i have a gigbyte G21mx-s2 motherboard in my media center, i am on windows seven 64 bit, i have a HP pro Curve gigabit switchand a tp-link router. all my devices are hard wired through the switch and the switch is wied in to the router.
the gigabyte website has no drivers
for this OS on this board. windows update has updated the driver
fairly recently. i am still only showing a speed of 100mbps and the lights on the switch confirm this. other devices on my network are working at 1gbps.
I am using a mixture of cat 6 and cat 5e.
