• Conclusion

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

So, speaking in an accessible language, then Wi-fi is 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 of building 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 (via a telephone, network cable or in any other way).

It follows from this that 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 ).

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

1. The reason is in your device
2. 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 a smartphone (tablet, "beech") from him, search for available Wi-Fi networks and connect to the desired one.

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 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 it.

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

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 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 must be installed on the wi-fi. If you do not do this, 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, by itself, it will not be possible to go to the Internet via Wi-Fi. You just need to put money into your account and the problem will be solved.

Conclusion

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 see wifi, what should I do?

In this article, we want to tell you why the laptop does not see Wi-Fi and how to quickly restore Internet access on your own. If you encounter a one-time WiFi error, cannot configure a wireless connection on a new computer, or no router is displayed in the list of available connections, this article will help you quickly get rid of the failure and return a stable Internet connection.

Possible reasons

Several system components are involved in creating a wireless connection on a computer or laptop:

• Network adapter. This element is present in all computers and is responsible for processing and sending any data over a local or global network. Also, the adapter processes all signals from the Wi-Fi router. If the component does not work, in most cases, this is the reason why it does not catch the Internet on the laptop;
• Hardware Drivers Is a set of utilities that ensure the correct interaction of the hardware and software parts of a network connection;
• Router(also known as a router) is the device itself that creates a wireless network through a cable or provider's modem.

It is enough to fail at least one of the above components, and you will no longer be able to connect to the Internet or face frequent interruptions in the connection.

There are cases when the laptop gives a regular one-time crash and it is enough to restart it to fix the error.

There can be a lot of reasons for a malfunctioning WiFi connection. These may include the following:

1 Freezing of the router or its breakdown;

2 Failure of the wireless adapter;

3 Outdated drivers or they are not installed in the OS at all;

4 The work of antivirus software;

5 Temporary technical failure on the side of the provider.

Note that the problem of connecting to the global network can be expressed in the fact that the laptop does not see only one router or does not recognize any access points at all (at the same time, you are sure that other gadgets detect routers within a given radius).

Below is a detailed step-by-step guide for each type of problem.

Turn on the WiFi module on the laptop

Often the reason why a laptop does not see available connections is its incorrect configuration. First, check the following parameters:

• Location of the laptop. The device must be within the range of the router. Typically, standard routers are capable of transmitting a signal within a radius of 50 meters. Note that brick walls and other massive fences can reduce WiFi signal range by 30% -35%;
• Other gadgets connect to access points without problems? If the Wi-Fi connection is not established on your smartphone or tablet either, the problem lies in the operation of the router. The computer does not see the network, but does it see the phone? Then you should check the operation of the component drivers and configure the router;
• Detect wireless networks must be enabled. To do this, move the pointer to the WiFi icon on the taskbar and click on it. If you see the following window "Wireless network is disabled", it means that network detection is temporarily inactive on the computer.

To activate it, click on the indicated tile with the antenna icon:

Fig. 1 - enabling the wireless network

A window of available wireless networks will appear, in which you can select the desired router. The laptop now sees the network:

Fig. 2. The result of activating the wireless connection

Enabling the network adapter does not always help in solving the problem, if this hardware component is not functioning properly, you will not be able to enable the wireless connection. What and how to do, read below.

You can also activate the wireless connection using the keyboard. To do this, simultaneously hold down the Fn + F2 key. Depending on the laptop model, the F8, F10, F12 keys can also be responsible for turning on the network.

For your information: In some laptop models, the WiFi module can be turned on with a switch located on the side of the gadget.

Fig. 3. Activating the wireless connection on the keyboard

On HP Pavilion notebooks, the wireless connection can be monitored using the F12 key, which has a built-in indicator light. If this indicator is highlighted in red, Wi-Fi will not work. Press Fn + F12 to activate it. As a result, it will be highlighted in white.

Fig. 4. Turning on the wireless light on HP keyboard

We check the performance of the equipment

Laptop sees the network but won't connect to the internet? So the problem lies in the operation of the network equipment. First you need to check that the equipment is installed and working properly.

To programmatically fix the network card, you need to run the Windows 10 device manager. Open the device manager by right-clicking on "Start":

Fig. 5. Opening Device Manager

A list of all hardware components connected to the PC will appear in a new window. Open the section "Network adapters" and select the item labeled "Network Adapter" (it may have different full names, it all depends on the laptop model and the type of network card).

1 Click on the object with the right mouse button.

2 Select Enable to activate the device if the hardware is turned off. If there are problems with the equipment, the system will offer to run the diagnostic tool.

Fig. 6. Enabling the adapter in device manager

3 Click on the object twice to get into the properties of the equipment, and check the status of the work in the column "Device status". The figure below shows the appearance of the properties window after enabling (the system detects that the driver is installed correctly for the Network Adapter).

Fig. 7. Checking the operation of the network adapter

Checking the operation of the router

The first and most common reason why a laptop does not see WiFi is a one-time failure in its work or a turned off router. The indicators on the switched on router always blink.

It is common for network equipment to freeze or malfunction, just like any other piece of equipment. The solution to the problem may be a banal reboot of the router.

If you were able to establish a connection with the router, but the connection says "No connection", we advise you to reboot the router. To do this, first press the "Power" button (located on the back of the modem).

Then unplug the device from the mains and wait a few minutes. After waiting a few minutes, plug the router into a power outlet and press the power button.

Fig. 8. Enabling / disabling the router

Now re-check the list of available networks on your laptop. The required network should appear in the list of objects. Following these simple steps will resolve the issue in most cases.

Installing and updating drivers

If you've recently installed or reinstalled Windows, the problem might be missing the correct drivers. Consider what to do if the laptop does not see Wi Fi, but other gadgets connect to the router without any problems.

Note that the operating system never displays information that there is a driver error or is not installed. The user can only independently see such a picture in the "Device Manager", an exclamation mark may appear opposite the component, indicating a problem.

Fig. 9. Device operation error in task manager

To install or update WiFi adapter drivers, follow these steps:

1 Go to Device Manager.

2 Right-click on the section "Network adapters" and select "Update hardware configuration".

Fig. 10. Automatic update of hardware drivers

3 To install the drivers manually, go to "Network adapters" and find in the name of the equipment Network Adapter, right-click, then select "Update Driver".

Fig. 11. Updating the wireless driver

4 In the opened Windows Assistant, you need to choose how to install or update drivers.

Automatic search- Windows will independently search for and install the necessary software for the hardware.

Search this computer- choose this method if there are already downloaded drivers for the network equipment, which must be specified.

Fig. 12. Built-in Helper window

If the automatic search for drivers does not bring results, then you can update the drivers - by downloading from the official website of the laptop manufacturer. For example, for owners of Hewlett Packard devices, just go to the official website hp.com and go to the "Support" section - "Programs and Drivers".

On all the official websites of laptop manufacturers, there is a section with drivers and programs for any model, bit and OS, just enter the name or choose from the list, depending on the search for the necessary components. The method described in the article is for the HP Pavilion laptop, but it is not much different from other laptops.

Another way to download drivers is to use the DriverPack Solution utility. With its help, you can automatically install drivers for all connected devices:

Fig. 14. DriverPack Solution Utility Window

After completing the installation of the drivers, turn on WiFi and check if the laptop can find networks.

Configuring the router

Often users are faced with a problem from the category "the laptop does not see my wifi network, while others can see it." In this case, you should configure the router, since its parameters may not be compatible with the laptop, and even this happens.

In addition to a short-term malfunction of the Wi-Fi router, the reason why the laptop does not see the network may be the incorrect configuration of the router or the incompatibility of some of its parameters with your PC. That is why the computer does not see a specific access point.

To configure the router, you should use another laptop or smartphone that connects to the access point without any problems.

Follow the instructions to check your router setup:

1 Connect the router to another device that "sees" it;

2 Now go to the browser (it doesn't matter if you are working from a phone, tablet or other laptop - all settings fields and methods for changing parameters will be the same for your router);

3 In the address bar, enter the address of the local host - "192.168.1.1" (or "192.168.0.1", enter the address without quotes). As a result of entering the correct address, an authorization window will appear in the settings.

Standard values: login- admin and password- admin. If this combination does not work, look at the bottom cover of the router itself - it contains the data for entering the configuration window;

Fig. 15. Bottom cover of the router

Fig. 16. Entering the router settings

Next, a window for configuring the router will open. Please note that its interface differs depending on the device model, firmware version or production region. The first parameter that we need to find and configure for compatibility between the router and the computer that does not see it is encryption type.

4 Go to the tab "Wireless mode" and in the "Security" field, select the simplest type of data encryption - WEP. This makes it easier for the computer to access the network. Standard WEP is sufficient for home use with a very low chance of an attacker compromising your network;

Note! In the settings of each router, it is also possible to completely disable the protection of the access point. You SHOULD NOT disable the type of encryption, as this will lead to the consumption of your traffic by other people, a decrease in the connection speed and an impressive increase in the amount of payment for the Internet.

Moreover, a law was passed on the protection of each wireless connection with a password for access.

Fig. 17. Configuring Router Encryption

The next parameter is the access password. We recommend that you check if you enter the correct code word when trying to connect to a WiFi router on a laptop. To view and change the password, go to the tab again "Wireless mode"- "Protection" and in the "Key" field, check the code word (connection password);

Fig. 18. Checking / changing the password for accessing the router

Also, a laptop may not see Wi-Fi due to a discrepancy in the number of supported communication channels on the computer and the router. Try to select different values ​​of this configuration in the settings of the router and reconnect to the network after applying each of them.

Go to the window "Wireless mode"- "Settings". Select the number of channels. To begin with, it is recommended to try connecting the "Auto" value, if it does not work, set the value manually, choosing the appropriate option. Such a WiFi setting will help solve all the problems associated with the incorrect operation of the router.

Fig. 19. Selecting the number of communication channels

Conclusion

Now you know what to do if WiFi is not working on your laptop. You can solve the problems and errors of a non-working Wi-Fi network using a step-by-step check of the operability of all network components and their correct configuration.

First, you should check the simple reasons: whether the router is turned on or not, whether the drivers are installed / updated, look in its settings for the correct password. To configure the compatibility of your laptop and router, change the type of encryption or the number of communication channels used.

If the laptop does not catch any wireless networks, activate the connection setup window or fix errors in the operation of the network adapter.

Thematic videos:

Here we are trying to answer the question of why the computer does not see the router, even if everything was connected as it should. Usually, they advise the following: reset the settings, press "F5" to refresh the page in the browser, just wait. We will not consider these well-known things. There are situations in which the router really cannot communicate with one of the PCs on the network, but the main thing is that the PC itself and the router are fully operational. If you do not know what this is about, read on.

Cloning MAC, Archer C-8

Let's say we have one computer and a router with gigabit LAN ports. Then, as soon as you clone the MAC address in the web interface, the connection between the router and the PC will be lost (moreover, completely). Such is the peculiarity of gigabit routers - they cannot work with a subscriber's PC if the MAC address was cloned from this particular computer. You will have to reset or replace the network card or its MAC. We will consider right now how the latter is carried out.

Managing MAC addresses of computers

Let's say we need to change the MAC address of the wired network card. You don't need any programs for this, you can get by with Windows tools. The sequence of actions will be the same for XP and Win 7:

1. Right click on the connection icon in the tray
2. Select the "Status" line, then click the "Properties" button
3. In the window that opens, we need the "Configure" button (immediately click it).

Access to network card settings

A set of tabs will open, where you will go to the "Advanced" tab and select the "Network Address" property:

As you can see, now there is no value, but you can set it, then set the selector to the upper circle and click "OK"

The question is what exactly needs to be asked here. First, let's find out what the default MAC value was.

Close the currently displayed window (press the cross). Where we clicked the "Properties" button, click on the "Details" button (true for Windows 7 users):

How to view the current address

The required value is displayed in the line "Physical address", write it down on a piece of paper. In Win XP, we would need to switch the tab (it was "General", we need "Support") and click the "Details" button. In general, you will need to specify a different sequence, similar to the value used, but differing from it by one digit. Happy settings!

Let's say, after trying everything, the user comes to the conclusion that the router is faulty.

In fact, there is no need to rush to such conclusions. Maybe the problem is with the PC's network interface, faulty signal cable, etc. This cord, the so-called patch cord, is fraught with surprises. Even when the LAN light is on on the router (including the one opposite the port being used), this does not mean that the patch cord is working properly. Try ringing the contacts on the plugs with an ohmmeter, or simply replace the patch cord.

Windows presents weird surprises

It will be, as you might guess, this is what: the computer cannot establish a connection with the router due to the operating system. It happens that it is useless to set the IP and DNS value explicitly - at least with fixed values, at least with the "auto" settings, the interface cannot be opened.

Configuring the PC: IP address, DNS

According to reviews, in these cases, reinstalling Windows helps, after which everything starts working right away. Experts, however, recommend trying to reinstall the network card driver. This is how it is done.

First of all, you must make sure that the driver can be reinstalled after uninstallation. You may need to have an installation disc (or download the driver from the Internet). The name of the device, more precisely, the name of the microcircuit, you will see if you open the "Device Manager". The sequence of steps to accomplish this: "Control Panel" -> "System" -> "Hardware" tab -> "Device Manager" button.

All devices present now

Well, to remove the driver, do everything that contains steps 1-3 from the previous chapter. Then go to the "Driver" tab, and click on the "Remove" button (it is there - the most recent). We wish you success.

We take the router out of the stupor

If everything is fine with the computer and the patch cord, you can try to "torment" the router itself. It is possible that this device is currently in firmware recovery mode. This mode can be activated either by the user himself or automatically (in case of damage to the firmware). How do I know if my router is really in recovery mode? Now we will answer this question.

Any D-Link device that is not equipped with an ADSL module, in the recovery mode, always remains available at this address: 192.168.0.1. But as a result of the fact that the DHCP server does not work in this mode, the PC does not receive an IP automatically. So we set the IP "192.168.0.2", the mask with the last "0" and go to the web interface. The browser should open a recovery page:

Firmware recovery page, D-Link

For all Asus, the symptoms of being in a non-standard mode will be different. Firstly, you will notice that even after booting, the “Air” indicator is off and the “Power” light is blinking (slowly) all the time. We also note that ASUS routers do not have a recovery page, like D-Link. ZyXEL routers do not have it either, and the "Power" light starts blinking with a period of 2 seconds.

If you come to the conclusion that the device remains in recovery mode, it is better to take it to a service center.

The firmware recovery procedure looks complicated if we talk about any routers other than D-Link. But the main thing is that the firmware itself, which will be used for recovery, still needs to be selected correctly (not even all branded image files are suitable).

As you understand, it will not be possible to simply return the device from emergency mode to normal mode - you need an image file with suitable firmware. There are no other options.

Regular process of opening the web interface

If the computer does not see the router over the network cable:

Often you come across questions that after connecting the router to the computer via a network cable, nothing happens. The computer does not react at all to the connection, and does not see the router. There really is a problem, and I want to tell you about possible causes and solutions.

As a rule, connecting a computer to a router via a network cable is as easy as shelling pears. I have an instruction according to which you will definitely do everything right. Usually, there are a lot more problems with connecting wirelessly. But, today we will talk specifically about the problems with the connection via a network cable.

So, if you connect a network cable to a router and a computer, and the computer refuses to somehow react to this connection, then first we need to find the reason. By the way, the Wi-Fi network from this router can work well and distribute the Internet. In our case, it is not the table that matters. Although, if the wireless network is not working, and the indicators on the router are not on as usual (especially if only the power indicator is on), then most likely your router is simply broken. If it works as usual, then the reason must be looked for in something else.

Why is there no connection between the computer and the router via LAN?

First of all, I advise you to check if you have correctly connected your computer to the router. When connecting a network cable to a computer (or laptop), one can hardly make a mistake, but when connecting to a router, it is possible (although difficult). On the router, the network cable from the computer must be connected to the yellow LAN connector. And only into him. There are usually 4 of them.

With this, I think there should be no problems.

Very often, it is the computer or laptop that is to blame for this situation. And not a router, as for some reason everyone immediately thinks. The fact is that network cards on computers can fail very simply and incomprehensibly. They burn very well. To check this, just connect a network cable to your computer from another router, modem, or directly from your provider. If, for example, when you connect the Internet directly to the computer, everything works, then the reason must be looked for in the cable, or, most likely, in the router.

Also, I advise you to go to the device manager and see how the network card works. Perhaps there are mistakes in her work. In this case, update the driver. Also, check if the network connection is enabled.

Also pay attention to the LAN connection indicators, which should be on your router.

If you know about other possible reasons why you cannot connect the computer to the router via cable, then share them in the comments!

THE COMPUTER DOES NOT SEE THE ROUTER

OR TRY THE REPAIR WITH YOUR HANDS

1. Reasons why devices do not see wi-fi

A Wi-fi router is required in order to connect to the Internet and transfer data between the network and digital devices. In the case when the computer does not see the router, there may be several reasons:

• the router or network cable is defective;
• broken power supply;
• the settings of the router are outdated;
• lost network connection settings;
• there are no drivers;
• the network card is out of order;
• failure on the line of the provider.

If the PC does not see wi-fi, then check the serviceability of the router, its power supply, and the possibility of a cable break. If all the elements are working properly, then you need to contact the provider to find out about possible accidents and failures in the Internet. Having refuted these causes of the malfunction, only hardware or software damage remains.

2. Software malfunction and settings failure

The most common Internet failures are due to incorrect settings, or an old version of the driver. Therefore, they need to be checked.

2.1. Setting up a network connection

To check the local network, you need to follow the following algorithm:

• Control Panel
• Network and Internet
• Network and Sharing Center
• View network status and tasks
• Local Area Connection Properties
• Internet Protocol Properties
• Enter the required information for the IP address, subnet mask, DNS server and gateway
• Save the settings

2.2. Driver update

Typically, the network card driver needs to be updated periodically. To do this, go to the control panel, select system, then - device manager. Browse the list of all network adapters, find the one you need and select its properties, then Hardware ID. Find the adapter code to download the corresponding driver for the update on the official website.

2.3. Configuring the router

If the router's settings are lost, then try to restore them to their default by going to a special address (192.168.1.1. Or 192.168.1.0.). After all the data has been knocked down, change it to match the data of the provider and the router model. Check if the IP address, gateway, DNS server are correct and save the data.

3. Replacing the network card

One of the reasons for the downtime of the Internet is the breakdown of the network card. In order to replace it, you need to purchase a new one that matches the specified system parameters and the type of connection.

Often you come across questions that after connecting the router to the computer via a network cable, nothing happens. The computer does not react at all to the connection, and does not see the router. There really is a problem, and I want to tell you about possible causes and solutions.

Every person using a personal computer often encounters the problem of connecting to Wi-Fi. There are situations when a laptop or other device does not see the wireless network, or it is incorrectly displayed in the list of available connections. And it also happens that the network is connected, but data transfer does not occur.

There are many reasons why this problem occurs. And in order to fix this, first you need to determine why such a malfunction could arise. The first reason this happens is that the laptop refuses to find any nearby Wi-Fi hotspots. The other cause depends on the source of the wireless network. And in such a situation, the computer, on the contrary, sees all the Wi-Fi zones, except for the one to which you need to connect.

It is always necessary to start diagnosing a malfunction by finding out the reasons. And then proceed according to the plan below to identify the culprit of the problem:

• Is the router working properly and is it available to connect point Wi-Fi? Can other devices with a Wi-Fi receiver see the router signal?
• Are there other sources of the wireless network nearby? And how do they appear in the list of network connections on a computer or smartphone?

Fixing the problem using Windows 7 or 8

When it turns out that the router is regularly transmitting a signal and other devices determine it, and the laptop does not see Wi-Fi even from neighboring routers, this indicates that adapter the laptop is out of order or is simply disabled by software or hardware. To finally be convinced of this, you need:

1. Start Device Manager and find the "Network adapters" item in the list.
2. The sub-item that appears should contain all network devices, in the list of which the wireless adapter should be present. Each laptop model can be labeled differently. Its exact name should be in the technical specifications, which can be found on the manufacturer's website.
3. It is also necessary that in the line with the name of the network device there are no additional yellow icons with the sign exclamations(this is a warning that the device is disabled or the wrong driver is installed on it).
4. You must first try to turn on Wi-Fi. To do this, call the context menu on the line with the name of the adapter and select the "Enable" command.
5. If this method does not help, then you need to try reinstalling the device drivers. To do this, you need to download them from the manufacturer's website and reinstall them.
6. You can also remove the adapter from the Device Manager list and restart your computer. And after turning on and loading, open the manager again and check if the Wi-Fi adapter was detected correctly. If it is displayed as "Unknown device", then install the preloaded drivers.

You can use another way to check the functionality of the wireless Wi-Fi card. To do this, go to the "Control Panel" and find the "Network Control Center ..." section there. Then go to the item "Change adapter parameters" in the left column of the window. When Wi-Fi is on and working normally, the “Wireless Network Connection” icon should not have red crosses and other additional symbols. If there is an inscription "Disabled" next to the adapter shortcut, then it can be started by calling the context menu and clicking on the "Enable" command.

Hardware problems

In addition, the Wi-Fi card can be turned on using the function keys and switches of the laptop. In this case, you need to look on the keyboard among the buttons (F1-F12) for the symbol denoting the Wi-Fi standard. And by pressing the Fn key along with this icon, you can start the device. Exact location this button or the switch can be found by referring to the manual for the notebook. These keyboard shortcuts are made to quickly turn off the Wi-Fi signal during an air flight, and may have an airplane symbol on the laptop keyboard. It all depends on the manufacturer and model of the device.

Another reason for the failure of the adapter may be a recent repair or cleaning of the laptop from dust. Probably, during assembly, the card could be damaged or incorrectly connected. In such circumstances, it is necessary either to change the adapter to a working one, or to install it correctly in the slot provided for this. And also it is worth paying attention to the wires going to it. Perhaps one of them could have been damaged during the assembly of the laptop after service.

There are times when a laptop does not see all Wi-Fi networks, while other computers and gadgets are normally connected to the router. The first step, of course, is to try rebooting your router. To do this, you need to disconnect it from the power supply for 20-30 seconds and wait until it is fully loaded.

If such a simple method did not help and the computer still stubbornly does not want to catch Wi-Fi, then you need to proceed in this way:

1. First, you can try changing the type of encryption in the wireless configuration of the adapter or router. And you should also try to change the number of the channel through which the signal is broadcast.
2. You can also rename the network, giving it a simpler name, consisting of ordinary Latin letters.

Another problem, due to which it does not catch Wi-Fi on a laptop, may be viruses in the operating system and technical malfunctions of the network card. Such a malfunctioning adapter is capable of displaying list of networks but don't connect to them. For example, due to corrupted software embedded in its controller.

However, the source of the problem can be not only a laptop, but also an incorrectly configured and working router. To solve problems with connecting to a wireless network, you need to:

1. Reset router software to factory default settings. And enter new values ​​into its settings.
2. Check what firmware is installed on the router, how up-to-date it is. If the router software is outdated, then you need to download a newer version and update the device.

It is recommended to periodically monitor the availability of new firmware and update the router when new firmware becomes available. This not only can improve its performance and remove some errors in its work, but also provide reliable security.

In addition to connection difficulties, there are also indirect problems that create a lot of troubles when using a Wi-Fi network. One of these inconveniences can be the slow speed of information transfer over the wireless network. And the reasons for her are:

1. A very large number of users connected to a Wi-Fi hotspot.
2. Incorrect router placement. A router located far away or poorly installed in a room may not "finish off" the Wi-Fi signal to the computer, moreover, if it is a laptop, with which people often move from one place to another. To do this, it is better to place the access point where there will be the same distance to it from all corners of the room or house.
3. Interference from other sources. Signal quality is often compromised by nearby sources of other wireless networks. They can interfere and slow down your connection. This is especially true when a more powerful router installed at neighbors serves as such a source. Another reason could be the nearby office buildings equipped with many of these access points.
4. Low-quality or cheap router issued by the provider. Many companies providing Internet access purchase inexpensive equipment to save their costs. This allows you to reduce the price for connection, but creates some inconvenience for the user. Therefore, before concluding a contract, it is better to consult with technical support and purchase a more powerful router.

The data transfer rate is also affected by constantly turned on torrents and the media files viewed on the network and online games. If you need to get the maximum connection speed, then at this time it is better to disable all applications consuming traffic.
