Vista and Internet connection sharing problem

[sanofi]

I am currently using Vista and would like to share my internet connection for use with my Xbox 360 etc. However, after bridging the two connections (which I used in XP), I keep losing the connection to the net every 20 mins or so.

Anyone know why this would happen?

Not without more detail - what does the other network adapter connect to?
Does it disconnect without the bridging?
What happens when you "lose the connection to the net"?
