Network Controller drivers?

I have an HP Pavilion dv6326us notebook whose original OS is Windows Vista. I formatted my harddrive and reinstalled Xp. The installation went well but I am missing some drivers. I'm trying to get the required drivers to connect to the internet and I think I have most of them, I just need this one.

Any help would be great. I can't find htis anywhere, probably because the name is so vague.

EDIT: I have already checked HP's website. I did not find anything for it. I connected my modem directly to my laptop (for a temporary fix), but it just says the connection is limited. How can I fix this?

EDITEDIT: I ran 'Unknown Devices' and it says that the Detected Chip Vender for 'Network Controller' is Broadcom Corp, and that the OEM Vender is HP.

Get back to the screen posted in your screenshot, and click the details tab...
You should see information that will be on the order of (but probably different)...
PCI\VEN_8086&DEV_4220&SUBSYS_27018086&REV_05\4&16793A72&0&48F0

In my case the VEN/DEV numbers points to
Intel(R) PRO/Wireless 2200BG Network Connection

These numbers will allow you to find the correct driver.
