If the problem is in the network adapter driver
To check if the required drivers are installed on the laptop, you must perform the following steps (the procedure is the same in all versions of Windows):
- In the “Start” menu, select “Control Panel” and go into it.
- In the “Control Panel” go to the section “System and Security”
- In this section, in the “System” subsection, select “Device Manager”
- In the window that opens, look at the list of devices and determine if there is an item “Network adapters”.
If the network adapters are NOT displayed in the device manager, then there are no drivers needed to connect to Wi-Fi. They can be downloaded quickly and free of charge from the official website of the laptop manufacturer, and then installed on a PC. After installing the utilities, the problem will be resolved.
DOES NOT connect to Wi-Fi on the phone (iPhone and Android)
If attempts to connect the phone to available Wi-Fi have not been successful, the problem must be looked for in the gadget itself or in the router. In such cases, the mobile device may NOT see the network, but if it finds it, then after entering the password, the connection does not occur.
The most common problems when connecting to Wi-Fi on your phone:
- Authentication error;
- Obtaining an IP address does not occur;
- The desired network is not detected.
If the problem is the adapter is off
In some cases, a laptop user can accidentally turn off the network card by pressing the Wi-Fi on / off key combination. In this case, it is enough to turn the wireless adapter back on.
On different laptop models, this is done in different ways. on some you need to hold down the “Fn” key and the button with the airplane / antenna icon (this is how the key to turn on / off Wi-Fi is usually labeled), and on some there is a switch on the case for this purpose.
There is a universal way to enable the network card:
- Go to the “Network and Sharing Center” by right-clicking on the Wi-Fi icon in the notification panel
- In the menu on the left, select the item “Change adapter parameters”
- Find the item “Wireless network connection” and determine whether the adapter is actually turned off (the inscription “Disabled” is displayed below it)
- Click on “Wireless Network Connection” with the right mouse button and select “Enable”.
When the network card turns on, the laptop will immediately find all available networks, and then you can connect to your home wireless Internet.
Why the laptop does not see Wi-Fi
The reasons for not seeing Wi-Fi may be in the laptop itself or in the settings of the router. How do you know if the problem is with your laptop and not your router? Need to connect to Wi-Fi via other devices, smartphone or tablet.
If Wi-Fi doesn’t find your smartphone or tablet, the problem is probably with your router. And if other devices connect to the wireless network without problems, then something is wrong with the laptop settings.
Why the laptop may NOT see Wi-Fi:
- Disabled network adapter (a microcircuit that provides Wi-Fi reception and processing) on a laptop
- Lack of drivers / utilities for the network adapter
- Failures in configuration settings, due to which the NK cannot connect to the Wi-Fi network.
A network adapter, or as it is also called, a network card, responds to the reception of a Wi-Fi signal in a laptop. This microcircuit is installed in all modern laptops and very rarely fails.
But situations when after installing Windows or programs, the network adapter drivers “fly off” are quite common.
Smartphone Cannot Obtain IP Address
This problem is typical only for Android OS. There can be two reasons: the DHCP server is disabled, or Android has crashed. It is easy to determine which of them is relevant in this case, just try to connect from another mobile device.
If the problem persists, you must give permission to enable the DHCP server in the router settings. This option can be found under LAN or LAN. The new settings must be saved. If other phones easily connect to this Wi-Fi, you should try to restart your mobile device, the reason is.
Laptop or phone won’t connect to Wi-Fi. solution
The situation when a laptop does not connect to Wi-Fi is quite common and many users have encountered it. Fortunately, in over 90% of cases, the reasons the computer does NOT find a wireless network can be fixed. The main thing is to correctly establish the cause, and then make the necessary settings.
No internet access or connection limited
Another common problem with Wi-Fi on a laptop is that the device cannot be connected. when you try, the message “Network connection error” appears on the screen. In this case, first you need to select the item “Troubleshooting” in the window of this message. The OS will most likely fix the problem itself.
If, however, through the “Troubleshooting” to achieve the desired result, it is likely that the problem is that the current set settings do not match the saved ones. In this case, you should try to delete the connection in the “Network Control Center”, restart the router, and then create the connection again.
If the phrase “Authentication failed” or “WPA / WPA2 saved” appears on the screen, it is most likely that the password was entered incorrectly. Otherwise, you should try to restart the router, and if it does not help, then delete the network from the phone’s memory, and then reconnect to it.
The phone still does not see the network
The reason is most likely in the Wi-Fi settings of the router. If shutting down and rebooting does NOT change the situation, it is worth trying to change the router settings. Most often, changing the network channel and region helps.
In the router settings, you must set a static channel and another region. You can try to put the US region, and if the static channel was configured earlier, you should put Auto. This failure may NOT affect second previously connected home devices that are working normally and the new phone cannot be connected.
If all of the above problems are eliminated, and other phones easily connect to Wi-Fi, the prerequisite for difficulties may be a failure of the operating system of the gadget. In most cases, the matter is limited to a reboot.
It so happens that the problem occurs after replacing the battery, glass or phone case. In such a situation, it is necessary to take the smartphone to the workshop, perhaps the master forgot to connect the antenna or the Wi-Fi module itself. Hardware damage to the module cannot be ruled out either, but it can also be identified and eliminated in the workshop.
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”), Searching for available Wi-Fi networks and connect to the desired.
In total, if your router is configured correctly, the second 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 restricted 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.
Laptop does not see wi-fi
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 enabled 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 just reboot it 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 the Wi-Fi. If you do not do this, then you will not be able to enter 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.
We solve the situation when the laptop does not see wi-fi
Hello friends. In this post, we’ll take a look at why a laptop might 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 NOT nothing more than a wireless way of connecting digital devices. It is important to understand that with the help of 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 (especially a 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).
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 in an account or overloading a laptop, very often they are the ones who help to 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 can 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.
DOES NOT 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, it will not be superfluous to try resetting the TCP / IP protocol parameters manually, for which it is necessary:
Open the Command line on behalf of the administrator (the “Start” menu. the “System Tools. Windows” section. select “Run as administrator” in the properties of the “command line” item);
At the command prompt of the window that opens, enter the command: netsh int IP reset c: \ resetlog.Txt
to restart a computer.
It should be noted 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 address of all network adapters installed in the system.
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 to second devices of 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. Such opportunities are made available thanks to the built-in laptop wireless LAN adapter using Wi-Fi technology.
Problems arising with the connection to Wi-Fi can cause serious inconvenience to the user when using the 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 a 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.
The laptop does not connect to wi-fi although wi-fi sees
If the laptop does not connect to the Wi-Fi of the laptop, but it sees Wi-Fi, then to solve the problem, you need to do the following steps, described in detail in the article.
What to do if your laptop won’t connect to Wi-Fi
If the laptop does not connect to Wi-Fi, then the first thing to do is restart the operating system. In view of 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 second application software), a situation may arise in which a your computer is really capable of fixing the problem.
The second step you need to take is to check the availability of the wireless network you want to access. You can do this by viewing the list of broadcasting wireless networks from a mobile phone equipped with a Wi-Fi module, or by requesting wireless networks, which displays 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 restarting the router, because 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 there are connection problems in several clients connected to it at the same time.
With the normal operation of the second 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 “My Computer” (This PC) Properties dialog box with the Windows Pause \ Break key combination 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. its direct presence in the “Network adapters” group, as well as that there are no system warnings (exclamation or question marks).
With the correct display of the name of the Wi-Fi adapter, it is possible to assume that the module is working properly, and the premise that the laptop does not see the Wi-Fi network is likely to be incorrect connection settings. Otherwise, to fix the problem, you may need to check the network adapter drivers.
The Wi-Fi module driver 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. Check the following points in the Wi-Fi adapter dialog:
- System messages in the “Device status” section on the “General” tab. make sure that the recognition device is working normally;
- Check the “Events” tab for system messages about the operation of the device;
- Make sure that on the “Driver” tab all fields 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, first downloaded the latest version of the software from the laptop manufacturer’s website. Before reinstalling or updating the driver, you must first remove the device from the system, click on the “Remove” button on the “Driver” tab, and then launch the updated version of the driver downloaded from the manufacturer’s website. As a rule, it has its own installer, which will perform all the further necessary installation procedures on its own.
Incorrect connection parameters can also be a prerequisite for which the laptop does not see Wi-Fi. The configuration 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, properly and configured by the router, the connected workstation should already get 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 second 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 second 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 placing a check box opposite the timeline “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, in the security settings of the router there must be an entry on the connection of 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 from the stickers on the back of the device (provided that the accounts have not been changed by the user). Upon successful authorization on the router, to facilitate its correct configuration, most devices predict 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 the Created special file, 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.
DOES NOT 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 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 can be creating 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 in turn:
- 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) to which all other devices are allowed. 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, the last 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.
The phone may NOT be detected by the computer due to viruses
It is trite, but all kinds of virus programs can block work with external mobile devices. Try to scan your computer with Dr. Web CureIt !, in some cases it can help.
There are no drivers for the phone on the computer
Although, usually, a computer with the latest OS detects and sees a smartphone via USB without problems, the opposite can be observed. Try to search for a driver for your smartphone on the network, sometimes a driver may come up for SIMilar models of this brand.
If the problem of detecting a mobile device by the computer has not yet been resolved, reset the settings
If, until now, your computer does not see the phone via USB, it should help resetting the smartphone using Hard Reset. Go to the settings of your phone, select the “Backup” menu item, and in it select “Reset data”.
But I warn you right away that you will lose your files and settings located in the internal memory of the phone (files on the SD card will remain intact), so this item should be used only as a last resort!
Reasons for not connecting your phone via USB
The whole complex of reasons for the problem that the NK does not see the smartphone through the USB cable, I would divide into hardware and software, and below I will list each of them, in parallel providing instructions for its correction. But before using the methods I have indicated, try restarting your computer and smartphone. this does not help as rarely as it seems. This problem mainly occurs with devices from Samsung, Lenovo, HTC, LG and Fly.
The computer does not see the phone via USB, but is charging
The computer does not see the phone via USB. software reasons
After describing the hardware reasons, we will list the main software reasons, if your computer still does not recognize a cell phone connected with a USB cable, follow the further instructions.
1. We work with the settings. We go into the settings of our device, select “Memory” there, click on the three dots at the top (Properties), select “USB connection to a computer” and put a tick in front of “Media device” (“USB drive”). If you have a checkmark opposite to use USB as a modem. Uncheck it.
USB connection settings to computer on Android
Windows Update (to download drivers for your phone) and New Device Discovery must be enabled on your PC. Remember to unlock your phone when connected to your computer, this is important.
If you are a conservative and have Windows XP, download the MTP (Media Transfer Protocol) for XP from the Microsoft website and install it on your computer.
2. If your USB.Ports drivers have failed, the computer may NOT see the phone. If the drivers for the USB ports are dysfunctional, the latter SIMply stop working. To fix this problem, install USB drivers from the “native” driver disk to your PC motherboard, or download the latest drivers from the motherboard manufacturer’s website.
Also, due to some reason, power may be turned off for a number of ports.
- Go to the “Power” section (Control Panel. Hardware and Sound. Power Supply)
- Select “Configure Power Plan” next to the power plan you are using;
- Then click on “Change advanced power settings”;
- Find “USB Settings” in the list that appears, click on the plus sign opposite;
- And then on the plus sign next to “Parameter for temporarily disabling the USB port”;
- Change the setting to Disabled for both mains and battery power;
- Click “Apply” and “Ok”.
Turn on USB ports
3. The device drivers have flown. Go to “Device Manager” and see if there is a question mark or exclamation mark in the “Portable Devices”.
Check if your device is there and make sure it is working properly by right clicking on it and clicking Properties. If it is there, or you are in doubt, uninstall the driver, Disconnect the phone from the computer, and then turn it back on, and let the system install the driver again. This may help solve the problem that the smartphone does not connect via USB to the computer.
Installing device drivers
Also, it will not be superfluous to enter the website of the manufacturer of your smartphone and download the latest drivers for it on your PC (for example, for Samsung there is a special software called Samsung Kies).
4. Install update KB3010081 (KB3099229). Windows 10 owners may need to install update KB3010081, which is responsible for working with Windows Media Player. This player is directly related to the normal operation of the MTP (Media Transfer Protocol) service, so download and install these updates.
Also, a common prerequisite may be an unreliable assembly of the OS itself on a PC. Only rearranging Windows to a more working version will help here.
5. Inoperative custom firmware. The desire of many fans to play with the firmware for their Android device can do them a disservice in the form of the device’s failure to work normally with the computer. Try restoring to stock firmware or recovering from a backup (if available).
Why the computer does not see the phone via USB, but is charging
Many users, when trying to connect a phone to a computer using a USB cable, are faced with the fact that the computer does NOT recognize the connected gadget. The connected device is charging, while there is no access to the smartphone itself and its internal content. I also encountered this synchronization problem, and in this material I will tell you why the computer does not see the phone via USB, and I will also share various methods for solving this issue.
Phones are connected via USB to computer
So why does the computer not see the phone via USB, but is charging. hardware reasons
1. The USB cable is damaged. It often happens that the cause of this dysfunction is damage to the USB cable itself. Cables of little-known or “non-name” manufacturers do not have a large margin of safety, and can fail literally in a couple of months from the beginning of operation, and as a result, the computer will NOT detect the connected phone.
Check if the USB cable is damaged
In addition, even the most reliable cables from global brands are susceptible to stochastic damage. they can be accidentally damaged during use, can be chewed by pets or spoiled by children. After that, first of all, inspect your USB cable for the possibility of mechanical damage, and, if the external cable is intact, try using it to connect your device to a second computer. If the device is NOT recognized on another PC. try replacing the cable.
2. The USB port on the computer is damaged. The USB ports used in a computer are also susceptible to various mechanical damage, including damage to the USB controller as well as the south bridge of the motherboard. Try to insert the cable into a different USB connector, if this does not help to fix the connection of the phone to the PC, follow the further tips.
Check if the USB port on the computer is damaged
3. Damaged cable jack on the phone. Has water got into the socket of the smartphone and is it damaged? If yes, then it needs to be replaced.
Turn off the battery, Pull the battery out of it for a few seconds, then turn it back, and turn on your device back.
As you can see, problems with the lack of visibility of the connected phone on the PC can be of both software and hardware nature, and there are a lot of such problematic factors. I would advise you to first pay attention to the probable mechanical damage in the cable and device, and only then switch to software methods.
In many cases, a SIMple restart of the smartphone (temporary removal of the battery), as well as working with the phone’s USB connection settings, can help. If all of the above does not help and the computer does not see the phone via USB, but is charging, then you may need to contact a qualified service center.
Checking Wireless Status
The next prerequisite for which the computer does not see wireless Wi-Fi networks is a disabled connection. How can I check this? First you need to open the Network Control Center. This is done differently on different operating systems. For example, on Windows8, you can just right-click on the network icon in the tray and select “Network Control Center”.
You can also open the service as follows. Press the WinR key combination and write control panel in the window that appears. Presses “Enter”. Thus, we launched the control panel. Now following this path. Network and Internet Network and Sharing Center. It should be noted that this service launch option is suitable for all versions of Windows. In the window that appears, we are interested in the item “Change adapter parameters”. It’s in the left menu.
In the window that appears, we see all the connections available on the computer. Find “Wireless Network” (if Windows7 is used, then “Wireless Network Connection”). If the label is gray, it means that the connection is disabled. To enable it, click on it with the right mouse button and select “Enable”.
After that, the system will turn on the connection and start searching for available networks. In some cases, if the computer still does not see the Wi-Fi network, then after the procedure done, you will need to turn on the module on the keyboard using the Fn key combination.
Why does my computer not see available Wi-Fi networks?
If the router is turned on and working, but the computer does NOT connect to the Internet and everyone does not see the Wi-Fi network, then you should go to the system settings. There can be many reasons for this error:
- Drivers for network equipment are not installed.
- Hardware error.
- Disabled wireless network connection.
- Defective Wi-Fi module.
In addition, there are other problems. However, it is SIMply impossible to describe everything. Therefore, we will analyze the most common connection problems.
Checking the driver for network equipment
What to do if the computer does not see the Wi-Fi network?
The first thing to notice is the driver. This is a special software that controls the operation of a particular equipment. Thus, if the driver for the network adapter is missing or does not work correctly, then the Wi-Fi module itself will not be able to work normally.
You can check this in the device manager. Click on the “My Computer” shortcut (you can find it in the file manager or in the “Start” menu) with the right mouse button and select “Properties”. In the window that appears in the left menu, you need to find and open the item “Device Manager”. Here we see all the devices that are connected to the laptop. Among them you need to find network equipment. How to properly configure the wireless Wi-Fi adapter read here.
Open the branch with network adapters. The absence of such a branch indicates that the driver for the Wi-Fi adapter is not installed on the computer at all. If the device manager displays network devices, then you should check if an exclamation mark is lit on any of them. If there is such an icon, then this also indicates the absence or incorrect operation of the driver.
In any case, this is solved by a SIMple reinstallation of the software, which can be downloaded from the manufacturer’s official website. Or, if a disc was included with the laptop, then everything that is needed can be installed from it. The Wi-Fi adapter in Device Manager is usually named Wireless Network Adapter. The driver is the main reason why the computer does not see the wireless Wi-Fi network. If the drivers are in order, but the problem is not fixed, then go ahead.
How to reinstall Wi-Fi driver on laptop:. Performing diagnostics
If you have followed all the above options, but the computer still does not see the Wi-Fi network, then you can resort to system diagnostics. To do this, open the Network Control Center and go to the “Change adapter settings” item.
Here we find the shortcut for the wireless connection and click on it with the right mouse button. In the window that appears, select “Diagnostics”. After that, the computer will start troubleshooting and fixing them on its own. After that, he will display a message about the detection of problems (if any) or tell you what to do next.
What to do if the laptop does not see the Wi-Fi network:. What to do if the computer does not see available Wi-Fi networks
Wi-Fi wireless technology is widely used throughout the world. Everyone knows about it, and there are practically NO people left who DO NOT use it. Connecting to an access point is extremely SIMple and does not require any knowledge. However, everything is not always so smooth. Quite often there are cases when the computer does not see available Wi-Fi connections.
But before proceeding directly to troubleshooting, you should delve a little into the principle of operation of this technology. The fact is that to connect to a Wi-Fi network, you need a router that acts as an access point. This means that in the absence of a signal, the first thing to check is the access point.
What does a hardware error mean? This is a problem directly in the board itself (network card). In other words, if the computer does not see the wireless Wi-Fi adapter, then this indicates that it is not working. This can happen for two reasons:
- The device is out of order.
- Driver problem.
We have already considered the second option above, and you know how to fix this problem. But if the drivers are installed, and the computer still DOES NOT find the Wi-Fi adapter, then it means that it burned out.
This happens due to overheating, for example, if you leave the laptop for a long time in bed or on some other soft surface by covering the air vents. In this case, the problem can be eliminated by replacing the failed equipment.
But this will require disassembling the laptop. Doing this yourself is not recommended. It is best to contact the service center.
Another reason why the computer does not see the Wi-Fi network is the disconnected antenna. This applies to those laptops that have already been disassembled for cleaning or second repair. It is possible that the master SIMply did not connect the antenna to the adapter, or did it incorrectly or badly. In any case, the adapter is SIMply not able to pick up the signal, even when in close proximity to the access point.
It is very rare, but it still happens that the antenna terminals are SIMply clogged with dust, due to which the contact disappears. In this case, you just need to clean them and everything will work.
The above are the most common reasons why the computer does not see the Wi-Fi network, and their elimination. But in practice, there may be other problems, the elimination of which requires an individual approach and special diagnostics, which only a master can carry out.
In addition, a prerequisite for the fact that the computer does not see Wi-Fi may be a long distance from the router and, accordingly, going beyond the range of the Wi-Fi network.
What to do if Wi-Fi does not work on a laptop:
