If, for some reason, your router has ceased to perform its functions properly, you need to change the parameters of its operation. First, you need to clarify the correctness of the specified parameters.

Instructions
Step 1
Sometimes, after a power outage or a sudden power surge in the network, some routers may stop functioning properly. This is due to a glitch in their settings. Turn off any computer connected to the LAN port of the router. Launch any internet browser and open the router settings menu. To do this, enter its IP address in the url field of the browser.
Step 2
Go directly to the Status menu. Check the server connection status. The problem may not be in the settings of the router, but in the properties of the network adapters of computers. If the connection between the network equipment and the provider is not established, then go to the WAN menu.
Step 3
See the active options for this menu. Be sure to check the correctness of the entered data in the following items: Login, Password, DNS-address. Make sure the DHCP function is active. Save the WAN menu settings.
Step 4
Reboot your router. Wait for the device to boot up and connect to the provider's server. Reopen the web interface of its settings and go to the Status menu. If the router gained access to the Internet, and computers still cannot connect to external resources, then open the Route Table menu.
Step 5
Reset all fields in the routing table. Re-register the required gateways. Be sure to check the correctness of the specified parameters. Save the Route Table menu settings and reboot the router again.
Step 6
If, after turning it on, computers gained access to the Internet, but communication between devices within the network was lost, then go to the WAN menu. Check if the NAT function is active. Check the parameters of the Firewall function. Remember that sometimes it is easier to perform a full reset of the router parameters and re-configure this device than to identify the cause of the lack of connection to the Internet or intranet resources.
