Media Center Extender - Network Congestion

Media Extenders are particularly useful for streaming video to your TV. Here in the UK the only available Media Extenders you can purchase come in the form of an Xbox 360.

I have been using my Xbox 360 to stream movies stored on my main Media Center PC to my living room over a wireless network (802.11g).

Occasionally I get a "Network Congestion" message appear in the top-right-hand corner, which comes accompanied with a small amount of picture judder/stutter. It's still highly watchable, just a little annoying. Information is available to help you improve your wireless performance; however the crux of the issue is the wireless standards. The Xbox wireless networking adapter supports the following WLAN standards 802.11a, 802.11b and 802.11g. The 802.11n standard has not been ratified by the IEEE yet, but when it comes around it will improve the throughput of data.

The Xbox 360 wireless networking adapter doesn't support any draft version of the 802.11n standard however, so we are stuck with 802.11a,b,g, unless we run an ethernet cable from the router to the Xbox, but that kind of defeats the object, doesn't it?

Microsoft recommends the following:

  • Only have 1 wireless route between your PC -> Router -> Media Extender
  • Use 802.11a standard as it works at 5GHz compared to the congested 2.4GHz channel
  • Use a router designed for Windows XP Media Center Edition

I fairly certain 802.11a is not legal in the UK, can anyone confirm this?
