure to connect to a Wi-Fi network can be either the phone or the distributing access point. Problems with a mobile phone can be suspected in the following cases:

  • The phone only receives a Wi-Fi signal in the immediate vicinity of the router (any router). As soon as you move away, the connection disappears. Other devices connect normally.
  • The phone does not connect to any access point, although it detects them.
  • The list of Wi-Fi networks on the phone is always empty, while other devices see nearby networks.
  • The connection problem arose after some actions with the phone - updating the firmware, installing applications, changing settings, dropping it on the floor, etc.
  • The phone stopped connecting to Wi-Fi after leaving for another region.

And in these situations, the access point is most likely to blame:

  • No device is connected to it.
  • Devices connect, but there is no Internet access.
  • When you try to connect, some messages or windows appear on the phone screen (not for entering a password). Moreover, when establishing a connection only with this network.
  • The connection problem arose after some actions with the router - moving to another location, updating the firmware, changing settings, etc.

There are often ambiguous situations where the culprit may be a smartphone, an access point, or a transmission medium. For example, when the phone is endlessly obtaining an IP address, or when, after a short attempt to connect, the message “Saved” or “Authentication Error” appears next to the network name.

Causes of connection problems

Possible sources of problems with your phone:

  • Incorrect network settings.
  • Blocking the connection by applications or malware.
  • Damage to the network structure operating system.
  • Hardware failure or poor design solution (for example, weak antenna).

Possible reasons for failure on the part of the access point:

  • Tuning to a very noisy broadcast channel.
  • Non-optimally selected transmitter power WiFi signal.
  • Incorrect encryption settings.
  • Disabling the DHCP server (necessary for client devices to obtain IP addresses).
  • Reaching the limit of simultaneous connections (a common occurrence on public networks).
  • Blacklisting a phone's MAC address and using tools parental controls.
  • Software and hardware failure, including due to overheating.

Problems from the transmission medium:

Algorithm of actions for diagnosing and eliminating a failure

Inability to connect the phone to public or corporate network We will not consider Wi-Fi in this article, since the user cannot control its settings. Let's consider situations that arise in the home networks of phone and access point owners.

So, in order. If the action does not help, move on to the next one.

The access point parameters are shown using the example of a TP-Link AC 750 Archer C20 home router. On other routers, the names of sections and functions may differ, but not globally.

  • Check if Wi-Fi is running on your phone. Go to your wireless settings and make sure the switch is set to On. If the feature is active, turn it off and on again. Reboot your phone.

  • Make sure the access point is working and check if other devices are connecting to it. If not, reboot your router. Make sure it is not overheated.
  • Place your mobile phone in an area with good Wi-Fi reception. So that between it and the router there are no thick concrete walls and sources of electromagnetic radiation ( Appliances, power cables).
  • If an authentication error occurs when you try to connect, it is possible that someone in your family or you yourself have changed the password for connecting to home network, and your phone is trying to establish a connection with it using the old password. To forget your mobile device Old Password, open with long touch context menu connections and select “Delete” or “Forget this network”. After this, the network will remain in the list of available ones, but will require you to enter a password the next time you connect.

  • Enter the correct password in the next field.

  • Remove applications from your smartphone that were installed or updated shortly before the problem occurred. Check your device for malware infection. Disable or temporarily uninstall VPN clients, antivirus, and other programs that are supposedly used to protect networks.
  • If the connection is not restored or another error occurs, for example, it takes forever to obtain an IP address, open the “DHCP Server” section in the router’s control panel and make sure that it is enabled. Your phone's IP must fall within the range between the start and end DHCP addresses and not be the same on other devices.

  • If the problem connecting to your home access point occurs not only on your phone, open the basic wireless network settings in the control panel of your router and experiment with switching broadcasts to different channels. If the default channel is very noisy, the connection will either be impossible or extremely unstable.

  • Check what standard your wireless network uses. If your phone old models, and the router is configured to the modern standard 802.11n or 802.11ac, the connection will not occur. To make the new router compatible with older client devices, you must switch it to 802.11bgn (mixed) mode.

  • Inspect your Wi-Fi traffic protection settings. Go to Wireless Security and make sure you select an encryption method that is compatible with your smartphone. The modern and most reliable encryption type is WPA2-PSK; it is supported by all mobile devices released in the last 10 years. If your phone is very old, it may only support WEP mode. In addition, the encryption system sometimes fails. To test this version, temporarily disable protection. If you can connect to the network, use WEP encryption in the future or delete the network and create a new one.

  • Check if the MAC address is included network adapter your smartphone to the list of those for whom connection is prohibited. You will find information about this in the “MAC Address Filtering” section.

  • One of the rare reasons for the inability to connect to an access point is an incorrectly selected Wi-Fi transmitter power level. To check this version, go to " Additional settings wireless network" and change the power level to higher or lower.

What to do if nothing helps

If you are inclined to believe that the culprit of the problem is the phone:

  • Reset the operating system to factory settings.
  • Reflash the device with known correct firmware.
  • Contact service center for repairs mobile devices, since the failure may be due to a hardware fault. It cannot be eliminated at home.

If the main suspect is the router:

  • Provide the device good cooling- Install it in an open place away from heat sources.
  • Reset the device to factory settings and set the values ​​you need again.
  • Update your router firmware to latest version or install an alternative - WRT-DD, if the device supports it.
  • If the device is older than 3-5 years and this is not the first time a failure has occurred, consider replacing it. Unfortunately, modern routers in the mass segment quickly exhaust their service life and rarely serve their owners for a longer period of time.

When buying a new router, don't choose the most budget models, since the bulk of problems with connecting to Wi-Fi occur precisely among them.

Before you start figuring out why Wi-Fi or the Internet does not work, you should know (especially for those who have just purchased Wi-Fi router), that it’s not enough just to connect the provider’s cable to the router; it also needs to be configured (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, please note that it may not support modern mode Wi-Fi work -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 this name is used New Password. To solve this problem, you need to remove the matching network from the list of saved Wi-Fi networks.

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

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 retrieval network settings. 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 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 this 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 specified methods did 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.

So you bought or were given a laptop or computer. The very first thing you will do is connect it to the Wi-Fi network. In the vast majority of cases, everything happens in a matter of moments. But let’s imagine a situation when Windows starts producing various kinds of errors, and the device does not see the connection. What to do? Why doesn't my laptop connect to Wi-Fi and the connection icon is crossed out in red? Not very experienced users begin to give up. But don’t be upset, this problem is completely solvable. Read our guide and you will know how to connect to Wi-Fi.

Not everyone knows how to solve Wi-Fi connection problems

Let's look at the main factors why the Internet does not function and how to solve each of them. If you can't resolve the problem, you've come to the right place.

Turning on Wi-Fi

It often happens that the module wireless communication deactivated. You can activate it in different ways.

Way 1: Using function keys

Absolutely all modern laptops are equipped with an Fn button. Its purpose is to control certain functions of the device together with the F1-F12 buttons. In some models, Fn launches auxiliary functionality, and in others, it returns the built-in Windows functionality to the F1-F12 keys.

Turning Wi-Fi on/off is one of its functions. Look through the F1-F12 keys to find one with an image of an antenna (on Lenovo models, this is a button with an image of an airplane that activates/deactivates airplane mode). Press the button or its combination with Fn. If successful, a network icon with an asterisk will appear in the system tray, representing the available networks. Choose yours and try to connect.

Path 2. Through Network Sharing Center

Try connecting using this method if the first one fails. To get into Windows connection management:

  • Start - Control Panel - Network and Sharing Center - Change adapter settings.
  • Right-click on the Internet icon in the system tray - Network and Sharing Center - Change adapter settings.
  • For Windows 8–10: press Win+X - Network connections.

If the adapter is inactive, its image will be gray. Select it with a single click and in the menu bar just above activate “Enable network device" A connection icon in the form of an antenna with an asterisk should appear in the Windows system tray.

Way 3. Through Device Manager

This method is suitable when you have activated Wi-Fi, but the laptop cannot connect to the network. Go to Device Manager:

  • Start - Control Panel - Device Manager.
  • Win+X - Device Manager.
  • Search in Windows - type "Device Manager".

You will see a list of all available equipment. In the “Network adapters” column, find Wireless adapter. The name may contain the word Wireless. If the user sees an arrow in a circle next to the name, then he must right-click and select “Enable” (“Enable”). Again, the network icon should appear in the tray.

Driver installation

When in the Device Manager there is no name of the chip, but instead, for example, “Wireless network adapter” is displayed, and next to the name there is Exclamation point in the middle of the triangle, you will need to install the driver.

If you have a laptop, all you need to know is the device model. Then go to the manufacturer’s support website, download and install the driver for your operating system. If you have a computer, it is better to know the model of the Wi-Fi adapter; It is possible that you still have the box after purchase. If you don’t know for sure, double-click on it in the Manager, in the “Details” tab, select “Equipment ID” from the drop-down list and search the Internet for the code.

How to install the driver?

  • As a normal program, following the instructions of the installer. You may need to restart your computer. In rare cases, the system does not see the driver installed using this method.
  • Unpack the contents of the archive into local folder. In Device Manager, double-click to open the properties window, in the “Driver” tab, click “Update” - “Search on this computer” - specify the folder with the unpacked archive. The system will install the driver.

Please note that it is best to download drivers for your OS version to avoid incompatibility. An incorrect driver is one of the reasons why the laptop failed to connect to Wi-Fi.

Setting up a network and router

Let’s say that the computer sees the network, the connection is successful, but it won’t let you into the Internet. There is a yellow icon next to the connection icon. Why is this situation happening?

Most often for the reason that the settings of the network chip differ from the settings of the router. Initially, it assigns each device an IP address automatically. Then automatic acquisition of an IP address must be activated in the module settings. How about making sure of this? Go to “Network Connections” (read above how) - “ Wireless network" - "Properties" - "IP version 4" - "Properties" - "Obtain an IP address automatically." When the settings do not match, you cannot access the World Wide Web.

If it still doesn't work

Troubleshooting

The Windows utility will scan your computer for errors in the operating system and network card: Right-click on the connection icon - Diagnose problems. The utility will begin scanning. Follow her instructions.

  • Type of network problems - I have a different problem - Using a specific network adapter - Wireless network.

What when no steps are successful and troubleshooting reveals no errors? The laptop cannot connect to the Internet or does not see the network? In most cases, rebooting the laptop/router will help. It will clear temporary files, RAM devices and, most likely, the computer will be able to connect to the network.

Radical problem solving methods

If you stubbornly cannot connect to Wi-Fi because Windows does not see it, you can reset the router to factory settings. On its back panel there is a small Reset button recessed into the body. Take a pin, press the button and hold it for a few seconds. After this, perform all adjustments from the very beginning.

You need to look for the “Reset” button near all other connectors

Well, if you managed to catch a virus, or system updates were not installed correctly, try Windows recovery.

Conclusion

We brought to your attention possible solutions all situations when the computer does not see the Wi-Fi network. In extreme cases, you may have to buy new equipment, but in most cases, fiddling with the settings is enough to save money.

We'll be glad to know yours personal experience in this question, what did you do when faced with the fact that the computer cannot connect to the Wi-Fi network. We hope that you were able to resolve the issue by following our recommendations. Leave your comments below the article.
