Can't update drivers of my wireless card?

Hello

I was searching for some updates for my intel wifi link 1000BGN
on this site : Intel® Driver Update Utility

i saw that there was a driver 14.3.1.1
so i updated it.
I download it and executed it, there was a little sign of the wireless.
Then the wireless card restarted itself.

However, when i go to the driver details after the installation, the driver is still the old one.

How do i fix this?

EDIT: never mind, but the DRIVER DATE doesnt change

Glad to have helped
