I have a dual boot with Windows 7 64-Bit and Vista 32-Bit Home Premium. Windows 7 connects to the internet while Vista doesn't? Any suggestions?

Is the lan drivers install for vista? Verify it under device manager>network adapter. Make sure there isn't any exclamation or whatver

I've checked the network adapter. It's doing it job as working and operational. anything else? hmmm?

I've checked the network adapter. It's doing it job as working and operational. anything else? hmmm? Do a ipconfig /all under vista and post the IP here. Other than couldn't connect to the net, is there any error when you open IE in vista and did you try running AV and spyware uitliy on vista? Btw is there any third party firewall on vista other than windows firewall itself?

Have you tried the network diagnostic tool? It's ace and does exactly what it says on the tin.

To continue with Daniel Ho's thoughts, also post the output of ipconfig /all from Win7 on that machine. It'll help as a point of comparison.-Chris[If this post helps to resolve your issue, please click the "Mark as Answer" or "Helpful" button at the top of this message.
