I have a wireless router with wireless networks as physical interface and a virtual interface. I am trying to set up an Asus AC1900 router loaded with Merlin firmware to function as a wireless repeater bridge for the primary router. The Asus router functions well as a repeater for the physical interface of the primary router, but I can't figure out how to get it to do the same for the primary router's virtual interface. Is there a setting for it or could I achieve it with a command prompt?
