Windows 7: Network Adapter Not Shown in Network and Sharing Center

I have windows 7 Ultimate installed (was originally installed as a clean install) and have ever since it was RTM. Everything has been running flawlessly and still is except for one thing. My network cards don't show up under Network and Sharing Center, but they do show normally under device manager and my network connection is rock solid. Currenly I'm plugged into a 10/100mb At&t U-Verse Residential Gateway (router). Because of this I can't manage either of my NICs and I can't join my homegroup.

The NICs are intergrated into the motherboard. The NICs are Nvidia nForce adapters.

Does anyone know how I can fix this? Or at least know where I can go to figure this out?

Thank you!!

Have you tried downloading and installing the latest drivers from Nvidia?

Yes I installed the latest drivers earlier today, rebooted and same problem persisted.

Have you tried uninstalling the NIC(s) in device manager?

This will then prompt a re-install from the system which may correct the issue.

I tried this as well and when windows finds the hardware again it fails to install the devices. When I do it a 2nd time it works...but still doesn't show up under Network and Sharing.

Did you get an error message when the install failed?

Do you run AntiVirus on your PC? If so you could try disabling it and trying the NIC un-install/install again. Then check Network and Sharing before re-enabling the AntiVirus.

I was running Kaspersky 2010, but I removed it when all of this started thinking that maybe it had something to do with my problems, but it didn't change anything.

I don't remember if I get an error or if I did what that error is...I'll repeat the steps and post the results later today.

There are errors presented when I did the uninstall / reinstall. I took screenshots, but I am unable to upload them as now the NICs won't install at all. I keep getting "Incorrect Parameter" when I try to install the driver from nvidia.

Does anyone think that a system repair using the windows 7 CD would work for any of this?

Thanks!

Hello jbeck22;

The only time I ever had, or needed, more than one NIC was on a server. Server software may support more than one active NIC at a time, but since Windows 7 is not server class software I am wondering how well it will accept more than one active NIC?

I would suggest going to the BIOS and disabling one of the on-board NICs and trying to configure just the one NIC? Perhaps you will have normal laptop networking with just the one NIC?

Cheers!

I only have 1 cable plugged in at a time. This is a desktop that we are taking about...not laptop. I'm currently researching the most recent BIOS version for my motherboard....Abit KN9-SLI
