I want to make this as clear cut as I can, as I am getting very frustrated with this issue. Here is what I am working with
Asus G51vx Notebook
Xbox 360 Elite
Actiontec GT704 router
First things first, this feature used to work when I connected it to my desktop, but the connection was poor due to distance and full wireless on both ends. This leads me to assume the 360 is not broken, but who knows.
When attempting to setup the 360 as an extender, my laptop will find it, will configure it and find all the media, but fails to complete the final step of connecting. When I test the network connections for Media center on the 360, it is 100% complete, but they will not for the life of me complete the connection.
I have removed the extender on bothe the PC and 360 numerous times and tried again, and even tried removing myself from the Homegroup, thinking maybe that was an issue, but no go.
One last note, I just upgraded from Vista 64 to 7-64 two days ago, and it's important to note that I had the same issue on Vista as I do now.
Here is the official error message I receive:
The Xbox 360 could not connect to the Windows Media Center PC. Turn your Xbox 360 off then on again, and try to connect again."
