Basic home router setup

Anyone has a guide for one? I’m trying to set it up so that I can connect a device to the routerboard, then connect to it via wifi. I added a bridge, enabled the wifi card. My computer will connect to it but cannot get the IP address of the router. I do not need internet. I’m using a 411AH board.

Bridge the wireless interface and the ethernet interface. Put an IP address on the bridge interface.
