I had a similar problem when loading XP onto a laptop that had been running Vista. I didn't have the wireless network
driver for it. So ...
- Open System Properties.
- Click on Device Manager
- Scroll down to the Network Adapters section
- Find the wireless card item
- Double-click it
- Select the Details tab
In XP, it showed a text like this. It's the unique ID for the network card.
PCI\VEN_8086&DEV_4229&SUBSYS_11208086&REV_61\4&6C79FC5&0&00E0
On my Win 7 box, I don't get a tangled description like that. Instead, I get plain, readable text:
Intel(R) 82567V-2 Gigabit Network Connection
Either way ... google-search for that text. In my case, I found a web page at Cnet with all the necessary
drivers. They had XP 32-bit, XP 64-bit, Vista 32-bit, Vista 64-bit, Win 7 32-bit, and Win 7 64-bit. They had it all. Easy.
