I have a high quality home theater system (Panasonic ST series plasma, Marantz receiver, Definitive loud speakers, Roku XDS media box). My Internet service provider is Comcast and using their speed test, I'm seeking over 16-22 mbps at the router and have a Netgear WRN3500 wireless router placed in the next room from where the Roku/TV system sits. On a regular basis when streaming HD films from Netflix, the film will buffer and then stream at a lower speed resulting in not as perfect a picture. While I realize Netflix does not stream at 1080p, it's frustrating.

I've been contemplating replacing the router with a Linksys E3200 or going the powerline route with the NETGEAR XAVB1004 Home Theater system. Does anyone have experience with either of these, and what do you recommend to eliminate the buffering issue?

Thanks.
