First router is a BT Voyager 205 ADSL Router, which used to connect to the original IP address, without another router.
So you mean 'original' = public IP address allocated to you by your ISP?
Second Router is the Actiontec Wireless Router. This is what the "another router" is. This just connects using a network address rather than my original IP.
By 'network' you mean a private address arange as in RFC 1597 as noted above? This is just a internal range to you home network as it is never directly connected to the internet.
When you take out the Actiontec router, and have the BT enabled, it still connects to a network IP.
The Actiontec router is most likly using NAT to share your 'original' ip address between multiple machines behind the router (doesn't matter that you may only have one connected). When you connect to a site on the internet your PC sends data to the router, which then goes and gets it for you under its IP and returns the response to you. As it was making the request for you, this is why sites like Whatsmyip still report your 'original' IP rather than your 'network' IP.
This is only an issue if you ever want to connect directly to you pc (behind the router) in that case you have to start using port forwarding. basically as you only have one really address and, say, ten internal ones, you have to tell that firewall that a certian port (say 80 for web) relates to a certain machine. But that a whole other story.
