Hey all, I have a Dell Latitude E4300 with a missing "network controller" driver in device manager.  This handles the wifi.  wifi works fine when i swap out the hard drive and use windows xp hard drive.  I've looked up the driver on Dell via the service tag of the computer and on Intel Proset section.  I have yet to find the correct match.  Please assist.

Can you locate a wireless driver for Windows Vista on the Dell support website? Vista drivers usually work for Windows 7.

if you have unknown devices in device manager, you can use this precedure to identify them :

Start>Programs>Accessories>System Tools>System Information.
Now select  "Components" and highlight "Problem Devices".
All hardware devices with a driver problem will be listed here.
Make a note of the first line of the PNP Device ID line of the entry. It will show a Vendor number and a Device number (VENxxxxDEVxxxx) both four digits long.
Look up those numbers here:   http://www.pcidatabase.com/index.php

This will tell you the manufacturer and the chip number.  
Check the manufacturer's website first or google them - or post them here

I found the dell driver on their support site through a variety of google searches.  Finally, one came up with the 64 bit version I needed.
