Vista - Local area connection always lost

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.

Hi,

To fix this problem on Vista :

1). Control Panel - Network and Sharing Center
2). In the left-hand panel, choose Manage Network Connections
3). In the dialog box which appears, choose "Local Area Connections" (or whatever your connection is which handles both local LAN traffic and Internet), right-click then Properties.
4). Click Continue if you get a UAC warning, then uncheck the box beside Internet Protocol Version 6 (TCP/IPv6). Then OK.

That's it, it should resume the connection from Standby now. TCP/IPv6 is not yet used, all computers still use v4 for the internet. By the time v6 is in use, we will probably be at Windows 10 or so.

DD.

Thanks for reply and I did as you suggested "unchecked the box Internet Protocol Version 6(TCP/IPv6)". And it really has not stopped issue. Whether in standby or shut down .. when the computer boots up the LAN is lost and I have to reconnect. After reconnecting I have done "diagnose and repair" and of course I says everything is fine. I am not sure if it has anything to do with my Actiontec Modem that I use from Qwest for DSL connection .. only reason I mention is the dialogue box suggests it is modem/router issue but that's it. Any suggestions appreciated.
