Hi, Jerry:
Unfortunately, I won't be able to help you with the information you have provided to me.
I do not know how to troubleshoot wireless connection issues if the network drivers are installed.
Hi, RedlandBlue:
You are not installing the right driver for your wireless card. You need to install the Intel Pro driver for Vista.
Use the second file listed.
Once you are able to connect to the internet, click on the multimedia audio controller in the Device Manager and click on the driver tab. Click on Update Driver. Select the automatic search and Windows Update should download the right audio driver. It may take a few minutes, so just leave it be.
The other driver you need is the card reader driver. Use the Vista one from the nc6400. The one on your PC's support and driver page will install the card reader, but it won't work. The one from the nc6400 is a newer version and the card reader will work with W7 and that driver.
