No DHCP Requests from new NIC?

Hey All,

I just picked up two of these dual-gigabit port PCIE NICs on Amazon but I am unable to get either of them to work in Windows 10.

In running Wireshark, I can see DHCP requests being broadcasted (https://imgur.com/SspbxmU) but I never see these hit the interface of the router or the switch at all. The only thing I see on tcpdump on the router is:

16:36:10.244452 00:13:3b:10:12:57 > ff:ff:ff:ff:ff:ff, ethertype 802.1Q (0x8100), length 309: vlan 1, p 0, ethertype IPv4, 169.254.151.96.54915 > 169.254.255.255.54915: UDP, length 263 

Alas, I tried updating drivers, installing latest drivers, installing manufacturer provided drivers, enable/disable offloading, switch to 100Mbps FD/HD, port bouncing, rebooting multiple pieces of equipment, different ports, different cables, disabling primary network adapter -- the list goes on and on...

..but it still does not seem to be responsive to anything DHCP.

I've configured the interface statically in Windows and it STILL will not go any where.

I looked around online but it seems I am the only person in the world to be having this issue.

Any ideas what the issue(s) could be with this damn card or what I'm doing wrong?

Reason I got the card: Connecting second cable + third cable to switchports for different VLANs to run VM's in specific VLANs for labs.
