I recently purchased a laptop computer with Vista Hoe Premium. I have a computer upstairs that is wired to the router. When I start my laptop everything runs great. I have a internet connection and I can connect to shared files on the other computer running XP. After putting the cover down (sleepmode) sometimes that connection to the other computer is lost but I still have a internet connection. I can hit my router and the internet but it is not seeing my other computer? If I restart I get the connection back. Any idea what is going on besides the OS being Vista?
