Hi, I just took one of my blank hard drives and put it into my compaq presario desktop computer and formated windows 7 ultimate onto it. i have it setup as a daul boot computer. i have xp home edition on one drive and win7 on the new drive. i am not having any issues out of xp with the LAC. it picks up the router and has internet access and all. However Win7 did not automatically install drivers for my network card. (it is not wireless, its plugged through a ethernet cable) i inserted the manufacturers cd that came with the network card and installed the drivers. it's a netgear. that picked up the card and made it reconize a network connection. it reads it as a unidentified network, so it's receiving the network connection but has no internet access. when the system trouble shoots the issue, it comes back to "local area connection" has no valid ip configuration. what is the cause of this and does anyone know of a solution? i've been researching it for a couple days now and i see its a common issue but nobody's was exactly like mine so i can't figure out anything to do about it. i want to use windows 7 badly but it's no point without the internet. i'll take all the help i can get. i use verizon dsl, and on my moms laptop the network name is the serial number on the bottom of the router, it supports wireless and ethernet cables so. maybe that will help also.
