cant install wifi driver form my inspinron 14

good day fellow dell users,

im having a problem with my new dell inspiron 14.

it has a pre-installed Ubuntu and everything is working fine but when I install windows 8 32 bit or even the 64 bit os.

network controller doesn't work. I installed a lot of drivers suggested by the dell sites but it didn't fix the problem.

i'm currently using windows 8 64 bit.

hope you guys help me for this.

thnks.
