I stream HD media over wifi, lots and lots of it. I live in a rented apartment where there're no wired ports available. I tried Belkin Ethernet over power adapter to carry my HD traffic, it failed miserably. Then I tried to bridge my wireless G usb dongle along with my wired nic - it never worked.
Then I went onto buy a "NETGEAR WNDR3400-100NAS IEEE 802.11a/b/g/n 2.4/5GHz Simultaneous Dual Band N600 Wireless Router" and a "NETGEAR WNCE2001 Wireless 802.11b/g/n Ethernet Port Universal WiFi Internet Adapter" as my bridge.
Sadly the bridge is in 2.4Ghz spectrum, and is susceptible to interference, even to microwaves. (2.4Ghz is such a crowded space - microwaves, garage door openers, cordless phones all use it - compared to that, 5.x GHz spectrum is squeaky clean..!)
I returned the 2.4Ghz WNCE2001 bridge and got a "Cisco-Linksys WET610N Dual-Band Wireless-N Gaming and Video Adapter" from Amazon - as implied, this bridge can talk in the 5.x Ghz spectrum. It has been almost a month now, and my HD streaming is working smooth.
Gist: For HD streaming over wifi - go for Wireless N devices in the 5.x Ghz spectrum, you will be happy!
