Modern sites are more informative than simple book literature. Any resource opens with one click. The necessary material can be compared and supplemented with material from other sites. But all this is just a constant algorithm of actions that is performed using digital technology. The absence or breakdown of such devices makes the sites inaccessible to users.
The most popular reasons why sites do not open are: lack of Internet connection and an error in the system of the computer itself.
Lack of internet connection
The Internet may not be available due to a malfunction of the router. It can be configured in two ways. Automatic - using the disk that comes with it or manual - through the site "192.168.1.1".
Setting up a router using a disk is the easiest way. To do this, insert it into the drive and follow the instructions to make the settings.
The manual method is much more exotic. Log in to your browser and enter the above address. A window should appear in which you must enter your username and password. If the settings were not disabled by the user, then the password and login must match. Enter "user" or "admin" in both lines, one or the other will do. After the user interface is highlighted, try to find where the settings were lost.
Perhaps you just need to re-enter the password that is specified in the contract with the provider.
If the tuning has not borne any fruit, then most likely the matter is in the router itself. Connect the internet cable directly to your computer and call your ISP's technical support. Ask to test the connection. If it is active, then the router is definitely faulty, if not, then the problem is either in the cable or in the provider itself. The operator could have blocked the channel by mistake.
Parental Controls Enabled
Also, the entrance to the site may be blocked due to the parental control included in the antivirus program. This function is designed to control the entrance to web resources that are pre-loaded into the antivirus memory. It is not excluded that the antivirus program may contain a standard selection of such sites that the antivirus considers potentially dangerous. Such settings could have been installed with a new antivirus or later with an update of the anti-virus databases. You can remove this problem both in a simple way - to turn off the antivirus for a while, or in a complex way - to delve into its interface and turn off the function responsible for this type of control.
When you turn off your antivirus program, be sure to turn it back on later.
Error in the computer system
Errors in the system often lead to the failure of various processes occurring in the computer. Such errors can occur due to the overflow of the registry with various "garbage", the installation of conflicting programs, for example, two antiviruses at once, or due to an infection of the system.
To get rid of such problems and normalize the operation of all programs, and specifically the browser with which sites are opened, a universal method should be applied - system rollback. This standard component is installed along with Windows and helps, in the event of various malfunctions, to restore the system to the point where it worked normally.
