Is wireless NIC working on DHCP Enforcement NAP Client?

Hi all

There is my environment:

DHCP Server: Windows 2010(NAP on)

NAP Server: Windows2010

DHCP NAP Enforcement Client: Windows 7(a note PC with both lan NIC and wireless NIC)

Wireless AP(no routing)

Now.

It works well when I use the client lan NIC for requesting a IP.

But it does not work when I use the client wireless NIC for requesting a IP through the AP.

From my examintaion the SoH info(option 43) was not sent in dhcp request packet from wireless NIC that was different from lan NIC(SoH info in dhcp request packet)

My question:

Is there any way to make a wireless NIC working on DHCP NAP Enforcement Client. I think it's necessary for the client which only has wireless NIC such as Surface.
