Wifi does not see available networks. The laptop does not see the access point. The computer does not see the required wi-fi point
Owners of laptop computers are often faced with the fact that the laptop does not see WiFi router. This is quite serious and annoying problem, which baffles many, even experienced users. What could cause a laptop not to see the WiFi router?
There may be several reasons for this phenomenon, and each of them requires separate careful consideration. This problem may affect not only users of portable machines such as laptops and netbooks, but also owners of classic stationary systems having WiFi receiver. Therefore, the solution to such a popular problem will be relevant and useful to know for almost everyone who at least sometimes deals with computers or WiFi.
Connection problems - looking for the culprit
One of the most common obstacles that prevent a laptop from seeing a WiFi router is the unsuccessful launch of the WiFi module on it. It may even happen that the search available networks turns on, all points are within range, but as soon as you try to join, the system displays a connection error. These and similar complications most often occur on computers with Windows 7, namely this system most prone to causing WiFi connection problems.
Figure 1. Checking driver installation on WI-FI. First you need to check whether the driver is installed on Wi-Fi.
In addition to the computer's fault, one should not exclude the possibility of a faulty access point, i.e. router. Therefore, the first step is to determine what exactly caused the problem, who is the culprit - the computer or the router? Simple and effective way to determine this is as follows:
- Find a second computer and try to connect to the access point from it.
- From the suspected computer, try connecting to various other points.
This should determine which device is actually causing the problem.
If one computer does not see the router, but other computers and mobile devices connect to it freely, which means the problem is in this computer. Otherwise, if other devices are unable to connect to the router, and other access points do not cause any problems, you will still have to deal with the router.
Checking the drivers
In the case when WiFi does not connect due to the fault of the computer, the first step is to check whether it is running WiFi module and whether all drivers are installed on it.
To check the adapter you need to go to the Control Panel Network connections and turn on the adapter.
To do this, open the Device Manager (Computer - Properties - Device Manager), look for and open the “Network adapters” subsection.
We check whether there is a device there whose name contains the words “Wireless Network Adapter”, or “Wireless”, or simply “Wi-Fi”. You need to go to “properties” and see if it works fine. (FIG. 1)
If such a device is missing or does not work correctly, and there are unidentified devices, you need to reinstall their drivers. To do this, we find the website of the manufacturer of the laptop model, look for a suitable Wireless Network Adapter driver on it, download it and install it.
Incorrect automatic detection drivers by the system, or outdated drivers are a common case that can interfere correct operation wireless adapter.
Checking the operation of the adapter
You should definitely check if the wireless adapter is turned on on your laptop. As a rule, it is enabled/disabled by pressing a key combination, for example FN + F2. To make sure which buttons you need to press, find the key with the wireless network icon and press it at the same time as the FN key, or refer to the user manual for your laptop model. Some laptops have a separate switch to turn WiFi on/off.
Another way to check whether WiFi is enabled or not is through a network management program. From the Control Panel, go to the Network and Sharing Center, then select “Change adapter settings” on the left. The network adapters and connections window will open, in which you need to find “Wireless network connection" Right-click on the connection icon. If in the opened context menu There is an “Enable” item and the connection icon looks gray, click on “Enable”, the adapter should start.
Otherwise, if the icon is colored and there is a “Disable” item in the menu, it is recommended to restart the adapter, i.e. Click on “Disable”, wait a few seconds for the module to turn off, and then turn it on again. The connection icon in the notification area should look like the one in the screenshot. This means that the adapter is turned on and access points have been found. If a similar icon appears, but instead of a yellow asterisk a red cross is shown, it means that the module is running, but no connection points were found.
It is also quite typical that the computer finds available points WiFi but does not connect to them, instead trying to connect results in a "Windows could not connect" error. But at present, there is no universal and unambiguous fix for this error. Quite often the reason is incorrect settings router, such as incorrect security and encryption settings, or problems with IP address allocation.
One of possible ways, which helps in many situations is to reboot the router and computer. In some cases, clicking the "Troubleshooting" link in the error message box can help you fix the error. Another tip: go to the properties of the wireless adapter and disable it to save energy, because... the reason may be that the computer does not correctly manage the power to the WiFi module.
Quite often, a connection loss occurs after the laptop exits sleep or standby mode. This problem mainly appears on Windows systems 7 and Windows 8. In this case, the measure described above also helps, i.e. Prohibition of turning off the adapter to save energy. To do this, go to Device Manager, in the subsection network devices We find the wireless adapter, go to its properties through the context menu. In the properties window, you need to go to the “Power Management” tab and there uncheck the “Allow the device to turn off” option. Click OK and reboot the system.
A connection error will inevitably appear if in the properties WiFi connections the password and encryption type for automatic connection, and on the router one or both of these parameters have been changed. In this case, the system will try to connect to the router with the old parameters, and it, accordingly, will not accept them and refuse the connection. The solution to the problem is to delete the network with the old parameters and connect using the new ones.
Checking the router configuration
You can enter the router settings through Network connections, where we select the item “Network and Sharing Center” shared access", then, if necessary, change the router settings.
In the same case, when the router is at fault and rebooting does not help, there are several ways that can fix the problem:
- Do not use automatic channel detection, set it manually, check different channels.
- Change the type, frequency and region of the network.
- Do not use Cyrillic characters in the password and SSID name.
It’s not difficult to get into the router settings; to do this you need to do a few simple steps. First of all, the router must be connected to the computer with a network cable. It is possible to connect via a wireless network, but it is not as reliable and secure as directly via cable. Then open any Internet browser, enter address bar The IP of the router is usually 192.168.0.1 or 192.168.1.1; more precisely, you can find it in the instructions for the router or read it directly on the sticker on its case. By entering the router address, we get to its web interface.
To gain access you must enter a name and password, usually they are the same: admin. Sometimes they may differ, this should be indicated in the same place as the address - in the instructions or on a sticker. Once in the settings, you must first try to set them in accordance with modern standards:
- security type WPA/WPA2;
- WPA2-PSK version;
- automatic encryption;
- region of the USA or the Russian Federation.

It is recommended to change the name WiFi points and her password. Don't use Cyrillic, check your keyboard layout! Only names and passwords in Latin work correctly; numbers can be used. When you finish changing the settings, you should reboot the router. After this, the new settings will take effect, you can delete the old saved connection on the laptop and all other devices that previously connected to the router, and try to connect again.
As already mentioned, if after changing the password, type of protection or encryption, you do not delete the old one and create a new connection on the computer, the computer may refuse to connect to WiFi, displaying an error. To complete this procedure, you need to go to the Network and Sharing Center; this can be done from the Control Panel or through the network icon in the notification area. Having entered it, we find and click the “Manage wireless networks” link. Once there, select the network of the router on which the parameters were changed, right-click on it and select “Delete network” in the context menu.
Hi all! For many years now, the life of modern man has been inextricably linked with the global Internet. And with the increase in production and the introduction of small wearable electronics into life, wireless technologies data transfer. A person, simply put, loses touch with the world when his laptop cannot connect to an access point. Therefore, today we will try to figure out why the laptop does not see the wifi network and what to do in such cases?
Let's see for ourselves possible reasons, after which we will find a solution to problems with connecting to wi-fi.
Hardware problem
Before looking for a software problem, it's worth checking if there are any physical malfunctions, otherwise there are cases when the laptop has purely mechanical damage or defects. Therefore, if they write to you that no available connections, then first of all look:
- whether the desired access point can be seen by any other device, for example your smartphone (an inscription on a sign, a sticker or a friend’s story does not guarantee that the equipment that provides data transmission via Wi-Fi is turned on and functioning);
- whether the required module is installed in the laptop (this applies more to used PCs purchased, where dishonesty of the seller is possible), usually this is a small board that can be accessed from the outside back cover. There you should also check whether the two output wires are attached to the antenna;
- is the wireless module physically turned on (on many older laptop models this mode is activated special switch on the case), to do this you need to carefully inspect the case for the presence of buttons and switches.
- Problem with wifi router. If the laptop sees all networks except yours, then check whether the router is connected to the network and whether the main wire from the provider is included in it. Sometimes it happens that it is only half turned on. But in any case, check whether all the necessary indicators are lit on the router. But the truth is that this applies purely to your network. And if he doesn’t see anyone at all, then that’s another question.
Software problems
Once we are satisfied that the devices are present and functioning in the laptop and the access point, let’s check whether Wi-Fi is enabled by the operating system. In the newest Windows versions There is an “Airplane mode” item, the activation of which blocks all connections. Therefore, we turn it off. Typically this item is located on the right edge of the Quick Launch panel.
Almost all models use a combination of the FN keys and the image of an antenna on the keyboard. Often, such a button additionally has an LED that indicates the activity of the wireless module. Sometimes, for this combination to function, you need to install special software. You can find it on the manufacturer's website or on the included CD.
If the problem persists, look further. In " ", tab " Network and Network Connections", find the item " Changing adapter settings"and look for an active or inactive wireless connection there (they differ from wired connection name and icon).
After this, it will be easy to turn the icon into working mode. If there is an inscription “Disconnected", select it with the right mouse button, and in the menu that appears, select “Connect". If there is no such item, then we move on.
Same inside " Control panels" find " device Manager" and look in the branch " Network adapters» items containing the word Wireless or wireless (but not Bluetooth). The presence of icons next to them (a cross or exclamation mark) may indicate problems with the driver, the program that controls wireless module. Try right-clicking on it, then clicking “Enable”. If it doesn't work out, then we move on.
Installing (reinstalling) the device driver
Sometimes, your adapter simply cannot be routed correctly, so download the wifi driver and install it.
Software for the proper functioning of all parts of the laptop is present on the CD included in the kit, in a separate folder on the hard drive (DRIVERS). If there is no disk, then they can be downloaded from the manufacturer’s website. After launching the installation process will take place necessary files into the system, when finished, you should restart the computer.
It is worth noting that often installation only the required driver may not solve the problem, so you should install the entire software package. This happens due to the interconnection of different hardware in the laptop.
We fight viruses
No matter how strange it may sound, one of the reasons why the laptop does not see available networks is viruses. Therefore, it would make sense to run some kind of antivirus or like Dr Web Cureit or Kasperskiy Removal tools.
Block Wi-Fi Signal
The very last and most incredible point. Blocking technique wireless signals, from science fiction quickly reached stores, and thanks to the “Chinese manufacturer” it became available to anyone. Both security services and simply a disgruntled neighbor can block all Wi-Fi signals for a short time. You can determine this option by simply moving the PC to another location.
Theoretically, such blocking can be used by fraudsters to intercept data, computer credentials in Wi-Fi networks. In practice, this option of lack of communication on at the moment is very rare.
In conclusion it must be said. If none of the above steps help, then most likely there is a breakdown. personal computer, the correction of which is best left to professionals.
But if you are going to contact someone, then only through friends and acquaintances, as well as specialized services. They really know how to fix and configure everything correctly. But just never contact the masters with advertisements like “I live nearby, I’ll come quickly.” I wrote more about this in. Read it. I'm sure you'll like it.
Well, this is where I end my article. I really hope it helped you. If this is really the case, then be sure to subscribe to my blog updates, and also share the information with your friends on social networks. Good luck to you. Bye bye!

It's hard to imagine to modern man your life without the Internet, and even wireless. But it happens that the laptop does not see the wifi network, why this happens and what to do then, let’s look into it in detail!
Why the laptop does not see the wifi network: possible problems and their solutions
Let's go from the most likely to the most difficult - by elimination. Let's get started.
Most common
So why does the laptop not see the wifi network - this may happen due to the fact that wireless internet basically absent!
- Let’s make sure that there is wireless Internet in the coverage area by using other devices: a tablet, smartphone, laptop or PC and check whether they see wifi on the laptop. If yes, we follow further, if not, then he does not see wifi.
We found out that there is Internet, but the laptop does not see the Wi-Fi network, why - it means that something is wrong with our device, as a rule, and there are extremely banal solutions. - See if the adapter is turned on; as a rule, the indicator lights up on the keyboard:
![](https://i1.wp.com/besprovodnik.ru/wp-content/uploads/2017/07/noutbuk-ne-vidit-wifi0.jpg)
- the procedure helps in most cases, otherwise we are looking for another reason why the laptop does not see wifi.
The driver is an important component!
We urge you not to forget that the driver is the link between the hardware and the OS. Without this talented negotiator, everything works quite crookedly or does not work at all - this may be the answer to the question - why the computer does not see the Wi-Fi network. No matter laptop or desktop PC, external or internal connection adapter, general solution.
![](https://i0.wp.com/besprovodnik.ru/wp-content/uploads/2017/07/noutbuk-ne-vidit-wifi_00.4.jpg)
If Windows versions 10, we follow:
![](https://i2.wp.com/besprovodnik.ru/wp-content/uploads/2017/07/noutbuk-ne-vidit-wifi_00.8.jpg)
We see that the drivers are not installed:
- go to the manufacturer and download the appropriate drivers.
- install → restart system
- check, if it works, we’ll finish here, otherwise we’ll look for other reasons.
Let's adapt - adaptation!
There is such a word as adapter - this is the main opportunist in the name of the advent of the Internet, and if it is disabled, nothing will be visible!
Let's check if it is enabled:

Sees everything, but not what is needed!
Why doesn’t the computer see my Wi-Fi network, but catches everyone else - and this happens. Here you already need to understand the router settings. Let's take a closer look at Asus models, and for the rest we will write them in commands. First, connect to another available Internet - for example, you can distribute it from your phone.
![](https://i1.wp.com/besprovodnik.ru/wp-content/uploads/2017/07/noutbuk-ne-vidit-wifi_00.013.jpg)
Now, regarding TP-Link equipment:
![](https://i1.wp.com/besprovodnik.ru/wp-content/uploads/2017/07/noutbuk-ne-vidit-wifi_00.014.jpg)
What's in my name...?
One involuntarily recalls the words of the classic A.S. Pushkin. Don’t think this is a joke, sometimes there is an SSID conflict, your computer doesn’t see Wi-Fi, but everyone else does. And believe it or not, it turns out that his change and Voila are enough!
We change it using the example of an Asus router with screenshots:
![](https://i2.wp.com/besprovodnik.ru/wp-content/uploads/2017/07/noutbuk-ne-vidit-wifi_00.015.jpg)
If TP-Link:

Nuances!
Each laptop brand has its own utilities responsible for function keys, let’s look at one position in detail, so what to do if Lenovo laptop Doesn't see WiFi. We are talking about Energy Management software.
1. Reboot the router and check that the cables are connected correctly
When using a cable for connection, check which ports the network connectors are connected to. The Internet cable provided by your provider must be included in a separate slot. It is usually located some distance from the other ports or is indicated in a different color (often blue).
After this, reboot your router. This action should be performed regardless of how you connect to the router - using a wire or a wireless network (WiFi). To reboot the device, use the “Power” or “On/Off” button on the device itself. Press the button to turn off the router, and after 10-15 seconds press again to turn it on. In case there is no on the rear panel separate button to reboot, disconnect the device from electrical network by unplugging the power supply from the outlet. After 30-40 seconds, turn on the device again, and after it boots up, check if the computer can see the router.
2. Perform connection diagnostics
Launch the panel Windows management on the computer where you are having connection difficulties. In the Network and Control Center, select the menu item marked in the screenshot.
Find the required network adapter, right-click on it and run diagnostics. Windows will try to identify a problem that is occurring with the connection. If problems are successfully detected and corrected, the system will notify you that the problems have been resolved. Then reconnect and the computer will see the router.
Important! Network diagnostics may take several minutes. It is recommended that you do not interrupt the troubleshooting process.
3. Use a different connection type
If the previous steps did not help, try connecting to home network in another way. If you are using a cable connection, connect via WiFi, and vice versa. This method allows you to localize the error and for its further correction. Among the disadvantages, it can be noted that desktop PCs are rarely equipped with WiFi adapter, so you can often use this method only on a laptop. You can use a second computer for diagnostics. This will help determine where the error occurs - on the computer or router.
4. When using WiFi, check that the network name is open
The computer may not find your home WiFi if the network is configured as hidden. Such networks do not send messages to others wireless devices your name (SSID). Connect to hidden network possible after entering her name and authorization (if encryption is available). Check current WiFi settings can be done in the router's web interface. Connect to the router with a cable and make sure that the connection is established (the computer sees it). Turn the router over and on its bottom side look at the address for logging into the admin panel, as well as your username and password. Go to specified address in the browser, enter your details account and find your wireless network settings.
Among the settings there will be a checkbox responsible for the visibility of the wireless network name. In routers from different manufacturers, it is called differently, for example, “Make network hidden”, “Hide SSID”, “Hide network name”. On TP-Link routers the desired item is called “Enable SSID Broadcasting”, and you can find it in the “Wireless Mode -> Settings” menu wireless mode" Change this setting, reboot the router and try connecting again.
5. Make sure the Ethernet port on your computer is working
Connect the Internet cable directly to the computer, without using a router. If Internet access appears, the computer does not see the router due to problems with the router itself. Otherwise, if Internet access does not appear, the error may occur due to problems with the computer's network card. It is recommended to reinstall the driver network card or replace it.
6. Replace the network cable
Network cable failure is one of the common reasons, by which the computer does not see the router. Cable failure is usually due to physical damage, which is not always easy to notice. The cord can be damaged by children or pets, it can be crushed by a door or pinched by a baseboard. Try using a different Ethernet cable to connect your computer to the router.
7. Insert the network cable into another port on the router
The cause of the problem may be a failure of one of the device’s LAN ports. Modern routers are equipped with several Ethernet ports, usually four. Disconnect network cable, with which the router connects to the computer, from the input being used and connect to the adjacent one. If the computer still does not see the router, try plugging the cord into a different port. If the connection is successful, the corresponding LAN indicator on the router body will light up.
Unfortunately, many of us have encountered a problem when the laptop stops finding a wireless network, which creates significant inconvenience. Considering that the laptop can be used outside the home, the user may be left without the Internet at all. There can be many reasons for this little pleasant moment. But, as a rule, the problem is technical, or malfunction software. To understand how to deal with the problem, let's look at it in more detail.
In order to understand the causes of the problem and understand why the laptop does not find the WiFi router or home WiFi network, you need to know what WiFi is and understand how this system wireless communication arranged.
WiFi is the same local network, only without the need for cable installation. Connection to the network occurs through a signal that is transmitted via radio waves. This system gained popularity not so long ago. A dozen years ago, no one knew about it, and the signal distance was much shorter. To be precise, the signal can be sent over a distance of 100 km.
In addition, WiFi is a registered brand that is developing very actively. In 2014, data transfer speeds via WiFi should increase to several Gbit/s.
To put it simply, now this method network connections are very popular. Almost every laptop has a built-in sensor that allows you to use wireless network. At bus stops, in cafes or any other public places, owners install free points access, which increases the level of comfort of an establishment or public place.
The main reasons for the lack of WiFi
As mentioned above, the main reasons can be 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. IN best case scenario, figure out the reason bad work router.
Availability of WiFi on laptop and router
It’s worth starting with the very basics, which can be forgotten due to haste or inattention.
Make sure that the receiving antenna is turned on. If the WiFi button does not work, then the problem is obvious. Not all laptop models have this switch, but some do have it. Most often it looks not like a button, but like a latch. However, it depends on the manufacturer. The switch may have a signature or image of an antenna, which indicates WiFi.
If there is no such button on your laptop model, then you need to pay attention to bottom panel operating system, on the icon next to the time. The image should show whether the wireless connection is currently active.
It is possible that this icon on the panel next to the time is not there.
To check activity without using this icon, you need to:

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.
To do this you need:
- Click on the network icon in the lower right corner, on the bottom panel, next to the time.
- Select “Connect to a network” and select desired point access. Most likely, there will be more than one access point, since you can see neighbors or some other routers. But, in most cases, a password is placed on the access point, thus protecting it from unauthorized users.

The laptop does not see the WiFi network: the main reasons
Why doesn't my laptop see the WiFi network? Perhaps the solution to the problem is right in front of you and only takes five seconds of your time. But there are also more severe cases. Let's look at the most common options.
Router
It is worth making sure that the router is turned on. Its operation can be easily determined by indicator lights. After connecting, look at the corresponding icons in the instructions for the router and determine whether wireless connection.
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 take the router for repair. As a rule, it is easier to replace the router with a new one than to send it to service centers for inspection.
Drivers
As you know, any equipment requires software that guarantees stable work. If the laptop does not detect WiFi, then you should check the drivers. Even if they are installed, it is recommended to update them.
You can check drivers through the control panel. In the “device manager” section there is a line “network adapters”, which should contain the name of the router if the problem is with the drivers. Right-click on it and look at the driver version. Compare it with the real version, which can be found on the Internet.
If the version is outdated, then download a new one and install. It is best to download from official sources. Drivers for hardware are distributed by developers free of charge, and there is no point in risking the “health” of your operating system in vain.
Signal distance
If after searching for a network the answer appears: “No connections available,” think about the signal. In apartments, this option is not very relevant, since modern routers have a strong signal and distribute it quite far. But in private homes or other places where the distance can be quite large, the signal simply may not reach the laptop. Therefore, you should not be surprised if the Internet suddenly disappeared while you were walking around the house or yard.
Mac address
There are situations when I was able to connect, but the router does not see the Internet through my WiFi or has stopped seeing it. When using services from some providers, the user cannot simply change network adapter, since the Mac address changes.
The Mac address is written on each router and the user just needs to call the operator to new address tie in to replace the old one. You may be asked to dictate it in full or to specify only the last few values of the entire number.
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 wifi but does not connect. In addition, sometimes antiviruses interfere with creating a connection. If possible, it is better to try connecting to the Internet without a router first. If everything is fine, then the programs are not to blame.
In addition to those listed, there can be many reasons. Basically, the variety of reasons is due to problems with the operating system. Therefore, if all else fails, try reinstalling your operating system. Perhaps all the problems come from here.
The laptop does not see the WIFI network on Windows7/Windows 8/WindowsXP
For those who are wondering why the laptop does not see wifi Windows 7, first of all, you need to try manually turning on the wireless network.
To do this you need:
![](https://i0.wp.com/proremontpk.ru/wp-content/uploads/2014/09/Izmenenie-parametrov-adaptera-640x640.jpg)
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 the “On” state.
The wireless network when using Windows XP does not require manual activation and, as a rule, connects 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.

How to set up a wireless network
For comfortable use of the network, some users resort to settings. Usually enough standard settings, but if you want, you can delve into your personal account. It is through personal account parameters are changed.
The login and password are specified by the router manufacturers, and you can find this data in the instructions. The address that will take you to your personal account is also indicated there. It is best to replace the default data so that no one can use it.
All other settings are made on the laptop itself, and they are installed using the Network Control Center.
WiFi without internet due to Windows
There are rare cases when operating system does not want to detect a wireless connection and shows that there is no external network at all. This option may exist when using non-licensed OS. Some people prefer to use amateur assemblies, which do not load the system as much and allow you to squeeze more out of the hardware.
Another reason could be a clogged system. System folders, over time, become clogged unnecessary files and if you do not defragment, the processor will be increasingly loaded. Antiviruses also cannot keep a laptop clean forever.
In any case, all problems with the OS can be solved by a simple reinstallation. After reinstalling Windows everything should work. Thus, the solution to the problem lies only in the functionality of the router, enabled WiFi on the laptop, or the presence of the necessary software. If these points are observed, WiFi will not present difficulties and will delight the user with stable operation.
