XP SP3 doesnt allow driver to get loaded

I purchased a Sony Vaio VGN-CS21GN that comes with preloaded Vista, but i downgraded it to XP sp3 which was provided by Sony too. Now XP does not recognise the wireless network adapter. It says:"Driver not installed". i even tried installing it by downloading it from the intel site, but it does'nt work. The intel network adapter identification utility says:" Wireless LAN hardware not detected." Please help.

Not a problem in xp sp3 under the device manager in system properties you will have a yellow circle and black exclamation mark and probably say unknown device or ethernet device. right click go to properties and in details tab you will see Device ID.. we can track OEM driver from this.

Go down to the keyboard section and download that piece of software and install it. That should take care of the sleep and hibernate buttons not working.

Wlan driver problem in vaio vgn-cs21gn


Hi...
This is Nishit Jadawala from Ahmedabad, India. I am also having the same problem with my Sony Vaio VGN-CS21GN Laptop. WiFi was working perfectly in Vista but when I downgraded it to Windows-XP it started giving me errors that "Driver Not Found for the Device" I have downloaded all the drivers available on internet but nothing worked.
Finally after 8 months of research on this problem, I came to know that there is a bug in the supplied Windows XP-SP3 Operating System. There is a file in Service Pack 3 that doesn't allow drivers to access the hardware of WiFi.
The Solution is you will have to forget the bundled windows XP and upgrade your operating System. Right now better option is to go for windows 7. It dint even asked for any kind of drivers to load. WiFi is also working perfectly on it. The laptop has become more faster & smoother than in windows XP.
For more queries, you can write to me on mail.squarez@gmail.com
Thanks & Regards,

XP Drivers for Sony Vaio VGN-fw230j/b


It's probably not supported Sony.

You can try and downgrade but you might lose some functionality. I downgraded my Vista Gateway laptop to XP but had to spend a lot of time tracking down drivers that would work correctly.

You won't be able to just pop in an XP cd and install. You'll have to jump through a few hoops.

Here's the biggest hoop and guide here:

http://maxeasyguide.blogspot.com/2008/04/preparations-for-winxp-installation-cd.html

Since you have a newer laptop your hard drive uses sata drivers which the XP cd doesn't have built-in.

Let me know if you get stuck or have anymore questions.

I have only some Questions...what is the name of AMILO desktop Pi 3630?...can i change my hardware from vista to exp proffetional sp3?


Hi! What do you mean by what is the "name" of the amilo? It is a fujitsu siemens brand or you ment something else? As for downgrade, you can downgrade vista to xp if you got pro/ultimate of vista, if it came with vista home however, then you won't manage to do that. As for your hardware, well there speaks nothing against downgrading to xp as long as you have the xp drivers for your hw. You may run into audio problems though under xp sp3 if you are using the default hw setup of amilo. Please provide a full detail of your hw if you want to know whether all your hw has drivers for xp sp3. Let me know if this answered your questions :)
