The phone does not connect to home wifi byfly. Why won't my phone connect to my home Wi-Fi? The phone does not connect to Wi-Fi - it requires obtaining an IP address: what to do, how to connect

The problem of connecting to a wireless Wi-Fi network is quite common. Your mobile device may refuse to accept Internet traffic from the router for many reasons. We will analyze the solutions to the most popular problems that happy owners of mobile devices have to face.

Consider solving connection problems using the example of the Android mobile operating system with the MIUI graphical shell and a router from TP-LINK.

Common Wi-Fi Connection Errors

This situation may be accompanied not only by a problem with the software of the phone, but also with the hardware. In this case, the mobile device will need to be handed over to the workshop for diagnostics by experts. We will analyze in order of complexity the problems with connecting to the router from the software side:

Reason 1: Wrong password entered

No matter how ridiculous it may sound, but most cases with a mobile device refusing to connect to a wireless network occur precisely because of an incorrectly entered password. In this case, the user can enter characters in the wrong case (large characters instead of small ones, and vice versa) or miss some of them.

If the router belongs to you, an attacker could change your password through a hack without your knowledge. Find out your password again and try to enter it again with all care.

Reason 2: Router stuck

Even the most expensive device designed to transmit Internet traffic over the air can eventually accumulate "garbage" in the form of extra data packets and temporarily fail. The solution to this problem is very simple - reboot the router. You can do this by turning the router off and on using the power button on the back of the router.

Turn off the router (router) for 10 minutes, then turn it on again. If this banal action did not help, we move on to more complex options for solving the problem.

Reason 3: Mobile Device Authentication Failed

Every day, mobile devices are subjected to a heavy load over the air data transmission medium. This is not only the reception and transmission of Internet traffic, but also mobile calls, SMS messages and everything related to this. Therefore, the device may no longer receive data from the router due to information overload.

1. 1. Remove the network from the Wi-Fi settings on your phone, then reconnect. Then the connection configuration will be redistributed, and, quite possibly, your problem will be solved. We enter the advanced settings of the connected network. When using the MIUI graphical shell, there is an arrow to the right of the network name leading to these settings.

1. 1. Next, click on the button "Delete this network" at the bottom of all settings.

1. 1. After pressing the button "Delete this network" the phone operating system will ask you if you are sure of the action, press "OK".

1. 1. We find our network again and try to connect by entering the password set on the router in a special window.

Reason 4: Connected devices limit exceeded

By default, modern routers are ready to connect 16 or 32 devices to their network. Often this problem occurs with routers in a public place, or those that simply do not have a password set. Of course, the neighbors will not miss the opportunity to use the free Internet, and thus the device that distributes the Internet in your home may be overloaded.

To solve this problem, you need to set a password on your home router to control the number of its clients. If you do not know how to do this, you can read our article on this matter.

When installing protection on a router, try to come up with a password as difficult as possible. A special lesson will help you with this:

In order to find out how many clients are currently connected to your device, you need to go to the router control panel in the tab "Wireless - Wireless Statistics". In the table, the ID value shows the serial number of the device connected to the network:

Instructions for entering the control panel of the TP-LINK router are described in the lesson on changing the password on the router, which was mentioned above.

Reason 5: Hardware failure

No working device guarantees perfect work without breakdowns. Similarly, the router may at one time refuse to continue its correct operation. In this case, it requires hardware diagnostics by an expert in a service center and its further repair.

Problems setting up the router

Connection problems are not ruled out due to incorrect router settings at the moment. All settings are made in the special panel mentioned above when changing the password. It is advisable to change the following parameters only after checking the methods for eliminating common errors.

Do not forget after each change of parameters to save the changes using the "Save" button at the bottom of the settings window. After saving, reboot the router with the button Reboot tab "System Tools - Reboot".

Let's look at additional reasons due to which your connection may be temporarily inoperative.

Reason 1: Duplicate SSID

The SSID is the LAN ID on your router. Simply put, it's his name. If there are two identical models with the same identifiers in the same radio frequency range, disagreements will be created between them. The problem is quite rare, but quite real. To solve this problem, you need to change the SSID of the router to the original one in the tab .

Reason 2: The communication channel is full

In places of accumulation of several routers, which can be a house, office or public place, there are communication channels through which information packets are transmitted. If many routers use the same communication channels, they are overloaded and become unable to transmit more data. What do we have to do?

1. 1. 1. Change the communication channel in the router settings to any other in the tab "Wireless - Wireless Settings" or "Wireless - Wireless Settings" by changing the parameter channel.

1. 1. 1. Change the frequency at which your router transmits data to any other by changing the parameter "Channel Width".

Reason 3: Wrong mode of operation of the router

The parameter in the same settings window called Mode. It is impossible to answer which mode the set parameter needs to be changed due to its subjectivity. Try to solve the problem with the mode change bgn, first trying bgn mixed(combined mode), or, if you own a third-party router, this setting may be called Auto.

Reason 4: DHCP Server Disabled

The DHCP server assigns temporary IP addresses to wireless subscribers. For some reason, this server may be down, which prevents the router from seeing potential devices in its range. To fix this problem, you need to enable the DHCP distribution mode by clicking on the checkmark "Enable" in line DHCP Server tab "DHCP".

Reason 5: Security settings

Sometimes the connection problem lies in the changed data transfer security settings that are provided by the router company. Security settings can be found in the tab "Wireless - Wireless Security". By default, the checkbox is set to "WPA/WPA2 - Personal(Recommended)", and this is the best option for today. It is recommended to set the parameters shown in the screenshot as they are stable:

If they do not suit you, in paragraphs version And "Encryption" you can set options Auto, configuring the parameters in their own way, depending on the behavior of the router on the network. It is undesirable to turn off the parameters at all by clicking the checkmark Disable Security for the security of your valuable data.

Reason 6: The presence of the device in the MAC filter

It's one thing if the filters include dynamic IP addresses of devices that tend to change with a new connection, but the physical addresses are quite another. The owner of an Android phone cannot change this address. The entered physical address of your device in the MAC filter of the router completely blocks its access to the network. Make sure your device is not listed in the table in the tab "Wireless - Wireless MAC Filtering".

As you can see, the problem of connecting to a wireless network is quite versatile, but there is nothing difficult in solving it if you follow the instructions. The graphical interfaces of the control panels of different models of routers may be different, but the essence of the settings is the same everywhere. Depending on the type of firmware, the language accompanying the settings and the graphic component may differ.

Internet problems are always annoying. They can interfere with work or play, or limit other online experiences. If we are talking about connecting via a cable, there may not be so many possible causes of this problem.

The laptop detects an available wi-fi network, but does not connect

One fairly common network problem is when your computer sees a network available for connection, but for one reason or another cannot connect to it. This problem can occur for one of the following reasons:

• a problem with the hardware drivers on the laptop - for this reason, the connection may not be performed or terminated immediately after a successful connection to the network;
• communication interference - too many devices should not be connected to Wi-Fi, and it is also worth making sure that nothing can interfere with your laptop and router;
• the password for connecting to this network was entered incorrectly - if you entered the security key incorrectly, the connection will not be completed;
• network mismatch - if the connection settings on your computer and the network settings do not match, the connection will not be completed;
• failure of the operating system - in case of some problems with the operating system, the connection will not be made correctly.

Solving problems with connecting to a wi-fi network

Let's take a look at the solution to each of the problems mentioned above in turn, and also study general recommendations for those who have encountered this problem in their system.

"Windows could not connect to Wi-Fi" error and how to solve it

When you try to connect, you may see the message "Windows could not connect to the Wi-Fi network." This error can have several causes. You can determine the source of the problem as follows:

Video: Fix Internet Connection Problems

Security key mismatch when connecting to a Wi-Fi network

The security key is the security code for your Wi-Fi network. The user independently sets it so that outsiders cannot connect to the network. And if you encounter an error about entering the wrong password, then it is likely that it was entered incorrectly. Do the following to make sure the situation is corrected:

Do not tell your security key to strangers - this will lead to additional connections, which in turn will slow down your Internet speed.

Stored network settings mismatch

After creating a new connection, you can often see an error with the text "The network settings saved on this computer do not match the requirements of this network." This problem often occurs after self-configuring the router. To correct this situation, all you need to do is delete the connection and then re-create it. This will update all settings and establish a connection again. This is done as follows:

1. Click on the Internet icon in the lower right corner with the right mouse button and select the "Network and Sharing Center" section.

   Select "Network and Sharing Center" in the context menu of network connections

2. After that, you need to open the control menu for wireless networks. This is done using the corresponding button on the left side of the screen.

   Go to the "Wireless Network Management" section

3. Call the context menu of the network that gives an error, and select the "Delete network" item.

   Right click on the connection and click "Delete Network"

4. And then try to connect to the network again. Now that there is no saved data about this network, the connection should work fine if the network is not password protected.

In Windows 10, this problem is solved a little differently:

The problem may arise, for example, due to careless data changes in the connection settings.

Other Ways to Help Connect

And now let's look at a few common solutions that can help you with various connection problems. In our case, when Wi-Fi connection is not possible, these methods will also help.

Rebooting the router

The easiest way, which is advised by all providers in the first place. Of course, this will not help with serious problems, but it can fix one-time connection problems. The best way to reboot is as follows:

Checking and installing network drivers

Updating network drivers is no more difficult than updating drivers for any other hardware. You can do this using the automatic driver download system as follows:

1. Press the key combination Win + X to open the quick access menu and select the “Device Manager” section there. Another way to get to this menu is to right-click on the Start icon.

   Select the "Device Manager" section in the quick access menu

2. In Device Manager, find the "Network adapters" section. Expand this tab and you will see your network devices. And then right click on the available hardware. After the context menu opens, select the action "Update drivers ...". To determine if a device needs a driver update, pay attention to its name and the presence or absence of an icon indicating that drivers need to be updated.

   Open the "Network Adapters" section and click "Update Drivers" on the desired device

3. You will be asked how to upgrade. If there is an Internet connection (for example, using a cable, since a wi-fi connection is not available), then just click on the "Automatically search for updated drivers" button.

   Select "Automatically search for updated drivers" if you have a network connection

4. Wait until the end of the search, download and installation of drivers.

   Wait until the end of the search for drivers on the network and their installation

5. If there is no network access, you must download the driver for your network adapter from another device and select the "Search for drivers on this computer" option.

   To search for drivers yourself, select "Search for drivers on this computer"

6. Specify the location of the folder with the drivers for their further installation.

   Specify the location of the drivers on the computer and click on the "Next" button

7. After the installation is completed in one way or another, restart the computer.
8. Try connecting to the wi-fi network again to see if your problem is resolved.

If a simple update did not help, try completely uninstalling the driver and reinstalling it in the same way.

Reset router settings

If problems with the Internet do not disappear and there is still no connection to wi-fi, it is worth resorting to a more radical way to fix this problem. Namely, reset the router settings and configure it from scratch. You should not do this if you are unsure of your own knowledge and attentiveness - you risk being left without access to the Internet. You can reset your router in the following way:

1. Open any browser and enter the numbers of your local address in its address bar. Try numbers: 192.168.1.1; 192.168.0.1; 192.168.0.254. One of these addresses will be correct.

   Enter the local address of your computer in the browser to open the router settings

2. To log into your account, enter the word admin as both password and login.

   Use the word admin as your username and password

3. Go to the Factory Defaults section and click on the Restore button to completely reset your router.

   Press the Restore button to perform a full reset of the router

4. Another way to reset the settings is to find the RESET button on the back of the device and hold it down for a few seconds.

   

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

How to determine where the problem is

Both the phone and the distributing access point can be the culprits for a Wi-Fi connection failure. Mobile phone problems can be suspected in the following cases:

• The phone receives a Wi-Fi signal only in the immediate vicinity of the router (any). It is necessary to move away - and 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 the nearest networks.
• The connection problem arose after some actions with the phone - updating the firmware, installing applications, changing settings, falling on the floor, etc.
• The phone stopped connecting to Wi-Fi after moving to another region.

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

• No device connects to it.
• Devices connect but no Internet access.
• When you try to connect, some messages or windows appear on the phone screen (not for entering a password). And 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.

Often there are ambiguous situations where the smartphone, the access point, and the transmission medium can be the culprit. For example, when the phone is constantly obtaining an IP address, or when, after a short connection attempt, the message “Saved” or “Authentication error” appears next to the network name.

Reasons for connection problems

Possible sources of problems in the phone:

• Incorrect network settings.
• Blocking the connection by applications or malware.
• Damage to the network structure of the operating system.
• Hardware failure or poor design (e.g. weak antenna).

Possible causes of failure on the part of the access point:

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

Media problems:

• The distance to the access point is too far (weak signal).
• electromagnetic interference.

Algorithm of actions for diagnosing and eliminating a failure

We will not consider the inability to connect the phone to a public or corporate Wi-Fi network within the framework of this article, since the user cannot manage its settings. Consider the situations that arise in the home networks of owners of phones and access points.

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

The access point settings are shown using the TP-Link AC 750 Archer C20 home router as an example. 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 the wireless settings and make sure the switch is set to the "Enabled" position. If the function is active, turn it off and on again. Reboot your phone.

• Make sure the hotspot is working and check if other devices are connecting to it. If not, restart your router. Make sure it's 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 (household appliances, power cables).
• If an authentication error occurs when you try to connect, someone in the family or you yourself may have changed the password for connecting to your home network, and your phone is trying to communicate with it with the old password. To make the mobile device forget the old password, open the connection context menu with a long touch and select "Delete" or "Forget this network". The network after that will remain in the list of available, but the next time you connect, it will require you to enter a password.

• 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, an endless receipt of an IP address, open the "DHCP server" section in the control panel of the router and make sure that it is enabled. Your phone's IP must fall between the DHCP start and end addresses and not be repeated on other devices.

• If the problem of connecting to your home hotspot occurs not only on your phone, open the basic wireless network settings in the router control panel 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 which standard your wireless network uses. If your phone is an old model and the router is set to the modern 802.11n or 802.11ac standard, the connection will not work. For the new router to be compatible with older client devices, you must switch it to 802.11bgn (mixed) mode.

• Inspect your Wi-Fi traffic protection settings. Open the "Wireless Security" section and make sure that the encryption method that is compatible with your smartphone is selected. The WPA2-PSK encryption type is the most modern and most reliable; 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 check this version, temporarily disable protection. If you can connect to the network, use WEP encryption later on, or delete the network and create a new one.

• Check if the MAC address of your smartphone's network adapter is included in the list of those who are not allowed to connect. 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 the wrong power level of the Wi-Fi transmitter. To check this version, go to "Advanced Wireless Network Settings" 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:

• Do a factory reset of your operating system.
• Reflash the device with a known correct firmware.
• Contact a mobile device repair service center, as the failure may be due to a hardware failure. It cannot be removed at home.

If the prime suspect is a router:

• Keep the machine well cooled by installing it in an open area away from heat sources.
• Reset the device to factory settings and set the values ​​you need again.
• Update the router firmware to the latest version or install an alternative - WRT-DD, if the device supports it.
• If the device is older than 3-5 years and the failure occurs not for the first time, consider replacing it. Unfortunately, modern mass-segment routers quickly run out of their resources and rarely serve their owners for a longer period.

When buying a new router, do not give preference to the most budgetary models, since the majority of problems with connecting to Wi-Fi are found among them.

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

In most cases, restarting the smartphone or router that distributes the wireless network helps. Another reason may be a software error in the operation of Android and incorrect router settings.

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.

Note! If you use a public WiFi network or a private corporate one, then there is a high probability that they will block some social networks and instant messengers. This is often practiced and will have to come to terms with the situation.

Checking for internet access

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

• You didn't pay, so the ISP has suspended internet access. Make sure you have access to the network through the wire.
• In the settings of the router, there are restrictions on visiting certain sites or a limit on traffic (a common practice for open networks in public places).
• There are problems on the provider's side.

After eliminating these factors, proceed with the diagnosis, which allows you to understand which device is hiding the cause of the problem.

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

Crashes in Android

Restart your mobile device. If the cause of the problem was a minor system glitch, 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 you resolve the Wi-Fi mismatch between your phone and router.

If removing the network did not help, check the status of the proxy server on Android. It must be turned off:

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

Increase

Another reason that the phone does not go online may be the wrong date. To check it 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.

Increase

After setting the correct date, connect to Wi-Fi. If the wireless network is really working, you should be able to access the Internet.

Checking and configuring the router

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

Quite a common situation: the user tries to connect to Wi-Fi from his phone, but nothing happens. After reviewing the information below, you will learn why this happens and how to solve the problem.

Initial phone check

Manufacturers are actively working to improve the stability of mobile operating systems, but from time to time any program crashes. That is why it is recommended to start solving the problem by checking the phone's performance. For Android, iOS and Windows Phone (Windows Mobile), the recommendations in this case are identical. Follow the sequence below.

1. Reboot your device and try connecting to Wi-Fi again.

2. Estimate the number of connection signal strength indicators. If there are less than 3, try moving closer to the router or other wireless Internet source you are using to improve the quality of the connection.

3. Make sure Battery Saver is off. Connect the network adapter if necessary.

4. Turn off Bluetooth. Wireless connections can operate in the same range, which is why interference is created.

5. Disable Airplane mode if it is active.

6. Try to activate access to information about your location and connect to Wi-Fi - the legislation of some countries blocks connection via wireless networks when the mentioned option is inactive.

If the WiFi connection worked before

If you have successfully used the now problematic network in the past, delete this connection from your phone's memory. To do this, go to the list of networks, click on the problematic connection for a few seconds (until the context menu appears) and delete the connection.

If all else fails, try connecting from your phone to any other available connection. Failure in this case will most likely indicate a breakdown of the radio module - only service center employees will help correct the situation.

Check if the connection is working. To do this, try connecting to it using any other device that has a Wi-Fi function. If the connection does not work, make changes to the router settings.

Important note! The procedure for entering the router settings varies depending on the manufacturer and model of the equipment. In most cases, to gain access, you need to enter the address 192.168.0.0 or 192.168.0.1 into the address bar of the browser. The default username and password is admin. If it doesn’t work, check the manufacturer’s instructions for the information relevant to your router.

First, try simply restarting the router - quite often they “freeze”, due to which access to the Internet is blocked.

The next course of action is as follows.

First, you must verify that the security key entered is correct. Try to enter the password to connect to the selected access point again, but more carefully, with the "Display symbols" (show password) option activated.

If you do not remember the password, check it in the router settings.

For example, the order of interaction with the D-Link router is shown. In your case, everything will be almost the same, minor changes can only affect the interface, the names of menu items and other little things.

Once on the router settings page, do the following:
click the "Advanced settings" button;
in the Wi-Fi window, open the "Security Settings" link;
in the "PSK encryption key" line, look at the password and make sure that this is the combination you enter when you try to connect to Wi-Fi from your phone.

Secondly, make sure the router settings are correct - you need to check if DHCP technology is enabled. If it is disabled, the phone will not be able to obtain an IP address, and therefore the connection will not work.

On the router settings page, click "Advanced settings" again and in the "Network" window, find the "LAN" category.

Activate DHCP if the feature is disabled by setting the "Mode" line to "Allow".

Save changes, restart your router and try connecting to Wi-Fi from your phone.

If this does not help, there are 3 options left:
call the provider's support service and find out if the Internet is working at all and if any changes have been made to the connection settings;
hand over the phone for repair;
take in repair / replace the Internet router.

If our instructions did not help solve the problem, then write in the comments and we will definitely consider your problem.
