Poor Network Performance for Media Center

Hi all,

I wanted to see if anyone had any good ideas on how to fix an issue I am having.  I have a Windows Vista Ultimate machine and a XBox 360.  My machine had to be blown away and have Vista reinstalled so I could get SP1 installed on the machine.  After the reinstall of Vista and the install of SP1, my network performance between my PC and the 360 went from being able to stream HD content to not even being able to stream video at all.

My network is a Wireless N, and that setup has not changed.  I did recieve a tip to try and disable the autoleveling, and that improved the signal but still not enough to stream video.

Any ideas would be very welcome.

Can you give some more details about how your network is setup?  Is the Xbox on wireless?  Is the computer on wireless or is it wired to the router?  One place you might want to look is at QOS on the router - try disabling it.

The Xbox is plugged directly into the router, and the PC is wireless.
