Great card! 1

very good card, cons must update the driver on the intel site and do not let windows 7 that believes that the driver version is the latest out this is not the case.
If this seems too complicated to choose the driver on the intel site, you should use Intel Driver Update Utility 2.0, and it will update the Intel driver for the card.

concerning rates:
(First I have a Freebox Revolution V6 r3 which therefore runs the dual band wifi and AC)

This is a revolution for me anyway: I had a Netgear WPN 311 card, I plafonnais to 2.6 MB / s = 20.8 Mbit / s for real 802.11g wifi to 54 Mbits / s theoretical

The with this Gigabyte WB867D-I card I pass peak is 31 MB / s = 248Mbits / s for the real 802.11ac WiFi to 867 Mbit / s theoretical (I perform this test with test local flow of the Freebox V6 )

with the Intel software / proset I see that I cling to 780 Mbit / s and not to 867 Mbit / s

For Bluetooth I have not really tested, I just verify that it worked, this requires connecting the internal USB cable supplied

I appreciate the magnetized antenna
