82579V network adaptater settings reset

Hi,

I got a Gigabyte GA-Z77X-UD5H motherboard with a Intel 82579V network adaptater, and running Windows 7 64 bits.

My issue is whenever I change some adaptater options (through the device manager), they always disable themselves when I go back to the settings, like the Large Send Offload and Checksum Offload. They are quite critical ones, it's like disabling hardware capability of the device.

Is there a way to force it enabled ?

Thanks.
