About LinkSprite WiFi Shield for Arduino

Have anyone working on this project with WiFi-Shield 1.0 from LinkSprite.
I look at their datasheet and try to follow the steps that they provide but does not work.
I have Linksys WRT160N as my router with open port 6000 as they want in the tutorial.
When I connect to the server it does not be able to connect with TCP protocol.
I have no way to test the network transfer using the WiFi
