David's suggestion to install HP Wireless Assistant causes LAN to start with WIndows.
When I first started uninstalling it several years ago it would cause problems with Windows 7 wireless starting up as default. Research turned up that it needed to be disabled before uninstall which sounded sketchy but nonetheless worked so I even included it in the Clean Reinstall tutorial.
However I don't know exactly how tearing down the laptop and rebuilding it to paste the processor caused this to happen as it was never included in the years-old Clean Reinstall of Vista which I happened to do. Maybe it involves some toggle of the LAN chip which occurred else ways. Any ideas?
Thanks everyone. Rep all around. David I have to spread it since I repped another of your threads earlier.
