The simplest way I see this being done is the following:

  1. Configure your wired ethernet connection with a static address and subnet with the gateway set to the broadband adapter address and the DNS set to the broadband adapter's DNS servers.
  2. Connect the router to the PC via the WAN port and configure the WAN with a static address on th same subnet as the PC with the gateway set to the IP address of the PC and the DNS servers set to those of the broadband adapter.
  3. Configure the wireless router to provide DHCP to your wireless devices.

This should theoretically allow your traffic from the wireless devices to go through the router to the PC and out over the broadband card.

For example (using Google's DNS servers):

PC:
    IP: 10.11.12.1
    Subnet: 255.255.255.0
    Gateway: YOUR BROADBAND CARD IP
    DNS1: 8.8.8.8
    DNS2: 4.4.4.4

Router Wan:
    IP: 10.11.12.2
    Subnet: 255.255.255.0
    Gateway: 10.11.12.1
    DNS1: 8.8.8.8
    DNS2: 4.4.4.4

Hope this helps.
