After multiple PCs are connected to the same WiFi, a lan network can be established, and other hosts can be connected through one pc. I want to use ser2net under OpenWRT to collect serial sensor data. After multiple routers are connected to the same main router's WiFi, how can I manage multiple routers in the same network through the pc under the main router? Using OLSR (unsuccessful, I'm not sure if it's a setup issue) or other protocols?
