I just read up on this unit and it has most of the same spec as the Pioneer Elite VSX-81TX I just got. The Lan connection in the rear can by used to connect to your existing wired network. IF your running a wireless network all you need to do is purchase 2 powerline adapters (they connet off you router via lanline in to your house wall outlet). That way you don't have to move a PC next to your unit. I use a device made by Netgear (Mp101 music server) that can work wired or wireless and it is connected to my unit and it plays all the music from my PC's, your unit does the same without my extra device. You can find many of these powerline adapters on ebay dirt cheap, remember you need 2, one connected to your router and the other connected to your Yamaha.
