Hi Chris, have you found the issue already? If not: what does `top -Sa` show when you're running your speed test? Specifically what does "CPU:" line look like, and what are the top processes in the list? I've had an issue with FreeBSD acting as WAP (although using Atheros-based NIC) some years ago, the problem back then was that the machine CPU was just too slow to process the traffic.
