On XP, when you go into Network Connections and view the status of your network connection you should be able to see the IP address your PC is assigned.
What version of RAIDiator are you using? 4.1.6 is the latest. If not already using this, update to this using Frontview.
You may also wish to try a direct-connection to rule out a router issue: http://www.readynas.com/forum/faq.php#How_do_I_direct-connect_between_ReadyNAS_and_PC%2FMac%3F
. You would need to set the network connection on your PC to use an IP address in the 192.168.168.x range to do this.

That is your WAN (internet) IP address. This is irrelevant to your issue.
