Many have faced such a problem as the lack of Internet access on a computer, laptop or other devices. In this case, the browser displays a message: "The web page is not available" or a similar inscription. Frequent culprits for this are: an accident on the provider's line, a malfunction of home equipment (router, network card, etc.) or incorrect settings. All this can be summed up in two words – “no internet”. And what about those who have a connection that works, but web pages do not open?
This article talks about such situations and how to solve this problem. In the last article, I analyzed the situation when .
The first step is to make sure that Internet access is really present and working correctly. As a rule, other programs that use the network work in such a situation (Skype, ICQ, etc. are available).
But there are cases when they are not there, and it is not possible to install these applications. In this case, you can check the network operation using the command line. To do this, press the key combination Window + R and in the window that appears, enter cmd. A terminal should appear in front of the user, where they enter the ping command (then you can try to enter the address of the Yandex website, for example, it will turn out - ping www.yandex.ru). If the described problem occurs, this command will display a message about the inability to connect to the resource. But at the same time, if you enter ping 8.8.8.8, a message will appear about the successful status.
The causes of the problem when sites do not open can be different. It may be related:
A common culprit in a situation where the browser does not open sites, but Internet access is not closed, is the operation of the DNS server. You can determine this problem in the way described above, when it was necessary to open the command line and ping the address of any resource by domain name and by ip.
Each site has its own location indication number, called an IP address. There are many different resources on the global web, and they all have a unique address. In order not to torment the memory of a person, it was invented to create a service that, when entering the name of a site (for example, Yandex), could determine its IP address.
Sometimes there are situations when the provider's DNS server does not work or the network settings in the router or computer have gone wrong. The reason why the pages of the sites do not open has been clarified, it remains to explain how to solve this problem.
There are two solutions. If the network settings are lost, then here you need to correct them for the correct ones and, if necessary, restart the equipment. In the event of a DNS crash, you can change the settings on the network adapter. To do this, click "Start" - "Control Panel" - "Network and Internet" - "Network and Sharing Center" - "Change network adapter settings". Here, on the “Connected to a local network” icon, right-click and select the “Property” option. Then select the item TCP version 4 and in the window that appears, select the item "Use the following DNS addresses". Below in the window, enter 8.8.8.8 (public Google DNS server) or 77.88.8.8 (public Yandex DNS). Then click the "Save" or "Apply" button. 
To check the work, you can open the command line (Window + R - cmd), then you need to check the connection (for example, with Yandex). Enter the command ping www.ya.ru. With the right actions below, you will be able to see information about the server response time.
Also, the problem when sites do not open in the browser, but there is Internet access and DNS works, may be due to the influence of viruses and malware. In this case, it will help to solve the question “Why are the pages not opening in the browser?” checking the system with specialized programs: AdwCleaner, Malwarebytes Anti-Malware Free, Zemana AntiMalware, etc. These utilities allow you to find malware that has caused problems with opening pages on the Internet.
Another reason why sites are not displayed in the browser may be changes or data entered about an incorrect proxy server. At the same time, the computer is connected to the Internet and the connection works for all parameters.
To fix this situation, you need to get into the browser settings. To do this, go to the control panel, where they select the browser (or browser) properties item. 
In the menu that opens, select the "Connections" tab and click on the "Network settings" button. 
Here, in the window that appears, all parameters are checked, and if they are not needed, they simply erase all the information and select the automatic detection item. 
After that, in browsers, sites should show their pages.
Also, the reason why pages of Internet resources may not open may be an incorrect configuration of the host file. This situation is unlikely, but still worth checking. The host file is intended to record the domain names of sites and their IP addresses, but as a rule it is empty and sends all requests to the DNS server. Sometimes there are situations when a malicious program writes some parameters and the browser becomes inoperable.
To check the file configuration, you need to go to the Windows system folder on drive C. Next, System32\drivers\etc and open host with notepad. As a rule, it has a standard content as shown in the figure: 
If, after the description of localhost (127.0.0.1), there are lines with information about any sites and their domain names, and there is no slash in front of this data, then most likely the browser does not work properly because of them. To fix this situation, you just need to remove these lines and save the changes in the file. After that, you need to restart your computer and try to browse the web again.
The situation when the computer is connected to the network, but the sites are inaccessible to the user is common. In the first place, this is a problem caused by failures on the provider side when the DNS servers are not working. The second most frequent, when Internet resource sites are unavailable, is the impact of malware. In this case, it is recommended to have good anti-virus software and more often to carry out preventive measures to detect viruses.
