Laptop can’t see Wi-Fi connection

Instead of introducing

There are many adapters from different manufacturers, while they are still separately divided into external (USB) and internal. Of course, there are some nuances, but basically all the problems on them are the same, and the solutions for them are also the same.

So we read consistently, look for our problem, ask questions. together we will surely find a solution to any complex problem. Begin!

For almost every adapter model, we have a separate setup instructions on our website. Just use the search on our website if you have a problem with the setup.

No driver

Some adapters do not want to start without a driver. Especially on older operating systems. over, some old adapters do not want to start on new systems for the same reason. the manufacturer did not take care of releasing an updated driver.

In any case, the procedure for fixing the problem is as follows:

  • We connect the adapter. there must be at least some connection sound in the speakers, or visually it can be highlighted.
  • We are waiting. maybe the system will install the driver itself.
  • If nothing happened, there may be a disk with a driver included in the kit (it is already rare, but it happens) or the address for downloading special utilities for working with the adapter was written on the pieces of paper in the kit?
  • If nothing comes out, go to drp.su. download the program to check drivers and try to update with it (do not download unnecessary junk software with it, we are only interested in installing the drivers).

At the output in the Device Manager, you should see a normal detected wireless device, something like this:

laptop, wi-fi, connection

If you don’t have any wireless adapter in Device Manager, then the problem should definitely be looked for at the driver level or hardware failure. Don’t forget to test the work on another device!

If the adapter is quietly located here, but there is no way to search for wireless networks, we begin to dig in the direction of the operating system settings.

The computer does not see the Wi-Fi adapter, and the adapter does not see the network

Greetings, dear reader! In this article, we will consider common problems with Wi-Fi modules. why the computer does not see the Wi-Fi adapter, why the adapter itself does not see the network, why everything does not work at all. If this is about you. read the article further.

Some points in the article may not be disclosed and forgotten. after all, you cannot keep track of everything at once. If you have any additions, wishes, questions. welcome to the comments.

2 main problems

In my experience, there are only 2 main problems with adapters:

  • No driver.
  • Windows services problem.

On the built-in adapters, you could still look for whether it is enabled in the settings of the network adapters, but here, as a rule, with a physical connection, everything should already be enabled. So if none of the following works, you can suspect a hardware failure.

Before diagnosing a hardware failure, be sure to test the adapter on another PC or laptop. There were cases when the problem was deeply wired into the operating system and had to be updated (the modern “dozen” usually cope with the new hardware better, but not for everything old now you can find fully working drivers).

Operating system problems

These problems can manifest themselves in different ways:

  • The message “Not connected: no available connections” appears.
  • Special utilities that come with the adapter (if any) stop connecting to networks.

All the salt of these problems. the adapter seems to be working, but for some reason refuses to search for the network at all. And usually it’s all about the wireless network service. All you need to do is turn on the WLAN autoconfiguration service. For some, it is for some reason initially turned off, and this complicates the normal operation of the adapters. How to turn it on?

The interface of Windows 7 and Windows 10 diverges here, but I found a general option to enable service settings:

  • We right-click on My Computer (or on the desktop, or in the Start menu). Here we select Control:
  • Services and Applications. Services. On the right, we look for the “WLAN auto-configuration service” and check its work status. If it is turned off, you can immediately turn it on (and also set it to turn on automatically when the operating system starts):

Alternative for all Windows: click WinR, and there we write the services.msc command. the same services window will appear.

If nothing works after applying the parameters, try rebooting.

Sometimes the utility itself causes a conflict in the services, even if the service itself works fine. The recommendation for this case is to remove the utility, reboot, try to install clean drivers from the official website of the adapter manufacturer.

Software

Why are there still difficulties? The problem might be in the software. If you have System Restore enabled in Windows, then restore points will be shown in the log when installing programs. You can return the operating system to the day the network was up and let it see connections again. You need to select a state, click “Next”, follow the instructions. The Wi-Fi network can often disappear when the OS is updated, so sometimes you have to reinstall programs after the update, including for a wireless connection, and then the computer again sees what it needs.

Network problems

If you have installed the drivers for the keyboard, turned on the Wi-Fi module, but there is still no Internet, then open the “Control Panel”. Select “Internet Networks” and in “Sharing Control” select “Changes to adapter settings.” Here you will see a list of all adapters. Click on the “Wireless network” item. If the gray icon and the inscription “Disabled”, then there is no Wi-Fi icon in the system tray, which is why nothing works. In this case, you need to enable: right-click the context menu and select “Enable”. The wireless network becomes active. In case of an error, the launch of “Diagnostics of Windows Networks” helps. The system itself can find and fix errors.

If after that the computer does not detect an available network, then reinstall the drivers for the wireless network adapter. Open “Device Manager”, click on “Network adapters”, find the desired device. You need to uninstall and reinstall the driver. Drivers can be taken on the official page of your computer manufacturer or found a CD with a working driver bundled with your computer. After installing the driver, you need to turn on the Wi-Fi module and see the work. if everything was activated, we figured out why the network disappeared.

Sometimes it happens that the laptop does not see the wireless network after being repaired or after cleaning. The masters can turn off the antennas. Then you need to disassemble the laptop case and connect them or seek help from specialists.

First steps

What’s the first thing to do? You can reboot the router or computer on which the network has gone missing. Make sure to enter the correct password and not enable Caps Lock. If the passphrase is correct, but the computer does not connect, then you need to look for other reasons.

If the computer does not see any access points at all and / or has stopped seeing them: you need to check if the Wi-Fi adapter is active. You need to do this: on the computer keyboard, press the key combination “FnF3” (depending on the model and manufacturer, there may be a combination of “FnF2” or “FnF5”). The keyboard drivers must be installed for the keyboard shortcuts to work. On older models, the ability to see Wi-Fi is sometimes turned on with a separate button.

Router problems

If the problem is that the computer does not see only your router, but sees others, then you need to do the following steps. Find the settings of the router and check the operation of the Wi-Fi adapter. To do this, open a browser and enter http://192.168.1.1 or http://192.168.0.1 in the address bar. If it did not work out, the data on the ip-address and authorization in order to enter the page can be taken from the sticker attached to the back of the router case or on the manufacturer’s website. On the router’s page, you need to find “Advanced settings”, the “Wi-Fi and network settings” tab. You need to set the “Enable wireless connection” flag. If the flag is on, but for some reason the problem remains, then the last method is to change the channel on which the router is running. In order not to change the channel blindly, you can use the program “inSSIDer for Home”, which analyzes the frequency range of the channel. Channels 1 to 11 are the American standard for Wi-Fi, most devices can do work on these channels. They can be free from 11 to 13. When changing the settings, do not forget to click “Save”.

You can try to remove encryption, the setting is called “Authentication Method”, change to “Open System”. The problem might be the length of the key (“WPA Preshared Key”). If it is more than 20 characters, then the router will stop working with such a long key. Most likely, the key can be no more than 12-13 characters. You can also update the firmware right there: “Administration” section, “Update firmware” tab.

The computer does not detect a wireless Wi-Fi network

There are times when Wi-Fi stops being available on the computer. Why this happens and what to do in each specific case will be discussed in this article.

The problem can be of two types: the computer does not see the Wi-Fi network at all, or only your access point is not in the list of available neighbor networks. In the first case, the problem is most likely in the Wi-Fi device, in the second. in the computer on which the network disappeared.

Adapter malfunction

If all else fails and the computer still does not see the available networks, then there is a possibility that the Wi-Fi adapter could fail: it may burn out during operation, it needs good cooling. If it burns out, it will not be displayed in the “Device Manager”, this problem will be displayed in the “Windows Diagnostics”. It will need to be repaired or changed.

So, we have covered the most common sources of problems when a computer with Wi-Fi fails. Remember that any problem can be fixed if you know its causes.

The laptop does not see the Wi-Fi network and does not connect to Wi-Fi

Many users sooner or later face this problem. There may be various reasons why Wi-Fi does not work on a laptop. Perhaps you recently installed a new operating system, bought a new router, or upgraded an old one and others.

In general, if you also find yourself in such a situation, and you are unable to connect your laptop to a Wi-Fi network, then in this article we will consider several ways that should help you connect your laptop to Wi-Fi.

Let’s start with the simplest thing. restart your router. To do this, you need to unplug the power supply from the outlet, wait 10 seconds and turn it back on. Then reboot your operating system.

Network diagnostics

Do network diagnostics. Although many people will be rather skeptical about this advice, sometimes it can also help. Right-click on the wireless network icon in the tray and select “Diagnose problems”. Windows check, and if it finds a problem, it suggests ways to solve it.

If after diagnostics a message appears: The default gateway is not available, then in a separate article you can talk about how to solve this error.

If after that, the laptop still does not see Wi-Fi, check if the wireless Wi-Fi adapter is enabled on the laptop.

Find on one of the F1-F12 buttons the wireless network icon, mine is F2. Also, on the button itself, near the power button or touchpad, there should be a light indicator that indicates that Wi-Fi is on. Specifically, in my case, if Wi-Fi is disabled, the indicator light is on. To enable it, press the combination FnF2.

You also need to check that the network card is turned on. To do this, click on the wireless network icon in the tray with the right mouse button and select “Network and Sharing Center”.

In the next window, click “Change adapter parameters”.

If your “Wireless Network Connection” is grayed out, right-click on it and select “Enable”.

After that, the icon should become colored. This indicates that the network adapter is on and the laptop can connect to the Wi-Fi network.

Checking the WLAN autoconfiguration service

This service is responsible for the wireless network adapters, and if it is not running, the adapters will be unavailable, respectively, the laptop will not be able to connect to Wi-Fi.

We go to the “Start” menu and write to the search bar “Services”. Go to the appropriate item.

Then in the list we look for “WLAN auto-configuration service”. click on it with the right mouse button and, if it is disabled, click “Run”.

Driver Verification

Check the network adapter drivers. Click “Start”, write “Device Manager” in the search bar and follow the link found.

Expand the list “Network adapters”. The required adapter will be called something like: model name and “Wireless Network Adapter” (may be written Wi-Fi).

First you need to make sure it is turned on. Therefore, click on it with the right mouse button, and if there is an item “Engage” in the menu. click on it.

Now make sure that there is no yellow exclamation mark or red cross next to the adapter. If you have it as in the picture below, then everything is fine with the installed drivers. If you have one of the mentioned signs (in the picture I indicated with an arrow how it might look), you need to install or update the driver.

If you had a disk with your laptop with drivers for installed devices, use it and reinstall the driver. If this does not help, and the laptop still cannot connect to Wi-Fi, go to the official website of your laptop manufacturer, download the drivers for the network adapter from there and install them.

About installing drivers, you can read about Honor in the article: how to install a driver on hardware.

Also, to update or install missing drivers, you can use the free Driver Pack Solution program.

Checking router settings

Router settings can get confused, and not always through the user’s fault. The network password may have simply been changed.

If your wireless network icon is muted, and there is a yellow asterisk next to it, click on it with the mouse, select a network and try to connect to it, having previously found out if the access password has changed. The reason may be this.

Now let’s go to the router settings. There is already a detailed article on this topic on the site, by clicking on the link, you can familiarize yourself with it.

If, for some reason, they are lost, you need to configure them. In my case, you need to follow the link “Wireless Network Settings Wizard”. You may have slightly different menu items, it all depends on the model of the router, but you need to do the same.

Make sure you have a checkmark in the “Enable wireless connection” box.

Then you can change the network name and access password, select the wireless mode (b, g, n). This is what concerns the router itself.

Also take a look at the Network Information (LAN) section. You may need to change the settings here according to the provider.

For those who get an error when trying to connect: The network settings saved on this computer do not meet the requirements of this network, the article at the link can help.

I hope at least one of the tips helped you solve the question: why the laptop does not connect to Wi-Fi, and now your device is successfully connected to the network.

The laptop does not see wi-fi

2 main situations when you can’t connect to wi-fi

  • The reason is in your device
  • The problem is in the wi-fi network (that is, in the modem on which this network was created)

In order to eliminate problems with your laptop, you need to connect to the existing wi-fi network from another device, for example, from your friend’s phone. To do this, as usual, take his smartphone (tablet, “beech”), search for available Wi-Fi networks and connect to the desired.

As a result, if your router is configured correctly, your friend’s smartphone connected immediately and without problems, then you should look for the reason in your device (more on this below).

In the second case, you are sitting alone (or with a company) and cannot connect to a wi-fi network, for example, in a public place. It is correct, perhaps they just turned it off or limited access (for example, by the number of simultaneously connected devices). In such a situation, you need to contact the administrator. Or, if there are problems with the modem (yours, not your neighbor’s), then you need to either reboot it or reconfigure.

That is, first of all, you need to decide where the malfunction is, and then go deeper into its solution.

We solve the situation when the laptop does not see wi-fi

  • Introduction
  • 2 main situations when you can’t connect to wi-fi
  • Reasons why the laptop may not see the wi-fi network
  • Ways to Fix Lack of Wi-Fi
  • Conclusion

Hello friends. In this post, we will look at why a laptop may not see a wi-fi network. First, you need to figure out (albeit briefly) what wi-fi is, what is its principle of operation and what it usually requires for this.

So, to put it in an accessible language, then wi-fi is nothing more than a wireless way of connecting digital devices. It is important to understand that using it you can not necessarily go directly to the Internet, it is just a way to build wireless networks (such as Bluetooth).

In order to access the Internet, you need this wi-fi network to be connected to a router (special modem), which, in turn, provides access to the global web (through a telephone, network cable or in any other way).

Therefore. if your device (laptop, phone, tablet) has a Wi-Fi connection, then this does not mean that it will immediately connect to the Internet (it may seem obvious to someone, but some users may think that way).

Reasons why a laptop may not see Wi-Fi

Now let’s take a closer look at the main points of why the connection to the Wi-Fi network does not occur:

  • To begin with, it is worth noting whether Wi-Fi is turned on in the “beech”. It’s easy to check, at the bottom near the clock, click the corresponding icon. If no available networks appear there, then most likely it is disabled.
  • Connection lost. This can most often be due to modem errors. You can simply reboot or reconfigure it. To do this, just look at your modem and find the wi-fi indicator. it should be on.
  • Is the driver installed and what version is it on the laptop. Very often, if the “beech” is new or the operating system has been reinstalled on it, then the necessary driver needs to be installed on Wi-Fi. If this is not done, then you will not be able to log on to the network.
  • Wi-Fi stopped working on the “laptop”. The reason may be a breakdown of the corresponding adapter inside the device. There is only repair with its replacement.
  • Run out of money “on the Internet”. In such a situation, it goes without saying that you cannot access the Internet via Wi-Fi. You just need to put money into the account and the problem will be solved.

As you can see, there can be a lot of reasons, we have considered only the simplest and most popular. You do not need to be frivolous about simple solutions such as checking funds on an account or restarting a laptop, very often they are the ones who help solve the problem.

It is worth starting with the information presented above, and then moving on to deeper and more individual solutions to your question. This concludes the solution to the question of why the laptop may not see the wi-fi network, what to do in the first place in such a situation. Thank you for your attention, if you have any questions, then write them in the comments.

The laptop does not connect to WI-FI although wi-fi sees

If the laptop does not connect to the WI-FI laptop, but it sees Wi-Fi, then to solve the problem, you need to do the following steps, described in detail in the article.

Doesn’t connect to WI-FI on Windows 10 laptop

If the laptop does not connect to the WI-FI network and the user has taken the above recommendations, then it will not be superfluous to try resetting the TCP / IP protocol parameters manually, for which it is necessary:

open the Command Prompt on behalf of the administrator (the “Start” menu. the “System Tools. Windows” section. in the properties of the “Command Prompt” item, select “Run as administrator”);

at the command prompt of the window that opens, enter the command: netsh int IP reset c: \ resetlog.txt
to restart a computer.

It is worth noting that Microsoft has also created a specialized utility for the convenience of users (available at: https://support.microsoft.com/ru-ru/help/299357/how-to-reset-tcp-ip-by-using- the-netshell-utility in the “Easy fix” section) which allows you to interactively perform the above procedure for resetting TCP / IP parameters.

Also, in some situations, updating the IP address received from the router can help correct the situation with connection errors. To do this, enter the following two commands in turn at the command line prompt:

  • ipconfig / release
  • ipconfig / renew

This command will force the update of the IP addresses of all network adapters installed in the system.

What to do if the laptop does not connect to WI-FI

If the laptop does not connect to WI-FI, then the first thing to do is restart the operating system. Due to the presence of many Windows system services, on which the correct operation of the wireless network depends, under a certain set of circumstances (enabled automatic updating of device drivers, operating system, utilities preinstalled by the laptop manufacturer, as well as other application software), a situation may arise in which a reboot the computer is really capable of fixing the problem that has arisen.

The second step you need to take is to check the availability of the wireless network you need to access. This can be done by viewing the list of broadcasting wireless networks from a mobile phone equipped with a Wi-Fi module, or in the list of wireless networks displayed by Windows, for which you need to search for available wireless networks.

In the event that the desired name of the wireless point is absent, or the connection to it is unstable (there is no access to the Internet), one of the reasons may be a malfunction of the router itself, whose task is to create a wireless network with routing of connected devices in the right direction. As in the first example, sometimes it is possible to fix the situation by rebooting the router. as a result of power outages, overheating or overloading of the device itself, it is possible that some internal processes loop and, as a result, its improper functioning. The variant of a Wi-Fi router malfunction is more likely if several clients connected to it have connection problems at the same time.

With normal operation of other computers in the same wireless LAN, we will consider a number of measures to find out the reason why the laptop does not connect to WI-FI.

Incorrect operation of the built-in wireless adapter can be one of the reasons why the laptop does not see the WI-FI network. The correct operation of the Wi-Fi module can be checked in the “Network adapters” section located in the “Device Manager” of the operating system, to access which there are several ways:

  • open the properties dialog box “My Computer” (This PC) with the keyboard shortcut “Windows Pause \ Break” and go to the “Hardware” section. “Device Manager” or immediately go to the corresponding link (on Windows 10);
  • by calling the “Device Manager” snap-in with the “Run” utility (Windows R) in the line of which you need to type the process name “devmgmt.msc” and click “OK”.

In the opened “Device Manager” window, you need to make sure that there are no problems with the Wi-Fi module. it is directly present in the “Network adapters” group, as well as there are no system warnings (exclamation or question marks).

If the name of the Wi-Fi adapter is displayed correctly, it is possible to assume that the module is working properly, and the reason that the laptop does not see the WI-FI network is likely to be incorrect settings of the connection parameters. Otherwise, to troubleshoot the problem, you may need to check the network adapter driver.

The driver of the Wi-Fi module is also checked in the “Device Manager” snap-in, where in the “Network adapters” group you need to select the properties of the wireless adapter. In the Wi-Fi adapter dialog box, you need to check the following points:

  • system messages in the “Device status” section on the “General” tab. make sure that the device is recognized and is working normally;
  • check the “Events” tab for system messages about the operation of the device;
  • make sure that all fields on the “Driver” tab are filled in correctly (there are no entries “No data”, “Unknown supplier”, etc.).

To exclude incorrect operation of the adapter, due to the device driver, it is advisable to reinstall it, after downloading the most recent version of the software from the website of the laptop manufacturer. Before reinstalling or updating the driver, you must first remove the device from the system by clicking on the “Remove” button on the “Driver” tab, and then run the updated version of the driver downloaded from the manufacturer’s website. As a rule, it has its own installer, which will carry out all the further necessary installation procedures on its own.

Incorrect connection parameters can also be the reason why the laptop does not see Wi-Fi. The setup procedure is carried out in the “Network and Internet” section located in the “Control Panel”. To configure Wi-Fi, in this section, select the “Connect to the network” link and, having selected the required network, click on the “Connect” button. It should be noted that to connect to a Wi-Fi network, you need to know its full name and access key (password). Upon successful completion of the sounded procedure, a working and configured router, the connected workstation should already have access to the Internet.

If the tasks of connecting to a Wi-Fi network include the need to manage shared access to files, folders and printers from other computers on the local network, then the next step after successful authorization in the Wi-Fi network is to configure the Homegroup. This snap-in will allow you to make the required settings for sharing both files and folders, and other devices (printers, scanners, etc.).

You can check the password and change it, if necessary, in the “Network and Internet” section located in the “Control Panel”, where you need to click on the “Network and Sharing Center” link and select the property of the required connection. To view the account information in the opened dialog box of the network connection status, you must click on the “Wireless network properties” button. Password verification is available on the “Security” tab. By default, the password is displayed with hidden characters, which can be seen by setting the checkbox opposite the line “display entered characters”.

One of the reasons why the laptop does not connect to WI-FI may be the security setting of the router, namely the set MAC filter permissions. The MAC filter is configured directly in the section dedicated to the security of the wireless network, located in the settings of the router itself. To allow a laptop to use a Wi-Fi network through a router, an entry must be present in the security settings of the router for connecting the physical address of the network card of this device.

You can access the settings of the router by going to its IP address. The exact IP address of the router, as well as the login and password for accessing its settings, can usually be found by the sticker on the back of the device (provided that the accounts have not been changed by the user). With successful authorization on the router, to facilitate its correct configuration, most devices provide for the use of the “Assistant”, which allows you to step by step configure the network in such a way as to ensure the desired operation of all connected devices at the proper level in the shortest possible time. It is advisable to make finer settings for the router only after reading the operating manual for the router posted on the manufacturer’s website.

It should be noted that it is advisable to configure the router using a wired connection to it (most routers are equipped with a specially made network cable. crossover).

Helpful hint: Almost all Wi-Fi routers allow you to save the basic settings of the device in a special file that is created, do this always, before you change anything. This will allow you to instantly restore the previous state of the router, if mistakes are made during setup or failures.

Why Laptop Can’t See Wi-Fi. Typical Causes of Wi-Fi Connection Problems

Portable devices such as a laptop, today are closely related to the life of any modern person, being an indispensable tool for processing information of any nature. One of the main advantages of this type of computer, in addition to its mobility, is the ability to connect to the Internet or other devices on the local network (printers, other computers, file storages, etc.) regardless of the user’s location. at home, in an office, in a hotel airport, cafe or even a park. These capabilities are made available thanks to the built-in laptop wireless LAN adapter using Wi-Fi technology.

Problems with connecting to Wi-Fi can cause serious inconvenience to the user when using a laptop, greatly reducing its consumer qualities. The most common reasons include:

  • errors in the operation of network services of the Windows operating system;
  • incorrect operation of the Wi-Fi adapter of the computer due to its malfunction or incorrect functioning of the device driver;
  • changed (for example, by the network administrator) or incorrectly entered credentials to access a specific Wi-Fi network;
  • malfunction or incorrect settings of the Wi-Fi network router;
  • considerable distance from the Wi-Fi router or / and location near source of strong electromagnetic interference.

Let’s consider in more detail the most common situations, as well as ways to eliminate them.

Doesn’t connect to WI-FI on Windows 7 laptop

Finding the reasons why the laptop does not see Wi-Fi with Windows 7 installed is practically no different from the recommendations given for Windows 10. A feature may be the presence of warnings issued by the User Account Control (UAC) component. For the successful completion of the procedures, it is necessary to allow the actions performed in the above recommendations.

Another method that can help in solving the problem is to create another, obviously functioning Wi-Fi access point on a laptop.

The easiest way to create a software access point is to use the command line, at the prompt of which it is enough to enter the following commands one by one:

  • netsh wlan set hostednetwork mode = allow ssid = “Name of the created access point” key = “Password to access the created access point” keyUsage = persistent
  • netsh wlan start hostednetwork

This procedure creates a virtual Wi-Fi access point (Virtual WI-FI), access to which is allowed to all other devices. This will allow you to check the health and correct operation of the adapter installed in the laptop.

If you need to turn off Virtual WI-FI, just enter the following command in the command line: netsh wlan stop hostednetwork

In conclusion, I would like to note that if all the above recommendations are fulfilled and there are no positive results, an extreme option may be a physical malfunction of the devices themselves (wireless Wi-Fi adapter or router), which will require the involvement of specialists from a specialized service center.

Installing Applications

Today it is possible to download an additional application through the Play store that will help you configure the wireless network. From the recommended ones we offer Fix WI-FI, WI-FI Fixer and WI-FI Doctor. The programs will eliminate all the failures that have arisen, increase the download speed. The third program will even notify you if someone else connects to your network.

Writes “Saved Protected

It happens that after entering the password (or it is not needed), the network is saved, but there is no Internet connection. Most often, it is enough to overload the router to resume work, but sometimes you have to climb into the settings of the network equipment.

  • First of all, make sure you enter the correct Wi-Fi password.
  • Open the web interface of the router using the information provided on the equipment case.
  • Look at the specified region, change if necessary to the one in which you are.
  • Set the value of “Channel” from 1 to 10 instead of “Auto”.
  • Change “Encryption” and “Password”.
  • Try different variants of the “Channel Width”. first “Auto”, then 20 MHz, etc.

After the performed manipulations, find out the number of devices that are allowed to connect. Mark “0” means no restrictions.

Why the smartphone does not connect to the Wi-Fi router

First, determine if this problem has occurred only on your phone (Huawei, Honor, Samsung, Xiaomi, iPhone, Meizu, Asus, etc.) or there is no access to Wi-Fi in other gadgets (tablet, laptop). In the case of a single case, you need to look for the source in the gadget itself. If a problem occurs with all the equipment. in the settings of the router.

DNS problem

Hold down the WI-FI network and from the drop-down window click on the item “Change network”.

In the “Advanced Settings” click on the DHCP item and select the “Custom” value. Scroll down. Enter 8.8.8 and 8.8.8.4 in DNS1 and DNS2, respectively. Confirm saving.

Time and date

Open “Settings” in your mobile device by clicking on the “gear”. There you will see the “System” section, and in it “Date and Time”. Make sure the information matches your region. If the values ​​differ with the network, data transmission errors may occur.

Wrong password

With this error, the first thing to do is to check that the entered activation code is correct. Didn’t switch the language, didn’t change the case of letters, or made a mistake in one number. If everything is correct, to eliminate the source of the problem, use the following instruction.

Perhaps the router is far away and the network “does not reach” the connection point, or there is an obstacle in the signal path. In this case, move the unit closer.

  • See that the “WI-FI” function is turned on, and put a tick on “Auto connect” if it is absent.
  • Restart the router by pulling the plug from the outlet for 10-15 seconds and plug it back in.
  • Try “Delete” or “Forget” the network and reconnect to it.
  • Check if the RAM is overloaded due to a large number of active applications and requires a reboot of the smartphone with Android OS.

If the voiced actions are not useful, take the mobile device to the master in the technical department of your brand.

Removing programs

Remember, you may have recently installed third-party applications on your mobile device. Review everything, and if any program seems suspicious, it is better to delete it. Some programs may block your internet connection. Go to the application and click “Stop” to stop it. And then delete.

Firmware upgrade

Check for new updates for your router and mobile device. If there are any, please update. This may be the reason for the lack of connection.

The main reasons for the lack of WI-FI

As mentioned above, the main reasons can be roughly divided into technical and software. In the case of technical ones, the owner of a laptop will most likely have to contact a service center and spend money on repairing it. At best, deal with the reason for the poor performance of the router.

Checking available networks

The next thing to do is check the available networks. Perhaps the router simply does not reach the laptop’s antenna and for this reason it is impossible to connect to the network.

  • click on the network icon in the lower right corner, on the bottom panel, next to the time.
  • Select the “Connect to the network” item and select the desired access point. Most likely, there will be more than one access point, since you can see neighboring or some other routers. But, in most cases, a password is put on the access point, thus protecting it from unauthorized users.

Antivirus or third-party programs

Third-party programs installed on a laptop may conflict with drivers or interfere with the correct establishment of an Internet connection, which often happens when the device sees WI-FI but does not connect. In addition, sometimes antivirus software interferes with creating a connection. If possible, it is better to try first to connect the Internet without a router. If all is well, then the programs are not to blame.

The laptop does not see the WI-FI network: the main reasons

Why does the laptop not see the WI-FI network? Perhaps the solution to the problem is right in front of you and only takes five seconds. But there are also more severe cases. Let’s consider the most common options.

Mac address

There are situations when it was possible to connect, but the router does not see the Internet through my WI-FI or has stopped seeing. When using the services of some providers, the user cannot just change the network adapter, as the Mac address changes.

The Mac address is written on each router, and the user only needs to call the operator to bind the new address to replace the old one. You may be asked to dictate it in full, or to clarify only the last few values ​​of the entire number.

Router

It is worth making sure that the router is turned on. Its operation can be easily identified by the indicator lights. After connecting, look at the corresponding icons in the instructions for the router and determine if the wireless connection is active.

If the router does not respond at all, then the problem is purely technical. In this situation, you should look for a problem in the wires, power supply, or carry the router for repair. As a rule, it is easier to replace a router with a new one than to give it to service centers for inspection.

The laptop does not see the WI-FI network on Windows7 / on Windows 8 / on WindowsXP

For those who are wondering why a laptop does not see WI-FI Windows 7, first of all, you need to try manually turning on the wireless network.

    go to “Control Panel. Network and Sharing Center. Change adapter settings”;

In Windows 8, activity is checked through the “PC Settings” item. Next, you need to select the line “wireless” and move the slider on the right side of the menu to “On”.

When using Windows XP, the wireless network does not require manual activation and, as a rule, is connected, like Windows 7. It is enough to activate it through the control panel or through the wireless icon through the bottom panel of the system.
