You are welcome.
Thing is, several people have reported that they have been able to stream video files using "g" and "pre-n" routers. Hopefully some of them will chime in with their thoughts and experiences.
After a week of trials I returned all my high speed routers and adapters, went straight to home depot, picked up connectors, wall plates, drill bits, cat5 cable, etc. Another week later I had a reliable wired network over one half of my house and much peace of mind. Now I can stream movies across the network without having to wonder when the next frame will get dropped; I can even play the same movie on 3 machines simultaneously! My kids now believe I have jedi powers
I plan to install a wired network on the other side of the house too and bridge the two sides using powerline.
