If you have duplicate IP addresses on several routers in your home, it can lead to network conflicts and connectivity issues. In order to solve this problem, you can try the following steps:
1.Determine which router is controlling the Internet accessUsually, the router that connects the modem, such as the optical modem, is the main router and is responsible for controlling the surfing of the Internet. The other router should be connected to the LAN port of the primary router and the IP address should be modified to avoid conflicts.
2.Log in to the main router management interfaceEnter the IP address of the main router in the browser, enter the administrator username and password, and enter the main router management interface.
3.View the assigned IP address:On the management page of the main router, find DHCP Server or IP Address Assignment to view the IP address that has been assigned.
4.Modify the IP address of another router:In order to prevent duplicate IP addresses, other routers need to modify the IP addresses. The IP address can be set manually or the IP address range can be set in the DHCP server to ensure that other routers get a different IP address.
5.Modify the network parameters of other routers:In addition to modifying the IP address, other routers also need to modify the network parameters to ensure that the connection to the main router is normal. This may include modifying parameters such as subnet mask, gateway, DNS, etc.
6.Save the settings and restart the router:After modifying the IP address and other network parameters, save the settings and restart the router. This helps to ensure that all routers are using the new IP address correctly.
7.Check your network connection:Check that all routers are properly connected and that the network connection is working. If you're still having trouble, you can try restarting your modem or contacting your network operator for help.
8.Back up router settings:To avoid future problems, it is advisable to back up your router's settings regularly. This allows for a quick revert to the previous setup in the event of a problem.
In short, if there are several routers with duplicate IP addresses at home, you need to determine which router is controlling the Internet access, and log in to the main router management interface to check and set. Other routers need to modify the IP address and other network parameters to ensure that the connection to the main router is normal. Once you're done setting up, restart your router and check if your network connection is working.
