What make and model of retail computer are you running?Or is this a self built computer? Either way post your computer specs. This way someone can help you.
I've just downgraded my laptop from win 7, to XP (I know you might think WHY?!) but the reason is, I got it as a gift, and it had 1GB ram, so I downloaded a XP copy and using that now the problem is,
- I didnt have a CD with the manufacturer drivers and I forgot to extract them before I cleaned the system
so I tried realtek the first time and it was compatible with both audio & WLan.
