Dell Inspiron 5150 xp sp2

I recently installed Netgear wireless adapter with Netgear wireless router and have excellent connectivity;the internet apears immediately and stays solid.

However, I never looked at device manager prior to installing these two devices so don't know if the yellow question marks were there or not prior to the wireless installation.

In device manager beneath networking is 'other devices' which has this yellow question mark. Expanded, there are two more yellow question marks.

"Base system device properties" is under 'other devices' then;

1-location PCI bus 0, function1

2-location  PCI bus 0 function 3 wireless connections

This is all the infrmation there is there.

When I click on them I am prompted to reinstall these from cd so I tried running the os cd then the drivers and utilities disk. I did not run the Netgear disk as the tech had me download the latest drivers from the Netgear site. He tested all and said the connection is solid and the question marks are drivers that need installing.

I need some one to tell me how to "know" what I am looking for so perhaps I can go to the Dell download site and download the necessary drivers.

I am getting areas that I am not too sure about so could you please instruct me in an easy to understand way?

Thank you for your help.
