The netbook finds the network but does not connect. The network disappears when exiting sleep mode. The IP address is constantly being obtained

First of all, it is worth checking what exactly is the problem in this case. Connect to Wi-Fi through another device. If everything is in order, move on to the next steps.

Drivers are faulty

Drivers are most often to blame for Wi-Fi not working on a laptop. To check this, right-click on “ My computer" or " Computer", depending on the version of Windows, and go to the "Management" section or to "Properties". Then go to the “” tab.

Select Computer Management or Properties

Launch the manager from computer properties

Computer manager

If the drivers are installed incorrectly or are not installed at all, the item “ Other devices».

Wi-Fi may also not work due to outdated drivers. In this case, you need to follow the instructions below:

This can also be done using third-party programs that completely automate the search for the necessary programs.

Wi-Fi module is turned off

The drivers may be fine, but the module itself may be disabled. It will look something like this:

All you need to do is right-click and select “ Engage" The name of the item may change depending on the version of the operating system, but its meaning will remain the same.

Turn on the device

No matter how strange it may be, sometimes it happens that people start to panic ahead of time, although in fact the Wi-Fi is simply turned off on the computer.

In order to fix this, you need to use your laptop keyboard find the pictogram with an image of a wireless network and hold it down simultaneously with the Fn key.

If this key does not work or something else prevents you from doing it this way, you can do this through the control panel.

To do this, open it and go to the section “ Network and Internet" Next - in " Network connections" Finding a wireless connection. Then right-click and “Enable”.

Failed to connect to...

There are times when such an error occurs during connection. And there is no clear solution to this problem yet. Most often it's a matter of router settings. First try reboot the router and a laptop. If it doesn’t help, I advise you to roll back the Wi-Fi to factory settings. Or just reconfigure.

Also, sometimes in laptops in the Wi-Fi adapter settings there is a checkmark in the “ Turn off this device to save energy" Because of this, when the laptop is disconnected from the network, such an inconvenience may occur.

You can remove this as follows:

A very common situation: a user tries to connect to Wi-Fi from his phone, but nothing works. After reading the information below, you will learn why this is happening and how to solve the problem.

Initial phone check

Manufacturers are actively working to improve the stability of mobile operating systems, but from time to time any program crashes. That is why it is recommended to start solving the problem by checking the functionality of the phone. For Android, iOS and Windows Phone (Windows Mobile) the recommendations in this case are identical. Follow the sequence below.

1. Restart your device and try connecting to Wi-Fi again.

2. Evaluate the number of connection signal strength indicators. If there are less than 3, try moving closer to the router or other wireless Internet source you are using to improve the quality of the connection.

3. Make sure Battery Saver mode is turned off. If necessary, connect the network adapter.

4. Turn off Bluetooth. Wireless connections may operate in the same range, which causes interference.

5. Turn off Airplane mode, if active.

6. Try to activate access to information about your location and connect to Wi-Fi - the legislation of some countries blocks connections via wireless networks when this option is inactive.

If the WiFi connection worked previously

If you have successfully used the currently problematic network in the past, delete the connection from your phone's memory. To do this, go to the list of networks, click on the problematic connection for a few seconds (until the context menu appears) and delete the connection.

If all else fails, try connecting from your phone to any other available connection. Failure in this case will most likely indicate a breakdown of the radio module - only service center employees will help correct the situation.

Check if the connection is working. To do this, try connecting to it using any other device that has Wi-Fi functionality. If the connection does not work, change the router settings.

Important note! The procedure for entering the router settings varies depending on the manufacturer and model of the equipment. In most cases, to gain access you need to enter the address 192.168.0.0 or 192.168.0.1 into the address bar of your browser. The standard login and password are admin. If this doesn’t work, check the manufacturer’s instructions for the information relevant to your router.

First, try simply rebooting the router - quite often they “freeze”, which is why access to the Internet is blocked.

The further procedure is as follows.

First, you must ensure that the security key you entered is correct. Try entering the password to connect to the selected access point again, but more carefully, with the “Display symbols” (show password) option activated.

If you don't remember the password, check it in the router settings.

As an example, the procedure for interacting with a D-Link router is shown. In your case, everything will be almost the same; minor changes may only affect the interface, menu item names and other little things.

Once on the router settings page, do the following:
click the “Advanced settings” button;
in the Wi-Fi window, open the “Security Settings” link;
in the “PSK encryption key” line, look at the password and make sure that this is the combination you enter when trying to connect to Wi-Fi from your phone.

Secondly, make sure your router settings are correct - you need to check if DHCP is enabled. If it is turned off, the phone will not be able to obtain an IP address, which is why the connection will not work.

On the router settings page, click “Advanced settings” again and in the “Network” window, find the “LAN” category.

Enable DHCP if the function is disabled by changing the “Mode” line to the “Allow” state.

Save the changes, restart the router and try connecting to Wi-Fi from your phone.

If this does not help, there are 3 options left:
call the provider’s support service and find out whether the Internet works at all and whether any changes have been made to the connection settings;
submit your phone for repair;
have your Internet router repaired/replaced.

If our instructions did not help solve the problem, then write in the comments and we will definitely look into your problem.

There can be quite a few reasons why a laptop sees Wi-Fi but does not connect. Let's look at the main factors why this can happen, and also look at how to fix the problem.

In what cases can a problem arise?

The most common problems arise as a result of the following phenomena:

• you didn’t turn on Wi-Fi on your laptop;
• the router settings were set incorrectly;
• the operating system crashed, or the settings of the same router were lost;
• the driver responsible for the operation of the wireless adapter has been damaged (or not installed at all);
• The router module does not work.

What can be done in such situations?

If you need to understand how to connect to Wi-Fi via a laptop -

follow the rules suggested below.

The very first and most common connection problem is a failure in the router settings. Sometimes you have to reconfigure the laptop yourself, sometimes a simple reboot is enough - in any case, first of all, it’s its parameters that are worth checking.

You also need to check whether the router is working correctly. Inspect the device, make sure that the structure is connected to the Internet. Next, pay attention to whether other gadgets see the network - for this you can use a regular phone with Internet access via Wi-Fi. If other gadgets do not see the network, the reason is simple: the connection was interrupted on the router itself.

In this case, you need to reboot the device and then check it again.

No changes? Then try the following:

1. connect to the router using the cord that was originally included with it;

2. go to the browser (you can use any - Opera, Chrome), then enter the following value in the address bar: 192.168.0.1, you can also enter 192.168.1.1, press the enter button;

3. in the window that appears, enter the word admin in the “Username” and “Password” fields, and then click the login button;

4. The “set up Wi-Fi” tab will appear, go to it;

5. Check if the “enable wireless connection” checkbox is checked and click Next.

6. Make settings - if you don’t know them, contact your provider to find out;

The laptop does not connect to the Wi-Fi network, but sees it

The simplest option is that you entered the wrong password. If you cannot remember the password, then you need to do the following:

1, 2, 3 Go to the address 192.168.1.1, as in the previous instructions, click on the “configure manually” button and select the “Wi-Fi” tab;

4. select the tab where you can check the security settings;

5. you will see the line “PSK encryption key”, it will contain your password, which can be changed if desired.

Checking the MAC filter settings

This is the name of the service that filters devices trying to connect to Wi-Fi. To eliminate the cause, disable the filter. You can do this as follows:

1. repeat the steps from the previous instructions and go to the “Wi-Fi” tab;

but select the “MAC filter” tab

2. disable the filter, then click the “Change” button;

6. Another answer to the question why the laptop does not connect to Wi-Fi - the Wi-Fi module of the device itself - that is, the laptop - may be disabled. Check if it is enabled.

Make sure it is working correctly. If the module works, but the laptop still does not want to connect to the network, you need to check the adapter driver:

1. launch the device manager;

(the fastest way is to press the Win+R keys and enter the command mmc devmgmt.msc);

2. in the “Network adapters” branch, select “wireless network”.

Instructions

1. First you need to go to the Network and Sharing Center.
2. Click on the wireless connection with the left mouse button.

3. Now you need to click on the “Properties” button in the window that just opened.

4. Now select the line “IP version 4 (TCP/IPv4)” and click on “Properties”.

5. Select the item to receive IP addresses automatically and do the same with DNS servers.

If you see an exclamation mark next to a module, it is not working correctly. Click on the icon and find out what is causing the problem.

If the problem still cannot be resolved, even though you have already tried all of the above methods, check your wireless connection settings; perhaps this is where the problem lies.

Did you know that our service center provides free delivery of the laptop to the service center? We repair not only laptops, we can do both. So bring your computer and rest assured that it will be repaired.

Transferring data without using cables literally not so long ago seemed like something out of science fiction, but today a wireless WiFi network at home, at work or in the nearest cafe no longer surprises anyone. But even with such a connection, some problems may occur. Connection error is a phenomenon that occurs quite often. Let's look at the most common problems and the simplest methods for eliminating them.

Wireless network connection: no connection. What is the reason?

As for the most common reasons, they can be divided into two main types: hardware problems (non-working hardware) and software errors.

In the first case, as is already clear, you need to carry out a full diagnosis of the equipment, and then make a decision on repairing or replacing it (this applies to network cards, routers, mobile devices, and external or internal Wi-Fi modules). In the second case, there are several situations where there is no wireless network connection (no connection). Among the main ones are the following:

• disabled module or ;
• incorrectly entered password;
• router problems;
• incorrect connection settings;
• missing, incorrectly installed or outdated network device drivers;
• lack of an established network;
• exposure to viruses.

Problems with viruses, for obvious reasons, will not be considered, since any user must take care of protecting their system on their own. We will partially touch on the absence of a network, if for some reason it was installed in the system, but then disappeared (this, unfortunately, also happens). Finally, we will not dwell on the fact that the user may have forgotten or entered the WiFi network password incorrectly, and problems on the part of providers. These situations are not so significant in our case.

Wireless network connection: no connection. What to do in the simplest case?

First, let's look at the simplest situation. Let's say that at some point the wireless network connection is lost. The reason may be a short-term software glitch. What do most users usually do in such cases? They simply reboot the system (after all, everything worked before).

If this does not help, and the time of signal loss is known at least approximately, one of the options for solving the problem that a connection error appears when trying to connect to an existing network can be to simply roll back the system to its previous state through the corresponding section of the “Control Panel”. But, as practice shows, the problem is usually much deeper.

Diagnostics of connection using the system

If for some reason the Wi-Fi wireless network connection disappears, you can find out the reason using Windows tools. If you call up the menu by right-clicking on the network icon in the system tray, you can use the troubleshooting tool in it.

The system will independently carry out the analysis and then produce the appropriate result. Please note: this tool does not fix anything, but only helps determine the essence of the problem.

Checking Wi-Fi module activity

Many experts cite user inattention or negligence as one of the most common reasons for lack of communication.

For the most part, this applies to owners of laptops that do not have a special switch to activate the built-in Wi-Fi module, and turn it on or off by using a combination of a key with a special Fn button. It is clear that even when typing using the so-called hot keys, it was possible to easily and completely accidentally turn off the adapter. Therefore, first you need to make sure that it is in active mode.

Resetting your router

Sometimes the reason that there is no wireless network connection (no connection) can be a short-term malfunction of the router. This situation is most often observed with inexpensive routers of the TP-Link series.

And in this case, it is recommended to use the simplest reset method. You can do two things: either completely turn off the power for about 10 seconds, or press the special reset button on the back of the device and hold it for 30 seconds.

Identifying Network Settings

Now, if it is not detected, let's look at the basic network settings. To view them, you should enter the network and sharing management section from the “Control Panel” or from the click menu on the network connection icon and use the section for changing parameters

Here you need to find the TCP/IPv4 protocol (if IPv6 is not used) and click the properties button. As a rule, most providers provide services for automatically determining parameters, which should be recorded in the settings. It is worth paying attention to the fact that the use of a proxy server for local addresses must be deactivated (unless otherwise provided). Otherwise, you just need to enter all the parameter values ​​in accordance with the settings provided by the provider when connecting.

Correcting connection parameters on the router

If after this the connection problem remains, it may be due to the settings of the router itself.

Just in case, it’s worth entering the router’s settings menu through any web browser by entering the appropriate address (192.168.0.1 or 1.1), and then in the wireless connection section (usually Wireless) make sure that it is active (Enabled).

Troubleshooting driver problems

Another network problem may be that the network card drivers are missing, incorrectly installed, or outdated in the system. You can make sure that the device is not working in the “Device Manager”, which can be called either from the “Control Panel”, or from the computer administration section, or from the “Run” menu using the devmgmt.msc command.

A non-working device will be marked with a yellow marker. This is a direct indication that something is wrong with the driver. But it also happens that it is not displayed among problem devices. This is only due to the fact that the system installs the most suitable driver for it, considering it optimal.

In any case, it will have to be reinstalled or updated. This can be done directly from several menus. It is recommended to first completely remove the old driver, and only then install a new one, but not to choose from what the system offers, but to find the latest software for this device on the Internet in advance.

To avoid doing such things, it is better to install a program like Driver Booster, which will find and install the latest drivers for absolutely all devices. It is clear that to do this, you will have to go with your laptop to the same cafe where there is a connection, and there use the WiFi password to enter the network (after all, there is no connection at home). The update process will take a maximum of 10-15 minutes, after which a reboot will follow.

Reset settings from the command line

If the network is still detected, you can still try the following steps. We call the command line with administrator rights (cmd in the “Run” console), after which we enter the command proxycfg -d, and after pressing the enter key, two more - net stop wuauserv and net start wuauserv (after each - also “Enter”). These simple steps can also help.

If the network is not detected at all...

Finally, the last problem when it is missing It is quite possible that due to some reasons, including the impact of viruses, the previously created network was simply deleted.

In this case, you need to go to the section for managing shared networks and make sure that the wireless network appears in the list of available connections. If there is none, you will have to create it again by selecting the appropriate item. It will take a minimum of time.

If there is a network, but all the above methods for fixing the problem do not help, you can simply try to delete it entirely, then create it again and make the appropriate TCP/IP protocol settings.

Conclusion

In conclusion, it remains to add that these are only the main, most common problems and methods for solving them, which any user can use to resolve failures. Various types of commands that allow for complete testing of IP connections or assigned MAC addresses, pinging, etc., were not specifically considered here, since they may seem quite complicated for ordinary users to understand. In other cases, even the simplest remedies will help. However, this in no way applies to cases where the equipment fails. No software methods will help here, no matter how hard you try.
