Why the laptop does not see the wi fi router. Why can't I see the network? Wifi connection in windows xp via laptop

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

A bit about Wi-Fi coverage

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

• You don't need a cable to connect to your phone, laptop or tablet. Thus, the amount of cash costs is reduced.
• The owner of a phone, tablet or any other portable device is not restricted to a specific location. The use of the Internet can be anywhere the user wants.
• Wi-Fi coverage can be easily used 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

There is no need to mention such a reason as too much remoteness of the portable device from the connection point, that is, the router. The main thing is to keep 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 Wi-Fi connection on / off button. Therefore, it is worth checking that the connection is simply turned on. In newer models, you can use a keyboard shortcut such as Fn and F2 to enable Wi-Fi access. The documentation of the device will provide additional help.

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

• Theoretically, the reason may be a breakdown of the Wi-Fi module in a laptop or some other device. Moreover, if the guarantee is still valid, you can easily change the purchased product. If you have an old device, repairs can be very expensive. Therefore, many advise to purchase an external Wi-Fi adapter, which is quite affordable at a price.

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

Why can't my laptop see Wi-Fi? Access points are almost everywhere. But there is no way to connect to the Internet. Because the laptop seems to have gone blind. Everything seems to be done correctly.

The necessary settings have been made. And the computer is deaf. Why?

Laptop Won't Detect Wireless Internet: Why?

Many faced a similar problem. The most annoying thing is that a failure could happen at any site, any link. Popular routers that people use to connect today are configured in about the same way. From the side of the laptop, certain actions are also required, which are almost completely identical for all models.

Reasons for not detecting wireless networks:

1) Your router is not configured to receive a signal, it is turned off for some reason, started to glitch or freeze;

2) The reason lies in the computer; the appropriate settings have not been made, the hardware slider or the wireless connection button is disabled (it is usually located on the case);

3) The Internet has not been paid for or the provider has turned it off for other reasons;

4) The owner of the access point to which you are trying to connect unauthorized (without permission) is blocking your connection;

5) Antivirus program blocks the World Wide Web;

6) The IP address was not entered automatically.

There are many reasons. We will not explain situations when the provider restricts your actions or you are trying to connect to someone else's. In such cases, issues need to be resolved with money or personal charm. And here all the instructions are useless.

Finding a solution

Why can't the computer see the USB flash drive? The reason may be in the computer or in the flash drive. It's the same with wireless Internet.

To solve a problem, you need to classify it. Where did the link fail?

1. The router does not receive the signal, does not allow it to the Internet.
2. The laptop does not connect to the signal transmission device.
3. The signal is on, the computer sees the network, but it is still impossible to enter the Internet. For some reason.

Problem # 1. The router is not working.

The easiest way to make sure it works is to connect the laptop to it via a network cable. If everything is fine with the router, the internet connection will happen.

External signs of device inoperability:

a) the corresponding indicator on the case is "silent";
b) there is no Internet connection in the administrative panel in the WAN tab.

What can be done?

1. Turn off and then turn on the router (suddenly it freezes).
2. Check if the router and network card are turned on.
3. Check the settings for connecting to the provider. If necessary, re-enter them manually.
4. Call the provider and ask if everything is ok with the network.

Problem # 2. The laptop does not connect to the router.

The device receiving the signal is working. Other computers, smartphones, phones, and the like see the router. And a specific computer doesn't see anything.

1. Check the network connection on your computer (in the "Network Connections" tab).

2. We check the settings of the router and laptop. Through the "Control Panel" we find the network interface responsible for the connection. The path to it is different in different versions of the operating system. But usually the adapter is signed as "Wireless Network Connection". Go to "Properties" and find the protocol of the Internet version. We go back to "Properties" and check if the IP address, default gateway, subnet mask are specified. Perhaps this data was not entered at all. Then we enter them (they are obtained from the router).

3. We check on the device case whether the corresponding button is turned on.

Problem number 3. The laptop sees networks, but the Internet is not working.

1. We reinstall the Wi-Fi transmitter drivers (they are on the laptop manufacturer's website).

2. We check the presence of auto-switch to "Sleep mode". This setting often gets in the way. Therefore, the automatic transition to sleep mode must be disabled.

3. Make Wi-Fi a secure network for your computer. Perhaps the firewall perceives it as a threat and therefore does not allow it. The procedure can be performed through the "Network and Sharing Center". We go there and just select the desired network.

Try disabling your antivirus software while checking. Perhaps the problem is her. Any of these methods should help.

The situation when the laptop does not see the wifi network is quite common. Any user can face this problem. But to fix the problem, not everyone can do it. Therefore, we decided in this article to tell in detail why the laptop does not see the Wi-Fi network. Let's touch on the main reasons and, of course, how to eliminate them.

The first reason. Checking the router

First you need to check if everything is in order with the router. The easiest way to make sure the router is working is with a tablet, smartphone, netbook. Turn on and scan the radio, you will see a list of networks available for connection. Find the network you need, try to connect. If the gadget connects without any problems, then everything is in order with the router. And if the gadget will not see your Wi-Fi network, then there is a problem with the router.

Let's take a look at simple troubleshooting steps that anyone can do:

There is an “ON / OFF” or “On / Off” button on the back of the device, you just need to press it. On the front panel, the LEDs will all turn off, and then press this button again, the LEDs will turn on again. It is also possible to simply pull out the power supply from the 220V socket and insert it back after 5 seconds.

Lost settings

Due to a voltage drop (as well as a number of other reasons), the settings could fly off. In this case, you will see your WiFi network under a different name. These will be the default settings. Ideally, we recommend that you reset the settings again before configuring. To do this, take a match and press the "Reset" button, hold it down for 15-20 seconds. Now you can safely start entering parameters on the router. If you do not know how to do this, then on our website find an article with a full description of how to connect and configure a Wi-Fi router.

Changing the Wi-Fi broadcast channel

It happens that a laptop sees a bunch of unfamiliar wireless networks, but does not see its own network. Most often, this problem occurs on gadgets (smartphone, tablet). What's the catch, you ask? There are several reasons for this:

• Perhaps the neighbors, at the or the router, set the broadcast channel the same as yours. Their signal is stronger, so it clogs your signal.
• Modern routers can operate at 5 GHz, but laptops often do not know how to work at these frequencies. Therefore, when choosing a frequency, make sure your device supports that frequency.
• There is a 14th channel in the wi-fi that you could forcefully set on the router. Or you have the “Auto” mode in the “Channel” item. As a result, many devices will not see and connect. Keep in mind that not all gadgets can work in 14 (2.484 GHz) channel.

To fix the situation, go to the router settings menu and change the channel:

1. We launch the browser, register the IP address of the router in the command line.
2. In the settings menu we find the section "Wireless", then click on "Wireless Setting".
3. The "Channel" column displays the current broadcasting channel, change to any other.

Weather conditions

Don't have wi-fi after a thunderstorm? It is not surprising, because after such weather conditions, routers are brought en masse to service centers. Not everyone knows that Wi Fi routers are very afraid of thunderstorms. After such a bad weather, it often happens that the router is working, everything is glowing, but there is no Wi-Fi, the reason for this: the Wi-Fi module has burned out. Therefore, we recommend that in case of a strong thunderstorm, disconnect the power supply, pull out all network cables (twisted pair) from the back of the sockets. Just pull it out carefully, you do not need to jerk too much, otherwise you will tear off the RG 45 plug. Then you will have to read our article,

The second reason. Laptop problem

After making sure that the router is in good order, we continue to find out why your computer does not see the Wi-Fi. Now we will calculate the malfunction on the PC. Of course, we will not disassemble the laptop and check the WiFi adapter, but we will provide simple troubleshooting methods that any user can perform.

Wi-Fi module inactive

Checking the availability of drivers on the WiFi adapter

There is a chance that your laptop does not see Wi-Fi due to the lack of drivers. This can happen for a variety of reasons. For example, your PC got infected with a virus, accidentally deleted the wrong folder, turned off the computer incorrectly, or simply flew off. Therefore, it is necessary to check.

• We find "Search in Windows", either in the start-up, or on the desktop, click.
• We write “ device Manager". A window will pop up in which you need to open " Network adapters».
• We have this " Realtek 8821AE Wireless LAN….". You may have a slightly different name. We see that there is no exclamation mark yellow, which means that the drivers are all right. If there is an exclamation mark, it means that there is a problem with the drivers.

• Your task is to download fresh drivers from the official website of the laptop manufacturer and install them.

Check if the WLAN auto-configuration service is running or not

You need to check whether the WLAN autoconfiguration service is enabled or disabled. Without this service running, all adapters will be unavailable. Well, and accordingly the computer will not see the Wi-Fi network.

• We register the words "Services" in the search bar in Windows.
• We find " WLAN autoconfiguration service», Hover the cursor over this service, right-click. If it works, then there is nothing unnecessary to do, if disabled then select "Run".

We carry out troubleshooting

The diagnostic option doesn't help often, but it's worth a try. Click on the WiFi icon, which is located in the tray (there is a time next to it). Several options will pop up, select " Troubleshooting". The check will take a couple of minutes, and at the end Windows will display options for solving the problem.

The problem with the wi-fi adapter

Not sure why the laptop can't see the wi fi network? Try to remember how old he is. Perhaps he is already 10 years old, then it is not surprising, any device has a lifespan. You are unlikely to be able to disassemble the laptop and check the Wi-Fi adapter. It is better to contact the service center, they will carry out a full diagnosis there. Then you will hear the verdict.

Signs of problems in which you need to seek help from specialists:

1. The module works, but there is no Wi-Fi connection and does not respond to commands.
2. The adapter stopped memorizing the entered settings. Because of this, the laptop sees but does not connect.
3. The adapter is missing in the task manager.
4. Began to connect only at a distance of no more than one meter.
5. Periodically disappears, or wifi disappeared on the laptop completely and the reboot does not help.

Conclusion

After reading to the end, we hope you understand why the laptop does not see Wi-Fi. In the article, you will find a suitable way to solve this problem. Do not forget that first of all it is better to double-check the router, and then dig into the laptop. Because most often the problems occur in the routers.

A router (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 go to the router settings page, you need to perform a number of operations with the router and PC.

Most often, the 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 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 be off. 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 back on 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 opened window, 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 your network status and troubleshoot problems by reporting troubleshooting or identified issues.

Step 4. Re-connect 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 is from the provider side.

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 take a 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 the 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 need to 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 "ping 192.168.1.1" in the opened window 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 repair.

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 OK.

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".

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 which 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. On the right, in the drop-down list, 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. In the line "PSK Password" enter the password for the Wi-Fi connection. 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 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 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.

Video - Why the Internet does not work on the computer

In the operation of a wireless network, problems may arise when the computer either does not see Wi-Fi at all, or only the access point of a particular user is missing in the list of the nearest available networks. There may be several reasons for this, and they are eliminated in various ways.

Initial actions

First of all, you should restart the router or computer on which the connection has disappeared. You need to make sure that the password is entered correctly and that “Caps Lock” is disabled. If the code word is entered correctly, but the computer cannot connect, then the malfunction is caused by other reasons.

If no access points are visible on the computer, then you need to make sure the wireless adapter is active. To do this, the combination Fn + F3 is typed from the keyboard (different models may have different combinations of Fn + F2 or Fn + F5). For effective operation of key combinations, you need to take care of installing drivers on the keyboard. Older models may have a dedicated button for Wi-Fi detection.

Further actions

If there is no network connection after the above manipulations, you need to determine the specific cause of the problem. Wi-Fi connection may be lost after a long active state or due to some manipulation of computer equipment. When a malfunction occurs from the operating system, error signals are generated in the form of information that the Internet adapter is inactive.

To connect to Wi-Fi, you need to determine the root cause of the problem that caused the disappearance of the Internet connection and take action to fix it.

Difficulties in the network

If there is no Internet even if there are installed drivers for the keyboard and the Wi-Fi module is on, you should follow these steps:

1. Open “Control Panel”.
2. Go to the item "Internet networks".
3. Click “Network and Sharing Center” and on the left select “Change adapter settings”. All adapters will be listed there.
4. Go to the item “Wireless network”. If there is a gray icon with the inscription "Disabled", then there is no Wi-Fi sign in the system tray, so no action takes place. It should be put into the enabled state (right-click to go to the context menu and select “Enable”). The Wi-Fi connection will become active.

In case of an error, using the launch “Windows Networks Diagnostics” can help (right-click on “Wireless Network” and select “Diagnostics”). Correction of errors in this case will be performed by the system itself automatically.

Router problem

If the problem is that specific, then the following actions will be required:

Software problem

When Windows System Restore is enabled, the log will contain restore points for system rollback. You can return the operating system to a date with a working network and detected connections. Make your choice of state, click Next and follow the instructions on your computer screen.

Wi-Fi disappears while updating the operating system. For this reason, after the received updates, the program is reinstalled (including for wireless communication). After that, the computer will be able to see everything it needs.

Defective adapter

If all the tried methods did not help, and the PC does not detect the Wi-Fi network, then the wireless adapter may fail. It can burn out during operation, as it needs good cooling. The burned-out device is not displayed in the “Device Manager”, this problem will be displayed by “Windows Diagnostics”. Repair or replacement of the adapter will be required.

To remove the adapter, follow these steps:

If the adapter properties contain the "Enable" item, then it must be activated. After that, information about the absence of Wi-Fi in the network connection will not appear. In this case, you do not need to remove and restore the device.

Correcting the problem with the WLAN autoconfiguration service

The automatic settings service determines the order of actions in the settings, regulation and operation of local networks. With the help of this service, a virtual wireless access point is created, after which the computer is used as a router. The functioning of computer equipment can occur without turning on the WLAN function, while there will be no distribution of Wi-Fi.

WLAN is started using two methods:

Other troubleshooting methods

If Wi-Fi was in working condition before the problem appeared, troubleshooting will require:

• disconnect the router for 20 seconds with further equipment connection;
• eliminate problems with the Internet connection by clicking on the crossed-out Wi-Fi icon (if the cause of the breakdown is Windows);
• check if the wireless network connection is enabled in the subsection “Changing the adapter setting” from the “Network and Sharing Center” section in the “Control Panel”;
• turn on the hardware Wi-Fi switch in the computer equipment if it is in the off state (the switching process can be carried out with a certain combination of buttons).

Of the listed troubleshooting methods, when the computer does not see the Wi-Fi, the user will certainly be able to choose the most suitable one. You may have to try several methods before the problem is resolved. In any case, each method has a simple algorithm, accessible even to beginners and not capable of harming a computer.
