I need help with bridging internet connections!?

[772]

Windows 7 to xbox 360

I've bridged a connection before on windows 7 on this same cpu before. Every time I try to bridge the connection it says "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."

How do I go on from here?
What is the reason why this is happening?

Thanks

Either one of your connections is set up to share an Internet connection, or you are trying to bridge one card. Or ne of them is in another bridge. In normal use there is never a need to use bridging.

bridging and internet connection means that the first device u are connected to uses the IP adderess of the device it is connected to.

for example, if u bridge a router connected to a modem the ip address u get is that of the modem.
if the modem isn't a router (IE it is also bridged) then the IP address is ur internet address as supplied by ur ISP.
