The essence of the problem

The concept of the Internet today is very firmly established in our lives, and most people use it fully and everywhere. On the Internet, people are trained and gain knowledge; attend exhibitions and libraries; communicate through social networks and video communicators ( "Skype" , "Viber" , etc.); develop projects; transmit and receive information, letters and documents; learn and share news; watching movies and listening to music and more. Not surprisingly, the ability to access the Internet is supported by many different devices: personal computers, laptops, smartphones, tablets. All of them provide connection to the Internet in different ways: using a cable, using a “Wi-Fi connection” or using mobile access capabilities through the services of mobile operators.

Sometimes devices combine different ways of connecting to the Internet, for example, a laptop can be connected directly with a cable and using a Wi-Fi connection , a smartphone has a Wi-Fi connection and mobile Internet. But sometimes there are various problems with the connection, such as lack of connection, limited connection, lack of access to network drives or browsing web sites, etc. In this case, you encounter problems connecting to the Internet or local network in " Windows . Or get error notifications containing error codes. It happens that the “Ethernet” connection or the “Wi-Fi” function of your laptop does not work, or the connection settings fail. This situation is sad and you are trying to find a way out.

In this article we will try to tell you about the various problems with connecting to the Internet and how to solve them for different types of network and Internet connections in the Windows operating system. Most of the methods in this article will work in all versions of Windows , but some of them will be available only for certain operating systems.

We will try to list the main possible solutions to fix problems related to the network and Internet connection in “Windows” . You should try these solutions one by one. And one of them may be able to assist you in finding and fixing the problems that occurred.

METHOD 1: Run the built-in network troubleshooting tool

The first thing you should try to resolve network connection problems is to activate the built-in troubleshooting tool and network problems in “Windows” . This tool automatically diagnoses and finds the cause of the malfunction, and tries to correct the problem, if possible.

To launch the troubleshooter, right-click the Network icon located in the notification area of ​​the Taskbar and select the Troubleshoot section from the pop-up menu.

A problem detection process will start, the result of which you will see in the Windows Network Diagnostics window.

Wait a few seconds, during this time the tool will diagnose networks, perform troubleshooting, check the Internet connectivity, find the cause of the problem, and show how to fix it.

In most cases, this built-in problem detection tool completely resolves the problem and restores the Internet connection. As a last resort, he will point you to an existing malfunction and prompt you with a solution.

METHOD 2: Use the "Network Reset" function (for Windows 10 only)

Sometimes the built-in troubleshooting tool (described in method 1) cannot fix connectivity issues. Then you need to manually reset the network connection settings and network adapters.

And if you are using the “Windows 10” operating system, you can use the built-in “Network Reset” function to automatically reset the settings of network adapters and network components. This function first removes all installed network adapters and then reinstalls them. It also installs other network components to the initial settings.

The Network Reset feature was added to Windows 10 in the Windows 10 Anniversary Update version (version 1607). This feature was designed to help users solve connectivity issues after upgrading the operating system to "Windows 10" from a previous version of "Windows . " It can also perfectly assist users in troubleshooting network connectivity issues that they may have later on with further use.

To access the Reset Network feature, you just need to do the following:

  1. Open the Settings app in one of three ways of your choice:

    Method 1 : Right-click on the “Start” button or use the “Windows + X” key combination and select the “Settings” section in the pop-up menu.

    Method 2 : Click the "Start" button on the "Taskbar" and select the gear sign in the lower left corner of the pop-up menu.

You will have to reconfigure the settings to connect your personal computer to your home group (the network you trust) in order to share files or access the printer.

METHOD 3: Manually Assign IP Address and DNS

After upgrading previous versions of “Windows” to the latest “Windows 10” operating system, you may have a problem with Internet access. Sometimes this may be due to the problems of your Internet service provider, and you need to wait a few minutes, or contact the support service of the provider.

Now the problem with Internet access should disappear.

METHOD 4: Using Registry Settings

This method is suitable for "Windows 7, 8, 8.1" and only if none of the connection types are displayed in the Network Connections folder. Remember that the procedure for editing the registry requires you to care and accuracy. Otherwise, you can make erroneous changes and disrupt the correct operation of the operating system as a whole or its individual applications. Be sure to save the initial settings before editing the registry. In the main menu, click on the "File" tab and in the menu that opens, select the "Export" section. Title the registry file, select the path to store it, and click "Save . " Now you can always use the saved version of the registry, if the need arises.
