I upgraded to Windows 7 Ultimate and my Local Area Connection disappeared. I cannot see it on network connections or on network adapters in device manager. I am using a wireless lan but to configure some devices I need an ethernet connection.

I tried to install the driver but it says the (newer) driver is older that the installed one, so I assume the network card is installed, but I cannot see it.

My laptop is an HP compaq 6730 and service pack 1 is installed

Upgrade was done from Windows Vista Prof

When you say you upgraded, what OS were you running before? Windows 7 home, Windows XP, etc? –  Tillman32 Apr 27 '13 at 18:23
