I'd been having the problem described on http://support.microsoft.com/kb/932345 when using my Xbox as a media center extender with Windows Vista on a gigabit network. The second workaround described in the article worked, but dropping my main machine to 100Mbps wasn't an acceptable long term solution. I finally got around to ordering a new switch that I was hoping would resolve the limitation of the Netgear GS108's 144kB buffer memory was causing. I ordered a Cisco/Linksys SRW2008 managed switch and luckily the problem was solved. I looked at several switches that have larger buffers, but most of the units that were anywhere in a reasonable price range had 16 ports and several fans. While the XBox is still noisy, the last thing I need is more fans in the living room. In addition, the other units also used about twice the power (30+ Watts) which is an unnecesary 24/7 cost I also wanted to avoid. The Linksys SRW2008 has eight ports and is rated at 14W.
