Hi guys! I just bought an HP Pavilion dv6830us Notebook PC with Windows Vista SP1 and I would like to downgrade to XP. At first I was having some trouble trying to install XP on this laptop because of the SATA Drive, I finally got it installed. My only problem is the wireless driver. I installed all the XP drivers that I found in more than 10 websites and my PC seems to be working ok but I can't get the wireless to work, I tried more than 3 different wireless drivers and none of them work. The wireless button is ON so this can't be the problem. Here are a list of website where I got the drivers from (including the wireless drivers that didn't work): http://h10025.www1.hp.com/ewfrf/wc/softwareList?os=228&lc=en&cc=us&dlc=en&product=3686687&lang=en http://forums12.itrc.hp.com/service...47627+1214084413214+28353475&threadId=1230537 Something interesting that I noticed... when I open Device Manager in my laptop I see a question mark for Network Controller and Modem Device on High Definition Audio Bus. Under "Network adapters" I see the following: 1394 Net adapter (I think this is the wireless card that is integrated with my laptop). Realtek (this is the hardware for the ethernet cable). I don't see any question mark for 1394 Net adapter and Realtek. Can somebody please help me with this?
