Is the router's IP address definitely 10.1.1.1?
There's no reason why it shouldn't have been configured to use that address, although the default for a D-Link DSL-G604T is 192.168.1.1

Are you saying there are no adapter details shown at all in IPCONFIG? If that's the case, are the network adapters shown in (a) Device Manager and (b) the Network Connections folder?
