Hi I'm looking to connect two Powerline or HomePlug adaptors in an "ad hoc" arrangement, but am unsure if this is possible. Is it possible to follow the same procedures in Wifi to create such an "ad hoc" pair? I'm trying to connect two media boxes, not PCs, each with an ethernet port. They've software which permits sharing of content on hard drives connected to them, provided both are on the same network. Thanks!
