Internet connections through Ethernet do not have restrictions on the computer as long as there is an Ethernet port. If you are useing a usb or other type of external Ethernet port that did not come with your computer, you would need to find a driver that works with it. If you are useing a router, the router may need to be updated to support Vista depending on how you set it up. I would also check your Bios at start up to make sure that the Ethernet is not disabled by deafult and also any Firewall you have is not blocking it.
Feel free to post back and try to give more information if you can please.
