I currently have a really old WRT54G router with two WD TV Streaming Media Player's each with a HDD connected via wifi. Currently I do not have enough bandwidth to stream larger files (1080p) from one box to the other. The Router is currently located between the two locations, no more than 15 feet apart, but the second location is on a different floor of the home. I want to set it up so that I can effortlessly stream extremely high bit rate films between each location. Wireless N (WD TV live only does 2.4ghz) from what I gather still might not be flawless streaming. The first location could be wired directly to a new router, but the second will only stream. The second location also includes a PS3 and Slingbox For what it's worth. I have considered a RT-AC66U but I wouldn't be able to take advantage of the increased speed so I'll be limited to a mix G/N. However, if I get the AC router and wire to the first location and use a bridge for the second location and wire directly from all my devices to the bridge, will I be able to take full advantage of the AC technology and have no issues streaming? Other than physically running Cat 6 throughout my house, is there a better solution that would work?
