Sophos mini ITX firewall in AP access point mode with Atheros 5GHZ chip

I had this old core i3 motherboard and thought it would be perfect for a firewall. The motherboard has dual Gigabit Ethernet and on board wife. I had to upgrade the Mini pcie card to an Atheros chip to support wireless AP mode. My ASA was bottle necking my bandwidth. I need something that supported IPsec so I could VPN into my Colo.
