I will grab a new nic today and try...my options are limited though. 
Here are the nics i can get my hands on

TP-LINK TL-TG3468, 10/100/1000Mbps PCIe Adapter (supported by fbsd?)
Intel (EXPI9301CT) Gigabit CT Desktop Adapter (yet another intel nic)

These are the only two nics the local computer store has in stock. 
Anyone know if the TP LINK is supported? I couldnt find anything to 
suggest it is on google.
