Assume that the vroadsl connected to ADSL is regarded as a, and the Internet account and password must also be set to. Use another vro as B.
1. If the two routers are connected through a LAN port, it will be much simpler. Router B does not need to be set up, because router B is only regarded as a switch, all IP addresses are allocated through.
2. If router B is connected to the LAN port of route a through the WAN port, the configuration is complicated. Assume that the IP address of the LAN of route A is 192.168.1.1. Now the focus is to set the WAN port of router B, change the connection type of the WAN port to static IP address, and set the IP address to 192.168.1.2 subnet mask 255.255.255.0, the gateway is the IP address of the LAN port of route A. It is set to 192.168.1.1, the DNS is set according to your local conditions, and the LAN port of Route B is set to 192.168.0.1, And the subnet mask is 255.255.255.0. The IP addresses of the two router LAN ports cannot be in the same CIDR block.
Note that the IP address of your computer must be in the same network segment as the LAN port of the route. Otherwise, the router cannot be entered. The premise is that the network cable must be connected first. Try the above two solutions.
