How I can chagne my IP address if I am using a wireless router assigned IP from my service provider?

Servers want to cheat from other countries so that they think I'm from a different part of the world. I know that you can use free proxy servers, but not very successful. I want to download content is not allowed if you are in the UK, so I want to trick the server to think that I'm from another country and then download the content. I'm using a router wireless IP address assigned by Tiscalli. Is there a way to change the IP address for the content server to think I'm from another country and not from the UK?
