It sounds like you must have removed a panel on the bottom of the laptop and found that model number on the wireless card.
That would NOT likely be mentioned on the Dell site in the drivers for wireless networking adapters, or in Windows where you could easily find it.

Downloads and Drivers -
Beside 6 of 61, click on View all
Open up the Network category - you can use any of several drivers/associated software downloads there that mention they're for the 2100A wireless chip. Some are newer versions than others.
Whichever one you choose, click on it and at the bottom of the page where you download it, READ the Installation directions !
(Or - go to the Intel web site and download the latest available software for the Intel Pro/Wireless 2100A LAN MiniPCI Type 3B Adapter, READ the installation directions.)
You DO NOT install drivers for it (when the software for it has not been installed yet) when Found New Hardware pops up for it !
If you have installed drivers/software for it already, un-install them in Control Panel - Classic view - Add or Remove Programs BEFORE you install the proper drivers/associated software !
Getting a wireless adapter to work properly, and getting a working internet connection with it are two separate things.
Installing the proper drivers for it will result in that it is shown to be working properly in Device Manager.
(E.g. RIGHT click on My Computer - Properties - Hardware - Device Manager - Network adapters)
NOTE that if you are given the choice of installing just the drivers for it, or installing both the drivers and the wireless settings (configuration) program for it, you are usually much better off NOT installing the wireless settings (configuration) program for it, and using XP's built in Wireless Zero support instead.
If you need help getting your wireless adapter's internet connection to work properly, say so, and we'll supply you with instructions.
