Forget the "1394" connection as that is Firewire.
You should initially be connecting to the router with an ethernet cable from the PC's network adapter to one of the router's LAN ports. The PC's network adapter is the "Local Area Connection" in the Network Connections folder. If you cannot then access the router by entering its IP address (192.168.0.1) into a web browser, try allocating a fixed IP address to the Local Area Connection.
Right click the Local Area Connection and select Properties. Highlight the "Internet Protocol (TCP/IP)" entry and click the Properties button. In the next box, select "Use the following IP address" and enter:
IP address - 192.168.0.2
Subnet Mask - 255.255.255.0
Default Gateway - 192.168.0.1 (the Router's IP address).
Then see if you can access the router's Setup by typing 192.168.0.1 into your browser.
