I have a DIR-825. I am looking to improve the speed of the connection of Media Server to my PS3. Current G speed (PS3 limit) aren't fast enough to allow seemless streaming of MP4 files. It stutters something awful. However, it plays straigth rips (original uncompressed VOB fiels) just fine. In order to isolate if it was a connection speed problem, I hard wired my PS3 to the 825. At gigabit speeds, I was shocked to find out that it played the converted mp4 files just fine. When I connected it to my older G router, with 100mbps ports, it started to stutter again. I am looking to add the 1522 to get the 150-300mbps speeds that N is capable of. Howver, I am wondering if that will be enought to enable smooth streaming on the PS3. Btw, the 825/media server and the PS3 are seperated by 1 floor, but less than 25 feet. Does anyone else have this setup? What kind of speeds are you getting? Is it fast enough to enable streamoing of hi-def material?
