I have got my second router B connected to the access point of the main router A. B is configured as a wifi extender described in this document: https://openwrt.org/docs/guide-user/network/wifi/relay_configuration The LAN interface ip is: 192.168.2.1 The ip got by the lan ports are: 192.168.1.*
I have another broadband line which I wish to utilize as well. When I plunged it in the wan port of router B. The router seems automatically configured to use WAN as gateway, which can be confirmed with “ip route” and “traceroute” in the console.
However, if I configure the lan ports as static ip: 192.168.2.* and gateway:192.168.2.1. They failed to connect to WAN
