Can't get IP from modem via DHCP?

[gogeden]

So for some reason I can not get an IP on my Rosewill RC-404 NIC (http://www.newegg.com/Product/Product.aspx?Item=N82E16833166005) when used as a WAN from the modem via DHCP.
I even bought a new modem.

I've done the following:

• Reinstalled version 2.1 of pfSense
• Restarted and factory reset both the old and new modems
• Swapped WAN/LAN duties with the card in question and the LAN card
• Switched from IPv4 to IPv6
• Used an entirely different computer with the same cards
• Exchanged the goofy card with the exact model
• Changed the IRQ number (Had a notification via the BIOS at boot that there was a conflict)

I even had problems with it on a FreeNAS box I have.
The only thing I haven't done is test it with a non-BSD based system.
I'll test the card(s) with Ubuntu GNU/Linux and see what happens.

Has anyone else experienced this?
I've spent about 2 days trying to resolve the issue and really don't understand what's going on here.
