Incorrect configuration of the router
The main and most popular reason is the failure of the router is incorrectly set up. It is produced by using the disk that comes with the router, or via a web browser. To configure through the disc, connect the cable intended for the transmission network to the router, connect the communication cord, which also comes bundled with a personal computer, insert the disk in the drive and follow the instructions to configure the connection.
To configure the router via the web browser, type in the search string, the network address is "192.168.1.1". A window will appear in which you must enter a user name and password. If you set up the base and was not changed by the user, the username and password will be the same. Type in two strings "user" or "admin". One thing will fit. Next, open the control panel of the router. In some models it is entirely in English. Language, as a rule, can be changed in the upper right corner.
The presence of the Russian language depends on the firmware version.
Click "configure Internet connection" and set all the parameters for your provider. Reboot the router. Then call technical support for your network and ask the operator registered the router. After a while the Internet will appear.
The fault of the network card of the router
The next reason of failure of a NIC in the router. She was able to burn because of a power surge in the mains. However, the router can work freely and don't show any symptoms, but the computer will not connect to the network. To detect this problem, connect your PC directly via cable. Call the operator and ask them to test the connection. If it is active, then the router is clearly faulty.
Replace the network adapter is best in the service center.
The lack of network card drivers
It is possible that it is not the router itself. Wi-fi may not operate due to the lack of drivers on the network card of the computer. To update or install the new driver by using a special program such as "Driver Solution" or by using technical support, which is located on the manufacturer's website. The first method is the easiest. All you need to do is install the program and run it. It will automatically detect the device on which you want to install or update the driver.
The complexity of the second method is that you'll have to look for yourself. Usually on the website all the manufacturers of virtually the same sequence of actions. Tab on the home page "Technical support" => "device Drivers" => "used product" => "Series model" => "operating system" => "Select drivers". Most often they are divided into groups for each device. Download need, install it, restart your computer and Wi-fi will appear.
