Vista Sleep Problem / Network Problem

When I try to put Vista to Sleep, it'll shut down everything and go to sleep,
and for a split second it'll sleep, but then only right after that "wake back
up" and bring me back to the welcome page. Is there any fix to this? I didn't
have this problem before...

I think this has been mentioned, but I am having problems having Vista
detect Networks. I have already set them all up etc, but everytime i wake
up/restart, it'll identify my network as a "Unidentified Network" It is all
wired and completely worked with RC1. Please help!

- Thanks!

(P.S. I guess thats what beta testers do!)
