Oh, almost forgot: The command < arp -a > brings up a list of 7 addresses, but is one for the wireless router?
The list of adapters in Device Manager all appear to be internal to the desktop machine.
Complicated setup you got there. I would guess that the router has a non routable IP address like 192.168.0.1. Trying pinging it from a command box to see if you get a return. In the past when I have had to configure a router I would get a sign on screen with the default login Admin, password Admin.
Class C: 192.168.0.0 - 192.168.255.255
