If you have a computer and it suddenly stops working - this is a whole tragedy. If the Internet disappears or works very poorly, then this is real grief. How can you not check your email, go to Odnoklassniki or Vkontakte, not chat with friends in a video chat?! Many will more easily endure the lack of hot water in the apartment and food in the refrigerator. Questions immediately arise about what to do now, how to solve problems with the Internet. Let's try to consider the main reasons for the lack of access to the network, as well as ways to solve them.

The main, of course, what could be - a failure in the work of the provider. Therefore, the first thing to do in this case is to call the company that provides you with traffic and tell about the problem. Within a few minutes they will admit their guilt and will quickly remove it or say that it has nothing to do with it, and thenyou will have to think and look for the answer yourself.
Problems with the Internet may be due to malware that has penetrated the computer and blocked the antivirus and access to the network. An attacker can start using the Internet for his own purposes, for example, to send spam to the addresses he has. Don't forget to update your software and anti-virus program regularly.

Users often use routers. The setting of this device may fly off. You need to reconfigure it or use the settings saved in the file.
Sometimes it happens that the problems of the Internet are just that when cleaning the house, the cable from the provider was pulled out. There are times when neighbors in a common corridor damage it. Sometimes a simple restart of the computer can help. Not in the case, of course, when the neighbors tried, but simply when there was a problem with the Internet.
In such situations, Windows 7 has a great advantage over others. It has a built-in troubleshooting wizard. By running it, you can find out about the problems that have arisen and solve them. You just need to have time to click on the "Next" button.

Maybe you just forgot to pay for a service like using the Internet? Go to your personal account on the page of your provider and check it out.
Sometimes there are, at first glance, incomprehensible problems with the Internet. Do you distribute it through a router? There was one computereverything worked great, we bought a laptop, you want to connect it via Wi-Fi, but nothing happens, the inscription pops up: "IP address conflict". In this case, there are two options: pay for the use of a second IP address, or invite a good computer specialist to help you set up network connections correctly.
Actually, if there is no desire to solve the issue of lack of access to the network on your own, you can immediately call a professional in this matter.
Often the Internet is present on the device, but it may not let you go to some individual sites, not run video files. But this is another story that requires separate consideration. And now, everyone, have a good trip through the expanses of the vast Internet network!
