Vista Doesn't Recognize My LAN connection

I recently built a second PC for myself, and decided to try out Vista on it. It installed flawlessly, but there's one problem. Vista does not seem to be recognizing my LAN connection. I tried hard-wiring it from my modem, to my router, to the Ethernet port on the back of my computer with no success. From there, I tried plugging it straight from my modem to the port on the back of the computer. No success there either. I know that it's not a problem with the motherboard because I installed this program that came with the mobo called 'Expressgate'; and when I run that before my computer loads the OS, the internet works perfectly.

Any help / suggestions would be greatly appreciated!

Thanks in advance,

Rob


Edit: Forgot to say that my other computers (including the one I'm currently posting on), which are XP, are able to connect via an Ethernet cable or wireless adapter.

Check the Device Manager and make sure your NIC is installed correctly; there should be no yellow or red exclamation marks, or 'unknowns devices'.

Brian, thanks for your quick response!

I currently have no 'Network Adapters' section of my Device Manager. There is a section called 'Other Devices' that has Ethernet Controller under it. The Ethernet Controller has a yellow exclamation point next to it, however.

There lies your problem Rob. You will have to identify exactly what kind of adapter you have in your computer, and download and install appropriate drivers for it.

If you bought your computer from a system vendor, you should be able to simply go on that companies support page and enter the service tag on your computer. An appropriate download page will appear.

If not, go to the support page of the network adapters vendor and find the proper drivers for your card.

Hi Rob,

I have checked the specifications of your motherboard and managed to locate a suitable driver: nForce Driver These are the full chipset drivers, including the LAN drivers.

Thanks so much to both of you! My internet works perfectly now
