I've been having this problem for a while, and I need some help.
I'm unable to connect to Xbox Live. I have a wireless PC with a fast internet connection, which is connected to my Xbox 360 through an ethernet cable. The connection is password protected, which I think is the problem, but I'm not sure how to enter information like that into the Xbox. I've tried bridging the connections, but I get an error saying "To create a Network Bridge, you must select at least two LAN or High-Speed Internet connections that are not being used by Internet Connection Sharing." I use Windows Vista if that helps.
