I used my old leftover Apple AirPort Extreme (AE) router. Plugging the Ethernet cable that comes from the Asiair Pro (AAP) into one of the Ethernet *outputs* from the AE router. The AE is configure as a normal wifi router. This way the AAP is part of the local network of the AE. The iPad connects through the AE wifi network to the AAP. The AAP app finds the AAP box immediately and automatically. Works like a charm.
Also, other devices connected to the AE wifi can directly access the memory and images on the AAP. So cool and convenient.
I guess this should work with any router from any manufacturer.
