The PC does not see the wifi network. What to do if the laptop does not see Wi-Fi

A router (router) is a kind of network "computer" designed to transfer data between devices with different interfaces and protocols.

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

Most often, a problem with the connection with the router is identified by the messages "The network cable is not connected" or "No Internet access" in the form of a crossed-out image or an exclamation mark in the notification area on the taskbar.

Step 1. The first thing to do in this case is to check if 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 ISP. This port is usually colored differently on the router and is sometimes located at some distance 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 go out. After 15 seconds, press the power button of the router 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 the connection with the router does not appear, this may be due to a failure in the network settings. To eliminate them, you need to perform connection diagnostics.

  1. Press the combination "Win + R" on the keyboard ("Win" is to the left of "Alt").

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

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

  4. Left-click "Change adapter settings".

  5. Right-click on the network icon, and left-click on "Diagnose" ("Fix").

Windows will analyze the network status and troubleshoot problems by reporting troubleshooting or identified issues.

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 kinking or clipping 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 in case of malfunction. This is especially true if the Wi-Fi connection works.


Windows will find and update the driver for the board.

Step 6. If there is no connection, connect the provider's 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 occurs on the side of the provider.

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

Resetting the router to factory settings

Let's look at 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 to 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 these 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 is fully loaded.

Step 4. Press with a thin object (for example, an unclenched paper clip) and hold the reset button for about 5 seconds. The router's reset button is located on the bottom right of the product label (marked in red). Release the button and wait 2-3 minutes for the router to restart and start.

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 the PC. Disable WI-Fi if enabled on your computer. Usually, to enable or disable Wi-Fi, you need to press one of the "F1" - "F12" buttons, which has an "antenna" icon, sometimes in conjunction with the "Fn" button, or slide a special switch.

After resetting the router to factory settings, to check its connection with the PC, you must execute the "ping" command.

Step 8. Press "Win + R" on the keyboard and type "cmd" in the launched menu by clicking "OK".

Step 9. Enter in the opened window "ping 192.168.1.1" and press the "Enter" key. You will see 3 or 4 lines starting with either “Reply from” or “Request timed out”. If the line says "Reply 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 properly, this means that the router is defective and needs to be repaired.

Step 10. Open a browser and type the IP of the router 192.168.1.1, press the "Enter" button.

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

The settings interface will open.

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


Step 13. Exit the browser during normal router operation. The router is working properly.

Reference! If you receive a "Reply From", but the login menu and the 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 with the latest firmware update.

Important! After updating the firmware, repeat the above steps, 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”. Downloading the firmware file will start.

Step 7. After loading the page, click on the word with the download link “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" options.

Step 8. Run the Tftp.exe installation file by clicking the left mouse button on the "Open" option.

Step 9. Enter 192.168.1.1 for Server and admin for Password.

Step 10. Press the selection button (with three dots) in the "File" line, click on the downloaded firmware file in the menu, then "Open".

Step 11. Click “Update”.

The Firmware Upgrade Indicator appears and a success message when completed.

Step 12. Enter 192.168.1.1 in the browser search, click "Enter". The login menu appears. 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.

Wired network router setup process

ISPs 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 username and password. Usually this information is given 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 with a 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 consider the use of the PPPoE protocol on the example of a TP-LINK router.

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

Step 2. Right-click on the connection icon by 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 on the lines “Obtain an IP address automatically”, “Obtain DNS server address automatically”. Click OK.

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

We enter 192.168.0.1 in the browser search field, press "Enter", in the login window, type admin in both lines, press "Login"

Step 8. Select "Network" - "WAN" on the left.

Step 9. In the drop-down list on the right, select the “PPPoE / Russia PPPoE” type in the “WAN Connection Type” line. Enter (mark) the rest of the 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, you need to share with your ISP.

Wi-Fi setup process

Step 1. Click on the "Wireless" - "Wireless Settings" section on the left.

Step 2. In the "Wireless Name" line, set the name of the network that will be displayed by the router for connecting to Wi-Fi. Enter (mark) the rest of the data shown 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 (mark) the data shown in the photo. Enter the password for the Wi-Fi connection in the “PSK Password” line. Click “Save”.

The router is now connected to the Internet.

Does your computer slow down terribly?

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's best not to get caught up in 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 a virus. Scanning 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 with specialized software, because manual cleaning requires special knowledge.

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

  5. Don't multitask too much. The user can be productive with only a few programs, and the likelihood that the PC will slow down is greatly reduced.

  6. Upgrade equipment. Computers are on average designed to last up to 5 years as technology advances very quickly.

  7. Reinstall the operating system. This is a last resort, but sometimes the only one that brings back the "old fast" PC.

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

Video - Why the Internet does not work on the computer

It would seem, what could be easier than connecting a router to a computer? Things are just for a couple of minutes. But sometimes the result can be completely unexpected, for example, the computer does not see the router, and it is impossible to enter the settings of the router parameters. What to do in such a situation? For those who want to try to fix the problem on their own, here are some simple tips. But first, a few words about the possible causes of the failure.

Why the computer does not see the router: possible reasons

As for the reasons, there can be quite a lot of them, from a banal incorrect connection to equipment malfunctions, including the router itself and the corresponding ports on the computer (physical breakdowns or software failures of the device itself will not be considered in detail).

However, the main prerequisites for the computer not seeing the WiFi router, depending on the situation, are the following:

  • wrong connection;
  • incorrect access parameters;
  • lack of network card drivers;
  • inoperability of the Wi-Fi module;
  • hidden network.

What if the computer does not see the router on a direct connection?

Let's start with a situation where a user tries to connect to a router for initial setup via a cable directly. It seems that all the cables are connected correctly, but still there is no connection. Well, the computer does not see the router, even if you crack. What should I do?

First of all, if you are sure that all cables are connected correctly, check if the address of the router itself is entered correctly in the web browser. In most cases, this is 192.168 with the last two digits 0.1 or 1.1 (for some non-standard models, other addresses may be used).

The entrance address can be found on a special plate located on the back of the device. There is also a username and password that must be entered when entering the settings.

If everything is entered correctly, but the router is not visible, it may be helpful to simply reboot the router by pressing the On / Off or Power buttons for 10-15 seconds. However, it is best to unplug the router completely from the mains, keeping the same interval. If, after that, the computer does not see the router, you can try to reset the router settings to the factory settings. To do this, there is a small hole in the bottom of the case, in which there is a barely noticeable Reset button.

Checking if the connection is correct

If the previous actions did not have an effect, you should check the correctness of the direct connection.

Try plugging the network cable into a different connector on the router, or similar actions on the computer's network card. If that doesn't work, the cause may be damage to the cable itself. In this case, just replace it and try again to enter the settings.

Connection Diagnostics and Ethernet Ports Test

Also, the situation when the computer does not see the Wi-Fi router may be due to the breakdown of the ports themselves. As already mentioned, use a different port or "ring" the one to which you are connecting.

However, the reason may also be in the network adapter. In this case, you should make sure that all the necessary drivers are installed for it in the system (and correctly). If the device is marked with a yellow exclamation mark in the appropriate manager, the drivers must be reinstalled. Also, as an option, you can use a complete removal of the device, followed by a reboot of the system, when the driver is installed automatically. In the case of non-standard equipment, you must use original discs or specify the location of the driver installation file on the hard disk manually.

To get more detailed information, you need to diagnose the connection. It is performed from the adapter parameters section, which is located in the network connections menu located in the standard "Control Panel". If problems are found, the system will inform you about their elimination.

Checking network attributes

Finally, the reason that the computer does not see the router when using a wireless connection may be set to hide the network in the settings.

In this situation, you need to connect to the router directly with a cable, enter the wireless settings and uncheck the box to enable SSID broadcasting (for TP-Link models). In other devices, this can be a point of hiding the network name, setting just hiding the network (SSID), or something else like that. After that, it is advisable to reboot the device using the method described above. In addition, it would be nice to restart the main computer system (as they say, you never know what).

Conclusion

In most cases, the above methods will help correct the connection situation. If none of these solutions helped, in order not to replace the equipment, you will need to rewrite the device. Doing it yourself at home is quite problematic, so it is best to contact some service center. If, however, such actions do not give a result, you will have to make a complete diagnosis of the router not the subject of faults, but if they are detected, replace the device.

But, as practice shows, most often there is an incorrect entry of addresses and parameters when entering the settings, breakage of cables and ports, the absence of drivers for network cards and wireless modules, as well as the set parameters for hiding networks. So at least one of the proposed methods will help.

At present, the controversial expression 10-15 years ago, “a computer is a network, a network is a computer,” is perceived as an axiom. The network connects computers and other devices at home and at work, and without the Internet, many can no longer imagine their lives. And if suddenly there is some kind of failure and access to the World Wide Web is terminated, this is perceived extremely negatively. It also happens that everything is fine with the equipment, but a laptop or computer running under Windows, for the life of me, does not see the Wi-Fi network. What may be the reasons for this problem and how to solve it, we will talk in this article.

Causes and solutions

So, suppose we are on a business trip, we receive a new laptop with Windows 8 installed upon arrival and try to connect to Wi-Fi, but the operating system cannot find the network. The list of available connections is empty. There may be several reasons for this, and they are divided into hardware and software. With the hardware, everything is quite simple - it is very likely that the WI-Fi adapter on the laptop has broken. It is impossible to replace it yourself, therefore, if there is no time to go to the service, you will have to connect to the network with a cable in the old fashioned way or use another computer. There may, of course, be problems with the router, but if the rest of the users have a wireless network working without complaints, and even your smartphone sees it perfectly, then it has nothing to do with it, and the point is in the laptop.

Among the software reasons that the computer does not find the network, there are several of the most probable ones:

  • You must use the wireless adapter on your laptop.
  • Wi-Fi controller is disabled in Windows.
  • Drivers are not installed or are not suitable.

1. BIOS.

In the first case, there is a chance that the wireless device is disabled through the BIOS. You can get there by pressing the F2, F10, Del key - the specific value also depends on the brand of the laptop. Next, we find a section whose name contains the word Configuration, Advanced, System devices or something like that, the main thing is that it contains information about built-in devices. We check if the value is Off or Disabled opposite the wireless adapter, designated as Wlan device, Wireless, Wi-Fi controller, and so on.
2. Power button on laptop.

If everything is fine in the BIOS, and the problem persists, pay attention to the laptop case, most often the wireless power button looks like a switch and is combined with an indicator:
3. Power buttons on the keyboard.

It may happen that there is no hardware button, but this does not create a problem either - you should examine the keyboard, among the function keys there is one that, when pressed together with the Fn key, turns on Wi-Fi. It is indicated by a special icon. Let's illustrate how it might look for different laptop manufacturers:
In the second case, if the Wi-Fi controller is disabled, you should check two different Windows 8 settings.

4. Turn on the Wi-Fi adapter.

The adapter itself can be turned off to check, go to "Control Panel" - "Network and Sharing Center" - "Change adapter settings" and, if we see that the wireless connection is gray, and its status is "Disabled", it remains simple turn it on.
5. Check if Wi-Fi is enabled in Windows 8 software.

You need to make sure Wi-Fi is not turned off in the right pop-up panel of Windows. Move the mouse cursor to the upper or lower right corner of the monitor and go to the "Wireless mode" section. We turn on the adapter, if it is disabled only for the "Airplane" mode, we check to see if it is currently being used. 6. Checking the Wi-Fi driver... Finally, if the previous options did not work, you will have to tinker with the driver. If the bundled with Windows 8 is installed, this may be the cause of the problem, it is always better to use the program from the manufacturer. Open the device manager by going to the "Control Panel" - "System" or by pressing Win + R on the keyboard and entering the text devmgmt.msc into the command line. Find the Wi-Fi controller (the name will contain the word "Wireless" or "Wi-Fi"). When the device icon looks like a yellow triangle with an exclamation mark, there is a problem with the driver and needs to be reinstalled.

If, at first glance, everything is fine, it is worth making sure that the correct software is installed for the adapter. By clicking on its name with the right mouse button, we will open the properties window, after which we will go to the Driver tab and see information about the supplier and the release date of the program. If Microsoft is listed there and two or three years have passed since the driver was released, you should definitely go to the official website of the laptop manufacturer, download and install the latest version. It is possible that another version of Windows was installed on the computer and the driver supplied with it is not suitable for this hardware.

The computer does not see the router - first of all, we look at the cable. You need a full-fledged patch cord. The twisted pairs of the crossover transceivers are crossed. It's hard to come across a wrong option today. However, there were times of influx of people who wanted to connect 2 PCs directly. The factor of the features of the Ethernet ports of a router and a computer appears here - they are mirrored ...

There were curious cases: ping passes, the PC does not see the network. Earlier versions of Microsoft operating systems (XP, 7) had to constantly reboot. Windows 10 is devoid of this flaw. By the way, open the command line, type ping 192.168.0.1 (the numbers indicate the IP address of the router, sometimes the values ​​are different: 192.168.1.1, 192.168.10.1 ...).

Perfect option

Try connecting another device. There was Asus, there was Zyxel. Locate the source of the problem quickly:

  1. Cord.
  2. Router.
  3. External reasons (hacker attack, hacking attempt).

Change cable

Change the cable immediately. The problem is in the wire. The vein is cut off, or the patch is incorrect, incomplete. They produce cables where only a part of the clamped pins is present. Early network protocols sometimes took shocking liberties. The system is fully functional, but backward compatibility is lost.

  1. Take a working cable.
  2. Make a connection.

Sees the network, but the address of the admin panel is not available? Two options:

  1. Someone changed the IP address of the router by setting up the equipment. Then the combination of numbers is also not available via Wi-Fi. Check the current IP address using wireless communication.
  2. A hacker attack is underway. Unplug the cord, reboot.

Reload equipment

Routers hang at times. Sometimes Wi-Fi works. The reason is the same. The Internet breeds hackers every day. Probably TP-Link, or a laptop via a cable were attacked. Even if functionality is restored, it is recommended to perform a hard reset of the device. Then check "doctor web smokes".

Antivirus

Before a hard reset, download an antivirus.

  • Open a search engine.
  • Type "Doctor Web Smokes".
  • Download the utility.
  • Disconnect the cable.
  • Run a check.
  • Destroy the found threats.

Let's consider a typical example. A user of the f1comp forum complains: a TP-Link router, a laptop works fine (including Wi-Fi, Ethernet), a connected PC gets an IP address like 169.154.x.x, refuses to recognize the hardware. A typical case of infection. Immediately download the antivirus in any way, perform a hard reset, heal, tune in again. The problem is compounded by the slow response of antivirus vendors. Fresh infection is practically invulnerable, take comfort in the example of Red October.

Hard reset

  • Examine the body of the router looking for a recessed miniature (2-4 mm diameter) button labeled Reset.
  • Take a ballpoint pen refill or paper clip.
  • Push the sting inside, holding the key down for 3-5 seconds.
  • Check the connection.

If the computer still does not detect the router, please complete the WAN settings via Wi-Fi. There is a high probability of a cable malfunction.

After performing a hard reset, re-configure the technique.

Failed update

An unusual case has been described by users of the forums. The admin panel asked to update the firmware. The user agreed. However, impatience let down. Tired of waiting, the user turned off the power.

After loading, it turned out: the wired interface is not available. Although the wifi regularly gives the panel. An excellent example of irrecoverable damage to equipment. Why irrevocable? Router manufacturers prohibit over-the-air updates. Since the cable has stopped working, further actions become mysteriously unpredictable.

It is interesting! Operating systems Windows often break, try the user to hurry up by turning off the power. Nonsense. The first PCs rebooted easily. Consider the gift from the router manufacturers as another exercise in patience.

Unlikely causes

In our memory, D-Link stubbornly refuses to break. Computers are also very reliable. However, there are authors who claim: the iron has broken!

  1. Network Card.
  2. Motherboard.
  3. Brain ... PC.

The likelihood is extremely low. Craftsmen, however, provide one more piece of advice ... check the drivers. The ability to surf the Internet while the Rostelecom router refuses to get in touch at the same time makes such arguments laughable. Recall the stubborn location of Device Manager:

  1. Win + R (run tool Run).

Select your Ethernet NIC, right click, select update drivers.

The most common laptop problems are setting up and connecting to Wi-Fi networks. Therefore, before proceeding with possible solutions to this particular problem, you first need to check whether the connection itself is configured properly or not.

What is the reason?

The problem can be, for example, in the router used by the user, or in the operating system itself. The most common reasons why Wi-Fi is not displayed or is not seen by a laptop may be due to the fact that: The Wi-Fi router is frozen or not configured, there may be various problems with the device that connects to Wi-Fi , Internet access is blocked by a firewall or antivirus, and DHCP does not provide an IP address.

Troubleshooting

To find out the cause and then fix the problem, you need to check the router. To do this, restart the router and see if the network is displayed in the list. If this has not happened yet, then it is necessary to disconnect the network cable from the router and rearrange it into the appropriate connector.

This will allow you to check if the Internet comes from the provider at all or not. If the Internet does not come, then the matter is directly with the service provider, otherwise, it will be required. To configure it, you need to go to the address 192.168.1.1, or 192.168.0.1, depending on the router model.

If everything is in order in the settings, then you need to update or install the drivers for the network adapter. You can easily find them on the Internet, but this will require you to find out the model. To do this, open the "Control Panel" and select "Device Manager" from the menu. In the list you need to find the item "Network adapters". Here you will see a list of all network devices working on the computer, and in order to find Wi-Fi, you should select the item where the phrase "Wireless device ..." is present. After searching and installing all drivers, Wi-Fi networks should be displayed.

In the event that none of these methods helped to eliminate the urgent problem, then most likely the problem lies directly with the device itself, which is trying to find and connect to the wireless network. To check this, you can purchase an inexpensive USB Wi-Fi adapter or take it from a friend and install it.
