Hello,
I can't even stream 720p video let alone 1080p over wireless to my xbox 360.
1080p video works great over wired of course.
I have the DWA-552 card using this Antenna:

All connected via 802.11n to my DIR 655 (Hardware Version: A2 & Firmware Version: 1.33NA) down stairs many rooms over. I'm up stairs on the second floor, many room over.
Even with the antenna above I only get an average Rate of around 80Mbps and Signal of 50%. Ouch!
Way better though when I was using 802.11g with a Linksys router and adapter.
I pick up an additional 5 wireless routers, from neighbors, in my room which are causing interference. Thankfully I'm the only 1 on channel 11.
Anyhow, with streaming 720p video my xbox 360 must load right from the start and then wants to load every 10 seconds or so. Streaming 1080p is impossible then.
However, tonight I just now bought this Powerline AV Ethernet Adapter Kit:

I'm hoping I will have less interference and be able to play at least 720p videos (as that is most of my video), if not 1080p. God I hope I made the right choice. Even if it does not work out I can use them else where in the house.
I will be sure and update this post once I receive my package, standard 3 day delivery so probably will not arrive until Thursday.
Take Care,
Will
