I've had similar experience with the Sony Vaio. Only few Fn+... keys worked. Solution was the third drivers pack for the laptop which I've installed after long time of trying.
In your case I think there is 2 possible reasons:
- incorrect keyboard driver
- faulty wireless device
So, try to install drivers for it once again. Try to look for updated drivers and install them.
If this doesn't help visit shop where you bought it.
