Greetings, friends. In this article, we will look at why a laptop may not see the wi-fi network. First, it’s worth understanding (albeit briefly) what wi-fi is, what its operating principle is and what it usually requires for this.

So, to put it in accessible language, then wifi is nothing more than wireless way communication of digital devices. It’s important to understand that you can’t necessarily use it to access the Internet right away, it’s just a way of building wireless networks(such as bluetooth).

In order to access the Internet, this Wi-Fi network must be connected to a router (special modem), which in turn provides access to the global web (via a telephone, network cable or any other method).

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

2 main situations when you cannot connect to wi-fi

1. The reason is 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 his smartphone (tablet, beech), search for available Wi-Fi networks and connect to the one you need.

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 group) and cannot connect to a wi-fi network, for example, in a public place. This is correct, perhaps it was simply disabled or access was limited (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, the first thing you need to do is decide where the problem is, and then go deeper into solving it.

Reasons why a laptop may not see Wi-Fi

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

• To begin with, it’s worth noting whether Wi-Fi is turned on in the “beech”. This is 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.
• The connection has failed. 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 wifi indicator- it should burn.
• Is the driver installed and what is its version on the laptop. Very often, if the beech is new or the operating system has been reinstalled on it, then installation is required the required driver on Wi-Fi. If you do not do this, you will not be able to log into 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 and replacement here.
• The money on the Internet has run out. In such a situation, of course, you won’t be able to access the Internet via Wi-Fi. You just need to deposit money into your account and the problem will be solved.

Conclusion

As you can see, there can be quite a lot of reasons; we have considered only the simplest and most popular ones. Don't take it lightly simple ways solutions such as checking the funds in the account or rebooting the laptop, very often they are what help solve the current problem.

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

Today, portable devices are gaining more and more popularity compared to personal computers, and there are a number of reasons for this. Modern laptops, tablets and phones are not just compact in size. They communicate with the Internet via Wi-Fi, and this is important, because Wi-Fi networks are quite widespread today. It is available in cafes, restaurants, libraries, train stations and even in public transport. All this thanks to the Wi-Fi module found in portable devices. However, sometimes this wireless communication It doesn't work quite correctly.

A little about Wi-Fi coverage

The Wi-Fi network is wireless and based on IEEE-802.11. Today, data transfer speeds through this network can reach 600 Mb/s. Wi-Fi coverage has a number of positive aspects, namely:

• To connect to a phone, laptop or tablet, you don't need a cable at all. Thus, the amount of cash costs is reduced.
• The owner of a phone, tablet or any other portable device not limited to a specific place. The Internet can be used anywhere the user desires.
• Wi-Fi coverage can be used without problems by owners of phones, tablets and smartphones.
• Despite the fact that there is only one Wi-Fi network in the room, many users with a phone or tablet can simultaneously connect to it.

Reasons for Wi-Fi connection failures

The reason such as the portable device being too far from the connection point, that is, the router, is not worth mentioning. The main thing is to maintain the required distance. However, if a laptop, phone or tablet is located a few meters from the wireless router and there is no connection, then there are several reasons for this. So here are the reasons:

• Older laptop models have a special small button to turn on/off the Wi-Fi connection. Therefore, it is worth checking that the connection is simply turned on. In new models, you can use a key combination, for example, Fn and F2, to enable Wi-Fi access. The device documentation will provide further assistance.

• The next reason is damage to the drivers that provide high-quality Wi-Fi work module. The problem is easily solved by reinstalling the drivers, which can be downloaded using the manufacturer's official website. Other sites may offer low-quality products.
• Sometimes the adapter module does not work at all. This is caused by the lack special utility, which allows you to manage your wireless network. The utility can be found on the manufacturer’s website or installed from the disk included with the laptop.
• Sometimes WiFi connection completely inaccessible. This refers to cases when all devices recognize the network, but one of the devices does not. In this situation, you first need to turn off the router for 10-30 seconds and then turn it on again. Sometimes the problem occurs due to an unexpected failure in the router settings. All you need to do is configure it again. In this situation, the best assistance will be provided by the provider’s support service, because each provider has its own type of settings.
• It also happens that the signal is almost imperceptible and is characterized by a low level. At the same time, some devices recognize the Wi-Fi connection, but connection is still impossible. This situation may arise if the router is located quite far from the laptop, phone or tablet.

• Theoretically, the cause could be a breakdown of the Wi-Fi module in a laptop or some other device. Moreover, if the warranty is still valid, you can easily exchange the purchased product. If you have an old device, repairs can be very expensive. Therefore, many advise purchasing a Wi-Fi adapter external use, which is quite affordable.

So, it is important to remember that it is not enough to just purchase a router, connect the appropriate cable to it and connect to the Wi-Fi network. Setting is required, which is best left to a specialist.

A router is a kind of network “computer” designed to transfer data between devices that have different interfaces and protocols.

If the PC is unable to access the Internet or access the router settings page, you need to perform a number of operations with the router and PC.

Most often, a communication problem with the router is determined by the messages “ Network cable Not Connected" or "Without Internet Access" as a crossed out image or exclamation mark in the notification area of ​​the taskbar.

Step 1. The first thing you need to do in this case is to check whether the connectors of the network (LAN, Ethernet) cables are correctly connected to the ports (connectors) of the router.

The router port labeled “INTERNET” or “WAN” is used to connect the cable coming from the Internet provider. This port is usually marked with a different color on the router and is sometimes located some distance away from other ports.

The PC and the router, in turn, are connected by an Ethernet cable, one end of which is connected to the RJ-45 connector on the PC, and the other to one of the LAN ports of the router.

Step 2. Reboot the router, because it is characterized by "". To do this, press the “On/Off” or “Power” button on the device. The router lights should turn off. After 15 seconds, press the router's power button to turn it on.

Reference! If there is no power button on the router, disconnect it from the 220V network for a short time and turn it on again after 30 seconds.

Step 3. Test Internet access. If communication with the router does not appear, this may be due to a failure in the network settings. To eliminate them, you need to run connection diagnostics.

1. Press the combination “Win ​​+ R” on the keyboard (“Win” is located to the left of “Alt”).

   

2. In the window that opens, type “control” and click “OK”.

   

3. The “Control Panel” will launch. If sorted, click on “View network status...”. If icons are displayed, select "Network and Sharing Center...".

   

   

4. Click “Change adapter settings” on the left.

   

5. Right-click on the network icon, and left-click on “Diagnostics” (“Fix”).

   

Windows will analyze the network status and identify problems, reporting problems that have been fixed or problems identified.

Step 4. Reconnect to the network. If the result is negative, replace, if damaged, the LAN cables connecting the PC and the router. Cables can be damaged by being kinked or caught by furniture.

Step 5. Reconnect. If there is no connection, there is probably a problem with the PC's network card. It is recommended to reinstall its driver or replace it in case of malfunction. This is especially true if the Wi-Fi connection is working.

Windows will find and update the board driver.

Step 6. If there is no connection, connect the provider cable directly to the PC connector and configure the Internet according to the recommendations specified in the agreement with the provider. This will ensure that the Ethernet port on the PC is working properly.

Note! It is also possible that the access problem is occurring on the ISP side.

If the Internet appears, it means that the fault is localized in the router and it needs to be reset to default settings.

Resetting the router to factory settings

Let's consider such a reset using the Linksys WRT160NL router as an example. Please note that the name, password and IP address of the router are unique for this device.

Reference! To find out the name, password and IP address of the router, you need to refer to its documentation (including its label) or find out this data via the Internet.

Step 1. Disconnect the computer and router from the 220V network.

Step 2. Disconnect all wires from the router.

Step 3. Turn it on and wait 1-2 minutes until it loads completely.

Step 4. Press and hold the reset button with a thin object (e.g. a paper clip) for about 5 seconds. The router reset button is located at the bottom right of the product label (marked in red). Release the button and wait for the router to reboot and start for 2-3 minutes.

Step 5. Turn off the router.

Step 6. Connect one PC to the router. To do this, insert one end of the LAN cable into the connector on the PC, and the other into port 1 of the router. Turn on the router and wait until it boots up for 1-2 minutes.

Step 7 Turn on PC. Turn off Wi-Fi if it is turned on on your computer. Usually, to turn Wi-Fi on or off, you need to press one of the “F1”–“F12” buttons, which has an “antenna” icon, sometimes together with the “Fn” button, or slide a special switch.

After resetting the router to factory settings, to check its connection with the PC, you need to run the “ping” command.

Step 8 Press “Win ​​+ R” on the keyboard and type “cmd” in the menu that opens, clicking “OK”.

Step 9 Enter “ping 192.168.1.1” in the window that opens and press the “Enter” key. There will be 3 or 4 lines starting with either “Reply from” or “Request timed out”. If the line says “Response from,” then the computer sees the router.

Reference! If you receive the message “Request timeout exceeded”, and the network card and the LAN cable connecting the PC to the router are working, this means that the router is faulty and requires repair.

Step 10 Open your browser and type the router IP 192.168.1.1, press the “Enter” button.

Step 11 In the login menu, leave “Username” blank, and enter admin in the “Password” field. Click "Login".

The settings interface will open.

Step 12 Try setting up the router using the installation CD or manually according to the provider's instructions and see if it can work normally.

Step 13 When the router is operating normally, exit the browser. The router is OK.

Reference! If you receive a “Response From” but the login menu and router setup page do not open, this means either the router is faulty or its firmware is faulty.

In this case, you need to use the Linksys tftp.exe program to start the router by updating its latest firmware.

Important! After updating the firmware, repeat the steps described above, starting with “ Step 1."

Updating the router firmware

Step 2. Click on the found equipment on the left.

Step 3. Click “Downloads\Firmware”.

Step 5. Click “Agree”. The download of the firmware file will begin.

Step 7 After the page loads, click on the word with the download link “here” (“here”) in the line “i. TFTP Utility - To download the TFTP utility, click here."

Note! The downloaded file can be opened in the “Settings” - “Downloads” parameters.

Step 8 Launch installation file Tftp.exe by left-clicking on the “Open” option.

Step 9 Enter 192.168.1.1 in the “Server” line and admin in the “Password” line.

Step 10 Click the select button (with three dots) in the “File” line, click on the downloaded firmware file in the menu, then “Open”.

Step 11 Click “Update”.

A firmware update indicator will appear and, upon completion, a message indicating that it was completed successfully.

Step 12 Enter 192.168.1.1 in the browser search and click “Enter.” The login menu will appear. Leave the “Username” blank, and enter admin in the “Password” field. Click "Login".

The router settings page should open and access to it should be restored.

The process of setting up a wired network router

Internet providers use several protocols for user connection:

• (issued) IP address (DHCP);
• fixed user IP;
• PPTP (point-to-point connection);
• L2TP (layer 2 tunnel);
• PPPoE (link layer).

Before connecting, you need to find out what protocol the provider uses, as well as (if available) the user name and password. Typically this information is provided in the contract concluded with the provider.

If DHCP is used, which happens in most cases, then the Internet should work immediately after connecting the router to the cable from the provider, because Routers are configured for DHCP by default. If another protocol is used, you need to register it in the router.

Let's look at using the PPPoE protocol using the TP-LINK router as an example.

Step 1. Connect the router to the PC and the provider's cable. Turn on both devices.

Step 2. Right-click on the connection icon, selecting “Network and Sharing Center...”.

Step 3. Click on the "Ethernet" option.

Step 4. Right-click on the “Connection…” shortcut, left-click on the “Properties” line.

Right-click on the “Connection...” icon, left-click on the “Properties” line

Step 5. Left-click on the line “TCP/IPv4” (in Win XP – “TCP/IP”). Click Properties.

Step 6. Left-click the lines “Obtain an IP address automatically”, “Obtain a DNS server address automatically”. Click OK.

Step 7 Launch your browser, enter 192.168.0.1, press Enter. In “Name...” and “Password” type admin. Click "Login".

Enter 192.168.0.1 into the search field of the browser, press “Enter”, in the login window type admin in both lines, click “Login”

Step 8 Select “Network” – “WAN” on the left.

Step 9 On the right in the drop-down list, select the type “PPPoE/Russia PPPoE” in the “WAN Connection Type” line. Enter (check) the remaining data shown in the photo below. Click "Save".

Step 10 Click on the “Status” section on the left and write down the Mac address of the router, which, if necessary, must be reported to the provider.

Wi-Fi setup process

Step 1. Click on the “Wireless” – “Wireless Settings” section on the left.

Step 2. In the “Wireless Name” line, specify the name of the network that will be displayed by the router for connecting to Wi-Fi. Enter (check) the remaining data indicated in the photo below. Click “Save”.

Step 3. Click on the “Wireless Security” subsection on the left.

Step 4. Scroll down the page and enter (check) the information indicated in the photo. Enter the Wi-Fi connection password in the “PSK Password” line. Click “Save”.

The router's connection to the Internet is complete.

Is your computer terribly slow?

Many people are familiar with the annoying situation when the operating system slows down and slows down, sometimes so much that it loses important data due to the impossibility of saving it. There are ways to get rid of these problems, but it is better not to fall into them.

Helpful steps in this case:

1. Scan your computer for viruses. If your PC is constantly slowing down, it most likely contains malware, adware or virus. A scan will identify the problem and usually fix it.

   

2. Get rid of unused programs. It is better to remove unnecessary software along with entries that can slow down your computer.

   

3. Clear the registry. This can have a big effect, and it is better to do the cleaning using specialized software, because... manual cleaning requires special knowledge.

   

4. Defragment hard drive. This will allow you to collect files “scattered” on the disk, which will speed up the OS access to them.

   

5. Don't multitask too much. The user can be productive when working with only a few programs, and the likelihood of the PC slowing down will be significantly reduced.

   

6. Update equipment. Computers on average are designed to last up to 5 years, as technology develops very quickly.

   

7. Reinstall the operating system. This is an extreme measure, but sometimes the only one that brings back the “fast old” PC.

   

As you can see, all that usually needs to be done if the computer “slows down and freezes” is to give it a little attention from time to time, which only takes a few minutes.

Video - Why the Internet does not work on the computer

Hi all! For many years now, the life of a modern person has been inextricably linked with the worldwide 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?

Characteristic causes and their elimination

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 is worth checking whether there are any physical faults, otherwise there are cases when the laptop has purely mechanical damage or defects. Therefore, if they write to you that there are no connections available, 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;
• whether the wireless module is physically turned on (on many older laptop models this mode is activated by a special switch on the case), for 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 you are satisfied that the devices are present and functioning in the laptop and the access point, let’s check whether Wi-Fi is turned on operating system. In the newest Windows versions There is an item “Airplane mode”, the activation of which blocks all connections. Therefore, we turn it off. Typically this item is located at the right edge of the panel quick launch.

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 a wired connection in name and icon).

After this, it will be easy to turn the icon into working mode. If it says “Disabled”, 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 the 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 proper functioning of all parts of the laptop are 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, you should restart your computer when finished.

It is worth noting that often installing 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. Technology that blocks wireless signals quickly made its way from science fiction to stores, and thanks to “ Chinese manufacturer» 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 scammers to intercept data and credentials of computers on a Wi-Fi network. 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 really contact someone, then only through friends and acquaintances, as well as in 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!
