When Wi-Fi does not work on a laptop, the problem can be solved in three to five clicks, read how! Not working wi-fi - this phenomenon is quite common, and most often occurs if any changes are made: after reinstalling the OS, updating firmware, replacing a router, and others. Sometimes it is difficult even for experienced craftsmen to find the cause of problems in the Internet.

What is the reason for Wi-Fi not working on laptop?

The reasons for the inability to connect to Wi-Fi can be very different, they can be conditionally divided into simple and complex. And in this article we will try to consider the main ones.

Banal (simple) reasons for not working Wi-Fi

1. You have not paid for the Internet - pay for it.
2. The router is not turned on - turn it on.
3. No Wi-Fi coverage - move closer to the router.
4. Your router is "buggy" - reboot it.

Serious reasons for not working Wi-Fi

If you have a problem connecting to Wi-Fi, then first you need to determine what the reason is: in a router or in a laptop.

The easiest way to find out what the problem is is to connect another device to your router or connect your laptop to a different Wi-Fi network.

Wi-Fi router/router not configured

Before connecting to a wireless network, you need to configure the router. If you have not done this, then you should find on the Internet instructions for the router of your model and for your particular provider.

To find out if the connection from the provider works, you need to check in the WAN tab in the admin panel or the indicator on the router. If the connection from the provider does not work, then the problem may be as follows:

• Incorrect connection settings to the provider are specified in the admin panel.
• The router is faulty.
• ISP problems. To exclude or confirm this option, you can contact the provider.

Wi-Fi does not work on a laptop - the receiver is not working (burned out)

Sometimes laptop wifi just stops working. The network connection is either missing or unstable. The reason may be a breakdown of the Wi-fi module in the laptop. Then it may need to be replaced or repaired.

The most likely reason for a laptop not connecting to the Internet after reinstalling the operating system is the inability of your new operating system to find and install a driver suitable for your network card.

As a rule, to install the driver on the network adapter, you must use the driver disk that came with the laptop, and you can also download correct driver from the manufacturer's website specific model your device.

You can check if the driver is installed on the network adapter in the Device Manager.

Wi-Fi module is not enabled in your laptop

There are 2 ways to enable the Wi-Fi adapter programmatically if it was previously disabled in the OS settings:

1. Through the Network and Sharing Center and public access. You need to enter the ncpa.cpl command in the input window after pressing the Win + R combination. This command will open "Change adapter settings", from there you need to go to "Wireless network connection". If the network adapter icon is gray, then you need to enable it.
2. Through the device manager. If the adapter is disabled in Device Manager, then the Wireless Network Connection icon will not appear in Network Connections. Then, as in point 1, you need to press Win + R. Then you need to enter the command devmgmt.msc, it will open the device manager. Next, we find a device that contains Wi-Fi or Wireless in its name, and after right-clicking, you need to click "Enable". If the adapter does not turn on, then you need to check if there are suitable drivers.

Firewall or antivirus blocking internet access

Sometimes your OS security features such as antivirus or firewall can prevent your laptop from connecting to Wi-Fi.

If the problem is in the firewall, then it is not difficult to solve the problem: you just need to disable it in the system settings.
If the antivirus arranges obstacles, then you must either complete the task through the task manager the right processes, or you can disable the antivirus itself.

Viruses and Malware block wifi

If you do not have an antivirus installed or it is outdated, then there is a high probability that you will encounter a virus - a blocker. Such viruses block your access to the Internet, allegedly due to breaking the law. Such a virus works very simply: it registers its DNS servers in the network settings, and your browser finds only a fraudulent site. To solve the problem, you just need to change the DNS servers to the ones that suit you.

There may be too many devices connected to your wi-fi. Look and turn off the most active ones who "clog" the Internet channel.

Many factors affect the speed of Wi-Fi. They are treated as external problems, and the matter may be in the device.

The most common reasons:

• A laptop network adapter and a Wi-Fi router have different capabilities.
• An unauthorized connection has occurred to your router.
• Influence of electrical appliances.
• Wrong router location.
• The wireless channel is being affected by another router.
• The equipment is outdated.

Advice: To make your Wi-Fi work faster, try rebooting your router, moving it to a different location, or updating its firmware.

If before reinstalling windows Wi-Fi on the laptop worked properly - then the reason can only be in the drivers. Right-click on the "My Computer" icon, go to the "Hardware" tab, then click on the "Device Manager" button. In the list that appears, icons with exclamation mark those devices for which the driver is not installed are indicated.

Find out your model motherboard(if you have desktop computer) or your laptop model (you can see it under the battery). Then go to the manufacturer's website and download the drivers for your network card. After installing them, Wi-Fi will reappear on your computer.

The wifi button does not work on a lenovo/HP/asus/acer laptop - how to fix it?

You can fix a non-working button only by replacing the entire laptop keyboard, order a keyboard from your laptop and replace the old one with a new one yourself or take your laptop to a service.

Important! While the button does not work, you can turn on wi-fi on your laptop without a button, using OS Windows. To do this, click: "Start" - "Control Panel" - "Network and Internet" - "Network and Sharing Center". On the left, click on the item: "Change adapter settings." Next, we are looking for a wireless network, right-click on it and select the item - ENABLE.

What to do if the wifi driver does not work on a laptop?

In this state of affairs, we have no options, we either need to update old driver, or remove the existing driver and install a new one.

To remove the current driver from your Wi-Fi - right-click on the "My Computer" icon, go to the "Hardware" tab, then click on the "Device Manager" button. Next in the list, we look for your network card and remove all network equipment, then restart the computer and install new driver for wifi.

There are also cases when your wi-fi adapter (network card) does not have new drivers for modern operating systems, in which case you need to return the old one operating system.

One of the most common problems on mobile gadgets with the Android platform is the lack of access to the Internet. We will talk about why the wireless, Wi-Fi, network does not connect or is unstable. If there is no Wi-Fi connection on your tablet, smartphone or phone, first of all, you need to find the cause of incorrect operation, and only then look for ways to fix errors. We will list several types of problems, and you will find your own among them, and depending on this, use this or that recommendation or instruction.

Wrong date and time

This is not a common mistake, but it's still worth checking. What if the problem is that your mobile gadget shows the wrong time and date? To check, open the "Settings" of the smartphone / tablet and look at the "Date and time". If the settings are incorrect, change them.

Wrong password entered

Perhaps you changed the network password, but "forgot to tell" your "smart" computer about it? This problem, unlike the first, on the contrary, is quite common. Go to Settings wireless connection and delete the "old" profile from which you are trying to connect to the network. Now try to reconnect to the network.

Software failures

This reason, due to which Wi-Fi does not connect, is also common. Unstable operation of the software is detected simply: for this, you need to download and install the software on the device. We recommend using for these purposes. This is a small application specially designed to solve problems with unstable internet on mobile devices. Neither your settings nor your content will be affected.

After starting the utility, the main window will open, where you can see the status of the Internet connection. And the “Known” tab contains information about all connections.

All you need to do is restart your smartphone and connect again via Wi-Fi.

Crash in settings

Lost user settings is another common problem. And there is only one solution here, and not the most pleasant one: resetting the parameters to the original ones (from the manufacturer). To restore factory settings, open "Settings" and go to the appropriate item. With it, you can reset the parameters and restore their original values.

Click on the "Reset settings" button.

Installing the wrong firmware

If there is a problem connecting the device to the network via wireless technology arose after the firmware, then you used the unofficial version. This was the cause of unstable or incorrect work. And the only solution is to reflash the device, returning it to the factory software.

Viruses

And this problem often, alas, occurs. Perhaps, with the help of one of the applications, viruses got onto the mobile device. There are various programs that scan the operating system and remove malicious codes. Be sure to check your smartphone/tablet.

Wrong router settings

Incorrect set parameters router is a common cause of a Wi-Fi connection not working. To configure the router correctly, you need to do everything as in the instructions. If you didn't throw away the box from under the router, find the paperwork and set everything up properly.

Open the Device Management Menu and select "Settings wireless mode". You must change the parameters of two lines. "Channel" - set the parameter "auto", "Mode" - the parameter "11 bgn mixed". Go to the "MAC Address Filtering" tab and change the setting to "disabled".

conclusions

If the cause is not identified and not resolved, most likely one of the radio modules is faulty. The correct decision is not to engage in "self-treatment", but to take it to repair (service center or workshop). If you do not have sufficient technical knowledge, it is better not to take risks, after all, so as not to buy a new gadget.

Routers and access points with Wi-Fi are an essential attribute of the home and mobile internet it's been 10 years now. Once the speed of the Wi-Fi network can be greatly reduced, and sometimes the wireless connection disappears completely and for a long time.

The main reasons for the disruption of the Wi-Fi network

Problems with wireless Internet access can be associated with various reasons: router failures, incorrect settings of a computer or smartphone, interference from nearby equipment, etc. Viruses and even hacker actions can disrupt the operation. In all cases, you need to identify the cause of the malfunction and try to fix it - first yourself, and if it does not work, then contacting professional computer specialists.

Wi-Fi network is visible to devices, but they do not connect to it

There are several reasons why there may be no connection to a Wi-Fi network.

Wi-Fi network is not visible to devices

There are several reasons why the Wi-Fi network is not visible from a gadget or PC.

Wi-Fi not working on PC or tablet after reinstalling Windows

There are several reasons - from hardware to software.

Video: WI-Fi does not work after updating Windows 10

The laptop or tablet is connected to Wi-Fi, but there is no Internet

The reasons are due to the fact that the router does not have access to the Internet.

There is Internet via Wi-Fi, but it turns off by itself

There can also be several reasons.

1. The quality of the Internet connection is inadequate. If the provider has an unreliable communication channel or, in the battle for the first place in the list of the most popular operators, it went too far with the number of clients, the speed of individual users will be very low, the connection will often reconnect due to equipment overload, and incoming traffic- hang out. Previously, cellular providers suffered from this - at the initial stages of the development of a 2G / 3G / 4G coverage area, demand, in the face of a collapse in the price of 1 MB of traffic, far outstripped the construction and launch of new network facilities.
2. hangup random access memory router (data buffer overload). Restarting it will help.
3. The device has overheated - any modern technology has protection against overheating of microcircuits. Both the CPU / RAM of the router or access point, as well as any of its microcontrollers processing incoming / outgoing data via LAN or Wi-Fi, can overheat. It is advisable to turn off the router for at least a few minutes.

When bad signal 3G/4G and high speed Internet, the 4G modem used with the router can also overheat at the same time. Users of Android smartphones and tablets (Yota subscribers), who distributed up to 40 GB every day via Wi-Fi (in the 2000s, these were Nokia and Motorola mobile phones connected by cable or Bluetooth), talk about cases when the device heated up like a kettle and disconnected every hour or two of downloading / distributing torrents on a PC. The same thing happens with routers.

Wi-Fi not working due to firmware glitches and viruses

No matter how simple, friendly and secure the firmware (firmware) of the router is, the router itself is not protected from malfunctions and viruses. Virus technologies disrupted Apple, Android and Symbian gadgets. The virus code penetrated into kart machines, ATMs and access control systems at guarded facilities with the Internet, disabled the firmware in USB modems. Routers are also not insured - neither purely wireless from Beeline or Yota, nor home ZyXEL and TP-Link, nor Cisco access points, nor purely cable equipment used at sites where any wireless element is prohibited by security rules.

Failures in the software can occur both due to inept flashing (unknowingly or accidentally, power is reset at the time of firmware update in the flash memory of the router), and wear and tear of the flash memory chip itself (it is even impossible to enter the router settings - underloading of web pages interface in the browser).

Viral activity is expressed in the reprogramming of the router settings: changing the IP DNS to the values ​​of the malware server, substituting primitive passwords or disabling Wi-Fi security settings, switching wired protocols and the mode of operation of cellular networks, etc. To fix this, do the following.

Sometimes the virus changes the firmware file just before loading it into the router. The solution is to remove viruses from the PC, using all means up to formatting the drive (of course, transferring valuable data to other media before that) and download official version firmware again from the manufacturer's website.

Slow internet speed over Wi-Fi

The reasons are related to both the quality of network access and the parameters of Wi-Fi communication.

1. Low speed cable or cellular data provider. If the speed of Rostelecom and its dealers is not limited, then in cellular networks, for example, in MegaFon or MTS, after a certain number of gigabytes of traffic per month, the speed drops to 64 (or 128) kbps. Change your tariff and provider.

   MTS limits the connection speed on the Hype tariff after the subscriber has used up 7 GB mobile traffic per month

2. Unstable operation of LAN-Ethernet 10/100 networks. You can feel how the speed has dropped sharply due to the damaged cable of the provider coming from the optical terminal at the entrance to the apartment, watching a movie in (Ultra) HD-format online: movie playback, yesterday is still stable, “slows down” every second loading data. Several years ago, the provider itself was to blame, but now the speed of the same Rostelecom subscribers has grown so much that 95% of the time it will be normal, excluding the evening hours when the load is at its maximum. With constant "brakes" online video with 100% certainty, you can suspect a malfunction of either the cable or the router itself.

   If the cable or router malfunctions, the connection speed drops sharply

3. Overloading the data buffer of the router. Restart it.
4. You have moved too far from the device. In fact, the Wi-Fi speed, depending on the distance between the router and the gadget / PC, as well as on the level of the Wi-Fi signal on the gadget itself, fluctuates hundreds of times - from 1 to 300 Mbps, this is how wifi technology. If in one room the speed is 150-300 Mbit / s, then in the next room it can already be from 11 to 54 Mbit / s, and in the entrance or on the street - it can drop to 1 Mbit / s. Wi-Fi interruptions will not affect the cable connection (LAN cable length up to 250 m).

   Choose autoswitching speed using Wi-Fi technology

The last point requires clarification. The fact is that the Wi-Fi speed is switched automatically by the router and the gadget. Even if you forcibly turn on the maximum (802.11n or 150 Mbps), then going to the next room, you can lose the connection to the Internet - incoming and outgoing traffic "freezes", sites stop opening and messengers work, even simple ones like ICQ , since a lower-level speed (802.11g, or 54 Mbps) will not be enabled.

Different wifi types networks support different speed data transmission

Check the auto speed selection in the router settings.

Experimental tip: Without highly directional antennas and amplifiers, do not position yourself far from the router.

Other Wi-Fi errors and solutions

A complete list of errors in Wi-Fi operation is not limited to failures of a single Wi-Fi repeater or problems on the provider's side.

Network cable not connected

The provider's network cable connected to the WAN socket may not be connected either to the router itself or in the entrance terminal. The reasons are as follows:

• damaged cable wires;
• Broken RJ-45 connector retainer holding the cable in the LAN socket
• disconnected electricity (the terminal does not have an autonomous power supply);
• malfunction of the LAN interface in the terminal and / or in the router (burnout of network equipment throughout the entire area from electrical interference, an accidentally thrown network wire, static discharge when materials are touched or a lightning strike into external cables);
• faulty LAN network card in a PC or laptop (it happens that the adapter in Windows is defined as a working device, but it is impossible to identify the connection);
• viruses on PC that overloaded Windows performance(displaying an incorrect connection status or connecting with a delay of minutes and hours).

The connection is already in use or not configured

Error 651 reports that the modem or dedicated one is already in use or has not been configured.

If the router is not configured or is already in use by other processes, error 651 is issued

Removal and reconfiguration of your connection is required. The instruction is suitable for Windows 7/8/10 - the work with the network connection setup wizard in the latest versions has not been enriched with anything special.

1. Give the command "Start - Control Panel - Network and Sharing Center".

   Network Settings Center is ready to go (Windows 7/8/10)

2. Select to create a new network connection.

   To create a new connection, select the network connection option

3. Choose to create a high-speed connection.

   At the step of choosing the connection type, set the work over the PPPoE protocol

4. Enter the connection name, login, password, mark remembering the password. It is advisable to enable the use of this connection by other users (if the problem is common for everyone).

After clicking the "Connect" button, the Internet connection will be established. If the problem persists, contact the provider's support. In the worst case, reinstalling Windows helps.

Endless receipt of an IP address from a router

Without getting at least a temporary IP address from the DHCP numbering range of the router's IP addresses, the gadget or PC will not be able to access the network. And this is not only typical of Wi-Fi connections - assigning an IP to a computer or mobile device laid down during the creation of TCP / IP.

If the device "hangs" at the stage of obtaining an IP address, you need to check the settings of the router

It is required to check the IP settings of the router.

Checking Wi-Fi Settings

Please do the following.

1. Restart your router.

   To keep the power adapter from being pulled out of the outlet, press the power button twice

2. Give the command "DHCP - DHCP settings", check if the DHCP function is enabled and what address range is assigned to third-party devices.

   Make sure WPA2 / TKIP encryption is enabled and a key you know is assigned

3. Go to the item "Filtering by MAC addresses" and check that the MAC address filter settings are disabled, and the option "Allow the stations specified by any enabled entries in he list to access) - installed.

   MAC address filtering is often confusing when Wi-Fi security requirements are less stringent

4. Save the settings by clicking the "Save" button on each of the pages, and try to reconnect.

The router may need to be restarted again.

Checking services and connections in Windows

Make sure all network critical services, addresses, and protocols are in use correctly. For network Windows features the following services are responsible:

• DHCP client;
• DNS client;
• WLAN autoconfiguration service;
• web client;
• ancillary IP service;
• routing and remote access;
• server.

Please do the following.

The router or cable modem is not connected to the network

ADSL modems, popular in the 2000s, are being actively replaced by ONT modems (network optical terminal) - these devices support Internet speeds up to 1 Gbps (using GPON technology), which is different from bandwidth ADSL modem 10 times. Already now, Rostelecom and local providers provide Internet speeds of the order of 35-100 Mbit / s.

The reason for the decrease in Wi-Fi speed can be not only an underestimated external speed on the cheapest of available rates, but also damage to optical cables in the section ONT-modem - home rack-terminal - the nearest provider node. The LAN cable between the router and ONT modem may also be damaged.

The router in access point mode acts as a LAN / Wi-Fi distributor

Diagnostics of the entire subnet of the router (the router itself and its external cable) the user can conduct himself. In case of damage to cables and equipment, including ONT-modem, telephone, IPTV set-top box and cables at the entrance, you should use the help of technical specialists of the same Rostelecom. This is also due to the fact that if twisted pair can be repaired/replaced on their own, then the subscriber simply may not have the tools for splicing damaged FOCLs.

Solving problems with WiFi at home and at work does not cause much difficulty. In many cases, the user will figure it out on his own. The help of a specialist is required only in cases where problems arise on the side of the provider.

Hello, Dear friends. As you probably already understood from the title, today I decided to touch on a very serious and painful topic, and try to figure out what to do when Wi-Fi does not work on a laptop or netbook and how to connect a laptop to a Wi-Fi router. By the way, it can be not only a laptop, or a netbook, it can also be an ordinary stationary computer with Wi-Fi receiver. There have been a lot of similar questions lately, mainly to the article.

Now we will try to figure out step by step what and why problems may appear when connecting a laptop to wireless wifi networks. We will also try to find a solution to this very popular and unpleasant problem with connecting to Wi-Fi, or rather an unsuccessful connection.

Most often, problems arise when you cannot turn on the Wi-Fi module itself on a laptop. And when Wi-Fi turns on, the laptop finds all available networks, but when you try to connect, it writes. You need to check if the drivers are installed on Wi-Fi adapter whether Wi-Fi is enabled on the laptop, etc. Now we will deal with this.

I noticed that most often problems with connecting to Wi-Fi are found in Windows 7. It is on this OS that the error network without access to the Internet very often appears, I wrote how to solve this problem in the article, the link to which is above. In fact, as practice shows, there can be a lot of reasons for this problem. And if there are many reasons, then there are many ways in which you can make a laptop connect to a Wi-Fi router.

But it is not always the laptop, netbook, etc. that is to blame. There may be a problem in the access point, that is, in the Wi-Fi router. And the first thing we need to do when there is a problem with connecting to Wi-Fi is to determine what is the reason, in a laptop, or in a Wi-Fi router. Now I will consider the problem with connecting to my own router. Because if you are unable to establish a connection with someone else's Wi-Fi, then all claims are against the neighbor, it is most likely that he has problems :).

Who is to blame, laptop or Wi-Fi router?

As I wrote above, you first need to find the culprit. Before you make any settings on a laptop or Wi-Fi router, you need to understand what the problem is, which is why you can’t connect your laptop to Wi-Fi. You can just set it up so that you then have to do it and set everything up again. Most The best way to determine in which device the problem is hiding, it is to try to connect another device to the router, for example, another laptop, tablet, or phone. And a laptop that has problems connecting to Wi-Fi, you need to try connecting to a different wireless network.

I think that you understood my idea. If there are other devices connected to your router (best with similar operating system) will connect without problems, then the problem is in the laptop. Read this article further, now we will try to solve it.

Well, if problems when connecting to your network occur on other devices, and the “problem” laptop connects to other networks without problems, then the problem is in the configuration WiFi router. See the article on, it might come in handy.

I will show on the example of a laptop that runs on Windows 7. This is currently the most popular operating system.

I advise you to immediately pay attention to the icon that displays the status of the Internet connection. It's in the notification bar.

If the internet connection status looks like this:

First you need to check if the Wi-Fi drivers are installed and if the Wi-Fi adapter is enabled.

Right click on "My computer" and select "Properties". Left select "Device Manager".

Open a tab in a new window “Network adapters” and see if there is a device like Wireless Network Adapter (Your name may be different). If you have such a device, then right-click on it and select "Properties". Another window will open, make sure it says "The device is working properly."

If everything is about the same as mine above in the screenshot, then everything is fine, the driver is installed. And if there is no Wireless Network Adapter device and you have unidentified devices, go to the website of your laptop manufacturer, download and install the Wireless Network Adapter driver for your model.

Learn more about installing and updating the driver for wireless adapter – .

Dealt with the drivers.

Checking if Wi-Fi is enabled on the laptop

If the driver is installed, but the Wi-Fi module is disabled, then the connection status will be the same:

Usually the wireless network adapter on the laptop is turned on, but it doesn't hurt to check. Wi-Fi on laptops (netbooks) is usually turned on and off with a keyboard shortcut. On my ASUS K56cm, these are the keys FN+F2. But although when I press these keys, I get a message that wireless adapters are enabled / disabled, but nothing happens. Look for a key on your laptop FN and key with a picture of a wireless network. Press them at the same time.

On some laptops, there may be a special switch on the case that you can turn Wi-Fi on or off. For example on Toshiba Satellite L300 it looks like this:

Enable or disable the wireless Wi-Fi adapter in Windows 7

But the best way to check if the wireless network adapter is working or not is to go to the network control center and see.

So on the notification panel, right-click on the Internet connection status icon and select "Network and Sharing Center".

Then select on the left.

Looking for connections “Wireless Network Connection”. If everything is fine and the Wi-Fi adapter is enabled, then it should look like this:

If the adapter is disabled, it will look like the screenshot below. Click on it with the right mouse button and select "Enable".

Using the methods described above, we must make sure that the status of the Internet connection on the notification panel is like this:

This status means “No connection - Yes available connections” - this means that the Wi-Fi adapter is turned on and there are available wireless networks for connection.

If the connection status is like this:

This means that Wi-Fi is on, but the laptop simply does not see networks available for connection.

Error “Windows could not connect to…”

We figured out the problem when the wireless network module is disabled, or does not work at all. Now consider the case where the laptop finds available wifi network, but when I try to connect to Wi-Fi, it says: “Windows could not connect to…”, where instead of dots is the name of the network you want to connect to.

If you have a network connection status such as in the screenshot above (via one, network with yellow icon), then click on it, and you will see a list of networks available for connection.

Select the desired network, click on it, then click the "Connect" button.

If the set is password protected, then Windows will ask you for a password. Enter the password for the network and click "OK".

And if everything is fine, then your laptop should connect to the Internet via a wireless connection. And the Internet connection status should look like this:

But it is at the moment of connection that the error "Windows could not connect to ..." very often appears. It looks like this:

Unfortunately, friends, there is no definite solution to this problem. But I can download that very often the problem with such an error appears due to WiFi settings router. Maybe through the type of security and encryption that is installed on the Wi-Fi router, read more about this in the article. There may also be a problem with the distribution of IP addresses.

If you notice, then in the window with the error "Windows could not connect to ..." it is possible to run “Troubleshooting”, sin not to use. Try to run it, I heard somewhere that there are cases in which it helps :). But seriously, sometimes it really helps. Windows will check if the wireless adapter is ready, check settings, etc. And if it can, it will fix the problem that is preventing you from connecting to Wi-Fi.

Just reboot the router and then the laptop. Very often this helps.

Update

I noticed that in Windows this error appears when the settings that are saved on the computer for your network do not match the current network settings. I'll explain now.

For example, your laptop was connected to Wi-Fi, it automatically connected to the network. But you took and changed the password, or the type of network encryption. Now the laptop is trying to connect to the network, but the parameters no longer match, that's the error.

It is enough just to delete the network on the computer and re-establish the connection. I wrote about it in an article

Conclusion

Great article turned out, and I hope that it is useful. I wrote it for half a day, intermittently, of course, there were still problems with adding screenshots to the site, but I sort of solved it.

I tried to collect all the necessary information that should help you solve the problem that occurs when connecting a laptop or netbook to Wi-Fi. If I forgot to write something, then in the future I will definitely supplement the article, I will also be very grateful if you share information in the comments that helped you solve the problem with connecting to a wireless network.

If you have any questions, then ask them in the comments, we will try to figure it out. Best wishes!
