Thanks Teky
I realise that upgrading one item(router) and not the rest is also a problem. At this time I am also looking at a gigabit switch to connect my NAS-which has a gigabit ethernet card), my new PH A200 in which i plan to put a large 2tb drive, and possibly upgrade my computer's nic card/along with a Thermaltake USB docking station with eSata so that all the machines on that network can transfer data among themselves at very high speeds or video when connected to a projector or . The wireless will be only for streaming, and with many Buffalo wireless points with me I can ensure that the entire house has a good signal. In addition I also am aware of "mesh wireless" options at affordable pricing), which while not Wireless N or Draft N also provide good signal strength for audio usage.
