Where can i find drivers for WiFi,Bluetooth,Card Reader drivers for sony vaio vpceg25en windows 7 32bit?

[Robin]

I recently bough sony vaio vpceg25en with windows 7 home basic 64bit. And with the need of some 32bit softwares i downgraded it to windows 7 32bit ultimate.After the install i searched through the internet and found some drivers but they were not working. I noted the hardware versions(Atheros WiFi ar9285 adapter,atheros ar8151 pci-e gigabit ethernet controller,atheros ar3011 Bluetooth adapter) and downloaded wifi driver from atheros website which doesnt work on windows 7.. Please advise me for finding correct drivers
