Have my computer and my wife's computer network using Ethernet switch. My wifes computer connected to Internet via Actiontec DSL modem. No problem with WinXP but my new computer using Vista x64 OS always loses "Local Area Connection". Easy solve as I since computer diagnoses and states you have no LAN and I reset. But shouldn't have to constantly reset the LAN. Turned off firewall and still happens. Not sure where to begin.
