I have ASRock Fatal1ty 990fx Killer that has the Atheros AR8161 NIC (branded as Killer LAN). I'm direct connecting to a Motorola SurfBoard 6141 with Cat5e cabling. My Windows 7 Professional is set to auto-negotiation and I'm only getting 100Mbps connection. With the same cable plugged into my MacBook Pro from the modem, I achieve a full Gigabit connection. There seems to be many issues regarding this across the web and I'm looking for a solution that will solve my issue.
I've tried both the Killer LAN driver and the driver directly from Qualcomm.
