Windows was unable to connect to Wi-Fi. What to do with this error? Failed to get network settings from router. System event with a message that it was not possible to connect to the Windows service Why can not connect to this network

The "Windows cannot connect to the 'System Event Notification Service'" error is caused by a failure of services and system components of the system. The cause of the failure may be virus activity, hardware conflict, software incompatibility.

After the error occurs, many system services stop working correctly. The ability to log in under the accounts of other users is disabled. This is one of those cases where it will be easier for a user sitting in the system under an administrator account to fix the problem. Despite the system warning that the error "prevents normal users from logging in," sometimes Windows does not allow you to change your regular account to an administrator account.

A common cause of the error is damage to system files as a result of virus activity. Some troubleshooting methods require you to roll back Windows to a restore point and take other actions that could damage or delete files on your computer. Before starting an independent solution to the problem, you should save all important documents and files, create a restore point (instructions are attached).

Ways to solve the problem:

Using the command line cmd.exe

The "Unable to connect to the service" error can be fixed using the netsh winsock reset and route -f console commands. These commands reset the Windows network settings to the default settings, which allows you to get rid of the error and restore the system and network to working order. Resetting the settings will not fix the cause of the problem: viruses, hardware or software conflict.

After fixing the error, you will need to spend time finding and eliminating the cause of the error. An alternative option is to roll back the system to one of the restore points, when a virus infection or other malfunction has not yet occurred.

The following actions must be performed on behalf of (in the account) administrator:

1. Click Start -> Accessories -> Command Prompt or Start -> Run -> type cmd.exe in the box and press Enter.
2. Enter the route -f command and press Enter. The command will be executed only if you have administrator rights and will clear the routing table of all unnecessary entries. All important network and hub routes remain operational.
3. Type the command netsh winsock reset and press Enter. The command resets one of the key system handlers - Windows Sockets.
4. Restart your computer for the changes to take effect. It's a good idea to bookmark this page in case the notification of Windows not being able to connect to the service bothers you again.

The Windows Sockets handler is modular and multi-tasking, and viruses and other applications can embed themselves in its activity. This mechanism is necessary for the system so that applications can access the Internet quite simply, avoiding unnecessary interaction with drivers. A wide variety of handlers can be built into Windows Sockets, it is used by antiviruses to intercept and scan traffic for threats. If an error occurs at some stage of packet processing, the user will receive a non-working Internet, application crashes and an error with the following content:

Can't connect to Windows service
Windows cannot connect to the "System Event Notification Service" service. This issue prevents users with limited privileges from logging in.
An administrator user can view the system event log to determine the cause of problems.

Restoring a system from a checkpoint

If after using console commands and restarting the computer, the error continues to appear, and the cause of the problem has not been found, you can roll back the system to one of the latest restore points. To use restore points, you need to have them earlier - this feature is disabled on many Windows XP and 7 computers.

Windows will prompt you to select a checkpoint and let you know what data will be deleted or restored. In any case, before starting the recovery process, it is advisable to save the most important files on removable media. It does not hurt to check the files for viruses, especially if the system event service error started to appear after the computer was infected.

Ways to start Windows recovery from a checkpoint:

1. Method 1: Click Start, type Recovery in the search bar and select System Restore from the options that appear.
2. Method 2: Go to Start -> Control Panel -> Backup and Restore, click Restore System Settings or Computer at the bottom of the screen, and then click the Start System Restore button.
3. Method 3: Click Start, type rstrui in the search bar and press Enter. Or enter the same command in the Run menu (Win + R).
4. Method 4: Go to Start -> Control Panel -> System -> System Protection and click on the System Restore button in the window that opens.

Regardless of which of the methods for starting the recovery system is selected, Windows will prompt you to select a checkpoint. It often happens that automatic archiving on a computer is disabled, and the user himself did not make backups.

In this case, the following picture will be observed in the recovery and backup section in the Control Panel:


Even if this is the case, it is still worth trying to start the recovery process. In the "Restore System Files and Settings" window, you need to select the "Choose a different restore point" option to view all available archives.

Windows automatically saves checkpoints after critical system updates and in a number of other cases. When restoring the system from a checkpoint, another restore point will be created with the original state of the files and the system. In other words, the system rollback can then be rolled back, but it is still better to have backup copies of files on external media.

Scanning the system with sfc /scannow

You can run system diagnostics by typing sfc /scannow in Control Panel. In order for Windows to replace missing, corrupted, or deleted files, the drive (or other removable media) must have the same version of Windows as the device. This applies not only to the version of the system itself (XP, 7, 10), but also to the service pack (SP). It is best to use the disk from which Windows was installed on the computer.

To run a system scan, you need:

1. Launch command line. To do this, you need to enter cmd in the search bar in the Start menu, or in the Start -> Run window.
2. Type sfc /scannow and press Enter.
3. Wait for the system diagnostics to finish.

Depending on the recovered files, Windows may require you to restart your computer after the system scan is complete. The result will also be shown: whether it was possible to detect errors at all, whether they were able to be eliminated, whether other problems arose during the check.

You can run a system check without the installation disk. If there are no errors, then the system will not need to restore any files. If errors are found, but the Windows installation disk is missing, then there will be no place to replace the damaged files. You will see a message that reads: Windows Resource Protection found corrupted files but was unable to repair some of them. The path where you can view the check log will also be indicated.

Using Windows Repair Free

You can try to fix the error connecting to the system event notification service using the free version of the Windows Repair program. Before you run the program, you should create a restore point in case of unexpected problems.

Sequencing:

1. Open Start -> Programs -> Accessories -> System Tools -> System Restore.
2. Click "Create a restore point", then "Next", enter the name of the saved point and click the "Create" button again.
3. Wait until the restore point is created, download Windows Repair Free or Windows Repair (all in one) from the official website.
4. Install the program on your computer, run the application.
5. Open tab Step 2 .
6. Click on the Do It button to check the disk. The computer will then automatically restart.
7. After restarting the PC, open the program again, open the Step 3 tab and start the next step by pressing the SFC button.
8. After that, you need to go to the Start Repairs system recovery tab and start the process by clicking on the Start button.
9. The program will prompt you to create a restore point - you should answer "No", since the backup was performed in advance.
10. Next, you need to note the following two items on the left side of the window:
    1. Remove Policies Set By Infections
    2. Set Windows Services To Default Startup
11. Click on the Start button to start the scanning process. The computer should not be used at all while the scan is in progress.

If none of the above methods helped to solve the problem, you should use another method - disconnect all unnecessary devices from the computer. For example, an error can be caused by connecting a microphone, headphones and a music center to a PC at the same time. If the devices are not connected at the same time, the System Event Notification Service error does not occur.

Hello everyone, in this topic we will talk about the problem with connecting to the network. Let's say you have a router with a wireless network function. By Wi-Fi, you can connect to this network and access the Internet. There are cases when it is not possible to connect to the network, in other words, you see this error:. It's pretty sad, but it's worth dealing with.

By the way, you could use the simplest method - forget the network you are trying to connect to. You need to go to the network settings, then to the management of the Wi-Fi network settings, there click on the "Manage known networks" button and find the problem network among the list and click on the "Forget" button, then restart the computer and try to connect again. Unfortunately, this method does not always help, so we will use more effective ones.

I can't connect to the WiFi network, what should I do?

The error of not being able to connect to the network looks like this. And she can appear at any moment.

There are several points why this problem appears:

1. In the parameters of the router itself, you changed the specification from WPA-PSK to WPA2-PSK, or vice versa.
2. Changed the security key in the router settings.

Then you will be prompted, as usual, to enter a new security key, and a message may also pop up that some data has been changed. Try to re-enter the Wi-Fi network key and connect, the new data should be automatically applied.

But here is the case when, instead of requiring the key to be entered, an error appears about the inability to connect to the network.

The first way is "Forget this network"

Yes, at the beginning I said that this method does not always help, but I did not say that it does not help at all.

Click on the Wi-Fi icon on the taskbar, and then go to "Network Settings"

Go to the tab Wifi, if not already on it and scroll to the very bottom, select the item "Manage Wi-Fi network settings", or item Known Network Management.

A window appears where you can see a list of all the networks you have ever connected to. We find ours there, click on it and click on the button "Forget".

Close all windows and click on the taskbar network icon again.We are trying to reconnect to the network by entering the key.

Using this method does not always lead to a positive result.

The second way is "Network Reset"

As far as I remember, this method is only available in the Anniversary Update. You click on the network icon and go to "Network Settings". Go to the tab "State" and scroll down the window. There will be a button "Network Reset". We press it.

A window will appear in which we are told what will happen during the reset. The computer, by the way, will be rebooted. After that, try to reconnect to the network.

Method three - uninstalling the network driver and reinstalling it

The method is somewhat similar to the previous one, but it should not be ignored either. We go to device Manager To do this, right-click on the Start menu and select this item.

Expanding the tab "Network adapters" and device, does not remove only the driver.

After that, restart the computer, the device will be restored, and you will be able to connect to the network.If it doesn’t help, it may be the router and it needs to be reset, but this is the topic of another article.

When I wrote this article, I promised to tell you how to get rid of a similar error in the Windows 8 or Windows 8.1 operating system. The error “The network settings saved on this computer do not match the requirements of this network”, which appears on Windows 7, looks and sounds a little different on Windows 8. It sounds like this: “Cannot connect to this network”, but it looks like this:

Since the error itself and its solution are different, I decided to write a separate article for Windows 8. In which I will tell and show how to get rid of the error “Cannot connect to this network”, which appears when trying to connect to Wi-Fi, or when connecting automatically.

Of course, I don’t know all the possible reasons why this problem appears (even the Windows developers themselves probably don’t know them), but I know one reason for sure. And it's the same as on Windows 7.

As a rule, this error appears after changing the settings of a wireless network to which the computer was already connected. Now I will explain a little more so that you understand what the problem is. We have a computer that runs on the Windows 8 operating system, or 8.1. It is connected to some kind of Wi-Fi network and works successfully (of course, if there is no “Limited” error). And the next time you turn on the computer, you see the inscription “Checking network requirements” and then the error Cannot connect to this network.

Most likely, someone or you yourself changed the wireless network settings on the router. Password, encryption type, security, etc. The settings for this Wi-Fi network that were saved on the computer simply do not match those on the router. Here is the error.

Solution: Can't connect to this network

You just need to forget this network and re-establish the connection. In Windows 8, this is very easy.

Click on the network icon in the notification bar. A panel will open on the right, on which right-click on the network to which the eight does not want to connect. Select an item “Forget this network”.

Open the list of available networks again, click on our network and select connect.

Specify the network password and click Further. If you have changed your password, you must enter a new one. If you changed your password and forgot it, then try to remember. Or make sure your password is correct.

Everything is working. Status Connected, no error.

If there are any problems during the reconnection process, then see another article with possible errors when connecting to Wi-Fi on Windows 8.

If something does not work, write in the comments, I will try to help. If you know other solutions (or reasons) for this problem, you can share in the comments, we will be grateful!

A fairly common problem among Windows users is when a computer cannot connect to a Wi-Fi network. There may be several reasons for this problem. And in this article we will try to touch on all of them.

There are enough reasons why a computer cannot connect to a wireless network. Below we will consider the most common causes in descending order.

[b] Reason 1: Incorrect wireless key entry

Oddly enough, but users have problems connecting to Wi-Fi precisely because of the incorrect password entry.

If you do not remember exactly what your Wi-Fi password looks like, then this information can be obtained by referring to the router settings. To do this, launch any browser and enter [b] in the address bar 192.168.1.1 (less often [b] 192.168.0.1 ) and press the Enter key. Enter your login password to enter the router parameters (usually used as a login and password [b] "admin") and then go to section [b] "Wireless Network" - "Security Key"(name may vary) and view information about the current Wi-Fi password.

When entering a password, pay attention to the keyboard layout, as well as the activity of the Caps Lock key.

[b] Reason 2: Router freezes

If before the computer quietly connected to the wireless network, and then the connection suddenly disappeared, try restarting the router. To do this, turn it off for a couple of minutes, turn it on and wait for it to fully load. After that, check the ability to connect to Wi-Fi.

[b] Reason 3: "glitch" in the Wi-Fi adapter

Try turning your Wi-Fi adapter off and on. If you are the owner of a laptop, then the keyboard shortcut [b] is usually responsible for it Fn+F2.

[b] Reason 4: Incorrect drivers

Click in Windows Explorer on menu [b] "My computer" RMB and select the "Properties" button.

On the left side of the window that appears, select the [b] option "Device Manager".

Expand tab [b] "Network Devices". If you see an exclamation mark next to your Wi-Fi adapter, then the drivers need to be updated. To do this, go to the official website of the laptop manufacturer and download the necessary drivers specifically for your device model. Install the drivers on the laptop, and then reboot it.

[b]P Reason 4: There is a limit on the number of connected devices in the router settings

You, again, need to check the router settings to make sure that the number is set in the settings for a sufficient number of connected devices.

After entering the router settings, go to section [b] "Wireless network" and check the required item. If necessary, expand the number of connected devices and save the settings.

[b] Reason 5: MAC address filter is set in the router settings

It can be assumed that for some reason, the MAC address of your device has been blacklisted, which will block the connection to W-Fi. Often this problem occurs when the router is hacked.

Go to the router settings and select the section [b] "MAC Address Filter" or [b] MAC Filtering and check if any devices are listed there. If they are there, they can be removed from the list. It would also be useful to change the wireless network security key, as well as the password to enter the router settings.

[b] Reason 6: Incorrect settings on the computer

Open [b] "Control Panel" and go to section [b] "Network and Sharing Center".

Click the button with options in the left area of ​​the window.

Right click on your connection and go to step [b] "Properties".

When you suddenly cannot connect to the Internet, any of several things could be wrong. Use the suggestions in this list to find and resolve issues with general Internet connectivity.

Can't you see the obvious?

Disconnected or loose network cables are easy to miss, but one of the most common reasons why you suddenly cannot connect to the Internet. This is not a problem on wireless networks, but on most laptops the Wi-Fi radio can be accidentally turned off. On home networks, it is also possible that someone has disabled router .

Action. Make sure your wired or wireless network equipment is turned on and connected.

False error output

It may seem like a network problem related to the Internet, sometimes just a website (or whatever server on the other end of the connection) is temporarily down.

Action. Before you start connecting to the Internet, try visiting several popular websites instead of just one.

Avoid IP address conflicts

If your computer on the network has the same IP address as another computer, a conflict between them will prevent you from browsing the Internet.

Action. To resolve the IP conflict, follow these instructions to release and renew your IP address. If your network uses static IP addresses, manually change your IP to a different number.

Checking for Computer Firewall Faults

The firewall software that runs on most computers is designed to prevent unwanted network traffic from interfering with its operation. Unfortunately, these software firewalls may not work properly and block valid internet traffic. When two software firewalls, such as Windows Firewall and a third-party product, are installed on the same computer, a conflict between them can also block traffic incorrectly.

Action. If you have recently installed or updated software firewalls on your computer, disable them temporarily to determine if this might be causing your Internet connection issues.

Are you out of wireless signal range?

The performance of Wi-Fi network connections depends on the distance between the device and wireless access point . The farther away from the Wi-Fi device, the slower the local connection is until it breaks completely. Wireless signal interference in an area can also limit the effective range of a Wi-Fi connection. Whenever you can't reach access points , you also can't connect to the internet, obviously.

Action. Use one of these options to measure the strength of your wireless signal and try these ideas to expand your Wi-Fi range.

Has the wireless network configuration changed?

Wi-Fi networks with encryption options such as WPA or WEP enabled require computers to use the appropriate security keys when connecting. If someone changes the encryption keys or passphrase to access point , devices that worked before will suddenly be unable to establish sessions and Internet connections. Similarly (though less likely) if the parameters access points modified to require the use of a specific Wi-Fi channel number, some computers may not detect it.

Action. Confirm that the Wi-Fi channel number and encryption keys are on your router have not been recently changed (contact your network administrator if necessary). Using access points follow the provider's instructions to have them signed.

Checking for Broadband Router or Access Point Problems

Home networks using broadband routers , easier to manage than those who do not, but technical failures with router may also prevent computers from connecting to the Internet. Mistakes router caused by overheating, excessive traffic, or simply a stale block. Typical signs of a flaky router include computers on the network that cannot obtain IP addresses, or a console router does not respond to inquiries.

Action. If possible, check indicators and console router to make sure it works and responds correctly. Troubleshoot if necessary and reboot router .

Are you blocked by a service provider?

Suppliers Internet services (ISP) may block access to your account if you fail to make a payment or otherwise violate the provider's terms of service. Especially when using paid hotspots that are charged by the hour or by the day, sometimes people forget to renew their subscription. Other common reasons an ISP might ban your account include bandwidth throttling, sending spam mail, and uploading illegal or inappropriate content.

Action. Contact your ISP if you suspect that your account has been suspended.

Crash with computer glitches

Computers also suffer from technical failures. Although relatively rare nowadays, a computer's network adapter hardware can fail suddenly due to overheating or age. On the other hand, glitches in the operating system software that controls the adapter can occur frequently, especially with computers that are heavily used. Viruses and worms can also disable or block the computer's network interfaces. Finally, when using a laptop or other mobile device, transporting it from one location to another can damage the state of its network.

Action. Check your computer for malware and remove any found. On Windows computers, try resetting your network connection. Restart your computer if necessary.

Contact your ISP

Those who use the services satellite internet may notice that they cannot connect to the Internet during periods of very bad weather. Providers in dense urban areas (including cellular internet carriers) are sometimes unable to support peaks in network traffic, causing sporadic outages for some customers. Finally, those who subscribe to newer or more complex forms Internet services (eg fixed wireless broadband) may experience more downtime than others as providers face more issues with relatively less mature equipment.

Action. If all else fails, contact your ISP to see if they are experiencing any outages. Some providers also provide advice on troubleshooting connected to their network (sometimes for a fee).
