I have the following setup:

* Desktop running Windows 7 RC (32-bit)
* Xbox360 Elite with wireless adapter
* Both devices are connected to a local wireless network (802.11n Draft 2.0 300Mbps)

I went through the setup procedure detailed on [xbox.com](http://support.xbox.com/support/en/us/nxe/GamesandMedia/SharingMedia/MediaCenter/ShareMediaFromMediaCenterPC.aspx), but after I enter the 8-character password - setup process times out after a few minutes.

I have tried disabling Windows firewall on the desktop, but that didn't help.

Has anyone been able to connect Xbox360 to Windows 7 RC over a 802.11-n (Draft 2.0) network?
Any ideas on why the process is failing?
